Customizing the Ehcache configuration

In Chapter 2, Load Balancing and Clustering Best Practices, we learned about Ehcache replication best practices. We learned about multiple ways to configure Ehcache replication. In this section, we will learn how to provide custom Ehcache configuration to tune the cache according to the needs of the Portal solution using the following steps:

1. Stop both Liferay Portal nodes if they are running.

2. Locate the portal-impl.jar file in the node-01\liferay-portal-6.1.1-ce-ga2\ tomcat-7.0.27\webapps\ROOT\WEB-INF\lib directory of liferay-node-01. Copy the JAR file into some temporary directory.

3. Now, using the following command, extract /ehcache/liferay-single-vm.xml, /ehcache/liferay-multi-vm-clustered.xml, and /ehcache/hibernate-clustered.xml into the temporary directory:

   jar xf portal-impl.jarehcache/liferay-single-vm.xmlehcache/liferay-multi-vm-clustered.xmlehcache/hibernate-clustered.xml
   

4. The preceding command will create the ehcache directory and extract three...
