The Source option is used to control whether real-time source code analysis is to be performed:
  • If Source is in effect, then real-time source code analysis is performed as usual. This value is the default.
  • If NoSource is in effect, then Z Abend Investigator does not access any compiler listings or side files and source code information might not be available in the real-time report. Assuming that either a minidump or an associated MVS dump data set data set has been written, then it is still possible to provide source code information by performing reanalysis against the history file entry.

    This option might be useful as a means of improving real-time analysis performance in installations where a large number of compiler listing or side file data sets are used, and where performing reanalysis to provide the extra source code information is an acceptable alternative.
