Sqlquery to find out high CPU usage

Question

Hi,
I want to find out the queries which using high CPU in a RAC database. What is the best way to find it out.
Regards,
Koushik

Answer 1

I have executed the following query block enabling set event level 12.
begin
for i_rec in 1..4000
loop
TRD_TABLE_POPULATION;
end loop;
end;
The procedure contains deque and merge statement. Please find the output below of the trace output.

count = number of times OCI procedure was executed
cpu = cpu time in seconds executing
elapsed = elapsed time in seconds executing
disk = number of physical reads of buffers from disk
query = number of buffers gotten for consistent read
current = number of buffers gotten in current mode (usually for update)
rows = number of rows processed by the fetch or execute call
