TEMP datafile siae
Hi,
my TEMP datafile increases to 32G.
I have shudowned and restarted my DB no think allways 32G.
Why it do that and how correct the situation.
Any suggestion, thanks.
Dont keep temp datafiles to auto extend option.
You dont need to worry about temp tbs not releasing the space until you get an error like 'unable to extend temp tablespace extents'. Typicall temp tbs behaviour is like that,i.e. once allocated extends, won't deallocated, in fact, kept for future usage.

TEMP datafiles for temporary tablespaces don't have same timestamp
Hi,
This is what I have done:
Installing 10G2 on XP PRO with sample database.
Tried to install Designer Repository with the Wizard, created a user for the toolkit, that failed.
Added 1 temp tablespace size 20Meg from OEM console.
Dropped cascade Toolkit schema owner and recreated it
Tried to install Designer Repository, that failed again
Added 1 temp tablespace size 1giga from OEM console, failed again to import
Dropped cascade Toolkit schema owner and recreated it
Tried to install Designer Repository, that failed again
Gave up for now: I have located a doc about installing manually by running scripts, will do as soon as I feel at ease with OEM.
Then I put the PC on snooze while database was up, crashed it.
Stopped the services, checked the logs, restarted manually and slowly, base up.
Now both extra TEMP datafiles are lagging behind, seen from Windows explorer, but the tablespaces are seen as online from oem, not seen from sqlplus dba_tablespaces view.
So the question is:
Are the TEMP datafiles supposed to stay in sync with the others or is it ok if they show timestamps dating three days back, provided there has not been any users transactions in the database?
I checked the 10G2 DBA online doc, but I can't find where it's mentioned.
Many thanks if you can help.Hi,
Everything allright, they do show!
I'm a bit wary about resizing anything, maybe you remember the resizing bug for SYSTEM tablespace in version 7?
I have to beef up on DBA tricks.
Since I also have a 1 Giga Users tablespace, I'll do some heavy Inserting and Updating and Sorting see if that tickles the Temps.
Many thanks for your prompt reply.

Hi,

Any suggestion, Thanks.First, if you have your TEMP tablespace set to autoextend without specifying a maximum size, I would address that problem.
Second, how big should your TEMP space be?
Third, if your TEMP space grew to 32 GB, someone was either running a tremendous query or a large number of people were simultaneously running rather large queries. Depending on whether this was appropriate-- maybe someone really needed to generate a report that sorted 32 GB of data-- we can suggest ways to move forward.

We have 4 temp datafiles is one of our database and three are 99% and last one 99% full.
Solutions:
Let me know which solution is better
1. I just keep adding TEMP datafiles.
2. Delete the previous one and add the new one so that I can get some free space on disk.
3. Re boot the server so that all temp files gets empty and I don't need to do anything(its not possible becuase we have 24/7 datebase)...
Please give me your suggestions
ThanksIf the TEMP space is not being released for a long time, you could activate SMON by the below trick
SELECT PCT_INCREASE FROM DBA_TABLESPACES WHERE TABLESPACE='TEMP';
note the percentage
ALTER TABLESPACE TEMP DEFAULT STORAGE (PCTINCREASE 10);
It could be 10 or any number between 1 and 100.
wait for a while and return it back to the previously defined percentage
This will release the TEMP segments -
Not sure if I hit the right forum here.
ORACLE RDBMS Version: 10.2.0.1.0
I'm doing some 10g studying and came across recovering from non-critical files.
Now the various books (2) indicate that you should take some action when you startup the database.
However, when I delete the datafile making up the temp tablespace; at startup that file is just regenerated as;
With out going into all the details this action:
oracle@blue:/u1/app/oracle/oradata/qbase> rm -rf tempdijk01.dbf
(this is the datafile of the default temp tbs).
Lead to during db startup:
Mon Mar 5 23:58:17 2007
Re-creating tempfile /u1/app/oracle/oradata/qbase/tempdijk01.dbf
Q. are there other circumstances that might need interaction at db startup, like drop and recreate the
temp tbs is mount etc.?
Thanks.
-TOracle tempfile happen to be very special datafile. The behavior of this file doesn't represent other datafiles of database.
If you remove a regular datafile from OS level, you will need to do recovery before you can open the database for use.

We are on 9.2.0.5. I had 2 datafiles for my TEMP tablespace, each at 2,048 mb in size. One file was set for autoextend to 32 gb. In a matter of 2 hours, this datafile grew to 100% max size and the other grew to 99.99%. To keep our application running, I added a new 2,048 mb to the tablespace. The problem was traced to a bad query with a strange sort. (Query has since been deleted). My question: Can I shutdown the database, drop the datafiles, create 2 more 2,048 mb datafiles and restart the database? I really want to reclaim the file space. Would this work?
The DB shutdown and restarting fine. However I attempted to resize the datafiles using the following script:
ALTER DATABASE TEMPFILE 'F:\....\TEMP01.DBF'
RESIZE 2048M;
OEM is indicating the file is full and therefore I get the message it I can't resize due to extend past the size of it is currently at.
What needs to be done to resize or to clear the data consuming the datafiles? -
if i use EM to add datafile i gave name temp01 instead temp01.dbf. any difference both of these or oracle automatically add .dbf extention??? i'm adding file using enterprize edtion
Adeel,
No there is no difference in the working of both.EM doesn't add the extension. You can create a tempfile,or any file with any extension you want and it will be used by Oracle.SQL> select * from dba_temp_files;

Hi all,
The temporary tablespace datafiles were old and occupy lot of space. Can I safely remove them or shall I backup them to disk.
Thanks.786923 wrote:

Thanks.Do not need backup of temp tablespace,but you can create new temporary tablespace and delete old ts as
create temporary tablespace new_tempts tempfile 'tempfile_full_path' size <size> autoextend on next 30M;
alter database default temporary tablespace new_tempts;
drop tablespace old_ts_name; -
How do you move the Temp01.DBF from the D: to E:
I'm using the ALTER DATABASE RENAME FILE but I get an error of;
"nonexistsent logfile datafile or tempfile"
The Datafile definitely exists in the D: and E: where I'm trying to move it too.
This is on 9i.hi
before dropping create a tablespace in desired location and make it default then drop the previous one.
u can also take the datafile offline and then rename it and back online.
but before doing anything u check the temporary segments whether any user is still using it.
You can view the allocation and deallocation of space in a temporary tablespace
sort segment using the V$SORT_SEGMENT view, and the V$SORT_USAGE view
identifies the current sort users in those segments.

Restored coldbackup and having trouble with TEMP tablespace
Hi, i succesfully restored from a coldbackup on solaris.(oracle 9.2)
i can log on to database using toad, query the database, but when i try to take an export or something i got the error
EXP-00056: ORACLE error 1157 encountered
ORA-01157: cannot identify/lock data file 203 - see DBWR trace file
ORA-01110: data file 203: '/sun2int1/oracle92/app/oracle/product/9.2.1/oradata/TPRS/temp03.dbf'

ORA-06512: at "SYS.DBMS_METADATA", line 1140
ORA-06512: at line 1
EXP-00000: Export terminated unsuccessfully
when i did the restore, i simply renamed the datafiles and redo logs.
But i didnt rename the TEMP datafile, as you can not rename it with a "alter database rename file ..." command
so thats the problem!
i planned to create a new default temp. tablespace, and simply make it default and drop the other one. but it does not work!
i tried to execute:
CREATE TEMPORARY TABLESPACE temp4 TEMPFILE '/oracleAS/TPRS/oradata/TPRS/temp4.dbf' SIZE 5M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE unlimited
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;
create temporary tablespace temp01 tempfile '/oracleAS/TPRS/oradata/TPRS/temp01.dbf' size 100M;
but they all hang! i wait, but nothing happens! (and alert log does not log anything too)
and finally i tried to drop the default tablespace, and i couldnt drop it as i thought. (ORA-12906: cannot drop default temporary tablespace
So, im stuck and i beleive i have to RENAME the datafile for temporary tablespace. how can i do this?

Temp tablespace full at startup
Hi,
my temp tablespace appears full at database startup. I know it is full because the collecting statistics process can not be executed since temp tablespace can not grow (autoextend off). I had to add another temp datafile to get the statistics but first one continues full after each restart.
Is this any signal of malfunction?
Thanks for all.
Greetings.ok. I think all is understood.
DBMS_STATS.GATHER_SCHEMA_STATS probably needed more disk than 1.5 GB (my old temp tablespace), so the result was
ERROR en línea 1:
ORA-01652: no se ha podido ampliar el segmento temporal con 128 en el
tablespace TEMP
ORA-06512: en "SYS.DBMS_STATS", línea 9136

ORA-06512: en "SYS.DBMS_STATS", línea 9854
ORA-06512: en "SYS.DBMS_STATS", línea 9831
ORA-06512: en línea 1
Then adding new datafile (1.5 GB more) process could finish. Database continues growing, process always had finished not yesterday: the day of needing full temp tablespace came.
Tell me if I am wrong.
Thanks a lot. -
Dear All,
My database server 11gR1 is running on Linux operating system. The disk where my database exists is almost 80% used. I need to shrink datafile, is there any such option available.
When i take dump of my database it is like 3.5 GB but the database size shown in the space summary of oracle enterprise manager is like 22 GB while the tablespace shows only 20% free space in it.
What is the best possible way to perform this function? Kindly help me. If there is anything else you need to know kindly ask.
Regards, Imran BaigIdentify which tablespace has grown big.
It could be the tablespace which hold application tables or undo datafiles or temp datafiles.
If it is the tablespace which hold the application data, find which object is big (from dba_segments).
It could be like some table is created with 15Gb storage space and contain only 1Gb of data.

Allocated space = 8534360064
Actual used space = 46874624
PL/SQL procedure successfully completed.The COMS table was allocated around 8Gb but it has only 44Mb of data.
So in this case the space is wasted and you cannot resize the datafile as the space is already allocated to a table.
Identify these kind of objects and then either you can use the SHRINK SPACE command or re create the object with
only required storage space.
If all the the objects are small, then you should be able to resize the datafiles using the RESIZE command.

Unable to extend temp segment by 128 in tablespace TEMP
Hi all,
I am using apps 11.5.10.2 and i think this is a database issue
ERROR at line 1:
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
Do i have to increase the tablespace, if so how to do it. I don't even know the EM Pass
Regards
Jaganwhat is the size of your temp tablespace?
Have another try, if the problem persists, increase the temp datafile size.
alter database tempfile <temp file name> resize <integer> M;
You can also add a new datafile.
ALTER TABLESPACE name ADD TEMPFILE 'filename.dbf' SIZE 10M;
You can always investigate and try to avoid too much sort by checking the SQL.

Wait Event Direct path read TEMP
HI,
I have two sessions waiting on wait event "DIECT PATH READ TEMP" (both the sessions with same SQL).Those sessions are almost in hung state.If i run that query from any other session,even that gets hanged.I have generated 10046 trace for these and found that all of them are waiting for a index object in TEMP datafile.
Has anyone of you had the same issue.
Please explain me what kind of action i have taken.
I have verified the stats..they are all up to date.
