How You Determine When Conflict Messages Are Issued

The following table shows who receives ECMF conflict messages.

Type of Conflict:	Who ECMF Informs:
A batch job or system task is holding a resource that a TSO user needs	The TSO user only
A TSO user is holding a resource that a batch job or system task needs	The TSO user and the operator with the job waiting
A batch job or system task is holding a resource that another batch job or system task needs	The operator with the job waiting
A TSO user is holding a resource that another TSO user needs	Both TSO users

To tell ECMF how many seconds to wait before issuing the first conflict message, you need to specify a value for the REPORTAFTER parameter on the QNAME statement. By default, ECMF issues the first message immediately. ECMF automatically reissues conflict messages every 60 seconds until the conflict is resolved. To change this interval, specify the number of seconds ECMF should wait through the REPORTCYCLE parameter on the QNAME statement. For example, if you want ECMF to issue the first conflict message for resources in the SYSIEWLP QNAME class after 5 seconds, and have these messages repeat every 30 seconds, you would specify the following QNAME statement in the MIMQNAME member:

SYSIEWLP ECMF=YES REPORTAFTER=5 REPORTCYCLE=30

Note: For the QNAME SYSDSN, the REPORTCYCLE parameter also affects the way ECMF requeues batch jobs that cannot obtain resources.
