Modifying external processes
You can free up system resources by modifying external processes.
Terminating processes
Terminate unnecessary system processes by taking these steps:
- If you do not bridge applications, enter xferdip_off to terminate the xferdip process.
- If a line printer is not being used with the system, enter the command /usr/lib/lpshut to turn off the lp scheduler. You may also rename the S80lp file from the /etc/rc2.d directory to s80lp . This action prevents the process from being executed during startup, but maintains the file on the system should the scheduler be needed in the future.
- Eliminate network processes, such as rwhod and routed, that are not required.
- Do not run sysmon in systems with insufficient memory.
Reducing and rescheduling processes
- Cut back on the use of demanding processes, or schedule them for a time when voice activity is low or non-existent. Demanding processes include running call data reports, reviewing sysmon, creating backups, administering speech, and so forth.
- If no processes can be eliminated, be sure that all the packages on your system are being used and are not occupying memory unnecessarily.
- Finally, if the nbufs parameter has been specified in the /vs/data/spchconfig file and a large number is specified, consider reducing nbufs. Reducing nbufs may increase the number of times that the hard disk is read for speech. However, the voice system is more tolerant of disk reading for speech than for paging.
