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.

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.
    - 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 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.

These are the sample results expected in the Fault Analyzer report for the SNAP dump call:

The event summary includes only Java™ events with class and method information.
The individual Java™ events include source code but no Java™ variable information, because the Java™ virtual machine (JVM) does not provide a mechanism to obtain variable information.

These are the sample results expected in the Fault Analyzer report for the PL/I abend:

The synopsis section includes the source code information from the PL/I program and variable declarations and values.
Because the PL/I code was compiled with TEST(SEP) option, the PL/I source code information is obtained from SYSDEBUG.
The event list includes both the PL/I events and the Java™ events in a single view. For Java™, the class and method names are shown only during reanalysis. (The information is not available to the real-time report.)
In the Java™ events, both source code information and variable values are displayed. When a variable name is not available to the Diagnostic Tool Framework for Java™ (DTFJ) API, the variable address is reported instead.
