When running Adobe LiveCycle in cluster mode, it is important to verify that the cluster is configured and started successfully. LiveCycle deployment has has twoclustering layers

Application Server Clustering
LiveCycle Clustering

LiveCycle runs on J2EE stack. J2EE level clustering should be configured as mentioned in LiveCycle cluster documentation. In this article we will go through each application server and based on logs determine if the clustering is successful or not, LiveCycle Clustering is described in the article – LiveCycle Cluster Verification.

On top of J2EE clustering, LiveCycle is clustered using Gemfire Distributed Cache. In cluster deployments, it is important that all the members of a LiveCycle cluster are able to find each other so that they can keep their individual caches in synchronization with one another. LiveCycle Cluster is configured properly or not can be identified based on two key indicators. The following are the key indicators.

Adobe LiveCycle comes with pre-configured JBoss (Community Edition only) . The preconfigured JBoss has both standalone and cluster-enabled configurations. All cluster-enabled configurations are based on UDP by default. Various enterprise organizations have very restrictive network policy and don’t allow multicasting in their networks. For such organizations, TCP based clustering is recommended option. JBoss instances belonging to different subnets require TCP based clustering only. In this article, we will go through detailed instructions to configure TCP based JBoss cluster. These instructions are applicable for both preconfigured JBoss and downloaded JBoss (Version 5.1 only).

The Following are the detailed instructions for TCP Clustering:

In most Windows server environments, users want software running as Windows services that are configured to auto-start and auto-stop on Windows start and stop. So far the LiveCycle provided TCP Locator is started using startlocator.bat script on the Windows environment. There is no inbuilt mechanism to start TCP Locator as a Windows service. However, there are various free tools available for creating Windows service for Java Applications. YAJSW (Yet Another Java Service Wrapper) is one such tool that wraps a Java process and runs it as a Windows service. YAJSW is an LGPL licensed tool.
