Something for the internals
folks.....
Last
week we had a situation where the production system froze and we had to reboot
to
get
everything working again. Working with Oracle Support, we determained that
we had
encountered bug 2230693. The workaround was to
set the event listed above.
Sence
then I have noticed a significant increase in library cache miss rates
rates (5%-10%).
The
event doc indicates that level 2 on 10235 "Do 1 AND fill memory with junk on
alloc / free".
Does
this indicate that the library cache also backfills the hash area with junk
leading to the
miss
rate performace I am seeing, or should I be looking
elsewhere?
TIA,
John P Weatherman |
