Dispatcher TCB Modes Report

Figure 61 shows the format of the Dispatcher TCB Modes report. This report is produced using the EXEC CICS® COLLECT STATISTICS DISPATCHER command. The statistics data is mapped by the DFHDSGDS DSECT. The field headings and contents are described in Table 185. In the Dispatcher TCB Modes report, some fields (for example, TCB Allocates) only apply to open TCB modes. The validity of these fields for each mode can only be determined once a TCB has been attached in that mode. Until the first TCB has been attached in that mode, the fields are marked 'N/A'. Once the first TCB has been attached in that mode, if it is not an open TCB mode, the field continues to be marked 'N/A'. If it is an open TCB mode, the field is given a value.

TCBs attached -- Current The total number of TCBs currently attached.

Source field: DSGTCBCA for each TCB mode

Total TCB CPU Time The total accumulated CPU time taken for the active TCBs.

TCB Mode The name of the TCB mode that the statistics refer to. The names of the TCB modes are 'QR', 'RO', 'CO', 'SZ', 'RP', 'FO', 'SL', 'SO', Start of changeSP,End of change 'D2', 'JM', 'S8', 'L8', Start of change 'L9', End of change 'J8', 'J9', Start of change 'X8', and 'X9'.End of change

Source field: DSGTCBNM

Open Indicates whether this TCB mode is an open TCB mode, not an open TCB mode, or unknown. Unknown means that this TCB mode has not been activated; the first request for a TCB in a particular mode will cause the mode to be activated.

Source field: DSGTCBMD

TCB Pool The name of the TCB pool in which this TCB mode is defined: JVM, OPEN, Start of change SSL,End of change Start of change XP,End of change or N/A.

Source field: DSGTCBMP

TCBs Attached - Current The current number of TCBs attached in this mode.

Source field: DSGTCBCA

TCBs Attached - Peak The peak number of TCBs attached in this mode.

Source field: DSGTCBPA

TCBs In Use - Current The current number of TCBs in use in this mode.

Source field: DSGCMUSD
TCBs In Use - Peak The peak number of TCBs in use in this mode.

Source field: DSGPMUSD

TCB Allocates The number of times a TCB from this TCB mode was allocated to a task (that is, CICS assigned the TCB for the use of a particular task). TCB allocates only apply to open TCB modes. 'N/A' means either that this is not an open TCB mode, or that no TCBs have yet been created in this mode.

Source field: DSGTCBAL

TCBs Attached - Current The total number of TCBs currently attached for all modes.
