• This record generates a row in the DMH IMS PCB table of the data base, if it does not exist.
• The first six attribute fields must be specified:
  • psbName is the PSB name coded on the PSB macro NAME= parameter. If this differs from the file name in the PSB container, the file name specified in the PSB container is used.
  • pcbSequenceNumber is a consecutive integer beginning with one used to indicate the count of PCBs in the PSB file.
  • keyLength indicates the length, in bytes, of the concatenated key of the segments along the retrieval path.
  • pcbType identifies the type of PCB being defined. It must be one of the following:
    • DB
    • GSAM
    • TP
  • dbdName indicates the name of the DBD that defines the segments that are named in this PCB, otherwise zero.
  • processOptions identify the type of processing that can be performed on each segment. The codes in this field define what type of calls are allowed.
• The seventh attribute field is optional:
  • pcbName
