ACMS ACMSDI_A7104023 ACMS V2.3/OpenVMS Alpha V7.1 ECO Summary
|
TITLE: ACMS ACMSDI_A7104023 ACMS V2.3/OpenVMS Alpha V7.1 ECO Summary
Modification Date: 13-JUL-98
Modification Type: DOCUMENTATION: Technical
Two new problem fixes which the kit previously
contained have now been documented.
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 ACMS V2.3 on OpenVMS Alpha V7.1.
o The ACMS Desktop server at times incorrectly manages its virtual
memory. To date the problem has only been seen on Alpha 8400
machines running OpenVMS 7.1. However, the logic error is in the
ACMS Desktop code and it would seem that the problem could occur
on other machine types and operating system versions. This can,
at times, result in an access violation. At other times it
results in the generation of a message similar to the one below:
"%ACMSDI-E-INTERNAL, Internal ACMSDI RPC error
Unable to allocate virtual memory and create a server_bind_id"
When such messages are generated it causes the active client thread
to be dropped.
Solution:
This ECO adds additional cross checking of internal data
structures prior to using their pointer references. It also
corrects the way that memory is probed to determine if it
is safe to be accessed.
o Data compression, when activated, will not compress any
workspace longer than 32K bytes. ACMSDI$DCM lists these
workspaces as uncompressable even though they should have
been compressed.
Solution:
The compress program is using an unsigned 16-bit integer to keep
track of the number of bytes remaining to be compressed. Therefore
values greater than 32K appeared to be negative. The program,
thinking that there were no bytes left to compress and that no
bytes had been compressed, considered the workspace uncompressable.
A fix was applied to change the 16-bit integer to a 32-bit integer.
o The password expiration warning message is returned to the
client even though the time before expiration is not less than
the threshold setting. This can occur when the ACMS Desktop
server startup parameter file contains a value for PASSWORD_EXP
which overrides the default value.
Solution:
This ECO kit contains a correction to the PASSWORD_EXP code to
allow the parameter file setting to be effective.
o An erroneous error message regarding mailbox deletion is logged
upon server shutdown when DECNET is not active.
Solution:
This ECO kit contains a correction so the error message is not logged
when DECNET is not active.
o There is a problem if a version 2.0 or earlier SHOW_DESKTOP_USERS.EXE
is run against a V2.2 or V2.3 ACMS Desktop server. It will corrupt
the memory of the server process. There will not necessarily be an
indication of a problem at the time that the older SHOW_DESKTOP_USERS
is run. Some time later after additional system activity it will
result in a process crash. The symptom of the crash will vary
depending upon the state of the process when the corruption occurred.
Solution:
Additional checks have been added to the ACMS Desktop server to
protect its memory from the effect of a V2.0 or earlier
SHOW_DESKTOP_USERS.EXE.
If an older version of show_desktop_users is run against the ACMS
Desktop server with this ECO4 installed, the server will log a
marshalling error to the software event log. The server will ignore
the request and the older client SHOW_DESKTOP_USERS will fail to
complete.
In order to obtain a SHOW_DESKTOP_USERS report, a version that matches
the version of the ACMS Desktop server should be used.
o This ECO fixes a problem with VMS authentication on OpenVMS V7.1.
Clients were unable to sign in to ACMS unless they were ACMS agent
accounts.
This behavior occurred as result of the ACMSDI$SERVER detached
process's username switching during signin. This behavior has
been resolved with a customized authentication library.
Solution:
As a result of using the revised library the ACMSDI$SERVER account
must contain SECURITY privilege. Client accounts will not be required
to be ACMS agent accounts, however the ACMSDI$SERVER account must
be an ACMS agent account as originally required.
INSTALLATION NOTES:
The system does not need to be rebooted after this kit is installed.
However, if the system is a member of a VMScluster, the other cluster
members should be rebooted or this kit should be installed on each
system in order to make use of the new image(s).
