Sample 4 (IDISJAV4): IMS Java batch processing sample
The JCL in sample IDI.SIDISAM1(IDISJAV4) demonstrates how to use Fault Analyzer with IMS™ Java™ batch processing (JBP) regions. In the sample, IMS calls a Java program, which in turn calls COBOL and assembler programs.

Using Fault Analyzer
- Introduction

- 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.
    - Sample 1 (IDISJAV1): Enterprise PL/I invoking Java in batch
      The JCL in sample IDI.SIDISAM1(IDISJAV1) demonstrates how to use Fault Analyzer when Enterprise PL/I invokes Java™ in batch. It includes Java calling an Enterprise PL/I DLL that is located in a PDSE data set member.
    - Sample 2 (IDISJAV2): Enterprise COBOL invoking Java in batch
      The JCL in sample IDI.SIDISAM1(IDISJAV2) demonstrates how to use Fault Analyzer when Enterprise COBOL invokes Java in batch. It includes Java calling an Enterprise COBOL DLL that is located in a PDSE data set member.
    - Sample 3 (IDISJAV3): 64-bit Enterprise PL/I invoking Java in batch
      The JCL in sample IDI.SIDISAM1(IDISJAV3) demonstrates how to use Fault Analyzer when 64-bit Enterprise PL/I invokes 64-bit Java™ in batch. It includes Java calling an Enterprise PL/I DLL that is located in a PDSE data set member.
    - Sample 4 (IDISJAV4): IMS Java batch processing sample
      The JCL in sample IDI.SIDISAM1(IDISJAV4) demonstrates how to use Fault Analyzer with IMS™ Java™ batch processing (JBP) regions. In the sample, IMS calls a Java program, which in turn calls COBOL and assembler programs.
    - Sample 5 (IDISJAV5): C++ program invoking Java in batch
      The JCL in sample IDI.SIDISAM1(IDISJAV5) demonstrates how to use Fault Analyzer when using a 31-bit or 64-bit C++ program to invoke Java™ in batch. It includes Java calling a C++ DLL located in a PDSE data set member.
    - Sample 6 (IDISJAV6): Call a Java batch application with the Fault Analyzer wrapper utility
      The JCL in sample IDI.SIDISAM1(IDISJAV6) demonstrates how to use the Fault Analyzer Java™ wrapper utility to invoke a Java class with a main() method within a try-catch block. Unhandled exceptions are automatically caught and fault entries are created using the Snap.dump() method.

Sample 4 (IDISJAV4): IMS Java batch processing sample

The JCL in sample IDI.SIDISAM1(IDISJAV4) demonstrates how to use Fault Analyzer with IMS™ Java™ batch processing (JBP) regions. In the sample, IMS™ calls a Java™ program, which in turn calls COBOL and assembler programs.

The sample uses the IMS™ installation verification program (IVP) program specification block (PSB). Ensure that the PSB is started before running the sample. If the PSB is stopped, abend 0456 occurs instead of the expected abend U0123.

These are the sample results expected in the Fault Analyzer report:

The report includes information about the COBOL program, the assembler program, Java™, and IMS™.
The synopsis section displays the COBOL source and variable information.
In the event summary, the IMS™, Java™, COBOL, and assembler calls appear in a single overview.
For the assembler event, source-code information is obtained from the assembler ADATA compiler option.
