Vickie pinged me today and told me that after cloning an instance, she was getting this error whenever she tried to login through self service:

"You have encountered an unexpected error. Please contact the System Administrator for assistance."

An examination of Apache and Jserv logs did not show any errors.  However $IAS_ORACLE_HOME/Apache/Jserv/logs/jvm/OACoreGroup.0.stderr had these errors:

A search on metalink showed note 418130.1 which gives this cause and solution:

Cause: Un-synchronized data in APPLSYS.WF_LOCAL_USER_ROLES:HZ_PARTY

Solution:

For non-OATM instances:

sql> 

begin apps.wf_local_synch.BULKSYNCHRONIZATION(P_ORIG_SYSTEM=>'ALL',  

P_PARALLEL_PROCESSES=>2,  

P_LOGGING=>'LOGGING', P_RAISEERRORS=>TRUE,  

P_TEMPTABLESPACE=>'APPLSYSX'); END; / 

For OATM instances:

sql> 

begin apps.wf_local_synch.BULKSYNCHRONIZATION(P_ORIG_SYSTEM=>'ALL',  

P_PARALLEL_PROCESSES=>2,  

P_LOGGING=>'LOGGING', P_RAISEERRORS=>TRUE,  

P_TEMPTABLESPACE=>'APPS_TS_TX_DATA'); 

END; 

/ 

Since we were on an OATM instance, we ran this pl/sql block after logging in as apps:

SQL> begin apps.wf_local_synch.BULKSYNCHRONIZATION(P_ORIG_SYSTEM=>'ALL',
2 P_PARALLEL_PROCESSES=>2,
3 P_LOGGING=>'LOGGING', P_RAISEERRORS=>TRUE,
4 P_TEMPTABLESPACE=>'APPS_TS_TX_DATA'); END;
5 /

PL/SQL procedure successfully completed.

SQL>

There was no need to bounce Apache. After running the above query, we were able to login without issues.
