WS02 MB with External Cassandra

· Database Zone

Here are steps to follow for achieving the task

[1] Download cassandra from http://cassandra.apache.org/

[2] Unzip "apache-cassandra-1.2.0-bin.tar.gz" in "C:/" drive

[3] Cassandra configuration files can be found in <CARBON_HOME>/repository/conf/etc

[4] Edit \<apache-cassandra-dir>\confcassandra.yaml

Ensure that the paths exist for
Verify storage_port and rpc_port do not conflict on your PC. (By default, Cassandra uses 7000 for storage_port and 9160 for rpc_port)
The storage_port must be identical between Cassandra nodes in a cluster (Cassandra client applications use rpc_port to connect to Cassandra)

*Things on recommended to do.
Change the default cluster_name to avoid conflicts with existing clusters.
initial_token can be left blank, but setting to 0 is recommended if you are configuring your first node.

[5] Set Memory Capacity for Cassandra


By default, Cassandra allocates memory based on the physical memory capacity of your system. From editting "<apache-cassandra-dir>\conf\cassandra-env.sh" we can set the memory capacity for cassandra

Currently we going to Cassandra test we run on smaller footprint for test drive, (Uncomment those lines)


[6] Start cassandra from <apache-cassandra-Dir>\bin>cassandra.bat


Now Work on WSO2 MB

[7] Edit "<wso2mb-Dir>\repository\conf\advancedqpid-config.xml"

Uncomment "externalCassandraServerRequired" and make it "true"


[8] Point WSO2 MB To Cassandra by editting $CARBON_HOME/repository/conf/advanced/qpid-virtualhosts.xml file to point to Cassandra server setup.
9] Start WSO2 MB \<wso2mb-dir>\bin>wso2server.bat

[10] You can see some logs in Cassandra console.
