ABSTRACT OF PROBLEM
___________________
TPFDF recoup crossover processing during phase I hangs with the
online recoup and pools maintenance package (PQ42097).
COMMENTS ON PROBLEM
___________________
During phase I of recoup, if an embedded reference is found in a
traditional TPF file that describes a TPFDF file, recoup proc-
essing will "cross over" to TPFDF. TPFDF recoup processing uses
some of the same fields as TPF recoup processing, including
BK0GCR in section two of the recoup keypoint. However, the
usage of this field is not consistent. In TPF, this value
represents the number of created ECBs for that restart area, and
the difference between BK0GCR and BK0GER represents the number
of active ECBs. In TPFDF, BK0GCR represents the number of
active ECBs; there is no counter for the number of created ECBs
for that restart area. As a result, TPFDF assumes that when
BK0GCR exceeds the maximum number of available ECBs, no more
ECBs are available. Recoup defers until BK0GCR is decremented
below the maximum, even though more ECBs are available.
SOLUTION
________
TPFDF recoup processing has been changed to be consistent with
TPF recoup usage of BK0GCR. Now, BK0GCR represents the number
of created ECBs for that restart area, and instead of decre-
menting BK0GCR whenever an ECB exits, BK0GER, which represents
the number of exited ECBs for that restart area, is incremented.
