3.2.4.1 Adding an LU Name Pair

This event MUST be signaled by the higher-layer business logic with the LU Name Pair argument.

If the Adding an LU Name Pair event is signaled, the LU 6.2 Implementation MUST perform the following actions:

  • Initiate a new CONNTYPE_TXUSER_DTCLUCONFIGURE connection using the Transaction Manager Name field of the LU 6.2 Implementation.

  • Send a TXUSER_DTCLURMCONFIGURE_MTAG_ADD message using the connection:

    • The cbLength field of the DTCLU_VARLEN_BYTEARRAY structure (contained in the LuNamePair field) MUST be set to the number of bytes in the provided LU Name Pair.

    • The first cbLength bytes of the rgbBlob field of the DTCLU_VARLEN_BYTEARRAY structure (contained in the LuNamePair field) MUST be set to the provided LU Name Pair.

  • Set the connection state to Awaiting Add Response.
