To request the TIP push propagation of a transaction, the TIP interoperability application sends a TXUSER_TIPPROXYGATEWAY_MTAG_PUSH2 user message that contains the identifier of the transaction and the TIP URL of the TIP transaction manager where the transaction is to be pushed. Each field in the message aligns to a multiple of 4 bytes. In the example message that is shown below, the following values are assumed:
