- 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.
- 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.
- Using a map of the LPA and the instruction address,
identify the name of the module that was in control when the abend
occurred.
- 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
- 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
- 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.
