IMS Index Builder output files

IMS Index Builder has a main output file and, depending on the type of processing, up to three additional output files.

Main report file

File IIUPRINT is the main output file. It is formatted so as to be easily browsed on a 3278 type terminal.

In the file, every message starts with an ID in the form:

  IIUBnnnt

Where:

  • nnn is a 3-digit decimal number
  • t is a character that can be I for information, W for warning, or E for error

IMS Index Builder prints the following information in file IIUPRINT:

  • Processing options that you selected
  • Layout of the indexes to be built
  • Content of file DFSVSAMP when scan is used on the physical database and DFSVSAMP is not provided by you
  • The number of scanned segments that are in the prime database
  • The number of records for indexes that were successfully built
  • Diagnostic information for indexes that could not be built

Sort output file

The output from each sort is printed in the file that is specified by the IIUSOUT DD statement.

When sort problems are encountered, inspect the IIUSOUT data set.

Process events output file

File IIUSNAP is used to snap out time-sequenced Index Builder starting and stopping messages.

Under IMS Database Recovery Facility, IIUCAPT is the process events output file.
