3.2.4.15 Local LU Initiated Recovery Sending XLN Error

This event MUST be signaled by the higher-layer business logic with the following arguments:

• A connection object of type CONNTYPE_TXUSER_DTCLURECOVERYINITIATEDBYDTC

• An Error Reason value, which MUST be set to one of the following values:

  • Log Name Mismatch

  • Cold Warm Mismatch

  • Protocol Error

If the Local LU Initiated Recovery Sending XLN Error event is signaled, the LU 6.2 implementation (section 3.2) MUST perform the following actions:

• If the provided connection state is not set to either Processing Cold XLN Request or Processing Warm XLN Request:

  • Return a failure result to the higher-layer business logic.

• Otherwise:

  • Send a TXUSER_DTCLURECOVERYINITIATEDBYDTC_MTAG_ERROR_FROM_OUR_XLN message using the provided connection:

    • The XlnError field MUST be set to one of the following elements of the DTCLUXLNERROR enumeration:

      • DTCLUXLNERROR_LOGNAMEMISMATCH if the provided Error Reason value is Log Name Mismatch

      • DTCLUXLNERROR_COLDWARMMISMATCH if the provided Error Reason value is Cold Warm Mismatch

      • DTCLUXLNERROR_PROTOCOL if the provided Error Reason value is Protocol Error

  • Set the connection state to Awaiting Request Complete.
