Typically, in a cold standby configuration, the server
shares the database and file system with a standby server. During
a disruption, the DNS routes the traffic to the standby.
About this task
A typical cold standby configuration is shown in the following
illustration. A single server is active and another server is ready
for failover.
Procedure
To convert the cold standby configuration to clustered,
follow these steps:
- Upgrade all IBM® UrbanCode Deploy servers
to the same version, if necessary.
- Start the standby server and ensure that all servers can
communicate with one another.
- Add a load balancer and point it to both servers.
- Modify the DNS to point to the load balancer. At this point,
traffic starts to be routed to the previously cold server.
Results
The converted configuration is shown in the following illustration.
