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

The correct RMAN RUN block allocates channel C1 to DISK and uses COPY LEVEL 0 to create image copies of two datafiles. LEVEL 0 creates a base copy usable for incremental backups. CHECK LOGICAL is intentionally omitted because the requirement specifies no logical block corruption detection. Option A is incorrect because CHECK LOGICAL is explicitly not needed. Option C is incorrect because it lacks LEVEL 0 required for incremental backup use. Option D is incorrect because sbt_tape is for tape, not disk backup as specified.
