Glossary of Terms

AcuAccess

A server access file that defines system security. This file contains a database of access records that determine which machines and which users are allowed to use AcuLaunch. Depending on the construction of the database records, the server access file can provide many levels of system access, from very permissive to very restrictive.

ACUCOBOL-GT Thin Client

The client portion of the split runtime. The Thin Client must be installed on the Windows client machine before the first thin client connection is attempted.

acushare

A utility that is required for all UNIX installations that do not have an unlimited license. The acushare utility monitors and enforces the site license.

COBOL layer

A logical application layer that performs all application processing and resides on the application host or server.

Distributed processing

Environments where some application components are processed on the client and some on the server (and the application is engineered accordingly).

Remote COBOL listener

A thin client technology called AcuLaunch that listens for requests from the clients to launch the ACUCOBOL-GT runtime on the server. When a request is received, AcuLaunch starts a new runtime on the server, connects that runtime with the client process, and removes itself from the communication stream to wait for other requests from other enabled applications.

Server alias file

An association file holding all the information that will be needed to invoke the appropriate runtime on the server. This file is a text file in a format similar to ".ini" files, and it must be created before any thin client operation is attempted.

Server-side processing

An environment where all application components are processed on the server. Acucorp's thin client solution performs all processing on the server and passes simple screen commands between the client and the server. Because server hardware is usually faster and because data access on the server is local, application performance often improves when processing is performed on the server.

Split runtime

Rather than forcing you to split your application into client and server components, the ACUCOBOL-GT runtime has been split so that your existing application can be displayed on the client. The runtime portion that is installed on the thin client is known as the ACUCOBOL-GT Thin Client. The full ACUCOBOL-GT runtime is installed on the server. To function, the split runtime makes use of a "remote COBOL listener" on the server known as AcuLaunch.

Thin client computing

A network-based approach to information processing. With Acucorp's enabling thin client technologies, your software can display on Windows front-end clients, access COBOL programs in practically any server operating environment, permit local or remote printing, and allow remote debugging from Windows.

User interface (UI) layer

A logical application layer that handles screen, mouse, and keyboard activity, and executes on the display host.
