Data Guard - Real Time Apply

In a normal configuration Data Guard , applying changes I  turn on by command:

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE NODELAY DISCONNECT FROM SESSION;


But in this mode, standby database apply changes after switching redolog group.

In order to applying changes in real time need to use the command:

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;

and now in v$managed_standby on standby, status for MRP0 (managed recovery process) process is APPLYING_LOG
