Installing multiple instances of InputAccel Servers(Ver 6.0)

Installing multiple instances of InputAccel Servers

     Multiple instances of the InputAccel Server can be installed on the same machine. This is also called as side-by-side installation. A maximum of eight instances of InputAccel Server can be installed; although in typical installations, one InputAccel Server per four cores is optimal. Variations in how systems are configured, the types of hardware used, and customer-specific batch processing needs make each situation unique, requiring experimentation to find the best balance between number of processors per instance of the InputAccel Server.

 

Performance benefits of side-by-side installation include:

  • Each InputAccel Server instance runs its VBA engine within its server process, enabling better parallel execution of batches when running on multi-processor machines.


  • Enables InputAccel to be installed in an Active/Active clustered environment.


 

Steps to install multiple instances of InputAccel Servers:

  1. From the Installation Choices menu of the InputAccel setup program, select Step 2 – Install the InputAccel Server. Click Next.
  2. From the Custom Setup window, select features that you want to install, and then click Next. To install multiple instances of the InputAccel Server, make sure that the InputAccel Server feature is selected.
  3. Select the number of InputAccel Server instances to install, and then click Next.
  4. For each instance, click Change to specify a unique location for data files for each InputAccel Server, and then click Next.
  5. Specify whether the server instances will be used in an Active/Active clustered configuration.
  6. In the TCP/IP Settings window:
    • If multiple instances of the InputAccel Server will be used in a clustered configuration, specify the IP address and Port for each server instance. To simplify client module connections, it is recommend using the default port for all server instances.
    • If multiple instances of the InputAccel Server will not be used in a clustered configuration, specify a unique Port for each server instance.
  7. The InputAccel Service Accounts window displays, prompting the user for the run-as credentials to use for new instances being installed. Click Next. Specify whether you want the InputAccel Server to be started as a service automatically when the system starts.
  8. Click Install and then click Finish to complete the installation.
  9. Activate and license all instances of the InputAccel Servers installed.
  10. To verify that multiple instances of the InputAccel Server are installed correctly:
    • Start any module in production mode.


    • When logging on, specify one of the InputAccel Servers and make sure the module connects.


    • Repeat these steps for each InputAccel Server instance.
