I'm not sure what you are meaning by that. Or if you are trying to modify the current database name, like @Randy Calvert said, follow this steps.
1. Connect in your FTP.
2. Go to File Manager » public_html » Where your IPS Suite is Installed and than find conf_global.php
3. Right click on conf_global.php than press edit. And there you should have all the database informations you need.
After you opened it, It should look like this.
<?php
$INFO = array (
'sql_host' => 'localhost',
'sql_database' => 'database_name',
'sql_user' => 'database_user',
'sql_pass' => 'database_password',
'sql_port' => 1111,
'sql_socket' => '/var/lib/mysql/mysql.sock',
'sql_tbl_prefix' => '',
'sql_utf8mb4' => true,
'board_start' => 69696969,
'installed' => true,
'base_url' => 'https://yourcommunityname.com/',
'guest_group' => 1,
'member_group' => 1,
'admin_group' => 1,
);
But if it's mysql related to linux. Here is a documentation about MySQL. https://dev.mysql.com/doc/
