Understanding the Virtual Workday

The virtual workday is a point in time each day that limits how far back Applications Manager will search in the Backlog and History. You can reset the virtual workday start time by running the install script and selecting Setups.

When Applications Manager evaluates a predecessor, it looks back in time for the most recent execution of that job or process flow. The virtual workday start time is used to determine how far back in time Applications Manager will look. For example, if you set the virtual workday for midnight each night, Applications Manager will check back only to midnight. The current virtual workday start time is displayed to the left of the status bar on the Explorer window as shown below.

Virtual Day for Tasks Determined by Their Original Start Time

A task's virtual day is determined by the original start time of that task or its parent process flow. The virtual day is not affected by the following factors:

When the task is inserted into the Backlog
When the task runs

The start time for scheduled tasks is their scheduled start time, not their staged start time.

Internal Predecessors

Internal predecessors exist within the same process flow. Therefore, the start time for all components in the process flow is always the same. For this reason:

Success since last run and Success only when FINISHED link types are not available for internal predecessors.
The virtual day never affects internal predecessors.

External Predecessors

Almost all external predecessors link types are subject to the virtual day. The only predecessor type that does not take the virtual day into consideration is the Success since last run type. For more information on predecessor link types, see Understanding Predecessor Execution Rules.

Setting the Virtual Workday Start Time

The virtual day start time is set when you install Applications Manager. To reset it to a different time, rerun the install. For UNIX run the awinstall script. For Windows run setup.exe. The install script will show you the current value for the virtual day and ask if it is correct. You can enter 'No' and update it.
