To enable session failover, you must configure the Oracle Commerce Platform to back up the values of specific properties after each request, so that these values can be restored when a failed session is recreated. Set the backingUpSessions property of the /atg/dynamo/Configuration component to true, and set the sessionBackupServerPropertyList property of the component to a comma-separated list of the properties to back up. For example:
backingUpSessions=true
sessionBackupServerPropertyList+=\
/atg/userprofiling/ProfileFailService.uidForFailover,\
/atg/dynamo/security/UserFailService.savedPersonae,\
/atg/commerce/ShoppingCart.restorableOrders,\
/atg/userprofiling/ProfileFailService.activePromotions,\
/atg/commerce/catalog/comparison/ProductList.items,\
/atg/commerce/gifts/GiftlistFormHandler.eventName
For more information, see Enabling Component Backup in the Configuring for Production chapter.
