ECO KIT SUMMARY:
An ECO kit exists for F11BXQP.EXE on OpenVMS VAX V6.0. This kit
addresses the following problems:
PROBLEMS ADDRESSED IN VAXF11X04_060 FOR OPENVMS VAX V6.0
o These OpenVMS VAX V6.0 problem corrections were included in the
multi-version VAXF11X03_070 remedial kit. They are now being
issued as a V6.0 only remedial kit.
There are no new problem corrections in this remedial kit
PROBLEMS ADDRESSED IN VAXF11X03_061 KIT FOR OPENVMS VAX V6.0
o After deletion of a large file, the free disk space value
reported by SHOW DEVICE can indicate that disks have more or
less free space than they actually have.
o Restore ability to use wildcard values for valid UIC owner and
group value ranges.
PROBLEMS ADDRESSED IN VAXF11X03_060 KIT FOR OPENVMS VAX V6.0
o As of V6.0 the XQP MOVEFILE primitive allows movement of
directory files, so long as no node in the cluster has data
from these files cached. Unfortunately the cluster-wide check
for this condition is broken. This results in cache
incoherency and consequently directory file corruption. Common
symptoms are:
- out of order directory listings
- duplicate directory entries for the same file
- "lost" files
- inconsistent directory listings on different nodes
- files appearing in directory listings which are not
"accessible" from the RMS level (e.g. you can't type them)
PROBLEMS ADDRESSED IN VAXF11X02_060 KIT FOR OPENVMS VAX V6.0
o Post V6.0 when the ACL on a file is modified the revision date
is not updated, hence it will not be backed up by an
incremental backup hence prospect of lost data.
PROBLEMS ADDRESSED IN VAXF11X01_060 KIT FOR OPENVMS VAX V6.0
o When a file is open with a NL mode access lock then an attempt
to access an extension header may fail because the FCB chain is
being rebuilt.
o The BACKUP utility accesses file extension headers directly,
without going through the synchronization of the primary
header. This allows the FCBs for the headers being looked at
by BACKUP to be deallocated by other processes. The results of
this are exhibited as any one of several different XQP
bugchecks. The most notable of these bugchecks are UNXSIGNAL
(accvio), NOTFCBFCB and XQPERRs.

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
review the article entitled:
[AES] How To Electronically Request ECO Kits Using Service Tools
INSTALLATION NOTES:
In order for the corrections in this kit to take effect, the system must
be rebooted. If the system is a member of a VMScluster, the entire
cluster should be rebooted.
