I don't want to use stand-by server. I am aware of it and what it does. Let assume I have oracle rdbms behind obsd firewall (working as a bridge) and it works ok. Now obsd is a single point of failure (SPOF) and if it crashes/hangs (due to e.g. hardware failure) nobody can access oracle. If I setup second obsd fw in a pair with the first (using carp + pfsync) the obsd is not a SPOF but I am not sure if such configuration influences sqlnet traffic somehow. przemol
