WebAS access via Portal: Web Dispatcher required for load balancing ABAP

39 Views

Hi Folks -

We have EP 6.0 SP18 (Java only, WebAS 6.40, Unix/Solaris). The portal has a CI/SCS and one DI so we have a Web Dispatcher to load balance the portal servers. This works fine (and provides port 80 access).

This portal will provide access to HTTP services from an ABAP WebAS (6.20 with 6.40 kernel, Unix/Solaris). A landscape configuration entry has been added to the portal for this ABAP system. The ABAP system has a CI and multiple app servers, all capable of handling HTTP requests. This will also require port 80 access.

1. Will we need an additional Web Dispatcher to load balance HTTP requests to the 'backend' ABAP WebAS system, or will the portal be smart enough to handle the load balancing itself (perhaps based on the information in the landscape configuration)?

2. If the portal itself handles the HTTP load balancing can you point me to documentation (so I can make sure I have proper configuration)?

3. Are there any changes to this with NW2004s Portal (we plan to upgrade soon)?

Thanks in advance! Jeff
