Re: Replicate, Imbed KeyRange
The only thing that has changed is that IBM has decided not to remove KEYRANGE. IMBED and REPLICATE are still scheduled for removal (eventually).

The original plan was to remove support for processing data sets having IMBED, REPLICATE, and KEYRANGE (IRK, for short) attributes at some future point. We had a Statement of Direction to this effect. We got a lot of feedback from people who had long retention requirements and no way to identify dumped and migrated IRK data sets. We looked at it again, and decided that we would keep support for KEYRANGE, automatically remove IMBED and REPLICATE on logical RESTORE and DFSMShsm recall, and continue to plan to someday remove access method (e.g., OPEN) support for IMBED and REPLICATE. Bette's charts from the last SHARE, the wording of the IRK health check message, Steve's Hot Topics article in the current (August 2009) issue--the deadline for which, I hasten to add, preceded the decision--and other things reflect this today. We got more feedback, mostly about user catalogs with IRKsome attributes and the disruptive application outages required to convert them. We looked at it again, and decided: - To *continue* to support IRK data sets. That's those with any or all three attributes, IMBED, REPLICATE, and KEYRANGE. - To continue to plan to have DFSMSdss and DFSMShsm remove IMBED and REPLICATE attributes from data sets during logical restore and recall operations. We still want to do this because these attributes only soak up space and potentially slow access to data sets. -- John Eells z/OS Technical Marketing IBM Poughkeepsie ee...@us.ibm.com -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

No. It is still advisable to eliminate the use of these attributes. They cause inefficient use of DASD and lead to inefficient use of CPU. It sounds like there were others where were not as diligent as you. -- Tom Marchant -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
