Problem with Web Dispatcher with Double Stack

[Former Member]

We have the latest version of Web Dispatcher - 7.0 with latest patch.

I'm having a problem where I am trying to use the web dispatcher for load balancing in a double stack (ABAP/JAVA) system. The person who did the install pointed the installation to the wrong server (which I assume can be easily changed in the profile). However, on the page where it indicates to activate the SICF services he left the box unchecked (but I checked that necessary ones were activated per note 552286). I now get these kind of errors when pointing to the http message server on a different system (he installed it assuming it was just for portal (java):

[Thr 5] *** ERROR => ICP_StructValue: illegal struct reference: wdisp_host_info.capacityIsFi

xed [icpvalue_mt. 257]

[Thr 5] *** ERROR => caught ICP exception (eval): ICP_StructValue: illegal struct reference:

wdisp_host_info.capacityIsFixed [icpvalue_mt.cpp 257] [http_adm_mt. 1488]

I get the above error when I go to "monitor server" groups in the web dispatcher admin console.

Here is my profile:

SAPSYSTEMNAME = PW4

SAPSYSTEM = 01

INSTANCE_NAME = W01

DIR_CT_RUN = $(DIR_EXE_ROOT)/run

DIR_EXECUTABLE = $(DIR_CT_RUN)

#----

1. Accesssability of Message Server

rdisp/mshost = <fully qualified hostname>

ms/http_port = 8101

1. Configuration for medium scenario

mpi/total_size_MB = 80

1. SAP Web Dispatcher Ports

icm/server_port_0 = PROT=HTTP,PORT=81$$

Any insight is greatly appreciated!!

Dear Thomas,

normally these error message occur when the admin pages do not fit to the

version of the web dispatcher executable..

The best way would be to download the latest version of the web dispatcher and also extract the wdispadmin.SAR package to ensure that the admin pages fit to the executable..

Kind Regards

Thanks Thomas I had the same problem.

I simply uncar the wdispadmin.SAR located in sapmnt/<SID>/exe and it works !!! without restarting the server !

SAPCAR -xvf wdispadmin.SAR

Many ThanksThomas

Hi,

I've never seen this error but some thing seems strange to me :

You use the same port (8101) for the listening port of the web dispatcher and the listening port of the message server of you back office system.

Is it really the case ?

Is PW4 the SID of you web disptcher ?

Is SAPSYSTEM = 01 the sysnr of your web dispatcher ?

I hope that the info of the web disptcher is not mixed up with the back office info ?

Regards,

Olivier
