5.9 Performance Application Programming Interface (API)
The Performance Application Programming Interface (API) provides a
documented functional interface—the $GETRMI system service—that allows
performance software engineers to access a predefined list of performance data
items.
For more information about $GETRMI, refer to the OpenVMS System Services

5.10 POLYCENTER Software Installation Utility Enhancements
Table 5–1 shows the changes made to the product description language (PDL) for
the POLYCENTER Software Installation utility.
Table 5–1 PDL Changes
Statement Description
execute upgrade New statement.
execute postinstall Modified to execute on a reconfigure operation.
file
module
Refinements made to their conflict detection and
resolution algorithms. For example, when a file from
the kit contains the same non-zero generation number
as the same file already installed, the file from the
kit is selected to replace the file on disk. Previously,
in this tie situation, the file on disk was retained to
resolve the conflict.
bootstrap block
execute release
patch image
patch text
Obsolete. However, the utility will continue to process
these statements in a backward compatible manner to
support existing kits that might have used them.
Function Description
upgrade Enhanced to fully support version range checking.
The POLYCENTER Software Installation Utility Developer’s Guide has been
extensively revised for this release. Major improvements include:
• Updated descriptions for most PDL statements.
• A comprehensive presentation on using custom command procedures with
execute statements (added to the Advanced Topics chapter).
• New tables, diagrams, and examples.
5.11 New Process Dump Tools (Alpha)
OpenVMS Version 7.3 contains new tools for processing dump files. Note that
these new-style process dump and process dump analysis tools are not compatible
with the old-style process dumps. That is, if you have a problem you want to
analyze with the new tools, you must generate a new process dump using the
new process dump image.
The following sections describe the new tools.
