VC iView Communication error

[Former Member]

Hi,

We have transported VC models, iview, par from DEV to QA. When trying to preview the VC report we see the report but the whole page is grayed out and error popped with message

A communication error has occurred: [FaultEvent fault=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]. URL: /irj/servlet/prt/prtrw/prtroot/com.sap.visualcomposer.vcbroker"] messageId="AD3E8CB1-5FA5-2F11-2DC6-997B97D49BA2" type="fault" bubbles=false cancelable=true eventPhase=2]

After I click ok on the popup window, any event on the report again brings up this error popup window.

Any info on what is the fix?

NOTE: You may notice the above error message with strike please ignore it.

Thanks

Siva

HI,

In the portal system administration, Check the connectivity to the data-services you are using, and that the same system alias that you used in the model (on QA), is defined in the DEV machine.

it sounds like you have a general connectivity issue , rather than a VC issue.

Hi, thanks for the information. I have checked the system aliase and connectivity all looking good. The model is referring to same system alias in dev and QA. We still have the issue.

I don't see any logs in portal default trace NWA.

Thanks

Hi

Do you have neccesary authorization in the Backend system which you are using in VC Model also check whether you have proper rights for the execution of the iview.

I have required authorisation and right to run the VC reports. I can run the report directly in preview(Not the iview preview) mode in the VC model when I recompile.

We still have the same error.

Thanks

are you using the same user to view the report in preivew and iview mode.?

The error message is

A communication error has occurred: [FaultEvent fault=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]. URL: /irj/servlet/prt/prtrw/prtroot/com.sap.visualcomposer.vcbroker"] messageId="F3953E71-257A-0E9C-A134-BC0CB10536C6" type="fault" bubbles=false cancelable=true eventPhase=2]

I get this message when I click on iview preview the VC report launches in a new window as it try to render the page, the VC report access the backend system to retrieve dates to default on the report that is when the whole window goes in disable mode(grays out) a popup window with above message appears. If I click ok on the popup window then the window is back on normal but dates are missing in the field and when I try again by clicking on icon next to report field I get similiar error message with different text.

A communication error has occurred: [FaultEvent fault=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]. URL: /irj/servlet/prt/portal/prtroot/com.sap.visualcomposer.BIKit.default"] messageId="3F4EDE85-CCC5-1DD7-A8C7-BC1005EDBE59" type="fault" bubbles=false cancelable=true eventPhase=2]

The only difference between first error message and above error message is URL it's referring to.

The system objects that are used by this VC report is exactly same as in DEV system. It's all working fine in dev system.

Any thoughts.

NOTE: Just to let you all know again, there is no trace of any error message or info messages in defaulttrace.log or BI ABAP systems. The only error information we see is above message in a popup window.

Thanks

Siva

More info after troubleshooting further

We could successfully access the VC reports without SSL (HTTPS) all our development and unit testing is on HTTPS were all working correctly. We are now testing in QA under HTTPS that is when you have encountered this strange issue. Any thoughts?

One more finding adding to above post is, I can successfully access VC reports using https url in firefox browser. There is something in IE blocking the content under https.

When I did HTTPWatch trace in IE, the response is returning all correct content but it's erroring before it renders the page. Has anyone faced any IE browser 6 or 7 issue running VC reports in https?

Thanks

I am getting this same exact error when trying to run a dashboard in QA with IE 6. Please note if I run it for a smaller subset of data then the dashboard runs correctly and renders the image on the chart. Yet if I run it for a large set of data I get the same error:

communication error has occurred: [FaultEvent fault=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"].

Thanks everyone for your information. The issue is resolved.

There is a bug in IE 6 and 7 or even earlier versions of IE that loading XML files in Flash over an SSL Connection in Internet Explorer fails if the Pragma:no-cache or Cache-control:no-cache HTTP headers are set on the XML file. If you looked at your HTTP header stream and if you see above cache in the header the loading of flash will fail. If you try with firefox browser or IE 8 you won't get error message. This is only in IE 7, 6 and may be earlier versions bug.

The resolution is to check J2EE server of BI portal for following parameters

DisableDynamicCaching = false

NeverCompress setting for shockwave/flash

Hi Rochelle try above settings and more explanation of never compress for shockwave/flash means,

Disable the automatic compression of Flash objects, it seems that the J2EE is trying to compress them before sending them to the user, which is actually resulting in LARGER chunks being sent, and the application is actually working harder than it needs to

Change would be to add the following J2EE config to exclude mimes of type u201Capplication/x-shockwave-flashu201D being compressed by the BI Portal J2EE engines

VA ? GLOBAL --> Server --> Services --> HTTP:

NeverCompressed=xxxxxxxxxxx, application/x-shockwave-flash,[unknown]

i.e

NeverCompressed=.zip,.cs,.rar,.arj,.z,.gz,.tar,.lzh,.cab,.hqx,.ace,.jar,.ear,.war,.pdf,.gzip,.uue,.bz2,.iso,.sda,*.sar,image,application/x-compressed,application/zip,application/x-gzip,application/pdf,content/unknown,application/x-shockwave-flash,[unknown]

This will mean that flash objects are sent as is with no J2EE chunking or compression

The above settings has resolved the issue.

Thanks

Siva
