| DESCRIPTION OF ENHANCEMENTS |
This patch will resolve the following issue:
Problem:
--------
The CMOP-Nat VistA system migrated to the Region 1 Denver Data Center on
July 29, 2017. During the migration a problem was identified with the HL
Logical Link "PSU SEND". It was discovered that the HL Logical Link entry
on all VAMC VistA systems was set with an invalid DNS DOMAIN of
"CMOP-NAT.DOMAIN.EXT". The Region 1 Denver Data Center migration team along
with the National VistA Migration Team requested that a national software
patch be created and released to update the "PSU SEND" entry in the HL
Logical Link file to use the correct DNS DOMAIN "HL7.CMOP-NAT.DOMAIN.EXT".
This change is required so that when there are hardware changes to the
CMOP-Nat VistA system, VistA HL7's DNS-aware functionality will automatically
update the link's IP address without requiring individual, manual updates at
each site. During the migration as a work-around, "CMOP-NAT.DOMAIN.EXT" and
its associated IP were broadcasted nationally so there would be no disruption
to message traffic being sent by the VAMCs, but "HL7.CMOP-NAT.DOMAIN.EXT" is
the preferred and best long-term solution. The PSU SEND logical link was
created during the pre-install steps of PSU*4*3 (PBM EXTRACT ENHANCEMENT
III).
1. I16082026FY17 - PSU SEND has incorrect DNS DOMAIN
Resolution:
-----------
A post-install routine (PSO23PI) will be executed following the installation
of this patch and will perform the following update if necessary:
1. Loop through all the records in the HL LOGICAL LINK file (#870) and
retrieve the value for the DNS DOMAIN field (#.08)
2. If the DNS DOMAIN value (converted to uppercase) is different than
"CMOP-NAT.DOMAIN.EXT", skip the record (no update)
3. If the DNS DOMAIN uppercase value is equal to "CMOP-NAT.DOMAIN.EXT",
update it to "HL7.CMOP-NAT.DOMAIN.EXT"
Once the patch PSU*4*23 successfully installs a Mailman message will be sent
to the PSU MAIL group and the person who installed the patch with the
following information:
Subj: PSU*4*23 DNS DOMAIN CMOP-NAT.DOMAIN.EXT Update [#2737116]
From: POSTMASTER In 'IN' basket. Page 1 *New*
--------------------------------------------------------------------------
The post-install routine performed the following updates:
HL LOGICAL LINK DNS DOMAIN (Before Patch) DNS DOMAIN (After Patch)
--------------------- ------------------------- ------------------------
PSU SEND CMOP-NAT.DOMAIN.EXT HL7.CMOP-NAT.DOMAIN.EXT
Enter message action (in IN basket): Ignore//
In case the post-install routine does not find any entries in the HL LOGICAL
LINK file that needs to be updated it will instead send this message:
Defect Tracking System Ticket(s) & Overview:
Subj: PSU*4*23 DNS DOMAIN CMOP-NAT.DOMAIN.EXT Update [#2737114]
From: POSTMASTER In 'IN' basket. Page 1
-------------------------------------------------------------------------
The post-install routine found no records in the HL LOGICAL LINK file
(#870) with the DNS DOMAIN field (#.08) set to 'CMOP-NAT.DOMAIN.EXT'.
No updates performed.
Enter message action (in IN basket): Ignore//
--------------------------------------------
Note: Non-production accounts usually have the DNS DOMAIN field (#.08) in
HL LOGICAL LINK file (#870) set to null/blank and for this reason this
patch will make no update in most of these accounts.
