Multiple choice

MARY wants to create an image copy backup that can be used in an incremental backup set. She wants to allocate the C1 channel and create image copies of two data files. She does NOT want the Oracle Server session to perform logical block corruption detection. These image copies will be used in an incremental backup set. Which RUN block set of commands should she use?

  1. rman> RUN 2> CHECK LOGICAL 3> ALLOCATE CHANNEL c1 TYPE DISK; 4> DATAFILE 1 TO '/backup/f1.dbf', 5> DATAFILE 2 TO '/backup/f2.dbf';

  2. rman> RUN 2> ALLOCATE CHANNEL c1 TYPE DISK; 3> COPY LEVEL 0 4> DATAFILE 1 TO '/backup/f1.dbf', 5> DATAFILE 2 TO '/backup/f2.dbf';

  3. rman> RUN 2> ALLOCATE CHANNEL c1 TYPE DISK; 3> DATAFILE 1 TO '/backup/f1.dbf', 4> DATAFILE 2 TO '/backup/f2.dbf';

  4. rman> RUN 2> ALLOCATE CHANNEL c1 TYPE sbt_tape; 3> DATAFILE 1 TO '/backup/f1.dbf', 4> DATAFILE 2 TO '/backup/f2.dbf';

B Correct answer
Explanation

Option B is correct because it specifies COPY LEVEL 0 to create a level 0 image copy suitable for incremental backups, allocates a DISK channel (c1), and omits CHECK LOGICAL as requested. Option A includes CHECK LOGICAL, which performs logical block corruption detection - exactly what Mary wants to avoid. Option C is missing the LEVEL 0 specification required for incremental backup compatibility. Option D allocates an sbt_tape channel instead of the required DISK channel.
