Home -> Community -> Mailing Lists -> Oracle-L -> RE: Row level security and latch waits
Row level security and latch waitsI've developped 3 functions for
fined-grain access control and the users have tested them.
There are only 3-4 users in the acceptance env. and I did not noticed
anything.
What version are you running and how many users ? We're on 8172
Someday it will go in production here...

Subject: Row level security and latch waits
hi all,
in the latest code release, a group implemented RLS and since then spotlight is constantly flagging 'latch waits' in the system. Yesterday the latch waits were upwards of 90%.
Most active sessions seem to run the policy function defined as part of RLS. The worst part was all this wait was only on one node, the other node was healthy.
While we are trying to capture more information, anything else that we can do? Any ideas? TIA
Raj
