Property	Type of	Description
	value

MONITOR_DISPLAY_LIMIT	integer	Specifies the maximum number of Cconsole
		monitor displays that can be simultaneously
		open by all Cconsole sessions monitoring the
		engine. This limit affects the Sessions, Processes
		Resident and Activities Resident monitor
		windows. The number of these windows that
		are open affects the performance of the engine.
UNIT_SESSION_RECONNECT_LIMIT	integer	During engine recovery, specifies the time (in
		milliseconds) that an engine waits for clients to
		reconnect to a session. Default value is 60000
		milliseconds (10 minutes).
UNIT_SESSION_RECONNECT_ACTION	integer	During engine recovery, specifies the action to
		take (suspend or terminate) for client sessions
		that fail to reconnect before the specified
		timeout period
		(UNIT_SESSION_RECONNECT_LIMIT).
		Default value specifies to suspend sessions that
		do not reconnect.
UNIT_SNS_RATIO	integer	Specifies the ratio of swapable to non-swapable
		processes for the process engine. Processes that
		are not marked as recoverable (either through

the process definition or by a process client calling CreateProcess) cannot be swapped out of memory by the engine. Adjust the default value only if you are having performance problems with the process engine.

Customizing Engine Database Schema

iIS provides a default database schema that it uses to create an engine database. This default schema can be used in a development environment without modification. However, for deployed applications, you can modify the database schema according to your own database requirements. Typically, you modify the schema to add table space qualifiers or other database-specific qualifiers to the CreateTable and CreateIndex statements.
