Thanks a lot Mike for the additional information. This looks like something I will take a shot at.

If OPERATOR does it, you may want to place those "special commands" on OPERATOR 192 or some other disk that the OPERATOR userid cannot LINK R/W. 3) Performance command changes before/after are good to see on the OPERATOR console log. I placed all ours in a single command called "PERFCMDS EXEC" (actually, "PERFCMDS VMOPER", since OPERATOR runs them after VM:Operator has its own console log started). PERFCMDS provides documentation on OPERATOR of what the setting was before, and of the actual command. Here's a cut/paste, modified (but not tested) to run on OPERATOR (change as needed to run from elsewhere): ---<snip>--- /* PERFCMDS EXEC */ /* set recommended performance metrics for zLinux */ /* Call PerfCmd 'command , settings' */ /* (the 'command' part is used by CP QUERY and CP SET, 'settings' only by CP SET) */ Call PerfCmd 'SRM STORBUF , 300 250 200' Call PerfCmd 'SRM LDBUF , 100 100 100' /* set Delay for Linux Guest Shutdown */ Call PerfCmd 'SIGNAL SHUTDOWN , 180' /* Allow Linux Guests 3 mins to shutdown*/ Call PerfCmd 'MDC , STOR 0M 256M' Call PerfCmd 'MDC , XSTOR 0M 0M' /* Will cause repeat QUERY MDC */ Exit rc PerfCmd: parse arg cmd ',' settings parse var cmd w1 w2 w3 . say 'CP QUERY' cmd /* Document "before" setting */ 'CP QUERY' cmd say 'CP SET ' cmd settings 'CP SET ' cmd settings trace o Return ---<snip>--- Mike Walter Hewitt Associates Any opinions expressed herein are mine alone and do not necessarily represent the opinions or policies of Hewitt Associates. "Martin, Terry R. (CMS/CTR) (CTR)" <[EMAIL PROTECTED]> Sent by: "The IBM z/VM Operating System" <IBMVM@LISTSERV.UARK.EDU> 10/02/2008 02:33 PM Please respond to "The IBM z/VM Operating System" <IBMVM@LISTSERV.UARK.EDU> To IBMVM@LISTSERV.UARK.EDU cc Subject AUTOLOG Hi I am setting some parameters in my AUTOLOG2 PROFILE EXEC, but they do not seem to be taking affect. Is there something else I am missing? The ?CP XAUTLOG xxxxxxx? seems to be working fine but commands such as the following do not take affect: /* set recommended performance metrics for zLinux */ 'CP SET SRM STORBUF 300 250 200' 'CP SET LDBUF 100 100 100' /* set Delay for Linux Guest Shutdown */ 'CP SET SIGNAL SHUTDOWN 180' /* Allow Linux Guests 3 mins to shutdown*/ 'CP SET MDC STOR 0M 256M' 'CP SET MDC XSTOR 0M 0M' To test these I issue the xautolog autolog2 command from MAINT after I have LINKED to AUTOLOG2.
