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.
