Switch from an alternate database to the built-in database

You can switch to the built-in (default) CloudBees CD/RO database at any time. The following procedure shows how to switch to the built-in database from any CloudBees CD/RO-supported alternate database.

Using the built-in database is possible only if during the installation it was activated via the --installDatabase installer parameter or by the corresponding options in the GUI installer.

If you are using two different CloudBees CD/RO servers in a non-HA configuration, they cannot point to the same database.

If the built-in database service is disabled, enable and start it.

To do so, enter the following ecconfigure command:
```
ecconfigure --databaseEnableService=1▼
```
Point the CloudBees CD/RO server to use the built-in database.

You can use the UI or the ectool setDatabaseConfiguration command. If you did not change the default values for the password (changeme) and port (8900), enter the following:
```
ectool setDatabaseConfiguration --databaseType builtin --hostName localhost --userName root --databaseName eflow▼
```
If you have changed the default values (either during or after installation) for the password and port, enter:
```
ectool setDatabaseConfiguration --databaseType builtin --hostName localhost --userName root --password <password> --port <port_number> --databaseName eflow▼
```
