SAP Web dispatcher issue

[former_member192181]

Hi All,

We are not able to access our applications server through web dispatcher using HTTPS protocol(error page cannot be displayed), while it is working using http protocol.

we are getting the below error in dev_webdisp of SAP web dispatcher

[Thr 1092684096] Fri May  2 11:31:57 2014

[Thr 1092684096] *** ERROR => RoutePlgAttachToNewServer: IcrAttachToServer(192.168.8.45) for group PUBLIC: rc=4 [route_plg_mt 1144]

[Thr 1092684096] *** ERROR => RoutePlugInStartConn: RoutePlgAttachToNewServer(192.168.8.49): rc=-1 [route_plg_mt 587]

[Thr 1092684096] *** ERROR => IcmConnInitServer: PluginStartConn failed (rc=701) [icxxconn_mt. 1477]

we have already checked in the forum for solution and even tried updating the web dispatcher

We have done the web dispatcher checkconfig

I'm not sure what you are trying to do since you are using parameters only relevant for End-to-End SSL and there is no SSL support in your backend system. Remove the wdisp/HTTPS/* parameters and retry. I assume you intend to terminate SSL on the Web Dispatcher, correct? What is the version and patch level of your Web Dispatcher?

Dear Samuli,

Our web dispatcher is working with out any issues from long period.

Recently we have updated the kernel of the backend system(PI 7.0) from 700 to 720 patch level 600,after upgrading the kernel we are not able to connect to PI server suing HTTPS.

Regards,

Lalitha.
