Overview

The caching system is optimized for use in a clustered installation, where you set up and configure a separate external cache server.

Use the same Linux package that you used to install the application servers to install a separate cache server that application servers can use in a cluster.

If your installation uses a single application node, the installation does not enable the cache services; instead, the installation uses the local cache installed within the application server. When you have a multi-node configuration, follow through this article which provides the steps in configuring the cache server in the cluster.

Process

1. Install the Jive RPM file (the same RPM file used during the Jive package installation and starting up)
2. Because the cache server machine's only function is operating as a cache server, only enable the cache service. To do this, type the following as jive user:
   

   jive enable cache

   Note: If you're logged in as root, you can use su - jive to become the jive user.

3. Configure the cache server with its address.
4. Register and start the caching service by using the following commands:
   

   jive set cache.hostnames hostname 
   jive start

   The cache service writes several log files to $JIVE_HOME/var/logs/. These are:

   • cache-service.out: Cache startup messages, output from the cache processes, showing start flags, restarts, and general errors.
   • cache-gc.log: The output from the garbage collection of the cache process.
5. If you haven't already, set up your application cluster to use the cache server address. You can find this in the Admin Console, at System > Settings > Caches.
