We are investigating. There is a caveat....and what you are talking about is dataset encryption. There are other facets to "pervasive encryption" including coupling facility encryption if PS, TCPIP encryption, etc. For dataset encryption, IBM is recommending activating ZEDC compression engines, and first compressing the data to be encrypted, there by encrypting less data, reducing the overall costs of it ~5%. Without compression the cost is quite a bit higher in CPU costs - so IBM tells us.

My question is related to performance. If anyone out there has been down this path, do they have real world metrics to share? It has been suggested that we could expect to see about five percent growth in CPU activity, and other folks have suggested that any CPU increase would be transparent. I will probably lean towards the five percent number, just to feel more confident. Has anyone seen an impact on SYNCSORT with ZPSAVER? I fully expect to do my own before/after comparisons, and if anyone can share any bumps in the road that they experienced, that would be great. Then I can focus on the potential difficulties/challenges. Thanks, .......Cameron ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** This e-mail transmission contains information that is confidential and may be privileged.
