The Transaction detail view shows
a transaction performance analysis summary for a specific transaction
over a time interval in a graphical format. Information is shown as
a timeline and number of pie charts and associated details.
For transaction performance conditions for a specified
instance of a transaction, you can use the Transaction performance
detail view. See Viewing performance history.
You
can access this view from transaction summary data in the Sheet view.
See Viewing performance history.
The
view title shows the transaction name.
The information line
shows the parameters that describe the time interval, the APPLID and
the transaction ID.
Transaction response time
This chart shows
the transaction response time divided into Average User Dispatch time,
Average Dispatch wait time, Average User CPU time, and Average Suspend
time.
For further details about the transaction response time,
view the information on the CICS Response time, User CPU time, and
Suspend time pie charts.
You can use the Transaction
response time twistie to show or hide this section.
Transaction Performance Summary at a glance
This
section shows a thumbnail of the available pie charts. Click on a
pie chart to view a full sized pie chart and its associated details.
On a full sized pie chart, click the pie segments to highlight the
corresponding component in the adjacent table.
By default, all
charts are available, but you can set CICS® PA plug-in preferences
to disable specific categories of analysis and restrict the associated
charts. If the analysis you require is not available, check the Categorization
enablement preferences. See CICS Performance Analyzer Preferences.
You

to show or hide this section.
The following
pie charts are available:
- CICS Response time
- This chart shows the transaction response time divided into User
Dispatch time and Suspend time.
- User Dispatch time is divided further into User CPU time with
an analysis of the CICS Dispatcher-managed
Task control Blocks (TCBs) that the transaction used.
- Suspend time also shows the Dispatch wait time that the transaction
incurred and the CICS TCB mode
when the wait occurred.
- User CPU time
- This chart shows an analysis of the CPU time and dispatch count
on the CICS Dispatcher-managed
TCBs that the transaction used. User CPU time analysis, including
CPU time on standard CPs, offload eligible CPU time, and CPU time
on specialty processors is also shown.
For more information about
these performance class fields, see Open TCB management in the CICS TS V5.2 product
documentation.
- Suspend time
- This chart shows the individual suspend time components separated
into wait type groups. Each suspend time component is shown with its
elapsed wait time and number of waits that were accumulated. Uncaptured
wait time is suspend time that CICS TS
does not capture with a wait time metric.
- CICS RMI usage
- This chart shows the Resource Manager Interface (RMI) usage analysis.
It shows elapsed time spent in, and the number of requests made to,
the CICS resource managers
(such as DB2® or WebSphere® MQ) that the transaction used.
- Storage usage
- This chart shows the GETMAIN requests and high-water mark values
for the different types of CICS storage
that the transaction used, broken down by CICS Dynamic Storage Area (DSA). This chart
represents the amount of storage used, not the amount of storage available.
- File Request activity
- This chart shows the number and type of file requests that the
transaction issued. A breakdown of the file-related I/O wait times
and their relationship with the total suspend time for the transaction
is also shown.
- Program Request activity
- This chart shows the number and type of program requests that
the transaction issued. A breakdown of the program load time is also
shown.
- Transient Data Request activity
- This chart shows the number and type of transient data requests
that the transaction issued. A breakdown of the wait times related
to transient data and their relationship with the total suspend time
for the transaction is also shown.

fields that are displayed, see
