Your Java Virtual Machines, in which your applications are running their code, should be monitored if it does not contain memory leaks. To find these memory leaks, you can use Enterprise Manager 12c to take and analyze snapshots of the JVM heap. You can do a live Heap Analysis or perform a snapshot to analyze the garbage collector of the JVM. You can also compare a snapshot with earlier taken snapshots, and isolate object that consume a lot of memory.
