QUESTION NO: 2
You are the DBA supporting an Oracle 11g Release 2 database and wish to move a table containing several DATE, CHAR, VARCHAR2, and NUMBER data types, and the table's indexes, to another tablespace.
The table does not have a primary key and is used by an OLTP application.
Which technique will move the table and indexes while maintaining the highest level of availability to the application?
A. An ALTER TABLE MOVE to move the table and ALTER INDEX REBUILD to move the indexes.
B. Oracle Data Pump.
C. Edition-Based Table Redefinition.
D. Online Table Redefinition.
E. An ALTER TABLE MOVE to move the table and ALTER INDEX REBUILD ONLINE to move the indexes.
Answer: D
Explanation
* Oracle Database provides a mechanism to make table structure modifications without significantly affecting the availability of the table. The mechanism is called online table redefinition. Redefining tables online provides a substantial increase in availability compared to traditional methods of redefining tables.
* To redefine a table online:
Choose the redefinition method: by key or by rowid
* By key-Select a primary key or pseudo-primary key to use for the redefinition. Pseudo-primary keys are unique keys with all component columns having NOT NULL constraints. For this method, the versions of the tables before and after redefinition should have the same primary key columns. This is the preferred and default method of redefinition.
* By rowid-Use this method if no key is available. In this method, a hidden column named M_ROW $ $ is added to the post-redefined version of the table. It is recommended that this column be dropped or marked as unused after the redefinition is complete. If COMPATIBLE is set to 10.2.0 or higher, the final phase of redefinition automatically sets this column unused. You can then use the ALTER TABLE
... DROP UNUSED COLUMNS statement to drop it.
You cannot use this method on index-organized tables.
Note:
* When you rebuild an index, you use an existing index as the data source. Creating an index in this manner enables you to change storage characteristics or move to a new tablespace. Rebuilding an index based on an existing data source removes intra-block fragmentation. Compared to dropping the index and using the CREATE INDEX statement, re-creating an existing index offers better performance.
Incorrect:
Not E: Edition-based redefinition enables you to upgrade the database component of an application while it is in use, thereby minimizing or eliminating down time.
QUESTION NO: 3
You conned using SQL Plus to the root container of a multitenant container database (CDB) with SYSDBA privilege.
The CDB has several pluggable databases (PDBs) open in the read/write mode.
There are ongoing transactions in both the CDB and PDBs.
What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?
A. The shutdown proceeds immediately. The shutdown proceeds as soon as all transactions in the
PDBs are either committed or rolled hack.
B. The shutdown proceeds as soon as all transactions in the CDB are either committed or rolled back.
C. The statement results in an error because there are open PDBs.
D. The shutdown proceeds as soon as all transactions in both the CDB and PDBs are either committed or rolled back.
Answer: B
Explanation
* SHUTDOWN [ABORT | IMMEDIATE | NORMAL | TRANSACTIONAL [LOCAL]]
Shuts down a currently running Oracle Database instance, optionally closing and dismounting a database. If the current database is a pluggable database, only the pluggable database is closed. The consolidated instance continues to run.
Shutdown commands that wait for current calls to complete or users to disconnect such as
SHUTDOWN NORMAL and SHUTDOWN TRANSACTIONAL have a time limit that the SHUTDOWN command will wait. If all events blocking the shutdown have not occurred within the time limit, the shutdown command cancels with the following message:
ORA-01013: user requested cancel of current operation
* If logged into a CDB, shutdown closes the CDB instance.
To shutdown a CDB or non CDB, you must be connected to the CDB or non CDB instance that you want to close, and then enter SHUTDOWN Database closed.
Database dismounted.
Oracle instance shut down.
To shutdown a PDB, you must log into the PDB to issue the SHUTDOWN command.
SHUTDOWN
Pluggable Database closed.
Note:
* Prerequisites for PDB Shutdown
When the current container is a pluggable database (PDB), the SHUTDOWN command can only be used if:
The current user has SYSDBA, SYSOPER, SYSBACKUP, or SYSDG system privilege.
The privilege is either commonly granted or locally granted in the PDB.
The current user exercises the privilege using AS SYSDBA, AS SYSOPER, AS SYSBACKUP, or AS SYSDG at connect time.
To close a PDB, the PDB must be open.
