Abstract

This technical document explains how to configure your AS/400 to accept DRDA requesters, such as StarSQL, over TCP/IP.

Solution

To configure the DDM TCP/IP server:

  1. Logon to your AS/400.
  2. Change the DDM TCP/IP Attributes to autostart using the command:

    CHGDDMTCPA AUTOSTART(*YES)

  3. Start TCPIP DDM Server using the command:

    STRTCPSVR SERVER(*DDM)

To verify which port your AS/400 is listening for remote DRDA requests:

  1. Logon to your AS/400.
  2. Work with service table entries using this command:

    WRKSRVTBLE

  3. Look for the DRDA entry with the port number 446.

Or, you can also use the following commands:

  1. Work with TCPIP status using the command:

    WRKTCPSTS

  2. Choose option 3, "Work with TCP/IP connection status".
  3. Find the entry with port "drda" and press "F14=Display port numbers".
