• How to reduce the UNDO Tablespace

  Hello
  We had an UNDO Tablespace to 22 GB but it's using just 2GB. How to shrink the undo tablespace. We use the database in production cluster 3 node 10.2.0.4
  Is there is way we can worry about UNDO Tablespace or should I create an UNDO tablespace and assign the undo tablespace to DB and let fall the old CANCEL?
  How to ensure that the transactions are done and free to abandon the old CANCEL?
  That's what we must restart all three nodes each node has its own UNDO Tablespace.
  
  Need help on this issue.
  
  would appreciate your quick response.
  
  
  Thank you

  No you have not.

  Hello

  accrding to the temp of query operation is not necessary to listen to so.u can add just a data file with the correct measurement value I guess...

  Add more space should be sufficient (as mentioned earlier).

• Undo tablespace resize error

  The total space of the UNDO tablespace is: 3G and the space used for the tablespace UNDO is only 512M, so about 2.5 G space is free. But when I tried to resize the tablespace undo to 1 G, then its showing the error below:
  
  ORA-03297: file contains data beyond the requested value of RESIZING
  
  but the size of the data used is 512 M only.
  
  Kindly help me to resize the tablespace undo to 1 G.

  Please suggest.
  
  
  Thanks in advance!

  You cannot resize the undo tablespace. If you try to reduce the size.
  Then add that a tablespace unod can like undotbs2 then set undotbs2 as a default value in your database. Then, slide the previous undo tablespace

  You can find the location of the location of the storage space using the command
  Select * from DBA_DATA_FILES

  You must log in as system administrator...

  You can use the ALTER TABLESPACE command to increase the size of the storage space...

• It will frequently commit resolve ora-30036 (cannot extend the undo tablespace)

  I use 11.2.0.3 database. I confused on the use of validation to resolve ora-30036.

  I have the script in migration once that has many updates and I'm getting ORA-30036 (unable to extend segment by 4 in the "UNDOTBS" undo tablespace) .

  Our undo tablespace in NO mode autoextend and like this is just a one time event, we will not increase it.   He is currently 6 GB.

  We would commit determination ORA-30036 in my case? If not why? Is there a better solution to solve it.

  
  

  When I say commit frequent, I won't commit after each line, I just want to commit after may be million lines, so that my active cancellation extend turn into cancellation remaining will extend and Oracle will be able to use it in case of pressure of space.

  
  

  Note:

  UNDO_MANAGEMENT: AUTO

  UNDO_RETENTION: 2700

  Undo tablespace retention is NOGAURANTEE.

  Why don't you increase it?

  You must use the correct size of UNDO necessary for the work that will be done.

  A lot of shops to create a for big lots new UNDO tablespace and then switch to it for batch processing. Once the task is completed, they switch back to the normal UNDO. That prevents the normal RETURN of autoextending far where it is normally necessary:

  ALTER SYSTEM SET UNDO_TABLESPACE

• Undo tablespace full

  Hi all
  
  OS: Solaris
  DB: 10 G
  
  My undotablespace had a lot, I should directly resize it or is there something else I should do first?
  One last thing, if I take the bounce of the database, this will affect cancel it?
  
  Kind regards
  Sphinx

  If you have room for an other undo tablespace, why not make one you have more? Don't forget, one will not be removed until all transactions using this are made.

  There are a few reasons you may need more to cancel the space: you have people leaving the open sessions, you have poor code that uses too or shot himself in the foot, stand too close, autoextend to cancel gourmand or you really need the space.

  Tom Kyte has recommended to keep enough space around it for annual transactions of large batch if you have those. Unfortunately, this means that you do not have the other stuff stupid user. I take an intermediate point of view, keeping a great cancel (it is about half of my db), even though it is barely used most of the time and kill sessions where I can determine that they should not be left open (in other words, people who rarely run stuff from one day to the next day to ask, since most people don't).

  What are the exact errors are you seeing? If this is the code that self-destructs in the foot, no matter how cancel it y a. search for ora-1555 on asktom if that's what you see. What's your retention, what is your guarantee?

• extending undo tablespace

  Hello world!
  
  I used this sql to check the status of my storage space.
  

  SELECT /* + RULE */  df.tablespace_name "Tablespace",
         df.bytes / (1024 * 1024) "Size (MB)",
         SUM(fs.bytes) / (1024 * 1024) "Free (MB)",
         Nvl(Round(SUM(fs.bytes) * 100 / df.bytes),1) "% Free",
         Round((df.bytes - SUM(fs.bytes)) * 100 / df.bytes) "% Used"
    FROM dba_free_space fs,
         (SELECT tablespace_name,SUM(bytes) bytes
            FROM dba_data_files
           GROUP BY tablespace_name) df
   WHERE fs.tablespace_name (+)  = df.tablespace_name
   GROUP BY df.tablespace_name,df.bytes
  UNION ALL
  SELECT /* + RULE */ df.tablespace_name tspace,
         fs.bytes / (1024 * 1024),
         SUM(df.bytes_free) / (1024 * 1024),
         Nvl(Round((SUM(fs.bytes) - df.bytes_used) * 100 / fs.bytes), 1),
         Round((SUM(fs.bytes) - df.bytes_free) * 100 / fs.bytes)

   WHERE fs.tablespace_name (+)  = df.tablespace_name
   GROUP BY df.tablespace_name,fs.bytes,df.bytes_free,df.bytes_used
  ORDER BY 4 DESC;

  It shows that my undo tablespace has only 3% of space left.
  
  I simply run this SQL command, but the result is always the same.
  

  SQL> alter database datafile 'c:\ORACLE\DATA\PRODUCTION\DATAFILE\O1_MF_UNDO.DBF' autoextend on maxsize 50M;
  
  Database altered.

  I mistakenly thought that the size of the existing file is less than 50 M.
  
  But then, realized the unused (3%) is 50 M.
  
  How can I increase the size of the file now.
  
  Please guide me.
  
  The command that I published will have a negative impact?
  
  Thanks in advance.

  Hello

  What is your current undo tablespace now?
  You can use the ALTER DATABASE statement. DATAFILE statement to resize or extend a data file
  you issue this:

  SQL > alter database datafile ' c:\ORACLE\DATA\PRODUCTION\DATAFILE\O1_MF_UNDO. DBF' autoextend on maxsize 50 M;

  If it stops when it reaches 50 m.

  You can try below:

  SQL > alter database datafile ' c:\ORACLE\DATA\PRODUCTION\DATAFILE\O1_MF_UNDO. DBF' autoextend on next 1 m maxsize unlimited;

  You must set the maxsize value according to your availability of storage.

• laptop computer (HDD 320GB) with windows 7-64 bit OS.iam unable to shrink the drive c less than 155 GB

  Hello Sir,

  recently I bought the laptop (320GB hard drive) with windows 7-64 bit OS.iam unable to shrink less than 155 GB c drive please help me. I want to reduce this to 90 GB

  Its also the case that win7 takes only supported 4 basic partitions and you can't mention what Disk Management displays for drive 0.

  And also if a pre-installed version of victory, if you manage to create partitions and at a later date, you will need to use your recovery disks, that may well destroy all created partitions.

  For what reason you want to partition?

• Transaction is written to the log file and it is not written to undo tablespace. During a failure of the system how oracle rolls back the transaction.

  Hi all

  My question is:

  Transaction is written to the log file and it is not written to undo tablespace.

  During a failure of the system how oracle rolls back the transaction.

  I have already provided the answer, you ignored if well (you seem to only read the responses by people of your country).

  Redo log is always written * first * before * writing to the data block (redo log writing is much more aggressive). So it DOESN 'T MATTER if you lose these scriptures of rollback segment.

  Valuation: rear roller followed by roll forward, using redo log files and/or archive redo log files.

• How to UNDO tablespace size?

  As legend. Thank you!

  An UNDO tablespace sizing requires three data items.

  (UR) UNDO_RETENTION in seconds
  (UPS) Number of undo the blocks of data generated per second
  (DBS) Overhead varies on position and size of the file (db_block_size)

  The necessary cancellation space is calculated as:

  UndoSpace = HEART * (UPS * DBS)

  read the Doc ID 262066.1 it has retail formula.
