Wow, that's really going back. I don't really know, but I would guess that HACMP is supposed to restart the instance but not the listener. I don't have experience with 9i on AIX, but on Linux and Windows Oracle provided a bare-bones cluster framework. My understanding was that they relied mainly on HACMP for AIX. If my memory serves me well, the 9i linux clusterware did restart the instance but did not restart the listener - hence my guess. But you probably know more than I do about this. :) I'm sure there are others lurking on the list who are still maintaining 9iRAC/AIX systems... hopefully you'll get a good answer! -Jeremy -- Jeremy Schneider Pythian Consulting Group Chicago +1 312-725-9249 http://www.pythian.com On 09/10/2012 07:52 AM, Ls Cheng wrote: > Hi all > My experience with RAC 9i is limited and almost cero wrunning this in AIX > HACMP. > > Does anyone know when instance crashes or listener dies for any reason do > they get restarted by AIX HACMP? > > Thanks > > -- > LSC > > > -- > //www.freelists.org/webpage/oracle-l > > > -- //www.freelists.org/webpage/oracle-l
