Online notes are available from the IBM Informix Library at http://www.ibm.com/software/data/informix/pubs/library/ and in the IBM Informix Information Center at http://publib.boulder.ibm.com/infocenter/ids9help/index.jsp. Additionally you can locate these files before or after installation as described below.
Before Installation
All online notes are located in the /doc directory of the product CD. The easiest way to access the documentation notes, the release notes, and the fixed and known defects file is through the hyperlinks from the TOC notes file.
The machine notes file and the fixed and known defects file are only provided in text format.
After Installation
On UNIX platforms in the default locale, the documentation notes, release notes, and machine notes files appear under the $INFORMIXDIR/release/en_us/0333 directory.
