Installation Requirements

To operate the Extender for Db2, the following hardware is required.

• An IBM or IBM-compatible mainframe supporting z/OS 2.1 or higher operating systems.
• A minimum of 240 Cylinders of 3390 DASD device for the qualif.HOME.LOAD data set containing the Extender for Db2 interface load modules, the IBM Db2 module entry-points, the Extender for Db2 main module, and other Extender modules.

To operate the Extender for Db2, the following minimum software levels are required.

• Server for z/OS, Version 7.7 or higher

• Db2 v11 or higher
• z/OS 2.1 or higher

When using the Extender for Db2 with a Db2 application product, see the documentation of that product for any additional requirements.

The following data sets are needed for the installation of the Extender for Db2.

qualif.HOME.LOAD

qualif.HOME.DATA

Note: If a PDS Deployment z/OS Server is installed in the same LPAR, you can use the existing qualif.HOME.LOAD library for the Extender for Db2.

Before you install the Extender for Db2, you should have access to a server, with all related data adapters and communications files installed. The server is not required for the Extender for Db2 installation procedure. However, for the Extender to function as a working client, communications between the Extender and the server are essential. For more information about setting up communications, see the Server Administration manual.

You must install the Distributed Data Facility (DDF). Otherwise, the QMF Draw functionality (which checks the CSECT for the presence of DDF) fails. For more information on whether you have DDF installed with your Db2 subsystem, see your system administrator.
