Question

Which of these steps is optional in implementing automatic undo management?

a) Configuring the rollback segments
b) Enabling the UNDO_RETENTION parameter
c) Setting the UNDO_MANAGEMENT parameter to AUTO
d) Initializing the database

Answer 1

Configuring the rollback segments is the optional step in implementing automatic undo management.

Step-by-step explanation:

In implementing automatic undo management, the step that is optional is a) Configuring the rollback segments. With automatic undo management, Oracle manages the undo data in a tablespace called UNDO tablespace. This eliminates the need to manually configure and manage rollback segments.

Other steps involved in implementing automatic undo management include:

• b) Enabling the UNDO_RETENTION parameter: This parameter specifies the minimum amount of time that Oracle should retain undo data before it becomes available for reuse.
• c) Setting the UNDO_MANAGEMENT parameter to AUTO: This parameter enables automatic undo management.
• d) Initializing the database: This step is necessary to create the necessary files and structures for the database.
