Calculated fields

In the examples that follow, a number of calculations are shown that can be performed using the transaction's total suspend (wait) time field and the individual suspend (wait) time fields.

Total I/O wait time

Total I/O wait time =
  • (Terminal I/O wait time +
  • Temporary Storage I/O wait time +
  • Shared Temporary Storage I/O wait time +
  • Transient Data I/O wait time +
  • Journal (MVS™ Logger) I/O wait time +
  • File I/O wait time +
  • RLS File I/O wait time +
  • Coupling Facility Data Table I/O wait time +
  • Inbound Socket I/O wait time +
  • Outbound Socket I/O wait time +
  • Inter-Region (MRO) I/O wait time +
  • LU 6.1 I/O wait time +
  • LU 6.2 I/O wait time +
  • FEPI I/O wait time +
  • IPCONN link wait time)

Total Other wait time

Total Other wait time =
  • (First Dispatch delay time +
  • CICS® MAXHPTCBS delay time +
  • CICS MAXJVMTCBS delay time +
  • CICS MAXOPENTCBS delay time +
  • Local ENQ delay time +
  • Global ENQ delay time +
  • Interval Control delay time +
  • Lock Manager (LM) delay time +
  • EXEC CICS WAIT EXTERNAL wait time +
  • EXEC CICS WAITCICS wait time +
  • Request Receiver wait time +
  • Request Processor wait time +
  • CICS MAXSSLTCBS delay time +
  • CICS MAXXPTCBS delay time +
  • CICS change-TCB mode delay time +
  • RRMS/MVS indoubt wait time +
  • 3270 bridge partner wait time +
  • Coupling Facility Data Table (CFDT) server syncpoint wait time +
  • CICS BTS Run Transaction synchronous wait time +
  • CICS BTS Syncpoint delay time +
  • RMI suspend time +
  • JVM suspend time +
  • TCB mismatch wait time +
  • MVS storage constraint wait time +
  • Dispatchable Waits wait time)
Note:
  1. The First Dispatch Delay field includes the MXT Delay and TRANCLASS delay fields.
  2. The RMI Suspend Time field includes:
    • DB2® READYQ wait time
    • DB2 connection wait time
    • DB2 wait time
    • IMS™ wait time
    • WebSphere® MQ GETWAIT wait time

    See RMI elapsed and suspend time for further information.

Unaccounted (Uncaptured) wait time

The unaccounted wait time is the amount of transaction suspend (wait) time that is not specifically measured in an individual wait time field.

Unaccounted wait time =
  • (Suspend time - (Total I/O wait time + Total Other wait time))
