NAME

CosTransactions_RecoveryCoordinator - This module implements the OMG CosTransactions::RecoveryCoordinator interface.

DESCRIPTION

To get access to the record definitions for the structures use: .br -include_lib("cosTransactions/include/CosTransactions.hrl").

EXPORTS

replay_completion(RecoveryCoordinator, Timeout, Resource) -> Return

Types
RecoveryCoordinator = #objref
Timeout = integer(), milliseconds | 'infinity'
Resource = #objref
Return = Status | {'EXCEPTION', E}
E = #'CosTransactions_NotPrepared'{}
Status = atom()

The RecoveryCoordinator object is returned by the operation CosTransactions_Coordinator:register_resource/3. The replay_completion/2 may only be used by the registered Resource and returns the current status of the transaction. The operation is used when recovering after a failure.
Possible Status replies:

*
'StatusCommitted'


*
'StatusCommitting'


*
'StatusMarkedRollback'


*
'StatusRollingBack'


*
'StatusRolledBack'


*
'StatusActive'


*
'StatusPrepared'


*
'StatusUnknown'


*
'StatusNoTransaction'


*
'StatusPreparing'


Warning:
replay_completion/3 is blocking and may cause dead-lock if a child calls this function at the same time as its parent invokes an operation on the child. Dead-lock will not occur if the timeout has any value except 'infinity'.

If the call is external incoming (intra-ORB) the timeout will not be activated. Hence, similar action must be taken if the Resource resides on another vendors ORB.
