Hi, I'm preparing 2 servers with shared MySQL database. I'm not sure if the doc are outdated... are the following 3 settings required in switch.conf.xml: <param name="core-db-dsn" value="odbc://freeswitch:fs:password"/> <param name="core-recovery-db-dsn" value="odbc://freeswitch:fs:password"/> <param name="odbc-dsn" value="odbc://freeswitch:fs:password"/> Or is it enough only with "core-db-dsn" ? Should any of them go in the profile xml rather than the switch.conf.xml? What is the difference between "core-db-dsn" and "odbc-dsn" parameters? (in case "odbc-dsn" is still required) The idea is to run "sofia recover" on second node on the event of a failure on the first node, and to continue with call that are in progress. Thanks. Joel.
