Disable wrapping of data type objects

By default, data type objects for Array, Blob, Clob, NClob, Ref, SQLXML, and Struct, plus ParameterMetaData and ResultSetMetaData objects are wrapped with a WebLogic wrapper. You can disable wrapping which can improve performance and allow applications to use native driver objects directly. See Using Unwrapped Data Type Objects.

To disable wrapping of JDBC data type objects:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the Domain Structure tree, expand Services, then select Data Sources.
  3. On the Summary of Data Sources page, click the data source name.
  4. Select the Configuration: Connection Pool tab.
  5. Scroll down and click Advanced to show the advanced connection pool options.
  6. In Wrap Data Types, deselect the checkbox to disable wrapping.
  7. Click Save.
  8. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).

After you finish

Redeploy the data source or restart the server.
