SAP Web Dispatcher: BI-JAVA and BI-ABAP with one Common Hostname and Port?

[LutzR]

Hi all,

on an old BW doublestack we enjoyed the fact that users could address both ABAP and JAVA Stack with a single https://host:port on AS ABAP’s ICM. This way we avoided SSO cookie conflicts with other systems in the same DNS domain (by setting MYSAPSSO2-cookies to host using ume.logon.security.relax_domain.level = 0 according to note 1368384 and profile parameter login/ticket_only_to_host=1). We want a single port because everybody enjoys using standard https port 443 that can be omitted in URLs.

As far as I understand the old functionality everything starting with /sap/ was forwarded to AS ABAP and everything else to AS JAVA. Is this assumption correct?

So with a new BW landscape (of course consisting of two stacks) I would like to achieve this behavior by using a shared SAP Web Dispatcher in front of both systems.

Is configuration really as simple as I derive from:

https://help.sap.com/saphelp_nw73/helpdata/en/49/3db10a19341067e10000000a42189c/content.htm ?

icm/server_port_1 = PROT=HTTPS, PORT=443, SSLCONFIG=ssl_config_0

wdisp/system_0 = SID=ABA, MSHOST=ms_abap, MSPORT=8082, SRCURL=/sap/;/SAML2;/NWBC

wdisp/system_1 = SID=J2E, MSHOST=ms_j2ee, MSPORT=8127, SRCURL=/

wdisp/system_conflict_resolution = 1

Am I missing something or will this work?

(Of course I will have to terminate SSL and reencrypt traffic)

Would somebody please share experience?

Thanks a lot,

Lutz

Hello Lutz,

I believe that will work.

You might want to look at this WIKI page as well for more configuration examples.
