ECO KIT SUMMARY:
An ECO (patch) kit exists for DECmessageQ for OpenVMS VAX V2.0.
This kit addresses the following problems in addition to those already
addressed in ECO 1.
o Corrected a problem with sending a message to queue
999 generating PAMS__BADPARAM
o More than 100 Avail/Unavail registrations for a remote
group causes SBS Server crash
o Corrects five problems with the MRS Server:
1) Dynamic expansion of internal data structures
could cause a server crash
2) Increased number of open SAF files to 255
3) SAF_FILES quota now will limit total number of
SAF files
4) TARGET_PRESENTATION is now uniformly applied
5) Loss of FIFO when target queue is full
o Corrects three problems:
1) Avail/Unavail services causes initialization to
enter an endless loop
2) COM Server logging "Duplicate Queue Notification"
events
3) LIST_ALL_Q_RESP message does not return tag number
o Corrected problem with redelivery of unconfirmed
recoverable messages to an MRQ after a client abort.
o Corrected a problem with some cross-group messages
remaining in the DQF and are not removed until MRS is
restarted. Also, corrected a problem with data
structure expansion in the MRS Server.
o Corrected a problem with the SBS Server generating false
sequence gap notification events.
o Corrected a problem with the MRS Server where memory
writes occurred beyond an array boundary. Also,
corrected a problem with the MRS Server attempting to
send the same message twice to an MRQ.
o Corrected a problem with buffer pool free counts
exceeding total buffer counts.
o Corrected a problem with the SBS Server not handling
soft controller errors from optimized Ethernet
broadcasting.
o Corrected a problem with losing PAMS timers with
negative timer ID's. This caused the MRS Server to
lose it's retry timer.
o Corrected two problems with the COM Server's switching
DECnet connections. The first logs "Detected out of
order write QIO completion" messages and the second,
the prior link's DECnet I/O channels are not freed.
o Corrected a problem with the handling of negative
sequence numbers that were passed to the MRS Server by
PAMS_CONFIRM_MSG. Prior to this correction, a message
sequence number with the sign bit on in the high order
longword could cause the MRS Server to either abort
with an access violation or to loop indefinitely.
INSTALLATION NOTES:
You should shutdown all DECmessageQ groups using DECmessageQ for VMS
Version 2.0 prior to the ECO kit installation.
