The Servers node displays the names of all Process Engine (PE) servers and load balancers in the farmed PE system. You can start, stop, and configure most server properties for all servers from any PE server; however, some server properties can only be configured on the local server.
To add a PE server to a farmed system, install the PE software on the server, configuring it to use the same database as the other servers in the farm. You can add a server while the other servers are running.
PE allows you to add servers to your system in order to improve performance and availability. A group of related PE servers is referred to as a farmed PE system, or simply a farm. A farm is a set of servers that share the same workflow database, each actively providing the same service, with the same applications. A farm can use one or more load balancers to distribute work between servers.
All running servers in a farmed PE system must have the same:
Since the system time in a farmed PE system is synchronized by the database, the following limitations exist:
NOTE The statistics functionality provided by vwtool, the Process Java API, and Process Administrator is not available in a farmed PE system. Instead, you can view statistics using the optional Process Analyzer capabilities.
