Setting up SMF

Here is a sample SMFPRMxx member that will create interval records every 2 minutes, and record the following SMF record types:



ACTIVE                      /*ACTIVE SMF RECORDING*/
    DSNAME(&SYSNAME..MAN1, &SYSNAME..MAN2)       /*TWO MAN DATASETS */
    LISTDSN                     /* LIST DATA SET STATUS AT IPL*/
    NOPROMPT                    /* DON'T PROMPT THE OPERATOR  */
    INTVAL(02)                  /* SMF GLOBAL RECORDING INTERVAL */
    SYNCVAL(00)                 /* GLOBAL SYNC VALUE             */
    MAXDORM(3000)               /* WRITE AN IDLE BUFFER AFTER 30 MIN*/
    STATUS(010000)              /* WRITE SMF STATS AFTER 1 HOUR*/
    SID(&SYSNAME(1:4))          /* USE SYSNAME AS SID     */
    SUBSYS(STC,INTERVAL(SMF,SYNC),
                          TYPE(0,30,70:79,88:90,101,110,120))   

Set the SMF recording interval to 2 minutes by using the 'SET SMF=xx' command to activate the SMFPRMxx member from SYSx.PARMLIB. Use the 'D SMF,O' command to display the parameters in effect.

Use a tool like WSWS to simulate an application stress load.

While the transactions are running, switch to SDSF and RMF to observe the transactions.
