This is still a documented restriction. See section 2.4.1 in the 1.9 version of the manual DFSMS Managing Catalogs (SC26-7409-05) where it states:
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2C150/2.4.1?SHELF=DGT2BK71&DT=20060608131553 The master catalog for a system contains entries for all the user catalogs that are used on the system and the aliases pointing to them. Other data sets that you should catalog in the master catalog are shown in Table 3. Table 3. Master Catalog Entries Entry types Description/Example User catalogs Entries for all user catalogs used on the system. Aliases Entries for all aliases pointing to the user catalogs on the system. Pagespaces Entries for the pagespaces used on the system. System software target libraries The data sets used to run the system such as LINKLIB and ISPPENU. Key operational data sets Key operational data sets such as: ° PARMLIB data sets ° Parameter libraries for JES and TCP/IP ° SMS configuration data sets ° SMF data sets ° RACF databases ° Couple data sets Subsystem data sets Subsystem data sets, such as those for IMS(TM), DB2®, or CICS®, especially when they are replaced. Requirement: Data sets required during the IPL process must be cataloged in the master catalog. Recommendation: A master catalog should not contain entries for application or end user data sets. These should be contained in user catalogs that are pointed to by the appropriate aliases in the master catalog. For a further description of what may occur see apar OA18992. You may get away with this at times, but sooner or later it will catch up with you. Most likely, it will catch up with you when it's most inconvenient.

I could not locate any text that even remotely resembled these statements. I do remember this being documented in "Managing Catalogs" for OS/390 2.?, because I found it when the above message was sent, but unfortunately I do not remember the exact text, so I was unable to search current versions of this publication for the old text or find the section it was once contained in. Is this still "documented?" If not, why was it removed? I hope it is because this issue has now been addressed and fixed, and the Catalog Address Space is now "full function" by the time any other address spaces (other than the ones that the Master Scheduler itself starts, of course) that start under the Master Subsystem actually do start to go through JCL conversion and interpretation, and then allocation (which is the first time that a user catalog might be referenced during IPL). Inquiring minds (still) want to know where Mark Thomen is when we really need him. -- WB ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
