Hello Erman,

I checked the document for dr test.

When you defer archivelog on the primary database, then start replication on standby, can there be any possibility of data loss?

After you defer the primary log archive destination and open the standby database, this means both primary and standby are open? Normally primary should be open and standby can mounted or readonly.

Suppose I created the checkpoint on standby at 10 am and then opened the database. Then at 11 am I did the fail/switchback. Will there be data loss from 10 am to 11 am? I assume the old primary will have the updated data from 10 am to 11 am.

Regards,

Roshan
