Hi Michael, We're running databases on both 11.11 and 11.23. The only issue I've run into was with the 9.2.0.6 patch install; the system check only permits 11.11. Metalink note Note:294682.1 suggests updating the oraparm.ini file to add 11.23, which worked just fine. I think I remember hitting this on early 10g installs too, but I am not quite certain on that. I can't help with the Informatica question; we're not running that one and it appears to be the bigger issue.
