Cache Agent The Cache Agent stores cache data and is responsible for object management. A processing unit can have one only Cache Agent. Using cache clustering technology, object data is kept in memory caches, with redundant storage of each object for reliability and high availability. Cache data is shared across all the Core Engines participating in the cluster. The purpose of Cache Agents is to store and serve cache data for the cluster. The Cache Agents are used to implement the association cache and response cache functionality. The size of a cache can be unlimited or limited. Performance is best when all the data is in the cache. Use an unlimited cache only if you deploy enough Cache Agents to handle the data. Otherwise out of memory errors may occur. How to Run Cache Agent You can start the Cache Agent as follows: 1. Open a terminal window. 2. Navigate to ASG_HOME/bin directory. 3. Type the following command to start up the stand-alone Cache Agent: ./asg-engine -u asg-cache The following command starts up the Core Engine in cache enabled mode: ./asg-engine -u asg-caching-core
