Abstract: Techniques are disclosed for combining multiple benchmarks for use in assessing characteristics of a computing system. For example, a method for configuring and running multiple benchmarks includes the following steps. A multiple benchmark specification is obtained. The multiple benchmark specification includes multiple individual benchmark specifications and a multiple benchmark workflow describing an ordering according to which the multiple individual benchmarks are to be configured and run. The multiple benchmarks are configured and run according to the ordering identified in the multiple benchmark workflow. Results of the multiple benchmark runs are recorded. One or more specifications or results associated with at least one of the multiple benchmarks are utilized as part of a benchmark specification for at least another of the multiple benchmarks so as to provide consistency between at least the one and the other of the multiple benchmarks.

Abstract: A gateway provides communication of tightly coupled XA transactions to a server hosting a DBMS and makes efficient use of domain socket pairs to implement demultiplexing in the gateway. The gateway includes a TCP/IP listener process which accepts connection requests from a transaction manager. Logical agents represent the application connection and are managed by a logical agent scheduler and are passed within the gateway using domain socket pairs. Gateway agents are dedicated to identified tightly coupled XA transactions to provide tightly coupled XA transaction support for DBMS systems which do not provide such support directly. The domain socket pairs in the gateway are assigned to logical agent schedulers and are available in a domain socket pool. A wait queue is provided to buffer logical agents when connection to the server is not available or where there are no domain socket pairs available in the domain socket pool. The wait queue is itself implemented as a domain socket pair.

Abstract: A user inquiry facility and method are described for use in a computerized data processing system which provides for monitoring of conversations or information transmission between a user of the data processing system, during the execution of the user's program, and a communication partner (which could include a database or other facility) associated with the data processing system. Task progress tracing information is selected from the conversations and stored. The stored information is updated to keep it current with the progress of the task of the user's program. An instruction is provided by the facility or method which, when activated, by the user selects task progress tracing information from the stored information and after formatting it for readability is transmitted to the user-s display or terminal.

Abstract: A system for processing diverse and non-diverse result sets is described. The system includes a client process in a client computer system that constructs a client process execution request identifying a stored procedure and specifying constraints on the quantity of response data that the client process is capable of handling. The client process execution request is transferred from the client process in the client computer system to a server process in a server computer system. The server process invokes the stored procedure identified by the client process execution request. Execution of the stored procedure results in the generation of answer set data for a plurality of diverse query result sets. Result set generators obtain answer set data for X of the query result sets, where X is defined by the constraints. The server process then generates an initial response containing, for each of the X query result sets, an amount of the obtained answer set data consistent with the constraints.
