i have oracle 12g installed on Amazon linux ,
after i stop working with it and no process do any request or sql querys .
I noticed i have 100% cpu utilization and allot of "somekind" of oracle process runnig
that looks like this when doing TOP :
31023 oracle 20 0 3271180 56688 53628 R 52.6 0.8 1:05.20 oracle_31023_orc
