Don't let this thread die ...
Dumping few details.
You have some informx procedure that you want to call/execute from Oracle. Oracle will not identify your informix procedure.
So come out of oracle environment.
You need to execute this from your OS - unix.
You will need some unix shell script that will call informix procedure.
And then you'll have to "plug" this script to Oracle - you will have to make oracle call this shell script.
Some script similar to following oracle pseudo code. You will need some informix version of this ....
