Both the processes use PROG_1 as the job template that is already available. The time taken by the jobs are recorded in the TEST_LOG table. While comparing the time taken to create the jobs, the process in exhibit1 takes less time than the process in exhibit2. What is the reason for this?
A. It updates several tables in the SYSTEM tablespace instead of creating new tables.
B. It creates jobs temporarily in memory only.
C. It creates less metadata for the jobs.
D. It writes the job metadata to disk in compressed format.

Backup as compressed backupset duration 2:00 minimize load database ;
A. 2 minutes
B. 2 hours
C. 2 days
D. The command will generate an error.

Q179. Note the following parameters settings in your database:
SGA_MAX_SIZE = 1024M
SGA_TARGET = 700M
DB_8K_CACHE_SIZE = 124M
LOG_BUFFER = 200M
You issued the following command to increase the value of DB_8K_CACHE_SIZE:
SQL> ALTER SYSTEM SET DB_8K_CACHE_SIZE=140M;
What would happen?
A. It will fail because DB_8K_CACHE_SIZE parameter cannot be changed dynamically
B. It will be successful only if the memory is available from the auto tuned components
C. It will fail because an increase in DB_8K_CACHE_SIZE cannot be accommodated within SGA_TARGET
D. It will fail because an increase in the DB_8K_CACHE_SIZE cannot be accommodated within SGA_MAX_SIZE
Q180. You issued the following command on the temporary tablespace LMTEMP in your database:
SQL>ALTER TABLESPACE lmtemp SHRINK SPACE KEEP 20M;
