ECO KIT SUMMARY:
An ECO kit exists for LAT on OpenVMS Alpha V6.2 through V6.2-1H3.
This kit addresses the following problems:
PROBLEMS ADDRESSED IN ALPLAT03_062:
o VCRP packets are being overwritten.
o A CREATE LINE LINK$NAME/DEV=XXA0: command in LATCP can crash
the system.
o After executing the following commands:
LATCP> CREATE SERVICE SERVICE1/APPL
LATCP> CREATE SERVICE SERVICE2/APPL
LATCP> CREATE SERVICE SERVICE3/APPL
LATCP> DELETE SERVICE SERVICE2
LATCP> SET SERVICE SERVICE3/STATIC_RATING=1
the static ratings for services following SERVICE2 can not be
changed.
PROBLEMS ADDRESSED IN ALPLAT02_062:
o Item list verification routines caused an ACCVIO
o LATACP crashes with PGFIPLHI
o LTDRIVER crashes with INVEXCEPTN
o Some applications use break through the system service to write
to their numerous terminals at the same time. When LATCP is
running, the management LTA device created by LATCP is also
broadcast to. This slows done the application to the point
where the application exhausts its byte limit.
o An MC LATCP CREATE PORT command with an invalid device name
will crash the system.
PROBLEMS ADDRESSED IN ALPLAT01_062:
o Fix possible CPUSPINWAIT crashes and another crash during LAT
$QIO postprocessing.
o System can only sustain about 125 LAT X sessions to various VXT
2000s on the network. Some customers have more than 125 VXT
2000s and not all users can connect to larger OpenVMS systems.
o If LTDRIVER times out a virtual circuit, it will build and
transmit a LAT Stop message. If a session on the virtual
circuit attempts to write data while the datalink layer owns
the Stop message (i.e. the message is on the "to be
transmitted" queue), the system will crash in routine
LT$DECLARE_CIRC_EVENT.
o If the terminal class driver calls LTDRIVER at the flow change
entry point (typically done for a SET TERMINAL command),
LTDRIVER will remember it must change the terminal server port
settings if no LAT connection exists. Unfortunately, this is
not a desired side affect for dedicated ports and limited
ports. Note, this will only be seen if a user connects to
OpenVMS from a terminal server port that has REMOTE
MODIFICATION enabled and if they happen to get the LTA device
with this setting.
o Deleting a link already marked for deletion, or a link that is
not ready will result in a system crash.

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.
