When creating a GridLink data source in Oracle WebLogic Server, you may receive an activation error.

An error occurred during activation of changes, please see the log for details.

[Deployer:149189]An attempt was made to execute the "activate" operation on an application named "mydatasource" that is not currently available. The application may have been created after non-dynamic configuration changes were activated. If so, the operation cannot be performed until the server is restarted so that the application will be available.


  1. Create the data source normally, but do not target it to a managed server or clustered (keep it untargeted).
  2. Save and activate changes.
  3. Go back and target the data source to a managed server or cluster.
  4. Save and activate changes.
