Now that Oracle premier support has ended for the 11gR2 release of the Database, Oracle database users should be thinking about the move to 12c. This blog gives a quick example as to why you should be at least thinking about the planning of the upgrade sooner rather than later.
Oracle 11.2 RDMS fell out of premier support at the end of January 2015, starting its three year tenure in Oracle extended support. As has been the trend in later releases of Oracle software, Oracle have waivered the cost of the extended support up until the end of January 2016.
The first point to remember about extended support is that it only covers the terminal release of the software i.e. 220.127.116.11, therefore at the very least you should be planning to patch to this level to ensure you are getting the benefit of the extended support.
But what happens post January 2016? Let’s take a typical Oracle configuration as an example
(Pricing based on 2014 UK price list and applying standard Oracle discounts)
To maintain extended support for the remaining 2 years that it is available for 11gR2, you would incur an additional expense of nearly £33,000. This is based on Oracle’s current pricing for extended support for years 2 & 3. That’s a significant amount of money to pay for a product that is nearly six years old. Clearly the example above is relatively simple, if as a customer you are using additional database options or have a larger estate than the example, the additional costs are far greater.
Many Oracle customers have an edict that states they will only move to the second release of a software product and then usually only after the first patch set has been released. If this mantra stays in place for 12c, based on Oracle’s current development timescales it’s very likely that an upgrade to 12.2 will not be able to take place until well into the 3rd year of 11gr2 extended support. By that time the extended support fees will have been spent.
A more pragmatic approach would be to look at the 18.104.22.168 release of 12c which could be considered as the second release of the 12c software as it contains new features as well as bug fixes for the base release. This release has already been available for over 6 months so there shouldn’t be any question over its stability.
Whilst the benefits of the new features of Oracle 12c have been covered in many other blog entries and our very own 12c Seminars and webinars, to help build a business case for a 12c Migration, this hidden financial impact of not moving to 12c within the next 9 months should also be brought to the forefront.
Understandably many IT departments will be working under operational pressures and way not have the window of opportunity to look at planning for 12c. As recognised experts in this field, e-DBA can assist in 12c readiness and indeed perform the upgrade process in its entirety in order to alleviate any pressure IT departments may find themselves under to perform this migration.
Once migrated, the database environment will once again be back in premier support coverage for another 3-4 years thus mitigating any additional operational risk and without incurring any additional support costs.
