Disk Agents
This section describes the Disk collection and forwarding agents. These agents are available in batch and real-time workflow configurations.
The Disk agents collect and forward batches of files on local file systems and are available in batch and real-time workflow configurations.
The configuration of the Disk agents is different in real-time workflows compared to batch workflows since the former do not have built-in batch boundaries. Batch workflows also provide built-in support for transaction safety and enable additional features in the Disk agents that are not available in real-time workflows.
However, you can include the collection and forwarding agents that are based on batch agents in real-time workflows. This allows you to use various file-oriented protocols, and access your batch data directly from a real-time workflow.
The collection and forwarding agents that are available are:
Disk
FTP
SCP
SFTP
When you have selected to create a real-time workflow, you can select these agents from the lists of collection and forwarding agents in the agent pane.
A real-time workflow with a batch-based agent:
Can process several UDRs simultaneously, but the order of UDR processing is not guaranteed.
The Begin and End Batch are signaled to the workflow.
Decoder, error management, and scheduling are defined as part of the collection agent configuration.
If the agent encounters an error that would cause a batch workflow to abort, instead behavior depends on how the agent is configured in the Execution tab.
For more information about the difference between batch and real-time workflows, see Workflow Types.
