You can change the brightness with an RGBImageFilter which converts the rgb values to HSV, increases the value, and converts back to rgb.

How to change SGA and PGA in 10g r2 RAC

Hi,
How to change SGA and PGA in 10g r2 RAC, its Linux.

Hi,
Here is the way i followed to change SGA and PGA in RAC.
Action Plan to change the memory parameter in the production environment(5/21/2010)
Note:
=====
Practice should be done in the DEV/TST environment before moving to Production;
Although the procedure could be applied in the testing environment the changing values
used in the testing environment should be modified since RAM number are not the
same between the testing servers and production servers.
1.     Make changes to these two parameters in one of
     the prod instance, e.g. PROD1
     ====================================================
     login as sysdba on sqlplus
Change :
alter system set sga_target=28G scope=spfile sid='*';
Change :
alter system set pga_aggregate_target=4G scope =spfile sid='*';
     sql>alter system set pga_aggregate_target=4G scope=both;
     sql>show parameter pga_aggregate_target;
          -- should see the altered number on both instances
Change:
sql>alter system set sga_max_size=28G scope=spfile sid='*';
sql>alter system set sga_max_size=28G scope=spfile ;
sql>alter system set sga_target=28G scope=spfile;
3.     shutdown database PROD (two instances should be shut down)
     $>srvctl stop database -d PROD
     $>. /$ORA_CRS_HOME/bin/crs_stat -- to check for the database status
4.     bring up database PROD (two instance should be brought up)
     $>srvctl START database -d PROD
     $>. /$ORA_CRS_HOME/bin/crs_stat -- to check for the database status
     login into both instances as sysdba to check
     sql>show parameter pga_aggregate_target
     sql>show parameter sga_max_size
          -- should see the altered number still there in both instances
          -- from step 1
     -- After confirming above two parameters are altered on both instances,
     -- then issue the syntax below in one instance
5)     check everything is ok

How to change sharing and permissions access on an Excel Version 14.4.3 (140616) file

I've created several Excel (from Office:Mac 2011) files on my MapPro; the are on the 'backup' drive (not the main drive). When accessing the 'get info' menu on the file, it shows that I can read and write; but if I open the file, the file name indicates it is read only, and attempts to save changes result in a message that requires a new name for the file. What can I do to change the read/write restriction so I can make changes without having to constantly rename the file with the changed information included?

Hello David,
Thank you for contacting Apple Support Communities.
The following articles explain how to change the permissions on files or folders. The first article is for Mavericks and the second for Mountain Lion.

How to change fonts and background in a finder window?

I have searched all over the system (10.5.4) and can't figure out how to change the font that displays the text in any finder window.
I know you used to be able to change the background of any finder window too.
I must be getting old!
Any ideas?

I don't think you can change the typeface (at least not with 3rd party hackies such as what Unsanity offers), but you can change the typeface size. With the Finder active click Cmd-J (View->Show View Options) and choose a different font size.
Hope this helps

How to change date and time format

Can i know how to change the date and time format?
I want the date format to be dd-mmm-yyyy and time format to be hh:mm:ss
These date and time is in my sapscript form.
I make use of PERFORM function in sapscript.
This is the code in my print program.
FORM get_actlog_QA TABLES in_tab STRUCTURE itcsy
                       out_tab STRUCTURE itcsy.
   DATA: object TYPE string, "
        qaname LIKE JCDS-USNAM, "NAME for engineering process, QA Manager
        qadate LIKE JCDS-UDATE, "DATE changed in engineering process, QA Manager
        qatime LIKE JCDS-UTIME. "TIME changed in engineering process, QA Manager
DATA: lt_jcds type standard table of jcds,
      wa_jcds like line of lt_jcds,
      new_date(10) type c.
READ TABLE in_tab INDEX 1.
MOVE in_tab-value TO object.
select * into CORRESPONDING FIELDS OF TABLE lt_jcds
from jcds WHERE objnr = object
    AND ( stat = 'E0005' )
    AND inact = ''.
Loop at lt_jcds into wa_jcds.
      qaname = wa_jcds-USNAM.
      qadate = wa_jcds-UDATE.
      qatime = wa_jcds-UTIME.
   READ TABLE out_tab INDEX 1.
   MOVE qaname TO out_tab-value.
   MODIFY out_tab INDEX sy-tabix.
   READ TABLE out_tab INDEX 2.
   MOVE qadate TO out_tab-value.
   MODIFY out_tab INDEX sy-tabix.
   READ TABLE out_tab INDEX 3.
   MOVE qatime TO out_tab-value.
   MODIFY out_tab INDEX sy-tabix.
endloop.
clear wa_jcds.
ENDFORM.
This is my PERFORM in sapscript.

Sapscript
Prepared by : &V_QANAME& ,, &V_QADATE& ,, &V_QATIME&
The output now is
Prepared by: Name   20080312 115536
I want to change the date format to 12-MAR-2008
and the time format to 11:55:36
Can anyone please suggest on how to solve this?
Thank you.

Hi,
Before assigning the QADATE value you can write the logic to display 20080312   as 12-MAR-2008 taking the offset values .
Like
qadate = wa_jcds-UDATE.
qatime = wa_jcds-UTIME.
lw_year    = qadate(4).
lw_month = qadate+4(2).
lw_date    = qadate+6(2).
case lw_month.
when 1.
when 2.
        concatenate lw_date '-FEB-' lw_year into qadate.
when 3.
      concatenate lw_date '-MAR-' lw_year into qadate.
endcase.
READ TABLE out_tab INDEX 2.
MOVE qadate TO out_tab-value.
MODIFY out_tab INDEX sy-tabix.
And you can also change the timeformat also .
then assign that value to qatime .Then
READ TABLE out_tab INDEX 3.
MOVE qatime TO out_tab-value.
MODIFY out_tab INDEX sy-tabix.
I think this helps you.
Regards,
Rajitha.

How to Change date and time on my printer

I want to know how to change the date and time on my printer.

annazmussaqib,
OK, now enter the following command in the administrative user’s Terminal window:
sudo date -n 122921502013
When it asks you for a password, enter your administrative user’s password; it will not show the password as you type it.
After you enter that command, enter this command again:
date
It should show a date and time that is close enough to the actual date and time that you should be able to go into the Date & Time pane of System Preferences without it hanging.

Is it possible to do so? In addition, will the Image Mode such as RGB, CYMK or Grayscale be effecting such solution?
Thanks in advance.

These are NOT dropdown menus. They are dropdown LISTS.

And from the links in the Google search you can learn that a list item has no style.
And a dropdown list behaves differently from dropdown menus. Here's how it looks on Mobile Safari :
