We are running Pro*C (2.2) program from application server (Windows NT 4.0). The database is 7.3..4 (different server).

The connection to database itself is failing (EXEC SQL CONNECT .. statement) with the following error.

ORA-01041 : Internal Error. Hostdef does not exist.
Cause The pointer to the HOSTDEF extension in HOSTDEF is null.
Action Report as a bug to customer support.

Note: The database configuration is OK. We are able to connect from SQL*Plus.

Please help me. This is very urgent.

Thanks.

Best Regards.
