Abstract
Data integrity is maintained in an environment in which multiple instances of a software component each can include multiple processes capable of accessing a shared resource. Each instance of the software component can be either an 'active' instance (which is allowed to update data) or a 'standby' instance (which is not allowed to update data). At any point in time, the environment does not comprise more than one active instance. There can, however, be more than one standby instance. Preferably, a single standby instance can become a new active instance in the event of a complete failure of the active instance, i.e. a failure associated with every process of the current active instance.
