After our disk crashed and we had to restore all our software from backups, I decided to use the user tools that were shipped with V2R1 of OS/400 to check our system for damaged objects. To my dismay, I had 24 pages of damaged objects listed (the program took about 8 hours to run). After many hours of working on getting a clean report and getting IBM Level 2 help, I discovered the answer was simple. The user tool CHKOBJDMG uses the command SAVOBJ to save the library objects to a save file. An object that has type *DOC, *FLR, *PRDLOD or *PRDDFN will not work with the command SAVOBJ because it will say it's an invalid type.

I easily changed the program TAALIBFC in source member QUSRTOOL/QATTCL to use the command SAVLIB when the object type is one of the above types, instead of SAVOBJ. Also, I added the system libraries QDOC, QRECOVERY, QRPLOBJ, QSPL, QSRV and QTEMP to the libraries that it can't check (it already skips QSYS). Now I have a clean report. 1 shows TAALIBFC with my additions highlighted.

Editor's Note: We like to test what we publish, but this contribution presented a problem. Our system has no damaged objects, and we don't know of a way to damage an object intentionally. Therefore we trust the author's word that the technique presented here works.
