Information About NLS

[sryarraguntla]

Hi Everyone,

I have installed datastage vesrion 8.0.1 on windows test server 2003. I also enabled NLS while installing. Now my question is Do i need to install NLS? would there be any problem in future as i enabled NLS.Does installing NLS makes any difference?

How can i uninstall NLS?


Thanks

There are two questions: installed and enabled. If you have installed NLS but do not wish to use it, set NLSMODE in uvconfig to 0 and regenerate. This will disable NLS. The only cost will then be the small amount of disk space taken up by the NLS maps.

You can not uninstall NLS. You can only uninstall the whole of DataStage, then re-install without NLS.

Thanks Ray for your reply.

Setting NLS mode to 0 : I have searched the UVconfig file in c:\IBM\InformationServer\Server\DSEngine. I found

# NLSMODE - Set to 1 if NLS mode is ON for the
# system as a whole. 0 means that NLS mode is OFF.
NLSMODE 1


Do i need to change the above NLSMODE 1 to NLSMODE 0.And may i know how to regenerate .
could you please tell me how to do.


# NLSREADELSE - Set to 1 if READs that fail to map
# all characters in a record are to take the ELSE
# clause. 0 means that unmappable characters are
# returned as the Unicode "replacement" character,
# 0xFFFD.
NLSREADELSE 1

# NLSWRITEELSE - Set to 1 if WRITEs that fail to map
# all characters in a record are to abort (or take
# the ON ERROR clause if present). 0 means that
# unmappable characters are converted to the file
# map's "unknown" character (for example "?") before
# writing the record, and information may therefore
# be lost.

# NLSLCMODE - Set to 1 if NLS locale support is ON

None of the other NLS parameters has any effect if NLSMODE is 0.

Search for "uvregen" or "uv -admin -regen" either here or in your DataStage manuals.
