The Performance and Coverage Analyzer for OpenVMS
(PCA) analyzes the run-time behavior of your user
application. PCA serves the following functions:
o It pinpoints execution bottlenecks in an application
program, and then lets you determine their causes.
o It analyzes test coverage by measuring which parts
of an application are or are not executed by a given
set of test data.

2 – Overview frame
PCA collects performance information on your
application and lets you view that information
to observe the runtime characteristics of your
application, such as:
o Where your application spends the most time
o What parts of your application are executed the most
o What parts of your application are compute-bound or
I/O-bound
o What areas of your application are, or are not,
executed by tests
o What the dynamic call relationships are among the
routines in your application
o Where page faults occur
o Where you use system services
With this information, PCA helps you pinpoint important
qualities of your application, such as the location
and nature of performance bottlenecks, or how effective
your test coverage is.
For more information on what PCA does and how to use
PCA, refer to:
o Overview topics in the online help
o The hardcopy manual, Guide to DIGITAL Performance
and Coverage Analyzer for OpenVMS Systems.

4 – Glossary frame
o Bottleneck
Specific areas of an application where the
performance needs to be improved.
o Chart
The pictorial representations of the data that are
presented during PCA analysis.
o Correlation Table
A chart that shows the relationship between several
kinds of data.
o Counting
Collection information about each andevery
occurrence of some event.
o CPU Bound
Description of a process in which the time spent
executing code on a processor is greater than the
time spent performing I/O operations.
o Data Item
Pieces of information that are gathered by the PCA
Collector and presented by the PCA Analyzer.
o Elapsed Time
Time as measured by a clock or a watch. Elapsed time
accumulates regardless of the state of the process
being timed.
o Granularity
The amount of detail presented in a chart. An
example for increasing granularity is charting a
set of modules, then the routines in a particular
module, then the source lines in particular routine.
o Histogram
A chart that graphically presents the frequency of
data.
o I/O Bound
An I/O bound process is one in which the time spent
is performing I/O operations is far greater than the
time spent executing code.
o Line
A generic term for an individual line of source code
o Module
A generic term for a collection of routines. See
Routine.
o Process Time
Time during which a process is actually running.
Another name for this is CPU process being
timestime. Process time increments only when the
timed is actually running on a CPU. No time is
accumulated when the process is not running.
o Program Element
A generic term for a component of an application,
such as a module, routine, line, or statement.
o Routine
A generic term for a function, procedure, routine,
or subroutine, depending on the programming language
you are using. See Module.
o Query
A question or inquiry made by the user. For example,
"How many times were all of the routines in this
application called?"
o Sampling
The collection os a subset of possible events that
allow statistical prediction of the outcome of
collecting information about the entire set.
o Sampling Rate
The time between sampling timer ticks.
o Selection
An item that the user has indicated interest in,
generally by clicking on the item.
o Sort Order
The order in which a chart is sorted; for
example, from the largest to the smallest value,
alphabetically, or not at all.
o Table
A chart that presents values expresses by means
other than percentages.
o Viewpoint
The perspective from which you observe data. For
example, if you have collected information about
the system services used by your application, you
can look at this system services information from
the perspective of either where system services were
used or what those system services are.
o Zoom In
To change a chart to be of a finer granularity.
o Zoom Out
To change a chart to be of broader granularity.
