Patch-to-Patch Dependencies
===========================
Although not a dependency, MPELXQ4 or later should be installed with e
this patch to further reduce exposure to SA2216.

External Symptoms, Cause, Fix Description
=========================================
The XM copy forward array used during the checkpoint process was built
with #1000 elements. This is an insufficient number of array elements
if there are many small transactions to copy forward, so the number
of elements needs to be increased.
