The production oracle instance is consuming all CPU !
How can this be tuned on OS/390.
In the database we see that started worker tasks (heavy I/O consuming SQL) are using all the CPU and inactive worker tasks are not activated, dispatched.
This results in bad performance of the oracle applications environment. HELP

If this is an application problem, join V$SESSION and V$SESSTAT on SID where STATISTIC# = 12. Look at the VALUE, LAST_CALL_ET, OSUSER, USER_NAME, etc. for all active STATUS.
