[Geoserver-users] close wfs transaction for out of memory error

GeoServer GeoServer User

Hi everyone,

In my project I HTTP POST geoserver’s wfs with the following code snippet ( i cut out some things)

<

wfs:Transaction service=“WFS” … >wfs:Insert<cite:tracks >cite:guid…</ cite:guid>cite:the_geom<gml:Point srsName=“urn:EPSG:geographicCRS:4979”><gml:coordinates decimal=“.” cs=“,” ts=" ">…,…,…</gml:coordinates ></gml:Point></cite:the_geom ></cite:tracks></wfs:Insert></ wfs:Transaction>

and now my server is getting an out of memory error, i know that this means there is not enough memory to hold all the objects created. How do i close the transaction in the xml when i am finished with it?

Hi Dominique,

It is a very large insert?

I notice your GeoServer is configured to use "FileStrategy". While it is
the safest strategy, it is not great for performance as shown below with
the huge array allocation. YOu might confider changing it to
"PartialBufferStrategy". This can be done in the web.xml file. Are you
running jetty out of the box or in another web container.

ok.. .so you if you find the web.xml for geoserver and change the
"serviceStrategy" context parameter to "PARIAL_BUFFER" it could very
well do the trick.
