Defining the transactions that issue type-1 AO commands

You need to define the transactions that are allowed to issue type-1 AO commands. You can do this using the AOI= parameter in the TRANSACT macro.

The AOI= parameter also allows you to specify the user ID used for security checking when you use RACF®, DFSCCMD0, or both as your security facility. You can use any of the following identifiers as a user ID:

• The user ID of the user signed on at the terminal issuing the transaction
• The transaction code
• The first three letters of the commands name
