To shutdown a particular database, immediately restart and open it, allow access only to users with the RESTRICTED SESSION privilege, and use the parameter file MYINIT.ORA. To start an instance using the parameter file TESTPARM without mounting the database, enter To start an instance using the standard parameter file, mount the default database, and open the database, enter STARTUP OPEN RECOVER mounts and opens the database even when recovery fails. STARTUP with no arguments is equivalent to STARTUP OPEN. You cannot be connected to a shared server via a dispatcher. You must be connected to a database as SYSOPER, or SYSDBA. Once the downgrade completes, the database should be shut down and restarted normally. When run, downgrade scripts transform an installed version or release of Oracle Database into a previous version, for example, to downgrade an Oracle10 g database to an Oracle9 i database. See the Oracle Database Upgrade Guide for details about preparing for, testing and implementing a database version downgrade. Starts the database in OPEN DOWNGRADE mode and sets system initialization parameters to specific values required to enable database downgrade scripts to be run. Once the upgrade completes, the database should be shut down and restarted normally. When run, upgrade scripts transform an installed version or release of an Oracle database into a later version, for example, to upgrade an Oracle9 i database to Oracle Database 10 g. See the Oracle Database Upgrade Guide for details about preparing for, testing and implementing a database version upgrade. UPGRADE should only be used when a database is first started with a new version of the Oracle Database Server. ![]() ![]() ![]() Starts the database in OPEN UPGRADE mode and sets system initialization parameters to specific values required to enable database upgrade scripts to be run. If a redo log file is not found in the expected location, recovery continues as if AUTORECOVERY is disabled, by prompting you with the suggested location and name of the subsequent log files that need to be applied. Recovery proceeds, if necessary, as if AUTORECOVERY is set to ON, regardless of whether or not AUTORECOVERY is enabled. 1 Answer Sorted by: 3 In case of RAC database there are gv views. Only complete recovery is possible with the RECOVER option. STARTUP RECOVER has the same effect as issuing the RECOVER DATABASE command and starting an instance. Specifies that media recovery should be performed, if necessary, before starting the instance. If no database name is specified, the database name is taken from the initialization parameter DB_NAME.Ĭauses the database not to be mounted upon instance startup. Suppresses the display of System Global Area information for the starting instance.ĭbname is the name of the database to mount or open. For example, the default file is $ORACLE_HOME/dbs/init$ORACLE_SID.ora on UNIX, and ORACLE_HOME\database\initORCL.ora on Windows. If the default spfile isn't found, the server then attempts to access a default pfile. If PFILE is not specified, the server attempts to access a default server parameter file (spfile). Specifies the client parameter file to be used while starting the instance. Later, you can use the ALTER SYSTEM command to disable the restricted session feature. Only enables Oracle Database users with the RESTRICTED SESSION system privilege to connect to the database. FORCE is useful while debugging and under abnormal circumstances. If the current instance is running and FORCE is not specified, an error results.
