No real problem actually - I always try to install the minimal amount of
features/options/modules that we really need - this consumes less resources
(memory, diskspace), takes less time to patch, and what doesn't get
installed, can't get broken. I know that Oracle recommends to install JVM,
Intermedia, and XML db (they are selected by default).
So my question is what are the consequences of not installing JVM ?
Regarding the dbconsole : i'm referring to the stand-alone database control
that is started up with the command "emctl start dbconsole" on the server,
and accessed by a web browser on my PC (http://...:5500/em).
So NOT the Java-based Enterprise Manager Console !
Dbconsole is running fine, and I didn't install OAS, or JVM with the
database ...

Note : i'm talking about JVM ** inside ** the db, not JVM as part of a
stand-alone installation on a server or client PC.
