I also had this PTF. SF26854 for V3R1M0.  APAR SA47856.

If I recall, they reluctantly came out with this for CISC machines.  I
believe their thinking was (and maybe still is) that the RISC processors
have the horsepower to keep these system wide database cross-reference
files in sync without adversely affecting performance.
Tell that to a development shop that restores libraries several times a
day.   I'd still like to see the ability to disable these jobs, with the
ability to start them later if you chose and have them rebuild.  (Well,
the rebuild ability is already there, but not - as far as I know - the
ability to turn it off).

        I remember getting a test PTF from IBM's database group on V3R1
for this
        very problem.  I can't remember the PTF number, but you're
right, it can be
        done.
