Description: A plugin string (see Section 4, “ Plugin Configuration ”) describing the org.apache.openjpa.meta.MetaDataFactory to use to store and retrieve object-relational mapping information for your persistent classes. See Section 5, “ Mapping Factory ” for details.

Property name: openjpa.jdbc.ResultSetType

Configuration API: org.apache.openjpa.jdbc.conf.JDBCConfiguration.getResultSetType

Resource adaptor config-property: ResultSetType

Default: forward-only

Possible values: forward-only , scroll-sensitive, scroll-insensitive

Description: The JDBC result set type to use when fetching result lists. This property can also be varied at runtime. See Section 10, “ Large Result Sets ” for details.

Property name: openjpa.jdbc.Schema

Resource adaptor config-property: SchemaFactory

Default: dynamic

Possible values: dynamic, native, file, table, others

Description: A plugin string (see Section 4, “ Plugin Configuration ”) describing the org.apache.openjpa.jdbc.schema.SchemaFactory to use to store and retrieve information about the database schema. See Section 12.2, “ Schema Factory ” for details.
