Having read a number of posts & S-Notes, I found that Web Dispatcher 7.2 is capable of routing between multiple SAP instances.
But despite having troubleshooted, I am unable to make it work. I have two separate installations ERP & Portal on the same host, but my web dispatcher only routes to one of them at the same time. Simultaneous access to these 2 systems is not possible either with URL or Port control procedure mentioned at url http://help.sap.com/saphelp_nw72/helpdata/en/c5/ec466f5544409982c7d3ca29ce1ad3/frameset.htm
Can anyone point an error in my below mentioned configuration of web dispatcher file.
I want requests on port 8853 of my web-dispatcher to be routed to system DEV &
the requests on port 8843 of my web-dispatcher to be routed to system DEP
"
rdisp/mshost = sapdeverp
ms/http_port = 8100
icm/server_port_0 = PROT=HTTP,PORT=8853
icm/server_port_1 = PROT=HTTP,PORT=8843
wdisp/system_0 = SID=DEV, MSHOST=sapdeverp, MSPORT=8100, SRCSRV=*:8853
wdisp/system_1 = SID=DEP, MSHOST=sapdeverp, MSPORT=8102, SRCSRV=*:8843
"
Can we mention multiple message servers instead of single message server "rdisp/mshost = sapdeverp
ms/http_port = 8100" ?
Any suggestions ?
Hi.
You have to remove the first two lines from webdispatcher profile and system respective values for MSHOST parameter :
rdisp/mshost = sapdeverp
ms/http_port = 8100
icm/server_port_0 = PROT=HTTP,PORT=8853
icm/server_port_1 = PROT=HTTP,PORT=8843
wdisp/system_0 = SID=DEV, MSHOST=<Message server host of DEV system>, MSPORT=8100, SRCSRV=*:8853
wdisp/system_1 = SID=DEP, MSHOST=<Message server host of DEP system>, MSPORT=8102, SRCSRV=*:8843

Hi,
I have not yet tried it but your configuration does not seem logical to me :
I would delete these 2 lines
rdisp/mshost = sapdeverp
ms/http_port = 8100
because they seem designed for usage with a single Message server.
I would keep these 2 lines
wdisp/system_0 = SID=DEV, MSHOST=sapdeverp, MSPORT=8100, SRCSRV=*:8853
wdisp/system_1 = SID=DEP, MSHOST=sapdeverp, MSPORT=8102, SRCSRV=*:8843
which define both message servers.

Olivier

Very right in mentioning this point coz myself have been confused over it but if I remove these lines & execute the -checkconfig:
then it states as below:
Checking SAP Web Dispatcher Configuration
=========================================
maximum number of sockets supported on this host: 8192
Server info will be retrieved from host: : with protocol: http
Checking connection to message server...
ERROR: Connection to message server failed: NIESERV_UNKNOWN

-
More over accessing the servers give the following error:"

I have tried this actually, even tried the option ms/server_port_0 & 1 to replace ms/http_port but it didnt work either.
Any more ideas.. ?
Sorry I read note https://service.sap.com/sap/support/notes/908097 wrong.
Webdisp 7.20 is supported for all connected systems <= 7.20
My fault
Cheers,
