Thread cross-reference data

Use this topic as a reference to the format of the thread cross-reference type accounting record.

The interpretation of the data in the thread cross-reference (QWHCCV) field varies. This depends on what the data relates to:
  • CICS® connections (QWHCATYP=1) - see Table 1
  • IMS connections (QWHCATYP=3 or 4) - see Table 2
  • Batch connections (QWHCATYP=2 or 7) - this field consists of binary zeros
  • Others - no meaningful data
Table 1. Structure of the thread cross-reference for a CICS system
Offset: Dec Offset: Hex Type Length Description
48 30 Character 4 CICS thread number.
52 34 Character 4 CICS transaction name.
56 38 Integer 4 CICS task number.

Some entries contain blank characters. These apply to the task, rather than to a specific transaction.

Table 2. Structure of the thread cross-reference for an IMS system
Offset: Dec Offset: Hex Type Length Description
48 30 Character 4 IMS partition specification table (PST) region identifier.
52 34 Character 8 IMS program specification block (PSB) name.
