Entering RACF TSO commands in the foreground

To enter RACF® TSO commands in the foreground, you must be able to:

Conduct a TSO terminal session
Use the TSO commands
Use system-provided aids (HELP command, attention interrupt, conversational messages)
Respond to TSO prompts

See z/OS TSO/E Primer and z/OS TSO/E Command Reference for any information you need.

In addition, to enter RACF TSO commands from the foreground, you must be defined to the system.

The TSO LOGON command is used to define you to the system as a RACF user through the user identity (user ID), password, GROUP, and OIDCARD operands. To change your RACF password, use the new_password option on the LOGON command. If you have more than one account number defined in your TSO profile, you must supply an account number on the LOGON command.

The default data set name prefix in your TSO profile is used as the high-level qualifier of a DASD or tape data set name if you do not enter the fully qualified name in a TSO or RACF command. RACF also uses the TSO default prefix as the high-level qualifier for the name of a CLIST created as a result of the RACF SEARCH command. If you do not have a prefix specified in your TSO profile, (PROFILE NOPREFIX), the user ID from the SEARCH command issuer's ACEE is used as the qualifying prefix.

If you frequently use RACF TSO commands on RACF-protected data sets, you can set your TSO default prefix as follows:

Set the default prefix to your user ID if you do a good deal of work with your own data sets.
Set the default prefix to a specific RACF group name if you are working mostly with data sets from that group.

Although, the command examples in this document generally use uppercase characters, you can enter commands using either uppercase or lowercase characters.
