We are running on oracle 10.2.0.4 with windows 2008, now we are planning to upgrade to oracle 11.2
I have done oracle upgrade on standalone servers in past and every time I use to face problem with listner then i use to delete the listner and recreate it.
But this time I have to perform Oracle upgrade on windows 2008 cluster and also need to upgrade Oracle Fail Safe, well i have standard document form SAP on oracle upgrade, But still wondering if any one of you done this recently can share your document and experiences like what issues you guys faced and what are things i should take into consideration etc..
As its a production server and its 24/7 business and I am getting only 4 hours of downtime i don't want to take any chances, so i request you all to share your document and experiences with me and help please.
You can send document on my email id firstname.lastname@example.org
Thanks in advance
