Impact on Portal if changing IP address of backend systems ?

209 Views

Hi,

Slightly different scenario to the usual "change of ip" address questions.

We have an EP6 Portal used for SSO access to backend R/3, CRM, BW systems.

Does anyone know the impact on the Portal side if the IP address is changed for the backend systems only ?

The Portal system IP address will not change.

The changes requires on the backend systems is already known about,

as they are addressed in notes: 88346, 403708, 757692.

From browsing the forums, I am expecting the Portal will need a restart because

the JVM caches IP addresses.

Refer: Controlling DNS caching in the Java Virtual Machine (i.e. J2EE WAS)

Is there likely to be an impact on SSO, or anything else on the Portal side ?

Many thanks,

Andres
