Explanation/Reference:

Section: Database Architecture & Resource Management, RAC, ASM

You can enable resumable space allocation at the instance level by modifying the RESUMABLE_TIMEOUT

initialization parameter to a nonzero value, or youcan change the value of the RESUMABLE_TIMEOUT

parameter dynamically by issuing the following statement:

ALTER SYSTEM SET RESUMABLE_TIMEOUT=<nonzero_value>;

Issuing the ALTER SYSTEM ENABLE RESUMABLE;statement is incorrect. This statement would generate an

error on execution because the syntax is incorrect.

Issuing the ALTER SESSION ENABLE RESUMABLE;statement is incorrect. You issue the ALTER SESSION

ENABLE RESUMABLE;statement to enable resumable space allocation at the session level, not to enable

resumable space allocation at the instance level.
