• The Ingres JDBC driver supports the Java 2 Platform Standard Edition 5.0 (J2SE 5.0) specification, excluding RowSets.

• The JDBC cursor default is changed to CURSOR=READONLY. This cursor mode setting typically generates improved JDBC performance, especially for selects returning many rows. A configuration parameter lets you retain the old default, if preferred.

• The JDBC ParameterMetaData interface, which is related to the DESCRIBE INPUT functionality in the DBMS, is supported. 

• Enhanced support is provided for XA transactions in J2EE environments using the IngresXADataSource.
