Database Configuration Properties Properties needed to access the engine database. These properties include:
•database type
•database name
•user name
•user password
Database Logging Settings These settings specify whether state information is logged and which history information tables are updated by the engine.
Process Engine Components A minimal engine configuration contains an engine unit component and a database service component. An engine configured for failover also contains a Governor component.
Memory Settings These settings specify the object memory heap size allocated to the various engine components (governor, database services, and engine units). Included here is also a setting to limit the number of console monitor windows that can be open at any time.
Stack Size These settings specify the memory size of each thread started for the process engine components. Default values vary for each platform. Typically, you do not need to override the default values. For information on setting stack size in an iPlanet UDS environment, refer to the discussion on FORTE_STACK_SIZE in the iPlanet UDS System Management Guide.
Process Execution Options These settings specify how an engine manages process execution. By setting these options appropriately, you can ensure that memory resources do not become overtaxed during process execution, and thereby avoid engine performance degradation or possible failure.
Engine Recovery Options These options specify the behavior of the engine during recovery from an engine failure. They determine how long an engine waits for client sessions to reconnect, and the action to take if the client sessions do not reconnect after the timeout period expires.
