RE: System library list

At previous companies I put a user library in the system portion *above* QSYS. This was where I would place modified versions of system commands (change default values) so that QSYS remained "virginal". Since then I have been told this ain't a good idea.

I found the comment that "The user library list is limited in length. You might have to add a library to the system library list to get around this limitation." A little hard to understand. I'm at V5R1 and the user portion of the user library list can hold up to 275 entries. I forget when IBM changed this but obviously at least a decade ago. I think that was done for JDEdwards, but I may be mis-remembering.

Richard,

Every job shares the system library list. If you have a library that must be in every job's library list then put it on the system library list.

If you have many job descriptions with library lists it can become difficult to modify every job description to add a new library. It's easier to add the library to the system library list. It could be an authority problem where someone can modify the system library list but can't modify the job descriptions.

The user library list is limited in length. You might have to add a library to the system library list to get around this limitation.

The system library list is above the user library list. Adding a library it to the system library list puts it above any other library on the user library list.

Does anyone have a good explanation of the ramifications and possibly the why's and why nots of placing user libraries in the system portion of the library list? I just signed on to a client box and noticed many user libraries in the system portion of the list. While it looked odd, I don't know enough about it to say that it's a bad (or possibly a good) practice.

Any thoughts?

Warmest Regards,

Richard Reeve
