BEA TUXEDO System-supplied Subroutines
The BEA Tuxedo system-supplied subroutines, TPSVRINIT and TPSVRDONE, must follow certain rules when used in transactions.
The BEA Tuxedo system server calls TPSVRINIT during initialization. Specifically, TPSVRINIT is called after the calling process becomes a server but before it starts handling service requests. If TPSVRINIT performs any asynchronous communication, all replies must be retrieved before the function returns; otherwise, the system ignores all pending replies and the server exits. If TPSVRINIT defines any transactions, they must be completed with all asynchronous replies retrieved before the function returns; otherwise, the system aborts the transaction and ignores all outstanding replies. In this case, the server exits gracefully.
The BEA Tuxedo system server abstraction calls TPSVRDONE after it finishes processing service requests but before it exits. At this point, the server's services are no longer advertised, but the server has not yet left the application. If TPSVRDONE initiates communication, it must retrieve all outstanding replies before it returns; otherwise, pending replies are ignored by the system and the server exits. If a transaction is started within TPSVRDONE, it must be completed with all replies retrieved; otherwise, the system aborts the transaction and ignores the replies. In this case, too, the server exits.
