The databases.txt file that has information on servers to be connected by a broker and their order is located in the $CUBRID_DATABASES directory; the information can be configured by using db_hosts. You can specify multiple nodes by using a colon (:).
The following is an example of configuring databases.txt:
#db-name vol-path db-host log-path
tdb01 /home/cubrid/DB/tdb01 masterdb.cub:slavedb.cub /home/cubrid/DB/tdb01/log
tdb02 /home/cubrid/DB/tdb02 masterdb.cub:slavedb.cub /home/cubrid/DB/tdb02/log
