Make it so Geoserver can configure the JAI tile cache in a sensible manner
--------------------------------------------------------------------------
Key: GEOS-852
URL: http://jira.codehaus.org/browse/GEOS-852
Project: GeoServer
Issue Type: Improvement
Affects Versions: 1.5.0-beta1
Reporter: Andrea Aime
Assigned To: Andrea Aime
Fix For: 1.5.0
The JAI parameters configuration in the Geoserver setting suggest the
default value is 209715200, which I suppose is something around 200MB,
right?
Yeah.
I would suggest to have a setting that is proportial to the max heap
size instead, that is, use something like 50%, so that If I start
geoserver with 64mb the tile cache won't eat all the heap memory.
That is, assuming the tile cache can do that, that is, allocate
X megabytes and keep them no matter what causing an OOM.
The GridCoverage DefaulProcessor already does kind of this. If we gave
JAI too much tile memory it lowers it accordingly to heap memory
(thanks to Martin 
). However I think your idea might work quite
well, we could borrow some code from the DefaultProcessor and
implement your idea.
