| Installing Locally | You can download Informix Dynamic Server Express Edition 11.5 Trial for Linux and Windows. |
| Database Client | There's a [[https://www14.software.ibm.com/webapp/download/search.jsp?rs=ifxdl|database client SDK]] available, which might be of use. I couldn't get the demo client working.
I used [[http://squirrel-sql.sourceforge.net/|SQuirreL SQL Client Version 2.6.8]] after installing the [[https://www14.software.ibm.com/webapp/download/search.jsp?go=y&rs=ifxjdbc|Informix JDBC drivers]] ("emerge dev-java/jdbc-informix" on Gentoo).

| Logging in from command line | If you get local admin rights on a Windows box and have a GUI logon:
- Click: Start | All Programs | IBM Informix Dynamic Server 11.50 | someservername. This will give you a command prompt with various Environment variables set properly.
- Run dbaccess.exe from your command prompt. This will bring up a text-based GUI that allows you to browse databases.
The following were set on my test system. This may help if you get command line access, but can't get a GUI - you'll need to change "testservername":
set INFORMIXDIR=C:\PROGRA~1\IBM\IBMINF~1\11.50
set INFORMIXSERVER=testservername
set ONCONFIG=ONCONFIG.testservername
set PATH=C:\PROGRA~1\IBM\IBMINF~1\11.50\bin;C:\WINDOWS\system32;C:\WINDOWS;

| Identifying on the network | My default installation listened on two TCP ports: 9088 and 9099. When I created a new "server name", this listened on 1526/TCP by default. Nmap 4.76 didn't identify these ports as Informix:
$ sudo nmap -sS -sV 10.0.0.1 -p- -v --version-all
...
1526/tcp open pdap-np?
9088/tcp open unknown
9089/tcp open unknown
...
TODO How would we identify Informix listening on the network?
