SAP 47 Ext 200 - DB on Oracle/SUN, CI and app servers on HPUX

Hello,

I will be installing SAP 47 Ext 200 on Oracle/SUN in preparation for a DB/OS migration. Although I have received detailed information from SAP, I was wondering if anyone had experience with this setup as it relates to performance, potential issues, and/or useful tips on:

1) the database will be an Oracle db on SUN

2) the Central Instance/message server will be HPUX

3) there will be 2 other HPUX application servers

Any insight would be appreciated. Thank you very much in advance,

Nicole Gurnee
