Re: Do any of you have a policy on rebuilding indexes?

Hello Jim,

Part of the reason that helped, was it by definition rebuilt all the access paths in the library (or system). The system is smart enough to restore access paths such that they will share each other as much as possible, so it cuts down on the index maintenance as well as saving space. Access paths were laid down widest to narrowest to allow the system to share them. Smart system.

Your comment raises more question than it answers for me. :-)

What is the difference between an access path and an index? As far as I've understood, it's the same. Index is often used in an SQL context, while Access Path is more AS/400'ish.

Restoring access paths is dependent if you have set ACCPTH(*YES) on save. If you didn't, the system creates them anew after restore. From your description I assume you're talking about ACCPTH(*YES) on save?

You claim the system behaves differently on index sharing after a restore vs. at index creation time. May I ask for more details?
