Recently, the DELLEMC World got concluded with lots of launches and product announcements like Dell 14G PowerEdge Servers. More than 13,000 people converged in Las Vegas this week for Dell EMC World, which is the annual tech conference for Round Rock-based Dell Technologies as can be seen in Figure 1.


Figure 1 : Dell EMC world 2017


In this event, many great products were showcased and also many big announcements were made. The biggest of all the announcements is the release of the DellEMC 14G next generation servers. In this product portfolio, we found some salient features like exponential increase in low latency of NVMe storage and a 50% increase GPU-compute density.Also, there is also a tighter coupling with software defined storage (SDS) environments and Dell’s new OpenManage Enterprise console which is the GUI consolidation of different products that are spread across different areas in a typical data center. This interface is called open Manage console which potentially can control and provision resources across the DELL-EMC environments. It is a single pane of glass to manage all Dell EMC compute and storage units.

Let us now talk a look into some top products that were showcased during the conference. The first product which has a bright future and has a huge potential based on the earlier spectacular run rate  by the earlier versions is XtremIO X2 as depicted in Figure 2.


Figure 2 : XtremIO X2 box


XtremIO X2 offers a 25 percent increase in the data reduction capabilities compared with the previous version, and supports scale-up in addition to scale-out to let customers add additional storage densities to previously deployed nodes while cutting total cost of ownership by half on a per-gigabyte basis. It delivers low latency; unmatched storage efficiency with inline all-the-time data services; rich application integrated copy services; and unprecedented management simplicity.  The USPs for this product can be summarized as follows:-

  • 4 to 20 times data reduction using inline deduplication and compression, XtremIO Virtual Copies, and thin provisioning. Gains two times more XtremIO Virtual Copies.
  • Enhanced Integrated Copy Data Management (iCDM).
  • Multi-dimensional scaling.
  • Elegant software driven performance improvements.
  • Dramatically lower TCO with efficiency guarantees.
  • Enables unique copy data management capabilities to unlock business agility through improved workflows.
  • Reduces costs by one third and provides smaller, incremental scaling options.
  • Provides two times longer storage product lifecycles than traditional arrays.


The next product which comes to my mind is “Next Generation Unity” as depicted in figure 3.


Figure 3 : DELLEMC Unity bo


DELLEMC Unity is the midrange storage portfolio and is optimized for all-flash performance and simplicity. It utilizes CPU and memory optimally with 16 times the storage density, with up to 80 15.3-TB SSDs, and a 30 percent performance improvement over the current generation. They can handle a maximum file size of 256 TB compared with the current 64 TB. Installation takes less than10 minutes, All new Dell EMC Unity models include 4x larger file system with inline file compression, iCDM with snapshot mobility, simpler mapped RAID protection and support for external encryption key management via KMIP (Key Management Interoperability Protocol). Additionally, Dell EMC Unity features an 8x increase in density and 8x more effective file system capacity than its predecessor, 33% faster than previous generations.

In the data protection arena, the product that got released in DELLEMC World 2017 and worth mentioning is the Integrated Data Protection Appliance as depicted in figure 4.


Figure 4 : Data Protection Suite


The Integrated Data Protection Appliance is a new turnkey offering that combines the company's Data Domain backup appliance with a new version of its Data Protection Suite software. The appliance allows customers to go from installation to back up in less than three hours. Dell EMC protects more than 150 PB of data in the cloud, which is 2x better than the closest competitor. Data Protection Suite introduces Disaster Recovery and Protection Storage in the cloud. This appliance takes up to 10X faster time vis-à-vis any other traditional build on other data protection alternatives and 20% faster performance than the closest competitor. It also brings together industry-leading deduplication (average 55:1 deduplication rate) for data residing both on premise and in the cloud.


There are many more products which got unleashed in DELLEMC World and are worth mentioning. I will discuss more about those products in my next blog.

When we look at any typical organization’s pain points, we see that maintaining a stable performance comes at its top priority/challenges with exponential increase in the volume of data along with other following challenges:-


  • Complexity in handling structured & unstructured data with varied business requirements, performance SLAs etc.
  • Different direct and indirect constraints imposed on database Scalability due to various isolated restriction on data center components like servers, networking, storage etc.
  • Manageability and access issues of database as the amount of data generated and collected are exploding.
  • Protecting the data at any cost as it will hit the reputation and goodwill of a company not to mention about the impending costs.
  • Ways to ingest/consume data by eliminating inefficiencies, automating processes and improving productivity.


When I looked into the above challenges, I was trying to think of a single vendor solution which will take care of all the issues mentioned above in a cost effective manner which will not only reduce the Capex and Opex substantially but will also facilitate the Oracle DBAs to contain the daily firefighting.  At this moment I can only think of using Hyperconverged infrastructure(HCI) which will take care of all the issues mentioned above. Within the HCI domain, the Dell EMC VxRack is considered to be the best choice.

Let me now introduce VxRack as depicted in Figure 1. VxRack is a turnkey hyper-converged solution powered by VMware Cloud Foundation. These systems consist of pre-loaded software and compute, storage, and network components in a hyper-converged stack co-engineered by Dell EMC and VMware.VxRack capable of supporting both traditional and cloud-native workloads. VxRack starts with as few as 8 Dell PowerEdge server nodes and scale up by adding nodes one at a time, or scale out by adding racks. The domain of a single VxRack system can be 190+ nodes, spanning more than 8 cabinets, with PowerEdge R630 or R730xd systems that bring greater capacity and 40 percent more CPU performance without costing more money. Anyone who isn’t a hyper-scale provider and/or doesn’t have a vast “hardware as service” team, VxRack is for them.



Figure 1: VxRack Systems




There are 2 flavors of VxRack which work equally well with Oracle databases namely:-

1. Dell EMC VxRack System FLEX (VxRack FLEX)

2. Dell EMC VxRack System SDDC (VxRack SDDC)


The benefits of using VxRack Flex are as follows:-


  • Asymmetric scale: Configure the hyperconverged infrastructure to add compute and storage capabilities to address specific workload requirements of Oracle databases.
  • Bare metal: Use a physical Oracle database infrastructure to fetch data from the hard disk (remain physical) in a hyperconverged infrastructure.
  • Easy provisioning: Use automation to simplify management and storage lifecycle capabilities for efficient installation, running, and performance of Oracle databases.
  • Flexible personality support: Provision for multiple hypervisors and dedicated storage.
  • Elastic: Grow the system with more flexibility and options, as and when required, without application interruption or downtime.
  • Building blocks for growth: Use step-sized building blocks for future data-center environments.
  • Ready to use: Use a preconfigured, loaded, tested, and fully optimized IT stack, which is delivered from the factory as a fully assembled and supported solution to help run Oracle databases with minimal tuning of database configuration and performance parameters.
  • Compelling economics: Use a single support vendor, built-in management reporting, and automated updates to lower the total cost of ownership (TCO) and significantly improve your OPEX and CAPEX


The benefits of using VxRack SDDC are as follows:-

  • Dedicated Resource Pool : Workload domain feature that enables the creation of separate pools of resources that are dedicated to the Oracle databases
  • Lower TCO: Lower cost because the databases are part of a larger standardized infrastructure
  • Better Granularity level management: Ability to specify capacity, performance, and availability characteristics in an isolated workload domain.


VxRack Systems are ideal for Oracle databases because the infrastructure eliminates hardware complexities, and provides flexibility, performance, and protection at enterprise levels. For example, with the current VxRack System setup, database environment can be protected using Avamar software with the Data Domain system, Data Domain with Dell EMC DD Boos software for Oracle, and EMC RecoverPoint for Virtual Machines. Enterprise-class support for the hyperconverged infrastructure with lifecycle-system assurance ensures the best system performance. Other benefits of using VxRack Systems include:


  • All-flash storage configurations maximize performance for mission-critical workloads. You can deliver sub millisecond performance for physical reads and writes for Oracle databases.
  • Extreme scalability, enabling growth and performance by adding nodes. Adding nodes is seamless and non-disruptive to an existing VxRack System, making expansion easy.
  • The advantages of using the VxRack System with Oracle databases include:
  • A hyperconverged solution accelerates standardization, speeds up deployment, and simplifies IT operations.
  • Support for the entire integrated stack is through a single support organization for all layers, which helps to refocus investment from OPEX to CAPEX.
  • The database infrastructure ensures continued compliance with Oracle database licensing.


In my next blog, I will talk more about the details of Oracle Database licensing on VxRack and its components.

Running Oracle database on VxRail can be part of Software Defined Data Center (SDDC).  SDDC is simply the logical extension of server virtualization. Analogous to the way that server virtualization dramatically maximizes the deployment of computing power, the SDDC does the same for all of the resources needed to host an application, including storage, networking and security.


Running Oracle database applications with a software defined datacenter and VxRail hyper-converged architecture, all resources are virtualized so they can be automatically deployed, with little or no human involvement. Database applications can be operational in minutes, shortening time to value and dramatically reducing IT staff time spent on application provisioning and deployment.


Faster Time to Value


The data center today is more than just a cost center—it is viewed by business users and executives as a competitive differentiator and strategic asset. Meeting and exceeding these expectations requires an automated infrastructure that can provision resources in minutes, not weeks, so that key applications are up and running quickly—and delivering business value. In the SDDC, resources are deployed automatically from pools, speeding the time to application rollout and providing an unprecedented degree of flexibility in the data center architecture. As a result, the organization has the agility to respond quickly to changes in the marketplace—and gain competitive advantage.


The integration of Oracle DBaaS into Dell EMC Enterprise Hybrid Cloud fully supports Oracle users with a self-service environment. For IT, this results in an automated, repeatable process that reduces errors and improves time-to-value.


For the end-user to be able to request a multi-node clustered database on-demand, using the self-service portal is highly beneficial. It reduces significant time and effort otherwise required to deploy a cluster manually. The user simply makes the request and then receives an automated email with deployment details when the request is complete.



Minimize IT Spend


By pooling and intelligently assigning resources, the software-defined data center with VxRail maximizes the utilization of the physical infrastructure, extending the value of investments. The SDDC makes use of commodity x86 hardware (now support Dell PowerEdge), cutting capital spend and reducing on-going maintenance expenses compared to proprietary solutions. IT staff devotes less time to routine tasks, maximizing productivity. The net result is a dramatic drop in CapEx and OpEx spend—50 percent and more for some enterprises.


With intelligent Oracle licensing strategy and the effective isolation of virtual machines in a VMware environment, expensive Oracle applications license cost can be dramatically reduced.


Scalability and Performance


Based on VMware vSphere and VSAN software, and built with new Intel Broadwell processors, the VxRail Appliance allows you to start small and grow, scaling capacity and performance easily and non-disruptively. All-flash VxRail Appliances include efficient and in-line deduplication, compression, and erasure coding. With these enterprise-class data services VxRail delivers high performance all-flash with increased usable capacity.


Eliminate Vendor Lock-in


Today’s data center features a staggering array of custom hardware in routers, switches, storage controllers, firewalls, intrusion detection and other components. In the SDDC with VxRail, all of these functions are performed by software running on commodity x86 servers. Instead of being locked in to the vendor’s hardware, IT managers can buy commodity servers in quantity through a competitive bid process. This shift not only saves money, but also avoids situations where problems in the vendor’s manufacturing process or supply chain result in delivery delays and impact data center operations.


The VxRail Series integrates VMware Virtual SAN and virtualization to provide a complete Hyper-converged infrastructure.


VMware Virtual SAN is integrated in your VxRail Appliance to provide Software-Defined Storage (SDS).  Virtual SAN is not a VSA, but is embedded in the ESXi hypervisor kernel’s I/O data path. As a result,  Virtual SAN can deliver the higher performance with minimum CPU and memory overhead.


Virtual SAN pools the VxRail Appliance's internal SSDs and HDDs on the ESXi hosts to present a single datastore for all hosts in the cluster. Virtual SAN uses a highly available, distributed, object-based architecture. Virtual SAN mirrors and distributes the individual virtual disk (VMDK) across the datastore.


Free IT Staff for Innovation


The SDDC with VxRail includes a management framework with built-in intelligence to eliminate complex and brittle management scripts, enabling cloud-scale operations with less manual effort and significant cost savings.


The VxRail Series offers advanced features including automatic deployment, automatic scale out, fault tolerance, and diagnostic logging.


By integrating of Oracle DBaaS into Dell EMC Enterprise Hybrid Cloud, you can quickly and effectively provision, manage, and migrate Oracle Database 12c as a Service with ASM on Enterprise Hybrid Cloud. This includes single-instance and RAC configurations.


With less time spent on routine tasks, IT staff can focus on more strategic tasks that drive innovation—a key management expectation of the corporate IT function today.


Unmatched Efficiency and Resiliency


The SDDC provides a flexible and stable platform for any application, including innovative services such as high-performance computing, big data (Hadoop), and latency-sensitive applications. Provisioning and management are automated by programmable policy-based software. Changes are made and workloads balanced by adjusting the software layer rather than hardware. When a failure occurs, the management software in the SDDC automatically redirects workloads to other servers anywhere in the datacenter, minimizing service-level recovery time and avoiding outages.



More Options for High Availability and Recoverability 


HA solutions for Oracle databases are complex, costly, difficult to maintain, or altogether non-existent. VMware provides a lower cost, yet highly effective HA solution that is optimal for many workloads. If your DR solution is for the database only, you are missing out on DR coverage for the rest of the application stack required to make that database work. VMware encapsulates the application stack and, when coupled with proper configuration and testing of replication, provides as close to perfect recoverability as any solution can get.



Development/Test/QA Process and Flexibility


Developers need systems and data that are like production in every way possible. When they get quick access to production-like development environments, development time is reduced, and features are more robust on release.


Do you want to move your database workload from one licensed server to another? Do you want the advantages of a private, hybrid, or public cloud environment? Do you want to create live data-centers that are thousands of miles apart, and be able to swing back and forth between them? VMware virtualization, coupled with stretch storage solutions from EMC can facilitate these options.


The optimum environment to test on is production itself. That can be risky, however, since the production system needs to keep your organization running. VMware allows you to provide an exact copy of the production environment to the Test/QA team without impacting your critical systems.


Better Security


Not only does VMware create a minimalized attack profile with its small footprint hypervisor, but also advanced security features like Trusted Execution Technology from Intel allow virtual machines to validate security down to the chip level.

new cluster, replicating the configuration, and expanding the datastore in a cluster.


Node failure tolerance


The VxRail Series supports from 0 to 3 node failures, as defined by the VSAN FTT policy.


The VxRail Series implements the standard Virtual SAN policy of one failure by default:


  • An entire node can fail and the system will continue to function.
  • Disk failure cannot affect more than one node. One SSD can fail or as many as three HDDs on the same node can fail.
  • One network port on any node can fail without affecting the node.
  • Network failover is through the virtual switch configuration in ESXi. This is automatically configured by VxRail Manager during initial setup.


Logging and log bundles


The VxRail Series provides logging and log bundles through VxRail Manager.


VxRail Appliance cluster expansion


Your VxRail Appliance cluster can be scaled in single node increments from a minimum of four nodes up

to a maximum of 32 nodes. The VxRail Manager automated installation and scale-out features make it

easy to expand your cluster as your business demands grow.


Each VxRail Appliance holds up to four nodes. If the number of nodes in a cluster is not a multiple of four, you will have a partially populated appliance chassis in the cluster. You can use the empty slots in the chassis for future expansion.


You can mix different VxRail Appliance models in the same cluster. You must adhere to the following

guidelines when deploying a mixed cluster:


  • All appliances in the cluster must be running VxRail Manager version 3.5 or higher.
  • First-generation appliances (sold under the VSPEX BLUE name) can be in the same cluster with VxRail Appliances, as long as they are running VxRail Manager version 3.5 or higher.
  • Appliances using 1GbE networking (VxRail 60 Appliances) cannot be used in clusters with 10GbE networking.
  • 6G hybrid nodes cannot be used in clusters with 12G all-flash nodes.


VxRail Appliance cluster scalability is supported to a maximum of eight appliances or 32 nodes. However, scalability to 16 appliances or 64 nodes per cluster may be allowed. You must submit a request for product qualification (RPQ) to EMC for clusters over 32 nodes.

  Hadoop Architecture and Cluster Deployment


Apache Hadoop is an open-source software framework used for distributed storage and processing of very large data sets. It consists of computer clusters built from commodity hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are a common occurrence and should be automatically handled by the framework.


The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part called MapReduce. Hadoop splits files into large blocks and distributes them across nodes in a cluster. It then transfers packaged code into nodes to process the data in parallel. This approach takes advantage of data locality – nodes manipulating the data they have access to – to allow the dataset to be processed faster and more efficiently than it would be in a more conventional supercomputer architecture that relies on a parallel file system where computation and data are distributed via high-speed networking.


The base Apache Hadoop framework is composed of the following modules:


  • Hadoop Common – contains libraries and utilities needed by other Hadoop modules;
  • Hadoop Distributed File System (HDFS) – a distributed file-system that stores data on commodity machines, providing very high aggregate bandwidth across the cluster;
  • Hadoop YARN – a resource-management platform responsible for managing computing resources in clusters and using them for scheduling of users' applications; and
  • Hadoop MapReduce – an implementation of the MapReduce programming model for large scale data processing.




Installing a Hadoop cluster typically involves unpacking the software on all the machines in the cluster or installing it via a packaging system as appropriate for your operating system. It is important to divide up the hardware into functions.


Typically one machine in the cluster is designated as the NameNode and another machine the as ResourceManager, exclusively. These are the masters. Other services (such as Web App Proxy Server and MapReduce Job History server) are usually run either on dedicated hardware or on shared infrastrucutre, depending upon the load.  The rest of the machines in the cluster act as both DataNode and NodeManager. These are the slaves.


To configure the Hadoop cluster you will need to configure the environment in which the Hadoop daemons execute as well as the configuration parameters for the Hadoop daemons.


HDFS daemons are NameNode, SecondaryNameNode, and DataNode. YARN damones are ResourceManager, NodeManager, and WebAppProxy. If MapReduce is to be used, then the MapReduce Job History Server will also be running. For large installations, these are generally running on separate hosts.


Configuring Environment of Hadoop Daemons


Administrators should use the etc/hadoop/ and optionally the etc/hadoop/ and etc/hadoop/ scripts to do site-specific customization of the Hadoop daemons’ process environment.


At the very least, you must specify the JAVA_HOME so that it is correctly defined on each remote node.


Administrators can configure individual daemons using more configuration options.


Configuring the Hadoop Daemons


The following configuration should be performed by Administrators:

  • Configuring the etc/hadoop/core-site.xml and etc/hadoop/hdfs-site.xml for some important paremeters.
  • Configuring NameNode and DataNode
  • Configuring ResourceManager and NodeManager
  • Configuring History Server
  • Configuring MapReduce Applications
  • Configuring MapReduce JobHistory Server


Monitoring Health of NodeManagers


Hadoop provides a mechanism by which administrators can configure the NodeManager to run an administrator supplied script periodically to determine if a node is healthy or not.


Administrators can determine if the node is in a healthy state by performing any checks of their choice in the script. If the script detects the node to be in an unhealthy state, it must print a line to standard output beginning with the string ERROR. The NodeManager spawns the script periodically and checks its output. If the script’s output contains the string ERROR, as described above, the node’s status is reported as unhealthy and the node is black-listed by the ResourceManager. No further tasks will be assigned to this node. However, the NodeManager continues to run the script, so that if the node becomes healthy again, it will be removed from the blacklisted nodes on the ResourceManager automatically. The node’s health along with the output of the script, if it is unhealthy, is available to the administrator in the ResourceManager web interface. The time since the node was healthy is also displayed on the web interface.


Hadoop Rack Awareness


Many Hadoop components are rack-aware and take advantage of the network topology for performance and safety. Hadoop daemons obtain the rack information of the slaves in the cluster by invoking an administrator configured module. See the Rack Awareness documentation for more specific information.


It is highly recommended configuring rack awareness prior to starting HDFS.




Hadoop uses the Apache log4j via the Apache Commons Logging framework for logging. Edit the etc/hadoop/ file to customize the Hadoop daemons’ logging configuration (log-formats and so on).


Operating the Hadoop Cluster


Once all the necessary configuration is complete, distribute the files to the HADOOP_CONF_DIR directory on all the machines. This should be the same directory on all machines.


In general, it is recommended that HDFS and YARN run as separate users. In the majority of installations, HDFS processes execute as ‘hdfs’. YARN is typically using the ‘yarn’ account.


Hadoop Startup

Start the HDFS NameNode with the following command on the designated node as hdfs:

Start a HDFS DataNode with the following command on each designated node as hdfs:

Start the YARN with the following command, run on the designated ResourceManager as yarn:

Hadoop Shutdown


Stop the NameNode with the following command, run on the designated NameNode as hdfs:

Stop the ResourceManager with the following command, run on the designated ResourceManager as yarn:

Run a script to stop a DataNode as hdfs:

In my previous blog , I was talking about five important features of oracle database 12.2. In this blog I am going to continue the discussion and talk about 5 more important features for the oracle database version 12.2. Lets start with the sixth item now.


The sixth feature is the real time refresh . In addition to ON COMMIT and ON DEMAND refresh, the materialized join views can be refreshed when a DML operation takes place, without the need to commit such a transaction. This is done at the statement level, so it does not update the MV itself. If we query the MV directly, we can also use the FRESH_MV hint to do the same and get the up-to-date data. During the process of retrieving the recent data, Oracle merges the MV log data with the MV itself to return the correct result.


The seventh is the Big Data Management System Infrastructure which takes care of the 4V’s of Big Data   volume, variety, velocity and veracity. This feature allows more users of Hadoop to combine map-reduce processing with the essential database qualities that many applications require. It can access with any language like REST,Java,SQL,Python,R, Scala etc. it can also do analysis of any type of data like SQl , Spark, Graph, Spatial , Machine Learning etc. It can use databases like NoSQL, traditional database and Hadoop data which can be accessed by External tables. External tables are used by both SQL*Loader and Oracle Data Pump, and thus also by the ORACLE_LOADER and ORACLE_DATAPUMP access drivers. The Hadoop Distributed File System (HDFS) and Apache Hive are the other two most important data sources here.


The eighth is the hot cloning of a PDB without application outages/downtime. Cloning of a pluggable database (PDB) resolves the issue of setting the source system to read-only mode before creating a full or snapshot clone of a PDB. With this feature, you can now clone your production PDBs and create point-in-time copies for development or testing without any application outage. This feature eliminates the need to create application outages for the purpose of cloning.


The nineth is the In-Memory FastStart. In-Memory Column Store allows objects (for example, tables, partitions, and subpartitions) to be populated in-memory in a compressed columnar format. Until now, the columnar format has only been available in-memory. That meant that after a database restart, the In-Memory Column Store would have to be populated from scratch using a multiple step process that converts traditional row formatted data into the compressed columnar format and placed in-memory. In-Memory FastStart enables data to be repopulated into the In-Memory Column Store at a much faster rate than previously possible by saving a copy of the data currently populated in the In-Memory Column Store on disk in its compressed columnar format. In-Memory FastStart significantly reduces the time it takes to repopulate data into the In-Memory Column Store after a system restart. This allows businesses to start taking advantage of the analytic query performance benefits of accessing data in a columnar format faster.


The tenth is the Improving Security Posture of the Database. DB Vault is an important security feature in Oracle Database.When we implement DB vault on an existing application, there is always a chance the application will break due to some DBA/human errors. DB vault 12.2 can be enabled in simulation mode to take care of this issue in 12.2. While in simulation mode, nothing will break and subsequently can be fixed with details from the log where we see all the blocked state. Hence, we can work proactively and make sure that everything works and fix all the problems before the actual implementation.Encryption, decryption, and rekeying of existing tablespaces with Transparent Data Encryption (TDE) tablespace is possible now. A TDE tablespace can be deployed, encrypted for migration to an encrypted tablespace without any stoppages. This feature enables automated deep rotation of data encryption keys used by TDE tablespace encryption in the background again without any downtime. Encryption is important, but until now, had to be done offline for existing data. Oracle 12.2 allows online encryption and re-key operations. The command will effect a datafile, copying it to a new encrypted one, then will change the database to start using the new encrypted file, and everything will be done online. Now it is possible to encrypt internal tablespaces (system, sysaux, undo, etc) as well.



In the last 2 blogs I talked about the top 10 features for the new release for oracle 12.2. As I told in my last blog, the new features look very promising but are available in the cloud version presently. We hope it will work well in its on premise versions as well.

Oracle has released its latest version of its database in cloud version.  I am discussing some ten important features of its latest version.

Firstly, let me talk about sharding as it is the most important feature in this release.

Sharding is an application-managed scaling technique using many independent databases. It is basically the horizontal partitioning of data across independent databases Data which holds the many partitions or splits into multiple databases are called shards which are distributed as data volumes . Each database holds a subset (either range or hash) of the data. Also each shard has its own CPU, memory, flash & disk and holds a portion of rows from partitioned tables and replicated for high availability and sclability. It is like the "scale-up" vertical partitioning, followed by "scaled-out" horizontal partitioning. Sharding is the dominant approach for scaling massive websites. Shardingis used in custom applications that require extreme scalability and are willing to make a number of tradeoffs to achieve it. In sharding , application code dispatches request to a specific database based on key value and then queries are constructed on shard-key. Here, data is de-normalized to avoid cross-shard operations (no joins).It also has “fault Isolation” feature. The sharding can be illustrated in Figure 1 :-


Figure 1: Pictorial representation DB sharding


The second important feature is the PDB level controls that help to limit I/O and are provided in the new release by MAX_IOPS parameter. We can specify the limit as either I/O requests per second or as Mbps (megabytes of I/O per second). This limit can only be applied to a PDB, not to the multitenant container database (CDB) or a non-CDB.


The third one is the Auto-list partitioning which is an extension of list partitioning. It enables the automatic creation of partitions for new values inserted into the partitioned table. Auto-list partitioning helps DBAs to maintain a list of partitioned tables for a large number of distinct key values that require individual partitions. It also automatically copes with the unplanned partition key values without the need of a DEFAULT.


The fourth is the adaptive query optimization which has brought the biggest change to the optimizer in Oracle Database 12c. It is a set of capabilities that enable the optimizer to make run-time adjustments to execution plans and discover additional information that can lead to better statistics when especially, existing statistics are not sufficient to generate an optimal plan. There are two distinct aspects in Adaptive Query Optimization: adaptive plans, which focuses on improving the execution of a query and adaptive statistics, which uses additional information to improve query execution plans. Below is the illustrative diagram :-


Figure 2:  The components that make up the new Adaptive Query Optimization functionality


The fifth is the additional column incorporation while creating indexes  . Also indexes will gather extended stats by default when queries are run such as number of times the index was used, last usage time and much more. All the information is recorded in the DBA_INDEX_USAGE data dictionary view.Index monitoring before 12.2  had many problems. In 12.2, Index monitoring is now enabled by default, tracks the usage during run-time (as opposed to parse level).



The new features for 12.2 will definitely take care some of the shortcomings which existed in the earlier versions of Oracle database . I found these features helpful but we need to test/observe how it pans out in the on premise environment which will be released very shortly. In part-II of my blog, I am going to discuss some more features for 12. 2 database.

  Why Dell EMC Enterprise Hybrid Cloud for DBaaS - Part III

How EHC 4.0 Help Enterprises to Build Up Oracle Database as a Service


In the Part I and Part II of this series, I briefly covered why the most of organization IT choose Hybrid Cloud as their IT-as-a Service infrastructure, compared both Public and Private Cloud, and the benefit of Hybrid Cloud, and discussed on how EHC 4.0 provide cloud services.  In this Part III I will talk about how to quickly and effectively provision, manage, and migrate Oracle Database 12c as a Service with ASM on Enterprise Hybrid Cloud 4.o. This includes single-instance and RAC configurations.



The integration of Oracle DBaaS into Enterprise Hybrid Cloud fully supports Oracle users with a self-service environment. For IT, this results in an automated, repeatable process that reduces errors and improves time-to-value.


For the end-user to be able to request a multi-node clustered database on-demand, using the self-service portal is highly beneficial. It reduces significant time and effort otherwise required to deploy a cluster manually. The user simply makes the request and then receives an automated email with deployment details when the request is complete.


This Oracle DBaaS solution has been built and validated on a number of iterations and configurations of Enterprise Hybrid Cloud . The underlying physical environment is abstracted from the application layer by virtual and software-defined components.



This solution enables the deployment of Oracle DBaaS on Enterprise Hybrid Cloud:


-  The Workload Pod for Oracle DBaaS improves management of Oracle licensing compliance.


-  Application developers and service users can self-provision Oracle DBaaS on Enterprise Hybrid Cloud as:

•    A single-instance Oracle Database with Oracle Automatic Storage Management (ASM)

•    An Oracle Database with Oracle Real Application Clusters (RAC) and ASM

      This creates an Oracle 12c Container Database (CDB) with an optional Pluggable Database (PDB) in a single-tenant configuration.


-  The solution allows users to perform Oracle DBaaS Day 2 Operations:

•    Add disks to Oracle ASM Disk Groups – single-instance and RAC

•    Migrate a PDB to an Oracle 12c CDB deployed on Enterprise Hybrid Cloud

•    Add and remove Oracle DBaaS monitoring


-  Enable monitoring of the complete Oracle DBaaS solution by using Oracle Enterprise Manager Cloud Control 12c (OEM) and VMware vRealize Operations Manager.





The new face of IT:  Database automation



Requesting an Oracle Database - Fast simple form that can be completed in minutes




EHC configuration for Oracle DBaaS - Key components




Provisioning an Oracle Database preparation - Customizable by the IT organization




Oracle DBaaS deployment process - behind the scenes




PDB migration - moving a PDB from one CDB to another





Oracle DBaaS Day 2 Operations - Database customization




Day 2 operations of EHC automates routine tasks - adding new ASM disk group




Easily add or remove OEM 12c agent - EHC automates routine tasks




Day 2 operations of EHC automates routine tasks - Adding vCPU & memory




Monitoring Oracle DBaaS





Use existing Oracle tools OEM Express 12c - No need for new tools as DBAs can use what they have today




Use existing Oracle tools OEM Cloud Control 12c - no need for new tools  as DBAs can use what they have today




vRealize operation manager - EHC management




Enterprise Hybrid Cloud enables customers to build an enterprise-class, multitenant, scalable platform for complete infrastructure service lifecycle management.


This solution incorporates the following concepts:

  • Self-service and automation
  • Multi-tenancy and secure separation
  • Workload-optimized storage
  • Security and compliance
  • Monitoring and service assurance
