hi list, We are running Oracle 9iR2 on Linux ES4. there are certain oracle process which is consuming almost 100% of the cpu. I tried finding if there is any latch issue but could not find any specific problem though I am not very good DBA but I tried all the possibilities I could. Could anyone please let me how to figure this problem out and resolve it?? System config : 4 CPU with 1GB RAM TIA Bala
