This patch is compatible only with AIX PowerAda 5.8d1, which was released in
September 2020.  This patch can be applied to any existing installation of
AIX PowerAda 5.8d1, such as /usr/lpp/powerada5841/powerada.

This patch is NOT compatible with AIX PowerAda 5.8c (or older).


The changes in behavior delivered herein are not documented, since the only
changes were fixes to initialization and behavior across forked processes, 
all of which is below the API described in ocs_fast_heap.h.


This patch consists of an AIX compressed tar file "aixpa58d2-patch.tar.Z"
which contains the following PowerAda files:


To install, simply unpack it on top of an existing installation of AIX
PowerAda 5.8d1.

As always, we recommend that you have a backup, such as the PowerAda 5.8d1
CD-ROM or its ISO image.  Then do the following, assuming the patch is present
in /tmp:

   su -                      # get write access to your powerada installation
   cd $POWERADA/..           # e.g., /usr/lpp/powerada5841/powerada/
   mv adarte/lib/ocs_fast_heap.a  adarte/lib/ocs_fast_heap.a.bak
   zcat /tmp/aixpa58d2-patch.tar.Z | tar -xvf -

That's it.
