From the cause of the problem, we can see that the database is due to the shutdown process is interrupted, then the shutdown command can not shut down the database, so it is conceivable that the normal shutdown and immediate shutdown is not working, we can use shutdown abort to abort the current database instance.
Shutdown Abort aborts an instance with the following characteristics:
L The Oracle server immediately aborts the SQL statement currently being processed;
L The Oracle server will not wait for the user currently connected to the database to disconnect;
L Data Redo log buffering is not written to disk;
L Unfinished transactions are not rolled back;
L instance terminates without closing the file;
• Oracle shuts down and uninstalls databases;
L The next boot requires an instance recovery, which is automatic.
