I’ve set up a new Ubuntu cloud server with 2GB RAM.
I also have another server with the same configuration, but running OpenJDK and GS 2.2.1
On my new server I use GS 2.2.4 and Oracle-Java-7.
I’ve mimicked the settings of both servers and all seems to work OK, except for GWC.
When I want to seed a layer I’m getting errors about ‘java.lang.OutOfMemoryError: Java heap space’ in the log.
I’m still a novice when it comes to Ubuntu and Java and it took me a long time and a lot of trial-and-error before I got my other server working. I had hoped using the same settings would help me out.
My question to you all is. What and where do I need to change to prevent heap space errors and get my GWC up and running? Is this a setting in Tomcat7 or in Geoserver/GWC?
Thanks,
Paul
Hi,
http://docs.geoserver.org/stable/en/user/production/container.html
some JVM parameters you might want to try out.

Thanks Imran,
In /usr/share/tomcat7/bin/setenv.sh I have the following:
-server -Xms512m -Xmx1024m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m
-XX:MaxPermSize=256m -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=36000
-XX:+UseParallelOldGC -XX:+UseParallelGC
-XX:NewRatio=2 -XX:+AggressiveOpt
This is working on my first server but not on my new server with GSv2.2.4 and Oracle-Java.
Perhaps I’m not setting it correctly?
On both servers I have installed the native JAI and JAI Image I/O extensions.
I also noticed that tomcat7 is not starting after a reboot of the server. I have to manually start it.
Perhaps I did not install tomcat7 correctly?

This is unrelated to the problems you’re seeing, but I’d discourage using Java 7 with the
GeoServer 2.2.x series, there are a few little things here and there that do not work
as expected due to changes in how the library manages maps (as in, key/value pairs
collections).
The first series that received minimal attention vs java 7 is 2.3.x, even thought the main target
JDK for it is still Java 6

Thanks Andrea,
I can set up a new server with Oracle-Java-6.
What would be the best settings in my setenv.sh file when I have 2GB RAM and 80GB Disk?
On my current server with Oracle-Java-7, I’ve tried changing -Xmx1024m to -Xmx512m and to -Xmx1536m, in both cases I get an out of memory (java heap space).
Do I need to change a different settings to increase the heap space?

Java and I are not best friends

Hum, with so little RAM 512m is probably better, to leave some space for file caching. But I guess the settings are not
being picked up by Tomcat, otherwise you’d not get a OOM so soon

Thanks Andrea,
I did a more searching and it seems I misunderstood what to write in the setenv.sh file.
I deleted all content and paste these lines:
CATALINA_OPTS=“$CATALINA_OPTS -server -Xms256m -Xmx512m”
CATALINA_OPTS=“$CATALINA_OPTS -XX:SoftRefLRUPolicyMSPerMB=36000”
Using ps aux|grep jar I can now see Tomcat is using my settings instead of the default settings.
I’m seeding now (finally)
Thanks for all your help. It were again days I’ve learned a lot.

This is probably worth putting in the documentation somewhere.
This page - http://docs.geoserver.org/stable/en/user/installation/windows/binary.html#setting-environment-variables
and - http://docs.geoserver.org/stable/en/user/production/java.html#production-java
Both say something to the effect of: “For best performance, use Oracle JRE 6 (also known as JRE 1.6) or newer.”
Which implies Java 7 is fine.
For reference - Java 8 is due out later this year - https://en.wikipedia.org/wiki/Java_8#Java_SE _8 - so its probably worth specifying exactly which major version of Java GeoServer best supports.
