An IBM senior analyst has recommended the following VMM parameter settings for Oracle RAC
\ninstallation:
\n.
\nminperm%=3 maxperm%=90 maxclient%=90, lru_file_repage=0<\/p>\n
It eliminates or reduces most paging issues since numperm has to drop below 3% before
\ncomputational pages would be selected.
