Perth is home to three major vendors (Rocket, HCL and 21st Century), IBM and mainframe customers who are busy modernizing their applications and would be very interested in zCX.

Hi, in case anyone else is having failures using the old SWAREQ REXX that is floating around (originally from Gilbert Saint Flour), in our case as part of a REXX that compares catalogues via the IGGCSI00 program and various other methods, you will need to change your job class to SWA=BELOW to get it to work.

Re: [External] Re: Power failure
Jerry, That's true (it's also true if you accidentally IPL a test system using the production paging subsystem) that corrupting/losing critical DASD will cause z/OS to fall over. However, I believe the OP mentioned that the SEs were restarted as well. I don't recall if the z14 has internal battery backup for the SE's or not, but if not, IBM made (in my opinion) a mistake moving from laptops with internal batteries to 1u "pizza boxes" for the SEs without BBU. It sure smells to me like there was some kind of power issue that impacted both of the power feeds coming in to the z14.

Re: How define a cluster bigger than 4GB?
I must clarify the use of DSNTYPE=LARGE... *sound of buzzer* thanks for playing. Notes from the from the book -- please note 1) Extended format MUST BE system managed 2) DSNTYPE=LARGE does not have to be system managed.. 3) DSNTYPE=LARGE can be supplied via DATACLAS. a google search for "DSNTYPE=LARGE" should take you to this link as well https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.4.0/com.ibm.zos.v2r4.idad400/d4425.htm Cut n paste from the book Allocating an Extended-Format Data Set. Extended format data sets must be system-managed. The mechanism for requesting extended format is through the SMS data class DSNTYPE=EXT parameter and subparameters R (required) or P (preferred). The storage administrator can specify R to ensure the data set is extended. Then, for VSAM data sets the storage administrator can set the extended addressability attribute to Y to request extended addressability. Extended format can also be requested using the DSNTYPE parameter on the JCL DD statement, with values of EXTREQ (required) or EXTPREF (preferred). The DSNTYPE specified on a JCL DD statement overrides any DSNTYPE set for the data class. In addition to a DSNTYPE of EXTENDED, COMPACTION=YES in a data class definition must be specified if you want to request allocation of an extended format data set in the compressed format. A compressed data set can be created using the LIKE keyword on the DD statement and not just through a data class. Allocating a Large Format Data Set. Large format data sets are sequential data sets that can grow beyond 65 535 tracks (4369 cylinders) up to 16,777,215 tracks per volume. Large format data sets can be system-managed or not. You can allocate a large format data set using the DSNTYPE=LARGE parameter on the DD statement, dynamic allocation (SVC 99), TSO/E ALLOCATE, or the access method services ALLOCATE command. The SMS data class can also provide the DSNTYPE value of LARGE, if the data set does not have another DSNTYPE specified or a DSORG value other than PS or PSU.

Re: Pervasive Encryption questions
We are investigating. There is a caveatand what you are talking about is dataset encryption. There are other facets to "pervasive encryption" including coupling facility encryption if PS, TCPIP encryption, etc. For dataset encryption, IBM is recommending activating ZEDC compression engines, and first compressing the data to be encrypted, there by encrypting less data, reducing the overall costs of it ~5%. Without compression the cost is quite a bit higher in CPU costs - so IBM tells us. _ Dave Jousma AVP | Manager, Systems Engineering Fifth Third Bank | 1830 East Paris Ave, SE | MD RSCB2H | Grand Rapids, MI 49546 616.653.8429 | fax: 616.653.2717 -Original Message- From: IBM Mainframe Discussion List On Behalf Of Cameron Conacher Sent: Thursday, October 17, 2019 2:25 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Pervasive Encryption questions **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** Good afternoon everyone, We are actively pursuing Pervasive Encryption with our mainframe z14 machines.

It has been suggested that we could expect to see about five percent growth in CPU activity, and other folks have suggested that any CPU increase would be transparent. I will probably lean towards the five percent number, just to feel more confident. Has anyone seen an impact on SYNCSORT with ZPSAVER?

Pervasive Encryption questions
Good afternoon everyone, We are actively pursuing Pervasive Encryption with our mainframe z14 machines. My question is related to performance. If anyone out there has been down this path, do they have real world metrics to share? It has been suggested that we could expect to see about five percent growth in CPU activity, and other folks have suggested that any CPU increase would be transparent. I will probably lean towards the five percent number, just to feel more confident. Has anyone seen an impact on SYNCSORT with ZPSAVER? I fully expect to do my own before/after comparisons, and if anyone can share any bumps in the road that they experienced, that would be great. Then I can focus on the potential difficulties/challenges.

Re: Best way for a task to give up the CPU and let other tasks run?
Yes exactly, that is part of what WLM is designed to do. In the real world most shops use WLM service classes and velocity goals to control things like CPU dispatching frequency. I'm sure there exist workloads which tend to defy the controls available in WLM, but I suspect they are quite rare. In all but those rare instances, I'd be inclined to steer clear coding something in a program for the purpose of getting it re-dispatched for some resource. My nickels' worth.

Is the task one that purely uses CPU? Perhaps looping, looking at a queue for something to do, without ever waiting for anything? If so, perhaps it should issue STIMER WAIT when it detects that it has nothing to do. If, OTOH, it waits for an ECB to be posted, or an I/O to complete, or any of a number of other things, it is already relinquishing control. -- Tom Marchant -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

"I'm done for the moment if something else would like to run" That's not for the task to decide: the dispatcher, under control of WLM, decides whether you get the CPU or will be removed from it to allow another task to run.

Re: [EXT] Re: zOS 2.4 migration guide
I think we all understand, I was actually updating my software instance from a 2.2 instance to my current 2.3 instance. Documentation is still very lacking and in my PMR that I still have open since AUGUST I've stated that fact, this is very disappointing, IBM doc, especially an installation guide and user guide for all things MVS (ZOS) were easy to follow, now defining and configuring a REQUIRED product to send email notifications, defined TCP IP policy agents, and define/deploy z/OS software is deplorable. setting up the software 'INSTANCE' I define the software and where the z/osmf server is running, and my zos global zone, from there, it appears to read the zone(s) and build a configuration, ok, so what happens when I need service? do I have to use z/OSMF to order service, fixes? it's sure looking that way.

Best way for a task to give up the CPU and let other tasks run?
Does anyone happen to know the best way for a running task to give up running and let another task run?

I have been investigating this exact issue. Looking at SMF 92 records, it appears that z/OSMF opens, reads and closes the same files thousands of times. On my Dallas RDP system z/OSMF also takes about 60m EXCPs to start up. Startup is still fast - I suspect through caching magic of read only filesystems or VM read only disks it achieves somewhere between 500K-1M EXCPs per second and takes 1-2 minutes to start. (I also wonder whether EXCPs are counted differently against filesystems.) I wrote a Java program using EasySMF to count the type 92 file close records by file name.

Re: [EXT] Re: zOS 2.4 migration guide
I’m not really claiming to troubleshoot this but I wonder - based on your EXCP count comment - what JVM heap specification people (you) are running with. I wonder if it’s garbage collecting to death. (I’d also observe Liberty Profile has a generally good reputation for being lightweight and swift to start. As always, and z/OSMF Development forgive me for this comment :-) , it depends on what you run in the JVM.)

Re: [EXT] Re: zOS 2.4 migration guide
On our z14, z/OSMF takes some 60m+ EXCPs and 300 seconds of CPU time (according to SDSF) before it can even be used... (and anything that announces its availability with "...ready to run a smarter planet" just makes me cringe.) Carmen's remark about 'clear documentation' is very much on point. Like him, I've been battling with the Configuration Assistant in order to create a comms policy. Every time I find any documentation that might help me, the examples given show a z/OSMF UI that is different to mine and so the confusion starts right at the point of logging on. I suppose its because z/OSMF is still a very young bit of software and so changes between versions are much more visible. The idea that z/OSMF is intended to eventually replace SMP is quite depressing, but - disclosure - I remember I had similar difficulty taking SMP on board some aeons ago... using it is almost second nature now.
