Java Support; Xa Support - HP Reliable Transaction Router Getting Started

Java Support

RTR clients and servers can be Java applications that obtain
the benefits of high availability, fault tolerance and scalability
provided by RTR. RTR clients and servers employing Java
technology use standard Java and J2EE interfaces for
transaction management, data input/output, and database
access.
For additional information, see the JRTR Getting Started
manual and associated online documentation.

XA Support

Within its C API, RTR provides the capability of using the XA
interface to work with XA-compliant database systems. The XA
interface is part of the X/Open DTP (Distributed Transaction
Processing) standard. It defines the interface that transaction
managers (TM) and resource managers (RM) use to perform the
two-phase commit protocol. (Resource managers are underlying
database systems such as ORACLE RDBMS, Microsoft SQL
Server, and others.) This interface is used by TM-to-RM
exchanges to coordinate a transaction from within an application
program.
If your database application supports XA, you have less to
implement in your application environment; use of XA can also
increase the portability of your application.
For details on using XA with RTR, refer to the HP Reliable
Transaction Router C Application Programmer's Reference
Manual and the HP Reliable Transaction Router Application
Design Guide.
