Once a tablespace has been dropped, the objects and data in it will no longer be available. To recover them can be a time consuming process. Oracle recommends a backup before and after dropping a tablespace.
Are you sure you want to delete Tablespace TEMP3?
Delete associated datafiles from the OS
When I checked at EM, there are locks too..
SMON has locked the system
What should I do now?

Drop temp tablespace goes forever

Hi,
Trying to drop temp tablespace.
I made new default temp tablespace and that part went fine. I can see system using it immediately.
Then I tried to drop the old one.
drop tablespace temp including contents and datafiles;
.... no go .... altough content is gone now. Tablespace was full before this now it's empty.
My command still hangs in sqlplus.
Any idea?

You either wait until it's finish. Or kill the session that held it.
SELECT s.sid,
       s.serial#,
       s.osuser,
       s.program
FROM   v$session s;
ALTER SYSTEM KILL SESSION 'sid,serial#'

How to identify temp tablespace user in the past

can anyone guide me on how to identify temp tablespace users and corresponding temp space amount they used in the past?
we have this situation where in we need to identify the top temp tablespace user last jan 1 around a specific time.
is this possible? do these get stored in one of the tables in the dictionary? any sql statement?
thanks.

How to monitor temp tablespace

I server in 11gR2 and 10gR2.
Is there a way to monitor its usage, like, who is using it, how much space a session is using, what are the objects crated, ie. temp tables.
Thanks.

I am trying to drop temp tablespace as below command. It is running since nine hours I am not understand why it is taking too much time. FYI I have created a new temp and assigned to default temporary tablespace. Even I connected with new session and run “drop tablespace temp” it is also running since one hour. Suggest me.

How to drop users tablespace

Hey to all
     I want to drop USER tablespace wid data file but as we know many oracle users Scott OE data reside in users. How can I protect their data. One method which I read on net to export and import once again is quite cumbersome I run this query
SELECT
owner
, segment_name
, segment_type
FROM
dba_segments
WHERE
tablespace_name='USERS'
it give me two user OE and SCOTT. How can I protect their data before drop the user tablespace

Hi..
As you said direct load takes place, then the rows which are inserted are always inserted above the HWM.So the datafile size size kept on increasing.
i read about segment advisor i run the advisor it shrink the segment but users tablespace size on OS still 200 GB could anyone tell why??You would have run alter table <table_name> shrink space; -- This statement will procede in two steps:
- The first step makes the segment compact by moving rows further down to free blocks at the beginning of the segment.
- The second step adjusts the high watermark. For this Oracle needs an exclusive table lock,but for a very short moment only.
The HWM goes below, and table are now more well organized.This command doesn't resize the datafile at the OS level.So, the datafile sizes will remain the same.One thing which you can do is resize(decrease) the datafile.

To shrink the size of TEMP tablespace

Dear all,
There is a databse with RAC, now in OEM the size of TEMP tablespace has been reached at 99.9%. now we want to shrink the size of TEMP tablespace.
how to we do that???????
plz help me...........

Temporary tablespaces usually show they are full, however this space is not actually in use. It is rather allocated. Oracle has evaluated the best way to obtain the most of performance, and he said it is better to allocate once than allocate-deallocate-reallocate extents, so temporary space is not 'released'.
If you want to feel psychologically more confortable with lower allocated space, you can drop your tablespace (create an interim default temporary tablespace first) and recreate it.
You can also rebuild temporary datafiles:
alter tablespace temp add tempfile 'C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP01.dbf' size 32m;
SQL> select name from v$tempfile;
NAME
C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP.DBF
C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP01.DBF
SQL> alter database tempfile 'C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP01.DBF' drop including datafiles;
Database altered.

Drop temp tables

how to drop temp tables if i created with same name in different sessions
create table #temp(id int)
(with same in different sessions)

In addition to Olaf's, if you create temp table in two different sessions, you will find the 2 #test in the TempDB.sys.tables.
CREATE TABLE #test (id int);
Either the different object_ids or the "same" names indicate they are
different temp tables. The same named local temp tables created in different sessions are traced with a 12 suffix in the tempdb.sys.tables. That's why when creating temp tables, maximum length can be of 116 characters only, while creating a
table, the maximum is 128.
The fragment referenced from the BOL
You can create local and global temporary tables. Local temporary tables are visible only in the current session; global temporary tables are visible to all sessions.
All local temporary tables are dropped automatically at the end of the current session.
You can read more from the below link.

Oracle dbsonsole not running after drop temp files

before drop temp tablespace
i was create temp2 tablespace as default temp tablespace
after that
i have droppped temp files last to first
temp4.dbf ..3..2
when i have clicked to delete temp table space in dbconsole
after a few time dbconsole not running
in iexplore
i have tired to start db control again with emctl start dbconsole
it was already running
then i have command
emctl status dbconsole
is not running
i have looked log file i see temp file warning
now what can i do to start dbconsole again

Dbconsole doesn't work proper without temp files. So you should create temp file for temporary tablespace in some other tool.

Doubt in considering temp tablespace's free space

Hi All,
Database: oracle 11.2
Operating System: AIX
I want to know how much free space available in my temp tablespace
I ran below scripts
select sum((bytes_free)/1024/1024/1024) GB from v$temp_space_header
+52.904296875+
select (tablespace_size)/1024/1024/1024 tablespace_size_in_gb,
+(allocated_space)/1024/1024/1024 allocated_space_in_gb,+
+(free_space)/1024/1024/1024 free_space_in_gb+
from dba_temp_free_space
tablespace_size_in_gb: 98.9990234375
allocated_space_in_gb: 46.0947265625
free_space_in_gb:151.81640625
So my doubt is which one from above two script gives actual free space information ?
Also in dba_temp_free_space view why free space size > tablespace size ?

v$temp_space_header shows you how big the temp tablespace has got since the database was restarted. It doesn't give you the current free/used space.
See the link for dba_temp_free_space, but I think it may be the way it reports free space which is why you're seeing it as more than the actual tablespace. As you can see form the description "space that is currently allocated and available for resuse" is calculated for both allocated space and free space.
http://docs.oracle.com/cd/B28359_01/server.111/b28320/statviews_5056.htm
>
ALLOCATED_SPACE = space that is currently allocated and used + space that is currently allocated and available for reuse
FREE_SPACE = space that is currently allocated and available for reuse + space that is currently unallocated>
I use the below script which I've plagiarised from somewhere ages ago to get the used/free temp space.
SELECT   A.tablespace_name tablespace, D.mb_total,
         SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_used,
         D.mb_total - SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_free
FROM     v$sort_segment A,
         SELECT   B.name, C.block_size, SUM (C.bytes) / 1024 / 1024 mb_total
         FROM     v$tablespace B, v$tempfile C
         WHERE    B.ts#= C.ts#
         GROUP BY B.name, C.block_size
         ) D
WHERE    A.tablespace_name = D.name
GROUP by A.tablespace_name, D.mb_total;

Unusual Temp Tablespace Growth

Hi ,
We have noticed unsual temp tablespace growth when concurrent users are accessing OLAP cube through BI Bean crosstabs.
On an average 3 to 4 GB temp tablespace is consumed for each new user. OLAP cube has 7 dimensions and 1.2 million records and is fully precalculated.
This causes the system to fail as a result of temp tablespace getting full.
Can somebody please let me know what can be the root causes?.
Thanks in advance.
Harry

Hi there,
It is not unusual for OLAP queries to make significant use of temp tablespace. 3-4GB doesn't sound unreasonable to me. The actual amount used depends on factors such as the type of activity and the number of users.
There is a brief description of how OLAP uses temp tablespace here :- http://download.oracle.com/docs/cd/B28359_01/olap.111/b28124/admin.htm#sthref442
Note the lower than standard setting 'EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K' - if you are not already using this setting then you may find that it lowers temp space usage as the default setting is usually 1024K or even 4096K
I hope this helps
