3.2.4.18 Local LU Initiated Recovery Sending Compare States Query

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

• A connection object of type CONNTYPE_TXUSER_DTCLURECOVERYINITIATEDBYDTC

If the Local LU Initiated Recovery Sending Compare States Query 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 Warm XLN Request or XLN Exchange Complete:

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

• Otherwise:

  • If the connection state is Processing Warm XLN Request:

    • Send a TXUSER_DTCLURECOVERYINITIATEDBYDTC_MTAG_CHECK_FOR_COMPARESTATES message using the provided connection.

    • Set the Early Compare States Check Done field of the connection object to TRUE.

    • Set the connection state to Awaiting Response To Compare States Query During Warm XLN.

  • Otherwise, if the connection state is XLN Exchange Complete:

    • Send a TXUSER_DTCLURECOVERYINITIATEDBYDTC_MTAG_CHECK_FOR_COMPARESTATES message using the provided connection.

    • Set the connection state to Awaiting Response To Compare States Query.
