Increasing the Maximum Elements on Disk Size When the Terracotta Server Array Uses Permanent-Store Persistence Mode
To increase the Maximum Elements on Disk size when the Terracotta Server Array uses permanent-store persistence mode
1. Shut down all Integration Servers connected to the Terracotta Server Array.
2. On each Integration Server, open the SoftwareAG-IS-Core.xml file in a text editor. You can find the file in the following location:
Integration Server_directory /instances/instance_name/config/Caching
3. Increase the value of the maxEntriesLocalDisk parameter for the cache you want to change. The default value for each cache is 1000.
Note:  
The value for maxEntriesLocalDisk must be the same for each Integration Server in the cluster.
4. Save the files.
5. Shut down all servers in the Terracotta Server Array.
6. On each Terracotta Server Array server, open the tc-config.xml file in a text editor. You can find the tc-config.xml file in the following location:
TerracottaHome\bin
7. Locate the <servers><server><data> element in the tc-config.xml file and delete it.
Important:  
The <servers><server><data> element indicates the directory where the cache configuration and cached data reside.
8. Save the files.
9. Start all the servers in the Terracotta Server Array.
10. Start one Integration Server with the new configuration and verify that the change has taken effect. You can do so from the Settings >Caching pages in Integration Server Administrator.
11. Start the other Integration Servers.
