Description James Sutherland CLA 2011-05-11 15:09:00 EDT 
WLS has a GridLink DataSource feature for supporting Oracle RAC.

EclipseLink has partitioning support, this should integrate with GridLink on WLS for data affinity.

Oracle also provides data affinity support in UCP DataSource as part of JDBC support, this should also be supported, and is required for GridLink support.

- Convert partitioning partition name to an index without requiring it be an integer string value.

- Change huge cache performance tests to not take so long.

- Cleaned up some code in ObjectBuilder

- Added GridLinkDataPartitioningCallback to support data affinity in GridLink

- Added PLSQL and GridLink server test targets

- Changed JPA partitioning tests to run in any database, and on WLS
