Requirements for using SMF logging

Using SMF logging requires a sysplex in monoplex or multisystem mode. This is true for either coupling facility or DASD-only log streams.
Coupling facility log streams require a coupling facility running coupling facility control code at one of the following levels:
- CFLEVEL 1 with service level 4.03 or higher.
- CFLEVEL 2 or higher.
For either a coupling facility or a DASD-only log stream, system logger requires that you have SMS installed and active at your installation. This is true even if you do not use SMS to manage the DASD log data sets and staging data sets, because system logger uses SMS to allocate data sets, such as the DASD log stream and staging data sets.
