If Integration Server cannot connect to the distributed cache at the time the Integration Server initializes, Integration Server logs an error to the server log and takes the action associated with the selected option for the Action on Startup Error parameter. To enable clustering, diagnose and correct the problem. For more information about the Action on Startup Error parameter, see About Action on Startup Error Options.

If Integration Server becomes disconnected from the distributed cache after initialization completes, the rejoin behavior instructs the system cache managers on the Integration Server to reconnect to the Terracotta Server Array automatically. All system cache managers are configured to rejoin. For more information about the rejoin behavior for distributed cache managers, see webMethods Integration Server Administrator’s Guide.
