Hi Ron, Thanks for your excellent explanation. (PS: I attended one of your VSAM courses in Wellington, New Zealand, back in the early 90s).
Just to elaborate on the "lots of redundant datasets" and HLQ's... for example, we have a HLQ called "BUS", and approx 9000 BUS.* datasets of which about 95% of them have been migrated to tape. The remaining 5% which are still being used are because people have been to lazy(?) to change a few remaining jobs to use a different HLQ. We could safely change these 5% remaining jobs, and then delete all BUS.* datasets. However, seeing as this has not been done, would this have much of an overhead performance impact on the Catalog / CAS?? Could you please elaborate on this finer detail? Thanks very much. ---------------------------------------------------------------------- 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
