Restriction:This topic applies only when a Database Connectors license has been installed via the
Micro Focus License Management System.
This section describes the concept of
Database Connectors interfaces, and how to configure access to relational database management systems from COBOL.
Database Connectors Overview
This section provides an overview of Micro Focus Database Connectors for Visual COBOL 3.0, and how you can use its interfaces to bridge the worlds of COBOL and Structured Query Language (SQL).
Getting Started
This section is designed to get your started using Database Connectors after your installation.
XFDs
This section explains the importance of Extended File Descriptors (XFDs), and how you understand and create them.
Using XFD Directives
This section explains what XFD directives are, and how you can use them in your COBOL File Descriptors (FDs) to control how your database tables are built.
Invalid Data
This section lists the COBOL data items that are considered invalid, and explains what happens to them when they are stored in the database. This section also covers database items that are considered invalid, and explains how those are translated to COBOL.
Working with COBOL
This section explains how to prepare your COBOL programs for use with Database Connectors.
New and Existing Databases
This section explains how to handle your data in both existing and new databases.
File Handling Configuration
This section explains how to configure COBOL file handling operations to interact with supported RDBMS.
Run Time System Configuration Database Connectors uses an ACUFH configuration file to determine how the run time system should behave when interacting with data. This chapter describes how to configure the File Handler, and how to use ACUFH configuration variable options to configure the run time system for your relational database environment.
Database Connectors for DB2
This appendix provides information that is specific to Database Connectors for DB2.
Performance and Troubleshooting
This section provides some guidelines into improving performance when using Database Connectors. It also provides some reference topics to help troubleshoot some common problems.
Questions and Answers
This section contains some answers to commonly asked questions, which apply to any of the relational database management systems you are using.
