Write to operator (WTO) messages

Write to operator messages (WTO) are generated by IMS Index Builder, DFSPREC0, the Build Index function of FPA, IMS High Performance Image Copy, IMS Library Integrity Utilities, IMS High Performance Pointer Checker, and DEDB Pointer Checker.

For the RPTTYPE=SEP and RPTTYPE=APP options, write to operator messages generated by IMS Index Builder, DFSPREC0, IMS High Performance Image Copy, IMS Library Integrity Utilities, IMS High Performance Pointer Checker, and DEDB Pointer Checker in the various address spaces are collected by the RAUX control task in the MAS.

• If the RPTTYPE=SEP option is specified, then all messages from the integrated auxiliary utilities are written to the FRXWTO DD in the MAS.
• If the RPTTYPE=APP option is specified, they are written to the REPORT DD in the MAS.
• If the RPTTYPE=SAS option is specified, then all WTO messages from the integrated auxiliary utilities are simply left on the job log in the subordinate address space (SAS) in which they were generated.

  RPTTYPE=SAS reduces the overall processing time and I/O for IMS Database Recovery Facility.

• In all cases, the WTO messages are separated by DD Name and DD/Area Name. Additionally, the address space in which they originated is listed.
