sorry, do you mean after a resetlog on primary
If primary database is opened with resetlogs option following an incomplete recovery, redo apply service might halt on standby database when it encounters open resetlogs command in redo. But if physical standby database’s SCN is far enough behind the primary database’s SCN, then redo apply service can interpret open resetlogs command without stopping.
Recovering Through the OPEN RESETLOGS Statement
Data Guard allows recovery on a physical standby database to continue after the primary database has been opened with the
RESETLOGSoption. When an
ALTER DATABASE OPEN RESETLOGSstatement is issued on the primary database, the incarnation of the database changes, creating a new branch of redo data.
How was recovery performed on the primary? What were the steps? Your answer depends on what was done on the primary side.
