Thanks. Will give that a try.

How can I tell, which java engine Tomcat is actually using?

At a CMD prompt I'm getting:

C:\> java -version
java version "1.8.0_71"
Java(TM) SE Runtime Environment (build 1.8.0_71-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.71-b15, mixed mode)

If you have a utility that shows what open files the Tomcat process has, that would work. Alternatively, get the Manager application running and see what information it provides under the Server Status screen.

That made me ask myself, whether the parameters and settings I can see and set through the manager (tomcat6w.exe) are those that the
Windows7 service really "sees" at startup.

Would like to have added -Xmx768m to the startup parameters. Looking into the registry HKLM\System\CurrentControlSet\Services\tomcat6 I can only see the ImagePath that is started ("c:\Program Files\Apache_Group\Tomcat_6.0.39\bin\tomcat6.exe" //RS//Tomcat6), the paramters
Key is empty.

Or does tomcat6w write these parameters elsewhere?


Sorry, discard my question above. I forgot for the moment that -Xmx is a Java parameter, not Tomcat. Nonetheless would be interesting to know, where the configurator puts its parameter settings and
how one can control whether the jvm parameters are really effective.
