WebView - Clean install Triage Map error message

[Rodrigo Brandariz]

Hi everyone,

 

Here we have an stand-alone APM 9.0.5, with 3 agents 9.0.5 from 3 diferent WAS servers are connected to it. Today we upgraded to APM 9.7.1, according to the compatibility document the postgresql database was uninstall and then the new version was installed, then we upgraded APM directly. Everything works fine until we opened WebView. At this point nothing was restored in the database nor the Smartstore, not even modules, its a clean install of APM 9.7.1 with 3 agents 9.0.5 sending metrics.

 

The error occours only in the "Triage Map" tab, each time any element from the triage map tree is clicked an animation with the text "Loading" is shown in the upper bar with the time controllers, when the animation of loading finishes, a big pop up error message appears in front of the interface. Like this:

 

The logs of the WVService.log show this messages in INFO and DEBUG mode, there is no difference:

I noticed a behaviour of the AppMapTreeModel class too, each time it runs ok the duration is no more than milliseconds and when it fails it lasts several seconds:

I Hope someone could help me with this.

 

Thanks in advance.

Hi Rodrigo,

 

we have seen similar errors with IE11. Are you using IE11?

IE11 is not supported until APM 9.8. We have some genuine issues supporting IE11. I'm advising to run IE in compatibility mode or use alternative browser where possible.

 

Internet Explorer can be changed into a compatibility mode setting so that it can work with different web sites.

There is a little detail about how it works for Internet Explorer 11 below:

 

http://msdn.microsoft.com/en-us/library/dn321449.aspx

 

The compatibility settings can normally be changed on a per-user basis. To do that, a user can press the F12 key to start the developer tools menu.

They would need to choose the Emulation option, which has an icon of a monitor and a smartphone.

In the mode section, they should alter both Document Mode and User Agent String.

We would recommend that the customer emulates Internet Explorer 9 or 10.

The only workarounds beyond this are to use Chrome or Firefox, which as you have indicated might not be suitable for this customer environment.

Ciao,

Guenter

Thanks Guenter!

 

I was using IE11, I tested it in IE8 and the message dissapeared.

 

Best Regards.
