I use aliases all the time with the spin-off SMF files, especially the monthlies.
I/we create at least ten different daily and monthly SMF data files (we feed SMF data to other areas), I noticed that some of the other areas that use the monthly files, sometimes run the same file through their software more than a few times. Turns out they forgot which GDG version number represented which monthly tape. I did that myself on occasion. It's even more of a pain when processing daily files... Monday the input is, say..., (-1), but on Tuesday it's (-2) and so. Same thing with the monthly files, especially around the end of the month. So, in our daily SMF processing cycle, every GDG that we create is also assigned a statically named alias. For example..., SMF.MONTHLY.G0011V00 is SMF.SYSTEM.DATA.JAN2008 and the same convention is used for daily files. Best thing about this method is when the base file goes away, i.e. the GDG, the alias goes away with it. It works great.

We are installing a product on a zOS system that utilises MQ to pass messages to/from a DB2 Subsystem. When we asked the client for certain MQ dataset names, they came back with SYS5.MQ.XXXX.whatever saying that the XXXX was using an ALIAS to determine which version was being used. Therefore, we wouldn't need to change the dataset names when/if we used a new version. Could anyone explain how that works or, point me to a manual that could explain it.
