Issue/Introduction
We recently upgraded our Test environment to 21.2.6 in preparation for our Production upgrade.
There are missing data in the "MapUpdate -v" output.

21.2.6.0.30 01/28/2022 10:53
Environment
Release : 21.2
Component : Spectrum Core / SpectroSERVER
Cause
There is an incorrect hostname in two configuration files.
1) $SPECROOT/LS/.locr file on the server2 (Secondary SS/OC):
LOC_SERVER_SOCKET_NUMBER=0xdaff
MAIN_LOCATION_SOCKET_NUMBER=0xdaff
MAIN_LOCATION_HOST_NAME=server2 <==== Must be server1
MAX_CONNECTIONS=750
orb_args=-Dvbroker.se.iiop_tp.scm.ssl.listener.port=14014 -Dvbroker.se.iiop_tp.scm.iiop_tp.listener.port=14004 -ORBpropStorage ../.corbarc
2) $SPECROOT/tomcat/webapps/spectrum/META-INF/context.xml file on the server2 (Secondary SS/OC):
locServerName="server2" <==== Must be server1
This issue was introduced when the same Host Installation Information (HII - hostargs) file that was originally used to install Spectrum 10.4.2 as a standalone SpectroSERVER was also used in the upgrade to 21.2.6
When Spectrum 10.4.2 was installed, the main_loc_serv value was server2 (the server hostname).
But when the Fault Tolerance was established, the MAIN_LOCATION_HOST_NAME was changed to server1, which is the primary MLS hostname. And server2 became the secondary MLS.
|
main_loc_serv=<
location server
> |
The hostname of the Main Location Server (required for all-non patch installations). You can only specify a remote hostname if you are installing a
SpectroSERVER
.Note:
Do not enter an IP address in place of a hostname. |
To avoid such issues in the production environment, the Host Installation Information (HII - hostargs) file should be updated to refer to the current MLS hostname.
main_loc_serv=server1
Resolution
1. Edit the $SPECROOT/LS/.locr file on the server2 (Secondary SS/OC):
2. Change the following line/row:
From: MAIN_LOCATION_HOST_NAME=server2
To: MAIN_LOCATION_HOST_NAME=server1
3. Save the change.
4. Edit the $SPECROOT/tomcat/webapps/spectrum/META-INF/context.xml file on the server2 (Secondary SS/OC):
From: locServerName="server2"
To: locServerName="server1"
4. Either kill the LocServer (processd will launch a new one) or stop the SpectroSERVER and processd and then start them back. Wait a couple of minutes for Locserver to talk to each other.
5. Stop/start the Spectrum Tomcat service to put the context.xml file change in place.
