Input Signature Properties for the Peek Service
When you configure the Peek service, the following properties are passed from the Peek Service tab in Designer to the input signature of the Peek service:
Property
Description
waitInterval
The time period that the service waits for a message to appear on the queue. Enter this value in milliseconds.
You set the value of this Integer in the Pipeline Editor, which overwrites the value set on the Peek Service tab.
Default: 60000
resetCursor
A String that contains the value of the resetCursor is set on the Peek Service tab.
Set the Reset Cursor before Operation field on the Peek Service tab to either:
*Yes The Peek service starts at the beginning of the queue and gets a copy of the first message.
*No The Peek service retrieves a copy of the next message in the queue relative to the last message that the Peek service retrieved.
Default: Yes
Note:
You can also set the value for the Reset Cursor before Operation field in the Pipeline Editor. If you add a value other than Yes or No in this field, then WebSphere MQ Adapter automatically sets the value to No.

An asterisk * indicates that if you set the dynamicQueuePrefix at run time, then you also need to set the queueName.

WebSphere MQ Adapter passes the following optional input properties from the MQMD Header tab in Designer to the input signature of the Peek service. The data types for the selectionCriteria properties are documented as they appear in Designer.
Also, if values are specified for these properties, then WebSphere MQ Adapter will only receive messages from the queue that match the specified criteria. For a complete description of the selectionCriteria properties and their uses, refer to IBM's WebSphere MQ user documentation.
