Re: Row level security and latch waits

RLS doesn't use bind variables? How then does Oracle treat the Application Context variables that you include in the predicates generated by the Security Policy functions? If those aren't bind variables then I guess I don't know what bind variables are.

Please refer me to the documentation on which your assertion is based.

Thanks.

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
