Question 46

In your Database, the TBS PERCENT USED parameter is set to 60 and the TBS PERCENT FREE parameter is set to 20. Which two storage-tiering actions might be automated when using information Lifecycle Management (ILM) to automate data movement? (Choose two.)

A. The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
B. Setting the target tablespace to read-only
C. The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
D. Setting the target tablespace offline
E. The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED

Correct Answer:BC
The value for TBS_PERCENT_USED specifies the percentage of the tablespace quota when a tablespace is considered full. The value for TBS_PERCENT_FREE specifies the targeted free percentage for the tablespace. When the percentage of the tablespace quota reaches the value of TBS_PERCENT_USED, ADO begins to move data so that percent free of the tablespace quota approaches the value of TBS_PERCENT_FREE. This action by ADO is a best effort and not a guarantee.

Question 49

You upgrade your Oracle database in a multiprocessor environment. As a recommended you execute the following script: SQL > @utlrp.sql
Which two actions does the script perform? (Choose two.)

A. Parallel compilation of only the stored PL/SQL code
B. Sequential recompilation of only the stored PL/SQL code
C. Parallel recompilation of any stored PL/SQL code
D. Sequential recompilation of any stored PL/SQL code
E. Parallel recompilation of Java code
F. Sequential recompilation of Java code

Correct Answer:CE
utlrp.sql and utlprp.sql
The utlrp.sql and utlprp.sql scripts are provided by Oracle to recompile all invalid objects in the database. They are typically run after major database changes such as upgrades or patches. They are located in the
$ORACLE_HOME/rdbms/admin directory and provide a wrapper on the UTL_RECOMP package. The utlrp.sql script simply calls the utlprp.sql script with a command line parameter of "0". The utlprp.sql accepts a single integer parameter that indicates the level of parallelism as follows.
0 - The level of parallelism is derived based on the CPU_COUNT parameter. 1 - The recompilation is run serially, one object at a time.
N - The recompilation is run in parallel with "N" number of threads.
Both scripts must be run as the SYS user, or another user with SYSDBA, to work correctly. References:
