View the official Windows Driver Kit DDI referenceThe ZwRecoverTransactionManager routine reconstructs the state of the transaction manager object (including all transactions, enlistments, and resource managers) from the recovery information that is in the log stream.
TransactionManagerHandle [in]A handle to a transaction manager object that was obtained by a previous call to ZwCreateTransactionManager or ZwOpenTransactionManager. The handle must have TRANSACTIONMANAGER_RECOVER access to the object.
ZwRecoverTransactionManager returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:
| Return code | Description |
|---|---|
| STATUS_OBJECT_TYPE_MISMATCH | The specified handle is not a handle to a transaction manager object. |
| STATUS_INVALID_HANDLE | An object handle is invalid. |
| STATUS_ACCESS_DENIED | The caller does not have appropriate access to the transaction manager object. |
| STATUS_TM_VOLATILE | The transaction manager object is volatile and, therefore, its transactions cannot be recovered. |
| STATUS_UNSUCCESSFUL | The transaction manager object is not in a state that allows recovery. |
The routine might return other NTSTATUS values.
The ZwRecoverTransactionManager routine tries to reconstruct the state of the transaction manager object, including all transactions, enlistments, and resource managers, from the recovery information that is in the object's log stream, beginning at the last restart area that KTM created and ending at the stream's end.
To recover up to a specific virtual time, use the ZwRollforwardTransactionManager routine instead of ZwRecoverTransactionManager.
Your TPS component must call ZwRecoverTransactionManager after it has called ZwCreateTransactionManager or ZwOpenTransactionManager.
For more information about recovery operations, see Handling Recovery Operations.
NtRecoverTransactionManager and ZwRecoverTransactionManager are two versions of the same Windows Native System Services routine.
For calls from kernel-mode drivers, the Nt*Xxx* and Zw*Xxx* versions of a Windows Native System Services routine can behave differently in the way that they handle and interpret input parameters. For more information about the relationship between the Nt*Xxx* and Zw*Xxx* versions of a routine, see Using Nt and Zw Versions of the Native System Services Routines.
