[GeoNetwork-users] GeoNetwork 2.4.1 requirements

GeoNetwork GeoNetwork User

Hi all,

What are the current minimum requirements regarding memory for GeoNetwork 2.4?

This page mentions "2MB" RAM, which should probably read "2GB", but is for version 2.0:
http://geonetwork-opensource.org/documentation/tutorial/administration/webinstallreq

Also what JAVA options are you recommending? I'm running GeoNetwork on a Linux box with Apache, Tomcat and Postgres.

I found some requests for recommended production environment characteristics and profiling on Nabble as well, but there has been no answer yet.

Can anyone give me a recommendation?

Cheers,

Hi Michael,
Normally I give the JVM running GeoNetwork 1GB RAM and that works very well. More RAM will allow you to have more parallel sessions without running into memory heap exceptions. This should work under normal loads. By default user sessions were valid for three hours, but I think this has already been reduced to some 30 minutes in GN2.4.
You can see what recommended options for the JVM are used by studying the geonetwork startup file. They are:

java -Xms48m -Xmx512m -Xss2M -XX:MaxPermSize=128m -DSTOP.PORT=8079 -Djava.awt.headless=true

You see that by default it only gets 512MB and a minimum configuration only has 256MB.
Hope this helps, ciao,
Jeroen

Hello folks,

2009/9/14 Jeroen Ticheler <Jeroen.Ticheler@anonymised.com>:

By default user sessions were valid for three hours, but I
think this has already been reduced to some 30 minutes in GN2.4.

Where can I check this setting?

Thank you for the help
Luca

Hi Luca

You can change it in the file install_dir\web\geonetwork\WEB-INF\web.xml:

Look for the next section and change the parameter session-timeout (in
minutes) to the value you need:

    <session-config>
        <session-timeout>180</session-timeout>
    </session-config>

Geonetwork restart should be needed to apply the change.

Regards,
Jose Garcia
