Sql Forms 2.3 help needed urgent

I have a situation here.How to navigate to the next blk, And If we make any changes in the .inp file will it help?
My client here uses Forms 2.3 for there Oracle Apps 10.7c

Use the block level trigger FND_NXTBLK, or if not in an AOL environment use NXT_BLK (if I recall correctly). This is how you navigate from block to block. The command would be
#EXEMACRO exetrg FND_NXTBLK;
or you could use go_blk
#EXEMACRO GO_BLK block_name;
The .inp file is your form. Don't edit it unless you know what you are doing. Use the SQL*Forms tool and you'll be safer.
Hope this helps. Not much detail in your posting. - Tristan

Some J2ME midlets doubts!! help needed urgently!!!

Hi,
I am currently working in a company where it does wireless technology like WAP and I am assigned a task of creating a screensaver midlet. I have some doubts on the midlets.
1) How do i use a midlet suites? From what I heard from my colleagues & friends, a servlet is needed for midlets to interact with one another. is it true?
2) How do I get the startin midlet to take note the phone is idling so that the screen saver midlet can be called?
Help needed urgently... if there is any source codes for me to refer to would be better... Thanks...
Leonard

indicates that MIDlet suites are isolated (on purpose) from each other, so you can't write over another one's address space.
Also, I believe (at least on cell phones) that you have to specifically enter the Java Apps mode; unless you do the app won't execute. If you are in Java apps mode and a call comes in, the cell's OS puts the Java app currently executing on "Pause" mode and switches back to phone mode.
Not sure if you will be able to have a Java app do that automatically.
BTW why do you need a screensaver on an LCD display? Is it really intended to show an advertisement?
Download and real all the docs you can from Sun, once you get over the generic Java deficiencies MIDlet's aren't that hard.

Help needed urgently on a problem..plzzz

hi..this is a linear congruential generator. I have to implement it and i need the execution time for the program.
for your understanding i'm providing an example below.
Xn=(( a* xn-1 )+b) mod m
If X0=7 ; a = 7 ; b =7 ; m=10
Then
X0 = 7
X1 =((7 * 7) + 7))mod 10 = 6
X2 = ((6*7)+7))mod 10 = 9
X3 = ((9*7)+7) mod 10 = 0
X4 = ((0*7)+7) mod 10 = 7
Now since the cycle is being repeated i.e 7 appears again�so the period is 4 coz there are 4 diff nos. i.e 7,6,9,0�..
help required urgently....your help will be appreciated...thankyou..

Hi,
I wrote the code so that it catches any cycle (not only the "big" one).
Otherwise it will enter infinite loop...
The time complexity is O(N*logN): it can do at most N iterations (here N is your 'm'), and in each iteration there can be O(log N) comparisons (since I maintain TreeSet).
Interesting issue: is it possible to supply such (x0, a, b, m) tuple such that all possible values from 0 to m-1 will be output? I think no :)
Here is the program:
package recurr;
import java.util.TreeSet;
import java.util.Comparator;
public class Recurrences {
     private static long x0, a, b, m;
     private static TreeSet theSet;
     public static void main(String[] args)
          long l0, l1, l2, l3;
          try {
               x0 = Long.parseLong(args[0]);
               a = Long.parseLong(args[1]);
               b = Long.parseLong(args[2]);
               m = Long.parseLong(args[3]);
          } catch(NumberFormatException nfe) {
               nfe.printStackTrace();
          System.out.println("X[0]: " + x0 + "\n");
          long curr = x0;
          boolean cut = false;
          int i;
          // initialize the set
          theSet = new TreeSet(new LongComparator());
          // we can get at most m distinct values (from 0 to m-1) through recurrences
          for(i=1; i <= m; ++i) {
               // iterate until we find duplicate
               theSet.add(new Long(curr));
               curr = recurrence(curr);
               if(theSet.contains(new Long(curr))) {
                    cut = true;
                    break;
               System.out.println("X[" + i + "]: " + curr + "\n");
          if(cut) {
               System.out.println("Cycle found: the next will come " + curr + "\n");
          } else {
               System.out.println("No cycle found!");
          System.out.println("----------------------------------");
          System.out.println("Totally " + (i-1) + " iterations");
     private static long recurrence(long previous)
          return (a*previous + b)%m;
     static class LongComparator implements Comparator
          public int compare(Object o1, Object o2)
               if(((Long)o1).longValue() < ((Long)o2).longValue()) {
                    return -1;
               } else if(((Long)o1).longValue() > ((Long)o2).longValue()) {
                    return 1;
               } else return 0;

Help needed Urgently- Rebate based on collected amount

Dear all,
I come across scenario while discussiion with client that they require rebate with collection. Details of the requirement are given below:
1. SAP rebates run on billed values & set the accrual in rebate agreement on the rate what we have specified in the rebate agreement. Requirement is that, If i have billed on 1000$ & my accrual value is 100$ with the rate of 10%. If i collected 800$ instead of 1000$, then i need to pay the accrual on the basis of 800$ not on the basis of 1000$. It means i have to adjust accrual amount on the basis of 800$. Conclusion is that i have to pay not 100$ accrual instead less then 100$ on the basis of 800$ which i collected.
2. In month 1 have billed on 5000$, my accrual amount is 500$ with rate of 10%. In the 2nd month i have to bill 1000$ and i have given an discount of 500$, it means my billed value is 500$ and my accrual amount is 50$@10%. In month 3 again i billed 500$ and my accrual amount is 50$@10%.
Requirement is that, when i am going to pay the accrual to client, i should pay correct accrual for which he is entitled for. Means i should pay 100$ accrual not 600$ because i have already given an discount of 500$. Discount which i have given already of 500$ should need to be offest with the first month accrual of 500$. So remaning accrual is 100$.
Great if somebody can help me out for the solutioning of the above requirements.

Thanks Ivano,
Somebody has started the conversation.
Let me put my questions again.
This requirement is nothing to do with Payment procedure in the agreement type.
1. In any month if i billed 1000$, so my account receivable would be 1000$. My rebate for that month is 100$ at the rate of 10%. During customer receipt if i collected against my invoice 900$ instead of 1000$, my accrual needs to be corrected 90$ instead of 100$.
I know this can not be fullfilled by standard SAP, by any thoughts on this welcomed.
2. I know Rebate can be settled partially or full settlement by payment method( by cheque, bank transfer, or by credit memo) we have configure in rebate agreement type. But here requirement is totally different.
Here, i need to pay the Rebate as a Discount instead of by cheque or by credit memo. While doing the partial or full settlement system will take into account collected accrual up to that day & apply as a discount to the final bill.
Scenario is like that sometimes customer asked to give us the discount on bill for whatever they accrued so far.
This is again cannot solved by standard SAP, but any thought by any body welcome. We have already thought that we need to enhance the solution.

Unable to allocate 27160 bytes.........Help needed urgently

hi
in my production database in getting this error..
ORA-04031: unable to allocate 27160 bytes of shared memory ("shared
pool","unknown object","sga heap(1,0)","session param values")
help needed urgently

If you have a program that does not use bind variables you can get this error.
In such cases you do not want to increase the size of the shared pool, but reduce it, and flush regularly. This is a bug in the application and should be fixed to use bind variables.
Another possible workaround is setting cursor_sharing = force, but this can cause other problems, so should only be used as a last resort. If the apps connections can be distinguished by user account or machine, then a log on trigger could be set cursor_sharing just for that application, to limit the damage until the vendor can fix it.

Sql loader help needed urgent

Hi,
I normally get a csv having data as
column1 ;columnb;columnc;
13 ; 12 ; 13 ;
11 ;13 ;33;
as the table where it needs to go is say table
xys( a number, b number , c number).
so the control file is fairly simple ...
But from now I need to restrict data entry if the change in format happens in the csv
say if it is like
column2;column1;column3,
12,13;12;
11;13;14;
or say the csv like
column1;column2;column3;column4;
11;13;14;15;
111;134;14;12;
in both cases sql loader should not run and throw the error saying the reason in the log.
how do i manage it in the control file `???
any ideas???
regards

Hello,
do you only need to check the first line of the file if it contains a line like
column1;column2;column3 ?
If yes, maybe a small script like this could be a starting point:
You have to replace "column1;column2;column3" with the header information that's valid and instead of file1 in the CURRENTSTRING=... Line write the name of your input file.
I hope this helps. (But maybe some of the experts here knows a way to do the verification checks with SQLLDR, so maybe its worth to wait a little bit :)
#!/bin/ksh
VALIDSTRING="column1;column2;column3"
CURRENTSTRING=`head -n 1 file1`
if [[ $VALIDSTRING == $CURRENTSTRING ]]
then
echo "They match."
else
echo "They dont match."

Oracle forms installation - some help need

I am trying to install Oracle forms - but get the follwing message:
Checking swap space: 576 MB available, 1535 MB required. Failed <<<<
Some requirement checks failed. You must fulfill these requirements before
continuing with the installation,at which time they will be rechecked.
Continue? (y/n) [n]
actually - I have no choice to choose y and try what's going on - so - is this means that I shoul add some 1.5 GB of RAM to my computer? (I have already 700MB, only 300 of them are used)? I am using WinXP, free HD is above 3.5 GB, 2.4GHz processor.
Can I try to find some workaround - e.g. simply try to copy jar's from 'stage' (direcotry in installation disk) in Oracle application server's lib directory (where it is in Oracle_Home directory?)?
Any experience with installing Oracle forms?
This was trying to run setup.exe, but when I am trying to run wsf.exe - I get:
SEVERE: Unable to locate the MDAC Update Status registry key value, probably because the installation was aborted.
MDAC possibly stands for Microsoft Data Access Components? If so - where is problem - I can run a lot of DB servers, including Oracle server itself normally?
BTW - is there any free service available for Oracle Forms skills development (e.g. as for Oracle SQL the Intel test drive is available?)

OK - now I increased the max limit of my page file and now I achieved this:

All installer requirements met.
Preparing to launch Oracle Universal Installer from C:\DOCUME~1\ADMINI~1\LOCALS

however - after this I receive the standard messgae:
'setup.exe has encountered a problem and need to close. we are sorry for the inconvenience..... Please tell Microsoft about thsi problem'
actually - I have little ideas what to do further - maybe I should look for other Oracle Installer version? I am using:
Oracle Universal Installer version: 10.1.0.2.0
and I am trying to install
Oracle Deveoper Suite: 10.1.2.0.2 (so - a bit higher)
I can run OUI without any problems, my Default JRE is 1.5_1 - so - all seems to be OK?
Please - if any idea - help me :))
Thanks in advance!

Web forms issue clashed - help needed!

hello experts,
i need an urgent as my website is now live, its beyond post-deadline. So I know a kind helpful solution to my problem. Ok here's the thing. I am unable to upload two webform in a single page. If i do add several web form into one page, the email notification won’t work. in other words, i will not receive any enquiries from customers. why is it not possible? i need to add different web form to different pricing option. please check out what i mean at my photography webpage at http://www.purpleperfect.com/wedding-offer-pricing.html
please help me resolve this issue, thank you in advance.

i guess that makes sense.... at least i need to add a second form at the bottom of the page, right on "click here".
btw, i have tested the forms, and it works fine. but if i add two different forms from bc into a single page, none of the forms will work within that page. i had this issue previously with my client website, but i never needed two webforms in a single page until today. do help me out.

Help needed urgently to get the values from the jsp page.

hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:

this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.

A puzzling situation...help needed urgently!

This is somewhat related to the topic I posted here (the app is the same) : http://forum.java.sun.com/thread.jspa?threadID=5253292
So I managed to set things straight and pass the value of the floor selected from the drop down list to a page called FloorPlanRender.jsp (the parameter name is "floorselected", and I store this parameter into an integer variable of the same name as shown in the code for the whole page below). A controller class receives the request, initializes the DB connection and redirects to the appropriate JSP page (not shown in the codes below, but it works fine) -
[BTW, I have posted the entire code for the page and classes involved...that was just to make the code more informative. The problem seems to be in a very small part of the code alone].

                    Now, using this value for floor selected, I have to get the rows and columns configured for this floor from a database. This involves performing a select max statement so that I can get the maximum row and column number respectively. So I call upon the relevant methods in the DataManager class by creating an object, which in turn gets forwarded to a class known as FloorPlanRenderPeer.java [The code for both are shown below]:

    catch (SQLException e) {
      System.out.println("Could not connect to DB: " + e.getMessage());
    return conn;

          try

     FloorPlanRenderElement oneelement = new FloorPlanRenderElement();
    Connection connection = dataManager.getConnection();
    if (connection != null) {

                          "from seatplanner.floorgridpart A, seatplanner.floorelement B where (A.floor_ID = " + floorselected +
                          "and A.element_ID = B.ID) order by A.grid_x_pos, A.grid_y_pos asc";
        try {
          ResultSet rs = s.executeQuery(sql);
          try {
            while (rs.next()) {
              oneelement.floorgridpart.setGridXPos(rs.getInt(1));
                 oneelement.floorgridpart.setGridYPos(rs.getInt(2));
                 oneelement.floorgridpart.setElementID(rs.getString(3));
                 oneelement.floorelement.setID(rs.getString(3));
                 oneelement.floorelement.setElementType(rs.getString(4));
                 oneelement.floorelement.setOccupied(rs.getString(5));
                 floorplanrenderelements.add(oneelement);
          finally { rs.close(); }
        finally {s.close(); }
      catch (SQLException e) {
        System.out.println("Could not get floor numbers: " + e.getMessage());
      finally {
        dataManager.putConnection(connection);
    return floorplanrenderelements;
}When I run the application and choose my floor, the result throws me a "No floor plan exists...." [the else...part in the jsp page].
I have come to know that it is because for some odd reason, the rowcount and columncount variables are not being set properly. I have tested the queries used in the FloorPlanRender peer class in the mySQL query browser and they work (both the row and column count for floor 3 for example, should return 20). But they don't. When I printed out the rowcount and columncount variables, they were set to a 0. I thought the floorselected parameter wasn't retrieved from the previous page properly, but to my surprise it was successfully set to 3, indicating the desired floor number.
I can't begin to see where the error is. There is nothing wrong with the DB connection or the query, but the correct value is not being set to the variables in the jsp page.
Can someone please have a look at the code and guide me as to what possibly is going wrong? I have spent a lot of time and effort and still haven't spotted the mistake, if any. Your help is much appreciated.

Again wrong usage of Iterator :)

</html>For god sake please bother to understand how any implementation of java.util.Iterator works
for more info go through javadocs
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Iterator.html
and i believe you have completey ignored my other suggestion of using enhanced loop in J2SE 5.0+ if iterator is confusing.
Anyways,hope the above might help you in fixing of what you are trying to..
