The XMINET_ALPHA.COM command procedure is included below, and can be copied
& pasted into a VMS file directly from this message. Alternatively, the
FROM: National AXP/VMS Technical Support Team
XMINET_ALPHA.COM (XM7_1P165.COM) file will be available for downloading from
the [.SOFTWARE] directories at the following ftp sites:
Hines 152.129.1.110
Albany 152.127.1.5
Salt Lake City 152.131.2.1
To install:
Disable the UCX XMINETMM service
RE: AXP ALERT*117 HLSEVEN and XMINETMM "Openfail errors"
$ UCX DISABLE SERVICE XMINETMM (UCX Version 4.2)
or
$ TCPIP DISABLE SERVICE XMINETMM (TCPIP Version 5.0A)
Using either method, place this new XMINET_ALPHA.COM procedure in the
SYS$LOGIN directory of the XMINETMM user. Be sure to edit accordingly.
Copy and Paste Method:
$ SET DEFAULT USER$:[XMINETMM] or equivalent of the XMINETMM user.
Copy file from below into your Windows buffer by highlighting the entire
text of the XMINET_ALPHA.COM file below.
$ CREATE XMINET_ALPHA.COM
Paste the contents of your windows buffer and use CTRL Z to close file.
Then check/edit XMINET_ALPHA.COM to ensure that the DSM command line is
correct for your system. (You may use your previous version of
XMINET_ALPHA.COM file as a reference. The entry SOC^XMRUCX is correct.
HLSEVEN has uncovered a VMS TCP/IP problem regarding DSM not being able to

$ COPY XMINET_ALPHA.COM USER$:[XMINETMM] or equivalent of the XMINETMM user.
Before enabling the XMINETMM service, be sure to check the file ownership
and protection.
Enable the UCX XMINETMM service
$ UCX ENABLE SERVICE XMINETMM (UCX Version 4.2)
running VMS 6.2-1H3 to VMS 7.2.1 and also UCX version 4.2 ECO 3 as well as
or
$ TCPIP ENABLE SERVICE XMINETMM (TCPIP Version 5.0A)
Please note that Mailman puts a leading space before the "$" of each DCL
command line in the XMINET_ALPHA.COM file as it is documented. If you choose
to cut and paste the file from this message, you will need to edit it to
remove the spaces before enabling the services.

by the HLSEVEN service. These tests were run on the FORUM system and have
produced retries during heavy activity periods. Therefore, the AXP, HLSEVEN
and Mailman teams have agreed to jointly release the following Alert and
Informational patches.
AXP Alert*117
HL*1.6*70
XM*7.1*165
XMINET_ALPHA.COM file.
The following is an excerpt from Compaq Engineering acknowledging our
findings and their description of the problem.
********************************************************************
Compaq
Engineering thinks the problem here is a race between the INETACP, which
has just created the process via $CREPRC(), and the process just created.
The INETACP doesn't relinquish its ownership of the BG device for the
accepted connection (which it passes in SYS$NET process logical) until
sometime after $CREPRC() returns success status. If the process gets to
run first it may have trouble assigning this BG momentarily.
This situation only occurs for listen services; nolisten services
(like FTP) are handled very differently.
*********************************************************************
Although this problem has been acknowledged, Compaq is reluctant to issue a
Patch XM*7.1*165
patch to the current version of TCPIP V5.0 due to its complexity. They have
agreed to provide a fix in a future release. This future release should be
TCPIP Services for VMS version 5.1, due sometime next year (2001). As an
interim "work-around" solution, new HLSEVEN.COM and XMINET_ALPHA.COM command
procedures have been written to compensate for this "race condition".
XMINET_ALPHA.COM Descriptions
This command procedure has been edited to check the status of the BG device
prior to entering DSM. It contains two IF-THEN-ELSE statements. The first
is a loop to count to 10. The command procedure will terminate after 10
tries to gain access to the BG device. The second is a loop to test the bit
mask status [stat=f$getdvi("''x'","STS")] of the BG device. It was found
that with a bit mask value of 65552, DSM could not open the BG device but a
bit mask value of 16 allowed DSM to open the BG device. If the bit mask
value is not equal to 16, then the command procedures will wait one second
and try again.
Typical log file entries:
NOIS: none
Note - New log files will not be generated if the XMINET_ALPHA.LOG file
version number has reached 32767. To generate new log files, delete all
XMINET_ALPHA.LOG files and new ones will be generated starting with version
1. Please also note that empty log files may be normal. If the current log
file for the latest connection is still open and the connection is still
active, the file will be empty and nothing will be displayed. Very busy
XMINETMM services may see this and they can also generate failure to purge
error messages. Keeping more log files in the purge statement in the
command procedures can avoid purge error messages - adjust accordingly.
