Agenda Getting started Get hands
dirty Q&A © 2011 SAP AG. All rights reserved. 2
3.
Getting started Few assumptions You’ve
passed beyond “Hello World” in Java Hello World apps tend not to require too much memory You’ve gotten an OutOfMemoryError at least once in your life :) You’re proficient already with Garbage Collection Attended the previous BGOUG event GC session © 2011 SAP AG. All rights reserved. 3

Getting started Memory analyzer
basics Works with heap dumps – live snapshots of: © 2011 SAP AG. All rights reserved. 4
5.
Getting started How to
get a heap dump Non-Interactive -XX:+HeapDumpOnOutOfMemoryError On Demand JDK1.4.2_12+ and -XX:+HeapDumpOnCtrlBreak JDK6 and JConsole or VisualVM On IBM VMs -Xdump:system:events=throw,filter=java/lang/OutOfMemoryError, request=exclusive+prepwalk More… http://wiki.eclipse.org/index.php/MemoryAnalyzer#Getting_a_Heap_Dump © 2011 SAP AG. All rights reserved. 5
6.
Getting started Shallow vs.
Retained heap Shallow heap is the memory consumed by one object Retained set of X is the set of objects that will be garbage collected if X is garbage collected Retained heap of X is the sum of shallow sizes of all objects in the retained set of X, i.e. memory kept alive by X Set of elements Retained Set C C, F, G, J K K C, K C, F, G, J, K, I © 2011 SAP AG. All rights reserved. 6
7.
Getting started Dominator tree An
object x dominates an object y if every path in the object graph from the start (or the root) node to y must go through x. In the dominator tree each object is the immediate dominator of its children, so dependencies between the objects are easily identified. © 2011 SAP AG. All rights reserved. 7

Getting started Dominator tree ©

Getting started Java references
– java.lang.ref Softly reachable Created Initialized Strongly reachable Finalized Weakly reachable Soft reference Phantom reachable GC will try to preserve the object Will collect it prior to throwing OutOfMemoryError Weak reference GC is free to reclaim the object. Phantom reference Track object collections © 2011 SAP AG. All rights reserved. 9
