HTTP load balancing using message server

Hi All,

Currently im a situation where loading balancing is not happing as expected.

the scenario is i have a central instance and a dialog instance. i created a logon group in SMLG and assign only dialog instance to this logon group.

but when i access the below link it also forward my request to Cental instance.

http://FQDN:8101/sap/bc/nwbc

Please advice how should i restrict the logon only to dialog instance using logon group.

Regards

Shanthosh

    Hi Rishi / Rb,

    Thank you so much for your prompt reply.

    Im trying to configure HTTP logon load balancing using message server. unfortunately it is not working as expected.

    i have two instance, one central instance and one dialog instance. when i try to access nwbc through url it always routes to both the server. i have done the below settings

    logon group 'dialog1' has been created and i have assigned only the dialog instance to this logon group.

    ms/http_port is set

    Below service are activated

    sap/public/icf_info

    /sap/public/icf_info/icr_groups

    /sap/public/icf_info/icr_urlprefix

    But still the nwbc access routes to both the server.

    Please advice me if i need to do any addition steps to restrict the logon only to dialog instance.

    Regards

    Shanthosh

    Hi,

    I think that you need to read the below note.

    1040325 - HTTP load balancing: Message Server or Web Dispatcher?

    Thanks

    Dear All,

    I am stuck with logon load balancing functionality. I want to logon load balance HTTP requests using Message server.

    Parameter

    ms/server_port_0 = PROT=HTTP,PORT=81$$ is set and

    The ICF Services sap/public/icf_info/logon_groups and sap/public/icf_info/urlprefix must be activated (transaction SICF),

    are already activated.

    When I give "Logon group" in SICF services and test logon load blanacing its giving below URL.

    http://<message server host>:<ms http port>/<service path>/<service name>

    it should give

    http://<message server host>.<domain>:<ms http port>/<service path>/<service name>

    and with

    http://<message server host>.<domain>:<ms http port>/<service path>/<service name> link logon load balancing works.

    Does anyone have any idea which parameter <domain> is picking and how its working.

    Regards,

    Bond
