Hi all,
Struggling w/Oracle Support over a possible BUG on 8.1.6.0.0 and Solaris 2.8 where the shared pool can become fragmented by statements which have "AND-EQUALS" access. This has the effect of eventually hitting ORA-4031s.
Can someone explain what an "AND-EQUALS" access would be? I assume it would be a path chosen by the optimizer, but I can't find any mention of it on Tahiti. Perhaps provide an example?
TIA!
