How You Tell ECMF Whether to Issue Conflict Messages

To receive messages when two or more tasks need access to the same resource at the same time, specify ECMF=YES on a QNAME statement. This tells ECMF to issue conflict messages if a task specifies that QNAME on an ENQ or ISGENQ request and the requested resource already is being used. ECMF conflict messages show the following information about a conflict:

• The QNAME and RNAME associated with the resource
• The name of the task holding the resource
• The name of the system on which the holding task is executing
