Steps for identifying the program or component

Identify the program or component involved with the output from one of the following steps:

1. For output from a batch job, obtain the program name from the PGM parameter on the JCL EXEC statement. In the following example the program name is obtained from the JCL EXEC statement:
   In the following example, the name of a program involved with the output is IKJEFT01. It can be found on the PGM parameter of the EXEC statement:

   //*
   //*====================================================
   //* Batch TSO job (PGM=IKJEFT01)
   //*====================================================
   //IKJEFT01 EXEC PGM=IKJEFT01,REGION=4096K,DYNAMNBR=50
   //*

2. Identify the program or component involved with the output from one of the following:

   • For output from interactive work, use the command being processed to identify the program.
   • For an error message, use the message prefix to identify the program or component or look for the component listed in the message explanation. Look at the preface of any of the z/OS MVS™ system messages books to find the element or component that the message is associated with and the book where you can find the explanation of the message:
     For example, if you have an incorrect message with message number AHL002A, you can tell from the preface of z/OS MVS System Messages, Vol 1 (ABA-AOM) that the message was issued by GTF, and the explanation can be found in the same book:

     Table 1. Example of using the message prefix to identify the component

     Prefix	Component	Book Title	Order Number
     AHL	Generalized trace facility (GTF)	z/OS MVS System Messages, Vol 1 (ABA-AOM), z/OS MVS Dump Output Messages	SA22-7631 SA22-7590

3. For a return or reason code accompanying an abend, see the component listed in the explanation of the code. The following example identifies the component issuing an abend:

   00D
   
       Explanation:  An error occurred during processing of a
   CTRACE or CTRACEWR macro. Register 15
   contains xxnnnnxx where nnnn is a reason code that
   further describes the error.

   Reason Code (hex)

   Explanation

   0001

   For the CTRACE macro, the parameter list version number is incorrect.

   0002

   For the CTRACE macro, the component name either does not begin with an alphabetic or national character, or it contains one or more characters that are not alphanumeric or national characters.

4. For a component of z/OS, continue with Searching the problem reporting databases for an output problem.
5. For an IBM® subsystem or product, continue diagnosis with the subsystem or product.
6. For an installation-provided program, including an installation exit routine, continue diagnosis with that program.
