PLB_USLEEPCOUNT Keyword

PLBLinux Only

PLB_USLEEPCOUNT={count}

This keyword adjusts the ratio of file unlock operations executed before a usleep function is executed in a FILEPI unlock action. This means that a usleep function is executed for every {nnnn} OS unlock operations. This keyword allows adjustment of the OS performance for FILEPI processing depending on the kind of application being used.

If the {nnnn} value is set to zero, no OS usleep operations are executed for a FILEPI unlock action. By setting the {nnnn} value to a low non-zero value can help to allow multiple user applications to access a file under a FILEPI in a balanced/equal manner. However, on some Linux OS systems the {nnnn} value may need to be set to a higher value or zero when a batch or single user application is being executed.
