Re: PLEASE HELP!!! Error ORA-12154

ORA-12154 TNS:Could not resolve service name

Cause:The service name specified is not defined in the TNSNAMES.ORA file. Action:Make the following checks and correct the error:

•Verify that a TNSNAMES.ORA file exists and is in the proper place and accessible. See the operating system specific manual for details on the required name and location.

•Check to see that the service name exists in one of the TNSNAMES.ORA files and add it if necessary.

•Make sure there are no syntax errors anywhere in the file. Particularly look for unmatched parentheses or stray characters. Any error in a TNSNAMES.ORA file makes it unusable. See Chapter 4 in the SQL*Net Administrator's Guide. If possible regenerate the configuration files using the Oracle Network Manager.
