OpenVMS ALPSYSB03_062 Alpha V6.2 SYSTEM ECO Summary
TITLE: OpenVMS ALPSYSB03_062 Alpha V6.2 SYSTEM ECO Summary
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for SYSTEM Components on OpenVMS Alpha V6.2
through V6.2-1H3. This kit addresses the following problems:
Problems Addressed in ALPSYSB03_062:
o Three problems are related to the IEEE handler on OpenVMS:
1. Adding two floating point values, which should result in
0.0 in some cases (if one of the two operands is negative),
gives a -0.0 result instead of 0.0.
2. Adding/subtracting a zero to a denormal value yields zero
instead of the denormal value.
3. A negative double float converted to a float yields
+infinity instead of -infinity.
Problems Addressed in ALPSYSB02_062:
o Installation of the ALPSYSB01_062 remedial kit on systems with
a SYSTEM_SYNCHRONIZATION_PRF.EXE image could result in the
installation failing because of regression issues with the
image on the system vs. the image in the kit. The
SYSTEM_SYNCHRONIZATION_PRF.EXE image has not shipped as part of
VMS and should not appear as part of the consolidated SYS kits.
This image as well as other images that have not previously
shipped in remedial kits have been removed from the ALPSYSB
remedial kit.
There are no new problem corrections in this kit. If you have
successfully installed the ALPSYSB01_062 remedial kit, you do
not need to install the ALPSYSB02_062 kit.
Problems Addressed in ALPSYSB01_062:
o The AUDIT server runs into an access violation in kernel mode
when it encounters an unknown security class.
Problems Addressed in ALPSYS15_062:
o A SSRVEXCEPT crash occurred early in the boot process when a
new 'fixed' image was used. The Signal Array had an ACCVIO
with the message code in the offending PC =
EXE$WRTMAILBOX+00C1C and in the operand = EXE$DELMBX+006E4.
Problems Addressed in ALPSYS13_062:
o On OpenVMS V6.2, operations involving quiet NaN values cause
the IEEE status register to get set inappropriately. A second
problem was that converting a NaN float or double value to a
long integer causes an integer overflow exception.
Problems Addressed in ALPSYS08_062:
o A DOUBLDEALO BUGCHECK during process rundown, caused by double
deallocation of a memory block.
There is a small window of opportunity between the time the ORB
is deallocate and the time its address is cleared in the UNC
that the image could be interrupted and a rundown thread could
pick up the ORB address and try to deallocate it again.
Problems Addressed in ALPSYS04_062:
o The system hangs with a process in RWPAG while auditing an
event.
Problems Addressed in ALPSYS02_062:
o SYS$ENQ System Service call/program hangs due to the event flag
not being set.
o Due to an image build problem, the LOCKING.EXE image included
in the ALPSYS01_062 kit did not contain the problem fix it
should have.
Problems Addressed in ALPSYS01_062:
o Under certain conditions, a fork lock used by the virtual I/O
cache may be created with an incorrect length. This results in
unsynchronized data access which can cause corruption.
INSTALLATION NOTES:
The images in this kit will not take effect until the system is
rebooted.
If you have other nodes in your VMS cluster, they must also be
rebooted in order to make use of the new images. If it is not
possible or convenient to reboot the entire cluster at this time, a
rolling re-boot may be performed.
