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?
Correct Answer: B,C
Explanation/Reference:
Explanation:
The threshold for activating tiering policies is based on two parameters:
TBS PERCENT USED
TBS PERCENT FREE
Both values can be controlled by the DBMS_ILM_ADMIN package.
TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively. Hence, whenever the
source tablespace's usage percentage goes beyond 85 percent, any tiering policy specified on its objects
will be executed and objects will be moved to the target tablespace until the source tablespace becomes at
least 25 percent free. Note that it is possible to add a custom condition to tiering policies to enable
movement of data based on conditions other than how full the tablespace is.
In addition, the READ ONLY option must be explicitly specified for the target tablespace.
