Connecting to Database
To run a database, you need to log into the database first. In the host navigation tree, right-click a database and select [Login Database] or double-click the database.
Enter a user name and password in the [Login Database] window. The default user name is dba; no password is required. If you want to store password at local machine, you can check the [Save Password] in order to log in this database by double-clicking this database node.

After user authorization is verified in the database login process, a tree corresponding to the user's authorization is displayed. To start the database, right-click the database in the left navigation tree and then sent [Start Database]. While the database is running, you can add a user or change the current password by right-clicking the [Users] node.
In the CUBRID Manager is not normally running, the following error message will be displayed: Cannot connect to a server. Please check the configuration environment of the CUBRID Manager server and other connection. In this case, you solve the problem by checking the following:
- Check whether the CUBRID Manager server is running.
- Open the configuration file of the CUBRID Manager server, and make sure that the value of the cm_port parameter is identical to the registered connection port. See Configuration the CUBRID Manager Server.
- If a firewall is installed on the system where the Manager client is running, allow all connection ports to be accessed to the Manager client connection (cm_port, cm_port+1). For example, if cm_port is 8001, the port 8002 must also be open.
- When the same operation is already being executed by the server, the message "Cannot execute the current operation because the previous operation is already running." is displayed. Then, retry the operation.
- When connecting Broker and a database in the CUBRID Manager client, the IP network between Broker and a database may be seperated. In that case, you must configure different addresses for the database and Broker in the Connection Information of the Database Property. To change connection information, right-click in the navigation tree and then select [Properties].
