MAT(Memory Analyzer) Querying Objects from a Heap Dump…

I happen to use the Memory Analyzer built-in Object Query Language (OQL) on heapdump recently, which I find it very useful.

These are the some of the queries I used while looking into jms connection leak in customer application.

SELECT toString(clientAddress.value) AS s FROM weblogic.jms.frontend.FEConnection

SELECT toString(clientAddress.value) AS s FROM weblogic.jms.frontend.FEConnection WHERE (toString(clientAddress.value)="/")

There is good blog on MAT Object Query Language (OQL) at
