Greetings and salutations, fellow IDMS'ers. I have a question to ask the group. Back in release 17, the "Feature Guide" mentioned that "Large Format Dataset" support was added, but it doesn't say for what (database files, journals offloads, log offloads, backups, ?). I've asked around and no one seems to have tried using an IDMS database dataset (BDAM) larger than 65,535 tracks ("Large Format"). When I look in the z/OS book, it says "Large Format Files are only supported for VSAM, sequential,etc., but NOT for BDAM". So I'm wondering if IDMS will only support "Large Format Files" for IDMS database files when using VSAM (only). Anyone?
Large Format is supported on database, journal, and log files. EXCP is used for random access, not BDAM. For sequential access QSAM is used.
Thanks, Lynn. Appreciate it. Usually I just add a file when I run out of space. But this time, I want to try using a "Large Format" file, and didn't want to waste time setting it up only to find out it didn't work. AWESOME! Thanks again. And for all those that I talked to about this - there is our answer! Mystery solved.
