Re: DB Slow, v$session_wait shoeing SQL*Net message from client

Simon, what is your CPU consumption? Are CPUs executing oracle processes (top) or sitting idle? If CPUs are executing oracle processes, you may have a problem with parsing. If they're sitting idle and doing nothing, your client program(s) may be to blame or you may have a network problem. Have you tried pinging the database server from a client PC? What kind of network do you have and what are the response times?
