If you are running a large CICS shop, and you have CICS TS v3 or higher, make sure you have compression of the SMF 110 records turned on. That will greatly reduce the amount of data put to the MAN files. Of course your post processors will have to be able to decompress the records. I know that MXG will do this, and I'm sure any major post processing product will be set up to do the decompression.

I've never worked in an environment that did it that way, so I won't comment. >So it forces a switch SMF between each step. >Because the MAN files are small on very active systems >(Yes - I will be fixing that), any time I can save in switching will reduce the amount of time I am buffering SMF. I'd suggest that you do fix the two above. Then 1.5 minutes won't be an issue. It's a symptom -- NOT the problem. As to size, I'd recommend 2G per and a minimum of 6. I used to work for a large CICS shop, and we were dumping every 20 minutes during the peak. But, we didn't have any issues since dumping was asynchronous. - I'm a SuperHero with neither powers, nor motivation!
