Tracking IBM i System Limits, Part 2

The limits tracked vary by release and DB2 Group PTF level.

How to Back Up IFS Objects on Systems With IASPs

If an IBM i system has one or more independent auxiliary storage pools (IASPs) available and a Backup, Recovery & Media Services (BRMS) control group with a *LINK backup item for ASP device *ALLAVL is used to save integrated file system (IFS) objects, a single media file will be generated. The media file will contain objects from the system ASP, user ASPs and IASPs. BRMS will produce a saved item for objects in the system ASP and user ASPs and saved items for objects on each of the IASPs. Each of the saved items refer to the same media file.

Or that you can display file system objects for a job? This has been part of the operating system for many releases (it was introduced in 5.2!), but I think it is a very little-known and seldom-used capability.
