QUESTION 151
Which command will result in a trace file being created with the create controlfile command contained in it?

A.    alter database backup controlfile;
B.    alter database backup controlfile to trace;
C.    alter database controlfile backup;
D.    alter database controlfile backup to ‘/ora01/oracle/ctrl_backup.ctl’;

Explanation:
Backing Up Control Files
Use the ALTER DATABASE BACKUP CONTROLFILE statement to back up your control files. You have two options:
Back up the control file to a binary file (duplicate of existing control file) using the following statement:
ALTER DATABASE BACKUP CONTROLFILE TO ‘/oracle/backup/control.bkp’;
Produce SQL statements that can later be used to re-create your control file:
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
This command writes a SQL script to a trace file where it can be captured and edited to reproduce the control file. View the alert log to determine the name and location of the trace file.

Making User-Managed Backups of Online Read/Write Tablespaces
You must put a read/write tablespace in backup mode to make user-managed data file backups when the tablespace is online and the database is open.
The ALTER TABLESPACE … BEGIN BACKUP statement places a tablespace in backup mode.
In backup mode, the database copies whole changed data blocks into the redo stream. After you take the tablespace out of backup mode with the ALTER TABLESPACE … END BACKUP or ALTER DATABASE END BACKUP statement, the database advances the data file checkpoint SCN to the current database checkpoint SCN.
When restoring a data file backed up in this way, the database asks for the appropriate set of redo log files to apply if recovery is needed. The redo logs contain all changes required to recover the data files and make them consistent.

Answer: A
Explanation:
Changing the Database Archiving Mode
To change the archiving mode of the database, use the ALTER DATABASE statement with the ARCHIVELOG or NOARCHIVELOG clause. To change the archiving mode, you must be connected to the database with administrator privileges (AS SYSDBA).
The following steps switch the database archiving mode from NOARCHIVELOG to ARCHIVELOG:
Shut down the database instance.
SHUTDOWN IMMEDIATE
An open database must first be closed and any associated instances shut down before you can switch the database archiving mode. You cannot change the mode from ARCHIVELOG to NOARCHIVELOG if any data files need media recovery.
Back up the database.
Before making any major change to a database, always back up the database to protect against any problems. This will be your final backup of the database in NOARCHIVELOG mode and can be used if something goes wrong during the change to ARCHIVELOG mode.
Edit the initialization parameter file to include the initialization parameters that specify the destinations for the archived redo log files .
Start a new instance and mount, but do not open, the database.
STARTUP MOUNT
To enable or disable archiving, the database must be mounted but not open.
Change the database archiving mode. Then open the database for normal operations.
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;
Shut down the database.
SHUTDOWN IMMEDIATE
Back up the database.
Changing the database archiving mode updates the control file. After changing the database archiving mode, you must back up all of your database files and control file. Any previous backup is no longer usable because it was taken in NOARCHIVELOG mode.

QUESTION 111
You have configured flash recovery area in your database and you set the following Initialization parameters for your database instance:
LOG_ARCHIVE_DEST 1 = ,,LOCATION=/disk1/arch MANDATORY’
LOG _ARCHIEVE_DEST 2 = ,,LOCATION=/disk2/arch’
LOG_ARCHIVK_DEST_3 = ,,LOCATION=/diSk3/arch
LOG_ARCH1VK_DEST_4 = ‘ LOCATION=/disk4/arch’
LOG_ARCHIVE_MIN-SUCCEED_DEST = 2
While the database instance is functional, you realized that the destination set by the LOG_ARCHIVE_DEST_I parameter Is not available for the archived redo log file to be created in. All redo log groups have been used. What happens in an event of log switch?

A.    The online redo log file Is not allowed to be overwritten.
B.    The archived redo log files are written to the flash recovery area until the MANDATORY destination is
made available.
C.    The database instance will crash because the archived redo log file cannot be created in a destination
set as MANDATORY.
D.    The destination set by the LOG_ARCHIVE_DEST_1 parameter is ignored and the archived redo log files
are created in the next two available locations to guarantee archive log success.

Answer: D
Explanation:
http://docs.oracle.com/cd/E11882_01/server.112/e25494/archredo.htm#ADMIN11346
The optional initialization parameter LOG_ARCHIVE_MIN_SUCCEED_DEST=n determines the minimum number of destinations to which the database must successfully archive a redo log group before it can reuse online log files. The default value is 1. Valid values for n are 1 to 2 if you are using duplexing, or 1 to 31 if you are multiplexing.
The LOG_ARCHIVE_DEST_n parameter lets you specify whether a destination is OPTIONAL (the default) or MANDATORY. The LOG_ARCHIVE_MIN_SUCCEED_DEST=n parameter uses all MANDATORY destinations plus some number of non-standby OPTIONAL destinations to determine whether LGWR can overwrite the online log.
When you specify a value for LOG_ARCHIVE_MIN_SUCCEED_DEST=n, Oracle Database will treat at least one local destination as MANDATORY, because the minimum value for LOG_ARCHIVE_MIN_SUCCEED_DEST is 1.

Answer: D
Explanation:
http://docs.oracle.com/cd/E11882_01/server.112/e41134/log_arch_dest_param.htm#SBYDB01109
MANDATORY
Specifies that filled online log files must be successfully archived to the destination before they can be reused.
If MANDATORY is not specified, then, by default, the destination is considered to be optional.
At least one destination must succeed, even if all destinations are optional. If archiving to an optional destination fails, the online redo log file is still available for reuse and may be overwritten eventually. However, if the archival operation of a mandatory destination fails, online redo log files cannot be overwritten.
