DBPools with J2EE 6.20

Hi,

I want to create a new DBPOOL in SAP J2EE 6.20 using the Engine Administrator. According to the "Administration Manual" there should be three buttons on the "runtime" tab: add, remove and change. The only buttons I can see are: start/stop, remove and change. But even change does not work 😔

Any ideas what I'm doing wrong? I really would appreciate help!
