CosTransactions_RecoveryCoordinator.3erl
This module implements the OMG CosTransactions::RecoveryCoordinator interface.
Description
To get access to the record definitions for the structures use:
-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.
