IBM provides tooling and documentation to assist in the understanding, monitoring, and problem diagnosis of applications and deployments running IBM Runtime Environments for Java.
The IBM Monitoring and Diagnostic Tools for Java Dump Analyzer performs automated analysis of system dumps from a Java application.
The IBM Monitoring and Diagnostic Tools for Java - Dump Analyzer (Dump Analyzer) is a tool that helps you determine the cause of a Java application failures using an operating system level dump. It provides individual analyzers which produce specific data in answer to specific questions. It links combinations of these analyzers together to produce a report of any problem causes and the application status.
Using Dump Analyzer will help you easily and quickly diagnose typical problems such as:
Dump Analyzer will attempt to detect and diagnose any problems found in a system dump and if it cannot, it will provide a report containing information from the dump. The report consists of three main sections:
Dump Analyzer uses the Diagnostic Tooling Framework for Java (DTFJ) to access the information in the dump. DTFJ is a technology provided by IBM to read the contents of a system dump and provide access to most process-level and JVM-level entities contained in the dump. Using the DTFJ API, Dump Analyzer is able to access details of process threads, Java threads, Java classes, Java objects, Java monitors etc
Dump Analyzer provides:
Dump Analyzer is delivered in the IBM Support Assistant (ISA) Workbench. ISA is a free software offering which provides a single point of access for the IBM Monitoring and Diagnostic Tools for Java. When new versions of the tools become available ISA notifies you and helps you retrieve the latest version. Using ISA helps you troubleshoot and fix problems in your Java application.
Dump Analyzer is installed within the IBM Support Assistant Workbench.
Dump Analyzer supports the following dump types:
