Server-Specific Features
Server-Specific Features
HP provides certain NonStop server-specific features to the WebLogic Server:
•
An XA resource manager for the NonStop Transaction Management Facility (TMF)
facility so that NonStop server resources can participate in global transactions
coordinated by the WebLogic Server transaction managers. For more information,
see Section 6, XA Resource Manager (XARM).
•
A NonStop Server Toolkit for BEA WebLogic Server 9.2 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 for Java Database Connection (JDBC) drivers for the NonStop
SQL/MX database so that the drivers can be used in the WebLogic Server
components needing XA-compliant JDBC data sources.
°
transaction helpers and dummy XA resource objects that will be used by the
XA wrappers for the JDBC drivers.
•
Avitek Medical Records (MedRec), a sample application suite that works with the
WebLogic Server. See Section 9, Sample Application.
•
Documentation supporting other software that form the NonStop Server Toolkit.
Enhancements
WebLogic Server has been enhanced to include:
•
UDP: 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.
•
Transaction Manager: The WebLogic Server transaction manager coordinates
global transactions with branches contracted to TMF through the Java XA resource
object. Since the WebLogic Server accesses only TMF protected resources on the
NonStop server, the WebLogic Server transaction manager must be efficient in
logging and recovery activities. To this end, the TMF product has been enhanced
to support one-phase commit optimization for imported branches.
•
SQL/MX SPR 2.2: SQL/MX SPR 2.2 is HP’s next generation relational database
management system designed for business-critical applications. SQL/MX brings
traditional NonStop fundamentals—high availability, scalability, reliability, and
parallel processing—to a distributed database.
Note. Applications using WebLogic Server must use SQL/MX to access NonStop SQL tables.
Access to these tables is not supported for programs using 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.
