General Properties
UUID
The universal unique identifier assigned by the system to this data store for administrative purposes.
Information Value Required No Data type String
Data source JNDI name
The JNDI name of the data source that the messaging engine uses to access the relational database management system (RDBMS) for the data store.
Information Value Required Yes Data type Text
Schema name
The name of the database schema used to contain the tables for the data store.
Each messaging engine stores its resources, such as tables, in a single schema. Each database schema is used by one messaging engine only. Although every messaging engine uses the same table names, its relationship with the schema gives each messaging engine exclusive use of its own tables.
Information Value Required No Data type String
Authentication alias
The name of the authentication alias used by the messaging engine to access the data source.
Information Value Required No Data type drop-down list
Create tables
If this option is selected, the messaging engine creates the database tables for the data store automatically. Otherwise, the database administrator must create the database tables manually.
Information Value Required No Data type Boolean
Restrict long running locks
This option ensures that the active messaging engine does not retain long running locks on the SIBOWNER table in the database.
When this option is selected, the messaging engine establishes a lock over the database only for short durations. In the event of the active messaging engine not responding to the database, the standby messaging engine will be able to take ownership of the database because the active messaging engine holds only short duration locks.
Information Value Required No Data type Boolean Important: Although the property is selected, the property will not be effective until the database tables are upgraded using the sibDBUpgrade command for WebSphere Application Server v8.5 and later.
Number of tables for permanent objects
Number of database tables to use for storage of permanent objects.
Information Value Required No Data type Integer Range 1 through 2147483647
Number of tables for temporary objects
Number of database tables to use for storage of temporary objects.
Information Value Required No Data type Integer Range 1 through 2147483647
