Enabled engines are available for use when provisioning clusters; disabled engines are not made available. There are two ways to enable or disable a database engine - you can:
• Right-click on the engine name in the PEM browser tree control and select Enable database engine or Disable database engine from the context menu.
• Use the Enabled slider on the database engine Properties dialog to control the state of the engine.To open the Properties dialog, right-click on the engine name and select Properties... from the context menu or highlight the engine's name and select Properties… from the Object menu.Move the Enabled slider to the Yes position to make the engine available for cluster provisioning. To disable an engine, move the slider to the No position.Please note that disabling an engine has no impact on any running clusters; it simple prevents users from creating new clusters with the engine. You can use this feature to phase out the use of older engines.To delete an engine definition, right-click on the engine name in the PEM browser tree control, and select Delete/Drop from the context menu. The PEM server will prompt you to confirm that you wish to delete the engine before the engine is deleted. Please note that you cannot remove an engine that is referenced by one or more clusters and/or backups.
