Database Manager
The Database Manager has a client/server architecture. The DBM Server is responsible for the
functions, and the user uses the client to access the tool.
Database Manager clients can be used for remote connections. This means that the client and the
DBM Server can be installed on different hosts. However, the DBM Server must always be installed on
the same host as the database instance that you want to access with the Database Manager.
The Database Manager is a database tool for managing MAX DB databases. You can use it to
create, control, monitor, backup, and if necessary restore database instances on the local host or on
remote hosts.
The Database Manager consists of a server part and a client part. The following clients are available.
They provide similar functions, depending on your operating system and requirements:
 Database Manager GUI—Windows only
 Command-line oriented Database Manager CLI
 Web-based Web DBM
At the requests of the client (Database Manager GUI or Database Manager CLI), the X server starts the
DBM server. After a connection has been successfully created, an additional thread or an additional
child process is started in the X server process to transport the data packets over the network.
