![]() ![]() Wait until System Halted is displayed on the console.Power must be removed and reapplied for the system to restart. Warning: executing this command will leave the system in a shutdown state. Issue the command: request shutdown system.Wait a few minutes for the shut down process to complete.Click on shutdown device under device operations.Click on Device tab > Setup link > Operations tab.There are two ways to perform a graceful shut down. Note: Any configuration changes that have not been saved or committed will be lost. Disk drives are cleanly unmounted and the device powered off.If this log entry cannot be written, a warning will appear and the system will not shutdown. System Logs are created to show the administrator name who initiated the shutdown.Existing sessions are closed and logged out.During a graceful shut down, the device performs the following tasks: On the other hand, if the current database is a CDB, the SHUTDOWN statement will close the CDB instance.Since PAN-OS 5.0, the option to gracefully shut down a device is supported. The SHUTDOWN ABORT proceeds with the fastest possible shutdown of the database. For example, if you know a power shutdown is going to happen in a minute or you experience some problems when starting up a database instance. The consolidated instance will continue to run. It is recommended to use the SHUTDOWN ABORT only when you want to shut down the database instantaneously. If the current database is a pluggable database, the SHUTDOWN statement will close the pluggable database only. ![]() To issue the SHUTDOWN statement, you must connect to the database as SYSDBA, SYSOPER, SYSBACKUP, or SYSDG. The following table illustrates the differences between the shutdown modes: Shutdown Modes Unlike the SHUTDOWN ABORT option, the SHUTDOWN IMMEDIATE option does not require an instance recovery on the next database startup. The statement will also close and dismount the database. The SHUTDOWN IMMEDIATE does not wait for the current users to disconnect from the database or current transactions to complete.ĭuring the SHUTDOWN IMMEDIATE, all the connected sessions are disconnected immediately, all uncommitted transactions are rolled back, and the database completely shuts down.Īfter issuing the SHUTDOWN IMMEDIATE statement, the database will not accept any new connection. The SHUTDOWN IMMEDIATE is the most common and practical way to shut down the Oracle database. However, it requires instance recovery on the next database startup. It is recommended to use the SHUTDOWN ABORT only when you want to shut down the database instantaneously. If you try to do so, you may not be able to recover the backup. Therefore, you should never use the SHUTDOWN ABORT command before backing up the database. The database will be in an inconsistent state. The SHUTDOWN ABORT has a similar effect as you unplug the power of the server. The SHUTDOWN ABORT is not recommended and only used on some occasions. This option is useful in some cases e.g., a scheduled outage maintenance. The optional LOCAL mode waits for only local transactions to complete, not all the transactions. The SHUTDOWN TRANSACTIONAL does not require any instance recovery procedure on the next database startup. When completing all transactions, the database instance disconnects all the currently connected users from the database and shuts down. The database instance also does not accept any new transaction after a SHUTDOWN TRANSACTIONAL. This saves the work for all users without requesting them to log off. The SHUTDOWN TRANSACTIONAL waits for all uncommitted transactions to complete before shutting down the database instance. The SHUTDOWN or SHUTDOWN NORMAL is not really practical because you practically cannot wait for all users to come back to their desks and disconnect from the database. Therefore SHUTDOWN and SHUTDOWN NORMAL commands have the same effect. The NORMAL is the default option if you don’t explicitly specify any option. The SHUTDOWN NORMAL does not require an instance recovery on the next database startup. The database instance will not accept any further database connection. The SHUTDOWN NORMAL option waits for the current users to disconnect from the database before shutting down the database. ![]() Let’s examine each option of the SHUTDOWN command.
