String Variable to Change an Existing Context Variable
You can add a string variable to change preexisting context variables. Some of these variables are not exposed in the interface elsewhere, but you can change their values.
For example, the context variable, ARCHIVE_DETECTION_FREQUENCY, is the periodic interval for detection of deployed archives. The default value for this interval is 30 seconds. The broker uses this data to synchronize the archive with scaling rules.
For this example, if your archive takes longer than 30 seconds to start and respond, then you would set the value higher than the time needed to deploy and start that archive.
Changes to variables are optional and implementation dependent, because all variables have default values that are usually appropriate for the most common use cases.
Variable values from the Enabler can be changed as well. Use the Add from Enabler button to change values of Enabler-specific context variables.
