[Geoserver-users] Tomcat optimization: CATALINA_OPTS entry

Roger_Andre2 · March 19, 2008, 6:08pm

Hi, I was just wondering if someone could add an actual example of what the CATALINA_OPTS environment variable should look like? The information on http://geoserver.org/display/GEOSDOC/6+GeoServer+in+Production+Environment is excellent, but I had to do a bit of research to figure out how to implement the advice that’s located there. I ended up adding the following line to my .bashrc (this is on a Fedora 8 system), and it works great.

export CATALINA_OPTS=“-server -Xms48m -Xmx256M”

Thanks,

Roger

Hi Roger,

I think there are quite many places where you can put it. I am using centos and starting tomcat with jsvc script:
http://tomcat.apache.org/tomcat-6.0-doc/setup.html (unix daemon)
so the java options are defined in tomcat (jsvc) script.

It can also be put into catalina.sh in $TOMCAT_HOME/bin under JAVA_OPT if you are starting with startup.sh. Probably many other alternatives exists.

What you can put in your java options depends on your java. Here is a good link with plenty of useful sublinks:

http://blogs.sun.com/watt/resource/jvm-options-list.html

If you are concerning of your Tomcat's performance, use jconsole or some other tool for monitoring. Please let me know if I can help more.

Yep,

should be using TomCat Manager and its server status. You may suprise what java you are using and what are the memory settings and so on; anyway if you have tested different versions. Learn to use jconsole. There you have everything you ever need to know about your engine under the hood. At least it's enough for me.

Hi Mika,

Thanks for the information. I had no idea that the settings could be set in so many places.

I was upgrading from 1.6.0 to 1.6.2a and now get the following error:

Cannot register alias 'catalog' for bean name 'data': it's already registered for bean name 'data'

I downloaded and installed the WAR. Any thoughts? David

No, it is not. The steps to have it would be:
a) file a jira issue asking for that (otherwise we'll forget)
b) either:
    - provide a patch for it
    - wait for developers to have a need for it
    - sponsor someone to implement it

Cheers

Justin_Deoliveira · March 25, 2008, 2:18am

Definitely file a feature improvement for it. I could see this fall into the group of "Vendor Options" for labelling. Discussed here:

http://docs.codehaus.org/display/GEOSDOC/LabelingOptions

Andrea: Are all the options listed on that page still relevant?

Most of the are part of the SLD standard so yes, they are. Priority
is a vendor extension, I've never tried to use it, but I'm not aware
of someone intentionally breaking it either, so it should be still
working.

Under high load, we are occasionally seeing what appears to be a deadlock situation. We ran a full thread dump in the Tomcat process and found two threads that appear to be in a deadlock situation. Here are their stack traces: Notice the locks on addresses 0x078fdb20 and 0x07c332b0.

Any thoughts as to what the problem might be or how to get around this? Thanks, David

David R Robison a écrit :

Under high load, we are occasionally seeing what appears to be a deadlock situation. We ran a full thread dump in the Tomcat process and found two threads that appear to be in a deadlock situation. Here are their stack traces: Notice the locks on addresses 0x078fdb20 and 0x07c332b0.

Created a JIRA task:

http://jira.codehaus.org/browse/GEOT-1777

Thanks for reporting,

Martin

If I set SRSHandling to LEAVE, will it not call this code and thus not risk a deadlock? TNX David

No, it will reach the same code using a different path. It's a matter
of time and bad luck, but eventually it will deadlock anyways...

We are about to go into production on a system that makes heavy use of geoserver. Any thoughts as to how to work around this? Any help would be appreciated. TNX David

No idea... it seems to be a bug in the code and has to be resolved
as such... the only thing that might help is a patch.

I am using a PostGIS data store, is it possible to request that the returned features be sorted in a WFS call? TNX David
