JetOSSnapshotAbort Function

The JetOSSnapshotAbort function notifies the engine that it can resume normal IO operations after a freeze period ended with a failed snapshot.

Windows Server 2003: JetOSSnapshotAbort is introduced in Windows Server 2003.

    JET_ERR JET_API JetOSSnapshotAbort(
      __in          const JET_OSSNAPID snapId,
      __in          const JET_GRBIT grbit
    );

Parameters

snapId

The identifier of the snapshot session.

grbit

The options for this call. This parameter is reserved for future use and the only valid value supported is 0 (zero).

Return Value

This function returns the JET_ERR datatype with one of the following return codes. For more information about the possible ESE errors, see Extensible Storage Engine Errors and Error Handling Parameters.

Return code	Description
JET_errSuccess	The operation completed successfully.
JET_errInvalidParameter	The snapshot session is invalid or the grbit parameter is invalid.
JET_errOSSnapshotInvalidSnapId	The identifier for the snapshot session is not valid.

If this function succeeds, the snapshot session will end and the normal engine behavior will resume. A new snapshot session can be started at a later point.

If this function fails, the snapshot session will not be aborted.

Remarks

This function should be called instead of JetOSSnapshotThaw to inform the engine that the snapshot was aborted for reasons that don't relate to the engine. This information can be used later to help issue event log messages about the snapshot session or to help determine other appropriate actions.
