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 ...
