NEC 320Fc manual Backup, Timing for the Advanced Control Type Purpose

Configuring Custom Actions

Table 3-3. Control Types for Custom Actions (Continued)

Control Type	Purpose
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).

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 3-4describes 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.

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.
