Mounif, I am unable to comment on any 'increase' of the CP utilization. CPACF has been around for a very long time. Both the systems you mention have the CPACF function. You will need a no charge feature (not available for embargoed countries) for microcode to enable CPACF. The other key point to note is to check if CPACF will support all the en/decryption algorithms you want to use. If not supported by CPACF then you might need the Crypto Express feature for which there is a charge.
Parwez BTW: I have just Googled for CPACF and Crypto Express performance etc. There are lots of hits (I haven't browsed the websites) on this subject including some SHARE presentations. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
