Data sets used for interactive reanalysis

When performing interactive reanalysis through the ISPF interface, pre-allocation is performed as required for any Fault Analyzer compiler listing or side file data sets that were used in real time. Allocations are performed for Fault Analyzer data sets if they were explicitly included in the real-time JCL, or supplied through the DataSets option or an Analysis Control user exit. These data sets are used in the reanalysis in an attempt to recreate the same execution environment as were used in real-time.

DataSets options that are specified via the IDIOPTS user options file or the PARM field cause those data sets to be logically concatenated to the data sets from the real-time execution.

If the Display panel to alter allocated data sets option on the Interactive options display is set to Y (see Interactive reanalysis options), then it is possible to make changes to the real-time data set specifications before initiating the reanalysis. Also, any data sets that were used in real time but do not exist in the reanalysis environment, or data sets with READ access prohibited, are identified by a comment as shown in the following example for IDILCOB:

//* The following IDILCOB data set is unavailable:
//*        DD DISP=SHR,DSN=D01.COBOL.LISTINGS
//* The following IDILCOB data set is READ protected:
//*        DD DISP=SHR,DSN=CTEST.PROTECT.LISTINGS

Note: If the GenerateSavedReport option is in effect, then all data set or path names that were used during real-time processing will automatically be included, even if these have been deleted from the pseudo JCL display before performing reanalysis.
