Set up a IBM Optim pureQuery Runtime Java Persistence API (JPA) application to use multiple DB2® package collections.
It is possible for multiple copies of a database schema to exist. This situation might happen in a partitioned database schema where there is one database for east coast employee data and another database for west coast employee data. In this case, the two databases have the same schema. There might be two databases with two database catalogs. Or there might be only one database, in which case, the high-level qualifier of the table names (the schema name) must be different. Since the schemas are the same, there can be a single set of JPA entities that are used to access both sets of data. There are several ways to configure JPA to handle these situations.
