Two "Wait for Notification" with single Notifyer?

I feel like I should know this answer, but my code was buggy when I did this.
Can you have multiple "Wait for Notification" VIs attached to the same Notifyer?
The help seems to suggest that Notifiers are only for two independent loops:
Notifiers are a tool for communicating between two independent parts of a block diagram or between two VIs running on the same machine.

Can you have multiple "Wait for Notification" VIs attached to the same Notifier?
Yes
See the Notifier Demultiplexer example.

BDC for notification with sales order

Hi,
I have to code a BDC program for IW51 : Service Notification with sales order.
The problem is that in simulation mode (SHDB) the button "Sales order" is not working !!!
although it works well in transaction mode!
please help!
A+
Ihsen

hi all,
so anyone came across any BAPI or FM that creates Orders from Notification.
My requirement is similar to "Order Explode" functionality in WPS1 transaction (MEB). For two notificaitons, if the task list having the same operation and same type, then a single order gets created.
I want to know whether any FM/ BAPI is available that creates Order in reference to Notification. I just want to simulate Order creation.
Waiting for reply.

How to create a new business partner for notification with function module?

Hello,
I got a problem when I want to create a new Notification with its businiss partner (BAPI_ALM_NOTIF_CREATE). I can't find the proper way to create the new business partner. Anyone offer some help?
Thanks a lot!
Morgan

when I look at the function you can transfer the partner in NOTIFPARTNR table.
You must already have defined the appropiate partnerroll in customizing for you're businesspartner
or do you have another problem with this function ?

ORA-00060: deadlock detected while waiting for resource with Tbs Read-only

Hi all,
We're using Oracle 10.2.0.1 and 9.2.0.4.
I'm testing the performing of a procedure that inserts, like this:
CREATE OR REPLACE PROCEDURE P$TAD_TEST
IS
TYPE T_T1_C1 IS TABLE OF T1.C1%TYPE INDEX BY PLS_INTEGER;
TYPE T_T1_DT IS TABLE OF T1.DT%TYPE INDEX BY PLS_INTEGER;
P_C1 T_T1_C1;
P_DT T_T1_DT;
P_RESULT NUMBER;
BEGIN
FOR j IN 1..4032 LOOP
P_C1(j) := j;
P_DT(j) := SYSDATE + (j/24/60);
END LOOP;
FORALL i IN P_C1.FIRST..P_C1.LAST SAVE EXCEPTIONS
INSERT INTO T1 VALUES (P_C1(i), P_DT(i));
EXCEPTION
WHEN OTHERS THEN
P_RESULT := SQLCODE;
END;
The table T1 is partitioned across 10 tablespaces. The test consist to take
these tablespace read-only and perform the procedure, and analyze the results,
like erros.
but when I perform the procedure, The alert.log indicates the error
ORA-00060: deadlock detected while waiting for resource.
Why this occurs only the tablespaces are read-only?
thank you!!!!

The status/location indicator bar (says waiting for, communicating with, etc) across the bottom is gone, how can I get it back?

I can't find out where the line that tells what Firefox is currently doing has gone to. It usually says things like, "waiting for response from", "loading", "done". I rely on that status bar a lot and I have no idea what it is called, or where it went. Can anyone help?

Where are the answers???? Why hide them? This is very annoying!!!

Two deductions for invoice with same reason code posted as one line item

Hi
We have a scenario wherein we are taking two or more deductions on the same invoice and are using the same reason code which have a setting of charge off.
SAP system displays the FI posting with same reason codes with charge off setting as one line item.
However we want the FI Posting to display separate line items per deduction and not combine amounts of deductions based on same reason code with charge off setting.
Any comments are appreciated.
Edited by: Kirti Bhardwaj on Jul 24, 2011 9:46 AM

Hi,
you can use different reason codes in distribute differences screen once you have fist selected one reason code for one invoice.

How to display DB specific data in WEBI for users with Single Universe

hi,
I have a WEBI report which is based on Single Universe, which can support both Oracle and SQL Server databases.
There are 2 users for this report.
1) Oracle_User
2) SQLServer_User
When 'Oracle_User' opens report in InfoView, he should see the data from Oracle DB
When 'SQLServer_User' opens the same report in InfoView, he should see the data from SQL Server DB
Please let me know how to achieve this functionality.
Can we dynamically change the Universe connection based on the User who logged into InfoView..?
Thanks,
Vamsee

hi Anil,
Thank you for the response.
I have tried creating 2 connections and restricted each connection for each group, but in Infoview, only one group user is able to refresh the report, whose connection is exported along with the Universe. when the other group user tries to refresh the report, an error is displayed 'You donot have access the data from this Universe'.
So the reason is : 'As Universe can be exported to Repository with only one connection' that connection specific group user is able to access data from Universe Whereas other groupuser cannot( as other connection can't be exported along with the same universe).
As Universe can be exported to Repository with only one connection, how should these connections set for the corresponding groups?
Could you please provide me the detailed steps w.r.t connections restrictions...?
Thanks,
Vamsee

Long time wait for authentication with Windows 2003 AD

Hello,
We have a problem with authentication with 2003 AD. If it was no requests from VDI to Windows 2003 AD during some time (10-15 minutes), first request take a lot of time - 3-5 minutes and user need to wait after entering his username/password. Searching users in VDI GUI also take a lot of time in this situation.
How to resolve this? Size of directory is very small.
And with 2008 AD and Open LDAP there is no such problem.

Same thing for 2003, it is called IAS (Internet Authentication Service).
http://www.microsoft.com/technet/network/ias/default.mspx
Basically you will set up IAS with a RADIUS Client which would be your wireless access point(s). Then you will set up a remote access policy which will define how connections are authorized or rejected (windows groups, protocols etc.). Don't forget to register IAS with active directory.

Wait on notification, occurence. is it sleep?

Hai
Am using PXI with RTOS, it has 2 processes . i need to wake up a task on an event, execute it and then sleep again. I wanted to know if i can use Occurence or Notifers to achive this. Since these uses wait on notification and wait on occurence functions i wanted to know if the thread is in sleep mode when in this function, since this is a high priority task if it is waiting on notifier am afraid it will dominate CPU and does not give time for normal priority tasks to execute.
Thnx for any reply

The thread running your high priority VI in which you wait for notifier (or occurrence) will be "blocked" until you send notification (or set occurrence). While the thread is blocked, other threads will run, including lower priority threads. One way to verify this is with the execution trace tool.
If you don't have the trace tool, there's another way to test this. In a normal priority VI, obtain a notifier and call a while loop*. In parallel, call a time-critical subVI that waits for notification (see attachment). After the loop finishes, send notification. This VI will finish, which means the time-critical subVI had to relinquish the CPU in order for the normal priority parent to send notification. Otherwise, we'd be waiting forever for a notifi
cation in the time-critical subVI.
*Put sleep in the while loop to ensure that LabVIEW reaches the time-critical subVI before the while loop runs to completion.

Wait for variable to become true...

Hi,
I am writing a program that involves networking. I want the program to do nothing until a certain condition is true. This loop will take about 90% of my processing power(as reported in task manager, windows xp) with the way it is written now. This isn't good, because when this program is complete there will be dozens of threads, and having dozens of threads socking up processor power like this just doesn't work. So if anyone can suggest a way to pause the loop until in[0].ready(), or in[1].ready(), or ... in[n].ready() is equal to true.
Thanks

               try

                         if(in.ready())

You want to use the wait - notify features of Java.
Something like this
final Object lockObject = new Object();
Thread t = new Thread(new Runnable() {
public void run () {
while(true ) {
synchronized (lockObject) {
lockObject.wait(); //waiting for notify of action to perform.
//do stuff
t.start();
Thread t2 = new Thread( new Runnable() {
public void run() {
synchronized ( lockObject ) {
Thread.currentThread().sleep(1000);//to show it's working wait for a second before notifying the other thread.
lockObject.notify();
t2.start();This code creates 2 threads which share the lockObject. The first thread waits until the second thread notifys the lockObject. Basically, instead of setting a boolean variable to 'true' you would use the wait - notify aspect of the object.

Change Notification with C#

I am trying to get a test application to work using Oracle Change Notification with C#, but I am not receiving the callback notification in my application. Oracle DB version is 11.2.0.1.0. Oracle.DataAccess v.2.112.30. I can confirm the query gets registered in Oracle by viewing SYS.USER_CHANGE_NOTIFICATION_REGS and SYS.USER_CQ_NOTIFICATION_QUERIES. However, nothing ever appears in SYS.DBA_CHANGE_NOTIFICATION_REGS.
The registration persists until I commit a transaction on the table. The registration disappears after a few seconds after the commit and my application does not received the notification.
I have made sure my computer is listening on the correct port and have even tried turning off any firewall that could be blocking the port.
I do have GRANT CHANGE NOTIFICATION to MYSCHEMA, GRANT EXECUTE ON DBMS_CHANGE_NOTIFICATION TO MYSCHEMA, and the JOB_QUEUE_PROCESSES is set to 1.
Questions:
1) Should the registration be visible in SYS.DBA_CHANGE_NOTIFICATION_REGS and, if so, what could be causing it not to be when it is visible in SYS.USER_CHANGE_NOTIFICATION_REGS and SYS.USER_CQ_NOTIFICATION_QUERIES?
2) What could be causing the registration to disappear after a commit?
3) What could be causing the failure of the notification to my application?
Here is the C# code I am using and it is basically the same as from the Oracle website:
using System;
using System.Threading;
using System.Data;
using Oracle.DataAccess.Client;
namespace NotifyTest
public class Program
public static bool IsNotified = false;
public static void Main(string[] args)
string constr = "User Id=mySchema;Password=myPassword;Data Source=myOracleInstance";
OracleDependency dep = null;
try
using (var con = new OracleConnection(constr))
Console.WriteLine("Registering query...");
var cmd = new OracleCommand("select * from mySchema.NOTIFY_TEST", con);
con.Open();
OracleDependency.Port = 1005;
dep = new OracleDependency(cmd);
dep.OnChange += OnMyNotificaton;
int queryRegistered = cmd.ExecuteNonQuery();
// If oracle returns -1, then the query is successfully registered
if (queryRegistered == -1)
Console.WriteLine("Query Registered...");
Console.WriteLine("Listening for Callback...");
else
Console.WriteLine("There was an error...");
catch (Exception e)
Console.WriteLine(e.Message);
// Loop while waiting for notification
while (IsNotified == false)
Thread.Sleep(100);
public static void OnMyNotificaton(object sender, OracleNotificationEventArgs arg)
Console.WriteLine("Table change notification event is raised");
Console.WriteLine(arg.Source.ToString());
Console.WriteLine(arg.Info.ToString());
Console.WriteLine(arg.Source.ToString());
Console.WriteLine(arg.Type.ToString());
IsNotified = true;
}

Just wanted to provide an update as to how I resolved this issue. I changed my Oracle.DataAccess.dll from v.2.112.3.0 to v.2.112.1.2 and it works fine.

Which Wait-on-Notification's (of all types) are currently Waiting?

I may have a wait-on-nofication deadlock. Before I use the Navy method (beat to fit, paint to match) by changing a bunch of WoN's Wait-on-Notification-with-History, it would be great simply to be able to see which WoN's are currently waiting. In this way I could maybe see which WoN's were participating in the deadlock and hence rethink my dataflow pattern. I haven't found a tool highlight WoN's, list WoN's, etc. But it sure would be handy.
Any info or ideas?
Solved!
Go to Solution.

The desktop execution trace toolkit might show you who's waiting (or at least in which VI). I haven't used it so I'm not sure.
Another option for handling this in code is to use a timeout and not do anything if the timed out output is true, but this is most likely going to be a hack instead of a real solution in your case.

PO with single & multiple account assignment

Hi expert,
I got one PO with single & multiple account assignment. How should I book invoice. I try using MIRA for items with multiple acct and MIRO for items with single acct. I works but can I do it in one shot instead of splitting. If so, how?
One more thing: if I got invoice saved in MIRA but without any items. It can't be changed. It say it is schedule by background. How could I change it?
Thx

Hi
You can use MIRO to check book the invoice for both single account assignment and mulitple acc assignment.
You have to select the lay out Account assignment with cost center.
For Multiple account assignment you can see the Button in the line item, click it to maintain the multiple account assignment.
Hope it helps.
Thanks /Karthik
