   Setting Up a BEA Tuxedo Application

Distributed applications provide several important benefits. Early business applications were developed to run on one large mainframe computer. Because all computing was performed on a single machine, a failure could bring down an entire system. With the increasing popularity of distributed applications, this threat of system failure is declining.

Another advantage is that by distributing an application, you can group parts of an application logically and position these logical groups in the most effective locations. By creating groups of servers, for example, you can partition a large application into separate, business-specific components of manageable size and optimal location.

A distributed application allows you to do the following:

• Perform data-dependent partitioning

• Manage multiple resources

• Enlarge the client and/or server model

• Obtain transparent access to BEA Tuxedo system services

• Establish multiple server groups

• Use multiple computers simultaneously to do the work of one application, providing better throughput and response time

• Provide for replicated resources for increased availability

Features of a Distributed Application

• Coordination of autonomous actions-Autonomous actions are actions that involve multiple server groups and/or multiple resource manager interfaces. The BEA Tuxedo system enables you to coordinate autonomous actions among separate applications as a single logical unit of work.

• Resilience-When one of many machines fails, the remaining machines continue to operate. Similarly, when one server in a server group fails, the remaining servers continue the work.

• Scalability-Application load or capacity can be increased by:

  • Placing more servers in a group

  • Adding machines to an application and redistributing groups across machines

  • Replicating a server group that resides on one machine, on other machines, and using load balancing

  • Segmenting a database using data-dependent routing for groups that meet specific criteria
