An apparatus provides an operating system service that receives, from an application in a batch environment, a plurality of database transactionality calls associated with a first program of the application, the first program having a first addressability mode. In response to at least one of the plurality of database transactionality calls, the operating system service provides a shared database connection to a database for the first program of the application and for a second program of the application that has a different and second addressability mode. In some implementations, the operating system service provides the shared database connection using one or more of a plurality of callable database transactionality classes, such as a plurality of callable Java classes in a Java archive (JAR) file.

Method and apparatus for proving a shared database connection in a batch environment

A computer program product and program storage device for incorporating an external predefined procedure into an existing unit of work. The existing unit of work is part of a client application process, wherein the client application process is not able to execute external programs. A logical representation of the client application process is created in a database environment. The logical representation is disconnected from the client application process, and is connected to a procedure operating environment capable of executing external programs. The external predefined procedure is caused to executed in the procedure operating environment. Then, the logical representation is reconnected to the client application process.
