PL/SQL :: Huge Disk Sort Causing Continuous Full Of Temporary Tablespace
Jan 2, 2013
We are facing problem as temporary tablespace getting full continuously. During below running query, temporary tablespace getting full continuously and now it is not managable so we had stop the processing but we need to resolve this issue as business impact is there.
MERGE INTO HDFCMPR.MPR_TB_MPRMASTER
USING (SELECT /*+ USE_HASH(A,B) FULL(A) FULL(B) */
MER_TRACKID, TRANID, DECODE (UCAF, 'n', NULL, UCAF) UCAF,
A.ID
[code]....
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
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).
how to find the root causes for temporary table space to grow unexpetedly and how to claim that grown space back automatically after the transaction over.
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.
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.
i have been trying to create a user with full access on default Tablespace so that i can access all the objects without any restrictions for the new user.
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>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 ?
i'm facing a problem while i'm inserting millions of record from table to table that undo tablespace reach 100% full and execution aborted. , how can free the undo tablespace ??? many of extendes are offline. will it flush automatically ??? or what i should do
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?
Why do export-import require temporary tablespace? Since export-import do behave like DMLs, when does temporary tablespace be needed by datapump utility?
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
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?
I am having past data in a table say for one year. each row is having a timestamp column. Now i need to calcute avg of data for every time interval betwwen start date and end date.
time interval can be in minute, hours, days or months..in case of hours,days and months , i need to convert to minutes and group based on that interval.
