12c Multi-Tenancy and Exadata IORM: An Ideal Cloud Based Resource Management



Cloud database enables administrators to scale up and down the resource usage according to the business requirements. Oracle 12c renders multi-tenancy to manage multiple pluggable databases within a multi-tenant container database. In an Exadata, at the compute nodes, the resource manager controls the resources among pluggable databases, and all this resource management is trickled down to the storage servers, where IORM controls the resources. This presentation lucidly explains as how a business can leverage the benefits of 12C multi-tenancy, DBRM, and IORM in an Exadata realm to have an ideal cloud based resource management.

From the database notes, the I/O requests are sent to the cell nodes. These requests go through the intelligent iDB protocol containing information pieces like database name, category name, consumer group etc. These I/O requests are placed in the CELLsrv I/O queues in the order they are received. Then these I/O requests are passed to the IORM, which prioritize these requests on the basis of IORM plan and then places them accordingly into the Cell disk queues.

When I have to travel by air to somewhere, I go to a specific website to search and book my flight. Every time I visit that website, I encounter the same experience. I have to go through the same steps according to my same preferences, every time I need to book the flight.

Here is what I always do to book my flight at that website on each visit:

1. Sign in with my userid
2. Type in my origin and destination (90% of time same)
3. Type in dates
4. Sort the results by lowest price
5. Search for flights with lowest price and least hops (Direct are ideal)
6. I prefer red eye flights, so I also look for them.
7. After searching for long time, I come close to what I want and then book it.

Despite of my log-in, despite of my usual pattern of purchase, website doesn't know what I am looking for. After my log-in, all they present to me is my personal details, limited travel history, reward points, and offers based on those reward points.

In other words, they present me with Small Data.

How nice would it be, if after sign-up they ask me in simple words:

Hey Fahd, are you still your old miser-self and want to get the cheapest direct flight(s) from Darwin to Sydney at that godforsaken time at night?

I would then just laugh, click yes, give me travel dates, and they would present me with options tailored to me habits. I know they would have to go through lots of data, anlayze it, slice it, dice it, and then come up with that above statement. I know I am not their only customer, and so they have to do the same for hundreds of thousands of their customers with more complex patterns, along with sifting through data of their partner airlines, may be hotels, car rentals, etc.

In other words, they have to go through Big Data.

The massive explosion in data, combined with an ever-increasing hunger to boost processing speeds while keeping costs low, has led to engineered systems in data centers.

In cold, yet dry Manchester’s winter, it was quite thermal to simultaneously relish the meritorious UKOUG Tech13 and elite Oaktable World UK 2013 conferences. Pythian’s presence was overwhelming at both congresses. Paul Vallee, Alex Gorbachev, Elliot Zissman, Luke Davies, Paul Logan, Maris Elsins, Marc Fielding, Christo Kutrovsky and Michael McKee rocked the events.


Everyone was spoiled for the choice of the sessions. I remained focused on the engineered systems and performance tuning. Both conferences soaked me up in plenty of sessions from these tracks and much more. Jonathan Lewis talked about compression, and CBO. Tom Kyte also bestowed with his keen outlook on the various features. Pythian’s folks Luke Davies, Maris, Alex Gorbachev, and Michael Mckee shared their great insight too.




Oracle also hosted ACE dinner one evening, and it was awesome to meet yet again with numerous ACE fellows. Not only was the seven course Chinese dinner was sumptuous, the networking was delicious too. I was also honored to attend the Oaktable network fellows informal dinner at one of the Indian restaurant, and it was awesome too. Pythian and Rittman Mead also hosted drinks and dinner at a Pakistani restaurant and its really something to write home about.

While battling the jet lag the whole week long I was in UK, the proceedings of the week were very engaging and there was so much to learn and share and network. It was refreshingly great to meet yet again with the Christian Antognini, Jonathan Lewis, Heli Helskyaho, Frits Hoogland, Mark Rittman, Gunnar Bjarnason, Kyle Hailey and host of others.

Once it was over, I traveled back from one cold end of the Southern Hemisphere  to the other warm end of Northern Hemisphere.

I am reserved speaker at the UKOUG this year in Manchester and will be traveling almost full length of globe to reach Manchester next week from Australia. Looking forward for technology-packed, fun-infested event. Pythian will be there again in full force too.

Will keep you posted from there :)
