Controlling LU attachments to the network

VTAM® checks to prevent an unauthorized logical unit (LU) from attaching to the network and presenting itself to other LUs as an acceptable partner in communication. It requires each LU that attaches to the network to identify itself by a password.

About this task

If that requirement is in effect for your network, your Db2 subsystem, like every other LU on the network, must:

1. Choose a VTAM password.
2. Code the password with the PRTCT parameter of the VTAM APPL statement, when you define your Db2 to VTAM.
