The geronimo.sh/bat startup script will execute a setenv.sh/bat file if
it is present. See the comments at the bottom of the comment header for
geronimo.sh/bat.
For example, the setenv.sh/bat files can set the GERONIMO_OPTS
environment variable to change the JVM options.
We would want to avoid having two places that JVM options are configured
as that would be confusing and make Geronimo more difficult to support.
Maybe the console could have a page that allows you to add/update/delete
environment variables, which results in the appropriate modifications to
the setenv.sh and setenv.bat files. It would need to be careful with
updating/deleting environment variables, as a user may have inserted
some logic in the script before the environment variable is set (or the
environment variable could be in a number of places in the script due to
logic). Maybe the console would need to detect whether the script has
anything other than the simple setting of environment variables and if
so, prevents you from editing it from the console.
It would be interesting to hear from others whether they think it is a
security issue allowing the console to edit bat/sh startup script files
(could malicious commands be inserted into the startup scripts).

I don't really like the approach of changing the scripts directly.
Can you work on creating such a configuration file and submit a patch
that adds the config file with resonable defaults (or just
commented-out entries) and updates the scripts to use the values from
the config file if they haven't already been defined (in the
corresponding environment variables or something)?
Thanks,

Hi Aaron,
A configuration file is a good idea or changing directly the startup
shell script could be another choice.

Cristian,
How are you envisioning that this would work? For example, currently,
you can start the server with a batch or shell script, or by running
"java -jar bin/server.jar". I don't think any configuration set from
the console could affect the "java -jar" startup method. But it would
be possible for the console to write a config file or something that
the batch or shell startup script read -- a kind of "default JVM
parameters" to be used if the user doesn't manually specify something.
Is that what you have in mind?
Thanks,
Aaron

Hi All,
I wanted to modify the Geronimo's JVM configuration from WEB Console, but
I
could not see any page for this task, I think .. it could be usuful to
have
a portlet to configure the JVM parameters, for example:
Max heap Size
Min heap Size
Boot Classpath (append/preppend)
Debug mode
JIT (on/off)
Verbose GC (on/off)
Java properties (-D)
JVM Arguments (generic)
Thanks.
