In a single server environment, it is clear which server instance should invoke the specified timeout method on a given bean. In a multi-server clustered environment there are two possibilities.

See the developing enterprise beans for the timer service information to learn how to configure the data source (database) to be used for each server process timer service.
Note: Once the data source for the timer service is changed to point to a different database, the server process automatically attempts to create the required tables in that database on the next server start.
If the user Id associated with the start of the server process is not authorized to create database tables in the configured timer service database, then the tables must be created manually.
