Application programs are performed on clients while issuing requests to object servers. Then, the object servers send responses to the clients. On the other hand, programs named agents move to object servers where the agents can manipulate objects in a mobile agent approach. If agents complete manipulating objects in the servers, the agents move to other object servers. If an agent conflicts with other agents on an object server, the agents negotiate with each other to resolve the confliction. If the object servers are faulty, agent find another object server where the agent can be performed. Each agent has its own commitment condition like atomic and at-least-one conditions. For example, an agent can commit if the agent successfully manipulate at least one object server. In this paper, we discuss how to perform agents with different constraints on multiple object servers in presence of servers and agent faults. (C) 2003 Elsevier Science Inc. All rights reserved.

In this paper we discuss a general-purpose, portable, and extensible approach to handle comprehensive monitoring information from a Java run-time environment, based on an extension to the On-line Monitoring Interface Specification (OMIS). The main goal of the Java extension to OMIS is to create an interface that will be used to build an OMIS compliant monitoring system as well as to adapt existing tools and to build new ones for monitoring distributed Java applications. The issues covered include enhancements at the specification level. Tools based on this framework are intended to generate problem-oriented requests and handle response information in a uniform way independent of the tools' specifics and the monitoring system's implementation.

The paper presents a concept of an implementation of an extension to the On-Line Monitoring Interface Specification for Java Applications. The extension aims at defining an open interface for providing on-line software development tools. The general-purpose, portable, and extensible approach to handle comprehensive monitoring information from a Java run-time environment is intended to span the existing gap between the needs in Java application development tools and the lack of a uniform environment which provides monitoring support for different kinds of tools, like debuggers or performance analysers. The main goal of the resulting monitoring system is to adapt existing tools and build new ones for monitoring Java distributed applications.

The enterprise systems are shifting toward the open and multi-vendors systems with the stunning spread of the Internet. As a result, the Common object Request Broker Architecture (CORBA dagger) proposed by object Management Group dagger (OMG) is becoming a de facto standard of the distributedsystem. This trend is also spreading to the field of the enterprise system, and the transaction system is no exception to this general trend. OMG is working out the CORBA Transaction Service V1.1 as specifications for transaction on the CORBA, and coexistence of transaction systems among multi-vendors is expected to be further accelerated by a subsequent increase in the number of transaction systems according to this system. This paper discusses the CORBA Transaction Service specifications and WebOTX/S overview.
