Migrating SMF from Data Set Recording to Log Stream Logging
E. Ozan Baran, Andrew M. Sica · 2008
Beginning with z/OS V1R9, the System Management Facility (SMF) can be configured to use System Logger to write records to log streams. This paper gives an overview of the benefits of migrating SMF to log streams, reviews performance considerations and will describe a migration process using the z/OS Integration Test environment as an example. Advantages to recording SMF data in Log Streams The SMF exploitation of System Logger services provides many benefits to the user: 1 Performance With SMF support of log streams, SMF data is captured faster than if using MANx data sets. In addition, since System Logger manages data flow and available storage, there is no concern over buffer overrun due to MANx data set switch processing. This support allows for more efficient dumping, as dump processing can be run against a given log stream which may hold just a subset
