Creating from a terminal

To create the UADS and the broadcast data set from a terminal, add a LOGON procedure named IKJACCNT to the procedure library. During system installation, one user ID (IBMUSER) is copied into the newly-created UADS. IBMUSER is authorized to use one LOGON procedure, IKJACCNT. A sample IKJACCNT LOGON procedure, which is also in IP01.PROCLIB for ServerPac users, follows.

//IKJACCNT  EXEC   PGM=IKJEFT01,DYNAMNBR=10
//SYSUADS   DD     DSN=SYS1.UADS
//SYSLBC    DD     DSN=SYS1.BRODCAST

Perform the following steps:

Activate VTAM®.
Log on using the following command:
```
logon ibmuser nonotices nomail
```
The keywords NONOTICES and NOMAIL are needed to prevent the LOGON processor from accessing the broadcast data set before the data set is formatted.
Enter the ACCOUNT command and issue the SYNC subcommand to format a skeleton of the broadcast data set.
Issue ADD subcommands to add the new user IDs to both the UADS and the broadcast data set.
For security reasons, you may want to delete the IBMUSER user ID. To delete IBMUSER, perform the following steps:
1. Log on again with a new user ID that has ACCOUNT authority
2. Enter the ACCOUNT command and issue the DELETE subcommand to delete the IBMUSER user ID.
  Note: If you plan to install a security server (for example, RACF®) that requires the use of IBMUSER for installation, do not delete IBMUSER. Instead, perform the following steps:
  1. After creating the UADS, log off.
  2. Log on with a new user ID that has ACCOUNT authority.
  3. Issue the ACCOUNT command followed by the ADD subcommand. Add a password and any necessary items, such as account number and procedure name for the IBMUSER user ID.
