Sun Microsystems 3 manual Process execution options are the following

Configuring an Engine

The process execution options are the following:

Process Execution	Description
Option
Maximum number of	The maximum number of concurrent sessions supported
sessions	by the engine. Attempts to open additional sessions will
	raise an exception. The default value is 300.
Maximum number of	The maximum number of concurrent process instance
processes	executions supported by the engine. Attempts to
	instantiate additional process instances will raise an
	exception. The default value is 0 (no maximum)
Memory-resident	The number of process instances retained in memory.
process limit	When the number of memory-resident process instances
	exceeds this limit, the engine swaps out dormant process
	instances, allowing for execution of newly activated
	process instances. The default value is 1000.
Swap-out interval	The time interval (in milliseconds) at which the engine
	checks the number of process instances resident in
	memory and swaps out dormant process instances. The
	default value is 10,000 milliseconds.

For information about how to use these configuration options, see “How to Tune Process Execution” on page 116.

14.Specify engine recovery behavior.

If an engine goes down, and then recovers, you can specify how long the engine waits for clients to reconnect and the behavior of the engine in the event the client does not reconnect before the timeout period.

By default, an engine waits 10 minutes (600000 milliseconds) for a client to reconnect. You can modify this value from the Options tab. If a client fails to reconnect to the engine after the timeout period, by default, the engine suspends the session. You can change the default behavior, and specify that the engine terminates the session.

15.When you have finished configuring your engine, click the Create button to create the configuration file.

The engine configuration file is saved to a standard location on the central server (see “Engine Configuration File” on page 90).
