Each datasource must have at least one datasource instance. You can add several instances if you want to configure different settings. For example you may want to connect to the same database using a different username and password for different scheduled tasks.
In the properties for collectors and exporters, you can optionally specify the datasource instance using the Advanced → Datasource Instance Expression.
The datasource properties are affected by:

For a datasource, you must:
- Enter a Name.
- Select a Driver class.
- Add at least one datasource instance.
- Tick the Enabled check box when it is ready to use.
We recommend you tick Protect during import to prevent this datasource being updated or deleted during import.

When an exporter uses this datasource to connect to a database, by default PhixFlow will use the PhixFlow username and password. Use this option when the PhixFlow username and password should not or cannot be used, for example in a scheduled task plan. The target database must permit anonymous updates.

to preserve this datasource during import. This prevents the datasource being updated or deleted. Insert excerpt _check_box_ticked _check_box_ticked nopanel true
Exception: The datasource will be deleted when its parent application is deleted by the import. This prevents orphaned datasources persisting in PhixFlow.
Select the driver class for the type of database to which the datasource connects.
| Tip |
|---|
The drop-down list may contain driver classes that are deprecated and do not have the necessary database drivers; see Driver Classes. |
Datasource Instances

The grid contains a list of datasource instances that belong to this datasource. Double-click on a row to open the datasource instance properties.

Only use these options if you know about database connections and SQL queries. For help with these options, contact support@phixflow.com.
| Field | Description |

Check Query | Use this field when connections to the target database might go stale. This can happen if the target database disconnects long-running connections. Enter a database query that will return a row from the database. PhixFlow runs the query against the database just before each use of a pooled connection. If the query does not return a row, the connection is discarded and a new connection is created. To avoid any performance impact, the query should execute quickly. See the Query String section of the Database Collector page for information about writing SQL queries in PhixFlow. |
| Datasource Profile | Use this field when the target database has additional requirements not covered by the datasource and datasource instance properties. Enter the path to an external datasource connection profile. PhixFlow will use the configuration information in the profile to connect to the target database. |
| Description | Optionally enter a information about the advanced configuration. |
