Hello,
currently i'm connection to oracle using the plain store configuration inside
geoserver. I will try jndi next.
Here is the jmap output after i received a java heap exception:

Betreff: Re: [Geoserver-users] Jave heap space exception on GetFeatureInfo
request
How are you connecting to Oracle? JNDI or plain store configuration where you
give host,
port and connection pool parameters?
It would be quite useful if you could make GeoServer go out of memory and then
issue a
command like:
jmap -histo:live <processid> | head -25
to see what's using the memory. JMap is available in all JDK distributions,
some more
info on how to use it here:
http://docs.geoserver.org/latest/en/user/production/troubleshooting.html#jmap
Cheers
Andrea
