If you have provisioned DB Homes with a Database Software Image (DSI), then enabling Data Guard operations will default to the same DSI as the primary DB Home.

With this enhancement.

• You can change the automatically selected primary DSI to a different DSI for the standby database.
• If the DSI used to create the primary database is not available, then enabling Data Guard will use the latest Oracle-published image. Optionally, you can configure the standby database to have a DSI of your choice.

In both cases, the system will warn you of potential issues with having different images for the primary and standby databases.
