[Geoserver-users] Geoserver heap size, permgen space configuration

GeoServer GeoServer User
1

Hello
I'm using geoserver 2.5 and i'm loading lots of data with .sld files. And i
get java.lang.OutOfMemoryError: Java heap space error. The computer i'm
using has 8gb memory and i want to improve the memory usage of geoserver.

As i understand after some research, i can do this on the wrapper.conf file.
Even i try to update some informations, i could't do it right i think.So how
should i change the wrapper.conf file to obtain higher memory?

By the way, i'm using it on windows as a service.

Any help would be much appreciated.

Mehmet.

Mehmet,

You need to edit the following two sections of that file to work for your specific installation. You can increase the two values based on the amount of memory that you have to use for GeoServer. After you edit the file restart the GeoServer service.

Initial Java Heap Size (in MB)

wrapper.java.initmemory=16

Maximum Java Heap Size (in MB)

wrapper.java.maxmemory=128

You can find information on optimizing the settings at the following link:

http://docs.geoserver.org/stable/en/user/production/container.html

According to the documentation here http://wrapper.tanukisoftware.com/doc/english/props-example-config.html

the settings wrapper.java.initmemory and wrapper.java.maxmemory seems the same thing as the typical java switches -Xmx -Xms with a more friendly name.

Hope this helps.

Thank you Jerome.

I will configure the file as :

# Initial Java Heap Size (in MB)
wrapper.java.initmemory=1024

# Maximum Java Heap Size (in MB)
  wrapper.java.maxmemory=2048

Best Regards, Mehmet

Ciao Mehmet,
I see you on Windows, I would consider using Tomcat and deploy the
GeoServer in it rather than using the provided
binary based on Jetty.
