Activities

If there are multiple installations of the database software on your computer, you can use the database_name and dependent_path parameters to control which version of the Database Manager is started.

To create a new database with the newest software installation or display information about the existing databases and software versions, do not enter either database_name or dependent_path.

The system starts the Database Manager of the software installation that has the highest version number.
To manage a particular database, enter database_name, but not dependent_path.
The system then starts the version of the Database Manager belonging to the database specified.
To create a database of a particular software version, enter dependent_path but not database_name.
The system then starts the Database Manager of the software installation specified.

Example

To connect to DEMODB database on the local computer via the DBM server as database system administrator DBADMIN with password SECRET, generate a session object as follows:

Syntax Syntax

session = sdb.dbm.DBM ('', 'DEMODB', '', 'DBADMIN,SECRET')

End of the code.

To connect to the Database Manager of the latest software installation on the local computer, generate a session object as follows:

Syntax Syntax

```
session = sdb.dbm.DBM ('', '')
```

End of the code.

To connect to the remote computer PARMA and select the Database Manager from the software installation /usr/local/sdb/7600, generate a session object as follows:

Syntax Syntax

session = sdb.dbm.DBM ('PARMA', '', '/usr/local/sdb/7500')

End of the code.
