    Oracle Error ORA-01154: database busy. Open, close, mount, and dismount not allowed now

    Oracle Error Message

    ORA-01154: database busy. Open, close, mount, and dismount not allowed now

    Reason for the Error

    Some operation is in progress that expects the opened/mounted state of this instance to remain the same.

    Solution

    Wait for the operation to complete then retry. If attempting to do a shutdown, SHUTDOWN ABORT will work. If this is a shutdown of a standby database that is operating in NO DATA LOSS mode, you must shutdown the primary database first.
