Oracle 10g is a good database product, and it\u2019s stood many of my clients in good stead for several years now. Even though Oracle 11g has been out on the market for a while now, I\u2019m not seeing it widely adopted yet, which I find interesting.<\/p>\n
I see three common factors feeding into that decision: First, satisfaction with 10g \u2013 10g databases are chugging along just fine in most shops. Second, risk aversion \u2013 why take the risk of upgrading to a newer version, especially if 10g is still running fine? Third, cost \u2013 the economic and opportunity cost of upgrading might seem too high: why pay a consultant to do the upgrade or pull a staff member away from other productive work? A less common reason I hear is that a software vendor has not yet certified their application with 11g.<\/p>\n
But 10gR2 (Release 2) is about to enter the first phase of de-support, and 10gR1 is already well into the de-support process. It\u2019s time to start thinking about moving onto 11g. It has some interesting new features, and running a currently supported version also will put you in good standing with Oracle Technical Support. Plus, eventually, most software vendors will not support their product if it\u2019s running on an out-of-date database version.<\/p>\n
