During the execution of a business process, if the machine with an execution platform stops, or if invocation of service components fails, then a fault occurs and you can re-execute the interrupted process instance. Business process contents can be processed by re-executing the process instance.

The conditions for re-executing a process instance are as follows:

• When the HCSC server is started
• When a business process is started
• When synchronous(SessionBean) standard reception is started
• When asynchronous (MDB (WS-R)) standard reception is started in an environment that uses Reliable Messaging

Statuses to be re-executed are as follows:

Process status	Activity
	Type	Status
Executing	Invoke service	Executing
Error	Invoke service	Error
Executing	Standby	Executing
Executing	Scope	(Executingwait)
Error	Scope	Error
Executing	Scope	(Completedwait)
Executing	Response	(Completedwait)
