Considerations When Building a My webMethods Server Cluster
Consider the following information when building a My webMethods Server cluster:
*All servers in the cluster must use the same My webMethods Server database. Make sure that you use the same My webMethods Server database JDBC URL when you install each node in the cluster.
*You should install the same set of webMethods applications (such as Task Engine), My webMethods User Interfaces, and language packs on each node in the cluster.
*To build a My webMethods Server cluster, install each node in the cluster following the instructions provided in Installing Software AG Products. You must provide the following information:
*The HTTP port number for each server instance. The default value is 8585. If you install two server nodes on the same machine, you must use a different HTTP port for each node.
*The JDBC URL for the My webMethods Server database. The URL must include any additional properties needed to support database server failover.
*The URL of the Universal Messaging server or Universal Messaging cluster to use as a JMS provider. My webMethods Server nodes go in maintenance mode if you do not specify a Universal Messaging URL, or the Universal Messaging server is unavailable. If you do not specify a Universal Messaging URL during installation, you must log in as Administrator and configure the URL on the Cluster Administration page in My webMethods.
*You can start the nodes in the cluster concurrently or one after the other, depending on your needs. The first time you start each node, it performs bootstrap activities and loads shared configuration files from the My webMethods Server database. The node is automatically added to the cluster. You can also add nodes to a cluster manually, as described in Adding a Node to a Cluster.
Important:
Do not make any cluster configuration changes while you are starting cluster nodes for the first time. If you do so, you may lose the configuration of the nodes that perform self-configuration automatically when starting for the first time.
If the startup of a node completes successfully, you can open a browser window and log into My webMethods Server as system administrator to verify that the node is running correctly.
*If you are building a production cluster, perform the following steps:
*If you know you will need a network content service, set it up as described in Configuring a New Content Service.
*If you already have a load balancer or external web server set up, change the Front End URL to point there as described in Setting the Front End URL.
