Converting a stand-alone server to high availability
You can convert an IBM UrbanCode Deploy server into the first node of a high-availability cluster.
Before you begin
Each server in the cluster must run the same version of IBM UrbanCode Deploy.
Ensure that each server can connect to each other
server on the network. For example, ensure that your firewall rules allow the servers to
communicate over HTTPS and JMS.
About this task
To convert a stand-alone server to the first node in a clustered
configuration, you first move CodeStation to shared network storage, and then modify the server
settings for multi-server operation.
Procedure
Move CodeStation to a shared storage location with a fast network connection. Because each cluster server must access the same configuration files, each server must have
access to this network storage. See Relocating CodeStation.
Install a load balancer to send requests to the servers. The load balancer must be able to forward requests to the HTTP and HTTPS ports for the
servers. For more information, see the documentation for your load balancer.
Note: Do not configure a load balancer to distribute requests for the agent JMS
communication port. To ensure agent and agent relay availability, configure them for
failover.
Important: You must configure the load balancer for session persistence,
also known as session affinity.
Stop of the server.
Add the following line of code to the
install_folder/conf/server/installed.properties file:
com.urbancode.ds.UDeployServer.multiserver=true
Start the server.
On the new cluster server, click Settings > System Settings, and set the External Agent URL and the External
User URL to the URL for the load balancer.
