Tanel Poder has a great write up on it at http://blog.tanelpoder.com/2008/02/10/sqlnet-message-to-client-vs-sqlnet-more-data-to-client/ If orasrp is calling "SQL*Net message to client" an idle event it makes me wonder if they are getting it confused with "SQL*Net message from client" which can rolls up time that can be idle, network or work (as in application processing time) orasrp looks cool. I'll have to check it out! I'd heard about a 10046 analyzer from Russia but hadn't tracked it down. This orasrp must be it.
