SNAPPIT DD data set
The SNAPPIT data set contains the CI SNAP dump produced by the OPC utility.
When FULLSTEP=NO and SNAPPIT DD are specified, and if any pointer errors are detected in the area, the CI Map/CI Dump report is produced (by OPC) in the SNAPPIT data set.
When the TYPRUN=RPT keyword, FULLSTEP=YES keyword, and SNAPPIT DD are specified, and if any pointer errors are detected in the area, the following reports are produced in the SNAPPIT data set:
- Pointer Chain Reconstruction report (produced by the Analyze function of FPA)
- CI Map/CI Dump report (produced by OPC and the Analyze function of FPA)
Subsections:
Pointer Chain Reconstruction report
This report shows the following information:
- A list of all pointers to user-specified targets that were detected during the analysis
- CI dump number of the CI dump that contains the user-specified target
This report is produced by the Analyze function of FPA, which is called by OPC internally when FULLSTEP=YES and SNAPPIT DD is specified.
CI MAP/CI Dump report
The CI Map/CI Dump report is used to analyze DEDB area CIs to determine the best way to repair them. The report provides the following information:
- CI dump that is produced during online pointer check
- CI map and CI dump that is produced during in-depth pointer check of the Analyze function of
FPA when FULLSTEP=YES is specified:
- CI map, which is a list of CI headers, all the segments, free space elements, scrap bytes, unknown area, and CI trailer that the Analyze process found in the CI
- CI dump that is logically formatted based on the CI map
The following figure shows an example of a CI Dump report that is produced during online pointer check.
