  • Oracle SOA Suite, the Most Capable Tool for Every Possible Integration Challenge

    - by Demed L'Her
    session ID: CON8601 - when: Monday, Oct. 1, 10:45am-11:45am - where: Moscone South 102 "Oracle SOA Suite, the Most Capable Tool for Every Possible Integration Challenge" is the name of the session I will be delivering at Oracle OpenWorld this year. I'm usually going for more subdued titles but decided to remove the gloves this year, at the risk of sounding arrogant! While we have a number of worthy competitors in various areas of integration no one can really compete with the breadth and reliability of Oracle SOA Suite. This session is primarily intended for people who are not yet familiar with Oracle SOA Suite (i.e. if you are an existing customer your time might be better spent at some of the other sessions we have on the topic). I will provide an overview of Oracle SOA Suite, the customers using it and the types of challenges they are solving with it: from integrating Oracle Applications (E-Business Suite, Siebel, PeopleSoft, RightNow, Taleo etc.) to third-party applications (did you know that over a third of our customers actually use us to integrate SAP?), mainframes and a variety of technologies. We will talk about some emerging trends and problems that our users are solving with the product: cloud integration, B2B consolidation and mobile-enablement. I will also briefly touch upon the exciting projects we are doing with Oracle Event Processing, in the domain of "Fast Data" and "Big Data". Last but not least, I will be joined on stage by Venktesh Maudgalya, Director at Electronic Arts. Venktesh will bring his customer perspective and explain how EA leveraged Oracle SOA Suite to implement iHub, the massive integration hub that interconnects all their applications (E-BusinessSuite, Hyperion, Demantra, Peoplesoft, Salesforce.com, Kronos, Teradata, GXS etc.) and carries 3/4 of their revenue flows. I just picked up my badge and will be kicking off the festivities tomorrow talking to partners in a pre-OOW briefing at the Oracle Headquarters - see you next week! PS: if you're going to tweet about Oracle SOA Suite next week please make sure to use the #oraclesoa and #oow hashtags so that we can track and amplify your tweets!

  • Methods to Validate User Supplied Data

    - by clifgray
    I am working on a website where users record data from certain locations and they input an address to tag that location with a GPS coordinate. Pretty frequently those locations are tagged more than a mile away from the actual location and I am trying to implement a few ways to validate the data. Right now I am thinkiing of: having a tag of location pages for other users to say "incorrect location" so I can go one by one and fix it letting users with a decent amount of experience (reputation) edit the location GPS coordinates making the location be validated by a mod before it goes live and they make sure it is a good location Are these reasonable? I know the first will take a lot of my time and I would love some suggestions.

  • Use MD5 to validate the exchanged files between Oracle and Customer

    - by Jie Chen
    Oracle Supports may ask customers to upload some data files (Database Dump, Trace Log, etc) for research. We often see the scenario that the uploaded huge files are corrupted and have to ask to re-upload. Then we may waste much time during this period. To avoid this, customers can tell Support the MD5 checksum of the upload files, requesting support to validate same if they have gotten the correct file in good format. MD5 on Linux We can use "md5sum" command directly. For example we calculate the file PrintManager.class MD5 checksum value. [jijichen@jclinux temp]$ md5sum PrintManager.class e0bf8c7623240ccd15ee17c0478427a1 PrintManager.class MD5 on Windows There are many freeware to calculate MD5 on internet. For example we can use WinMD5Free tool. You can download it from here. http://www.winmd5.com https://blogs.oracle.com/jiechen/resource/2013/winmd5free.zip

  • Solving Big Problems with Oracle R Enterprise, Part I

    - by dbayard
    Abstract: This blog post will show how we used Oracle R Enterprise to tackle a customer’s big calculation problem across a big data set. Overview: Databases are great for managing large amounts of data in a central place with rigorous enterprise-level controls.  R is great for doing advanced computations.  Sometimes you need to do advanced computations on large amounts of data, subject to rigorous enterprise-level concerns.  This blog post shows how Oracle R Enterprise enables R plus the Oracle Database enabled us to do some pretty sophisticated calculations across 1 million accounts (each with many detailed records) in minutes. The problem: A financial services customer of mine has a need to calculate the historical internal rate of return (IRR) for its customers’ portfolios.  This information is needed for customer statements and the online web application.  In the past, they had solved this with a home-grown application that pulled trade and account data out of their data warehouse and ran the calculations.  But this home-grown application was not able to do this fast enough, plus it was a challenge for them to write and maintain the code that did the IRR calculation. IRR – a problem that R is good at solving: Internal Rate of Return is an interesting calculation in that in most real-world scenarios it is impractical to calculate exactly.  Rather, IRR is a calculation where approximation techniques need to be used.  In this blog post, we will discuss calculating the “money weighted rate of return” but in the actual customer proof of concept we used R to calculate both money weighted rate of returns and time weighted rate of returns.  You can learn more about the money weighted rate of returns here: http://www.wikinvest.com/wiki/Money-weighted_return First Steps- Calculating IRR in R We will start with calculating the IRR in standalone/desktop R.  In our second post, we will show how to take this desktop R function, deploy it to an Oracle Database, and make it work at real-world scale.  The first step we did was to get some sample data.  For a historical IRR calculation, you have a balances and cash flows.  In our case, the customer provided us with several accounts worth of sample data in Microsoft Excel.      The above figure shows part of the spreadsheet of sample data.  The data provides balances and cash flows for a sample account (BMV=beginning market value. FLOW=cash flow in/out of account. EMV=ending market value). Once we had the sample spreadsheet, the next step we did was to read the Excel data into R.  This is something that R does well.  R offers multiple ways to work with spreadsheet data.  For instance, one could save the spreadsheet as a .csv file.  In our case, the customer provided a spreadsheet file containing multiple sheets where each sheet provided data for a different sample account.  To handle this easily, we took advantage of the RODBC package which allowed us to read the Excel data sheet-by-sheet without having to create individual .csv files.  We wrote ourselves a little helper function called getsheet() around the RODBC package.  Then we loaded all of the sample accounts into a data.frame called SimpleMWRRData. Writing the IRR function At this point, it was time to write the money weighted rate of return (MWRR) function itself.  The definition of MWRR is easily found on the internet or if you are old school you can look in an investment performance text book.  In the customer proof, we based our calculations off the ones defined in the The Handbook of Investment Performance: A User’s Guide by David Spaulding since this is the reference book used by the customer.  (One of the nice things we found during the course of this proof-of-concept is that by using R to write our IRR functions we could easily incorporate the specific variations and business rules of the customer into the calculation.) The key thing with calculating IRR is the need to solve a complex equation with a numerical approximation technique.  For IRR, you need to find the value of the rate of return (r) that sets the Net Present Value of all the flows in and out of the account to zero.  With R, we solve this by defining our NPV function: where bmv is the beginning market value, cf is a vector of cash flows, t is a vector of time (relative to the beginning), emv is the ending market value, and tend is the ending time. Since solving for r is a one-dimensional optimization problem, we decided to take advantage of R’s optimize method (http://stat.ethz.ch/R-manual/R-patched/library/stats/html/optimize.html). The optimize method can be used to find a minimum or maximum; to find the value of r where our npv function is closest to zero, we wrapped our npv function inside the abs function and asked optimize to find the minimum.  Here is an example of using optimize: where low and high are scalars that indicate the range to search for an answer.   To test this out, we need to set values for bmv, cf, t, emv, tend, low, and high.  We will set low and high to some reasonable defaults. For example, this account had a negative 2.2% money weighted rate of return. Enhancing and Packaging the IRR function With numerical approximation methods like optimize, sometimes you will not be able to find an answer with your initial set of inputs.  To account for this, our approach was to first try to find an answer for r within a narrow range, then if we did not find an answer, try calling optimize() again with a broader range.  See the R help page on optimize()  for more details about the search range and its algorithm. At this point, we can now write a simplified version of our MWRR function.  (Our real-world version is  more sophisticated in that it calculates rate of returns for 5 different time periods [since inception, last quarter, year-to-date, last year, year before last year] in a single invocation.  In our actual customer proof, we also defined time-weighted rate of return calculations.  The beauty of R is that it was very easy to add these enhancements and additional calculations to our IRR package.)To simplify code deployment, we then created a new package of our IRR functions and sample data.  For this blog post, we only need to include our SimpleMWRR function and our SimpleMWRRData sample data.  We created the shell of the package by calling: To turn this package skeleton into something usable, at a minimum you need to edit the SimpleMWRR.Rd and SimpleMWRRData.Rd files in the \man subdirectory.  In those files, you need to at least provide a value for the “title” section. Once that is done, you can change directory to the IRR directory and type at the command-line: The myIRR package for this blog post (which has both SimpleMWRR source and SimpleMWRRData sample data) is downloadable from here: myIRR package Testing the myIRR package Here is an example of testing our IRR function once it was converted to an installable package: Calculating IRR for All the Accounts So far, we have shown how to calculate IRR for a single account.  The real-world issue is how do you calculate IRR for all of the accounts?This is the kind of situation where we can leverage the “Split-Apply-Combine” approach (see http://www.cscs.umich.edu/~crshalizi/weblog/815.html).  Given that our sample data can fit in memory, one easy approach is to use R’s “by” function.  (Other approaches to Split-Apply-Combine such as plyr can also be used.  See http://4dpiecharts.com/2011/12/16/a-quick-primer-on-split-apply-combine-problems/). Here is an example showing the use of “by” to calculate the money weighted rate of return for each account in our sample data set.  Recap and Next Steps At this point, you’ve seen the power of R being used to calculate IRR.  There were several good things: R could easily work with the spreadsheets of sample data we were given R’s optimize() function provided a nice way to solve for IRR- it was both fast and allowed us to avoid having to code our own iterative approximation algorithm R was a convenient language to express the customer-specific variations, business-rules, and exceptions that often occur in real-world calculations- these could be easily added to our IRR functions The Split-Apply-Combine technique can be used to perform calculations of IRR for multiple accounts at once. However, there are several challenges yet to be conquered at this point in our story: The actual data that needs to be used lives in a database, not in a spreadsheet The actual data is much, much bigger- too big to fit into the normal R memory space and too big to want to move across the network The overall process needs to run fast- much faster than a single processor The actual data needs to be kept secured- another reason to not want to move it from the database and across the network And the process of calculating the IRR needs to be integrated together with other database ETL activities, so that IRR’s can be calculated as part of the data warehouse refresh processes In our next blog post in this series, we will show you how Oracle R Enterprise solved these challenges.

    - by abhi
    I have installed Oracle 10g Express edition in Ubuntu 10.10 and it doesn't show or ask to give my password during installation. When I click on "start database" it gave the warning "Operation failed, abhi is not a member of 'dba' group." and when clink on "Run SQL command line" it shows /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.sh: 114: [[: not found When I click on "GOTO Database home page", it opens Mozilla's "Ubuntu Google search page". Can anyone help me get my Oracle to work or tell me how to remove that because it is also not getting removed. I tried all the commands that are given as suggestions by Ubuntu. Please help me because I don't want to format my Ubuntu.

  • 81% of European Shoppers Willing to Pay More for Better Customer Experience

    - by Richard Lefebvre
    Customer Experience provides strategic driver for business growth Research released today from Oracle has revealed that customer experience is now a key driver for revenue growth in Europe, and an effective channel for brand differentiation in a globalized economy where products and services are increasingly commoditized. The research report, “Why Customer Satisfaction is No Longer Good Enough,” reveals that 81% of consumers surveyed are willing to pay more for superior customer experience. With nearly half (44%) willing to pay a premium of more than 5%. Improvement of the overall customer experience (40%), providing quick access to information and making it easier for customers to ask questions (35%) were cited as key drivers for spending more with a brand. The pan-European research, carried out in June 2012 by independent research company Loudhouse, surveyed 1400 online shoppers (50% female, 50% male) who had made a complaint or enquiry to a customer service department in the last 12 months.

  • Materialized View vs POJO View based on Objects representing Oracle tables

    - by Zack Macomber
    I have about 12 Oracle tables that represent data that's being integrated from an external system into my web application. This data is going to be used in an informational and comparative manner for the clients using my web application. On one particular page of my web application, I need to combine data from 3 - 5 Oracle tables for display as an HTML table on the page. We are NOT currently using a framework (Apache Struts for instance) and we're not in a position to move this Java web application into one at this moment (I'm trying to get us there...). I am certainly not an architect, but I see one of two ways that I can effectively build this page (I know there are other ways, but these seem like they would be good ones...): 1. Create an Oracle Materialized View that represents what the HTML table should look like and then create a POJO based on the View that I can then integrate into my JSP. 2. Create POJOs that represent the Oracle tables themselves and then create another POJO that is the View used for the HTML table and then integrate that POJO into my JSP. To me, it seems the Materialized View would possibly offer quicker results which is always what we strive for in web applications. But, if I just create 12 POJOs that represent the Oracle tables and then build POJO Views off of those, I have the advantage of keeping all the code in one place for this and possibility for creating any number of different views and reusable components in my web application. Any thoughts on which one might be the better route? Or, maybe you know of an even better one?
