Configuring Custom Actions

4. If you selected the Advanced control type, optionally select an item from the
Timing drop-down list which best describes the order in which you want this
custom action to run with your other custom actions. Table 3-4 describes the timing
options. If the timing does not matter, keep the Default setting.
N O T E
Timing does not affect the order in which custom actions
run with other Active Upgrade tasks. Use this option only
if you want to ensure that one custom action runs before
or after another custom action.
Advanced Executes the custom action during every step of the Active Upgrade
process, including interim steps such as PrepareSplit and
PrepareMerge, which occur prior to the Split and Merge operations.
This control type allows you to have more precise control over a
custom action. Your executable file runs each time the upgrade
process switches states, but you can write a program with conditional
statements based on Active Upgrade environment variables to specify
exactly when and where particular tasks should be executed. For
example, you can write a conditional statement that triggers only on
the Upgrade Side if the system is in merge mode. See
“Using Active
Upgrade Environment Variables” on page 3-16 for more information.
If you have more than one custom action, the Advanced control type
also allows you to control the order in which the custom actions are
executed (step
4 ).
Backup Executes the custom action when the system is merged, allowing you
to back up files that were modified on the Production Side system disk
while the system was in split mode (before these files are lost during
the commit process).
Table 3-4. Timing for the Advanced Control Type
Timing Purpose
Default Executes the custom action in the default, consecutive order.
Early Executes the custom action early in the list of custom actions, before
items marked as Default or Late.
Late Executes the custom action late in the list of custom actions, after
items marked as Early or Default.
