Transaction I/O Waits Analysis workspace

The Transaction I/O Waits Analysis workspace is accessed as a link from the Transaction Timings workspace. This information is derived from two attributes groups: The Transaction I/O Waits attribute group and the Transaction I/O Other Waits attribute group; it allows you to examine in more detail the causes for a long wait by a particular task.

The predefined Transaction I/O Waits Analysis workspace contains the following views:

  • The I/O Waits Distribution pie chart displays the I/O waits for the following resources: temporary storage, transient data, files, journals, terminals, interregion (MRO), LU 6.1 and 6.2, FEPI, RLS files, shared temporary storage, and socket I/O.
  • The Other Waits Distribution pie chart displays waits for Re-dispatch, First dispatch, Local ENQ delays, local manager dispatch, WAIT EXTERNAL, WAIT CICS®, Interval Control elements, dispatchable, Global ENQ, RRMS/z/OS waits, CICS MAXOPEN, and JVM suspend time.
  • The I/O Waits Details for transaction tranid table displays the I/O wait times for temporary storage, transient data, files, journals, terminals, interregion (MRO), LU 6.1 and 6.2, FEPI, RLS files, shared temporary storage, and socket I/O.
  • The Other Waits Details table view displays the wait times for Re-Dispatch, 1st Dispatch Delay, Local ENQ Delay, Lock Manager Delay, WAIT EXTERNAL Time, WAITCICS and WAIT EVENT, Interval Control Delay, Dispatchable Wait Time, Global ENQ Delay, RRMS/z/OS, CICS MAXOPENTCBS Delay and JVM Suspend.
