Collecting Information

Before you can use DB2 Connect over a TCP/IP connection, you must collect information about both the host database server and the DB2 Connect workstation. For each host server that you are connecting to via TCP/IP, you must have the following information:

vThe location of the TCP/IP services ®le at the DB2 Connect workstation:

±On a UNIX system, the location of this ®le is usually /etc/services.

±On OS/2 Warp Version 4 the location of this ®le is determined by the ETC environment variable.

±On Windows NT, the location of this ®le is <NT install directory>\system32\drivers\etc\services.

vThe location of the TCP/IP hosts ®le at the DB2 Connect workstation:

±On a UNIX system, the location of this ®le is usually /etc/hosts.

±On OS/2 Warp Version 4, the location of this ®le is usually \mptn\etc\hosts.

±On Windows NT, the location of this ®le is usually <NT install path>\system32\drivers\etc\hosts.

You may use a Domain Name Server to avoid maintaining this ®le on multiple systems.

vThe locations of the equivalent ®les at the target DB2 Universal Database for OS/390 host.

vThe TCP/IP port number de®ned to DB2 Universal Database for OS/390. (Note that the associated service name information is not exchanged between the DB2 Connect workstation and DB2 Universal Database for OS/390). Port number 446 has been registered as the default for communication from a DB2 Connect workstation.

vThe TCP/IP addresses and hostnames for both the host and the DB2 Connect workstation.

vThe LOCATION NAME of the DB2 for OS/390 database server

vThe user ID and password to be used when issuing CONNECT requests for the database at the host.

Refer to your local network administrator and your DB2 for OS/390 administrator for help getting this information. Use one copy of the example work sheet, Table 3 on page 49, to plan each TCP/IP connection between DB2 Connect and a host database server.
