Using RMF
RMF can usually be started with the simple S RMF command from the MVS™ console.
The Monitor III data gatherer can be started after RMF with the 'F RMF,S III' modify command. To use the RMF Monitor 3 display, go to the Sysplex Summary and complete the following steps.
Procedure
- Type RMF on ISPF command line.
- Type 3 to see Monitor III choices.
- Type S to get Sysplex reports.
- Type 1 to see the Sysplex Summary report. You can scroll back and forth in time with PF10 and PF11, or over-type the time field. Look at the transactions in the WebSphere® Application Server service and reporting class and note the Average Response time, Transactions per second, and Performance Index. You may also explore further in RMF Monitor III to see the
System Information
report.
Example
Here is a typical RMF
procedure:
//RMF PROC
//IEFPROC EXEC PGM=ERBMFMFC,REGION=0M,PARM='MEMBER(XS)'
//IEFPARM DD DDNAME=IEFRDER
//IEFRDER DD DSN=SYS1.PARMLIB,DISP=SHR
