[smila-user] Blackboard can't handle BIG attachments
|
Hi,
when testing SMILA with more and more big files, the following exception
flew when adding attachments to a record:
2012-02-16 19:29:04,192 ERROR [ODEServerImpl-1
] vpu.JacobVPU - Method "run"
in class "org.apache.ode.bpel.rtrep.v2.EXTENSIONACTIVITY" threw an
unexpected exception.
java.lang.OutOfMemoryError: Java heap space

This happened while adding the 5th Attachment to a Record, each roughly
about 55 MB in size. As the work-around is quite straight-forward (use
temp files and just use an attribute with the created filename), I can
work around this issue easily. However, does this fit into the design of
SMILA? Are there any other thoughts about it? As I will need to handle
more data which in total is significantly bigger than this changing the
heap size is not really an option.
Best,
Stephan
