"Server-side TAF" is a reference to storing the TAF configuration info in the server, and having the client pull it down at connect-time. Not well documented, but very interesting. Look out for surprising rules of precedence - the server configuration always over-rides the client tnsnames.ora! See also: http://www.ardentperf.com/2007/03/29/centralized-taf-configuration-in-10g-part-2/ I've configured TAF for automatic failover to a standby (along with dataguard broker automatic failover) -- but I haven't configured TAF for both RAC and DG in the same database. It would be cool to hear if someone else out there on the list has done this. :) -Jeremy On Fri, Jun 19, 2009 at 3:03 PM, Charles Schultz <sacrophyte@xxxxxxxxx>wrote: > For #2, I do see table > 95-3<http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/d_serv.htm#sthref5797>, > but I missed how it specified "server-side TAF".
