How does CPU_PER_SESSION work? Does it look at CPU time the session used executing a SQL and adds up every execution and when the value of CPU_per_session is reached the session errors out? That is what it sounds like. How does it work when there is more than one processor server?
Thank you.

Hi,
CPU_PER_SESSION keeps track of the accumulated CPU time (processing time in hundredth of seconds) whatever the CPU the session is executing on.
Here is an example:
SQL> ALTER SYSTEM SET RESOURCE_LIMIT = true SCOPE=MEMORY;
System altered.
SQL> CREATE PROFILE save_cpu_time LIMIT cpu_per_session 1;
Profile created.
SQL> ALTER USER SCOTT PROFILE save_cpu_time;
User altered.
SQL> CONNECT scott/tiger
Connected.
SQL> CREATE TABLE bigemp AS SELECT * FROM emp;
Table created.
SQL> INSERT INTO bigemp SELECT * FROM bigemp;
INSERT INTO bigemp SELECT * FROM bigemp
*
ERROR at line 1:
ORA-02392: exceeded session limit on CPU usage, you are being logged off
Best regards.
Frank
