I am using oracle spatial 18.104.22.168 g.
I am getting out of memory exception on a process.
I analyzed the heap dump using OOMemory analyzer and figured out oracle.jdbc.driver.T4CPreparedStatement keeping 73% of the heap space.
Is oracle expanding the SPARQL queries in java side or keeping the results in cache.
How to solve it ?
We will need a re-producible test case (preferably small) to figure out why you are getting out of memory. You can send it to Oracle Support or email me at alan dot wu at oracle dot com.
Jena Adapter does not cache SPARQL query results on the Java side. The T4CPreparedStatement is not even in Jena Adapter's
code path or RDF's code path.
