HP Performance and Coverage Analyzer for OpenVMS
VAX Systems
The HP Performance and Coverage Analyzer (PCA) for
OpenVMS VAX Systems helps users pinpoint execution
bottlenecks in application programs. PCA can also iden-
tify which parts of an application are not executed by a
given set of test data. PCA has two components: the
Collector, which gathers performance or test coverage
data on the running user program; and the Analyzer,
which later processes and displays the collected data.
The Analyzer graphically presents information in four
types of charts: histograms, tables, annotated source
listings, and call trees.
PCA does not analyze operating system performance
or aid in hardware resource planning.
PCA can gather and report on the following types of
performance data:
• Call stacks
• CPU sampling data
• Event markers
• PC sampling data
• Page fault data
• System services data
• Input/Output data
• Exact execution counts
• Test coverage data
• Ada tasking data
Additional PCA features include the following:
• Traversing commands to sift through performance
data
• Screen mode to display different types of data in sep-
arate windows
• Multiple data kinds allowing the display of different
categories of performance data in the same his-
togram or table
• Acceptable noncoverage indicating portions of code
that are acceptably noncovered to the Analyzer
• Filtering to analyze only a subset of data
PCA works in concert with LSE and the Digital Test Man-
ager. From the character-cell version of PCA, users can
communicate with LSE and can examine source code.
When used with the Digital Test Manager, PCA can eval-
uate the code coverage of a user’s test system.
PCA provides a command-line interface and the
DECwindows Motif for OpenVMS VAX interface.
PCA is a component of the HP DECset for OpenVMS
VAX Systems product and is also available separately.

HP Code Management System for OpenVMS VAX
Systems
The HP Code Management System (CMS) for OpenVMS
VAX Systems provides an efficient method for storing
project files and tracking all changes to those files.
Code management is especially important to projects
that have long life spans or several versions of the soft-
ware.
CMS stores any kind of RMS file, including: documents,
plans, specifications, status reports, source code files,
object files, executable images, sixel files, and other
records, and keeps these files in project libraries. CMS
also stores history information. As a project evolves,
CMS tracks changes to the library by storing only the
changes made to a file. Not only does this reduce the
amount of disk space used for storing multiple versions
of files, but it also allows CMS to reconstruct any previ-
ous version of a file and to identify the changes made
between any two versions. In addition to storing suc-
cessive changes, CMS maintains a record of who is
currently working on a library element and a historical
record of library access.
With CMS, users can:
• Support multiple project libraries.
• Retrieve previous generations (versions).
• Delete generations.
• Obtain a report of file modi fications, including when,
why, and by whom the modification was made.
• Determine the origin of each line of a file, either as
an annotated listing or as comments in the file.
• Manage concurrent modifications.
• Merge separately developed modifications.
• Combine related files together as a class (group).
• Relate the generation of one element to the corre-
sponding generations of other elements for purposes
of freezing baselines or releases and for organizing
ongoing development.
