EspSubscriber ConfigurationLocate this document in the navigation structure

The ESP Subscriber module obtains data from the SAP Event Stream Processor project and passes it along to a transporter or formatter module. Specify values for the EspSubscriber module in the adapter configuration file. Specify this module for an output adapter only.

XML Element Description
ProjectName

Type: string

(Required if running adapter in standalone mode; optional if running in managed mode) Specifies the unique project tag of the ESP project to which the adapter is connected. For example, StreamingProject2.

This is the same project tag that you specify later in the adapter configuration file in the Name element within the Event Stream Processor (EspProjects) element.

If you are starting the adapter with the ESP project to which it is attached (running the adapter in managed mode), you do not need to set this element as the adapter automatically detects the project name.

StreamName

Type: string

(Required if running adapter in standalone mode; optional if running in managed mode) Name of te stream from which the adapter subscribes to data.

If you are starting the adapter with the ESP project to which it is attached (running the adapter in managed mode), you do not need to set this element as the adapter automatically detects the stream name.

EnableGDMode

Type: boolean

(Advanced) Specifies whether the adapter runs in guaranteed delivery (GD) mode. GD ensures that data continues to be processed in the case that the ESP Server fails, or the destination (third-party server) fails or does not respond for a long time. See Guaranteed Delivery in the SAP Event Stream Processor: Developer Guide for details on enabling GD for your project.

The default value is false.

EnableGDCache

Type: boolean

(Advanced) If set to true, only rows that can be recovered (that is, checkpointed) by the ESP Server on restart are sent to the end source. Other rows are cached internally by the adapter.

GDSubscriberName

Type: string

(Advanced) If the adapter is running in GD mode (the EnableGDMode property is set to true), specify a unique name to identify the GD subscription client. If this value is empty when running in GD mode, the adapter logs an error and shuts down.
