## The Periodic Alert Item Type

The Error Check process is associated with an item type called Periodic Alert. This item type identifies all processes associated with implementing periodic alert functionality through Oracle Workflow. Currently there are two workflow processes associated with Periodic Alert: Error Check and User Defined Alert Action.

If you examine the property page of Periodic Alert, you see that it has a persistence type of Temporary and persistence number of days of 0. This means that the run time data associated with any item instances for this item type are eligible for purging as soon as they complete. A Selector function is not specified because the process to start is specified when you initiate a Periodic Alert process from the web-based interface.

The Periodic Alert item type also has several associated attributes. These attributes record information provided when you initiate a Periodic Alert process. The attributes are used and maintained by function activities as well as notification activities throughout each process.
