I think there is a case to be made for improving the installation model. The current model originated when the engine was bundled with ISQL or I4GL; there wasn't any OnLine product, and SE didn't exist as an identifiable product. However, I posted a month or two ago the tools necessary to allow you to install new Tools products without overwriting the Engines. It isn't a direct installation, but you can't get everything via the back door... I posted ixremove, ixcreate, cpinfxdir, etc. If I was faced with the existing installation: /usr/informix/7.13.UC1 OnLine 7.13.UC1 ESQL/C 7.13.UC1 I4GL 6.03.UC1 I4GL-RDS 6.03.UC1 I4GL-ID 6.03.UC1 ISQL 6.03.UC1 and if I then got a new distribution of ISQL and I4GL (6.04.UC1), then what I would do is (in outline): * create a temporary directory for the new software * install the new software in the temporary directory * uninstall the old software from the existing, main INFORMIXDIR * selectively copy the new software to the main INFORMIXDIR * unselectively delete whatever is left in the temporary directory In fairly complete detail: su root mkdir /usr/informix/6.04.UC1 cd /usr/informix/6.04.UC1 export INFORMIXDIR=$PWD # Korn Shell! # Use INFORMIXDIR=`pwd`; export INFORMIXDIR in Bourne Shell, # and change to Korn Shell if you use C Shell. tar xvf /dev/rmt/0m # Or whatever... # NB: the keys I'm using aren't valid. ./installsql <<! ABC#D123456 ZZZZZZ ! tar xvf /dev/rmt/0m ./install4gl <<! ABC#D123457 ZZZZZA ! # Repeat for I4GL-RDS (install4gp) and I4GL-ID (install4db) # Check what will be removed from the main INFORMIXDIR TOOLSFILES="-F fglfiles -F fgpfiles -F sqlfiles -F fgldbfiles" ixremove -I /usr/informix/7.13.UC1 -vn $TOOLSFILES # Remove it ixremove -I /usr/informix/7.13.UC1 $TOOLSFILES # Selectively copy the new software into the main INFORMIXDIR # -c = copy (not symlink) # -d = include demo software # -v = verbose ixcreate -cdv -R /usr/informix/6.04.UC1 -L /usr/informix/7.13.UC1 $TOOLSFILES # Unselectively clean up the temporary directory cd / rm -fr /usr/informix/6.04.UC1 The only other thing you'd have to check on is that any symlinks in /usr/lib which pointed to /usr/informix/6.04.UC1 were remade point to /usr/informix/7.13.UC1.
