Setting up the Terracotta Server Array for Use by the Cluster of Integration Servers
Before you enable clustering using Terracotta, perform the following steps to ensure that the Terracotta Server Array is ready for use by the Integration Servers in the cluster.
Step
Description
1
Install the Terracotta Server Array if you have not done so already. For installation instructions, see Installing Software AG Products.
Note:  
Before you install your Terracotta Server Array, you need to decide how many Terracotta Servers will make up the array and whether or not you will mirror those servers. To guide your decision, review the sections on high availability and architecture in the product documentation for the Terracotta Server Array or consult your Software AG representative.
2
Configure the tc-config.xml file on the Terracotta Server Array as described in the section on configuring the tc-config.xml file in the Ehcache chapter of webMethods Integration Server Administrator’s Guide. This section describes the parameter settings that are required when using a Terracotta Server Array with Integration Server.
3
Install your Terracotta license key on each Integration Server in the cluster. For procedures, see the section on installing and changing a Terracotta license in the Ehcache chapter of webMethods Integration Server Administrator’s Guide.
After you complete these steps, you can enable clustering as described in Enabling Clustering for an Integration Server .
