Abend or wait/loop type-of-failure

  1. For ABEND types-of-failure, the system might have issued message IEC999I, identifying the module in which the error occurred. If this occurs, go to Step 5 to determine if it is a DADSM module.
  2. Using the PSW from the formatted part of the dump obtained earlier, or from the symptom dump (summary) information in the system job log, extract the data in the last four bytes of the PSW. These bytes contain the address of the instruction that follows the last instruction executed before the abend.
  3. Using a map of the LPA and the instruction address, identify the name of the module that was in control when the abend occurred.
  4. If the module name begins with the letters ICV, CVAF is the failing component. Locate the CVAF module name in Table 1 and record the related function and subfunction on the Keyword worksheet as modifier keywords.
    Example: If the module name is ICVCMB00, specify the keyword as follows:
    ICVCMB00
  5. Table 1 contains a complete list of DADSM module names and their related functions and subfunctions. If the module name you identified in Step 1 or Step 3 is in the list, the subcomponent is DADSM. Record the function and subfunction on the Keyword worksheet as modifier keywords.
    Example: If the module name is IGC0002G, specify the keyword as follows:
    IGC0002G
  6. Use the Component Identification Keyword 5695DF133 to develop a keyword string for the DADSM/CVAF subcomponents. Include the suspected module name in the keyword string. The problem might have been previously reported with the same module name. Code the string as follows:
    5695DF133 ABEND0C4 ICVCMB00
    If the search keyword string does not yield usable results, and if the error might exist outside this component, you can broaden the search by deleting the component identification keyword. Build a keyword string containing only the abend code and the module name as:
    ABEND0C4 ICVCMB00
    This keyword string might yield a previously reported problem (and its fix) in some subcomponent other than DADSM/CVAF.
