Create the State of Mount, possible undo tablespace?

• Need help created the state machine which is based

  I need assistance with my labview program. My goal is to write a program that allows the user to activate a switch. When they do this, it will start a loop witch goes on a digital switch for 45 minutes and then 30 seconds and so on until the user did switch the switch off. The time doesn't have to be precise. I use the NI 9476 digital output card.

  I wrote the code to activate the on/off switch. I know add fuction in loop for 45 minutes a stop 30 seconds. I guess that the most effective method would be to use a state machine, but I struggle to understand.

  The program that I wrote so far without loops is attached.

  Thank you

• 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!

• 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.

  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:

• Is it possible to have three Undo tablespace for a 2 RAC node?

  Version: 11.2.0.2/RHEL 5.4
  
  I was under the impression that you need only one UNDO Tablespace for each instance. But, for our 2 bow TIE, I see three Undo tablespace. No idea what is the third for?
  

  SQL> select tablespace_name,status from dba_tablespaces where CONTENTS = 'UNDO';
  
  TABLESPACE_NAME                STATUS
  ------------------------------ ---------
  UNDOTBS1                       ONLINE
  UNDOTBS2                       ONLINE
  UNDOTBS3                       ONLINE
  
  SQL> select distinct inst_id from gv$session;

  ----------
           1
           2
  
  
  $ olsnodes -n
  thclst214   1
  thclst215   2

  I think it's possible, but a database instance is not able to use an undo tablespace. It is probably an error and you can try to drop the tablespace is not in the GV$ PARAMETER.

  I ran the following on a 2 RAC 11.2.0.1 running node:

  SQL>  select inst_id, name, value from gv$parameter where name = 'undo_tablespace';

• Is it possible to change the State through several buttons?

  If I have already created, say, 100 identical buttons, and I want to change the State 'down' to a new color other than black. is it possible to do it quickly? I use 9 Captivate.

  Because you talked about "buttons" I assumed that you were pointing to the InBuilt States: Normal, rollover and down. The situation with styles is a little confusing IMO concerning States. You cannot set the States in Manager of Style of the object, as was the case of the Captivate 8 buttons. Since 9 Captivate, you will need to define States in the Panel object, for custom reports also state in regard to integrated States. Part of the InBuilt says are really integrated in the style: this is the case for all of the State for the Image buttons, for the background/outline for other types and form buttons. The labels on the buttons (text, system and form) are not part of the style. The exception are the image buttons because you have to put the text in the images. If you add objects in integrated States, they wil not be part of the style.  Even for States custom: they are not part of the style. I have problems with this configuration of confusing. It would be much easier, I think, if everything was recorded in an object style could be edited and changed in the Object styles Manager.

  The button menu "three lines", also called the hamburger or hot dog button, has opportunities to save changes to an existing style, to create a new style to apply a style to objects with a different style by default (as long as you override, leading + sign to appear).

  This no doubt confused answer: the workflow, I proposed with object styles, does that for characteristics that are saved in an object style (there no real explanation to help him as far as I KNOW). Now, I understand your last answer (sorry) that you are talking about a State that isn't integrated, but custom. In this case, you cannot change this State for all buttons at the same time. Only way is to duplicate the buttons. My apologies, I may have to write a blog about the object styles and its Director. I've heard several trainers proclaiming that they never use the OSM.

• Changing data in the undo tablespace or db Oracle buffer cache

  Hello
  
  I have serious doubt in the feature of oracle architecture, when a user issues an update statement, the data blocks are transported to the db buffer cache and where the data changes are made? Made a copy data block is stored in the cache db pads and the changes are made to the block in the buffer cache? or the copy of the data block is stored in the undo tablespace and changes are made to the blocks in the undo tablespace?
  
  In singles, the changes to the data blocks are make to the db or undo tablespace buffer cache?
  
  
  Thanks in advance
  
  Kind regards
  007

  Did you have a look to the Internet for the answer?

  In short, if a trial Oracle wants to update a record in the table, it does:

  -Read the record to be changed in the buffercache
  -Audits (the record already locked, is the update allowed)
  -Put the folder (called image before) in a rollback in the UNDO tablespace segment
  -Writing redo information about this change in the UNDO tablespace
  -Lock the record
  -Write the change in registration in the buffer cache
  -Put the change also in the redo buffer
  S ' sit and wait... (for a commit or a rollback)

  When are committed:
  -Release the lock
  -Empty folder of restoration since the UNDO tablespace
  -Write a record of this change forward in the UNDO tablespace

  When rollback:
  -Release the lock
  -Rinse the record changed the buffercache
  -Read the original value
  -Empty folder of restoration since the UNDO tablespace
  -Write a record of this change forward in the UNDO tablespace

  It of here, some more specific complexity when a checkpoint occurs between the change and the commit / rollback or redo buffer has been emptied for redo files

  Please any other s/n, correct me if I'm wrong...

  "I have a 2 RAC node and is it possible as inst1 can use the inst2 so undo tablespace in the case of undo tablespace to inst1 got filled,
  the research of new segments of cancellation, but not able to allocate new cancellations of the segments in the inst1 undo tablespace. »
  
  Thanks in advance...

  each instance will have its own undo tablespace and data from the before images of the database when generated will be stored with respect to special cases... The instance-specific tablespaces of cancellation cancellation segments are not shared it will settle in the shared common disks@SAN. so for instance or any other type of recovery recovery images before data will be drawn from required undo tablespace... Hope its clear...

  Concerning
