A client system utilizes a standard browser component and a transaction protocol gateway (TPG) component that operatively couples to the standard browser component. The browser component initiates the utilization of new session connections and reuse of existing session connections as a function of the coding of the universal resource locators (URLs) contained in each issued request. Each URL is passed to the TPG component that examines a context field included within the URL. If the context field has been set to a first value, the TPG component opens a new session connection to the server system and records the session connection information in a persistent session table (PST) component maintained by the TPG component. If the context field has been set to a second value, then the TPG component obtains the session connection information in the PST component for the established session connection and passes the data from the browser component to the server system over the existing persistent session connection.

Method and system for providing high performance Web browser and server communications

A data communications system for supporting World Wide Web (WWW) database queries to enterprise level databases utilizes two server based programs. A first program retrieves and transmits a specified version of a specified form to an intermediate forms program. The second program has two modes of operation. In either mode, database queries to the enterprise level database are performed and results transmitted. However, in a first, standard, mode of operation, a specific version of a specific form is read from a forms database and transmitted to the requester along with the query response. In the second mode of operation, only the database query results are transmitted, along with a modified header that specifies the appropriate form. The corresponding forms are retrieved from a local forms database and merged with the query response before being displayed by a Web browser. Missing forms are requested from the Web forms program and cached for subsequent requests.

Instrumentation statistics are tallied at the procedure level in instrumentation stack frames corresponding to subroutine stack frames. Elapsed CPU time for each entry into a procedure is computed and accumulated into a statistics table corresponding to that procedure. Also accumulated into that statistics table are the accumulated elapsed execution times of the subroutines called by this procedure. These values are initially accumulated into the instrumentation stack frame for each subroutine's parent upon subroutine exit, and then accumulated into the statistics table upon subroutine exit of the parent. Elapsed CPU time is computed by subtracting CPU time of last dispatch from the current hardware clock, then adding this to an accumulated CPU time at the time of dispatch.

Method and data processing system for providing subroutine level instrumentation statistics

A method for addressing mass memory in which information is stored in control intervals of physically contiguous disk segments subject to irregularities in the mapping is disclosed. Such irregularities may include discontinuities at some regular interval, which may or may not be 2', and/or offset from zero with respect to a virtual address employed by a user. Within the method, a unique hashing algorithm is employed to convert a virtual address to a physical address taking into account such irregularities in the mapping. This algorithm is particularly characterized by its use of integer binary arithmetic which results in high speed and complete accuracy. For the special and common condition in which discontinuities appearing at some regular interval of 2', a similar disclosed algorithm may be employed to achieve even greater speed of address transformation.
