Hi I am checking in Toad that my tablespace TEST_TS is almost full. To check the tables in this tablespace, I given below commands.

select * from user_tables where tablespace_name='TEST_TS'

select * from user_tab_partitions where tablespace_name='TEST_TS'

Both are displaying no rows.

My doubt is when the tablespace is not used by any tables how It's usage is nearly full? Is there any way to check?

I want to make use of unused tablespace.

Thanks

USER_TABLES will only show your user's tables.
Try DBA_TABLES instead.

Thanks Frank.

I checked DBA_TABLES as well. Yet the query returns no rows.

Also I am creating an index and specified a tablespace name with Create index(Index_tablespace) and I am getting error ORA-01652: unable to extend temp segment by 1024 in tablespace Index_tablespace.

Thanks

Could be there are no tables in there but lots of indexes. Try querying dba_extents.

To know what's inside a tablespace query DBA_SEGMENTS.
A segment is the physical part of an object (a table for instance).
A table is a logical object which may be spread over one or many segments.
A tablespace contains segments not tables (but the segments of tables).

Michel

Yes! the tablespace is having only Indexes. Will move these indexes to another tablespace. Thanks a lot.

Now the other question is I can see a particular tablespace usage is only 1%. Yet when i tried to create index in that tablespace, I am getting error ORA-01652: unable to extend temp segment by 1024 in tablespace TEMP_TS.

Thanks

Enlarge the tablespace.
Do not explain what you have as you don't understand what happens you are not able to clearly, precisely and accurately explain it.
Instead, show it: copy and paste your SQL*Plus session.

ORA-12801: error signaled in parallel query server P000
ORA-01652: unable to extend temp segment by 1024 in tablespace TEMP_INDEX_TS

But I can see in Toad TEMP_INDEX_TS usage is less than 1%

Thanks

TOAD is a mess ("Those who live by the GUI, die by the GUI.").
Tablespace usage is meaningless for a temporary tablespace.
