+is the default statement batching implementation. OPENJPA also
+provides another update manager
+org.apache.openjpa.jdbc.kernel.BatchingOperationOrderUpdateManager for the
+statements that required ordering. You can plug-in this update manager through
+the "openjpa.jdbc.UpdateManager" property. Or you can plug-in your own
statement batching implementation by providing the implementation that extends
-from AbstractUpdateManager or ConstraitUpdateManager. Add this implementation
+from AbstractUpdateManager, ConstraitUpdateManager or
OperationOrderUpdateManager.
+Add this implementation
class as a property in the persistence.xml file. For example, a custom
statement batching implementation mycomp.MyUpdateManager extends
ConstraitUpdateManager. You specify this implementation in the persistence.xml
