• 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:

  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:

• Question about Undo Tablespace?

  Hello;

  OK, it's fine, so what makes you say you build too UNDO? What is the problem you're trying to solve? Or you want to know if you could get back to CANCEL in writing?

  Our log tables generate too much to cancel because we need you connecting all these data (insert and update for the most part)... but we don't care about these log tables, we want to reduce the cancellation written for these tables logs so that we could use more flashback query timestamp older due to more space in the undo tablespace...

  I think I mentioned in my other two answers above that it is not possible to disable the generation of the cancellation, or at least I don't know that there is no way to do it! What you can do, if you are worried about the Undo tablespace grows, it is that make you a tablespace size Undo fixed by controlling the Undo data that are generated. You can use Cancel Advisor of the to do. With the Undo retention period of your proposed, she would like the size of the Undo tablespace tips and you can add about 20-30% extra size and you should be fine. But as I've already said too much, he has No way to stop generating cancellation.

• Why import data if ready schema and index create, increase in Undo TableSpace

  I have a problem importing data.
  When I export data don't have schema import include the index schema.
  And then I import the schema ready.
  When I import data, I find this Undo TableSpace increase very fast.
  I have therefore two tests.
  1. IMPORT of data and index, every thing ok look
  2 import a schema includes index
  and then import data. Undo Tablespace very rapid increase

  If you mean undo tablespace increase in order to read consisten read.

  N ° cancel space use increases due to the DML. (requests for consistent readings read undo, they generate no cancellation to grow)

  so you're saying that redo log appear, rollback undo segment will increase.

  N ° increase in written cancellations results increase in roll forward.

  IF we import large data, we must export data with the index and import data right now

  If you import large data, you must create the indexes after the data is imported. If the index definitions are included in the export, the default behavior is that import will create them once the data is imported. To do this, undo lower for indexes.
  Note This will generate redo for the creation (but does not cancel and therefore not generate recovery for cancellation). You can avoid this by manually running CREATE INDEX... NOLOGGING - but it means you need to get and modify the scripts CREATE INDEX.

• Problems with UNDO tablespace

  Hello
  
  DB_VERSION: 10.2.0.4

  SQL > show Cancel parameter
  
  VALUE OF TYPE NAME
  ------------------------------------ ----------- ----------------
  UNDO_MANAGEMENT string AUTO
  UNDO_RETENTION integer 900
  undo_tablespace string UNDOTBS1
  
  I know that UNDO tablespace stores the old image of o / old value when the cancellation of the user, the old value is returned to the user throgh UNDO.
  
  
  My UNDO tablespace grows up to 24GO as a developer frequently updates the database in the morning and in the evening.
  
  Basically, it runs a script to offset that includes the INSERT and UPDATE and it is important to extermely.
  
  Whenever the UNDO SCT is full, I create a new one with autoextend on, what happens if I do not autoextend?
  
  1. what would be the impact on queries, if I do like above I always created UNDO tablespace with autoextend 2Go on.
  
  2. What is the best time to drop the old UNDO tablespace?
  
  Thanks in advance.

  Dear user12000301,

  Firstly the undo tablespace is not just there to roll back the transaction. You can use the for recovery undo tablespace (roll back during the recovery of the instance), coherent reading and also for operations of blowback.

  If you have defined a tablespace undo with the goal of conservation of 15 minutes, but have fixed size then;

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14231/undo.htm

  +"+
  + The following points explain the exact impact of the undo retention UNDO_RETENTION parameter: +.

  + The UNDO_RETENTION parameter is ignored for a fixed size undo tablespace. The database can overwrite the information to cancel remaining when the tablespace space becomes low. +

  + For a tablespace undo with the option enabled AUTOEXTEND, the database tries to honor the minimum retention specified by UNDO_RETENTION period. When space is low, instead of crushing the cancellation information remaining, the self-aggrandizing tablespace' extends. If the MAXSIZE clause is specified for an auto-croissant undo tablespace when the maximum size is reached, the database can begin to replace the cancellation information remaining. +
  +"+

  Be careful with the settings to cancel it. The size, before you add the new data files in the tablespace, undo or autoextending for your pain, you must consider the DML that caused the growing undo tablespace. Necessaryly should generate redo or cancel? If so, know the total amount of undo blocks through the relevant DML.

  If you have created a with 2 GB undo tablespace and mark as CanGrow that the data file can be up to 32 GB. The DBCA you will create a petit_fichier undo tablespace but you can create another like bigfile and pretend the tablespace default undo for the operation.

  The best time to drop an undo tablespace is to wait at least undo_retention period of time has elapsed to make sure you don't need to have the copy of the coherent image transactions are committed. I think that the solution could be achieved as underlined Chinar but be careful on the active rollback segments in your database. You can also dynamically change the default undo tablespace anytime if the database uses the spfile.

  Hope that helps.

• 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.

  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

• 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.

• undo_segments in the undo tablespace

  (1) at least how undo_segments in undo tablespace?

  Is optimal?
  If I increase the size of the undo tablespace, undo_segments counts also have increased!

  Version of DB is 10g

  Hello

   

  The two time oracle maintains exactly 10 segments. (you can see nom_segment begins by _SYSSMU11)

  I'm not clear on what exactly 10 segments. I have undo tablespace of ~ 250 GB with 6676 stored in dba_rollback_segs.

  3) why undo tablespace with the only spaceMo 46,8125 '?

  
  

  (4) I mean why he is stiil 450Mo undo_retention even through time or same validation has occurred?

  Just Oracle - Doc

  Once a transaction is committed, the undo data are more necessary for purposes of recovery rollback or transaction. However, for consistent read purposes, long-running queries may require old undo information to produce older images of data blocks. In addition, the success of several Oracle Flashback features can also depend on the availability of the old cancellation information. For these reasons, it is desirable to keep the old information of cancellation for as long as possible.

  Introduction to the management of the automatic cancellation

  With undo tablespace, you would see extended with the status ACTIVE, EXPIRED, extents still to RUN.

  Active cancellation extended are used by transactions and will be always active, because they are needed for the restoration.

  Extensions has expired are not used by transactions, the data contained in these extended is committed and the time UNDO_RETENTION is passed, so it is not necessary for the coherence of reading and can be reused.

  Not expired extensions are extended no assets but honor UNDO_RETENTION. Transactions belonging to these bodies of cancellation are determined, but the retention time has failed, and it may be necessary for the coherence of reading!

  Paste the query result - below

• I use Lightroom 4.4 on windows 8. Less than 500 photos on the catalog and the catalog size is currently at 2.16 GB. Lightroom works fine, but I'm taking a risk by leaving the catalog to grow beyond 2 GB?

  I use Lightroom 4.4 on windows 8. If I have less than 500 photos on the catalog, I do a lot of alterations and cleaning of the images and therefore the size of the catalogue is currently at 2.16 GB. Lightroom works fine, but I'm taking a risk by leaving the catalog to grow beyond 2 GB? Should I close it and start a new catalog? Thanks for your suggestions.

  Many local adjustments (brush strokes, spot healing) can have a huge impact on the overall size of the catalog because they are all saved as stages of the individual history and so I wouldn't worry - there is nothing wrong with your catalog. See my thread here since a few years back: which affects the size of the Lightroom catalog file? where Rob Cole usefully thought of it for me.

  You could delete the history if you wanted and that I'd be willing to bet that the size would be reduced considerably. That said, my catalog file is larger than 10 GB (as I do a lot of local changes as stated in the thread I linked to) and it causes no problem at all, apart from resulting in a backup of slow catalogue (my previews resume another 30 GB or more). I have not yet felt the need for the history of the Reformation, but doing so probably would increase my catalog to about 1 GB, so it's an option if size becomes a problem for me.

  My advice: continue anyway and don't worry in this regard.
