ODICS is here!!!

Posted in New Features, ODI, ODI Architecture, ODICS with tags , , on February 13, 2017 by radk00

Hi all, quick but interesting post today! Oracle has just announced its Oracle Data Integrator Cloud Service (ODICS)! You may read about it here and here. We do not have much information about it yet (if it is a complete ODI solution, how it works, if it is similar to what we did in our ODI Cloud article), but we are hoping to get those answers in “Oracle Data Integration PM Webcast – Introducing Oracle Data Integrator Cloud Service (ODICS)” that will happen on Thursday, February 16, 2017 | 11:00 am Eastern Standard Time (GMT-05:00). We encourage all of you to join the webcast and have a first look on what ODICS looks like.

——- EDIT on Feb 23 ——-

Hi all, we’ve watched the ODICS webinar and in the end we were right: ODICS is very similar to what we did on our ODI Cloud article. The only difference is that ODICS is installed directly in JCS instead of a DBCS machine as we did in the article.

In resume, ODICS is nothing more, nothing less than the current ODI 12c installed in a JCS machine that is maintained by Oracle. There is only one restriction (that may not be a big issue for some projects), that the ODI agent needs to be running in the cloud, so you may not deploy it on premise. You may watch Oracle’s ODICS webinar here. You may also know more about ODICS at Christophe blog post.

That’s it folks, exciting times are ahead of us!

Hi guys how are you? Today I want to share our new OTN article Building a 100% Cloud Solution with Oracle Data Integrator.
The article will cover how to integrate BICS, PBCS, DBCS and ODI and will explain step by step how to create a 100% cloud solution using ODI (everything on the cloud including ODI :)).

This is a perfect article for companies that are thinking to go cloud and have some doubts or even are thinking how you can integrate/use your actual infrastructure with the cloud services.

I hope you guys enjoy and see you soon.

DEVEPM will be at KScope 17!!!

Posted in ACE, EPM, Kscope 17, ODI, ODTUG on January 9, 2017 by radk00

Hi all, how are you doing? With a little delay (sorry, I was on vacation 🙂 ) we are very happy to announce that DEVEPM will be once again at KScope! We are very honored to be selected to present on the best EPM conference in the word! Here is what we are going present at Kscope 17:

Data Warehouse 2.0: Master techniques for EPM guys (powered by ODI)

“EPM environments are generally supported by a Data Warehouse, however, we often see that those DWs are not optimized for the EPM tools. During the years, we have witnessed that modeling a DW thinking about the EPM tools may greatly increase the overall architecture performance.

The most common situation found in several projects is that the people that develops the data warehouse does not have a great knowledge about EPM tools and vice-versa. This may create a big gap between those two concepts which may severally impact performance.

This session will show a lot of techniques to model the right Data Warehouse for EPM tools. We will discuss how to improve performance using partitioned tables, create hierarchical queries with “Connect by Prior”, the correct way to use Multi-Period tables for block data load using Pivot/Unpivot and more. And if you want to go ever further, we will show you how to leverage all those techniques using ODI, which will create the perfect mix to perform any process between your DW and EPM environments.”

Kscope is the largest EPM conference in the world and it will be held on San Antonio, Texas on June 2017. It will feature more than 300 technical sessions, five symposiums, deep dive sessions, and hands on labs over the course of five days.

Got interested? If you register by March 25th you’ll take advantage of the Kscope early bird rates, then don’t waste more time and let’s be part of the greatest EPM event in the world. If you are still unsure about it, read our post about how Kscope/ODTUG changed our lives! Kscope is indeed a life changer event!

ODI 12c new features: Dimension and Cubes! Part 2 (Loading using Natural Keys)

Posted in Cubes, Dimensions, ETL, New Features, ODI 12c, ODI Architecture with tags , , , , , on September 14, 2016 by radk00

Hi all, let’s continue with our posts regarding “ODI 12c new features: Dimension and Cubes”. As stated in the previous post, we can have two ways to build our new objects: with natural keys or with surrogate keys. Today’s post will focus on loading the dimensions and fact tables that where created using natural keys (please see our previous post for all the settings required for those objects).

Let’s begin loading our TIME dimension (which was mapped to our TIME Oracle table). This dimension will have information from three different source tables: SRC_YEAR, SRC_QUARTER and SRC_MONTH. Each of them has information regarding each TIME hierarchy level, so all of them needs to be loaded in order to have a complete hierarchy in our final table.

The load process is very easy and intuitive: first create a new mapping and drag and drop the TIME dimension to it. Then, just add the three source tables, map to its correspondent level in the TIME dimension and that’s it. A very cool thing here is that ODI understands each level as a “separate” table/process, so you don’t need to join your source tables before actually loading it to the target dimension. In other words, ODI allows you to have any kind of complex ETL to each dimension level and each level will be treated as “separate” data loads that will be glued together by the hierarchy setting that you mapped in the TIME dimension object. Here is what it looks like:

blog1

blog2

blog3

blog4

When you execute the mapping we are going to see that the first “MAP_BEGIN” section will try to create and truncate our stage tables that were set in our dimension object. Here is an odd thing (as we also mentioned in the last post): We could not understand yet why ODI “forces” you to have the stage tables created prior to execution (so you can select them in the Dimension object), as it could very well create them for you (like it does for C$ and I$ tables). I know that Oracle may had a reason behind it, but as for now, the entire “stage tables” thing seems an unnecessary setup. Anyway, the important thing here is that ODI will truncate the stage tables before any new execution.

blog5

In the “MAP_MAIN” section is where it gets interesting. We can see here how ODI threats this new dimension object: each level has its own ETL, as we can see that it is loading YEAR, QUARTER and MONTH separately. First YEAR step will load its source to its stage table STG_YEAR, then QUARTER step will join the information from its source table plus STG_YEAR to its STG_QUARTER table. Finally, MONTH step, that is our leaf/grain level, will join its source table plus STG_QUARTER table (which is already joined with YEAR source) and merge it all together in our final table TIME. The result will look like below:

blog6

Since we are not using Surrogate keys here, our Dimension table will contain only the grain/leaf members with all Natural Keys and its attributes for all levels that exists in the dimension. So one row will contain all information regarding all levels that it belongs to. When we create the mappings for the other two dimensions (they’re very similar, so I’m not adding them here) and execute them, we will get the following results:

blog7

blog8

Let’s to go our Fact table load. This one is way too simple, since our source table already contains all the Natural Keys that will be the ones that will also exist in our FACT table (remember, we are not dealing with Surrogate Keys in this example). Here we just need to map each NK to its respective dimension column and also our Measure data and execute the mapping.

blog9

blog10

When we take a look in Operator, we are going to see a single merge command in our Fact table, where ODI will use all dimensions to search if that row already exists in our FACT table. If it exists, the measure column is update, otherwise it is inserted.

blog11

The final result is below: as expected, all Natural Keys from our dimensions were inserted in the Fact table, together with our measure.

blog12

Now you may be wondering, why should I use these new features if it seems a lot of work (settings) for a little gain? Well, using ODI for Natural Key’s only is really not worth it, since the only benefit here seems to be ODI loading the dimensions levels all at once, with different sources/ETL, in a single mapping object, which is a very cool feature, since it enables us to better organize our DW objects and have a clear view on our ETL logic. But again, this is too little for the amount of work that we need to do to get there. But don’t worry, it will get way better when we start to work with Surrogate Keys, since ODI will be able to abstract all the Surrogate Key management and you will start to feel that all the necessary settings will finally be worth the work.

That’s it for today folks! We will be releasing the Surrogate Key settings and load posts very soon, so stay tuned in our blog! See ya!

PBCS, BICS, DBCS and ODI!!! Is that possible???

Posted in 11.1.1.9.0, 11.1.2.4, ACE, BICS, DBCS, EPM, EPM Automate, ODI, ODI 10g, ODI 11g, ODI 12c, ODI Architecture, ODI Architecture, Oracle, OS Command, PBCS, Performance, Uncategorized with tags , , , , , , , on August 15, 2016 by RZGiampaoli

Hey guys, today I’ll talk a little bit about architecture, cloud architecture.

I just finished a very exciting project in Brazil and I would like to share how we put everything together for a 100% cloud solution that includes PBCS, BICS, DBCS and ODI. Yes ODI and still 100% cloud.

Now you would be thinking, how could be 100% cloud if ODI isn’t cloud yet? Well, it can be!

This client doesn’t have a big IT infrastructure, in fact, almost all client’ databases are supported and hosted by providers, but still, the client has the rights to have a good forecast and BI tool with a strong ETL process behind it right?

Thanks to the cloud solutions, we don’t need to worry about infrastructure anymore (or almost), the only problem is… ODI.

We still don’t have a KM for cloud services, or a cloud version of ODI, them basically we can’t use ODI to integrate could tools….

Or can we? Yes we can 🙂

The design is simple:

  1. PBCS: Basically we’ll work in the same way we would if it was just it.
  2. BICS: Same thing here, but instead of use the database that comes with BICS, we need to contract a DBCS as well and point the DW schema to it.
  3. DBCS: here’s the trick. Oracle’s DBCS is not else then a Linux machine hosted in a server. That means, we can install other things in the server, other things like ODI and VPN’s.
  4. ODI: we just need to install it in the same way we would do in an on premise environment, including the agent.
  5. VPN’s: the final touch, we just need to create VPN’s between the DBCS and the client DB’s, this way ODI will have access to everything it needs.

Yes you read it right, we can install ODI in the DBCS, and that makes ODI a “cloud” solution.

cloud solution

The solution looks like this:

BICS: It’ll read directly from his DW schema in the DBCS.

PBCS: There’re no direct integration between the PBCS and DBCS (where the ODI Agent is installed), but I found it a lot better and easy to integrate them using EPM Automate.

EPM Automate: With EPM Automate we can do anything we want, extract data and metadata, load data and metadata, execute BR and more. For now the easiest way to go is create a script and call it from ODI, passing anything you need to it.

VPN’s: For each server we need to integrate we’ll need one VPN created. With the VPN between the DBCS and the hosts working, use ODI is extremely strait forward, we just need to create the topology as always, revert anything we need and work in the interfaces.

And that’s it. With this design you can have everything in the cloud and still have your ODI behind scenes! By the way, you can exactly the same thing with ODI on premise and as a bonus you can get rid of all VPN’s.

In another post I’ll give more detail about the integration between ODI and PBCS using EPM Automate, but I can say, it works extremely well and as far I know is a lot easier than FDMEE (at least for me).

Thanks guys and see you soon.
