There's been some disagreement over the specification of CISIZE for the SMF datasets. A CISIZE of 26624 gives you 52K per track on a 3390 (2 CIs) ... slightly better performance. A CISIZE of 18432 will give you 54K per track on a 3390 (3 CIs) ... sightly better space utilization. Make your own choice. And, as always, YMMV.
The BUFSP parameter should typically be 5 times the CISIZE. The average (first number in) RECSZ value pretty much doesn't matter (in this case); the maximum (second number in) RECSZ value MUST be 32767. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
