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.

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.
