Hi, 
  Sorry I am not an informix dba, and I was faced to copy a
sub-database(sorry I don't know the clear name of such concept, as
informix is like sql-server, which used multiple database) from one
informix database system to another informix database.
   I know in oracle, we can use transportable tablespace, copy the
datafile and transport the metadata, and do something else. How can I
do it in informix then? Is there document which talk about the detail
step?

Thanks

It would really help if you knew the versions of the Informix databases.

Assuming Informix IDS 7.x or IDS 9.x
If the two systems are binary compatible the fastest method is to use 
onunload/onload. If the systems are not binary compatible the easiest 
way is to use dbexport/dbimport.

Everything is well documented in the manual "IBM Informix Migration 
Guide". This manual covers all Informix databases from Standard Engine 
and Online to IDS and XPS. See http://www.ibm.com/informix/pubs

Don't forget HPL.
