Q

Resolving the PDE-POCO11 ORA-12203 error

My laptop has XP, and I installed Oracle 8i Personal Edition and Oracle Form Builder 6i. SQL*PLUS works fine, but every time I try to connect to my database in Procedure Builder, the error "PDE-POCO11 ORA-12203: TNS: unable to connect to the destination" pops up. So can you tell how to solve this problem? Thanks.

This typically happens when the listener that you try to contact (defined by the server and port in your TNSNAMES.ORA file for that TNS alias) is not listening for the database you defined for that TNS alias. Either that, or the listener is not listening for the correct ORACLE_HOME. Make sure that your TNSNAMES.ORA and LISTENER.ORA files are correct on your workstation and server respectively.
