A.2 Multiple-Tier Installation

AcuODBC is able to access COBOL data files located on a stand-alone or networked environment as well as on a remote UNIX or Windows NT (Intel) server.

To access remote files in a client/server environment, AcuODBC takes advantage of AcuServer, the Acucorp product that allows you to manage a remote Vision file system. It also uses WSOCK32.DLL to open communications between your Windows computer and the server. WSOCK32.DLL is usually installed with your TCP/IP software.

Installing AcuODBC in a multiple-tier environment is the same as installing it in the standard, single-tier environment, with the following exceptions:

1. You must have WSOCK32.DLL installed on your Windows client. This is a TCP/IP dynamic link library that allows you to communicate with any vendor's TCP/IP stack. It typically resides in your Windows directory. If you don't have WSOCK32.DLL, you can purchase it from FTP Software, Inc., or anyone who provides TCP/IP software.

2. You must install AcuServer on the server as described in the AcuServer User's Guide. The AcuServer User's Guide can tell you what hardware and software components are necessary for AcuServer.

Once AcuODBC is installed, be sure to create data source names (DSNs) for your Vision or relative data files as described in Section 3.1 Data Source Names (DSNs). For a list of the files installed, refer to the READ.ME file on your AcuODBC installation disks.
