The Datasource defines a connection to an external database. You need to define at least one of these in order to push and pull data to and from external database systems.
It has a name and a driver class (which should match the kind of datasource you are connecting to, e.g. Oracle, MySQL, SQLServer etc.). Remember to set the enabled flag to make the datasource active. Most importantly, ensure you have configured at least one datasource instance.
Datasource Instances
A Datasource Instance defines connection details to a database. A number of instances can be defined to allow for several connections under a single Datasource. At least one Datasource Instance must be defined for each Datasource.
A datasource instance has a name, a URL, and a username and password used to connect to the external datasource. The URL should be in one of the following formats:
Platform | Connection String |
|---|---|
Oracle | jdbc:oracle:thin:@hostname:1521:phixflow |
| Oracle (> 12c with PDB containers) | jdbc:oracle:thin:@hostname:1521/phixflow |
Sql Server | jdbc:sqlserver://hostname\myservice;databaseName=phixflow |
MySQL | jdbc:mysql://hostname/phixflow |
Advanced Configuration
There are two flags on the details tab that determine what credential the datasource sends when connecting to the external source.
When the Anonymous Export Allowed flag is ticked, the datasource can be used by an exporter as part of the work done in executing a task e.g. when processing a scheduled task. In this mode, the datasource will use the configured anonymous username and password. If anonymous export is not allowed, the datasource cannot be used by an exporter during the execution of a task. The datasource can only use the logged in user's credentials (see Use user credentials below).
When the Use User Credentials on Export flag is ticked, the current logged in user's own PhixFlow username and password will be used to connect to the target database when an exporter is used interactively. Note that this means that the username/password must be set up on the target system by a Database Administrator.
This is an advanced (optional) setting. Use this field when connections to the target database might go "stale", e.g. if the target database disconnects long running connections. Setting this field causes PhixFlow to run 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 also database collectors for guidance on writing SQL queries in PhixFlow.
Datasource behaviour is also determined by these parameters set elsewhere in PhixFlow:
- Privilege 'Allow anonymous updates on datasources'. Only a user with this privilege can modify the 'Anonymous export allowed' flag on a datasource.
- System Configuration. parameter 'Allow anonymous export by default'. This causes the 'Anonymous export allowed' to be true by default on all new datasources.
Form Icons
The form provides the standard form icons as well as the following:
