Re: ReSizing the SMF Man Files
Posted by Tom Kelman: As long as the dump process is running properly SMF just switches between the two large datasets, and the smaller dataset doesn't even get used. Reply from Ted MacNeil: Since when? In a lifetime away, we found that the smaller ones were gettin used, in order. Well, we do have 4 MAN files on our production system. We have it set up via the IEFU29 exit to submit a started task to dump the MAN file when a switch takes place. I do believe that this is the common process. I just checked the dump tasks from yesterday and they are switching between dumping MAN1 and MAN2. MAN3 and MAN4 are never getting used. SMF will always use the first empty dataset in the series. If you're using IEFU29 to submit the dump routine at the time of the switch, you'll very rarely use any but the first two datasets. That is unless you have a very, very busy SMF system.

I've never experienced that type of activity unless someone has turned on something like a DB2 trace, and I have worked at a fairly large bank. It was a bank with a lot of CICS activity, and a lot of Batch with a lot of dataset open and closes. During the peak we were eating 2G every 20 minutes for 3 hours every afternoon.

Re: ReSizing the SMF Man Files
Not only do you need to IPL (or at least restart SMF) to change the CISIZE of the MAN files, the CISIZE of all the MAN files must be the same, and the RECSIZE must be the same as the CISIZE. See pages 2-13 and 2-14 in the z/OS 1.11 version of the MVS System Management Facilities manual for this information. If you have Barry Merrill's MXG system there is a program in the sourclib named ANALSMF. If you run a typical days SMF dumped data through that, it will produce reports that will help you decide on an optimal CISIZE for the MAN files.

Re: ReSizing the SMF Man Files
Mark is of course correct. In case you need a pointer, here's the IBM reference to the restriction on changing the CISIZE for an SMF data set. It could be a bit tricky to find as CISIZE, CI size, and control interval size are all keywords to describe this concept in the manual. From z/OS System Management Facilities (SMF) topic 2.3.1.2 Using DEFINE to Create SMF Data Sets: The CI size of the first SMF data set that the system opens during an IPL will be the CI size for all SMF data sets for that IPL. If SMF encounters a data set with a different CI size, then the data set is not used, and the system displays a message on the console informing the operator of the problem. A data set that has any error does not go on the list of active data sets. If all data sets fail to be successfully opened and allocated, then 4K (4096 bytes) is chosen as the default CI size for the IPL, and SMF buffers the data. If you define a new group of SMF data sets with a different CI size, you must re-IPL to use these data sets. When you define an SMF data set, the logical record size must be 10 less than the CI size. Brian -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: ReSizing the SMF Man Files
It also states that the CISIZE must be equal to the physical record size. Selecting the SMF Data Set Control Interval: The control-interval (CI) size of SMF data sets can range from 0.5K (512 bytes) to 26K (26624 bytes) in size, with certain restrictions. The user specifies the CI size of the SMF data set and the device type when the VSAM data set is defined. Then, VSAM chooses the physical record size of the data set based on the specified CI size and the track size of the specified device type. SMF requires the CI size to equal the physical record size; otherwise, SMF cannot open the data set. Instead, SMF issues an error message to the console in addition to displaying the 'feedback' code.

Re: ReSizing the SMF Man Files
Radoslaw, What is your reasoning behind using many MAN datasets? The system only records to one dataset at a time, unlike paging datasets which are all being used. I've found that 2 large datasets and one smaller emergency dataset are sufficient. As long as the dump process is running properly SMF just switches between the two large datasets, and the smaller dataset doesn't even get used. You only need the smaller one in an emergency when something interferes with the dump processing, like an operator cancelling the task.

As long as the dump process works well and you can keep up, I don't know what advantage there would be to having (say) 10 small ones on a very active system compared to 3 or 4 big ones. The reason we have more is to give a buffer for when a problem crops up (like the DB2 team leaving on an accounting trace) or getting through the GDG enq delay that prevents dumps during nightly processing that rolls up daily data.

You only need the smaller one in an emergency when something interferes with the dump processing, like an operator cancelling the task. Well, it depends on your MAN offload policy. I like the following: All the datasets are equal in size. The more temporary SMF activity the more (not bigger) MAN datasets as a buffer for the SMF flood. SMF dump can be to slow to follow temporary SMF activity peaks - then SMF will take another and another dataset. From the other hand single offload (dump) job will not take to much time and will not block the only remaining MAN file. Many smaller MAN datasets could allow you to perform (more easily) SMF dump ad hoc (you just need to analyze fresh records). BTW: I don't like consecutive SWITCH SMF commands to make all MAN datasets DUMP REQUIRED status and then perform massive daily dump - it means than SMF records have to be collected in memory. I write about it, because I met such scenario quite frequently. It works only when SMF activity is really predicable and small. BTW: many MAN datasets could also mean 3 of them. Sized that one is usually big enough for whole day (at least day shift) processing. YMMV. Last but not least: it was obvious for me that MAN datasets are not used in parallel.

You only need the smaller one in an emergency when something interferes with the dump processing, like an operator cancelling the task. Again, since when? I've found, especially with cheap DASD, that 5 (or 6) is much safer. And, I always make them as large as possible.

Re: ReSizing the SMF Man Files
You cannot stop and start SMF, the ONLY way to change CISIZE for the MAN files is to IPL, period. That really doesn't make sense to me, but I'll take your word for it. Do you happen to know where it's documented? I couldn't find any reference. - Ted MacNEIL eamacn...@yahoo.ca -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: ReSizing the SMF Man Files
I have to agree Ted that it doesn't make a whole lot of sense, but that is nonetheless the way it works. I extracted the following from chapter 2 (title: Selecting the SMF Data Set Control Interval) of the MVS SMF Guide: The CI size of the first SMF data set that the system opens during an IPL will be the CI size for all SMF data sets for that IPL. If SMF encounters a data set with a different CI size, then the data set is not used, and the system displays a message on the console informing the operator of the problem. A data set that has any error does not go on the list of active data sets. If all data sets fail to be successfully opened and allocated, then 4K (4096 bytes) is chosen as the default CI size for the IPL, and SMF buffers the data. If you define a new group of SMF data sets with a different CI size, you must re-IPL to use these data sets. When you define an SMF data set, the logical record size must be 10 less than the CI size.

Re: ReSizing the SMF Man Files
Ted, Alan has posted the documentation you ask for, but it had already been posted in this thread, just 4 hours ago.

Re: ReSizing the SMF Man Files
Alan has posted the documentation you ask for, but it had already been posted in this thread, just 4 hours ago. I missed it; it still doesn't make sense. I did see the latter post, though. - Ted MacNEIL eamacn...@yahoo.ca -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
