Determine whether you intend to use secured or non-secured DDM connections to the Nodes in the Enterprise Network. In order to use a non-secured DDM connection, the user profile must exist on the Node, although the user's password will not be validated. To use a secured DDM connection the user profile and password must be the same on both the Hub and the Node. You may want to review this setup with your site security administrator before taking specific actions.

Use the one of the following commands to change the TCP/IP DDM attributes for non-secured operations:
CHGDDMTCPA PWDRQD(*NO)CHGDDMTCPA PWDRQD(*USRID)
If you are going from a secured DDM connection to a non-secured DDM connection make sure to remove the server authentication entries. Use the following commands to remove server authentication entries for each user profile:
RMVSVRAUTE USRPRF(user-profile) SERVER(QDDMSERVER)RMVSVRAUTE USRPRF(user-profile) SERVER(QDDMDRDASERVER)
NOTE: "QDDMSERVER" and "QDDMDRDASERVER" must be uppercase.
Go to step 3.
For Secured DDM connection
Use one of the following commands to change the TCP/IP DDM attributes for secured operations:
...
There can only be one server authorization entry for a user no matter what remote system is specified. This means that for a user to access multiple Nodes in the Enterprise Network, that user profiles and passwords must be the same on all Enterprise Networked Nodes.
Do not use user profile QBRMS for the Node user profile. Create a new user profile and specify user profile QBRMS for the Group profile (GRPPRF) parameter of the user profile on the Node. Use this new user profile on the Node for the User ID (USRID) parameter of the Add Server Authentication Entry (
ADDSVRAUTE) command.
Go to step 3.
For Non-secured DDM connections
Use the one of the following commands to change the TCP/IP DDM attributes for non-secured operations:
CHGDDMTCPA PWDRQD(*NO)CHGDDMTCPA PWDRQD(*USRID)
If you are going from a secured DDM connection to a non-secured DDM connection make sure to remove the server authentication entries. Use the following commands to remove server authentication entries for each user profile:
RMVSVRAUTE USRPRF(user-profile) SERVER(QDDMSERVER)RMVSVRAUTE USRPRF(user-profile) SERVER(QDDMDRDASERVER)
NOTE: "QDDMSERVER" and "QDDMDRDASERVER" must be uppercase.
