add a new language to Oracle

I first thought of adding Klingon. Well, finally I added Romansh, which is the fourth official language in my country.

Ok, here we go :

$ $ORACLE_HOME/nls/lbuilder/lbuilder &

The Oracle Locale Builder tool is started.

File –> New… –> Language

You specify the language, the spelling for January, for Monday, etc… Most fields are mandatory. If you do not know about one field, like EBCDIC, just find one in the “Show existing definition…” Dialog

File –> Save as…

You save your nlt file

File –> Tools –> Generate NLB

Three NLB files are generated.

$ ls -l *.nl*
-rw-r--r-- 1 lsc users   934 2008-02-19 18:17 lx003eb.nlb
-rw-r--r-- 1 lsc users  3843 2008-02-19 18:17 lx003eb.nlt
-rw-r--r-- 1 lsc users   128 2008-02-19 18:17 lx0boot.nlb
-rw-r--r-- 1 lsc users   428 2008-02-19 18:17 lx0boot.nlt
-rw-r--r-- 1 lsc users 22528 2008-02-19 18:17 lx1boot.nlb

Copy all your the NLB files to your ORACLE_HOME/data/nls.

Restart your instance.

Let’s test it 😉
