NLS_COMP specifies the collation behavior of the database session. Values:
BINARY
Normally, comparisons in the WHERE clause and in PL/SQL blocks is binary unless you specify the NLSSORT function.
LINGUISTIC
Comparisons for all SQL operations in the WHERE clause and in PL/SQL blocks should use the linguistic sort specified in the NLS_SORT parameter. To improve the performance, you can also define a linguistic index on the column for which you want linguistic comparisons.
ANSI
A setting of ANSI is for backwards compatibility; in general, you should set NLS_COMP to LINGUISTIC

Because of a logical corruption in your production database, you wanted to perform Tablespace Point in Time Recovery (TSPITR).

Which statement about using RMAN stored scripts is true?

  • A. To create and execute an RMAN stored script, you must use a recovery catalog.
  • B. When executing a stored script and a command fails, the remainder of the script is executed, and a message is written to the alert log file.
  • C. RMAN stored scripts can always be executed against any target database that is registered in the recovery catalog.
  • D. When you execute a stored script, it always executes using the persistent channelsettings previously set with the CONFIGURE command.

Answer: A

Explanation:
About Stored Scripts
You can use a stored script as an alternative to a command file for managing frequently used sequences of RMAN commands. The script is stored in the recovery catalog rather than on the file system.
Stored scripts can be local or global. A local script is associated with the target database to which RMAN is connected when the script is created, and can only be executed when you are connected to that target database. A global stored script can be run against any database registered in the recovery catalog, if the RMAN client is connected to the recovery catalog and a target database.
The commands allowable within the brackets of the CREATE SCRIPT command are the same commands supported within a RUN block. Any command that is legal within a RUN command is permitted in the stored script. The following commands are not legal within stored scripts: RUN, @, and @@.
When specifying a script name, RMAN permits but generally does not require that you use quotes around the name of a stored script. If the name begins with a digit or is an RMAN reserved word, however, then you must put quotes around the name to use it as a stored script name. Consider avoiding stored script names that begin with nonalphabetic characters or that are the same as RMAN reserved words.

NEW QUESTION 10

In Recovery Manager (RMAN), you are taking image copies of the data files of your production database and rolling them forward at regular intervals. You attempt to restart your database.

Because a media failure caused the data file to be damaged, you want to place the data file in a different location while restoring the file.
Which option must you consider for this task?

  • A. using only the RMAN SWITCH command to set the new location for the data file
  • B. placing the database in the MOUNT state for the restore and recovery operations.
  • C. using an RMAN RUN block with the SET NEWNAME and then the SWITCH command.
  • D. configuring two channels: one for the restore operation and the other for the recovery operation

Answer: C
