PCC-02104: Unable to connect to Oracle

Answer Posted / guest

Cause: The precompiler could not connect to Oracle with the
username, password, and, if applicable, database link that
was supplied. Note that this is a precompiler message, not a
runtime message. This means that the USERID option value,
either on the command line or in a configuration file, was
incorrect.

Action: Check that the username and password are current and
correct. Run SQL*DBA or SQL*PLUS and verify that connection
can be made using that username and password.

Please add more information about this Error
