Introduction

The Adabas Bridge for DL/I (ADL) is Software AG's tool for the migration of DL/I or IMS/DB databases into Adabas. DL/I applications can continue to run without any change. The migrated data can be manipulated by Natural, Software AG's fourth generation language. The migrated data can be accessed by SQL applications, if the Adabas SQL gateway is available. ADL can also be used to run standard DL/I applications on Adabas sites.

The Adabas Bridge for DL/I runs under z/VSE and z/OS. It can execute concurrently in both batch and online environments supporting CICS and IMS/TP.

ADL consists of the following major functional units:

The conversion of data definitions and databases is described in the ADL Conversion documentation. The installation and operation of the interfaces is covered by the ADL Interfaces documentation. In particular, this documentation describes the installation of the ADL Interfaces directly related to the TP monitor in use.

The ADL Messages and Codes documentation comprises a list of all error codes and messages issued by ADL together with a glossary of terms related to DL/I, Adabas and ADL.

The ADL Installation documentation is intended for the system programmer in charge of the ADL installation. The installation process requires familiarity with the operating system in use. No particular knowledge of either data base system involved is required.

This documentation applies to both z/OS and z/VSE operating systems. References valid for only one operating system are clearly marked as such. The term "DL/I" is used as a generic term for IMS/VS and DL/I DOS/VS.
