Hi Robert,
When you login to the Sametime System Console
https://sametimesystemconsoleserver.acmer.org:8701/ibm/console/
you will find the Sametime System Console section in the left menu at the bottom.
Under [Sametime Prerequisites] -> [ Connect to DB2 Databases ] you will
find the current database connections and you can find which database server is being used.
Cheers, Marco
