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:
- Log on again with a new user ID that has ACCOUNT authority
- 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:
- After creating the UADS, log off.
- Log on with a new user ID that has ACCOUNT authority.
- 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.
