Monitor database file errors

When your database applications perform actions on your database files, you should monitor messages about file errors that the program detects so that you can take actions to correct the errors.

One or more of the following events occur when error conditions are detected during the processing of a database file:

• Messages can be sent to the program message queue for the program processing the file.
• An inquiry message can be sent to the system operator message queue.
• File errors and diagnostic information can appear to your program as return codes and status information in the file feedback area.
