Web Dispatcher Configuration.

[Former Member]

Hi,

1)Our srm server is connected to portal and end-users are using portal to connect to it. Srm server has another 2 other application server for load balancing.

As Load balancing is not happening we are getting ITS memory bottle neck issue.

We have installed Webdispatcher for load balancing but I have confusion how will be connectivity Portal --> SAP Web Dispatcher --> SRM.

2) C:\usr\sap>sapwebdisp.exe -checkconfig pf=c:\usr\sap\sapwebdisp.pfl

Hi,

Check SAP Note 538405 - Composite SAP Note: SAP Web Dispatcher.

Thanks

As Load balancing is not happening we are getting ITS memory bottle neck issue.

You need to define a group in SMLG which includes all those application servers running web services that will be used in load balancing. Once you have defined a group then in SICF, select the service being used in Portal, choose Display/Change and set the group under "Service Data" -> "Load Balancing". Now when that particular service is accessed it will be load balanced amongst all application servers in the group.

Hi Mazher,

You have configured logon groups through SMLG and connected web dispatcher. The SAP web dispatcher will take care of load balancing.

How did you conclude the load balancing is not happening ?

Cheers....,

Make sure all services under /sap/public/icf_info in SICF are active.
