Measure Support for Open System Services (OSS)
Because multiple measurements can run concurrently, you can collect data with your
custom tools at the same time you are collecting data using MEASCOM.
The user-defined counters give you a structure to further customize your own products.
You can use these counters to measure application events and write the collected data
to data files generated by Measure. Selected, continuously monitored events could
form the basis of trend analyses for capacity planning or for better system performance
management.
Measure Support for Open System Services
(OSS)
The Open System Services (OSS) product provides a UNIX-like, standards-based
programming and interactive environment on NonStop servers. The OSS run-time
environment is present on G-series RVUs and includes the POSIX 1003.1 application
programming interfaces (APIs) and the POSIX 1003.2 utilities.
Measure G09 and later PVUs provide an integrated view of the OSS and Guardian
environments. The OSS Measure enhancements assist in the analysis and tuning of
OSS-based applications by supporting the capture, display, and use of OSS file
pathnames in measurement configurations and reports. OSS file pathname support
accounts for differences in command and programmatic interfaces, entity counters,
identifiers, callable interfaces, error messages, and warning messages. For details,
see the Measure Reference Manual.
Measure Support for ANSI SQL Names
Measure G11 and later PVUs provide ANSI SQL names in various measurement
reports and output. This lets an SQL/MX user see the SQL logical names instead of
seeing only the underlying system-generated Guardian file name.
For details, see the Measure Reference Manual.
Measure Support for Dynamic-Link Libraries
(DLLs)
Measure G12 and later PVUs support measurement of DLLs. For details, see the
Measure Reference Manual.
Measure Processes and Files
Most Measure processes and files that make up the Measure software are stored in
the subvolume $SYSTEM.SYS
