I'm in process of serving out some large aggregated datasets (5 - 8GB) with
Thredds WMS. I consistently experience "OutOfMemoryError: Java heap space"
error when making WMS requests. On my test machine, I've allocated -Xmx1536m to
Tomcat and experimentally Thredds is able to serve about 1GB aggregated
By digging through the Dataset Aggregation and Memory related topics on the
list, I've found out that the general suggestions are to allocate more memory
to Tomcat such as: -Xmx4g
One post mentioned that "Thredds does everything in memory".
Can somebody please advise how much memory I should allocate to Tomcat for the
8GB dataset? I'm afraid I have to secure more than 8GB memory.
And what is the best practice to serve out the large datasets on Thredds in
Regards and thanks,
