Slide Goal: To provide a virtual demonstration of the product in action.
SLIDE IS ANIMATED
Modern application performance is made up of several interlocking pieces that span the technology stack. Much effort has been focused on delivering and deploying an application. However, this is not ultimately what an end-user sees. The end-user experience is defined by the runtime performance of an application. While many tools allow for monitoring an application’s this, it is not enough. What is required is Active runtime quality of service management that can both identify bottlenecks and adjust resources to ensure the most important applications maintain their required levels across ever-changing demand.
Here we have an RTI datacenter with 3-tier and 2-tier systems operating within their response time objectives. We have 3 Pools in each of the top three tiers and a common storage pool for a total of 10 managed pools.
<CLICK> Demand for the EMEA Sales application rises the SLO is violated.
2. <CLICK> The QoS system compensates by adjusting a resource such as CPU shares while still meeting objectives.
3. <CLICK>Suddenly our most important DB server pool goes red for all Sales apps.
4. <CLICK>Resources, such as a server, are reallocated from our least important DB server group to restore performance
We are instrumenting the entire Oracle stack to enable us to provide true QoS management thereby allowing you in the end to effectively run your applications on “cruise control”.
Alert: Disk space low – Add more storage.
Action: Storage added – rebalancing started.

10. ASM Dynamic Volume Manager
New general purpose volume platform
Supports ACFS and 3rd party file systems
Eliminates the need for 3rd party VMgrs
New ASM volume management service
Cluster and single host volumes
Loadable kernel driver
‘Dynamic Volume’ is an ASM file
+DATA/volume1  /dev/asm/volume1-123
Leverages ASM features
Easy on line provisioning
Cross platform (Linux, Windows, UNIX)
Managed using ASMCMD, EM and SQL OS
/dev/asm/volume1-123
ASM DG
+DATA/volume1
The ASM Dynamic Volume Manager is a kernel loadable device driver and services that provides volume management services and a standard device driver (ASM device driver (AVD)) interface to clients (i.e. ACFS). File systems or other user processes can do I/O to this device driver as they would to any other disk device driver on the system. AVD is the primary I/O interface for ACFS to perform I/O and build a file system leveraging ASM as a volume manager. DVM is loaded upon ASM start up. The device driver is cluster aware and communicates with ASM for extent map information, extent rebalancing and I/O failures.
An OS device file is created automatically when a dynamic volume is created in an ASM disk group.
Note: An AVD volume device may not be used as an OS boot or swap device, nor used as a root file system of the OS

11. What is ASM Cluster File System (ACFS)
General purpose file system for non-DB files
Journaling, extent based
POSIX, X/OPEN file system solution for UNIX/Linux
Windows file system solution for Windows platforms
Single node and cluster
Scalable and high performance
Supports NFS and CIFS protocols
Multi OS platform - Linux, Windows, Solaris and AIX
Integrated with Oracle system mgt tools
Oracle installation/configuration, EM and native OS tools
Supports advanced data services
Snapshot, Replication, Tagging, Security and Encryption
The ASM Cluster File System,(ACFS), extends Automatic Storage Management (ASM) by providing a robust, modern general purpose extent-based and journaling file system for files beyond the Oracle database files. ACFS provides support for files such as Oracle binaries, report files, trace files, alert logs and other application data files. With the addition of the ACFS, ASM becomes a complete storage management solution for both Oracle database and non-database file. ACFS scales from small files to very large files (exabytes) and supports large numbers of nodes in a cluster. ACFS is an extent-based file system to provide high performance and a utilizes a log based metadata transaction engine for file system integrity and fast recovery. The ACFS on-disk structure supports endian neutral metadata[u1]. ACFS file systems can be exported to remote clients through industry standard protocols such as NFS and CIFS.
ACFS eliminates the need for expensive 3rd party cluster file system solutions while streamlining, automating and simplifying all file type management in a single node as well as RAC and Grid computing environments. ACFS supports dynamic file system expansion and contraction without any downtime. ACFS is highly available leveraging the ASM mirroring and striping features in addition to leveraging hardware RAID functionality.  [u1]Need to say why and benefit
Journaling:
ACFS metadata is logged
Extent based:
File system is allocated and managed as extents

13. ACFS Tagging
ACFS Tagging allows group operations on files spread throughout your file systems
ACFS Tagging assigns a common naming attribute to a group of files
File operations can be performed based on tagging attributes
Tagging is configured and managed by ‘acfsutil tag’ command line
Specify tag names for directories and files
$ /sbin/acfsutil tag set –r resume /dev/asm/acfsvol /test/resumes
Comments/Harsha
1) Last bullet:- Security and Encryption do not really leverage ACFS Tagging

15. Key Drivers for Data Security & Encryption
Regulatory Compliance
Sarbanes-Oxley (SOX), J-SOX, HIPAA
GLBA
Payment Card Industry (PCI)
EU Privacy Directives, CA SB 1386….
Adequate IT controls, COSO, COBIT
Separation of duty, Proof of compliance, Risk Assessment and Monitoring
The need for Data Security solutions is being driven by two business challenges; regulatory compliance and insider threats.
Regulatory Compliance affects virtually every public company, especially those in highly regulated industries such as the financial sector. I'm sure everyone has heard of Sarbanes-Oxley. Others include the Payment Card Industry (PCI) and the Health Insurance Portability and Accountability Act (HIPAA). One of the really good things that has come out of the regulatory compliance push is that it has given organizations time and budget to go back and look at the internal processes.
The second factor driving is security is the desire to reduce the risk associated with insider threats. Some studies have concluded that upward of 80% of all threats originate from inside the organization. The issue takes on even greater significance when you consider the trend to outsourcing/offshore more IT functions.
Comment/Harsha – Just want to mention that we mainly address insider threats and encryption with our features…not so much the other topics mentioned in this slide…

Database Cloud
The data center has evolved. Mainstream customers have left the world of dedicated silos, with their physical, dedicated hardware, peak load sizing, and expensive management paradigms. They’ve moved to grids, virtualizing their resources to provide enhanced flexibility, better utilization and improved efficiencies. Now leading customers are taking the next step—consolidating their workloads into clouds, where they can rapidly provision elastic and scalable resources for workloads, and provide higher service levels even in the face of peaks in demand, and external failures.
We’re not going to spend a lot of time defining the database cloud, as there are many other presentations that tackle that topic, and there’s not yet a clear consensus on the exact definition of a cloud. In general, clouds are pools of resources, that is, hardware, software, and storage, into which you can deploy applications. The resources are shared across multiple applications. We’ve known this as consolidation and shared infrastructures, and in the cloud world it’s referred to as multi-tenancy. Resources in a cloud can be rapidly provisioned, often via a self-service infrastructure. This makes it simple to quickly deploy applications, test beds, and development platforms, increasing an organization’s agility. The resources themselves appear to be elastic. They can grow and shrink on demand, appearing infinitely scalable. Management costs are kept low via centralized management and features to automate meeting QoS objectives. End-users need not be concerned with managing the resources—rather they interact with managed services that allow them to focus on their core business. A final characteristic of the database cloud is pay-for-use-pricing. This lowers the entry cost for users, enabling new use cases that previously may have been economically unfeasible. One last point—a database cloud need not be deployed in a server virtualization environment. We will see there are multiple deployment models for the database cloud, which allow for deployment in both physical and virtual environments
