Issue Commands in a Sysplex Environment

The following console commands are specific to use of CA Mainframe Application Tuner in a sysplex environment. These commands permit you to shut down all servers within the sysplex group or temporarily change a parameter for one or more servers in an XCF group.

To shut down all servers, issue the following command:

F MATUNER,PERFORM SHUTDOWN TARGSYS1(*)

To change a parameter for one or more servers in an XCF group, issue the following command:

F MATUNER,PERFORM SETPARM TARGSYS1(*) parameter(operand)

where the asterisk is a wild card used to represents the target system names, parameter represents the parameter to be changed, and the operand is the new value.

The following example demonstrate the use of the SETPARM command to change the MAXACT parameter from its current setting to10 for all servers in the XCF group.

F MATUNER,PERFORM SETPARM TARGSYS1(*) MAXACT(10)     

To change the MAXACT value for a single server, you would identify the server using the TARSYS1 operand rather than inserting a wild card, as shown in the following example.

F MATUNER,PERFORM SETPARM TARGSYS1(SYSA) MAXACT(10) 

Using SETPARM temporarily changes the parameter value for the selected server. To permanently change the parameter value, edit TUNSSP00.

The available parameters for use with the SETPARM command are discussed next.
