It includes instructions on the following: database management tasks (creating and deleting databases, adding volume, etc.), migration tasks (moving database to a different location or making changes so that it fits the system’s version), and making back-ups and rollbacks of the database in case of failures. See coradb Utilities.
It includes instructions on the system configuration. See System Parameters.
It includes how to use SystemTap, which can monitors and traces the operating processes dynamically. See SystemTap.
It includes instructions on troubleshooting. See Troubleshooting.

The coradb utilities provide features that can be used to comprehensively manage the CoraDB service. The CoraDB utilities are divided into the service management utility, which is used to manage the CoraDB service process, and the database management utility, which is used to manage the database.

Note

If you want to control the service by using coradb utility on Windows Vista or later, it is recommended that you run the command prompt with an administrator account. If you use coradb utility without an administrator account, the result message is not displayed even though you can run it through the User Account Control (UAC) dialog.

To run the command prompt on Windows Vista or later with an administrator account, right-click [Start] > [All Programs] > [Accessories] > [Command Prompt] and select [Run as Administrator]. In the dialog verifying authorization, click [Yes], and then the command prompt is run as an administrator account.
