For disaster recovery testing I will

1.Shutdown the primary
2.Shutdown standby and take a backup of standby
3.Put standby back in managed recovery mode and initiate procedures
to open it through a failover process
4. Do testing
5. After testing restore backup from step 2

So, when I shut down the primary can I be assured all logs will be sent to standby and applied? (No standby log files) Or do I have to go and grab the log files from the primary, take the standby out of managed recovery mode, manually apply the logs from the primary and then proceed with step 2
