Assuming UNIX variants...
I'm working on implementing the CIS guidelines for Oracle 10g in a database, and I'm a bit confused over one of them:-- http://www.freelists.org/webpage/oracle-l Received on Thu Oct 25 2007 - 02:08:32 CDT
6.02 Cache -- Cache must be emptied at shut down of Oracle.
"Information in caches may be accessed outside of Oracle and beyond the control of the security parameters."
First of all, they don't mention which caches need to be emptied at shutdown -- I'm assuming the buffer cache and the shared pool. Second, how could information in the cache be accessed after the instance is shut down? Does the data still exist in memory until overwritten? If so, then I guess someone with the right utility could read those memory addresses and the OS wouldn't prevent them because the addresses no longer belonged to a process?
