We run the Oracle probe on 6 probe servers (along with other probes). Yesterday, one of the oracle probes started generating the following error for ALL Oracle databases configured for remote monitoring on that probe server.
TNS:protocol adapter not loadable
I rebooted the probe server and verified no changes were performed on the server - no change.
oracle: testClient starting with: user: , conn:
oracle: Profile: test connection, data engine connecting to database , using connection test connection, user:
oracle: Profile: test connection, Oracle error! Status: -1, - ORA-12557: TNS:protocol adapter not loadable
oracle: Profile test connection/test connection, OCIServerAttach failed with rc= -1
oracle: Profile test connection, disconnect starting
oracle: Profile test connection, disconnect finshed
oracle: Connection test to failed
Please advise where I should look to resolve this.
