Server-Specific Features
Server-Specific Features
HP provides the following NonStop server-specific features to the WebLogic Server:
•
An XA resource manager for the HP NonStop™ Transaction Management Facility
(TMF) facility so that NonStop server resources can participate in global
transactions coordinated by the WebLogic Server transaction managers. Refer to
Section 6, XA Resource Manager (XARM) for information.
•
An HP NonStop Server Toolkit for BEA WebLogic Server 8.1 SP3 (NonStop Server
Toolkit) containing:
°
A Java XA resource object adapted specifically for the WebLogic Server so
that NonStop server resources can participate in WebLogic Server global
transactions.
°
An XA wrapper to the Java™ Database Connection (JDBC) drivers for the HP
NonStop™ SQL/MX (SQL/MX) database so those drivers can be used in the
WebLogic Server components needing XA-compliant JDBC data sources.
°
Transaction helpers and dummy XA resource objects to be used by the XA
wrappers for the JDBC drivers.
•
The WS Plug-in, which supports stateful dialogs between web clients (usually a
browser) and J2EE application servers. It also supports more sophisticated load
balancing and configuration options. The WS Plug-in also supports web
applications that utilize session-based dialogs. Refer to Section 8, Using the WS
Plug-in for information.
•
Avitek Medical Records (or MedRec) sample application suite that works with the
WebLogic Server. Refer to Section 10, Sample Application for information.
•
Documentation for supporting various software pieces that form the NonStop
Server Toolkit.
Specific Enhancements
•
WebLogic Server clusters use UDP multicast-based communications for cluster
heartbeat monitoring and propagation of the Java Naming and Directory Interface
(JNDI) tree to the members of a cluster.
•
The WebLogic Server transaction manager coordinates global transactions with
branches contracted to TMF through the Java XA resource object. Since the
WebLogic Server usually accesses only TMF protected resources on the NonStop
server, the WebLogic Server transaction manager’s logging and recovery activities
Note. Applications using WebLogic Server must use SQL/MX to access NonStop SQL tables.
Access to these tables is not supported for programs using HP NonStop SQL/MP (SQL/MP).
For information about the differences between SQL/MX and SQL/MP, see SQL/MX
Comparison Guide for SQL/MP Users.
