4.1.2 Sending the TXUSER_TIPPROXYGATEWAY_MTAG_PULL2 Message

  • Article

To request the TIP pull propagation of a transaction, the TIP interoperability application sends a TXUSER_TIPPROXYGATEWAY_MTAG_PULL2 user message that contains the TIP URL of the transaction to be pulled. Each field in the message aligns to a multiple of 4 bytes. The message also specifies whether the pull propagation is synchronous or asynchronous. In the example message that is shown below, the following values are also assumed:

  • TIP transaction identifier: "tip://computedesk1/?OleTx-757fda7b-aa73-4179-aa55-131b22c43db5"

  • Asynchronous operation: 0
