Hi,

I am facing an issue with displaying the PDF generated with WebFOCUS in IE.

Here is my problem. I deployed the ASP.NET (C#) application in place an year ago. Everything was working fine till a week back, but then I get a call from the owner of the site telling me that the PDF files are not getting displayed for few users occassionally.
I am not able to reproduce this in any of the developer's[team] machine. But, I could see this in a different machine with the same configuration, very rarely. I checked this and sure enough, when you click on the link that displays the PDF file, the browser goes blank. I discovered that if you hit the refresh button on the browser the PDF file will load into the browser just as it always did.

Please help me to resolve this issue.

Thanks in advance.

This sounds familiar, could it be an IE issue ?

This issue occurs very rarely.
The developement machine and the testing machine(where the issue occurs) are of the same configuration.In fact i could reproduce it just once in one of the development machines.
When this issue occurs I am not able to view most of the reports in the application in different machines at that moment of time.
So i dont think this has anything to do with the IE.

That looks very much like either a WebFOCUS / HTTP / application server issue.
However if it recovers without any intervention I would be inclined to suspect a network issue of some sort.

If it was a network issue, this would have happened in all the machines at that time.
But the issue occurs in very few machines.
We have heard from the client about the agent crash almost the same time when this issue occurs. Does this have anything to do with WebFOCUS agent crash?

A very important piece of information and key to the resolution.

You need to look very carefully at the code and try to get a reproducible
scenario so that you can take some traces.

If the reports were running fine up until just over a week ago that implies that
there has either been a change on the server or a change on the clients.

A good starting point would be to find those changes.

Another possible cause could be corruption in you source data, trying to perform
some subroutines on invalid input can cause a crash.

This seems unlikely however as if that were the cause the crashes would be consistent.

Really for something like this you should raise a case with IBI support.

I agree with JG:

I may be the data as well. Are these failures coming about as the results of the same "Test Case"? I have also seen that, on occasion (especially on Windows / PDF), that Adobe PDF has issues. Check that out via Task Manager on the machine which is failing to display the PDF document.

I dont think its a data issue.Because its failing for the same test case occasionally.
