One Web Dispatcher, Two Systems

[Former Member]

Dear All

When I config SAP Dispatcher on Windows. I follow by this links http://help.sap.com/saphelp_nw72/helpdata/en/c5/ec466f5544409982c7d3ca29ce1ad3/content.htm but I can't log both system.

1. Accessibility of Message Servers

rdisp/mshost = prdserver

ms/http_port = 8100

1. SAP Web Dispatcher Parameter

wdisp/auto_refresh = 120

wdisp/max_servers = 100

wdisp/shm_attach_mode = 6

icm/HTTP/server_cache_0/http_cache_control = true

1. configuration for large scenario

icm/max_conn = 16384

icm/max_sockets = 16384

icm/req_queue_len = 6000

icm/min_threads = 100

icm/max_threads = 250

mpi/total_size_MB = 500

mpi/max_pipes = 21000

#maximum number of concurrent connections to one server

wdisp/HTTP/max_pooled_con = 2000

wdisp/HTTPS/max_pooled_con = 2000

wdisp/system_conflict_resolution = 2

wdisp/allow_multiple_matching_systems = true

1. SAP Web Dispatcher Ports

icm/server_port_0 = PROT=HTTP,PORT=9999

icm/server_port_1 = PROT=HTTP,PORT=8888

wdisp/system_0 = SID=BIP, MSHOST=prdserver, MSPORT=8100, SRCURL=/irj/portal/, SRCSRV=*:8080

wdisp/system_1 = SID=BID, MSHOST=bipserver, MSPORT=8100, SRCURL=/irj/portal/, SRCSRV=*:9090

When you want to connect two backends to one webdispatcher, you should NOT set these parameters:

rdisp/mshost = prdserver

ms/http_port = 8100

The connection is made by specifying wdisp/system_X.

Another problem with your setup is the ports:

icm/server_port_0 = PROT=HTTP,PORT=9999

icm/server_port_1 = PROT=HTTP,PORT=8888

wdisp/system_0 = SID=BIP, MSHOST=prdserver, MSPORT=8100, SRCURL=/irj/portal/, SRCSRV=*:8080

wdisp/system_1 = SID=BID, MSHOST=bipserver, MSPORT=8100, SRCURL=/irj/portal/, SRCSRV=*:9090

You specify listeners on 9999 and 8888, but route all traffic coming in on 8080 to BIP and all traffic coming in on 9090 to BID.

Since you're listening on 9999 and 8888, there will be nothing on 8080 and 9090. The correct setup would be:

icm/server_port_0 = PROT=HTTP,PORT=9999

icm/server_port_1 = PROT=HTTP,PORT=8888

wdisp/system_0 = SID=BIP, MSHOST=prdserver, MSPORT=8100, SRCURL=/irj/portal/, SRCSRV=*:8888

wdisp/system_1 = SID=BID, MSHOST=bipserver, MSPORT=8100, SRCURL=/irj/portal/, SRCSRV=*:9999

well Windows Server 2003 SP1 is a very bad idea in general.

You should at least run Windows Server 2003 SP2 (plus all available updates for SP2).

Why can't you use the latest version?

There exists a 7.20 version for your Windows release. You should download that Kernel version and extract it somewhere apart from your actual Kernel Dir. You can run the webdispatcher standalone and it is backward compatible. So there should not be any issues reagarding your release 7.00.

Kind regards,

Hi,

As far as I know that SAP Web Dispatcher 7.20 requires, in order to connect two or more systems from one web dispatcher. What version your are running on?

Did you check the trace files of the webdispatcher?

It would be interesting to see what information is provided within those files. May there is a hint why your config does not work.

You should also have a look at this [SAP help page|http://help.sap.com/saphelp_nw72/helpdata/en/b0/ebfa88e9164d26bdf1d21a7ef6fc25/content.htm] regarding your parameter setting for

wdisp/system_conflict_resolution = 2

. Maybe that is the source of your problems.

Kind regards,
