-- | CLASS : Temporary_Tablespace |
-- | PURPOSE : List all temporary tablespaces and details about the actual |
-- | sort segment. The statistics that come from the v$sort_segment |
-- | view depicts the true space within the temporary segment at |
-- | this current time. This script is RAC enabled. |
-- | NOTE : As with any code, ensure to test this script in a development |
-- | environment before attempting to run it in production. |

PROMPT | Segment Name : The segment name is a concatenation of the |
PROMPT | SEGMENT_FILE (File number of the first |
PROMPT | extent) and the SEGMENT_BLOCK (Block number |
PROMPT | of the first extent) |
PROMPT | Current Users : Number of active users of the segment |
PROMPT | Total Temp Segment Size : Total size of the temporary segment in bytes |
PROMPT | Currently Used Bytes : Bytes allocated to active sorts |
PROMPT | Extent Hits : Number of times an unused extent was found |
PROMPT | in the pool |
PROMPT | Max Size : Maximum number of bytes ever used |
PROMPT | Max Used Size : Maximum number of bytes used by all sorts |
PROMPT | Max Sort Size : Maximum number of bytes used by an |
PROMPT | individual sort |
PROMPT | Free Requests : Number of requests to de-allocate |
