Abstract: A method, apparatus, and article of manufacture for accessing a database management system. A database management system (DBMS), executed by a server computer, manages one or more datastores stored on the computer. The DBMS includes an Open Transaction Manager Access (OTMA) that provides a high level application programming interface (API) for an application program to access the DBMS and its datastores, wherein the OTMA allows the application program to create an authorized connection with the DBMS. The server computer also executes a TCP/IP OTMA Connection (TOC) that establishes and manages connections between the DBMS and the application program. In the preferred embodiment, the application comprises a Java servlet or applet executed by a Java Virtual Machine (JVM).

Abstract: The present invention is a method and system for ensuring client access to paired and unpaired response messages. In the method, the server detects one or more unpaired message which are stored in a data structure on the server. The data structure may be created when the server is started or automatically when the first unpaired message is identified. The method then uses a communications protocol between the client and server which allows the client to request one or more of the stored unpaired messages. The system of the present invention uses a request module configured to receive a client request and prepare the client request for a response generator. The response generator receives the client request from the request module and generates an appropriate response. Next, an unpaired message module analyzes the response message generated by the response generator and distinguishes a paired message from an unpaired message.

Abstract: A method, apparatus, and article of manufacture for accessing a database management system. An application programming interface (API) provides a plurality of simplified procedures that allow an application program executed by the computer to access a database management system (DBMS) by creating an authorized connection between the application program and the DBMS. The application program invokes the simplified procedures of the API, the invoked procedures generate at least one supervisor call (SVC) interrupt that transfers control to an SVC Service Routine, and the SVC Service Routine connects to a Cross Coupling Facility (XCF) that interfaces to an Open Transaction Manager Access (OTMA) component of the DBMS.

Abstract: A method, apparatus, and article of manufacture for generating program specifications for a computer program that accesses datastore persistent objects materialized from a datastore. A "wizard" or "task guide" is displayed on a monitor attached to a computer, wherein the wizard comprises a step-by-step procedure for creating the program specifications. Operator input is accepted into the computer in response to the step-by-step procedure and the program specifications are created using the operator input.

Abstract: IMS Web provides for a method and apparatus which enables a user to communicate with IMS-based applications using a Web Browser. An input HTML form is used to associate IMS transaction data which is then supplied to a CGI-BIN program which uses IMS Web generated C++ class definitions to determine classes for each logical page. The CGI-BIN program interacts with the IMS database through an TCP/IP OTMA adapter and an output HTML communicates with the Web client.
