ID08: WebSphere Message Broker - Enterprise Exception Handling Pattern

Downloadable files


Abstract

This SupportPac provides a pattern and tools to centralize exception reporting throughout the organization for analysis, troubleshooting and data rectification.

Download Description

The Enterprise Exception Handling pattern is to provide a universally accepted method of reporting exceptions in the organization that may be analyzed. Application and system exceptions are reported in a non-standard manner throughout the organization and often reported in logs that are distributed across every node in the subsystem. Hence, the pattern addresses the standardization and centralization of system-wide exceptions.

The pattern looks into the following concepts for the realization of the process:
• Standardization of the Exception format
• Exception reporting through the ESB
• Integration with the Monitoring System
• Centralization and Statistical Analysis of Exceptions
• Testing Exceptions Conditions
