Overview

This Snap is used to acknowledge the Java Message Service (JMS) messages read by a JMS consumer used in the upstream Snap. This Snap should always be used in conjunction with JMS Consumer Snap in a Pipeline. The JMS Consumer Snap should have the Acknowledgement mode set to CLIENT_ACKNOWLEDGE and Processing mode set to Synchronous.

Acknowledgment Modes:

Client Acknowledge: When a message is read, the client acknowledges the message.
Auto Acknowledge: The messages are acknowledged automatically (by user) after the message is read.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

Stop Pipeline Execution: Stops the current pipeline execution when the Snap encounters an error.
Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the records.
Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Snap Settings

Field

Field Type

Description

Label

Default Value: JMS Acknowledge
Example: JMS Acknowledge

String

Specify a unique name for the Snap.

Recover message

Default Value: Deselected

Checkbox

Select this option to explicitly place a message back in the JMS queue to recover messages.

If the Snap fails to read the JMS messages for processing, you can recover those messages by selecting the Recover message checkbox so that the Snap can read the messages additional times for further processing.

Snap Execution

Default Value: Validate & Execute
Example: Execute only

Dropdown list

Select one of the three modes in which the Snap executes. Available options are:

Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.
Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
Disabled: Disables the Snap and all Snaps that are downstream from it.

Example

A Pipeline for JMS Acknowledge may look something like this:

Configure a Mapper Snap to join upstream Snaps to JMS Acknowledge:

The sample output of the JMS Acknowledge Snap may look like this:
