OpenVMS ALPBACK05_071 Alpha V7.1 Backup Utility ECO Summary
TITLE: OpenVMS ALPBACK05_071 Alpha V7.1 Backup Utility ECO Summary
Modification Date: 23-JAN-2001
Modification Type: Documentation: Non-technical corrections
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
For OpenVMS savesets, the name of the compressed saveset
file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
saveset is copied to your system, expand the compressed
saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
For PCSI files, once the PCSI file is copied to your system,
rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can
be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
file will be the PCSI installation file which can be used to install
the ECO.

ALPMOUN05_071 remedial kit. This MOUNT kit has been superseded
by ALPMOUN06_071, and that kit was superseded by ALPMOUN07_071.

ECO KIT SUMMARY:
An ECO kit exists for BACKUP on OpenVMS Alpha V7.1 through V7.1-1H2.
This kit addresses the following problems:
PROBLEMS ADDRESSED IN ALPBACK05_071 KIT
o BACKUP/BY_OWNER %BACKUP-F-BADOPTVAL when using Identifier String
An %BACKUP-F-BADOPTVAL error can occur when using an
Identifier String for a BACKUP/BY_OWNER qualifier value.
For example:
$ BACKUP SOURCE:*.*/BY_OWNER=USER TAPE:A.BCK/SAV
%BACKUP-F-BADOPTVAL, invalid callable interface option value,
argument position 7, option type = 59, option value = 2147549409
Image(s) Affected:
- [SYSEXE]BACKUP.EXE
- [SYSLIB]BACKUPSHR.EXE
Problem Analysis:
An OWNER UIC check assumes that values would be less or equal
to UIC$K_WILD_GROUP. However, Rights Identifiers typically
have values greater than UIC$K_WILD_GROUP.
For a solution, OWNER_IN_VALUE and OWNER_OUT_VALUE checks
simply determine if the [unsigned] value is greater than zero
(0) or equal to zero (0). (OWNER_OUT_VALUE checks do not
allow wildcard group or member values.) If a wildcard value is
specified for the OWNER output qualifier value, an ININVQALVAL
message is now output, instead of a BADOPTVAL. Hence, the
latest version of BACKUP is more compatible with prior versions
of BACKUP.
In addition, the BACKUP Version Identifier Strings will be
updated to reflect this fix (controlled by BACKLUPBLD.COM).
Work-arounds:
None.
o Bugfix BACKUP API compatibility with prior versions
Using OpenVMS VAX V7.1 [SSB] as the basis for API definitions,
ONLY add new definitions (since V7.1).
An obsolete reference to STRUCTURE (keyword/qualifier) was also
removed.
Image(s) Affected:
- None
Problem Analysis:
Results of incremental changes to BACKUP API definitions were
not compared to prior version definitions. Although HSM
products used their own modified version of BACKUP, in the
future they will use main-line BACKUP functions.
Work-arounds:
None.
o Backport bug fixes from V7.2R to V7.1R
The following five problems are fixed:
1. BACKUP/SINCE and /BEFORE produces unexpected results.
2. BACKUP/OWNER=FRED results in an error.
3. A process dump cannot be produced if BACKUP fails.
4. Using BACKUP/ENCRYPT in BATCH results in an
%BACKUP-F-ENCNOTSUP error.
5. The default for /BEFORE=(value) is now the same as
/SINCE=(value).
Image(s) Affected:
- [SYSEXE]BACKUP.EXE
- [SYSLIB]BACKUPSHR.EXE
- [CLD]BACKUP.CLD
Problem Analysis:
The problems occurred because:
1. A check for conflicting qualifier usage was corrected
and was deferred to API checks.
The solution was to correct a check for conflicting
qualifier usage and it was also deferred to API checks.
2. Identifier [valid] values are now assumed to be <
UIC$K_WILD_GROUP
The solution was to change a UIC validity test to pass a
user-specified value to system service(s).
3. A handler was declared which prevented signal and mechanism
information from reaching handlers external to BACKUP.
The solution was to allow a process logical name
definition to disable registering of the API handler.
4. Encryption initialization was deferred to the API
parameter checks, but the test for this initialization
status return was not removed.
The solution was to defer encryption initialization to the
API parameter checks, but not remove the test for the
initialization status return.
5. Having the default /BEFORE=(value) the same as /SINCE=
(value) is a new customer-requested feature.
The design was to specify default="TODAY" for the DCL
command line qualifier (/BEFORE).
Work-arounds:
None.
PROBLEMS ADDRESSED IN ALPBACK04_071 KIT:
o After installation of the ALPBACK03_071 remedial kit, BACKUP
commands could not be executed. Users saw the following error
message:
%CLI-F-SYNTAX, error parsing 'SNAPSHOT'
-CLI-E-ENTNF, specified entity not found in command tables
PROBLEMS ADDRESSED IN ALPBACK03_071 KIT:
o MailBox Read synchronization problem in MME_MBX_COMM
A possible system crash occurs during Host Based RAID Unbinds
with MME code enabled. A mailbox read synchronization problem
causes the crash.
This problem only occurs when a host-based RAID UNBIND command
is done while an MME-based application is running.
This problem may occur in several different code areas of the
operating system. In order to eliminate all instances of this
problem, the following remedial kits (or their supersedants)
will also need to be installed:
ALPSYSA02_071
ALPDISM01_071
ALPMOUN05_071
ALPINIT01_071
ALPMTAA01_071
PROBLEMS ADDRESSED IN ALPBACK02_071 KIT:
o A %BACKUP-F-WAITIDLEBCB error is possible when a media error is
encountered with the BACKUP utility.
PROBLEMS ADDRESSED IN ALPBACK01_071 KIT:
o Four major problems occurred:
1. Incremental restores may get an INCDELERR error message and
loop continuously when attempting to perform a directory
tree delete on a specific DIR filespec. The following text
is an example of the message syntax:
%BACKUP-E-INCDELERR, error deleting
$4$DUA1:[WINDATA.NETSCAPE.CACHE]CACHE.DIR;1
-SYSTEM-W-NOSUCHFILE, no such file
2. A possible ACCVIO (access violation) can occur when backing
up volume sets, particularly individual relative volumes.
3. A problem with the /OWNER and /BY_OWNER qualifiers occurred
with an error message such as:
BACKUP/LOG TEST.BCK/SAVE/BY_OWNER=[20,0] X.X
%BACKUP-F-BADOPTVAL, invalid callable interface option
value, argument position 7, option type = 59,
option value = 1048576
4. Since upgrading to OpenVMS V7.1 from OpenVMS V6.2, BACKUP
procedures could not be run. BACKUP fails with an ACCVIO
error PC=0000000000000000. Although the problem matches
the contents of the article listed below, workarounds
described in the article failed at the customer site.

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).
