How-to: Clone Raspberry Pi SD Card

1. Open the application Win32DiskImager (probably you have used it during the first installation)
   
   
2. In the "Image File" textbox, enter the path of the image file. For example, I put c:\temp\clone_raspberry_20131115.img
3. In the "Device" combobox, select the letter of your SD card reader.
4. Click the "Read" button to create the image file from your card.

Enjoy it!

Who users are connected or login to Oracle applications?

It give the number of session users on the system in the past 1 hour:

select "is".user_id, user_name, description, email_address,  to_char(min(first_connect) ,  'DD-MON-YYYY HH24:MI:SS') min_first_connect, to_char(max(last_connect),'DD-MON-YYYY HH24:MI:SS') max_last_connect,count(*) "# sessions"

from apps.icx_sessions "is"

inner join apps.fnd_user fu on fu.user_id = "is".user_id

where  last_connect > sysdate - 1/24 and "is".user_id != '-1'

group by "is".user_id, user_name, description, email_address;

This return the user login into system with at least a session and a process:

select d.user_id, d.user_name, d.description, d.email_address, a.terminal_id, b.machine, to_char(a.start_time,  'DD-MON-YYYY HH24:MI:SS') start_time

from apps.fnd_logins a,

v$session b, v$process c, apps.fnd_user d

where b.paddr = c.addr

and a.pid=c.pid

and a.spid = b.process

and d.user_id = a.user_id

and (d.user_name = 'USER_NAME' OR 1=1);

Enjoy it!
