• A few quick questions in the OPS?

  Hi all

  I have a few questions for which I need clarification for the interview questions.

  1. If I made extension of VO and made customizing too on some pages. Even if we get an error. How to find out that we got the error and how to fix that?

  2. If we add 2 new columns to the page through the extension of the VO, then everything by customizing the page to create two new points to the table columns, what instance name of view we need to specify for items/columns newly created in Customizing, expanded Standard VO or OV name? and why?

  3. how to implement de FACTO forces in the OPS?

  4. at what level do you jpximport?

  5. can we make our pages on standard pages? If there is a way then please explain how?

  6 EO is necessary for all the pages in the OFA Standard?

  7. give me an example of the difficult task that you encountered during development in the OPS? Please specify at least one task.

  8. how to set the property(Rendered/Disable) of any article on click of a button without using a PPR?

  Please provide answers to these questions...

  Your help will be really grateful to understand more the OAF and interviews of crack.

  Thank you.

  9. can I make LOV messageTextinput in the standard page of the OPS? If yes how?

  You must hide the messageTextInput (make = false) and add a LOV using customization.

  10 can be done messageTextinput to LOV in the OFA standard page through customization?

  Same as above

  11. how to set the property(Rendered/Disable) of any item on click of a button, without use of PPR and set any value in processFormRequest?

  Could not set the property to processFormRequest. As I mentioned before, you have 2 options.

  1 true/false value declaratively or in PR

  2 attach an attribute of the VO property Render/people with reduced mobility.

  If this isn't the case, PPR, another page submit event must occur for this is reflected.

• HP Laserjet Pro M201dw: "then I explained the problem to management and they said not to buy all the HP printers more."

  Our two new printers Laserjet Pro M201dw are not recognized on the office network.   I have spent hours trying to understand this and posted questions on the forum Support HP, but without response. They became more disadvantages than thay are worth.  And that's enough.  Then I explained the problem to management and they said 'don't buy it not all HP printers more.'

  Thanks for the suggestions.

  I tried to BootP and disable ipv6 on a printer and at first, it worked (finally).  But then, after having unplugged and restarted, he returned to the ip address of connection no.

  So finally, I noticed and changed the setting of the link of "Automatic" to '100TX' speed full - and that seems to have solved the problem of intermittency.  I've converted and turn it back on, unplugged, etc., and it maintains the connection and ip address.

  Do not want to play with something that works, I can't say with certainty if the speed of one link would have solved the problem (probably not), but it seems that while your excellent suggestions finally established a network connection, the setting of explicit link speed was necessary to maintain the connection.

  Thanks for your help in this matter!

• How to explain the error in the executable file?

  As everyone knows, there are 3 parts to the cluster of error: status and source code. The State's flag, the code is the error code and the source is where Labview think that the error occurred. Normally, when I'm in the environment labview course I can just right mouse click the error and click "explain the error" and a description and detailed error possible cause rises.

  However, when I create an executable I don't know how to explain the error to the user, such as labview.

  When an error occurs that I wish I had a popup that says code error, source and EXPLANATION. The code and the only source is so enigmatic sound quite panic inducing the user, whether or not the error is unrecoverable/crash-inducing. Also this would save me having to search the online error code.

  How to make the explanation of the error code? There is a vi that I can enter an error code and get the explanation string?

  There is probably something simple I forget but I couldn't find the answer in my research. Thanks in advance for your help.

• Explain the explain plan

  decide to move to optimization soon. Book says join faster that the subquery in this example because the analyses involved. The "cost" to the subquery appears lower than the cost for the join. So it is confusing to me - aka How should I be interpreting this.

  Plan of subquery:

  

  join plan

  

  as you can see that the plan for the subquery has less than a cost. Could someone explain these outputs as to which application is more effective. I need to start somewhere.

  Thank you!

  The BEST way to get help when you ask questions is:

  1 ask questions on SPECIFIC things

  2. tell us EXACTLY what term, value, etc. ask abaout

  Book says join faster that the subquery in this example because the analyses involved. The "cost" to the subquery appears lower than the cost for the join. So it is confusing to me - aka How should I be interpreting this.

  OK - what BOOK are you talking about? There is not much interest to mention a book if you're not going to tell us which book it and provide a link to it and even a page number. This gives us the SCOPE of your question.

  This "cost for the subquery" are you talking about? Be specifc. It is in one of the plans that you posted? What plan? Whose cost is it? For example, you could say:

  I have a question for the foreground below. Why is the cost to the xx line lower than the cost of the second plan on line AA?

  This question refers CLEARLY to the info we're talking. The way in which you stating the question, we try to guess what plan and the lines you want to say.

  subquery plan:
  
  
  join plan
  
  
  as you can see the subquery plan has less of a cost. Could someone explain from these outputs as to which query is more efficient. I need to start from somewhere.
  

  Are you talking about line #1 in each of these plans?

  Please edit your post and tell us EXACTLY what you ask in the topic and refer to values and SPECIFIC lines. Also post a link to the book and a reference to a page number you got the information from.

  The optimizer generally chooses the REAL implementation with the lowest cost plan. It is not clear whether the plans that you have posted are ACTUAL spending plans that Oracle really determined and used or just explain plans.for what Oracle thought it might use.

  If the statistics are not up-to-date these plans do not yet reflect the reality of the data.

  And if the amount of data is a small number of blocks or other of these plans can run better than the other in reality.

• Question about cardinality (lines) to explain the plan

  I have two tables (names have been changed to protect the innocent):

  
  

  TABLE 1:

  
  

  The Null columns?    Type

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

  Table1_Primary_Key NOT NULL NUMBER

  more than 10 columns
  

  
  

  TABLE2:

  Table2_Primary_Key NOT NULL NUMBER

  more than 8 columns
  

  
  

  Lines of table1 has 1097172

  
  

  Rows of table2 has 160960
  

  
  

  I am analysis request and get explain below:

  
  

  SELECT t1. Table1_Primary_Key

  --

  FROM TABLE1 t1,

  From TABLE2 T2

  --

  WHERE t1. Table1_Primary_Key = t1. Table1_Primary_Key

  AND t2. Table2_Primary_Key = 3432798

  /

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

  
  

  As you can see it table2 is exactly 1 row and join table1 on a correspondence of single line.

  
  

  My question is this:

  
  

  Why the plan of the explain command seems (at least for me) to indicate that it looked like all the rows in TABLE1?

  
  

  Thank you

  the optimizer's decisions are based on the object (and maybe system) statistics: so it's a good idea to provide as much information as possible in these statistics. Basically, there is nothing wrong with statistics automatic collection job - so I would count on that if I don't have very good reason to use anything else. Of course, there are some situations in which it's a good idea to add a few adjustions for automatic collection: sometimes, there is too much created histograms, sometimes there is too little (basically you have histograms when the distribution of the data is not yet). And if there are columns with correlated values who serve together in boundary conditions then create extensive statistics may be a good idea. To make these adjustions, you can use the routines of pref dbms_stats. And sometimes, it may even be a good idea is not to collect statistics for an object and use the sample dynamic (dynamic statistics) for more detailed information on the cardinality of distribution and join.

  In the book of my opinion Jonathan Lewis cost base Oracle Fundamentals still contains the best explanation of the use of optimizer statistics - and Christian Antognini Oracle performance troubleshooting also provides a lot of valuable information about statistics and their gathering. Of course the documentation also explains the basics in detail: Managing optimizer statistics - 11 g Release 2 (11.2). And if you want to get a shorter summary, then you can always take a look at the Web of Tim Hall site: https://oracle-base.com/articles/misc/cost-based-optimizer-and-database-statistics.

• Unable to get the parameter by using a controller in the OPS

  Hello!

  I am new to using the OPS and will very much appreciate your help!

  FYI:

  Basically, I need to add 2 descriptive flexfields in a page (by creating a VO) and I need to update the table with the data stored on these de facto forces (I did all the logic already).

  I created a (CO) controller that calls a method that is declared in an application module (AM) that runs a stored procedure (CO and the AM were created by me and that they extend a standard CO and I am).

  Problem:

  However, updated just before... I'm having a problem because I can't get a parameter using paramContext.getParameter("reqHeaderId"). who will help me to identify which line I need to update.

  Because the statement is not capture the value, it returns a null value, and I got the following error when I try to convert it to a number in: oracle.apps.fnd.framework.OAException: java.lang.NumberFormatException: null

  It is really important to mention that, before we get to the page where I clicked the Send button that makes the logic mentioned... There are 2 pages before that where I'm trying to capture the setting and the required parameter is defined on the 1st page. I have been checking each standard CO 3 pages and they use the statement pageContext.putParameter ("reqHeaderId"); to switch between the 3 pages (as far as I know, if not please correct me). On the 3rd and last standard CO that it uses pageContext.getParameter ("reqHeaderId"); to get the value and make another logic.

  So why Im not getting the value if I do the same thing (pageContext.getParameter ("reqHeaderId") ;) on my xxController (which extends the standard co)?

  
  

  Here is the code of the controller:

  public class xxController extends standardController {}

  ' Public Sub processRequest (pageContext OAPageContext, OAWebBean webBean)

  {

  super.processRequest (pageContext, webBean);

  }

  ' Public Sub processFormRequest (pageContext OAPageContext, OAWebBean webBean)

  {

  super.processFormRequest (pageContext, webBean);

  String str;

  Str = pageContext.getParameter("_FORM_SUBMIT_BUTTON");

  If ((str! = null) & & (str.equals ("SubmitButton")))

  {

  String ReqHeaderId = pageContext.getParameter ("reqHeaderId");

  String ReqLineId = pageContext.getParameter ("reqLindId");

  [Serializable] Parameters = CLIENT1

  {

  ReqHeaderId

  ReqLineId

  pageContext.getParameter ("xxavtBienServicio") //dff

  pageContext.getParameter ("xxavtAttribute3") //dff

  };

  String var = (String) am.invokeMethod ("updateAttributes", parameters CLIENT1);    updateAttributes is the method that converts it to ReqHeaderId number and runs my stored procedure

  }

  }

  }

  Thank you in advance for your help!

  Hello

  I found the reason why I have problems to get the needed values.

  The reason was that the given property has been set to false in order to use pageContext.getParameter must be set to true. So, I went ahead and created as a "value of the form" this way I could put the melted property and keep the hide at the same time field.

  Thanks for your help!

• How to get the full name of the user of the OPS?

  Hi Experts,

  I know we can get the login controller pageContext.getUserName () user name. Is there a simple way/API to get the full name of the user (name, first name) of the OPS?

  Thank you.

  Hello

  USER name and information of the PERSON are two different concepts. You can get the id of user with pageContext.getUserId () connection. In order to get the first name, last name, you must select it from table PER_ALL_PEOPLE_F.

  You can use the sql select and set pUserId of pageContext.getUserId ();

  SELECT FIRST_NAME, LAST_NAME TO PAP PER_ALL_PEOPLE_F, FND_USER FU

  WHEN TRUNC (SYSDATE) BETWEEN PAP. EFFECTIVE_START_DATE AND PAP. EFFECTIVE_END_DATE

  AND FU. EMPLOYEE_ID = PAP. PERSON_ID

  AND FU. User_id =: pUserId

• Is he closer to display the data in graphic format in the OPS?

  Hello Experts,

  I'm working on a feasibility OFA study and I have a question: is there in the OPS, any approach to represent data in graphic format, such as the schema of the Terminal?

  As far as I know, ADF supports this kind of representation and it can be incorporated into the OAF page as region. But it seems to separate server for the ADF, which is not supported in my project (assuming we have only EBS server). And the situation is similar for embedded Analytics OBIEE approach.

  Would like to share your experience or the reference of this kind of solution? Appreciate your help in advance!

  Thank you and best regards,

  Clark

• Report of the OPS / s

  We currently just bought a new storage and I'm looking for the best way to get reports of the IOPS / s of our virtual machines. Specifically, I want to get the OPS are / s for the last quarter on schedule from 07:00 - 18:00. We're currently on vSphere 4.1. A good majority are desktop view, that's why I want to look specifically at opening hours. Any ideas? Thank you!

  Here's a quick and powershell (really) dirty way providing the average and maximum read and write of IOPS / s over a period of days:

  $daysback = - 30
  $vms = get - VM
  "write-host (" {0, -40} ' t 1.8 t {2,8}} 't {3.8}' t {4,8} "-f"VM"," IOPS / s W avg ', ' Avg R IOPS / s "," W IOPS / s max "," IOPS R / s max ")"
  ; $vms | kind | % {
  $wval = (((get-Stat_$_-stat_"datastore.numberWriteAveraged.average"-Start_(Get-Date).adddays ($daysback) - Finish (Get-Date)) |-expandproperty value Select): measure - average - max);
  $rval = (((get-Stat_$_-stat_"datastore.numberReadAveraged.average"-Start_(Get-Date).adddays ($daysback) - Finish (Get-Date)) |-expandproperty value Select): measure - average - max);
  write-host ("{0, -40} ' t {1, 8:N2} t {2, 8:N2} ' t {3, 8:N2} t {4, 8:N2} ' f $_.) Name, $wval.average, $rval.average, $wval.maximum, $rval.maximum)
  }

  Output is as:

  VM W IOPS avg IOPS R / W IOPS avg s / s max IOPS R / s max
  VM1                                                1,96            0,67            7,00           31,00
  VM2                                                0,46            0,53            7,00           17,00
  VM3                                                7,57            7,66           52,00           73,00
  VM4                                                3,47            0,00             4,00            0,00
  [...]

  Remember that historical performance data are rolled up in the DB vCenter. So if you query data from the last 30 days as in this example, the values are made upwards of 2 average hours wrapped in the comic book. Especially the peak values can seem a little low then. Go to-1 (dailly, 1 minute averages) or - 7 (weekly, 30-minute averages) in this case and run it periodically.

  Also, here is a version that will assess only the values with a timestamp between 07:00 - 18:30:

  $daysback = - 30
  $vms = get - VM
  "write-host (" {0, -40} ' t 1.8 t {2,8}} 't {3.8}' t {4,8} "-f"VM"," IOPS / s W avg ', ' Avg R IOPS / s "," W IOPS / s max "," IOPS R / s max ")"
  ; $vms | kind | % {
  $wval = (((get-Stat_$_-stat_"datastore.numberWriteAveraged.average"-Start_(Get-Date).adddays ($daysback) - Finish (Get-Date)) |?)) {$_. "Timestamp.ToString () - match" (0 [7-9]: 1 [0-8]) :'} | Select - expandproperty value) | measure - average - max);
  $rval = (((get-Stat_$_-stat_"datastore.numberReadAveraged.average"-Start_(Get-Date).adddays ($daysback) - Finish (Get-Date)) |?)) {$_. "Timestamp.ToString () - match" (0 [7-9]: 1 [0-8]) :'} | Select - expandproperty value) | measure - average - max);
  write-host ("{0, -40} ' t {1, 8:N2} t {2, 8:N2} ' t {3, 8:N2} t {4, 8:N2} ' f $_.) Name, $wval.average, $rval.average, $wval.maximum, $rval.maximum)
  }
