ManagedConnectionFactory Properties

ManagedConnectionFactory properties are specified when a connector-connection-pool is
created. All the properties specified while creating the resource adapter can be overridden in a
ManagedConnectionFactory. Additional properties available only in
ManagedConnectionFactory are given below.
Chapter 4 • Configuring Java Message Service Resources
Default Value Description
The isSameRM method on an
Provider
XAResource is used by the
Managed
Transaction Manager to determine if
the Resource Manager instance
represented by two XAResources are
the same. When RMPolicy is set to
ProviderManaged (the default value),
the JMS provider is responsible for
determining the RMPolicy and the
XAResource wrappers in the Generic
Resource Adapter merely delegate the
isSameRM call to the message queue
provider's XA resource
implementations. This should ideally
work for most message queue
products.
Some XAResource implementations
such as IBM MQ Series rely on a
resource manager per physical
connection and this causes issues
when there is inbound and outbound
communication to the same queue
manager in a single transaction (for
example, when an MDB sends a
response to a destination). When
RMPolicy is set to
OnePerPhysicalConnection, the
XAResource wrapper
implementation's isSameRM in
Generic Resource Adapter would
check if both the XAResources use the
same physical connection, before
delegating to the wrapped objects.
