-- | DATABASE : Oracle |
-- | FILE : temp_sort_users.sql |
-- | CLASS : Temporary_Tablespace |
-- | PURPOSE : List all temporary tablespaces and the users performing sorts. |
-- | The statistics will come from the v$sort_usage view which shows |
-- | currently active sorts for the instance. Joining "v$sort_usage" |
-- | to "v$session" will provide the user who is performing a sort |
-- | within the sort segment. |
-- | The CONTENTS column shows whether the segment is created in a |
-- | temporary or permanent tablespace, however, unless you are |
-- | using Oracle8, this should always be temporary. |
-- | 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. |
