Installing Cassandra on the new data center

The second step to adding a data center is to install Cassandra on the designated Cassandra nodes in the new data center.

Before you begin

Before you install Cassandra, ensure that you complete the steps in Setting up a shared file system.

Installing Cassandra

Use the Sterling B2B Integration installer to install Cassandra on the designated nodes. For more information, see Installing a Cassandra node.

When the installer is run, the IP addresses of the new Cassandra nodes in the new data center are added to the global.properties through the following properties:

com.ibm.mailbox.database.cassandra.host.<n+1> = <IP address of C* host 1>
com.ibm.mailbox.database.cassandra.host.<n+2> = <IP address of C* host 2>

where n is number of Cassandra nodes already installed

For example, if the existing data centers have six existing Cassandra nodes, the file has entries from com.ibm.mailbox.database.cassandra.host.1 to com.ibm.mailbox.database.cassandra.host.6 for the existing nodes. If you add three more nodes, properties from com.ibm.mailbox.database.cassandra.host.7 to com.ibm.mailbox.database.cassandra.host.9 are added to the file.
