A buffer accessible by an application executing under an application server in a first address space is managed by a database adapter executing in a second address space. A data request from the application executing in said first address space, comprising a buffer locator in the empty state, is received by the database adapter executing in the second address space. A buffer is allocated in the first address space and the address of this buffer is stored in the buffer locator. Data associated with the data request, received from a database subsystem, is copied to the buffer. Control is then transferred back to the application whereby the application utilizes the buffer locator to access the buffer and process the data contained therein. A database adapter automatically managing application buffers across address spaces in accordance with the present invention may be referred to as an 'auto-buffer database adapter'.

Method, computer program product, and system for automatic application buffering

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). A TOC Connector for Java interfaces the JVM to the TOC, wherein the TOC Connector for Java includes one or more objects for establishing a connection between an applet or servlet executed by the JVM and the OTMA of the DBMS, so that transactions can be transmitted from the application program to the DBMS over the established connection and results of the transmitted transactions can be received at the application from the DBMS.

System message objects for communicating between an application and a database management system

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.

IMS web studio taskguide

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.
