Dear All,
I am having some confusion regarding OS(Redhat 7) swaping in respect to oracle database instance:
1. db buffer cache is the biggest chunk of memory region in SGA,which used for data block read from disk. When, buffer cache is full and for allocation of new data block,when old buffer getting aged out,Will this consider as swapping??
Or
2.In PGA, we allocate small memory region in compare to SGA.However, each Oracle process(which is also OS process) has their own PGA,when there is some interchange of data between PGA and temporary TBS,that will consider as swapping???
Or
3,Swapping is consider when OS related memory age out from memory and write in OS swap space??
Regards,
