Hi I'm getting the following error from OMS:-

XP-21161: Database connection attempt has failed

ORA-12545: Connect failed because target host or object does not exist

Cause: Expert was unable to establish the requested
database connection.

Has any one come across this? My tnsnames.ora looks good and I have jdbc connection configured.

It probably means you cannot ping the host specified in your tnsnames.ora file.

Best regards.

Frank
