Types of Task
Analysis Tasks
Analysis tasks run analysis on a number of streams.
Archive Tasks
An Archive Task can be created to archive data no longer needed in PhixFlow for processing. When a Stream is archived, PhixFlow creates an Archive Log with useful details of the data archived. Optionally, the archived data can be saved to a file. If this is done, the data can reloaded into PhixFlow using Restore Archive.
If you set up an archive task with no stream added, all streams configured for archive will be archived by this task, unless this stream has been added to another archive task. Even if you set up a catch-all archive task in this way, you might still want to have separate archiving for certain streams if they contain large amounts of data for each run, in which case archiving can sometimes task a while - this means you can schedule archiving for these streams in particular at a time when you system is quiet.
Rollback Tasks
A Rollback Task can be created to roll-back one or more streams. On execution, it fully rolls back all data in the stream, deleting the stream-sets.
System Tasks
A System Task performs system-wide housekeeping activities. These include deleting:
- and optionally archiving log messages
- managed file entries
- email entries
- temporary files created by file exporters to send by email
- data from incomplete stream sets.
The System Task should be run daily, or at a minimum every week. If incomplete stream sets are not deleted, they can slow down PhixFlow's performance. Depending on your PhixFlow database, queries that have to exempt many incomplete stream sets can reach system limits. This can prevent PhixFlow and its applications from running.
The archiving periods, and whether to archive log messages before they are deleted, are controlled by the following parameters in System Configuration:
- Delete Log Messages After Days
- Archive Deleted Log Messages To File
- Delete Statistics After Days
- Delete Emails After Days
Task Properties
For information about the properties toolbar, and about the sections Parent Details, Analysis Models, Description and Audit Summary, see Common Properties. We recommend you always add a Description that explains the purpose of the item you are creating.
For a full list of all the PhixFlow property tabs and windows, see Properties, Windows, Menus and Toolbars.

Streams
This section is only available for analysis tasks and archive tasks. The grid shows the list of streams assigned to the task.
There are different ways you can add streams to the list.
- From a model, hover your mouse pointer over the stream to display the pop-up toolbar. Click
Drag Object and drag it into the grid. - From the repository, click Error rendering macro 'excerpt-include' : No link could be created for '_streams_show'.to display the list of the streams in the repository. Drag a stream from the list into the grid.
- From the stream properties, drag the icon into the grid.
Remember that for archive tasks, if no streams are added, all streams that have archiving configured will be archived, unless they have been added to another archive task.
