SQL> from the cause of the problem, we can see that the database is interrupted because the database is closed, and the shutdown command cannot be used to close the database. Therefore, you can think of it, we can use shutdown abort to stop the current database instance when it is disabled normally or cannot work immediately. Www.2cto.com Shutdown abort has the following features: l the Oracle server immediately suspends the SQL statement being processed; l the ORACLE server does not wait for the user currently connected to the database to disconnect; l The data redo log buffer is not written to the disk; l unfinished transactions are not rolled back; l the instance is terminated, but the file is not closed; l ORACLE closes and unmounts the database; l instance recovery is required for the next startup. This is automatic.
