• What is the problem with the sequences on RAC environments?

  Version: 10 g, 11G
  
  I've never worked on CARS. But I keep seeing discussions about the problems with the sequences on CCR environments. What exactly is the
  basic question?

  Can be performance issues if you have a large number of sequences of nocache as it may cause heavy IO for the system tablespace.

  Given that each instance will have its own cache seqeuence that some sites are unhappy with significant gaps in the values, this can cause.

  There was also a blocking problem caused by heavy simultaneous new connection activity requiring the issuance value audsid for the session of v$. To solve this just to the top of the cache size to 1,000 or 10,000 by default if you are on a version where the value was not moved upward by Oracle already.

  As far as the first two numbers go that my view is if the sequence does not need to be cached you need not use a sequence to generate value. If you need a value without interval then you need to get your value from a table column value that is part of the transaction and do not use a sequence in a first time.

  Sequences are designed for speed and concurrentcy, and this competition is priced at gaps.

• Error-1074135024 with the sequence mode arbitrary two-channel on SMU-5451

  Hello

  I am trying to use both channels on my SMU-5451 and operate in arbitrary sequence mode.

  In the build step start, I get the error-1074135024:

  Possible reasons:
  Invalid value for the parameter or property.

  Attribute values are not similar in the channels or the specified features. Use a unique channel name or feature name to query the value.

  Unfortunately, I have no idea what parameter or property value causes the error.

  Initially, I tried this with my own VI, and I was able to run each channel individually, but could not get them both to operate simultaneously. As an attempt to troubleshooting Finally, I decided to change the example of arbitrary signals Fgen (Dual Channel) (which worked properly), to see if I could get it to work with arbitrary sequences. I still get the same error. I enclose modified VI, because it is quite a bit simpler than what I'm running.

  I'm under Labview 2012.0.1f3 (32-bit) on a Windows 7 Enterprise (64-bit) operating system.

  Thanks for any help you can offer on how to solve this problem!

  So with the help of your VI I have figured out how to make it work.

  First of all, your VI I noticed that I should wire the specific channel, I just want to niFgen Create VI waveform, but not in VI of arbitrary sequence niFgen set up. For this I devrais either do not fill in the entrance of the channel, either entry "0.1". This gets rid of the original error message that prompted this post.

  Your VI works, but it seems to be designed to write on only one channel at a time. However, I noticed that if I run it with all the waveforms channel 0, change the waveforms to be on channel 1 and click load & sequence, waveforms will be correctly output channels 0 and 1.

  Finally, I worked on that the trick is to create an arbitrary sequence, so use the arbitrary Create Sequence niFgen and niFgen configuration arbitrary sequence screw, single-channel waveforms. Then run the niFgen Clear VI arbitrary memory, then create another arbitrary sequence for the other channel. After that, run the generation VI niFgen undertake. And everything works fine! I don't know why it is important to have clear memory arbitrary VI in the Middle, but it seems to be essential for this to work properly.

  I downloaded my VI relatively simple test that works properly with this arrangement.

  Thank you very much for your help.

• How to copy clips with the sequence markers?

  Hello

  Anyone know if it is possible to copy clips from one scenario to another with markers (not the clip markers) above them? I have found no way to do it, but maybe someone has an idea, I thought.

  Thanks in advance!

  mchl

  It is not possible.

  The best you can do is nesting the sequence so that the sequence markers will appear as clip markers in the nest.  From there, you can duplicate these markers.

• problems with the sequence of images in v30

  First of all, I'm a bit of a novice user in the teaching of science. I use this software to deliver the anatomy & Physiology TP laboratory where I take a sequence of images from several angles of an anatomy model and use the image sequence feature in InDesign to link them together so that the student can drag the picture on the iPad to rotate the image and see the issue from several angles. This worked very well with v29 and students loved it. However, with the v30, with just a light tap of the image, it quickly reverses through many images, almost randomly, after the coup. This makes all our efforts on the worthless 3D appearance. I can't use one of these rotating images now until this problem is corrected, or tell me what goes wrong. Any ideas?  To learn more about how I have this set up? It works fine when I preview the file on my laptop. This is only on the viewer Adobe iPad application (which is used in the classroom). Thank you!

  For 6-8 images, I think I would use a MSO, instead.

• error with the sequence of keys in cmds.cfg

  Hello

  I was the redefinition of the keystrokes for frequently used commands. I read it in the Customizing_Frame_Products_menus.pdf file.

  They all work just after that I opened Frame 7.2 except one: Esc mpu (\!mpu)

  I set this sequence of keys to open the Master Page use. The first time I have try, Frame complains that "no anchored frame chosen." This happens after I press Esc mp.

  The solution is to select view-> menu-> edit, select the configui folder, select the cmds.cfg file and click on modify. The framework console lists a mess to redefine the messages command, but after mpu Esc works correctly.

  I tried the other cfg files but found no other instance of \!mp (the actual sequence of keys).

  Everyone knows about such behaviour?

  Yours,

  Michael F

  =======

  Michael,

  The key sequence is probably get redefined when loading.

  I hope that you have create your keystrokes redefined in a separate file and do not edit the file cmds.cfg of origin. FM treats the .cfg files in a specific order with cmds.cfg first, then wincmds & mathcmds .cfg files and and then user changes in the file defined in the maker.ini entry:

  ConfigCustomUIFile=fminit\configui\customui.cfg

  It would be better from a maintenance point of view to create your own custom and then cfg file point to it in the maker.ini. This means that you don't have to load it manually. Alternatively, you can create various cfg files mini loading only the changes that you want to do it manually.

  A great starting point for customizations of FM (in addition to using the Adobe guide) is more Shlomo Perets ToolBar to: http://www.microtype.com/resources.html

  If you want to see which loads the FM as key-sequences in your specific case of FM, then get a copy of ListShortCuts plugin ( http://leximation.com/tools/info/listshortcuts.php ) to Scott Prentice. This will create a table of all the active shortcuts.

• TRIGGER - how to auto fill a column with the sequence

  Hello
  
  I have a table that contains information about the customers... I have bound him to a form of the APEX so that when a user enter information through a form he generates a sequence/trigger number and saves it in the column (named tracking_NO)... I use this tracking_no as key for monitoring purposes.
  
  My problem is that when the admin will post information from MS access to Oracle, it generates automatically a number for my column 'tracking_No '... Please advice how to use the same trigger Auto Fill a column (tracking_no) when the value is zero.

• Creating a trigger to insert delete update with the sequence number

  Hey all,.
  I have two tables. tbl_main, tbl_temp. Whenever a record is inserted, deleted, updated in tbl_main, I need to insert the records in tbl_temp. All field/column names are exactly the same, except that in tbl_temp, I now have a single column by using a sequence number, a column to determine if the record has been updated, remove, modified(hence the codes) and the date when a record has been added to the table.
  So far, that's what I have:
  
  create or replace
  audit_trg relaxation
  after update or insert or delete ON tbl_main
  for each line
  Start
  If the update can
  insert into tbl_temp (seq_id, idx, ctl, action_taken, date_added)
  VALUES
  (temp_seq.nextval, idx, mke, ctl, sysdate, 'U');
  ELSif INSERTION then
  insert into tbl_temp (seq_id, idx, ctl, action_taken, date_added)
  VALUES (temp_seq.nextval, idx, mke, ctl, 'n', sysdate);
  ELSIF deletion then
  insert into tbl_temp (seq_id, idx, ctl, action_taken, date_added)
  VALUES (temp_seq.nextval, idx, mke, ctl, would be ', sysdate);
  END IF;
  END audit_trg;
  
  I tried several combinations, but I get many compilation errors. This code looks good or I am the way of track? Thanks in advance.

  Who looks fine for me. What are the mistakes are you?

  Assuming that MKE and CTL are columns in the base table, your INSERT statements will insert either the: new.mke and: new.ctl values or the: old.mke and: old.ctl values in the table. Presumably, you could insert the: new values for inserts and updates, and the: old values for deletions.

• Export issues of sequences with the correct settings for DVD

  Hi - I'm relatively new at first, but working on a project that is very important for me - for the life of me I can't understand correctly export settings.

  I have compiled from home movies of my family in a few sequences for the 60 years of my dad. I worked on these weeks now get cleaned and put all together. In total, it's about 24 hours of footage. These videos have all turned initially on a very old camera video in the 80 and 90 - the kind you actually stuck a VHS tape in. My ultimate goal is to put these or on a DVD (although I guess that's too many images for one), or a drive flash or something of all compiled in one video.

  So far, I got error messages on not enough disk space - so I tried breaking the sequences and exported individually as smaller files. But now, when I export those, all videos come out tiny - the video focuses on a much larger screen, do more fit to size. I studied everything about elongation and corresponding parameters and I tried everything. Of course I do not something good, I don't know what.

  I tried all different export settings, the settings of the sequence, and I thought I was following with the sequence settings, but I guess I'm not. Although I worked on it for weeks, I am out of time. His birthday was yesterday, and I wanted to give her the finished disc tomorrow. This does not seem possible as I am about to give up!

  Someone please help! I would be grateful if someone could guide me through what my sequence settings should be and what my export settings should be and how to get the video output to the correct size for the screen.

  I appreciate your help,

  Danielle

  Time of export will vary widely, depending on at least these factors

  1 - your computer... Processor and the amount of RAM, and is this external drive, USB2 and USB3?

  2. what you change, and effects that you have applied your 718 x 480 video size... is odd, the usual when scanning a VHS tape is 720 x 480, so your video requires 'some much' extra processing

• Help! Need to change the size of the video in the sequence of project...

  When you create a project last month I accidentally created as 1280 x 960 in the sequence settings, but to create as a 1920 x 1080 which is what all the video clips are of size. Now, I have this well-edited project, but must convert it to a 1920 x 1080 in the sequence settings so I can export as this size. When I go in the sequence settings now this option is grayed out and it won't let me. I read many forums and they say it's easier to create a new sequence with the right settings and import the old sequence but when I do that it's always like 1280 x 960. So my question is other than the re-release of this project together, how can - I take this ongoing project with the sequence like 1280 x 960 settings and change the size of the video up to 1920 x 1080 (which is what the video clips are initially and when I right click on the videos it says 1920 x 1080). Please help, I use CS5 PP! It's so frustrating!

  A big thanks to everyone! I followed all your advice and got to work, the only thing I had to do was to manually resize the titles but everything else was perfect, thank YOU!

• How to maintain the sequence DB value if we don't save the record?

  Hi friends,

  I created a Page creating and defining the primary key (Empno) with the sequence of the DB column. This method, I'll call you in PR

  Here is the code and it works fine.

  public void createRecord() {}
  OAViewObject vo = getXXEMPNEWEOVO1();
  If (! vo.isPreparedForExecution ())
  {
  vo.executeQuery ();
  }
  Number seqNo = getOADBTransaction () .getSequenceValue ("XX_EMP_S");
  Line = vo.createRow ();
  row.setAttribute ("Empno", seqNo);

  vo.insertRow (row);
  row.setNewRowState (Row.STATUS_INITIALIZED);
  }

  If I record the record, it is saving without any problem.

  But here is my requirement, if I do not save the file I'd be losing sequence. I don't want to lose this sequence.

  Ex: Current Seq: 10

  When I go to create the page: the seq is 11. If I save it, it will get stored in DB without any problem.

  Instead of save, I'll close the page and to reopen the page, this time, a new sequence will get generated, that is to say 12. But 11 has disappeared. I don't want to miss this 11.

  I wrote the same code in the method Create() of EO. He works also as same (above).

  I tried to write the code in the button Save, I am getting error below:

  Error -

  Empno in PraciceAM.XXEMPNEWEOVO1 attribute is required.

  CO code:

  OAViewObject empupdatevo = (OAViewObject) am.findViewObject ("XXEMPNEWEOVO1");

  TXN OADBTransaction = am.getOADBTransaction ();

  Number of seqNo = txn.getSequenceValue ("xx_emp_s");

  Line = empupdatevo.getCurrentRow ();

  row.setAttribute ("Empno", seqNo);

  Can you help me please on this.

  A quick response would be much appreciated.

  Note: This issue, I was also asked to interviews, I was empty.

  Thank you

  Srinivas,

  Once recovered DB sequence value cannot be restored.

  Few options for you:

  1. set a dummy value say-1 initially, then drift and set the value of the sequence on the click on save.

  2. set the validation server = false on the "Save" button. But it stops to throw another error in the page on the click of the button.

  3. you can substitute doDML() and try to set the sequence value in this, but it will take once again the dummy value-1 as the first option.

  Hope this helps and answers your question.

  See you soon
