• 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!

• Undo Tablespace and security of tenure in Oracle 9?

  Hello.
  
  I know that this option is available in 10g but I was wondering if it was also available in 9i? I'm guessing not because the column does not appear in the dba_tablespaces view, but thought I'd ask the experts here.
  
  Thanks for all the answers in advance.

  UNDO_RETENTION parameter was introduced in 9i, jointly with undo tablespace etc.
  Maintenance of the cancellation guarantee was introduced in 10g.

  Kind regards

• Problem with ASM and OMF Undo tablespace creation

  I'm trying to test installation using Automatic Storage Management and Oracle managed files database. I created ASM instance (+ ASM), disks and start (ASM_GRP01). I then tried the creation of database (ORCL) using this ASM instance. I also need to configure OMF to type no explicit localization files when creating table.
  
  I put in initORCL.ora
  
  UNDO_MANAGEMENT = AUTO
  undo_tablespace = undo_tbsp
  db_create_file_dest = + ASM_GRP01
  db_create_online_log_dest_1 = + ASM_GRP01
  db_recovery_file_dest = + ASM_GRP01
  
  so I ran the SCRIPT of CREATION of DATABASE:
  

  CREATE DATABASE ORCL
    USER SYS IDENTIFIED BY ***USER SYSTEM IDENTIFIED BY ***LOGFILE
      GROUP 1 SIZE 100M,
      GROUP 2 SIZE 100M

  When creating, checking its use on the instance of the ASM diskgroup, it pushes everything by creating the SYSTEM tablespace, but creating UNDO tablespace, I got an error. It's journal of creation of tablespaces to alert.log

  Hello..

  There is a spelling error in the parameter specification.

  undo_tablespace = undo_tbsp

  And

  UNDO TABLESPACE UDNO_TBSP DATAFILE SIZE 200 M AUTOEXTEND ON NEXT 20 M

  undo_tbsp in init.ora became UDNO_TBSP in create db statement. Fix and run, you will be able to create the DB.

• Undo tablespace filled with 95%

  Hi all
  
  We have R12.1 Instance with RDBMS 11.1.0.7.0.
  Undo table space here is got filled up to 95%, all the data files are not in AUTOEXTEND.
  
  In this case, I need to add a data file?
  If I add a file of data, is the performance database will be mediocre?
  
  Please suggest...
  
  
  Thank you

• 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.

• 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.

• UNDO Tablespace size

  Hello
  
  We have a production database with size 120 GB (DB Version 11.1.0.6), and our UNDO Tablespace size is 30 GB.
  
  For the last 4 days, the use of UNDO tablespace is more than 85%.
  
  We have disabled the AUTOEXTEND for the UNDO Tablespace.
  
  So that the UNDO RETENTION is calculated dynamically by Oracle itself and the value is now

• 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.

  Hello, I have a problem with Mozilla Firefox 14 and now also Firefox 15. When I click on .html files on my desktop, firefox will open a new window twice. Where is the problem? Thank you

  That may be a problem with the DDE.

  Try to undo and redo Firefox as default browser.
  
  Make a different browser like IE browser by default and then let Firefox do it again.

  Hello and welcome to the community!

  You can consider a charge of BONE, that something can be a problem with your OS BB given what you describe. But first, please try safe MODE:

  • KB17877 How to start a smartphone BlackBerry in Mode safe

  It will take several attempts to get the combination of keys ESC (press/release/hold) OK, so be patient. When properly in Safe Mode, run for awhile determine if behaviour will or will not return. If it is then in safe mode, then you should proceed with reloading the OS. But if the behavior does not work in safe MODE, then well... think about what happened just before this behavior started? A new application? An update? A theme? Something else? Think carefully that the slightest change can be causal... and try to undo all that was.

  To perform a reload of the OS, here are some process, you can use:

  At the top of each forum device, there should be some 'sticky' threads dealing with the level of the OS available for many models. If they understand your model, please use those as a reference as you go along. Otherwise, you will have to dig through the download portal official for packages of OS for your model:

  • http://us.BlackBerry.com/support/downloads/download_sites.jsp

  From a PC, you can install any compatible OS package (for example, for your BB model exact number) of a BB via this procedure:

  • http://supportforums.BlackBerry.com/T5/BlackBerry-device-software/how-to-reload-your-operating-syste...

  Note Although written to "recharge" and the storm, it can be used to upgrade, downgrade or recharge any BB device model - depends on the operating system package you download and install on your PC. If this OS package comes from one carrier other carrier for which your BB was built, then remove, on your PC, all copies of the SELLER. XML... There will be at least one and maybe 2, and they will be located in the same way or to (it changes based on your version of Windows) these files:

  • C:\Program Files (x 86) \Common Files\Research In Motion\AppLoader
  • C:\Users\(your Windows username) \AppData\Roaming\Research In Motion\BlackBerry\Loader XML

  Don't forget that you remove, since your PC, any other BB OS devices as packages with more than one installed on the PC can cause conflicts with this procedure.

  You can also study the use of BBSAK (bbsak.org) to perform the wipe what he is capable.

  You can also try this procedure might limit the specific causal element:

  1. Load your OS "bare bones"... If everything is optional, do not install it.
  2. If the behavior is immediately, then try another OS with step 1
  3. If the behavior does not immediately, then run for as long as necessary to make you to be sure that the behavior will not occur.
  4. Add one more thing - no matter how tempting, one.
  5. If the behavior does not immediately present, and then runs for long enough to be sure he won't have the same problem
  6. Repeat steps 4 and 5 until all things are responsible or the behavior presents

  When the behavior shows up, you know the culprit... the last thing you have loaded.

  If the behavior doesn't re-present, then you know that step 1 or 2 cured it.

  If the behavior has anything, then you have probably a problem of material level for which no amount of OS or software can heal.

  If you are on a MAC, you are limited to only your sanctioned carriers OS packages... but can still use any level they currently have to sanction. See this procedure:

  • KB19915 How to perform a clean reload of the smartphone BlackBerry using BlackBerry Desktop Software application software

  Good luck and let us know!

• Problems with error Windows Audio and Control Panel "one or more of the audio service is not running.

  I'm a bit of a technophobe, but I'll try to explain my problem, I got better.  I recently had a problem with Windows 8 and refreshed my system.  After refreshing, I installed AVG Anti-virus and that's where my problems really started.  After installing AVG I have no sound and my control panel usually pop up.  The box is displayed but there is nothing in it and it sorts just of sticks, frozen.  I tried the fixes recommended to fix my sound. The speaker in my taskbar icon has a red x on it and when I try to open it it goes right to the problem-solving mode, then comes up with "one or more of the audio service is not running.  When I try "run services.msc' and try to start Windows Audio through Services I get error 0x800706cc.  I tried to uninstall AVG and reboot, but it did make a difference.  Please help, this leads me to the madness now.  Nothing I try seems to work!

  Installation of AVG is when the problems started, I would start by undoing that.  Since the normal uninstall did not help, use system restore to return to a work situation.  Check here and use the #1 option.

  I have windows 8.1 64-bit oracle 12 c database.

  As you can see from the picture, there is problem with temporary space is available in the database. So, the question is how to extend using the sqlplus command line?

  Check if your default temporary tablespace is TEMP.

  using for example

  SELECT * FROM DATABASE_PROPERTIES where PROPERTY_NAME = 'DEFAULT_TEMP_TABLESPACE ';

  but be pro active and read articles about the TEMP tablespace.

  I guess you can resolve this problem if you see a page as

  TEMPORARY Tablespaces and TEMPFILES | Oracle FAQ

  Also give us the exact error messages and commands that cause those their.

  Let me guess a thing. It could be your program checks the available free space at TEMP and does not check if the TEMP is auto runs.

  So you must manually allocate the space required for TEMP.

• I have a problem with the path, what is? No effect applied, some new preset in Illustrator? I need to disable

  

  ferkomrkvicka,

  Two suggestions that may be too far:

  You can try to disable the GPU performance by clicking on the icon of the rocket in the bar of the App, or on the top of the menu bar, deselect the box Performance GPU; You may also uncheck performance GPU in your preferences. There are a few problems with the GPU and Adobe are working on them. They should be resolved with the 19.0.1 patch, but some are not. Link to 19.0.1 release notes:

  https://helpx.Adobe.com/Illustrator/KB/Illustrator-CC-2015-crash-bug-fixes-19-0-1.html

  Try to move or work assigned to scale (a little) and then Ctrl / Cmd + Z to undo, to get it in place. If usable, it is a roundabout way to use until the issue is resolved. or you can turn paste remembers layers in the layers panel, if you can live with the side effects.
