Many details of these steps have changed with the introduction of DB2 Universal Database for OS/390 Version 5.1. Most of these steps apply to SNA users, but some also apply to users who will connect to DB2 Universal Database for OS/390 via TCP/IP.

For a summary of the example VTAM names used throughout this book, see ªSample Network Element Names (VTAM)º on page 41. For TCP/IP names, see ªCon®guring TCP/IP for DB2 Universal Database for OS/390º on page 47.

Summary of Steps

In order to prepare DB2 Universal Database for OS/390 or DB2 for MVS/ESA to receive connection requests from DB2 Connect, you must complete the following steps at your DB2 Universal Database for OS/390 host:

Step 1. Verify that the following PTFs for OS/390 are installed:

vPTF UQ06843 for APAR PQ05771

vPTF UQ09146 for APAR PQ07537.

Step 2. Con®gure VTAM - see ªCon®guring VTAMº, or:

Step 3. Con®gure TCP/IP - see ªCon®guring TCP/IP for DB2 Universal Database for OS/390º on page 47, or:

Step 4. Con®gure DB2 Universal Database for OS/390 or DB2 for MVS/ESA

-see ªCon®guring DB2 Universal Database for OS/390º on page 44, or ªCon®guring DB2 for MVS/ESAº on page 45.

Con®guring VTAM

To con®gure VTAM, your VTAM Administrator needs to determine the names and options to be used on your system. The following de®nitions must be provided to enable the DB2 Connect workstation to connect to the host:

1.The VTAM APPL De®nition for DB2 Universal Database for OS/390 or

DB2 for MVS/ESA. (The APPL name (LU name) for the DB2 subsystem is NYM2DB2 in these examples.)

2.The VTAM PU and LU De®nitions for DB2 Connect. (The PU and LU de®nitions for the DB2 Connect workstation are NYX1 and NYX1GW01 respectively in these examples.)

3.The VTAM Log Mode De®nition for DB2. (The log mode entry to be used for the connection is IBMRDB in these examples.)

The sample VTAM de®nitions are provided in the sections that follow. These samples use parameters that match the parameters used elsewhere in this book.
