ORA-12218: TNS:unacceptable network configuration data

ORA-12218: TNS:unacceptable network configuration data

Cause: Poorly formed network configuration data. For example, a PREFERRED_ CMANAGERS entry may have an incorrect CMANAGER_NAME in the client s TNSNAV.ORA file. Or an Interchange downtime parameter (TIMEOUT_ INTERVAL) on the Navigator may be set to zero in INTCHG.ORA.

Action: Check the entries in TNSNAV.ORA and the Interchange configuration files and correct them. If necessary, talk with your network administrator to determine if the specified Interchanges (Connection Managers) are available and properly configured. Use the Oracle Network Manager to generate the configuration files if necessary.
