Dispatcher domain: TCB Mode statistics

These statistics can be accessed online using the EXEC CICS COLLECT STATISTICS DISPATCHER command, and are mapped by the DFHDSGDS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.

Two passes are made at the data, producing two TCB Mode statistics tables, as the statistics cannot all be fitted into a single table within the format of the report. The first table mainly contains the TCB event information, such as attaches, detaches and steals, for each mode. The second table has timing information, such as operating system wait time, waits, TCB dispatch and CPU times.

The following fields are mapped by the DSGTCBM DSECT within the DFHDSGDS DSECT. The DSGTCBM DSECT is repeated for each mode of TCB in CICS (DSGASIZE). For a list of modes of TCB, see Interpreting dispatcher statistics.
