i am trying to understand the user profile resource parameter CPU_PER_CALL. basically i know that this has something to do about the amount of CPU that a single SQL statement can be run.
i alter the profile and set the CPU_PER_CALL to 300 -- for 5 minutes
alter profile NYS_ADHOC_PROFILE_00 limit CPU_PER_CALL 300;
then i purposely run a query
select a.* from table_a a, table_b;
in less than 1 minute it throws an erorr:
ERROR at line 1:
ORA-02393: exceeded call limit on CPU usage
was that the default behavior because if i understand it correctly should have been reach 5 minutes before it throws the error. or was it that the optimizer already knows that the query will go beyond the 5 minutes and that is why it throws the error even before the 5 minutes?
