Plz let me know how to do this ?

Thanks,

Try auditing create,drop and audit user stmt

AUDIT CREATE USER
AUDIT ALTER USER
AUDIT DROP USER

or you can execute

AUDIT CREATE USER BY ACCESS WHENEVER SUCCESSFUL
AUDIT CREATE USER BY ACCESS WHENEVER NOT SUCCESSFUL

OR

AUDIT CREATE USER BY SESSION

Are you suspicious of administrators or normal users?
Which parameter(s) did you enable?...
1.AUDIT_SYS_OPERATIONS=TRUE
2.AUDIT_TRAIL=DB/OS
3.GOTO
