• These servers are managed in the TUXEDO environment. Figure 1‑1 illustrates the flow of data when a tpcall () is issued from a TUXEDO client to an WebSphere MQ application.The TMQUEUE _MQM server handles tpenqueue() and tpdequeue() requests from clients who want to place messages on WebSphere MQ queues. Figure 1‑2 shows the enqueuing and dequeuing message flows:The WebSphere MQ to Tuxedo server (TM_MQI), processes service requests from WebSphere MQ applications to TUXEDO servers. Figure 1‑3 illustrates the data flow for inbound requests:Figure 1‑3 Data Flow for Inbound Service RequestsThe WebSphere MQ to Tuxedo server (TM_MQI) monitors specified queues for requests. When TM_MQI receives a request, it issues a tpcall() request to the designated server. It then places the response data in the reply queue specified in the original request
