Use message server as load balancing instead of web dispacher for XI in HA

45 Views

Hi all!

We are currently upgrading a cluster XI installation from 3.0 to 7.0.

The idea is:

Now: 1 node (central instance)

1 node (database)

Future: 1 node (central instance)

1 node (database + application instance)

So we need some king of load balancing between the two instances.

We already know web dispatcher and all configuration required. However we

were trying not to use it but use the abap/java message server who can also do

the redirect.

However, once the Exchange Profile has been updated, it does not work.

If we change "com.sap.aii.connect.repository.httpport" to "8101". Cache refresh stop working with a "Authorization Error". This is really strange because if I try the very same URL in the explorer and I enter the logon data, I have no problem.

Do you have any experience with this? I mean, is it possible to avoid installing web dispatcher?

Thanks and kind regards,

Encinas.
