Updating the new secondary standby database
Once the new secondary standby database is created, we can start the process of shipping logs to the standby database. But at this stage, it is important to note that the secondary standby database now running on kiwi703, is reliant on the archive logs that are available on the first standby database running on kiwi702. To ensure we have logs available on the first standby database, we first run the process to ship and apply logs from primary (kiwi701)(2) to the first standby (kiwi702)(3). Then once we have successfully sent and applied logs between these, we can now send logs from the first standby database running on kiwi702(4) to the secondary standby on kiwi703(5). The arrows and numbers in the image below show the order of the steps to be performed.
You should now have two standby databases, with the second standby receiving its log files from the first standby.
The next step would be to either schedule a CRON to send and apply logs to the secondary standby.
