Configuring an Engine
Chapter 4 Managing Engines 93
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.
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.
