03

NOT VALID WHEN MUF DOWN

Reason:

You attempted to execute a function that requires the Multi-User Facility to be running.

Action:

Verify that the Multi-User Facility is inactive by executing either the COMM STATUS console command or the DBUTLTY COMM OPTION=STATUS function.

If the Multi-User Facility you need is active when this error code is generated and you are running multiple Multi-User Facilities, redirect communication to the desired Multi-User Facility through the appropriate System Identifier module (DBSIDPR).
