Even ardent GRS star advocates had a hard time buying this story some years ago. We had a single non-sharing system where a catalog management job ran many times longer than on any other system--even the feeble sysprog sandbox. In comparing systems, the only visible difference I could see was that this single system was still running GRS ring mode because hey, it was only a single system, why bother with star?
On a pure guess, I converted this system to star mode even though it was not sharing with anyone else. From that moment onward, the catalog job ran there as well as anywhere else. Go figure. . .

Dave, SDSF primary command syntax is a bit clunky as it has to support "the way it has always worked" and every parameter is positional rather than a more modern "keyword(value)" or "keyword=value" format. I have the ear of the current SDSF development team and perhaps they can provide something like a "ENQD dsname_pattern" command that would prime the major name with "SYSDSN", the SYSNAME with "*" and then filter the minor names by the specified pattern. Let me know if this sounds like something you would like. As for the response time of the "N" and "D" line commands, that very much sounds like something to do with your GRS configuration - perhaps raise a PMR with IBM to investigate if you believe that this is not a simple case of lack of CPU power?

Rob, I've been playing with that too. ENQC is nice, shows plex-wide enq contention, ENQ not so much, kludgy IMO. By default ENQ is single system, and to enable all systems, you have to also specify major name. So ENQ SYSDSN * to get all systems in the plex. No way to pass any kind of filter on the major name, so you get (in my case, a list of 268K entries back) all data set names. Which you can then use a filter or find commands against, but why on earth no short cut? ENQC is easy enough that my operations staff can use it to see who is holding up a production batch job. However on occasion, they want to just "look up" a dataset to see if anyone is using it at that moment. I realize there are methods via ISPF 3.4, etc, or just issue the D GRS,RES=(SYSDSN,'DATA.SET.NAME') As for the "N", I've tried that too. I don’t know if something is wrong, but when I use that, it takes a good 15 seconds for the display to come back, and then its scope is only that single system. Once that list is produced, and you issue a "D" next to the dataset to display all enqueues, another 15 seconds, and even that display is single system. _________________________________________________________________ Dave Jousma Manager Mainframe Engineering, Assistant Vice President david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Rob Scott Sent: Tuesday, November 21, 2017 9:28 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Useful little utility? **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** Check out the new "ENQ" command in SDSF (2.1+) as it supports sysplex-wide ENQ information display. Note that you can also do an "N" action in the "NP" column on the DA panel to show enqueues for the ASID only.

My wish for ISRDDN would be to be able to toggle on/off sysplex-wide ENQ data for STAR mode GRS configuration. ISRDDN ENQ pulls up a TASID-like panel, but there is no way to make it display global enqueues that I can see. All I get is a LIMITED ENQ DATA in the upper right corner, and extended help says: This system is running with SETGRS MODE=STAR. ENQ information will not be collected from other systems. As a result, ENQ displays may not reflect all of the ENQs which are known to GRS. _________________________________________________________________ Dave Jousma Manager Mainframe Engineering, Assistant Vice President david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Richards, Robert B.

I use ISRDDN enough times per day that I created a command table entry for it so that I only have to type DDN from anywhere. I just checked the new PARM command in SDSF. If you are using SYSNAME *, it will search for a member (masking acceptable) in every parmlib dataset listed. I did not see the capability to search for a string from that display, unless I missed it in my quick read of the tutorial . Still, that member search can be very powerful in its own right, especially in shops with tons of lpars.

I knew about the LINKLIST command, but had never noticed the PARMLIB command. Oh, well, another one bites the dust. -- I have a theory that it's impossible to prove anything, but I can't prove it.
