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.
