Switch to Memcached
You can switch from the default Infinispan cache framework your own Memcached instance.
In order to complete this procedure, you must have your own pre-configured Memcached instance. You should have also installed the Analysis Enterprise Edition package to your Pentaho Server or standalone Mondrian engine.
Switch from the Infinispan cache framework
If you already use the Memcached cache framework in your organization and would like to hook it up to the Pentaho Analyzer OLAP engine, follow the directions below to switch from the default Infinispan cache framework configuration.
Perform the following steps to switch from Infinispan to Memcached:
If the Pentaho Server or standalone Mondrian engine are running, shut them down now.
Verify the required JARs are present in the /WEB-INF/lib/ directory inside of your deployed pentaho.war or Mondrian engine.
If you performed a default install of the Pentaho Analysis Enterprise Edition package, then you should have all of the required JARs installed to the Pentaho or Mondrian Server. If you are not sure, the required JARs are:
Edit the pentaho-analysis-config.xml in the /WEB-INF/classes/ directory inside the deployed pentaho.war or Mondrian engine, and change the value of
SEGMENT_CACHE_IMPLto match the class name referenced below:
Edit the memcached-config.xml in the /WEB-INF/classes/ directory inside the deployed pentaho.war or Mondrian engine, and change the values of
WEIGHTto match your preference:
<entry key="SALT">YOUR SECRET SALT VALUE HERE</entry> <entry key="SERVERS">192.168.0.1:1642,192.168.0.2:1642</entry> <entry key="WEIGHTS">1,1</entry>
Your Pentaho Analysis Enterprise Edition instance is now configured to use Memcached for OLAP segment caching.
