Change user locale in AIX - utf-8

Question

Good day,
In one of my AIX server, let say server 1, I login as db2inst1, and enter command locale, then I get this:
bash-4.3$ locale
LANG=en_US.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_ALL=en_US.UTF-8
And in my another AIX server, let say server 2, I login as db2inst1, and enter command locale, then I get this:
bash-4.3$ locale
LANG=EN_US.UTF-8
LC_COLLATE="en_US"
LC_CTYPE="en_US"
LC_MONETARY="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_MESSAGES="en_US"
LC_ALL=en_US
I would like to change the value of "en_US" to "en_US.UTF-8". So, I login as root, then go to smitty -> System Environments -> Manage Language Environment
-> Set User Languages, follow by key in the username db2inst1, but I cant see anything that allow me to changed to "en_US.UTF-8".
I am suspecting I am doing in the wrong way. Trying to google but still cant get the correct way to do it. Kindly advise.

Answer 1

I found the solution.
Go to ~/.profile
update this value:
export LC_ALL=en_US.UTF-8
and save.

Answer 2

You need to install EN_US on server 2. Extra locales are inside the AIX install CD. So insert the CD into CD-ROM at first.
root#aix6:/$ smit mlang
->Change/Show Primary Language Environment #Press Enter
---->Change/show Cultural Convention, Language, or Keyboard #Press Enter
---->Primary CULTURAL convention #Press F4, move cursor to "UTF-8 English (United States) [EN_US]", press Enter
---->Primary LANGUAGE translation #Press F4, move cursor to "UTF-8 English (United States) [EN_US]", press Enter
---->Primary Keyboard #Press F4, move cursor to "UTF-8 English(POSIX) KBD ID 103P [EN_US]", press Enter
This will install X11.loc.EN_US.bash.rte, bos.msg.EN_US.rte etc. and set the system locale to EN_US. Relogin to see the locale change.
root#aix6:/$ locale charmap
