Unicode WAS 6.40 on 32-bit Windows

[Former Member]

We currently have all of our SAP systems running on Windows 32-bit. We're going to be implementing several applications that will require J2EE, and we will be migrating to Unicode.

1. Is Windows 64-bit practically required for Unicode because of memory addressability? Even for development systems?

2. Some people here are concerned about the 1.7GB limit on heap with 32-bit Windows? Any validity to this concern or is 1.7GB still plenty for the current set of apps from SAP like EP or CRM?

3. Some people seem to be recommending installing Java on separate servers from your ABAP servers. Is there a compelling reason for this or is it safe to use the Java Add-in for ABAP on the same server?

Thanks!

No, 32-bit can be used as well, just pay attention to system requirements for Unicode systems.

One option is to switch /3GB options on Windows, another is to configure more the one J2EE server and it will allow to use 1.7GB's heap for each of them.

We are using both technologies and both are working fine. I don't know any dramatic advantages one against the other or visa versa. I would say it all depends on the system landscape design, you are planning to implement.
