PutQueue operation
The PutQueue operation puts a message on a first-in first-out (FIFO) or last-in first-out (LIFO) IBM i data queue.
When the PutQueue operation is performed by the adapter, a message is added to a data queue. Where the message is placed on the queue depends on the type of data queue such as FIFO or LIFO as defined on the IBM i system. The adapter supports two data queue types with the PutQueue operation: First-in first-out (FIFO) and Last-in first-out (LIFO). Messages added to a FIFO data queue are placed at the bottom of the queue and are the last in line to be processed by the IBM i system. Messages added to a LIFO data queue are placed at the top of the queue and are the first in line to be processed by the IBM i system.
To process the PutQueue operation, the adapter performs the following actions:
- Receives a request in the form of a business object
- Connects to the IBM i system
- Converts information received from the business object into a message format
- Adds the message to the IBM i data queue
