CAUAJM_I_85000 Compliance Application running

CAUAJM_E_85002 Compliance Application terminated with error 
If DBMaint is run manually from the command line, the Compliance App works without error.

Ensure the TNS_ADMIN variable that is read into the Scheduler environment is pointing to the correct location for the tnsnames.ora file. For UNIX, check $AUTOUSER/autosys.sh.<hostname> for the variable setting. On Windows, check the System tab in the AutoSys Administrator.
