At IPL time, the CAS is not initialized and user catalogs can not be searched. So data sets needed during IPL must either be catalogued in the master cat or accessed by explicit volume serial.
But in the case that impacted me many years ago, I wanted both the alias and the related DSN in different user cats. I didn't need either during IPL (not my job) and in user cats they couldn't be accessed during IPL. It still disconcerts me that after CAS initialization a user cat can't be searched for the alias and the HLQ of that alias could not identify a possibly different user cat to search for the related DSN. (Ih another case I would have found it useful to have an alias of an alias. That, also, should be supported.) --gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
