(ZOS) Use 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 display as follows:


Tasks

  1. Type RMF on ISPF command line.

  2. Type 3 to see Monitor III choices.

  3. Type S to get Sysplex reports.

  4. Type 1 to see the Sysplex Summary report. We 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

The following is a copy of the PARMLIB member ERBRMFXS: (parmeters beginning with a /* are not used in this example but may be useful to you.
