Ed, 0F4 is somewhat generic ... question that I had was if there was any analysis or comments or why the PDSE was broken. Current SMS environment, any OEM software that was used .....
The comment of a directory page of a PDSE containing member data does not really make sense. Again, there have been known issues with OEM and or other environmental issues and they must be identified to assist in resolution of this issue. Forgive me ... I'm not quite sure what you mean by larger than PDS's... Again, what is your SMS configuration, what software was (or is) being used that is or might be causing the corruption ??. As you well know, looking at dumps is not going to help unless there is an awareness of the environment.

LOL! Of course! We've had hundreds of dumps. IBM analyzed some of them and discovered that they are all virtually identical--the 0F4 is issued because the PDSE is broken. The most recent detailed analysis showed that a directory page of a PDSE contained member data. IBM cannot tell from the after-the-fact 0F4 abend how it got that way. These PDSEs are larger than the largest allowable PDS and we do parallel updates to them (something PDS simply cannot do) so there is no way to replace this function with PDS. I speculate, for a smaller PDSE, that if you can always guarantee externally serialized updates, as if the PDSE was a PDS (e.g., by using DISP=OLD), you *might* be able to avoid this problem. But, that's just a SWAG. It's not my code. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 310-338-0400 x318 [email protected] http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- 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 ----- No virus found in this message.
