Probably the Oracle client file tnsnames.ora is not set up correctly or the Oracle environment variables (especially ORACLE_HOME) are not set up correctly so that tnsnames.ora can not even be found.

To verify Ray's suggestion try

Code: Select all

tnsping {SID}

to test if your paths are set up and whether Oracle client can see the specified instance.

you need to check TNS entries in tnsnames.ora file.

This file can be located in $ORACLE_HOME/network/admin directory.

check if you can tnsping your database server from unix prompt.

>tnsping <database>.<domain>

I would think the first question should be - is there an Oracle client installed on the DataStage server?
