Oracle 12g RAC and Grid Infrastructure Strategy Review

Before you plan your migration to 12c RAC and Grid Infrastructure, ensure that the implementation strategy decided upon is appropriate for your organization's present and future needs.

Oracle 12g Grid Infrastructure (Clusterware, Flex ASM and the ASM Cluster File System) combined with Real Application Clusters provide amazing scalability, stability and flexibility for Enterprise database management. However, it also introduces new concepts, complexities and a possible paradigm shift for an organizations DBA's and System/Storage Administrators.

This poses new questions. Grid Infrastructure is comprised of many components - which are best for your organizations current and future needs? Whereas in the past, the DBA and System Admin roles where clearly defined and delineated; how - and who - will manage storage for your Oracle databases?

SkillBuilders' Oracle Certified Master DBA John Watson will work with your management and key technical personnel to answer these questions.

Your organization's personnel will

  • Gain an appreciation of the major Grid Infrastructure facilities

  • Gain the knowledge required to make informed decisions regarding how Clusterware, ACFS, and RAC - and the key components of each - should be used. This will ensure that the implementation strategy decided upon is appropriate for present and future needs.
  • Help the organization decide how the separation of job roles (e.g. system administrator vs DBA) will best be handled in their organization given the new integrated architecture presented by Oracle Grid Infrastructure (i.e. Oracle Clusterware and ASM Cluster File System).
  • Help define the training requirements for Oracle Database Administrators and System and Storage Administrators.

The lectures and discussions will be technical and will assume knowledge of Oracle database and instance architecture. If available environments permit, possibly a few demos but generally chalk-and-talk.


  1. The SA (System Admin) domain and the DBA (DB Admin) domain

    Grid infrastructure includes facilities for managing IT components that traditionally have been within the SA domain: storage, networking, and clusterware. A decision needs to be made on whether responsibility for these components should lie with SA staff, DBA staff, or both.

  2. Which GI components should be implemented?

    Implementing the Grid Plug and Play functionality is potentially very useful, but not all sites choose to use it. A decision needs to be made early in the project on whether to implement GPnP. It would not be easy to change the decision later.

  3. Policy managed databases

    Policy management allows the clusterware to determine where instances should run, automating the distribution of resources across available nodes. Again, a decision needs to be made early on whether to implement this.

  4. The database listening architecture

    Whatever decisions are made in 1 through 3 above, the 12c (actually 11.2 and up) listener model is very different from earlier releases. An appreciation of this is necessary to inform the design of the cluster(s).

  5. Storage technologies

    Various technologies are usable as database storage, such as clustered file systems, SAN, NFS, and iSCSI. Grid Infrastructure can replace or work in harmony with facilities such as third party clustered files systems and file servers for non-database applications. There may be significant cost and functionality implications that need to be considered.

  6. High availability

    Oracle's HA architecture consists of one or more of RAC, Data Guard, ACFS, RMAN, Streams (and other products) working together. Network, SAN, and operating system technologies are also relevant. All of these need to be considered together when deciding how to meet whatever service levels are required.
