MVS log streams

Log streams are MVS™ resources that reside in the coupling facility (if one is used), and in data sets.

All log streams needed by CICS® must be defined to the MVS system logger before CICS can use them. You can either define log streams explicitly, or you can let CICS create them dynamically when they are first used. To enable CICS to create log streams dynamically, you first define model log streams to the MVS system logger. To define explicit log streams and model log streams, use the MVS IXCMIAPU utility.

For information about defining coupling facility log streams and DASD-only log streams, see the CICS Transaction Server for z/OS® Installation Guide. For more information about the coupling facility and defining log structures generally, see OS/390 MVS Setting Up a Sysplex.
