• ADF is intended for the data base designed with vertical diagram?

  Hello
  
  I want to know if ADF 11 g is intended for the data base designed with vertical scheme where even the names of columns will be stored in a generic table?
  
  Thanks in advance.
  
  Published by: user8925296 on April 12, 2010 10:06

  The short answer is no...

  What do you call a 'vertical plan', it's what others have called for a schema of entity-attribute-value or universal data model. I advise you to do some research open minded on these types of patterns if you develop an application before continuing. Great sound in practice, they have very inherent ease of use and scalability problems.

• The Oracle trace: number of physical reads of the signifier of disk buffer

  Hi all

  
  Since yesterday, I was under the impression that, in a trace file Oracle, the "number of physical buffer of disk reads" should be reflected in the wait events section.

  Yesterday we add this trace file (Oracle 11 g 2):

  call the query of disc elapsed to cpu count current lines

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

  Parse        1      0.00       0.00          0          0          0           0

  Get 9 1.96 7.81 65957 174756 0 873

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

  total 11 2.01 7.84 65957 174843 0 873

  Elapsed time are waiting on the following events:

  Event waited on times max wait for the Total WHEREAS

  SQL * Net more data to the customer 5 0.00 0.00

  SQL * Net client message 9 0.01 0.00

  ********************************************************************************

  We can see that the 65957 physical disk reads resulted only 5074 direct path read. Normally, the number of physical reads from disk is more directly reflected in the wait events section.

  Is this normal? Why is that? Maybe because these discs are on a San have a cache?

  Best regards.

• The TYPE of CFINPUT DATEFIELD = won't accept the date from the data base

  I had a weird problem which I think may be just a way to explain to the server how to interpret value. I use ColdFusion 8 with SQL SERVER 2005 Express. In my table, the field is a DATETIME field and the date with time (eg. 2007-07-23 00:00:00).
  
  In my form, when I added using the DATEFIELD as the CFINPUT type, it records the date correctly. But when I use the EDIT.cfm form and try to put the value of the database in the CFINPUT DATEFIELD, the server generates an error. Here is the error:
  
  2007-07-23 00:00:00 / 0 is an invalid date or time string.
  
  Of course, I tried many things but I tried to force the date with DATEFORMAT format (qGetNewsInfos.dtIssued, "mm/dd/yyyy '") and many other format but without success.
  
  Is he knows how to use a date in the case of a < CFINPUT TYPE = DATEFIELD >?

  Try dateformat yyyy-mm-dd.

• Not be saved in the data base of page elements

  Good afternoon
  
  I hope that it is a return of holiday brain cramp but I don't see the problem... I'm working on a help desk application and when a closed ticket is displayed, a button to reopen ticket. When the button is clicked: P5_STATUS_CODE should be replaced by reopened; P5_CLOSED_BY_KEY & P5_CLOSED_DATE must be null. the record must be recorded and the page redirected on itself.
  
  I've created a submit after process (sequence 10) that updates the fields with a condition that it triggers when the button reopen ticket (APPLY_CHANGES).
  
  Start
  : P5_STATUS_CODE: = 'reopened ';
  : P5_CLOSED_BY_KEY: = null;
  : P5_CLOSED_DATE: = null;
  
  wwv_flow. Debug ("P5_STATUS_CODE value = ' |: p5_status_code");
  end;
  
  Because the button to reopen ticket has a REQUEST of APPLY_CHANGES type, it triggers the process of update DML (sequence 30). Then the branches page on itself.
  
  Looking at the record in the database, I see that the date of modification (engine database trigger) is correct but the status code and closed fields were not updated.
  
  When I run the form with debugging, the process works and by the debug statement, the value of P5_STATUS_CODE is replaced by Reopened. Then the process of the DML is run. And finally the branch runs.

  If the box is not displayed then the items are not part of the subject page and will not be part of the automatic DML. Try creating another process sequenced after the automatic DML. This process must be a simple update statement updating these columns in your table.

  1. What is the fastest way and to do this, if there is one?
  2. all the Documentation on the migration steps?
  3. do we have to use any tools 3rd part for this?
  4 can we reach the migration of data with sql loader, if so is it the way suggested to do this, and is there a documentation on that?
  
  I tried developer sql to do the migration, but it doesn't go well and finally found that is not the way to migrate a database with peoplesoft, here is the link environment to explain more about what I've done with sql developer.

  (1) build an Oracle system demo patched for the same level of output than the current system of production.
  (2) launch the application designer and compare the production system for the demonstration for you system can capture changes.
  (3) load a custom table with the tables listed in the MVPRDEXP. EXP in the production system. Run a script to create a script to export for all PSRECDEFN where the RECTYPE is 0. This identifies all application data tables. You may want to dms export large tables in parallel.
  (4) DMS import the exported data in the Oracle instance.
  (5) re - apply changes.

• Limitations of the data base

  Windows Server 2008 - Oracle 11g 11.2.0
  
  I was checking Oracle Enterprise Manager.
  There is a warning as limits of data saying that open cursors are 2185.
  I checked some settings:
  open_cursors: 12000
  session_cached_cursors: 50
  
  To me, it seems that the limit is far from overflowing...
  So, I try to understand why I got this warning.
  
  Could you please help me?
  
  Ed

  You should be able to click on the link to the warning and access to an open cursors screen which will show you the warning and critical levels, as well as your recent history. On my machine, it seems that the default value is 1200, which is far from my normal use - it's the kind of humor that warning message was sent at time of my use to a minimum. Why it checks how to is one of those mysteries of the universe. You could try setting levels in the settings screen to manage, but on older versions on my platform, which has been a challenge.

• More powerful hardware worst performance on the data base why?

  Dear all
  
  Help, please. I have recently improved our 10.1.0.3 to 10.2.0.4 database on a new server (Windows 2008 Server quard Core 64 bit with 6 GB of RAM). The third party software that will work perfectly, now malfunctioning.
  
  
  
  I have compiled a list of summary points.
  
  In summary:
  
  
  Point 1. A PC (core 2 processor double 32 bit, with 2 GB of RAM on windows XP) runs faster (a windows 2008 server running in the Quard Intel core with 6 GB RAM 64 bit) the two machines are defined to use 70% of the computer's memory (IE total SGA + PGA)
  
  Point 2. When the third-party software works the number of session (v$ session) varies. In some part of the application, it takes 60 + sessions to run a single report for a generation single end-user. (PC use much less session about 12 sessions)
  
  Point 3. The report that generates the session 60 + (I mentioned in point 2) also takes very long time 20-30 minutes (the report still run on the PC run a lot fasters 3-5 minutes)
  
  Point 4. Third party software is written in VB and Chrystal reports.
  
  
  Questions: -.
  
  1. How is the performance are so poor, even though we have more powerful hardware on the server than the PC?
  2. when applications run, and I have observed creating mulitple sessions and destroy is this mean he runs some sort of parallel query on the database?
  3. is there anything I can do to improve the speed of the server?
  
  concerning

  P.S. I statpack data but when I copy and paste the windws text and preview, the look of terrible format so I leave.

  Not unusual.

  It could be that the configuration used for the new server is not appropriate to use efficiently the resources of that server.

  This may, for example, designate a bottleneck caused by the use of more powerful equipment. For example, the I/O layer can manage server maybe pushing 80 Mb/s and 100 Mb/s. Most powerful processors are used, and these now perform i/o more calls per second and shoot n/b I/O required at 160 MB/s. This seriously overloading the IO layer and cause a blow all around performance drastically.

  Better support has the knack to better show how the software is designed and used. It allows the code to misconfigured software, designed and written to error even more and cause more problems, per second.

  3. is there anything I can do to improve the speed of the server?

  Who says that there is nothing wrong with the speed of the server?

  Observing that s/w is slower (VB and Crystal Reports as mentioned), it's just that - the observation of a symptom. This does not mean that the server is slow or there is a problem with the speed of the server. The server can run fast. Could just be that it runs a misconfiguration or poorly written software, very fast.

  A poor or inexperienced driver will seem a small car and slowish, fine. Put that person in a sports car and inability of the person to drive will quickly become very noticeable. This isn't the fault of the car.

  Similarly, I see not the question by looking at the server as being the problem - as if some buttons need to be pressed and switches put in order for automagically solve the performance problem.

  You must watch the symptom and identify what is the real problem. Only once you have identified the real problem, can it be addressed and solved.

• Between the records in the data base - year wise

  Hi Experts,

  I have a database and I want to separate year files wise in a form of database.

  A database for 2013

  A database for 2014 and so on...

  There is currently no procedure for separation of records.

  Reports are increasing day after day.

  I intend to do this by querying each table and storing a different database.

  What a way to make?

  Cecile

  It takes less storage to add storage to a database it does to create a separate database for each year of data you want to store, so your argument to save cost and space is invalid.  It is not feasible; a partitioned table would be a good approach, as has already suggested it.

• Customization of the user for users of the data base and without security ADF

  JDeveloper version - 11.1.1.7.0

  I want to implement personalization by the user on the database of users and without ADF security. I followed the link in storing the repository in a file system but its same showing below the user interface for all users.

  http://Sameh-Nassar.blogspot.IE/2012/03/apply-MDS-to-Oracle-ADF-application.html

  Please guide me on how to do this for users of the database. Please share any other useful links, as appropriate.

  Customization of the user (SDM) does not care the security of applications. You can also apply to the MDS in your ADF application if you use the ADF security or custom security. The main idea is the class of customization (like MyUserCC) has the method call getValue this method should return the user name. When the user login stores the user id in the session and the method getValue returns the user session ID as:

    public String[] getValue(RestrictedSession restrictedSession, MetadataObject metadataObject)
    {
      try
      {
        String user = (String)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("userId"); // userId is the session variable that store the login user id
        if(user == null)
        {
          return new String[]{""};
        }
  
        return new String[]{user};
      }
      catch (Exception e)
      {
        e.printStackTrace();
      }
      return new String[]{""};
    }
