implement sql92_security parameter
In running queries to see what I will affect by turning this parameter on, I see that there are some system items that have insert and update but not select on some tables. My assumption is that these will no longer work as I don't see any role that grants them select, but I'm not sure this is correct.
For example: both CTXSYS and XDB have insert,update on DR$THS (dictionary table). I don't see any role that grants them select on this table so if I turn on this feature will these accounts no longer have insert/update?
