Re: realtime monitoring of various storage subpools
It may be worth writing a zOS Hot Topics (https://zos-hot-topics.com) article about all the new things added to SDSF. So that the information is easy to share, and for more people to enjoy the new stuff. - KB --- Original Message --- On Sunday, August 28th, 2022 at 8:02 AM, David Crayford wrote: > > On 26 Aug 2022, at 1:31 pm, Hank Oerlemans > > 03c4d8bf55f3-dmarc-requ...@listserv.ua.edu wrote: > > > > I'm very fond of the new stuff in SDSF with z/OS 2.5 . > > > Me too.

Re: IBM Mainframe - what is it future in the era of digital transformation
Larry, I'll let others provide summaries and links, however, I'd say mainframes are definitely here to stay. IBM and its operating systems may have been around for many years, but IBM has done an excellent job of modernizing both hardware and software. When you invoke some software, whether by mouse click, enter key, or some other means, somewhere some software must run on some hardware. When milliseconds count, you cannot beat IBM z/OS technology. And, no, I am not an IBMer. However, the last production site I worked at (now a software developer for MVS/Quickref), milliseconds counted. Our management objective was response times of 0.5 seconds or less. We ran 23M transactions per day, using z/OS, CICS, Db2, MQ and did so in an average of 0.39 seconds per transaction. Response time on a web frontend that initiated that transaction might be substantially greater, but it was not the application doing the work that was slow. I am unaware of any other platform capable of giving that type of response. These were not simple applications. Most, if not all, banking, insurance, and other financial applications run on IBM z/OS. I, personally, do not believe it is going anywhere anytime soon. It is a shame that most educational institutions have abandoned teaching mainframe languages and technologies.

IBM Mainframe - what is it future in the era of digital transformation
With the cloud era started already, I am confused by the mainframe road map and how to fit it into the cloud modernization: the world still uses it extensively, but no new young generation would like to learn it as a technology as it is old. So what is the mainframe future: it will be dying or replaced by another infrastructure or it will be modernized to fit the cloud platform? Any overview or summary or links will be helpful Thanks. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

You are going to hate this but you need to look at your CICS SMF records and you may have to turn on the 99 records for a very very short time probably 3 minutes or less Sent from my iPhone No one said I could type with one thumb > On Aug 27, 2022, at 12:00, Peter wrote: > > Hello > > Good morning to all > > I am just trying to understand a strange online application(non-CICS) delay > which is happening only for a specific location but not on all region. > > > During the delay, I don't see any delay from the zOS perspective whereas > the clocking symbol or a few min of freeze is happening only within the > online application. > > From the SMF perspective, which record can tell me the reason for delay ? > As I don't get any clue in RMF or SYSLOGS > > Any pointers are much appreciated > > We are at z/OS 2.4 and are just monoplex environment. > > Peter > > -- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Online application delay
Peter, Tricky. Is it running in its own address space, or is there other work going on in the address space at the same time. If running in its own address space - TSO RMFWDM will give you near real time reasons for delays, CPU, which volids If other work in the same address space - do you get any stats out? If the address space is lightly loaded with little work - then the transaction could be delayed 10's of milliseconds and you would not notice. If another transaction is running which uses lots of CPU, or lots of IO, or does a database query (involving a lock). This would cause your transaction to be delayed. For example 1000 IOs at 1ms per IO is 1 second of wait. TSO RMFWDM is a good start to see what the address space is belong delayed for.

Online application delay
Hello Good morning to all I am just trying to understand a strange online application(non-CICS) delay which is happening only for a specific location but not on all region. During the delay, I don't see any delay from the zOS perspective whereas the clocking symbol or a few min of freeze is happening only within the online application. >From the SMF perspective, which record can tell me the reason for delay ? As I don't get any clue in RMF or SYSLOGS Any pointers are much appreciated We are at z/OS 2.4 and are just monoplex environment.
