SAP WEB Dispatcher LoadBalancing

[Former Member]

Hello,

We have a total of 2 instances in our portal infrastrcture and here are

the details:

SAP Portal CI --> EP70 - SP9 - NW2004s (IP: 172.24.102.70) SID: F21

System Number: 21

SAP Portal DI --> EP70 - SP9 - NW2004s (IP: 172.24.102.71) SID: F22

System Number: 22

We are in process of setting-up the SAP WebDispatcher to loadbalance

between the above 2 Portal JAVA stack instances.

We have configured only the SAP Portal CI instance in the SAP

WebDispatcher profile. Here are the profile details:

-

---

SAPSYSTEMNAME = WEB

SAPGLOBALHOST = tybw102010

SAPSYSTEM = 00

INSTANCE_NAME = W00

DIR_CT_RUN = $(DIR_EXE_ROOT)\$(OS_UNICODE)\NTI386

DIR_EXECUTABLE = $(DIR_CT_RUN)

icm/max_conn = 500

icm/max_sockets = 1024

icm/req_queue_len = 500

icm/min_threads = 10

icm/max_threads = 50

mpi/total_size_MB = 80

wdisp/auto_refresh = 120

wdisp/max_servers = 100

icm/HTTP/admin_0 = PREFIX=/sap/wdisp/admin,DOCROOT=E:\usr\sap\WEB\SYS\profile,AUTHFILE=icmauth.txt

icm/server_port_0 = PROT=HTTP,PORT=8100

icm/host_name_full = tybw102010.tyb.kpmgbsc.net

#Portal CI Details

rdisp/mshost = tybw102070.tyb.kpmgbsc.net

ms/http_port = 8120

Here my quesition is, how can I include the Portal DI in the profile, so that the SAP WEB Dispatcher can do LoadBalancing between the Portal CI & DI instances?

Thank you,

Hi Nikee,

the SAP Web Dispacher retrieves the information of the available

backend systems calling the message server configured in its profile.

So per default both of the instances should be taken into account for

load balancing.

You can see the information the Web Dispatcher gets calling

the following URL :

http://msgserver_host:msgserver_port/msgserver

Also you can install the Web Administration of the Web Dispatcher to

be able to see the available backend systems for load-balancing.

Kind Regards
