Use this method to specify the details of queue processors that run in your application.
Optional. Identify the class of the work item or other item that is to be processed. This page is available later as context to the queue processor activity that processes the item, for example:
- If the queued item refers to a work item, set the step page to the work
- If the queued item is an assignment, set the step page to the assignment
- If the Step Page value in the step is blank, the primary page of the calling activity is used.
This method has the following parameters:
|Field name||Available field values||Description||Default value|
|Type of queue||Standard||An item is queued to a standard queue processor. You do not need to create a new queue processor.||Standard|
|Dedicated||An item is queued to a custom queue processor.|
|Queue processor||Press the Down arrow key to view the list of available queue processors.||A name of the queue processor to which items are queued.||N/A|
|Date/time for processing||A DateTime property in the class of the step page.||This option is available for dedicated queue processors only. A DateTime property by which you specify when a dedicated queue processor resolves the activity. The property represents the time after which an item can be processed.||N/A|
|Activity name||Press the Down arrow key to view the list of available activities. Enter parameter values in the appropriate fields.||A name of the activity that is resolved by the queue processor. When you enter the name of the activity, the parameters for that activity are displayed.||N/A|
|Lock using||Primary page||Open a page by using a pzInskey property and lock it. This page is available to Processing activity as pyQueuePage.||Primary page|
|Key defined on property||Open a page by using a key defined on a property. This page is available to Processing activity as pyOtherPage. You need to enter a name of the property.|
|None||Open a page without a lock from the database by using the pzInskey property.|
|Write now||No||The message is queued as a part of the next database commit.||No|
|Yes||The message is queued immediately and is not a part of any transaction.|
|Timeout to acquire lock (in minutes)||Number of minutes greater than 0||The system attempts to acquire the lock every minute until the specified value is reached. The system increases the retry attempt counter when the time-out value is reached.||30|
|Number of minutes less than 0||The system attempts to acquire the lock every minute and does not treat retries as failed attempts. The system does not increase the retry attempt counter.|
|0||The system treats a failed lock try as a failed attempt and increases the retry attempt counter.|
|Queue current snapshot of page||No||When a page that has a pzInskey property is queued, the message stores the pzInskey value only. When an item is processed by using the pzInskey property, the corresponding record from the database opens.||No|
|Yes||The message that is queued stores the entire page. This is an
advanced option that you can use for performance
This option is available only when locking is set to None.
|Alternate access group||Press the Down Arrow key to prompt the list of available access groups.||Define an alternate access group when you want to process the item in a different context from the access group that is defined in the queue processor.||N/A|
The system queues the page to the embedded Kafka data instance. This occurs
immediately or at the next Commit method run, depending on the Write
Now setting. The queue processor picks up this item from the queue
and processes the activity configured. A unique ID is generated to represent the
ItemID and is available on the parameter page as the parameter,
When a queue processor tries to process an item for the number of times that you specify in the MaxAttempts parameter, and the queue processor is not successful, the item is moved to the broken queue. You can view the list of broken items in Admin Studio, on the Queue Processor landing page. To view the list of the broken items, you must have the pzQueueProcessorObserver privilege. To resubmit or delete items from the broken queue, you must have the pzQueueProcessorAdministrator privilege.
