Upgrade and patches........

Hi there, I'm running informix Dynamic online server ver7.2 and 4gl and a sun solaris 2.5.1. I'm trying to fine out what patches, from Sun, Informix recommends to apply? My vendor tells me that the system they supplied six months ago was current, while I don't disagree with that statement, I'm not sure if they know, what patches are safe to apply. Does informix have an approved list of patches,from Sun for the solaris 2.5.1, that they have tested with the Dynamic online server (which we just upgraded to the latest version)? Thanks for the help Pat Militzer pmilitzer@ultracom.com
