Time for action – making a physical standby database environment ready for conversion

   Database altered.

2. In order to prepare the primary database for possible switchovers with the logical standby in future, we will make some changes on the archival initialization parameters. This step is optional and if you don't plan any switchovers between the primary and logical standby in the future, you can skip this step. Run the following statements on the primary database to change the parameters:
