Our shop is z/OS 1.13+CICS 4.2+DB 10 with 6 members parallel sysplexs.
SMF don't use logstream. SMF data always is writed to SYS1.MANX.
If we change the interval of SMF, we found that IXGLOGR always use CPU
following SMF interval
Please see the RMF III report below.
The F1 DSCB does contain a flag, DS1IND02, which indicates a dataset has
been opened for other-than-input. This is the flag that alerts your backup
software that the dataset needs a backup. The backup software will reset
this flag. If you run your synchronization check prior to the backup
Interesting idea but the information is needed during a file transfer so
analysing the SMF records might be a bit lengthy! I have just noticed that
ISPF 3.4 'S' line command gives you a last reference date for the DATA
component. This would be better than nothing.

Thanks, that's very helpful. Thus prompted, I now notice that IGGCSI00 has a
last backup timestamp field name (LTBACKDT), so with all these bits of
information I should be able to determine if a sync with the workstation is
necessary. Excellent stuff!
Cheers

One possibility, which is not simply by any means, is to use the SMF data
in real time, with the SMF IEFU8x exits, to trap the SMF type 15 records
(non-VSAM open for OUTPUT or UPDAT) and type 62 (VSAM cluster opened). With
the type 62, you need to test SMF62MC1 to see if the open is for
Don't know the -71, but -16 is the fixed portion of a TIOT entry. The rest of
the 255 bytes can hold pointers to UCB's.

For the extents-per-volume question it is hard to see any basis for an

two 123 is composite and 127 = 2^7 - 1 is a Mersenne prime, but this

I was in a class a long time ago and the explanation at that time was as

They can handle up to 127 extents, but any request for secondary can take up to
5 extents to satisfy it. The comment was that the developers didn't want to

John is correct.
Many scheduling products (CA Workload Automation/ESP, CA7, Jobtrac, etc)
will monitor SMF data and have a function called a dataset trigger.
If you have such a tool, then you could review if it could help in your
situation.
Otherwise, you will need to look at the SMF Exits.

What checksum are you using that is too CPU intensive?

Alan Starr's explication is persuasive. It has the right sort of
murky period flavor: a length value in doublewords kept in a byte!

There are tools to do this. Data Propagator and STRIVA come to mind. Overhead
is pretty steep.
