Abstract: A computer system and process efficiently provides resource recovery for a failure during a commit procedure. An application is run on a processor and requests a work operation involving a resource such as a protected conversation with another application in a different real machine. A commit procedure is begun for the work request, and if the commit procedure fails before completion, the following steps are taken to optimize the use of one or both of the applications. At some time after the commit procedure fails, a return code is sent to at least the application that initiated the commit indicating the result of the application commit order and that the application can continue to run and does not have to wait for resynchronization (recovery). Then, while the initiating application continues to run and do other useful work, resynchronization is implemented in parallel, asynchronously.

Abstract: END USER DATA STREAM SYNTAX Disclosed is a communication transport message format for carrying control information, relevant only to a transport system and end user data. The end user data is prefixed by a length field. The length field is set to a value representing the number of bytes of user data plus the size of the length field. A bit in the length field is used as a "continuation" or more-to-come indicator. Length field values that are less than the number of bytes of the length field are used to prefix control information.

Abstract: A method of providing a non-disruptive recovery of communication sessions in a communication system which includes a number of host systems (101, 102,...) each communicating via sessions with other devices and other different connections, (141, 142...) and in which the sessions assigned to a failed connection are suspended for a first and second time period and non-destructively moved to an alternate connection when a unique command is issued by one of the host systems and received by a control unit (130) involved in the failed connection.

Abstract: A Transport Layer Protocol Boundary (TLPB) architecture is described which will permit an application program to run over a non-native transport protocol without first generating a protocol compensation package tailored to the transport protocols assumed by the program's application programming interface and by the available transport provider. All transport functions required by the program are converted to standardized or TLPB representations. When a connection between the first application program and a second remote application is requested, the individual required TLPB transport functions are compared to corresponding functions supported by the transport provider. Compensations are invoked only where there is a mismatch. The node on which the remote application program runs is informed of the compensations so that necessary de-compensation operations can be performed before the data is delivered to the remote application program.
