How to create an Oracle stored procedure to lock user accounts not logged onto database for more than 90 days

Question

How do I create an Oracle Stored Procedure to lock user accounts that's not logged onto the database for more than 90 days?

I assumed that I could create a Profile Object and list the Resource Parameters in my database but I am using Oracle 11g and it appears that feature doesn't exist.

This is what I tried so far:

select username from dba_audit_trail
where  action_name = 'LOGON'
group  by username
having max(timestamp) < sysdate - 90

I also attempted to create a profile attempting to use INACTIVE_ACCOUNT_TIME as my Resource Parameters but it does not exist in Oracle 11g:

CREATE PROFILE time_limit LIMIT 
INACTIVE_ACCOUNT_TIME 90;

For 12c it can be:

begin
for x in 
(select username
  from dba_users
  where last_login < sysdate - 90) 
loop
  execute immediate 'alter user ' || x.username || ' account lock';
end loop;
end;

If you're using 11g you may try your query for loop:

begin
for x in 
(select username from dba_audit_trail
 where  action_name = 'LOGON'
 group  by username
 having max(timestamp) < sysdate - 90) 
loop
  execute immediate 'alter user ' || x.username || ' account lock';
end loop;
end;
