Applying Attributes to All Instances

When you edit the session properties, you can apply source, target, and transformation settings to all instances of the same type in the session. You can also apply settings to all partitions in a pipeline. You can apply reader or writer settings, connection settings, and properties settings.

For example, you might need to change a relational connection from a test to a production database for all the target instances in a session. On the Mapping tab, you can change the connection value for one target in a session and apply the connection to the other relational target objects.

The following table shows the options you can use to apply attributes to objects in a session. You can apply different options depending on whether the setting is a reader or writer, connection, or an object property.

Description

Applies a reader or writer type to all instances of the same object type in the session. For example, you can apply a relational reader type to all the other readers in the session.

Applies a reader or writer type to all the partitions in a pipeline.

For example, if you have four partitions, you can change the writer type in one partition for a target instance. Use this option to apply the change to the other three partitions.

Applies the same type of connection to all instances. Connection types are relational, FTP, queue, application, or external loader.

Apply a connection value to all instances or partitions. The connection value defines a specific connection that you can view in the connection browser. You can apply a connection value that is valid for the existing connection type.

Apply only the connection attribute values to all instances or partitions. Each type of connection has different attributes. You can apply connection attributes separately from connection values.

Apply the connection value and its connection attributes to all the other instances that have the same connection type. This option combines the connection option and the connection attribute option.

Applies the connection value and its attributes to all the other instances even if they do not have the same connection type. This option is similar to Apply Connection Data, but it lets you change the connection type.
