• Question about Undo Tablespace?

  Hello;
  
  The necessary size of the undo tablespace is the number and size of the transactions that occur on the database. But I do not need to interview one of these transactions for a schema or table using flashback it is a way to disable transactions writing on a table or schema of undo tablespace?

  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.

• 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.

• Need information on objects not expired undo tablespace

  We are facing a problem in our database for 3-4 days.

  The objects remaining in the database increases day after day. As our ts cancel autoextend enabled, it increases the storage space.

  Currently the following is the scenario.

  SQL > SELECT DISTINCT STATUS, SUM (BYTES) / 1024/1024/1024 GB, COUNT (*)

  2 GROUP OF DBA_UNDO_EXTENTS BY THE STATE;

  STATUS GO COUNT (*)

  --------- ---------- ----------

  61.5925903 10995 REST TO RUN

  3.33197021 356 EXPIRED

  ACTIVE 18.478515625

  Thus, the remaining data 61GB while active is only 478 MB and expired is 3.3 GB.

  My questions are

  1. How can I check the object or sql query or a program that contains the data to cancel "RUN" so. How can I find the names of these objects?

  2. If I turned off autoextend undo ts if this solves the problem and take the new space to cancel from space to cancel remaining?

  Help, please.

  1. the UNEXPIRED is not bound to a query, but the UNDO for UNDO Tablespace retention period. And the Undo retention is a value set automatically when the parameter UNDO_RETENTION is minium.

  The Oracle Documentation says:

  For an undo tablespace with the AUTOEXTEND option is enabled, the database tries to honor the specified minimum retention period by UNDO_RETENTION . 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.

  2. Yes this will fix the issue that now the calcution for UNDO retention is different.

• MAX limit for segment undo undo tablespace

  Hello Experts;
  
  Where tick No, max of segments of cancellation in the Oracle database?
  

  Is limited and depends on the SIZE of the DB or UNDO tablespace size?

  Thanks in advance...

  What?

  dba_data_files - I thought that from here we can not get undo_segments County!

  not serious... Thank you...

  You started this thread, ask questions about the size of UNDO limit; which is a direct function of DBA_DATA_FILES.

  Then you changed question about County segment UNDO. which is a direct function of DBA_SEGMENTS.

  so take your decisions about what question should be answered.

• UNDO TABLESPACE MANAGEMENT

  Hello
  I'm trying to remove 90 columns of a partitioned table big. I was trying a physical decline first and since it takes more time, I decided take unused columns and drop them. However, I could put in unused condition.
  Now I'm trying to drop these unused columns in the table, it has run for 22hours approx. I'm keep increasing the undo tablespace to store the undo data.
  I have also diminished the undo_retention at 300 to 900.
  
  My question is there a better way to drop these columns. And is it possible to flush out the undo data.
  
  Your valuable response is greatly apprecaited.

• Undo tablespace is used

  Hello
  
  I have a database that was created in the CARS and was converted into standalone sometime some time. There are always 2 Undo tablespace on this database. In looking at dba_undo_extents, we have first active, expired and Unexpired extensions. But second one only expired scopes. I think that the second is not used since DB has been converted, but I'm not sure. How can I tell how old are extended in this tablespace?

• Undo tablespace is enough for the declaration of a deletion

  Oracle 9.2. We need more than 140K delete records from a table. If I use just a statement
  "delete from tablename where xxxx"; and then commit; It will remove 140K records in a statement. My question is if my UNDO tablespace is sufficient for the removal of these many records? My undo tablespace has total maxbytes = 35G and
  user_bytes = 12G. CanGrow.
  
  My table avg_row_len = 119, so 140 x 119 = 16 K M. Undo tablespace is enough to remove 14oK in a statement.
  
  My analysis is correct? a better idea?
  
  I don't want the deletion failed because of not enough undo tablespace.
  
  Thanks for any advice.

• Hardware blackBerry Smartphones Dumb newbie question! :)

  Hi people,

  I'm new in the world of the blackberry and I'm about to take the plunge with a unlocked sim-free BB Bold to use in the United Kingdom on Vodafone. I read on the differences of software between BIS and BES and would go for a set - up BIS. My dumb newbie question is equipment arrives in version BES or BIS or not?

  Thanks in advance and do not hesitate to make fun of my madness

  craigdh wrote:

  Good answer Xandrex. However I'm still not clear as to the issue of equipment, I asked. The reason why I am wanting to buy "BOLD" a separate contract is.

  1. it will work a little cheaper over the life of a contract.

  2. I will get my "BOLD" much faster.

  3 UK networks have a reputation for crippling features in high-end etc phones then charge you more to get similar functionality via one of their services.

  4. they are very slow to provide updates of the firmware on their own brand of appliances.

  There was a little insinuation in my answer: basically, you buy a mobile phone, so you get a BIS/BES contract with a carrier who takes in charge that the mobile phone. A "BOLD" can be used like BIS or BES, it depends on the company.

  On the price, I'm sure the phone deal + contract is always cheaper than a "BOLD" (retail and not eBay from some guys) then a contract which is usable (that is, no GoDaddy or 0.01GBP / KB).

  for the speed, you are the one who knows.

  The thing of the cripping: the thing is, the updates are provided only by the suppliers (they get a barebone RIM OS, then add their stuff like facebook or AOL). Even if you buy a single "BOLD" without a contract, if you want to upgrade the regular way, you wait fot your carrier to publish the upgrade. Or you can do the regularly (which can be made with or without the purchase contract at the same time).

• 2 blackBerry Smartphones newbie questions: do I need it, and how I spoil my phone?

  Sorry for the newbie questions:

  My IT has already set up my phone to receive email from their Blackberry Enterprise Server.

  (1) do I still need to install the desktop software?  Given that I can transfer files via Bluetooth from my laptop and my contacts/calendar/notes are stored on the Exchange Server, is there any point?

  (2) if I do not need to install it, given that my email is already working with BES, and the Office installation configures email settings, how do I keep the new Desktop install to mess up the current configuration of e-mail?

  Of all the notes of support on the software, looks like more trouble whereas at this stage.  I really need to treat it?

  Thank you.

  There is not much need of DTM, but it is convenient to update the OS of your BB. Sometimes there will be releases of minor bugs corrections and such to your BB - DTM will be meaningless and install them, while updating wireless could not detect them. For a major OS update, you want DTM, as it will do a backup/complete restoration of your BB, including configuration settings, and others so that you don't have to redo those. But, to your e-mail, calendar, contacts, etc. - you are right, it is useless given that your Exchange Server is actually your master with your BB being actually a backup of that (in a sense).

  In addition, USB drivers (which are part of the package DTM) are necessary in order to charge your BB via your laptop USB. You can download and install all the USB drivers if this is the only part of the DTM you want.

  When you install it, it will ask if you are in a company - say Yes and it will install properly. Installation when your PC is connected to your corporate network and your Outlook is open. Who will get the best and fastest configuration. When you install, do not let it select the functions of auto-launch... If you wish, attach your BB and manually run the DTM.

  Basically, on the whole, I vote 'YES'. You get the USB charging. You can save if you wish. You get the device OS and other updates. Most of the reported problems are people using it to synchronize via USB things - you won't do that because most of your stuff will be syncing via BES OTA. Other things, you can simply drag-and - drop (music, videos, etc.). .. .follow these instructions (use the latest 5.0 DTM):

  Good, please excuse my ignorance... guys xD

  I just bought two s BlackBerry Curve 8530 from Sprint. I'm pretty tech savvy, but there are some things about this phone, I can just enter in two or three days I got em:

  Deleting photos: Well, then I'm in my media folder, in the images. I selects a photo and press the BlackBerry button and select Delete. Then he said: it is read-only, and when I remove it, the icon is still there. I tried to turn on/off the device, and it's still there. Thought this one myself. I plugged it up to the Desktop Manager and all of a sudden all the photos I had taken appeared. I was also able to delete using the "BlackBerry" button and then "delete". It doesn't give me that read this option.

  Saving images: So, for some reason I can't save more photos. I don't know even how I saved the first 12 photos I have taken... but now it won't save any more. What the hell happened? xD I have a 2GB card in my phone... surely these 12 images didn't fill in this card... Thought this one myself. I plugged it up to the Desktop Manager and all of a sudden all the photos I had taken appeared.

  Buy ringtones: On my old phone LG, I used to buy ringtones RealTone Jukebox... where they had extracted from songs that I could download for a crazyhigh. Where can I buy the real music ringtones for BlackBerry? What I do myself?

  Media moving to my PC?: I went through the music store of Sprint comes with my camera, and two purchased songs. I want to know if I can get these songs out of my BlackBerry smart phone and my PC. Also, if anyone knows what format they are in (if they bought before Sprint music store).

  To buy another memory card: Where the best place to buy one of these mini memory cards? One of my friends like, a 24 a concert... and I currently have a 2 gig (who, I should mention, is more fricken memory I have in the computer I do not write about this time xD) how can I find out if the card is compatible with my camera?

  WTF @ Redlight?: From time to time (we can always do that, I'm not sure), the little red light at the top of my unit starts to blink even if I do not have a weak battery or not new messages. It first happened lastnight when a friend sent me 3 IMs at once. I had to reboot my device and I think that he is stopped. Earlier, it happened again (I had several new messages) and this time whenever my display is on, the light was red only flashes do not. It can always be like this now, but I'm not sure. My camera is in the other room and I'm too lazy to check xD. Why would he do that? How can I get him to stop?

  Turn off the sound of the camera?: My camera makes the shutter of the camera, even when noise silence. Is there a way to stop this?

  
  

  Auto keyguard: I have EPIC hand-dial to people purse. In my view, it has a keyboard lock button in the dashboard of BlackBerry (that is the correct term for this?) But I want to get to the place where the keyboard auto-lock after a certain period of time. Is this possible? I saw somewhere about pressing the button mute will lock it... who is the top/center of the unit button?

  Key blackBerry?: Well, don't laugh, I know that I'm retarded. But, the key to the left of the beach towel... than the devil who called? He got the BlackBerry logo on it... is what he called the BlackBerry button? I know, I know, I'm retarded and could probably flip through the manual to figure it out... but still. I might as well ask now xD

  
  

  Choose the icons to display on the main screen: When I added an e-mail address, he put an icon on my main desktop, in the row of icons at the bottom of the screen. (where is my background image and all that). Can we choose the icons that we want to display on the main screen? I have really now, my calendar icon that I know that I use. I'd love to move the keyboard lock button here though... is it possible?

  Speaker?: How can I get speaker? xD

  Theme Studio (software, no associated device): Anyone used this? It is quite easy to use? I am tech savvy, but I don't want to just download a ton of programs on my PC that I won't use xD I'm working on the Desktop Manager and it takes forever. I want to make themes, but I'm curious to know how easy to use this program is... graduate to use design or if it would take a graph xD

  There may be an icon on the home screen of your camera to buy ringtones. Or you can open the browser and go to http://mobile.blackberry.com. There is a link of ringtones that you can click

  It is recommended to buy a microSD card to store your multimedia files, if you run out of memory on your device.

  
  

  Depending on what OS is your BlackBerry tells you what size you can buy a microSD card. You can check under Options | Topic (will appear as v4.xx.xxx). Look at the table on the following link to see what size you can get - http://www.blackberry.com/btsc/KB05461

  
  

  On the BlackBerry, go to Options | Media Media Card recommended parameters are:

  
  

  Media card support: WE

  Encryption mode: NO

  Mass storage support: WE

  Auto enable mass storage Mode when connected: YES

  
  

  Mass storage mode allows your BlackBerry to act as an extra drive when it is connected to your PC. It will appear as an extra drive letter in Windows Explorer. So you can just drag/release the multimedia files on your memory card

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

  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.

  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.

  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
