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.
