Configuring a Console Cluster

You can set up multiple machines to run the Management Console, all communicating with the same database.

Clustering management consoles scales request handling.
Important: Clustering does not provide failover capability or other high-availability capability. It is intended only to scale request handling.

When you set up a cluster of Management Consoles, you need to create a master console and any number of additional secondary consoles.

Note: If your master console uses the default DB2 database (or any database local to the master console machine), make sure the database server is configured to accept external connections via TCP.
Complete the following steps for each secondary console:
  1. Install the Management Console on a different machine from the master console. During the installation, on the Database Settings page, select a non-default database and configure it with settings that match the database used by the master console. The master console may use the default database (a DB2 Express installation local to the master console machine) or an external database, but all secondary consoles must be configured as using an external database (the master's database). If the master console does not use the default DB2 database, then the database configuration for master and secondary machines is the same.
  2. Configure database client software on the secondary console machine. For example, if you are using DB2 as your database server, install the DB2 runtime client and catalog the system database to allow the client to find it.
