Careful with that assumption. You need to look way in the future. For example, some of these datasets are to be cataloged in the MCAT, this could influence your decision. Other problem is, naming standards across LPARS, SysPlexes, data centres, DRP, etc may or may not be consistent. Oh, are you going to share them in a SysPlex with the usual headaches of catalog management? Versioning of your products may be a challenge, unless you have a good naming standards to resolve that. It is no fun trying to run 2 versions of DB2 on one LPAR, but it can be done. Then there are billing issues as well as RACF, SMS, HSM, TSO, etc, issues to consider before you decide on a HLQ. Then the very most important issue to consider - Are you going to have datasets as distributed by IBM have one set of HLQ and customized (exits, custom mods, Test PTF/APAR) in another HLQ? Then you need to look at HLQ of all third party products too. What we do, some products are starting at SYS1. For example RMF, which we start with SYS1.SERB*. Assembler with SYS1.ASM.*, etc. For some, we leave the HLQ as we see/receive from CustomPac/ServerPac (SMP/E), example: Bookmanager at EOX.*/EOY.*, SDSF at ISF.*, etc. We generally have unique HLQ for things which were customized, so the 'vanilla' datasets we get from IBM and vendors remain unchanged during usage and distribution accross datacentres/rolling upgrades. I have a problem with two products with the same HLQ. RACF is my friend to resolve that conflict. Reread Radoslaw point nr 3. As others said, YMMV. I would suggest you and your team reread that Program Directory and that book IBM gave to you regarding installing z/OS from your previous level to your newly ordered level. In one of the Appendixes there are a paragraph for each product with all its distributed and target dataset names with the suggested HLQ. HTH!
