[Geoserver-users] Production Config

David_Alda_Fernandez · February 2, 2016, 10:20am

Hi List,

After migrating our GeoServer 2.0.2 instance to the 2.8 version I've got a couple of questions regarding the configuration of GeoServer in a production environment. One thing that confused me was that on my older installation the process tomcat was able to consume up to 2 GB of ram, which is fine as we have plenty of RAM on that server, and to be honest we haven't had any problem, but in the new version I see that the process consumes up to 300 MB and I feel that when loading WMS vector layers it doesn't do as good as it was done by the older version. Perhaps it has to be like that and it's OK so I decided to go for a production tuning for GeoServer.

The first thing I saw is that according to GeoServer documentation (1) the 1.8 java version is not supported, and we installed that version... It's been working but perhaps those problems with 1.8 version were related to our performance problems.. So I decided to downgrade to java 1.7 and point tomcat to that version. But I still feel that GeoServer is not working at his best..

So I need some advice on advanced configuration. So far I've added these parameters to the java options on the apache tomcat monitor..

-server-Xmx2048M-Xms2048m-XX:MaxPermSize=512m-XX:SoftRefLRUPolicyMSPerMB=36000-XX:+UseParallelGC

I don't know if they're really OK. Can someone tell me if they're more or less OK?

My Set up:

Intel Xeon CPU @ 2.0 GHz
8 GB RAM
Window Server 2012 R2 64 bit.

Oracle Corporation: 1.7.0_80 (Java HotSpot(TM) Client VM) -> 32 bit
Tomcat 7 -> 32 bit

1 - http://docs.geoserver.org/stable/en/user/production/java.html#use-supported-jre

Help is much appreciated.

Thanks

Regards,

Agur bero bat,

Hi,

To add more info... I've found that we have several JAVA HEAP SPACE errors in the logs.

How con confirm that the java options are set as I specified in the Tomcat Monitor?

Any ideas to improve our performance?

Thanks in advance.

how come there’s no space between JVM arguments?, like in “-server-Xmx2048M-…” should be “-server -Xmx2048M -…”

Is that just a copy&paste error or is that how you’re actually passing them, cause if it is I doubt they’ll have any impact, or at least I’ve never seen JVM args passed in that way

Hi Gabriel,

Thanks for your response.

I've added this JVM options in the apache monitor in the Java options tab, and apparently, after testing different formats, I have to pass them without blank spaces and new lines... Otherwise the service won't start. And the thing is that I don't know if the parameters are getting set in the OS.

I have tomcat installed as a service in windows Server 2012

I think I've solved it.

It happened that Tomcat was installed as a Windows Service and couldn't get the params through the GUI so I've done it in command line:

"C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\bin\Tomcat7.exe" //US//Tomcat7 --JvmMx=2048M --JvmMs=1024M ++JvmOptions="-Xms1024m" ++JvmOptions="-XX:MaxPermSize=512m" ++JvmOptions="-XX:SoftRefLRUPolicyMSPerMB=36000" ++JvmOptions="-XX:+UseParallelGC"

One strange thing though is that I can't pass the parameter ++JvmOptions="-Xmx2048m" as Tomcat crashes while starting up. I don't know why.

Now it seems that the performance is notably better.

Hope this can help to someone else.

I don't know if they're really OK. Can someone tell me if they're more or less OK?

My Set up:

Intel Xeon CPU @ 2.0 GHz
8 GB RAM
Window Server 2012 R2 64 bit.

Oracle Corporation: 1.7.0_80 (Java HotSpot(TM) Client VM) -> 32 bit Tomcat 7 -> 32 bit

1 - http://docs.geoserver.org/stable/en/user/production/java.html#use-supported-jre

Help is much appreciated.

Thanks

Regards,

Agur bero bat,

In the olden days I recall an effective limit of about 1.3GB heap for 32-bit JVM. Perhaps this is relevant. I have not used a 32-bit architecture for many years (except my phone). But as you note, why would this regress?

One strange thing though is that I can't pass the parameter ++JvmOptions="-Xmx2048m" as Tomcat crashes while starting up. I don't know why.
