Hello
Yesterday i got wait event when executed simple select from table.
This select was like:
SELECT emp_number from employer where subs_id = 111
I got one row, select is very fast.
In our Core Bank System we have package with function which returns such information. I tested this select on test DB, and nothing wrong. But when I executed such select and package on Production DB, DB Admin saw that 88 sessions waits when
my session release the resource. But what can happen, it was simple select?
I used PL/SQL developer to get information from table:
1) SELECT emp_number from employer where subs_id = 111
then
2) Package with this function
Another users used Oracle Forms screen to execute package.
So question, How simple select statement could stop all DB?
