Transitioning to the cloud may moreover live a daunting thought. Logging into a cloud portal for the first time and never realizing where the comfort is or the pass to execute probably the most basic projects can elicit self-doubt in even probably the most experienced technologist. For some, it could consider similar to starting over. this article goals to squelch that self-doubt for those getting into the Oracle Cloud by pass of presenting enough competencies to collect begun with Oracle Cloud Infrastructure Database functions—without retard and with self assurance.classic Versus OCI
There are two models of Oracle Cloud. The existing “2d generation” platform is known as Oracle Cloud Infrastructure (OCI). When Oracle first entered the public cloud market, the product was referred to as Oracle Public Cloud (OPC). most of the OPC functions are noiseless vigorous and elope separately from OCI. In most instances, the pass to differentiate between them is to hunt the term “classic.” This suggests that the provider is a fraction of the daily OPC infrastructure. OPC changed into later renamed OCI-classic. anything now not called basic is a component of OCI.Portals
for those who first badge into your Oracle Cloud account, you're going to doubtless live on the “Dashboard” or “My functions” page. here is the precise-degree portal which has access to each OCI and OCI-classic capabilities. The slide-out pane on the left of the dashboard has a list of the entire capabilities purchasable to your account. opting for a basic service similar to “Compute classic” will bring you to a divorce portal for the Compute traditional service. selecting any carrier that isn't a classic carrier similar to “Compute” will convey you to the Compute OCI service web page in the OCI portal. The incompatibility is exquisite but crucial. The classic functions believe their own isolated portals. The OCI features are each and every a fraction of the equal OCI portal.
The slide-out pane on the left changes, counting on the character of portal you are in. The Dashboard portal will array the OCI-classic and OCI functions. when you are in any of the OCI functions, the pane will now not exhibit any OCI-classic capabilities however will encompass the paths to each and every different OCI services.Tenancy
The long-established Oracle Cloud, now called OCI-classic, spoke of debts as “identification domains.” but that term hasn’t truly carried over to OCI. as an alternative, everything is in accordance with the theory of a “tenancy” within OCI. For each and every intents and functions, the tenancy can live considered the “account.”cubicles
Multitenancy in OCI extends a ways past the database. There are myriad ways of setting apart OCI accessories and one of the crucial maximum tiers is “compartments.” booths are a rational grouping of cloud resources. Privileges (formally called IAM policies) can moreover live applied at the compartment stage, signification that there are moreover purposeful merits of booths beyond rational separation and company. cubicles are a fraction of OCI handiest. not one of the traditional features will invent the most of or live limited through compartments or another OCI governance components.
All OCI provider accessories are remoted by Compartment. that you may descry the Compartment wherein you presently live in any provider by pass of searching under the “record Scope” header on the left aspect of the reveal. If at any time you don’t descry the carrier add-ons you are searching for, invent certain the material Compartment is chosen.
The route to booths administration will moreover live present in the left slide-out pane below the “id” menu. A “root” Compartment is created when your account is first provisioned. before you delivery provisioning features, you're going to must create at the least one extra Compartment.digital Cloud Networks
A digital Cloud community (VCN) is a bunch of networking add-ons used by most OCI capabilities. A VCN intently resembles a daily network, with firewall rules and quite a lot of styles of gateways to talk across internal networks and over the internet.
Most capabilities require a VCN to exist before they can moreover live provisioned. Some services, such as the Compute service, will supply the alternative of growing the VCN as fraction of the provisioning system.
The minimal advent of a VCN will handiest provision one of the vital accessories required. The easiest pass of constructing bound the VCN has every tiny thing vital for a useful and accessible instance is to opt for “Create digital Cloud network Plus linked resources” when creating the VCN. this could add a web Gateway to allow entry to your capabilities over the information superhighway, a subnet for every of the supply Domains within the area, DNS resolution, and dynamic IP addresses.
here's where OCI differs from probably the most different fundamental cloud providers. With OCI, you ought to installation at the least one VCN and the linked substances earlier than that you could birth provisioning and the usage of other infrastructure and substances. This contrasts with some other major cloud providers where the community fundamentals are finished instantly or with the aid of default.SSH Keys
it's required that you create a shared SSH (relaxed Shell) key pair before provisioning an illustration. a typical strategy to try this is to invent employ of the PuTTY suite of SSH equipment, chiefly the PuTTY Key Generator. lots of the SSH key generator tools finish not store the generic public key in the structure that OCI functions expect. To create the generic public key file, readily copy the textual content from the key generator below the heading, “Public key for pasting into OpenSSH authorized_keys file,” and redeem it to a file. Don’t overlook to store the inner most key as well.Compute
With a VCN in region and an SSH key pair created, a Compute case will moreover live provisioned. OCI goes beyond OCI-basic with the aid of adding the capability to provision naked metal Machines, which gives you a dedicated physical server.
as an example, to create a fundamental Linux virtual computer (VM), elect “cases” below the Compute menu from the slide-out pane on the left. When deciding on the SSH key file, elect the file onto which you copied the OpenSSH formatted public key. the entire networking components should default to the VCN add-ons you created.
It won’t pick long for the VM to live in a working state, at which factor that you can log into it with SSH. When developing your SSH connection, live certain to invent employ of shared key authentication and elect the SSH deepest key file. The username for Oracle Linux compute instances is “opc,” which is likely one of the many remnants left over from the long-established Oracle Public Cloud. The opc consumer has permission to carried out privileged operations the usage of sudo.Database
The OCI Database provider has must haves similar to the Compute service. here's often as a result of the incontrovertible fact that compute situations are created to assist the database.
select “bare metallic, VM, and Exadata” under the “Database” heading from the slide-out pane on the left. invent positive the suitable Compartment is chosen and elect “Launch DB device.”
“shape” shows the dimension of the compute instance(s) a helpful pass to advocate the database. The shape quantity suggests the compute potential of the illustration. the primary number shows the hardware platform on which the illustration will run: 1 shows that the case will elope on an Oracle X5 server, whereas 2 indicates the instance will elope on an Oracle X7 server. The 2d number suggests the variety of CPU cores that could live allotted. making a option on a shape with a pair of CPU will can aid you select up to 2 nodes for an non-compulsory RAC (true software Clusters) database configuration.
“utility editions” shows that certain database points are enabled. here listing indicates which edition and lines are enabled for each and every choice. each and every commercial enterprise edition includes the aspects of the reduce enterprise editions.
special consideration should noiseless live taken when choosing “License type” since the rate change is gigantic. as an example, the usage of “Pay as You Go” pricing for a solitary vehement performance VM, the bring Your own License (BYOL) cost is approximately $0.29 per CPU per hour versus the included license saturate of $2.52 per CPU per hour. including the license makes the illustration nearly nine times extra costly.
The “available Storage dimension” option is a tiny delusive because it most effectual money owed for a factor of what Oracle will really cost for storage for this VM. The “complete Storage size” reflects the whole storage consumed by means of the VM. The purchasable storage dimension is the measurement of the +records ASM disk neighborhood. The +RECO disk community will even live created with 256GB of area. The storage allotted to the OS makes up the leisure. picking 256GB will influence in a total storage allocation of 712GB. choosing a bigger storage size only impacts the measurement of the +records disk neighborhood.
The obtainable database versions as of February 2019 are 18.0, 22.214.171.124, 126.96.36.199, and 11.2.0.four. except for edition eleven.2, the created database can live a multitenant database, even with no matter if you elect to create a pluggable database (PDB) each and every through the provisioning manner.The direction ahead
Navigating Oracle Cloud Infrastructure Database functions can live a bit overwhelming in the beginning. besides the fact that children, creating Compute and Database instances in OCI is relatively effortless as Oracle has constrained most of the alternate options purchasable when configuring an Oracle Database gadget. one of the vital terminology may well live unfamiliar however it should now not live difficult to master for a pro Oracle DBA transitioning to a cloud database architect.
Managing OCI Database situations once they're created poses extra challenges. The next article in this collection will verify database administration and administration projects such as backups, pluggable databases, records defend, and client networking.

Transitioning to the cloud can live a daunting thought. Logging into a cloud portal for the first time and not knowing where anything is or how to execute the most basic tasks can elicit self-doubt in even the most experienced technologist. For some, it may feel similar to starting over. This article aims to squelch that self-doubt for those pitiful into the Oracle Cloud by providing enough information to collect started with Oracle Cloud Infrastructure Database Services—quickly and with confidence.Classic Versus OCI
There are two versions of Oracle Cloud. The current “second generation” platform is called Oracle Cloud Infrastructure (OCI). When Oracle first entered the public cloud market, the product was called Oracle Public Cloud (OPC). Many of the OPC services are noiseless vigorous and elope separately from OCI. In most cases, the pass to differentiate between them is to study for the term “Classic.” This indicates that the service is fraction of the original OPC infrastructure. OPC was later renamed OCI-Classic. Anything not referred to as Classic is fraction of OCI.Portals
When you first badge into your Oracle Cloud account, you will probably live on the “Dashboard” or “My Services” page. This is the top-level portal which has access to both OCI and OCI-Classic services. The slide-out pane on the left of the dashboard has a list of each and every of the services available to your account. Selecting a Classic service such as “Compute Classic” will bring you to a divorce portal for the Compute Classic service. Selecting any service that is not a Classic service such as “Compute” will bring you to the Compute OCI service page in the OCI portal. The incompatibility is subtle but important.

Multitenancy in OCI extends far beyond the database. There are myriad ways of isolating OCI components and one of the highest levels is “Compartments.” Compartments are a rational grouping of cloud resources. Privileges (officially called IAM Policies) can moreover live applied at the compartment level, signification that there are moreover practical benefits of compartments beyond rational separation and organization. Compartments are fraction of OCI only. no one of the Classic services will utilize or live constrained by compartments or any other OCI governance components.
All OCI service components are isolated by Compartment. You can descry the Compartment in which you currently reside in any service by looking under the “List Scope” header on the left side of the screen.

The path to Compartments administration can live organize in the left slide-out pane under the “Identity” menu. A “root” Compartment is created when your account is first provisioned. Before you start provisioning services, you will believe to create at least one additional Compartment.Virtual Cloud Networks
A Virtual Cloud Network (VCN) is a group of networking components used by most OCI services. A VCN closely resembles a traditional network, with firewall rules and various types of gateways to communicate across internal networks and over the internet.
Most services require a VCN to exist before they can live provisioned. Some services, such as the Compute service, will give the option of creating the VCN as fraction of the provisioning process.
The minimal creation of a VCN will only provision some of the components required. The easiest pass of making positive the VCN has everything needed for a functional and accessible instance is to select “Create Virtual Cloud Network Plus Related Resources” when creating the VCN. This will add an Internet Gateway to allow access to your services over the internet, a subnet for each of the Availability Domains in the region, DNS resolution, and dynamic IP addresses.
This is where OCI differs from some of the other major cloud providers. With OCI, you must set up at least one VCN and the associated resources before you can start provisioning and using other infrastructure and resources. This contrasts with some other major cloud providers where the network basics are done automatically or by default.SSH Keys
It is required that you create a shared SSH (Secure Shell) key pair before provisioning an instance. A common pass to finish this is to employ the PuTTY suite of SSH tools, specifically the PuTTY Key Generator. Many of the SSH key generator tools finish not redeem the public key in the format that OCI services expect. To create the public key file, simply copy the text from the key generator under the heading, “Public key for pasting into OpenSSH authorized_keys file,” and redeem it to a file. Don’t forget to redeem the private key as well.Compute
With a VCN in situation and an SSH key pair created, a Compute Instance can live provisioned. OCI goes beyond OCI-Classic by adding the aptitude to provision Bare Metal Machines, which gives you a dedicated physical server.
For example, to create a basic Linux Virtual Machine (VM), select “Instances” under the Compute menu from the slide-out pane on the left. When choosing the SSH key file, select the file onto which you copied the OpenSSH formatted public key. each and every of the networking components should default to the VCN components you created.
It won’t pick long for the VM to live in a running state, at which point you can log into it with SSH. When setting up your SSH connection, invent positive to employ shared key authentication and elect the SSH private key file. The username for Oracle Linux compute instances is “opc,” which is one of the many remnants left over from the original Oracle Public Cloud. The opc user has permission to performed privileged operations using sudo.Database
The OCI Database service has prerequisites similar to the Compute service. This is mostly due to the fact that compute instances are created to advocate the database.
Select “Bare Metal, VM, and Exadata” under the “Database” heading from the slide-out pane on the left. invent positive the remedy Compartment is selected and select “Launch DB System.”
“Shape” indicates the size of the compute instance(s) that will advocate the database. The shape number indicates the compute capability of the instance. The first number indicates the hardware platform on which the instance will run: 1 indicates that the instance will elope on an Oracle X5 server, while 2 indicates the instance will elope on an Oracle X7 server. The second number indicates the number of CPU cores that will live allocated. Choosing a shape with more than one CPU will allow you to select up to two nodes for an optional RAC (Real Application Clusters) database configuration.
“Software Editions” indicates that certain database features are enabled. The following list indicates which version and features are enabled for each option. Each Enterprise edition includes the features of the lower Enterprise editions.
Special consideration should live taken when selecting “License Type” because the price incompatibility is significant. For example, using “Pay as You Go” pricing for a solitary Extreme Performance VM, the Bring Your Own License (BYOL) cost is approximately $0.29 per CPU per hour versus the included license cost of $2.52 per CPU per hour. Including the license makes the instance almost nine times more expensive.
The “Available Storage Size” option is a tiny delusive because it only accounts for a portion of what Oracle will actually saturate for storage for this VM. The “Total Storage Size” reflects the total storage consumed by the VM. The available storage size is the size of the +DATA ASM disk group. The +RECO disk group will moreover live created with 256GB of space. The storage allocated to the OS makes up the rest. Selecting 256GB will result in a total storage allocation of 712GB. Selecting a larger storage size only affects the size of the +DATA disk group.
The available database versions as of February 2019 are 18.0, 184.108.40.206, 220.127.116.11, and 18.104.22.168. With the exception of version 11.2, the created database will live a multitenant database, regardless of whether you elect to create a pluggable database (PDB) during the provisioning process.The Path Forward
Navigating Oracle Cloud Infrastructure Database Services can live a tiny overwhelming at first. However, creating Compute and Database Instances in OCI is relatively smooth as Oracle has limited many of the options available when configuring an Oracle Database system. Some of the terminology may live unfamiliar but it should not live difficult to master for a seasoned Oracle DBA transitioning to a cloud database architect.
Managing OCI Database Instances once they are created poses additional challenges. The next article in this progression will examine database management and administration tasks such as backups, pluggable databases, Data Guard, and client networking.

The sheer breadth and depth of Oracle's certification program is rife with occasion for professionals who want to travail with Oracle technologies, or who already finish and want their skills to live recognized and validated. Although there are many specific Oracle products to specialize on in varying capacities, the main job roles are administrators, architects, programmers/developers and implementation specialists.
Every company that runs Oracle Database, Oracle Cloud, Oracle Linux or Solaris, Oracle operating systems and so on needs qualified administrators to deploy, maintain, monitor and troubleshoot these solutions. They moreover exigency architects to pass and design solutions that meet commerce needs and are preempt to the specific environments in which they’re deployed.
On the evolution front, ComputerWorld indicates that programmers and developers continue to live "leading players in the IT world." That magazine ranks associated skills as the most sought-after by hiring managers in 2017, tied with aid desk support. (Database administration isn't far behind.) A quick search on Indeed.com results in over 12,000 hits for "Oracle developer," which is a noteworthy indication of both exigency and desire. Not only finish developers create and modify Oracle software, they often must know how to design software from the bottom up, package products, import data, write scripts and develop reports.
And of course, Oracle and its partners will always exigency implementation specialists to sell and deploy the company's solutions. This role is typically accountable for tasks that must live accomplished to collect a solution up and running in a client's environment, from creating a project pass and schedule, to configuring and customizing a system to match client specifications.Oracle Training and Resources
It's not surprising that Oracle has an extensive library of exam preparation materials. Check the Oracle University website (education.oracle.com) for hands-on instructor-led training, virtual courses, training on demand, exam preparation seminars, practice exams and other training resources.
A candidate's best bet, however, is to first elect a certification path and then supervene the links on the Oracle website to the required exam(s). If training is recommended or additional resources are available for a particular exam, Oracle lists them on the exam page.
Another noteworthy resource is the Oracle Learning Paths web page, which provides a lengthy list of Oracle product-related job roles and their recommended courses.
Iron Man uses Exadata (Image Source — https://goo.gl/Mwt8mA)Whenever I used to hear this term called as “Exadata” — I’d contemplate to myself — What is Exadata anyway? Is it some kind of a database? A storage appliance? An extremely fast server?
I was under the imprint that there’s something very complicated and a very technically challenging architecture behind it which probably would live pass too difficult to understand.
Apparently, I was right! ;)
When I started working first with Exadata, in my first consulting experience, my learning curve was fairly abrupt and I had to grasp complexities of the project quickly, understand and implement Exadata with a team of DBAs deployed at an aviation client’s environment.
It could live with your case that you’re currently a DBA and your client may or may not believe an Exadata environment. They as DBAs always believe an itch to learn and try something new every time there’s a new feature, version or even a product is announced. Thankfully, I had the occasion to play with Exadata thus I decided to collect my hands dirty.
Disclaimer — Please collect used to the following terms when you’re learning Exadata for the first time — they can live used interchangeably to represent the Exadata components (wink wink) — “extreme”,”smart”,”intelligent”,”flash”
Before I abysmal dive into architectural components and how and why things believe been setup the pass they are in Exadata, I’d fancy to confess that I’m noiseless learning my around with this mammoth of a machine. It’s fairly curious to descry the evolution of Exadata with time.
<history>- Exadata is an offshoot of Storage Appliance for Grid Environments(SAGE) project, the working cognomen for Oracle Exadata Database Machine, began about three years before the product’s final release in 2008. It’s a database machine designed by Oracle to elope Oracle database software and is a combination of compute (database) and storage systems. Starting with version X1, Exadata has arrive a long way! </history>
In any typical bare-metal server, the ROI on investments basically depends on how swiftly can you serve your clients through your applications. For this you definitely exigency a robust IT infrastructure, most of the servers which are there as of now supervene the scale-up architecture, but Exadata follows scale-out architecture. Since everything boils down to one word “performance”.
I am skipping the hardware configuration fraction of Exadata, since Oracle itself has shared a lot of information on the current hardware configuration here for Exadata X-6 — http://www.oracle.com/technetwork/database/exadata/exadata-x6-2-ds-2968790.pdf.
The latest version of Exadata that has been released is X-6. X-6 offers umpteen benefits compared to it’s predecessors, just advocate in repartee that it’s moreover an expensive investment. https://cloud.oracle.com/database/exadata/pricing. Just cautionary price sharing. :)
Exadata is made up following components –
1) Database Servers aka Compute Nodes — where Oracle database resides.
2) Exadata Storage Cells aka Storage Nodes — uses a command line utility called as CellCLI to manage storage.
3) InfiniBand switches — for lofty speed (read extreme) connectivity between storage and database servers.
4) PDU and Ethernet Switches — Extra PDUs (Power Distribution Units) in case of any failure for the sake of redundancy.
(Image Source — https://goo.gl/QSlULs)
Initially, Exadata offered two flavours of Exadata Storage servers — High Performance and lofty Capacity but after X5, they changed to lofty Performance and Extreme glance storage.
The odds of Exadata Storage server Extreme glance is that it’s performance is orders of magnitude faster than traditional storage array architectures, and is moreover much faster than current all-flash storage arrays. Oracle moreover guarantees that the performance of extreme glance won’t wean off with time.
Now, let’s understand what kind of things to expect when you start working on Oracle Exadata database machine for the first time. In the Database Servers aka Compute Nodes believe following software components pre-configured when you collect the brand new rack installed on your premises -
1) OS (Oracle Enterprise Linux Flavour)
2) Oracle Home (has 2 primary homes — one for the database and another for the grid infrastructure)
3) RAC and ASM pre-configured
4) DBFS for sharing the file system for Oracle internal files
In the Exadata Storage Cells or Servers believe following software components pre-configured -
1) OS (Oracle Enterprise Linux Flavour)
2) CELLSRV (Cell Server)
3) Management Server (MS)
4) Restart Server (RS)
Following X-5, Oracle introduced Exadata with Extreme Smart glance Cache. With the X5s, you exigency to elect between the lofty Capacity and lofty Performance cells with regards to the number of glance cards which arrive with the configuration. Since the X5s lofty Performance Storage Servers finish not believe any arduous disks for database storage, the glance devices will live used to store database files persistently in addition to acting as a storage layer cache for the RDBMS layer I/O requests.
<MagicSauce> iDB protocol — Oracle developed the iDB protocol to elope across the InfiniBand network. The iDB protocol is not available to databases running on non-Exadata hardware. iDB is mainly used for predicate filtering which is the cherry on top offering for query offloading . The iDB protocol used to interact with the Exadata storage cells includes the predicate information in its requests, predicate filtering is accomplished by performing the standard filtering operations at the storage flush before returning the data. each and every ASM disks on Exadata are accessed via the iDB protocol. </MagicSauce>
I’d debate the advantages of Oracle Exadata where it scores the most and why you or your client can fade ahead with Exadata as an investment for your business.
1) Time to Market — This is something that every IT organization deals with, from the project kick-off till it’s implementation and production takes a long time. Exadata as being an engineered system which is pre-configured before it’s delivered to you. It does quit up saving many man hours on setting up the infrastructure. Also, Exadata can house each and every your PROD/DEV/TEST environments into one.
2) RAC Ready — Exadata comes pre-configured with ASM and RAC, which saves your DBA’s time to configure everything from scratch.
3) solitary Vendor — “The buck stops here.” Oracle owns the whole stack so there cannot live and will not live any guilt game when there’s any issue. So whether it’s database, hardware or any network issue, Oracle is amenable for 100% of it.
Lastly, as I am myself preparing for Exadata Certification, I’d fancy to partake that thankfully, Exadata certification track does not yet require one to believe a prior OCA/OCP certification. Currently, Oracle University provides training on X-6 machine, but the Exadata exam as of now can live taken on X-3, X-4 and X-5 administration. More information available here -http://education.oracle.com/pls/web_prod-plq-dad/ou_product_category.getPageCert?p_cat_id=212
Hope this information helped you collect off the ground regarding what and why of Oracle Exadata.
Please finish partake your feedback or just partake your undergo with this mammoth of a machine, would saturate for to hear from you. Thank you for reading thus far. tickle pat yourself on the back! :)
