Using Fault Analyzer
- Introduction
- Real-time analysis
- The Fault Analyzer ISPF interface
- Performing batch reanalysis
- Performing interactive reanalysis
- Performing CICS system abend dump analysis
- Formatting a CICS auxiliary trace data set
- Performing Java analysis
  - Selecting a Java dump data set
    Specification of a Java™ dump data set to be analyzed is done by first selecting File > Analyze MVS Dump Data Set from the Fault Entry List display.
  - Java fault entry reanalysis
  - Displaying the Java information in the interactive report
  - Java event replacement in Fault Analyzer event list
    When an abend includes Java™ events, Fault Analyzer requests a system dump of the JVM. This Java system dump is analyzed by Fault Analyzer using Diagnostic Tool Framework for Java (DTFJ) APIs.
  - Java information reporting limitations
  - Java application samples
    The JCL samples provided in the IDI.SIDISAM1 sample data set demonstrate how to use Java™ and interlanguage calls with Fault Analyzer.

Performing Java analysis

A feature unique to the interactive component of Fault Analyzer is the ability to present information that is related to Java™. The Java™ execution might be under WebSphere® Liberty, CICS®, or Unix System Services on MVS™. Typically, the environment is Java™ calling legacy programs. These topics explain how to:

Set options for Java™ analysis
Select a Java™ dump data set, or an existing Java™ fault entry, for analysis
Display the resulting Java™ information in the interactive report

The steps outlined in the following assume that you have already started the interactive component of Fault Analyzer from an ISPF session.

Note: Java™ analysis is only compatible with the JVMs shown in Fault Analyzer supported application environments.

Setting options for Java™ analysis

The general interactive reanalysis options are also used for Java™ analysis (see Interactive reanalysis options).

An optional IDIJVM DD statement added to the IDIS subsystem start-up JCL allows for a default JVM to be used for performing Java™ analysis (for details, see IDIS subsystem requirements for Java).
