  Hello

  I'm looking for here is I'll have the release of the full scheme. Now, I want to import only a single table based on a specific condition rather than import the full dump.

  I get the error when you use parfile as you suggest.

  Not too, I've said to parfile "+ no need to back slashes +"...?

• [ADF, JDev12.1.3] Managed beans: when I have to worry about serialization (de)?

  Hallo,

  I would like to know what type of beans and in which case, I have to worry about serialization (de).

  When is it enough to simply add implements Serializable class definition? Which is the right class to import?

  And when I really need to implement (de) serialization by myself and how I can do? One (or more) example forward.

  For example, in a range session bean I use a recorder and some standard attributes...

  public class Login  {
    private final Logger logger = oaw.model.Config.getLogger(Login.class.getName());
    String A;
    Integer X;
    // ...
  }
  
  

  ... what should I do?

  In general, if a bean stores no data (de) serialization has no matter, right?

  Information you provide me... better is

  Thank you

  Federico

  I would like to know what type of beans and in which case, I have to worry about serialization (de).

  In all the grains that can survive a http request-response cycle.

  It is usually related to clustering, but it may be important if you use UserData structure in AM.

  When is - it enough to simply add implements Serializable class definition? Which is the right class to import?

  When you have java simple types or types that already implement the Serializable interface.

  See: Serializable (Java SE 7 platform)

  For example, in a range session bean I use a recorder and some standard attributes...

  1. public class {Login
  2. private final Logger logger = oaw.model.Config.getLogger (Login.class.getName ());
  3. String A;
  4. Integer X;
  5. // ...
  6. }

  ... what should I do?

  Just mark your connection with the Serializable attribute class.

  In general, if a bean stores no data (de) serialization has no matter, right?

  Right.

• Doubts about licenses

  Hi all
  
  I have a few doubts about the price of licenses.
  
  I understand, I can deploy an APEX Server 11g XE free of charge, but what happens, if I want to install, a version no XE?
  
  Imagine a billing application, for 10 users, and I will assume that a Standard is sufficient. With the help of [this price list | http://www.oracle.com/us/corporate/pricing/technology-price-list-070617.pdf], how much exactly will cost?
  
  I understand I can get a license by user or server, or I have to license user and server too?
  
  Kind regards.

  Hello
  metric license is named plu user or license CPU (see the table of the core).

  for a quote, you can take a look in the oracle store or ask your dealer for an exact price oracle.

• I have a doubt about the file .folio and publications

  Hello, I m new here.

  I want to start working with DPS, but I have a doubt about which version to buy.

  At the moment I have one customer just wants to publish a magazine, but my intention is to have more customers and publish more magazines.

  If I buy the unique edition of DPS, I read that I can publish a single file .folio. What it means? Each folio file represents a publication?

  Please, I need help to understand this before you purchase the software.

  Thank you very much

• Doubts about event handlers

  Hello
  
  I had some doubts about the event handlers in the IOM 11.1.1.5...
  
  (1) I want to use the same event handler for the message insert and update Post task... Can I use the same handler for this... If Yes, then how can I make...
  
  (2) can I create the single class of Plugin.xml and add all the jar files in IE single lib folder and zip them all together... If yes then what changes I need to do? Need only add that the plugin tags for different class in the plugin.xml file files? OR need to do something extra too...?
  
  (3) if I need to change something in any class handler... Is it need to unregister the plugin and register again...?
  If Yes... Is it need to delete the event handler using the weblogicDeleteMetadata command?
  
  (4) that we import the event handler of the path as event manager/db /... If we add all the evetn handler.xml files in this folder... As when importing weblogicImportMetadata called recursively all files in this folder... Now, if I need to change anything in one of the event handler class... so if import us from the same event manager/db folder... What to do... Create the copy of the eventhandlers? OR should I not add Eventhandler.xml files to class files, I made the changes...
  
  (5) given that I need to create emails on the creation of the user while recon and identification of email updated as a first name or surname updates... I had to use in the event handler.xml (entity-type = 'User' operation = "CRΘER") or something else...
  
  
  Help me clarify my doubts...

  Yes, on the update post you need to be check first if the first and last name change to update the mail electronic id, rather then calculation always email identification. So, you can check the path name are updated through the previous code.

• Doubt about appsutil.zip in R12

  Hi all
  I have doubts about the application of rapid Clone on 12.1.3.I the latest patches have applied the fix using adpatch. After that, it must synchronize directories appsutil
  in RDBMS oracle home. I created appsutil.zip in the application layer and copied in the RDBMS oracle home. If I move the old appsutil to appsutil.old and extract appsutil.zip, the new appsutil directory should not constituted by the context file (I think). So, I have to run the automatic configuration based on the old cotextfile. Below, I have summarized the steps that I follow. Please check and correct me if I'm wrong.
  
  Copy appsutil.zip to $INST_TOP/admin/out of RDBMS oracle home
  CP $CONTEXT_FILE /tmp/mytest_vis.xml
  MV appsutil appsutil.orig
  unzip appsutil.zip
  Run autoconfig based on/tmp/mytest_vis.xml.
  
  
  Thank you
  Jay

  Jay,

  Is there a reason why do not use the old file context? What is the difference between the context file that will be generated by adbldxml.pl and the old file context?

  If there are updates in the application, it will be updated in the new xml file generated by adbldxml.sh, but he's not in the old file.

  So it is always best to run adbldxml.sh and autoconfig.

• Doubts about RAC infrastructure with a disk array

  Hello everyone,
  
  I am writing because we have a doubt about the correct infrastructure to implement RAC.
  
  Please, let me first explain the current design we use for storage Oracle DB. Currently, we are conducting multiple instances in multiple servers, all connected to a SAN disk storage array. As we know that it is a single point of failure so we have redundant controlfiles, archiveds and Orde in the table and in the internal drive of each server, in which case table has completely failed us 'just' need to recover cold backup nightly, applied hoops and Oder and everything is ok. This is possible because we have autonomous bodies and we can assume that this downtime of 1 hour.
  
  Now, we want to use these servers and implementing this table to a RAC solution and we know that this table is our only point of failure and wonder if it is possible to have a RAC multi-user solution (not AS a node) with controlfiles/archs/oder redundant internal drives. Is it possible to have each written full node RAC controlfiles/archs/oder in drives internal and applies these files systematically when the ASM filesystem used for CARS is restorations (i.e. with a softlink in an internal drive and using a single node)? Maybe the recommended solution is to have a second table to avoid this single point of failure?
  
  Thank you very much!

  Fix. It is the right solution.

  In this case, you can also decide to simply use the distribution on both tables and mirror of the array1 array2 on table data using the ASM redundancy options.

  Keep in mind that the redundancy is also necessary for connectivity. If you need at least 2 switches to connect on two tables and two HBA ports on each server, 2 fibers running, one to each switch. You will need driver multichannel s/w on the server to deal with the multiple I/O paths for storing same lun.

  Similarly, you will need to repeat this step for your Interconnect. 2 private switches, 2 cards on each server which are pasted. Connect then these 2 network cards on the 2 switches, one NETWORK card per switch.

  Also, don't forget to spare parts. Spare switches (one for the storage and interconnection). Spare cables - fiber and everything that is used for the interconnection.

  Bottom line - not a cheap to have a redundancy solution. What we can do is to combine the layer of Protocol/connection of storage with the interconnection layer and run both on the same architecture. Oracle database machine and Exadata storage to servers. You can run your storage Protocol (e.g. PRSS) and your Protocol (TCP or RDS) interconnection on the same 40 GB Infiniband infrastructure.

  As well as 2 switches Infiniband are needed for redundancy, plus 1 spare. With each server running a dual port HCA and one cable for each of these 2 switches.

• Doubts about the speed

  Hello gentlemen;

  I have a few questions, I would like to ask more experienced people here. I have a program running on a computer that has a processor i7 processor. In this computer that I have programmed in LabVIEW, meanwhile in another lab, we have another PC, a little older, a dual core 2.3 Ghz, in this pc, we perform a testing platform for a couple of modems, let us not get into the details.

  My problem is that I discovered recently that my program, I programmed in the computer, i7, much slower work in the other machine, the dual core, so the timings are all wrong and the program does not run correctly. For example, there is a table with 166 values, which, in the i7 machine are filled quickly, leaving almost without delay, however, the double machine heart, it takes a few milliseconds to fill about 20 values in the table, and because of the timing, it can fill more values and so the waveform that I use is all wrong. This, of course, live of the whole program and I can't use it as a test I need to integrate.

  I have create a .exe program in labview and try it in the different PC that's how I got to this question.

  Now, I want to know if there is actually a big problem due to the characteristics of the computer, the program is slow in one machine. I know that, to ensure the eficiently program, I need to use States, sub - vi, idea of producer-consumer machines and other things. However, I discovered this is not a problem of the speed generated by the program, because, if that were the case, the table would eventually fill it completely, however in slow computer, it is not filled more with 20 values.

  Else, helps to hide unnecessary variables in the front panel?, because the time beeing I have keep track of lots of variables in the program, so when I create the .exe I still see them runing to keep this follow-up. In the final version, that I won't need them so I'll delete some and hide front panel some. It helps that require less condition?

  I would like to read your comments on this topic, if you have any ideas in machines to States, sub - vi, etc., if there is a way to force the computer to use more resources in the Labview program, etc.
  I'm not add any VI because, in the current state, I know you will say, state machines, sub.vi and so on, and I think that the main problem is between the difference in computers, and I'm still working in the things of the State/sub-VI/etc

  Thank you once again, we just let this hollow.

  Kind regards

  IRAN.

  Get started with, using suitable as a machine for States stream you can ensure that your large table would be always filled completely before moving on, regardless of how long it takes. Believe it or not add that a delay to your curls will do more all the program run faster and smoother, because while loops are eager and can consume 100% of CPU time just a loop waiting for a button press, at the same time all other processes are fighting for time CPU.

• Some doubts about the navigation in unifying

  Hi all

  I had a few questions about unifying navigation.

  Is it possible to move the admin mode user mode access level?

  I mean, if a particular feature as Manager of the shell I can only access from admin mode is it possible to provide access even in user mode?

  If so, how?

  My 2nd question of doubt is, currently, we can access company BPs level "Journal of society" or "Resource Manager" under shell 'Company Workspace'.

  Is it possible to move the "journal of the society" or "Resource Manager" in the folder? If yes how?

  I tried in "navigation user mode" to move the company BPs level at shell of the House, but I can't do it.

  To answer your questions:

  (1) User-Mode browser can have the user feature included. You cannot change the view mode Admin or move functions admin for user mode.

  (2) you cannot move these on the Home tab.

• Doubt about joins

  Suppose that there is a small sql statement
  
  Select a.*
  FROM table1, table2 b
  where a.column1 = 'SAMPLE_VALUE'
  and a.column1 = b.column2
  
  now my doubt is
  "is the left side is equal to the right side or on the right side is equal to the left" which is correct.

  No, it will not decrease the performance of the queries. Optimizer decides the execution of this plan should be. If you have a condition:

  a.Column1 = b.Column2

  opimizer will decide which is more efficient: get a.column1 and then search for b.column2 or get b.column2 and search for a.column1.

• Doubt about the UTF-8 encoding!

  Hello

  I m, developing an application supporting the multilingual. When I send the request to the server for the french text I have a string containing french as characters (ex: error in react reciprocally with the Blackberry Natal service.). Therefore to help these characters I've coded the string that is received from the server to support utf - 8 encoding using the code below

  private String readResponseAsString(InputStream strInput)
              throws IOException {
          byte[] data = new byte[256];
          int length = 0;
          StringBuffer strRawData = new StringBuffer();
          while (-1 != (length = strInput.read(data))) {
              strRawData.append(new String(data, 0, length,
                      "UTF-8"));// Character encoding
          }
          String strResponse = strRawData.toString();
          return strResponse;
      }
  

  which is called when the reply is received from the http connection in the input as stream below:

  // Response in the form a Input Stream
                  oInputStream = oHttpConnection.openInputStream();
                  // Response in the form of a String
                  strResponse = readResponseAsString(oInputStream);
  

  Now the prob is the french characters sometimes like(ex: é) are coneverted ot '? "despite the utf-8 encoding, the response string... And increasingly, it only happens for a very little characters and only for a very few times...

  I'm doing something wrong?

  I suggest to read the data in the first, using http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/io/IOUtilities.html#streamToBy...
  You can then create a utf-8 string from the byte array.

• Doubts about ButtonPress

  When I press the button on blackberry phone, I should get the menu options, I want to know how to achieve this, IT has the default close the menu and I want to know how to add the menu and I want to know what the character of the key.

  It's the image

  Concerning

  Rakesh Shankar.P

  You can override makeMenu for the screen, or makeContextMenu for a particular domain. You can read about the menus in the development guide.

  When the user presses the menu button, a Keypad.KEY_MENU to the key event is sent to any KeyListener saved with the current screen. But in General, you're better off replacing the functions in menu appropriate instead of listening to the key.
