renice Linux command

renice [priority] [options] [target]

Perhaps we need to control the scheduling priority of running processes. we can apply to a process, process group or user.

The range of allowable niceness values is -20 to +19:

A higher niceness value means that the process will run at a lower priority. A privileged user may set a negative priority (-20), to speed up processes.

that is a good thing: we can use to apply on RAC.

Example:

ps –elf | grep lms

renice -20 –p pid1, pid2, pid3

ps –elf | grep ocssd

renice -20 –p pid
