By balancing the desire to release code faster with the need for the same code to be secure, it addresses increasing demands for data privacy. But what about the database? How can databases be included in both DevOps and DevSecOps? What additional measures should be considered to achieve truly compliant database DevOps? This whitepaper provides a valuable insight.

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
data_file_directories
commitlog_directory
saved_caches_directory
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
Search for
#MAX_HEAP_SIZE="4G"
#HEAP_NEWSIZE="800M"
Currently we going to Cassandra test we run on smaller footprint for test drive, (Uncomment those lines)
MAX_HEAP_SIZE="128M"
HEAP_NEWSIZE="32M"
[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"<clustering>
<enabled>false</enabled>
<OnceInOrderSupportEnabled>false</OnceInOrderSupportEnabled>
<externalCassandraServerRequired>true</externalCassandraServerRequired>
[8] Point WSO2 MB To Cassandra by editting $CARBON_HOME/repository/conf/advanced/qpid-virtualhosts.xml file to point to Cassandra server setup.
<virtualhost>
<name>carbon</name>
<carbon>
<store>
<class>org.wso2.andes.server.store.CassandraMessageStore</class>
<username>admin</username>
<password>admin</password>
<cluster>ClusterOne</cluster>
<idGenerator>org.wso2.andes.server.cluster.coordination.TimeStampBasedMessageIdGenerator</idGenerator>
<connectionString>localhost:9160</connectionString>
</store>
...9] Start WSO2 MB \<wso2mb-dir>\bin>wso2server.bat
[10] You can see some logs in Cassandra console.
