Hi Riccardo ,
The default replication will replicate all databases as there are no filters defined in the my.cnf
The caveat could be the time the otk database was created before or after you setup the original replication.
So verify if the otk database exist on bot MySQL nodes.
You can run "show databases;" on both nodes.
If te otk database does not exist you can run the create_slave.sh script to setup the initial database
/opt//SecureSpan/Appliance/bin/create_slave.sh
It will ask which database to replicate specify the otk database.
Secondly you have specify the failover on the OTK jdbc connection .
Change the url to look like
jdbc:mysql://MYSQLNODE1,MYSQLNODE2:3306/otk_db?failOverReadOnly=false&autoReconnect=true&connectTimeout=1
Regards
Dirk
