Platform Load Tests Suite (plt)

Platform Load Tests Suite

The plt package contains the Platform Load Tests Suite that exercises a computer system under a heavy load. The suite is executed using plt(1Mcert), an interactive shell script.

Previous versions of this suite were called hcptest on OpenServer 5 and loadtests on UnixWare 7 systems.

For current information about the entire UnixWare/OpenServer Hardware Development Kit (HDK) release, see the HDK Release Notes.

Known limitations

Note the following limitations for this release:

  • The test suites automatically run the pltanalyze command when they complete to produce a summary report. Spurious failures may be reported if some tests have not yet written their final results to the log. Rerun pltanalyze manually after the test run finishes if the initial run reports failures.
