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.
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.
