Solr memory: CATALINA_OPTS in setenv.sh ?

[Bruno Mannina <bm...@free.fr>]

Dear users,

I try to know if my add in the setenv.sh (which I need to create because 
it didn't exist) file has been set but when I click on the link Java 
Properties on Admin Solr web page
I can't see the variable CATALINA_OPTS.

In fact, I would like to know if my line added in the file setenv.sh is ok:
|CATALINA_OPTS=||"-server -Xss7G -Xms14G -Xmx14G $CATALINA_OPTS 
-XX:+UseConcMarkSweepGC -XX:NewSize=7G -XX:+UseParNewGC"|

my setenv.sh file contains only this line (inside /usr/share/tomcat6/bin/).

How can I see if memroy is well allocated ?

Other question: is |*-XX:NewSize=7G* is ok?|

I have 24Go Ram (14G ~60%)

Check your cores' "status" page and see if you're running the
MMapDirectory (you probably are.)

In that case, you probably want to devote even less RAM to Tomcat's
heap because the index files are being read out of memory-mapped pages
that don't reside on the heap, so you'd be devoting more memory to
caching them if you freed it up by lowering the heap.

I changed the method, I edited the file tomcat6 in /etc/init.d and I 
modify the JAVA_OPTS var to:
JAVA_OPTS="-server -Djava.awt.headless=true -Xms14G -Xmx14G"

Do you think it's correct if I have 24Go Ram?
Do you think something is missing ? like Xss or other ?

I found many google pages but not really a page that explain how to 
choose the right configuration.
I think there isn't a unique answer to this question.

it seems there are several methods to adjust memory for JVM but what is 
the best ?
