OVwAlertMsg() error:OVw APP NOT FOUND

ITEM: RS4000016652



**************> QUESTION level 1 --> level 2 SPECIALIST <**************         
We made some application using NV/6000 V2.1 APIs.                               
Our application calls OVwAlertMsg() to send message to nvevents.                
                                                                                
Our application abend calling OVwAlertMsg(), and error code was 1, it           
means "OVw_APP_NOT_FOUND". Programmers Reference says "There is no              
ovw application running that is dispatching alert messages"                     
                                                                                
But the time the trouble was occured, trapd and nvevents were running.          
We want to know what's the "ovw application running that is dis-                
patching alert messages", and why these error was occured.                      
                                                                                
Thanks and regards.

I checked with Rob Macgregor and he confirms that, in our opinion,              
you did not have an EUI (ovw) running.

Sorry for my insufficient explanation, but I have an ovw running.               
                                                                                
I got this error when ovw starting and system (ovw) is very busy.               
I want to know what are the conditions to success OVwAlertMsg ( in              
other                                                                           
words, to not return error from OVwAlertMsg ).                                  
                                                                                
If ths OVwAlertMsg returns error, our application is terminated.                
I have registered the application to *.reg and enabled to restart from          
menu of NV. But the application terminated again when calling                   
OVwAlertMsg. In this case, ovw is not busy.                                    
                                                                                
If you like, let me know about mechanism of message dispatching.

I will check with development.  I have seen situations where it ended           
up necessary to take the EUI down/up to recover from error situations           
caused by (for example) a time-out to a paricular call.                         
                                                                                
I will let you know if there are some hints.                                    
                                                                                
It could be you are headed down a product-defect (PMR) path.  We see.

 Dave,                                                                          
                                                                                
 I looked at the code and it seems as though you will get this error            
 message if there is no application currently registered to receive             
 ovw alerts (via the OVwAddAlertCallback() function).  I would                 
 have the customer check to see if they have any such applications              
 (noting that the Programmer's Reference says that a program that               
 registers for the events can not also generate them).                          
                                                                                
                                                                                
 From Dave:                                                                     
                                                                                
 I assumed, based upon their question, that they had applications               
 running which would satisfy their generated event; or, if they had             
 an EUI running that ovevent would satisfy it -- but, perhaps they get          
 the error when things are not started yet.  We see.
