ECO KIT SUMMARY:
An ECO kit exists for CMA$OPEN_RTL.EXE and CMA$RTL.EXE on OpenVMS VAX V6.1
and V6.2. This kit addresses the following problems:
Problems Addressed in the VAXCMAR04_062 Kit:
o Paths to initiate time slicer for the pthread api and the exception
returning api failed to enable the time slicer.
Problems Addressed in the VAXCMAR03_062 Kit for OpenVMS VAX V6.2 ONLY:
o Prior to this change, the DECthreads time-slicer would be
operational regardless of whether any threads had actually been
created. This change delays enabling the time-slicer until the
first thread create operation. Hence products which only
occasionally use threads do not have to pay the time-slice penalty
when threads are never used. Note that once enabled, the
time-slicer stays enabled for the process until the program which is
using threads exits. This causes system performance problems for
systems which utilize a large number of ACMS processes.
Problems Addressed in VAXCMAR02_062:
o When CMA$NOCACTUSSTACK is defined, cactus stack linking is disabled.
This was done under a logical, as disabling cactus stack linking has
the unpleasant side effect of disabling the ability to use <CTRL Y>
DEBUG. There is a class of customers who require the cactus stack
linking and can't be impacted by this change, but SWIFT customers
require that we disable cactus stack linking.
Problems Addressed in the VAXCMAR01_062 Kit:
o A non-Fatal exception that is raised is not caught in V6.2. This
non-fatal exception was caught in V6.1.
Problems Addressed in the VAXCMAR01_061 Kit:
o When using the DECthreads call cma_delay or any timed condition
wait, threads may hang.

ECO KIT ORDERING INSTRUCTIONS:
If after an evaluation you wish to obtain this kit, request it
electronically using the appropriate Advanced Electronic Services
(AES) Service Tool. If you are not familiar with how to request
kits electronically, open the DIA, WIS or DSNLINK database and

INSTALLATION NOTES:
The system does not need to be rebooted after this kit is installed.
However, if you have other nodes in your OpenVMS VMScluster, they
should be rebooted or you should install this kit on each system in
order to make use of the new image(s).
