TNS-00046:

INTCTL: Could not contact the CMANAGER on address
Cause: There was an attempt to contact a CMANAGER on a specific address which is not responding.
Action: Verify that the TNSNET.ORA file contains that address. Also check that the CMANAGER is actually listening on that address by using the INTCTL STATUS command. If necessary, start the Connection Manager using the INTCTL START command.
