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

Yes, they are largely DDS based PF and LF. Some of it is an old Lansa
application, but some of it is SQL defined tables and indexes. The files
they were complaining about were in fact LF's with MAINT(*IMMED) and
REUSEDLT(*YES). We verified that.

Mark,

If they are using old legacy applications with DDS-based PFs and LFs,
check whether MAINT(*DLY or *REBLD) is specified for any keyed PFs or

LFs,

versus MAINT(*IMMED).

In the old days, people would tolerate not immediately updating the

access

paths, to speed batch update processes; then, upon a subsequent open of
those files, the access paths would get rebuilt.

This could cause the appearance of "intermittent" delays.

Just saying ...

New info, the slowness was temporary, and not happening any more. They
just have someone there who believes that index rebuilds should be normal
maintenance for any database :)
