Upgrades & Opportunities with the Arrival of 12cR2

    By: Michelle Malcher on Dec 22, 2016

    For all those waiting for Oracle database 12c Release 2, it is time! 12cR2 has been showcased and is already available in the public cloud, which means it is time to start planning those upgrades. This release brings new features and provides the stability over the R1 version. The structural changes to 12c, with container and pluggable databases, can cause reasons for concern about the upgrades. The user community has been involved in beta testing and still more are early adopters of 12cR1. This is a great opportunity to learn from the community.

    It is also not just the database that continues to have new releases, but the tools we use for managing them. Oracle Cloud Control updates include features to provision databases and manage the large hybrid and cloud environments that we are dealing with. Big Data, clustered databases and managing tools all have enhancements and new features – new features that are becoming must haves for the applications and data services to perform well, be secure and highly available.

    I always view upgrades as an opportunity for new features to benefit the system and provide a solution for a current issue or project needs. These benefits do help justify the required testing, maintenance windows and effort for the upgrades. However, just as there have been enhancements to providing always-available databases, there are tools and steps to minimize the database downtime and maintenance windows for upgrading.

    As with any database upgrade, standards and baselines should be reviewed to validate that proper security and feature changes for the database to meet your company’s minimum requirements. For example, the non-container database is being deprecated so the standard build would now be a container database with one pluggable.

    In Q4 2016, SELECT brings you other upgrade processes and testing plans. Gary Gordhamer provides a DBA 201 article on risk and testing database upgrades. Jim Czuprynski continues his series on Real Application Testing features. Donna Zehl informs us on how to use replication to minimize the downtime during migration to database 12c. These articles, along with others, should provide steps and valuable information to help prepare for the new releases. In upcoming SELECT articles, we will continue to examine the new 12cR2 database features and where the value is being added.

    Successful upgrades and using the new technology features are definitely in store for those in the community. As always, reach out to us with your questions, comments, or let us know about your favorite new feature in Oracle database 12c at select@ioug.org.
