Warning: ORA-16826: apply service state is inconsistent with the DelayMins property

Today when I tested dataguard configuration I saw ORA-16826 error.

DGMGRL> show configuration;

This is because I managed my standby database with NODELAY option.

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE  THROUGH ALL SWITCHOVER DISCONNECT  NODELAY;

To fix this cancel recover managed:

SQL> alter database recover managed standby database cancel;

Database altered.

Start with current logfile option:

SQL> alter database recover managed standby database using current logfile disconnect;

Database altered.

Try again
