The Partition and its services
2PC Transaction Service
The Two-Phase Commit (2PC) Transaction Service exists provides a
complete recoverable solution for distributed transactional CORBA
applications. Implemented on top of the VisiBroker ORB, the 2PC Transaction
Service simplifies the complexity of distributed transactions by providing an
essential set of services, including a transaction service, recovery and logging,
integration with databases, and administration facilities within one, integrated
architecture.
Management
The Borland Management Service encompasses a set of Management Agents
which communicate with a Management Hub. The Hub is installed on a single
host in your network from which you carry out management tasks such as
clustering. The Management Hub lets you monitor and control resources
installed on the local host on which Borland Enterprise Server is installed.
Note Borland Deployment Op-Center (purchased separately) provides the ability to
manage distributed resources installed on remote hosts with network facing
services.
The Partition and its services
A Partition is an application's deployment target. The Partition provides the
J2EE server-side runtime environment required to support a complete J2EE
1.3 application. While a Partition is implemented as a single native process, its
core implementation is Java. When a Partition starts, it creates an embedded
Java Virtual Machine (JVM) within itself to run the Partition implementation
and the J2EE application code.
Partitions are present in each BES Edition and product but they host less
diverse archives in the Web Services, Team and VisiBroker Editions. This
section describes the full-featured functional Partitions offered in the full
Borland Enterprise Server. Each Partition instance provides:
