What Happens When UNDO Space Is Full / Transaction Takes More Time To ERROR
Jan 26, 2011
I have a long running transaction (more than 3 hours), and at the same time other operations are occurring on different tables, using the same UNDO space.
Sometimes we see ORA-30036, but this error occurs very late in the process. The transaction normally takes 3 hours, but when UNDO space is full, we do not get ORA-30036 upto 8 hours or 9 hours of process.
I am wondering what could be happening in the background, when UNDO space is full, which makes the transaction to extend upto 8 hours or 9 hours (pl. note, this transaction gets completed within 3 hours normally). This is in 11g, UNDO space is managed manually.
I am using oracle 9.2.0.8 on RHEL 4.8 (64-bit). I am facing a strange problem. I have this one job in database that takes almost 12-15 minutes to execute but when I execute procedure in that job manually, it executes in one minute. Even when no other job is running in database, it takes more than 10 minutes to execute.
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.

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

Worker process do it in background but it does not show in the front import log file (I dont understand why it not shows in the import logfile). it imports one table,one LOB , one LOB index ..then again one table,one LOB , one LOB index ... in this way .
And my observation first it inserts data into the LOB tables and then it inserts into normal table . And when it is starting to insert data to the normal table then this table's log are shown in the import logfile.
I am using Oracle 10.2.0.3. Since yesterday i am seeing a session with sid 1160 using undo tablespace but not able to find how much it is using .I need to know which session and from which module and how much is the Undo being used by those sessions. I have tried searching but all the queries provide me with some different results each time.
Also i need the same information for REDO being generated .
11.2.0.3 This is for a build. We are still in development. No risk of data loss. As part of the build, I drop the user,re-create it, re-create the objects. Allows us to test the build all the way through. Its our process. This user has some tables with several 1000 partitions. I ran a 10046 trace and oracle is using pl/sql to do loops to do DML against the data dictionary. Anyway to speed this up? I am going to turn off the recyclebin during the build and turn it back on. anything else I can do? Right now I just issue 'drop user cascade'. Part of is the weak hardware we have in the development/environment. Takes about 20 minutes just to run through this part of the script (the script has alot more pieces than this) and we do fairly frequent builds. I can't change the build process. My only option is to try to make this run a little faster.
But the query of import is still runing even not showing any amount of rows to be imported.
i already make the tablespace in which the table was previosuly before dropping but when i check the sapce of tablespace that is also not consuming one error i got preiviously while performing this task is:

i check streams_pool_size it will show zero and then i make it to 48M and after that
SQL> show parameter streams_pool_size; NAME TYPE VALUE ----------- streams_pool_size big integer 48M
regarding sizing undo tablespace and undo_retention parameter.we have to implement the database in production system with 40 users but how much space should be allocated to undo tablespace is there any propotions related to virtual memory and the parameter.i have gone thru oracle doc's and some related sites.its an ERP aplications that contains 20 modules .I am an new one to this dba level
i Cannot drop old undo tablespace. While dropping the old undo tablespace we get an error

i create this trigger to lock inserting transaction for any data greater than 30-04-2013 on a certain table
CREATE OR REPLACE TRIGGER INVALID_DATE_VALUE BEFORE INSERT or UPDATE on ra_cust FOR EACH ROW BEGIN IF :NEW.TRX_DATE >'30-APR-2013' THEN -- RAISE_APPLICATION_ERROR('ora-0000','DATE CANNOT FALL IN RANGE...Invalid Date'); RAISE_APPLICATION_ERROR(-20000, 'IT IS NOT ALLOWED TO INSET DATE VALUE GREATER THEN ''30-04-2013'''); END IF; END;
and this trigger created successfully
when i try to insert data in the table ra_cust even in a range less than 30-apr-2013
i got this error
ORA-20000: IT IS NOT ALLOWED TO INSET DATE VALUE GREATER THEN '30-04-2013' ORA-06512: at "ARASK_HAGAR.INVALID_DATE_VALUE", line 5 ORA-04088: error during execution of trigger 'ARASK_HAGAR.INVALID_DATE_VALUE'
While making a full db export i have got this error even though my export was completed with this warning. What should i need to do regarding to this error. My oracle version is 10.1.0.2 and Server is windows 2003.
Ideally we need to include description in tnsnames.ora but its taking time to contact DBA here. Hence we tried with this work around. The same is working fine if we are using sqlplus but sqlloader gives this error.

try to evaluate it as IMDB cache.I am facing this error repeatedly. I have increased perm size from 6.25 GB to 10 GB.After inserting about 460.000 rows I get the error again. Is it possible that 460.000 rows need 3.75 GB space?
In Oracle database these rows occupy about 200 MB space.
I need a stored proc that takes list of ids as input parameters. For all these Ids. the proc will send out data from another table as out ref cursor. Sounds very simple yet I am stuck with how do I pass the input list of ids.

The below query takes more than 30 minutes to return data.All the objects used are views. There is no direct reference to any table.The views with _mnth_ have data for 7 distinct months. The base table for all the views have a composite PK on the columns AR_ID (or ACCT_AR_ID),MSRMNT_PRD_ID
I need the order by, as the query is part of informatica code, and the order by works in the further processing.

Sysaux Tablespace is running low. WE SET AWR RETENTION TIME=60 DAYS. WE ARE NOT INTEREST TO EXTEND SYSAUX TABLESPACE SIZE. Usually we take AWR weekly once. Some times we did ADDM report and ASH.
CODEsql>select TABLESPACE_NAME, FILE_NAME, BYTES/(1024*1024), AUTOEXTENSIBLE, MAXBYTES/(1024*1024) from dba_data_files where tablespace_name = 'SYSAUX';
1. What's the best SOLUTION ? 2. Can i shrink sysaux tablespace ? 3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ? 4. What could be the reason for growth? Is there any way to free the space from sysaux table space?
I'm joinging two tables event_types and tmp_acc tables.
event_types contains 2 Billion records tmp_acc contains 20,000 records.
Resulting rows are about 300,000 records in event_types table end_t and account_obj_id0 are joined indexed
no indexs in tmp_acc.
When I run below query with nexted loop it takes 6 hrs to complete. But when I run with hash join even after 4 days it was still running. what is wrong with hash join here. Why it takes so long. I'm joining only 20000 rows. So I think there should be a way to get result rows quickly.
