Tuning Virtual Processor Manager (VPM)

Oracle recommends that you use the vpm_xvcpus command to tune virtual processor.

When you enable CPU folding with only one CUP, your system may reboot and face performance problems.

1. Check if CPU folding is enabled:

   schedo -L| grep "vpm_xvcpus" |cut -d " " -f 17

   The above command returns 0 if CPU folding is enabled.
2. Set value of the vpm_xvcpus parameter to at least 2:

   schedo -o vpm_xvcpus=2
