Question #: 24
Topic #: 14

Which two statements are true about space usage in temporary tablespaces?

AWhen a global temporary table instantiation is too large to fit in memory, space is allocated in a temporary tablespace.

BTemporary tablespaces setting Includes quotas to limit temporary space used by a session for that Temporary tablespace.

CA sort will fail if a sort to disk requires more disk space and no additional extent can be found/allocated in/for the sort segment.

DWhen a session consumes all temporary tablespace storage, then the session would hang until the temporary space used by that session is cleared.

ELack of temporary tablespace space for sort operations can be prevented by using temporary tablespace groups.

Show Suggested Answer

Suggested Answer: A, E

Regarding space usage in temporary tablespaces, the following statements are true:

A (Correct): When a global temporary table or a sort operation exceeds the available memory, Oracle Database allocates space in a temporary tablespace to store the temporary data or intermediate results.

E (Correct): Using temporary tablespace groups can prevent insufficient temporary tablespace for sort operations by providing a collective pool of space from multiple temporary tablespaces, which can be used for user sorting operations.

The other options provided have inaccuracies:

B (Incorrect): Oracle does not provide a mechanism for setting quotas on temporary tablespaces. Quotas can be set for permanent tablespaces but not for temporary ones.

C (Incorrect): A sort operation may fail due to insufficient space, but Oracle will attempt to allocate space in the temporary tablespace dynamically. If no space can be allocated, an error is returned rather than a sort failure.

D (Incorrect): If a session consumes all available temporary tablespace storage, Oracle will not hang the session; it will return an error to the session indicating that it has run out of temporary space.

C and D seem spot on to me. A sort operation can definitely fail if it runs out of temporary space, and the session will hang until that space is freed up.

I think statement A is true because temporary table instantiation needs space in temporary tablespace.
