Truth is I don't know of any database server that has intergrated the feature of forwarding his logs to remote servers. Of course if forwarding to the local logging facility of windows i.e. was supported, you could then sent them to a syslogd. But about oracle, I am pretty sure the massive "redo log files" can not be handled by an external log facility. I think that mssql also does not support passing logs to external facility as it comes with it's own comprehensive auditing tools.
