Error Descriptions

[Former Member]

Is there documentation on what diffrent errors mean? We get a lot of stall transaction and HTTP 500 errors but we do not know what root problem this is indicating.

Hello,

   I have the same problem during Jmeter tests but i didn't know if end users  will see this error...

/BOE/portal/1312231434/InfoViewAppActions/ajaxUre/ajaxRequest        error http 500

  This error is shown when the number of http request is important.

  I'm still looking for solution.

ciao

Hi Ludo,

An AJAX request is made between the browser and application server server.  It allows data to be updated in the browser without actually refreshing the entire page.  Pretty much all of our web applications (including BI Launchpad) are using AJAX requests to provide it's dynamic functionality.  The important thing to understand here is what is the cause of the HTTP 500 error.  In otherwords, we need to see the full Java stack associated with the error.  You could check your Java Application Server system.err logs to find the full exception stack. 

Thanks

Toby

Did you ever get a resolution to this - we have the same problem

Hi Calvin,

What information are you looking for specifically? 

Thanks

Hi toby,

I am looking to try and diagnose the stalled transactions and HTTP 500 errors that I see constantly in the RSC live error viewer.

I can see this sort of thing

• Error at 15:01:46.864 (10 Apr 2014)
• Frontends|Apps|SAP BusinessObjects InfoView Actions|URLs|Default (0 ms)
• DataCreationType: 0
• Method: service
• Thread Group Name: main

• Trace ID: 1397138507133:198453
• Trace Type: ErrorSnapshot
• Servlets|com.businessobjects.jsf.explorer.servlet.UREServlet (0 ms)
• DataCreationType: 0
• Error Message: HTTP Error Code: 500
• Method: service

every couple of minutes - but I am not making any progress finding out whats causing them

(the apache server has things like

[02/Apr/2014:08:29:26 +0100] "POST /InfoViewAppActions/ajaxUre/ajaxRequest HTTP/1.1" 500 29”)

The stalled transactions looks very similar in the live error viewer.

• Error at 15:00:31.286 (10 Apr 2014)

Hey Calvin,

We really need to see the full java stack for the HTTP 500 error.  Attach your system.err and system.out logs generated by Tomcat that corresponds to the time that you see the Introscope error transactions.  It should contain the full details.

Do your end users report seeing the error in their browser?

Thanks

Toby

Our tomcats dont produce system.out and system.out as such, they seem to put the java stack in the stdout_20140526.log instead - but since they dont contain a timestamp for the errors, I havent been able to match the access log entry

[29/May/2014:10:00:45 +0100] HTTP/1.1 500 cookie:- request:-  POST /InfoViewAppActions/ajaxUre/ajaxRequest   POST /InfoViewAppActions/ajaxUre/ajaxRequest HTTP/1.1 0.012

and I dont see the expected stack trace in the log

The errors dont seem to get reported directly to the users either

Hi Jason,

Although this isnt specifically for Wily Introscope, it may help to decipher some errors you might encounter:

[XI31 SP3 Error Messages|http://help.sap.com/businessobject/product_guides/boexir31SP3/en/xi31_sp3_error_messages_en.pdf]

I'll see what else I can find for you.
