Choosing a password for the local subsystem
Choosing a VTAM® password is optional. Db2 does not require you to use a password as long as you have not included one in the VTAM APPL statement.
Procedure
To set a local subsystem password:
Enter the password by using the PRTCT option of the VTAM APPL statement. The password
can have from one to eight EBCDIC characters.
This password is not transmitted through the network, so there is no need to share the password with the other systems.
