play with vncserver... when it showed nothing

I often use "ssvnc" to connect my servers to install or do something about X. Anyway, I must to start VNC before by using "vncserver".

[surachart@oralearning ~]$ vncserver

New 'oralearning:1 (surachart)' desktop is oralearning:1

Starting applications specified in /home/surachart/.vnc/xstartup
Log file is /home/surachart/.vnc/oralearning:1.log

[surachart@oralearning ~]$

I ended up find nothing when I connected VNC as below picture.

So, I checked "/home/surachart/.vnc/oralearning:1.log" file to investigate the issue.

Fri May 17 15:46:12 2013
 vncext:      VNC extension running!
 vncext:      Listening for VNC connections on all interface(s), port 5901

/home/surachart/.vnc/xstartup: line 29: twm: command not found
/home/surachart/.vnc/xstartup: line 28: xterm: command not found

As messages in log file. I installed some packages, killed VNC and started VNC again.

The account is locked on APEX

I have used APEX 4.2.2. I was unable to logon my APEX with INTERNAL workspace as admin. It showed "The account is locked".

What was I able to do? ... run "apxchpwd.sql" script. I didn't think so. After checking in "apxchpwd.sql" script.
So, I checked in "wwv_flow_fnd_user_api" package, I found wwv_flow_fnd_user_api.UNLOCK_ACCOUNT procedure.

PROCEDURE UNLOCK_ACCOUNT
 Argument Name                  Type                    In/Out Default?
 ------------------------------ ----------------------- ------ --------
 P_USER_NAME                    VARCHAR2                IN

I thought I should test it. First of all, I must to make sure "security_group_id"(It should be number 10).

SQL> SELECT workspace_id FROM apex_workspaces WHERE workspace = 'INTERNAL';

WORKSPACE_ID
------------
          10

Tested to unlock "admin" user on "INTERNAL" workspace.

SQL> alter session set current_schema = APEX_040200;

Session altered.

SQL> begin

    wwv_flow_security.g_security_group_id := 10;
    wwv_flow_fnd_user_api.UNLOCK_ACCOUNT('ADMIN');
    commit;

end;
/

PL/SQL procedure successfully completed.

then I tested login again... It works for me. ^______________^
