The WebLogic Server
The WebLogic Server
The WebLogic Server is a standards-based J2EE application server that provides a
foundation for building applications. It must be purchased from BEA Inc. to run on
NonStop servers. The WebLogic server running on a NonStop server includes the
following features:
Load balancing
Fault tolerance
Web services
Network transparency
Legacy integration
Transaction management
Security
Multi-threading
Persistence
Database connectivity
Resource pooling
Development, testing, and packaging facilities.
The WebLogic Server 8.1 SP3 is certified by BEA on HP NonStop servers.
On properly configured HP NonStop servers, the WebLogic Server runs unchanged
just like on other platforms.
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.
•
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
