The databases.txt file that has information on servers to be connected by a broker and their order is located in the $CUBRID_DATABASES (if not specified, $CUBRID/databases) directory; the information can be configured by using db_hosts. You can specify multiple nodes by using a colon (:).
The following example shows how to configure databases.txt.
#db-name vol-path db-host log-path lob-base-path
testdb /home/cubrid/DB/testdb nodeA:nodeB /home/cubrid/DB/testdb/log file:/home/cubrid/DB/testdb/lob
