Programming considerations for applications

BMC AMI Fast Path Indexer for IMS lets you perform complete and partial key searches.

This section discusses the following topics:

  • complete searches
  • partial searches
  • searches using a PCB that does not include the PROCSEQ keyword (primary sequence processing method)
  • searches using a PCB that includes the PROCSEQ keyword (alternate sequence processing method)
  • searches using a PCB with a secondary index
Warning

Note

BMC AMI Fast Path Indexer for IMS tries to keep calls to the primary DEDB and associated indexes to a minimum by restricting the use of non-keyed search fields. All field names that you include in an SSA must be the same as the XDFLD name or the sequence field name. If you use any other field name, IMS issues an AK status code.

The following figure shows a primary DEDB (DIVSSD), and Course information--SHISAM index or HISAM index (DIVSI4) shows a SHISAM or HISAM index (DIVSI4). The Student segment is the target segment and source segment.
