Cause:

 

 

This is an environmental issue unrelated to Data Protection Advisor.   
   
    The issue is related to permissions on the Linux server. While the user may be "root" there are circumstance where this may not be sufficient still. There also can be other security software or requirements on the Linux server. These are managed by the Administrators of the Linux environment.   
   
    In one instance, it was observed that the Linux servers were configured with security software which prevented the DPA installer from creating the required user (apollosuperuser) and group (dpaservices) which are required by the DPA Datastore database.
                                                           

 

 

Resolution:

 

 

The DPA product is functioning as designed.   
   
    The resolution to this issue requires investigation by the Administrators of the affected environment.  This should be investigated with the appropriate vendor if necessary.   
   
    For more information regarding permissions for installation on Linux, please see the DPA Installation and Administration Guide. Review the section for System Requirements -> Permissions.
