in xymon we sometimes get the following error message output after adding a new database Oracle 10g and Oracle 11g.

ORA-12514:TNS:listener does not currently know of service requested in connect descriptor (IDBD Error: OCIServerAttach)

It's not a configuration error, SID, Port, Servername or IP adress are all configured properly. All other remote applications can connect with this values, only xymon has problems to connect. All our databases are configured in the same way in xymon, but only some of them show the ORA-12514 failure.

well ... it's an oracle client problem. What script are you using to check Oracle databases ?

I have seen this with the "dbcheck.pl" script from the hobbit-perl-client package, but only with older database versions. A possible workaround is to define the connection string in tnsnames.ora, and then configure the dbcheck.ini file with ONLY the SID - no hostname or portnumber. Then it will use the SID to initiate the connection, which the Oracle client will then map via tnsnames.ora to the correct connection settings.
