How do I find used/free space in a TEMPORARY tablespace?

Question

Hello guys,

Anybody can tell me
How do I find used/free space in a TEMPORARY tablespace?

Answer 1

Unlike normal tablespaces, true temporary tablespace information is not listed in DBA_FREE_SPACE. Instead use the V$TEMP_SPACE_HEADER view:

SELECT tablespace_name, SUM (bytes used), SUM (bytes free)
FROM V$temp_space_header
GROUP BY tablespace_name;
