Abstract
Abstract The preferred embodiment provides an improved system and method for registration of Resource Managers with Transaction Managers in an distributed processing environment. The preferred system and method creates and stores a transactional resource in a container when the first execution method goes to the Resource Manager. The transactional resource represents the Resource Manager to the Transaction Manager. The transactional resource uses X/Open static registration procedures to inform the Resource Manager about the new transaction. The transactional resource is then registered to the Transaction Manager. In this way, only those Resources Managers that are involved in a transaction are registered and made known to registered to the Transaction Manager. Additionally, because static registration procedures are used, the Transaction Manager maintains control of the transaction
