Thank you for contacting Dbvisit.
Great job on installing and configuring your Standby setup.
It is possible, but you will have to look at the size of your redelogs and number of log switches, then increase the size of the redologs on Primary.
Another possible option is, if you are using the Daemon Processes with default intervals to do the sending and applying of archived logs, you could stop it at night.
Then have a custom schedule (script) in cron to run every 30 minutes.
