Configure a master node to run in hot standby mode. Hot standby enables a secondary node
to run in parallel with the primary master server and keep an up-to-date copy of the data on the
primary server. In the event of a primary master node failure, the secondary node assumes the
responsibility of the master node. Configuring hot standby is required in order to achieve failover.
Without hot standby enabled, the IBM®
Sametime® Video Manager can run but the master node would
need to be running as well.
About this task
Perform this procedure on the master node created in the
procedure Creating
a master node in a Sametime Video
Manager Server cluster.For information about SolidDB, see
the SolidDB High Availability User Guide.
Procedure
-
Configure the primary node by completing the following steps:
-
From the directory /root/replication_scripts, run the following
script:
sh HotStandby_config.sh primary IP address of secondary
node
For example, enter the following command:
sh HotStandby_config.sh primary 2.2.2.2
-
To stop and start the SolidDB process in hot standby mode, run following script using the
variable start, stop, or restart according to what you are trying to accomplish:
sh solidDB_primary.sh start|stop|restart
For example, to stop SolidDB, enter the following command:
sh solidDB_primary.sh stop
Note: After configuring hot standby, do not use the SolidDB standalone scripts.
-
Configure the secondary node by completing the following steps:
-
From /root/replication_scripts, run the following script:
sh HotStandby_config.sh secondary IP address of primary
node
For example, enter the following command:
sh HotStandby_config.sh primary 1.1.1.1
-
To stop and start the SolidDB process in hot standby mode, run following script using the
variable start, stop, or restart according to what you are trying to accomplish:
sh solidDB_secondary.sh start|stop|restart
For example, to stop SolidDB, enter the following command:
sh solidDB_primary.sh stop
Note: After configuring hot standby, do not use the SolidDB standalone scripts.
