Distributed Object Infrastructure Tpbroker V3

Distributed Object Infrastructure nt TPBroker V3

A business-critical k distributed object environment is realized.

-e/

The distributed object environment provides unprecedented flexibility for systems and improves productivity of application development. TPBroker is a distributed object infrastructure that is compliant with CORBA®, the industry standard specification for distributed object environments, and enables you to manage objects and control inter-object communication. Also, TPBroker provides a transaction function that enables you to connect an intra-enterprise system to the Internet to construct, for example, flexible transaction systems that offer EC services to various clients. CORBA: Common Object Request Broker Architecture EC: Electronic Commerce

Suitable for users who need to: Construct a new system connected to an existing system. Re-construct an intra-enterprise system with use of the Internet. Integrate scattered application programs into a new system.

TPBroker: Features

TPBroker supports flexible business systems, based on a distributed object environment

To adapt enterprise systems to rapidly Open system changing business environments, in addition to prompt construction of new systems and highly productive, reliable, and high performance Application infrastructure Easier system/AP based on industry-standard construction enabled by application development, enterprise specifications parts assembly

systems require flexible configurations Enterprise information supporting improvement of reusability systems adaptable to changing business realized by adoption of industry environments standards, linkage with existing systems, and multi-platform support. System Development Application management environment framework environment Internet System linkage infrastructure Host system

TPBroker supports such changing business environments excellent flexibility, enable highly productive application by providing a distributed object environment compliant development, and improve reusability of application with the industry-standard Common Object Request Broker programs. Also, TPBroker enables flexible system Architecture (CORBA®) specification. By using distributed construction through multi-platform and multi-language object technology, TPBroker can provide your system with support and collaboration with Hitachi's middleware.

Object environment for C++ and Javaª Multi-platform support TPBroker supports CORBA®-compliant TPBroker supports HP-UX, Solaris, AIX®, and Windows®. JavaTM/C++ language mapping, so you can use these languages to develop objects. Connectivity with other ORB products Supporting the IIOPTM specified by OMGTM CORBA® 2.1, Flexible scalability TPBroker can connect with other ORB products.

Providing an operation support function for assistance to mission-critical systems Automatic recovery from Automatically restarted when Global startup/termination/ a failure occurs monitoring of processes system/application failures Even if a system failure occurs, TPBroker automatically recovers from the failure and restarts the TPBroker TPBroker system. Also, in case of application program failures, Process Failure Process 1 TPBroker automatically recovers transactions. detection Down Process 2 Starting/ Restart terminating/ Global control of multiple processes monitoring Using TPBroker, various processes such as DBMSs and Process 3 processes application programs can be started, terminated, and monitored all at once. You can operate several independent subsystems as if they were a single system. DBMS: DataBase Management System

2 Enabling transaction processing in a distributed object environment

Function for CORBA¨ OTS TPBroker configuration TPBroker performs transaction processing compliant ® with CORBA OTS, and can synchronize updates of TPBroker client TPBroker multiple databases such as in a distributed database ORB ORB OTS for clients OTS environment. Also, even if a failure occurs during transaction processing, it performs rollback (cancellation Client Server of all changes during transaction processing) consistently object object and automatically. XA SQL DBMS Linkage with resource managers Client DB via the XA interface TPBroker supports the XA interface as well as the OTS Server interface. Therefore, even with a resource manager that does not support OTS, it can synchronize transaction processing. OTS: Object Transaction Service

TPBroker OTM enables you to apply the distributed object environment to large-scale mission-critical systems

With the expansion of distributed object systems and the Third-party ORB clients TPBroker clients adoption of CORBA® as an industry standard protocol, distributed object environments are becoming widely adopted as enterprise systems. When a distributed object environment is applied as an intra-enterprise backbone Connection multiplexing system, stability of the system and improvement of Server throughput are important points. TPBroker Object TPBroker OTM Objects for clients Transaction Monitor (OTM) provides advanced functions that support such large-scale mission-critical systems. With a multi-thread function that facilitates parallel processing, Scheduling and load Queue balancing of requests queue-assisted flow control and a load balancing function, for processing TPBroker OTM enables system construction that requires

scalable and stable performance. Server Server object object pool function Extended functions for stable performance TPBroker OTM provides a load balancing function, Advanced function for reliability a queue-assisted scheduling function, and a server object TPBroker OTM's time monitoring function is useful to pool function to ensure stable performance. detect a failure quickly and isolate it. Advanced function for connection Advanced function for connection with multiple clients with third-party CORBA¨products A connection multiplexing function enables Even third-party ORB clients can use the functions of aggregation of connections from clients.
