APAR Error Description / Circumvention

-----------------------------------------------
Restoring files that are part of a complex db network, the
restore may hung if it is done from a single volume that was
created duplicating a save performed in parallell mode on
multiple drives.

CORRECTION FOR APAR MA46766 :
-----------------------------
There are two separate save networks of DB objects near each
other on the tape.  They share the same data space index, which
was not saved.  The restore seize processing for a data space
grabs that object and all of its data space indexes and performs
a unison seize, exclusive.  The two networks are colliding due
to the parallelism during save being higher than the restore
(processing coordination and ordering).  The internal seize
protocol for data space and its set of data space indexes has
been updated.

CIRCUMVENTION FOR APAR MA46766 :
--------------------------------
None.
