Please refer to RSA Knowledge Base Article 000030327 -- Artifacts to gather in RSA Identity Governance & Lifecycle to find the location of the log files for your specific deployment.
CauseThis issue may occur if the attribute used for the joins in the unification are not able to uniquely resolve the user resulting in a duplicate user entry.
ResolutionThis issue is resolved in the following RSA Identity Governance & Lifecycle patches:
  • RSA Identity Governance & Lifecycle 7.0.2 P07
  • RSA Identity Governance & Lifecycle 7.1.0 P01

The fix works as follows:
In versions where the patch has been applied, if the Identity Data Collectors (IDCs) have been collected before configuring the unification, then the unification screen will prevent the join from being created. 
If the IDCs have not been collected before the unification join has been created, the unification change will be allowed, but duplicate users will be rejected during unification.

NOTE:  If you still encounter this exact error after applying the above patches, please see RSA Knowledge Base Article 000037875 -- Unification fails with ORA-30926: unable to get a stable set of rows in the source tables, ORA-06512: at "AVUSER.UNFC_PROCESSOR", line 47 in RSA Identity Governance & Lifecycle.
  • This issue may be resolved by identifying and removing the duplicate users from the source data. Contact RSA Customer Support for assistance if you are unable to identify which users are not uniquely identified. 
  • Alternatively, you may change the unification configuration to use a different unique identifier for the user join. 
NotesUnification issues may appear similar but have different causes.  If the error does not match exactly, suspect a different issue.  
See article 000035588 - Identity Data Unification failing with "ORA-30926: unable to get a stable set of rows" in RSA Identity Governance and Lifecycle 7.0.2 for similar errors with different causes.
