What is the reason, and It is saying that temporary tablespace is empty ( temp tablespace have almost free space ) why it is saying like that? And users default temp tablespace is that tablespace only ( database have only on temp tablespace

We have EBS database with version 11.1.0.7 . Our tablespace is not releasing space ,as the below query show that TEM2 is using only 3 g .
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_freeFROM 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 ) DWHERE A.tablespace_name = D.nameGROUP by A.tablespace_name,

I have a requirement to get create a separate temporary tablespace for application user, the tablespace name is OPC_TEMP on Oracle 11g. During the application installation we are expecting this tablespace to show up under the user_tablespaces but it doesn't. When I tried to check with the DBA, they mentioned that it is possible for this tablespace to be listed under the user_tablespaces because to have this, the quota has to be assigned to the tablespace and it is not possible to assign quota to temporary tablespace on oracle 10.2 and above due to certain limitation (oracle metalink ID 331657.1).

When we are using pga_aggregate_target and sort area is automatically managed by Oracle. Why oracle is not allowing for auto allocating extents in TEMP and still extents of uniform size of 1 MB is used.

I tried to create an index on a large volume table(approx 9 GB) and I got the below error message:-
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
The size of our TEMP tablespace is 3GB and currently it is showing as full.
This tablespace is locally managed and we are not running any other operation on this test database at the moment.
We need to delete data from this table based on a column value, so I was planning to create an index on that column.
I saw on the net that one of the proposed solution is :-
alter tablespace TEMP default storage (pctincrease 1);
alter tablespace TEMP default storage (pctincrease 0);
alter tablespace TEMP coalesce;
but it was mentioned that this does not work with Locally Managed Tablespaces.
We are currently using Oracle 9.2.0.7.0 production release installed on Linux platform(Linux 2.6.9-89.0.25.ELsmp #1 SMP i686 i686 i386 GNU/Linux)
I increased the size of TEMP tablespace to 12 GB but the index creation still failed with the same error.

What should be our approach when we see the disk response time is bad for a particular tablespace in database.I heard a good disk response time should be on an average 10ms.

on my 11.2 DB comes from time to time to situation that the temp tablespace runs full. It longs for only couple of seconds and when the dba notice it, the tablespace is already almost empty. Is it a way somehow to create like a "callback-notifier" that fires f.e. when temp tablespace is for let's say 70% full. That "callback-notifier" will run the sql-statement to look in v$session, v$sort_usage, v$process, v$parameter for the problem sessions.

If my tablespace goes beyond 80% I should get a email from Unix crontab.
1)Warning for tablespace 80% full.
2)critical for tablespace 90%full..
I need the script for Oracle tablespace with 87% and shell script.
Do I need 2 scripts? Is there anything ready available (Oracle 10g).

we have a situation where both undo tablespaces were almost filled i.e UNDOTBS1 99% and UNDOTBS2 100% filled so i add data files to it and then i found a lot of blocking session and was just killing them through EM then i stop my front end listener and also down the service, now i don't have any blocking session but on EM a big WAIT is coming. alert log shows nothing serious, it was showing deadlock but now it is over as well.

Tablespace usage alerts are checked every ten minutes. You can request a check every minute when you set the threshold, and confirm that this has been set:
orclz> execute DBMS_SERVER_ALERT.SET_THRESHOLD(-
> metrics_id => DBMS_SERVER_ALERT.TABLESPACE_PCT_FULL,-
> warning_operator => DBMS_SERVER_ALERT.OPERATOR_GT,-
> warning_value => '50',-
> critical_operator => DBMS_SERVER_ALERT.OPERATOR_GT,-
> critical_value => '75',-
[code]....
orclz>but you will still have to wait up to ten minutes for the alert to be raised. know whether this frequency can be changed? And why this particular alert behaves differently from all the others? This is the bahaviour in all releases since server alerts arrived.

We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?

We have a Production Oracle 10g R2 RAC on HP-UX v2 IA64 servers.We have Two Disk Groups one for Archive (ARC_DISK - 100 GB) and other for Database(DATA_DISK - 1 TB]. We wanted to add more space to the DATA_DISK disk group.Unix admin configured 200 GB from SAN and changed the ownership of the Disk to oracle and permissions to 775 on 1st Node.I opended DBCA from 1st Node and was able to see the disk in 'Show Candidate'.
I added this disk to the DATA_DISK disk group and clicked OK but got ORA- error with some message like some operations could not be performed. I exited DBCA.We realized that we had forgotten to change the ownerhip and permission from the 2nd Node.Unix admin changed the ownership of the Disk to oracle and permissions to 775 on the 2nd Node.
I opened DBCA again from 1st Node and selected the DATA_DISK disk group but could not find the Disk in 'Show Candiate' open. I clicked on 'Show All' and this disk was shown with Header_Status - MEMBER but not allocated to DATA_DISKGROUP. When I clicked the 'Show Member' option, this disk is not shown for DATA_DISK disk group. I exited DBCA at this point.As this is a critcal Production database I didnt proceed any further and exited DBCA.
Now I need to add this Disk to the DATA_DISK disk group but not sure which option to select. I got one reply from another forum to run DBCA select the DATA_DISK Disk Group and then click 'Show All' and select this Disk (which already has MEMBER as Header Status) and select Force Option and click OK to continue.

I Configured an ASM instance and a disk group with two disk for normal redundancy.
> Here .. each disk is 2gb
The disk group has two disks...
SQL> select group_number, name, type, total_mb, free_mb
2 from v$asm_diskgroup;
GROUP_NUMBER NAME TYPE TOTAL_MB FREE_MB
------------ ------------------------------ ------ ---------- ----------
1 DATA NORMAL 4000 3898
as the group has two way mirroring (Normal redundancy) How much data (2 GB or 4 GB) can i keep in the disk group? My conception is I can keep 2 GB data in the disk group... (as the disk group keeps every extent in another disk as mirror)

I have 2 servers both having windows server 2008 64 bit as operating system installed on both I need to install oracle clusterware 11g r1 on both servers with clustering on external storage. I have configured the network(private,public and virtual) for both servers and have started the installation.
In the installation of oracle I add both servers but then I reach to a point where they ask me for voting disk or ocr disk in the cluster configuration storage but no disk is present how can i create ocr disk or voting disk on windows server 2008? And the external storage should I buy a special type of storage that supports clustering to continue my work?

I'm looking for a way to get continuous dates as a period in the result.My tabledata contains a date and a status, I want to get continuous dates with the same status value.
That's my tabledata:
select * from (
select to_date('01022012', 'ddmmyyyy') as thedate, 1 as status from dual
union select to_date('02022012', 'ddmmyyyy') as thedate, 1 as status from dual
union select to_date('03022012', 'ddmmyyyy') as thedate, 2 as status from dual
[code]...
THEDATE STATUS
---------- ------
01.02.2012 1
02.02.2012 1
03.02.2012 2
04.02.2012 1
05.02.2012 1
[code]...
And that's the result I am looking for:
select * from (
select to_date('01022012', 'ddmmyyyy') as startdate,
to_date('02022012', 'ddmmyyyy') as enddate from dual
union select to_date('04022012', 'ddmmyyyy') as startdate,

I have in my database table 2 important date columns: StartDate (Not null) and EndDate(Allowed Null).I want to ensure that all records in the table would always create perfect contiues date ranges with no holes inside.Wor example there may not be records [1-may..1-may, 3-may-...] because there would be a hole [2-may...2-may]. Holes are not allowed.
And overlapping is not allowed, for example [1-may..1-may, 1-may-2may, 3-may-...] is not allowed because overlapping occures on day 1-may. Overlapping and holes are not allowed. But it is allowed that table has no records at all. But all DML manipulations with existing records must ensure that overlapping and holes won't occur.How to write such check? How to ensure that data ranges would stay continous with no holes and no overlaps?
