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.
How can use "renice" with RAC?
that is a good thing: we can use to apply on RAC.
ps –elf | grep lms
renice -20 –p pid1, pid2, pid3
ps –elf | grep ocssd
renice -20 –p pid
