  • Introducing the Oracle Linux Playground yum repo

    - by wcoekaer
    We just introduced a new yum repository/channel on http://public-yum.oracle.com called the playground channel. What we started doing is the following: When a new stable mainline kernel is released by Linus or GregKH, we internally build RPMs to test it and do some QA work around it to keep track of what's going on with the latest development kernels. It helps us understand how performance moves up or down and if there are issues, we try to help look into them and of course send that stuff back upstream. Many Linux users out there are interested in trying out the latest features but there are some potential barriers to do this. (1) in general, you are looking at an upstream development distribution, which means that everything changes both in userspace(random applications) and kernel. Projects like Fedora are very useful and someone that wants to just see how the entire distribution evolves with all the changes, this is a great way to be current. A drawback here, though, is that if you have applications that are not part of the distribution, there's a lot of manual work involved or they might just not work because the changes are too drastic. The introduction of systemd is a good example. (2) when you look at many of our customers, that are interested in our database products or applications, the starting point of having a supported/certified userspace/distribution, like Oracle Linux, is a much easier way to get your feet wet in seeing what new/future Linux kernel enhancements could do. This is where the playground channel comes into play. When you install Oracle Linux 6 (which anyone can download and use from http://edelivery.oracle.com/linux), grab the latest public yum repository file http://public-yum.oracle.com/public-yum-ol6.repo, put it in /etc/yum.repos.d and enable the playground repo : [ol6_playground_latest] name=Latest mainline stable kernel for Oracle Linux 6 ($basearch) - Unsupported baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/playground/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 Now, all you need to do : type yum update and you will be downloading the latest stable kernel which will install cleanly on Oracle Linux 6. Thus you end up with a stable Linux distribution where you can install all your software, and then download the latest stable kernel (at time of writing this is 3.6.7) without having to recompile a kernel, without having to jump through hoops. There is of course a big, very important disclaimer this is NOT for PRODUCTION use. We want to try and help make it easy for people that are interested, from a user perspective, where the Linux kernel is going and make it easy to install and use it and play around with new features. Without having to learn how to compile a kernel and without necessarily having to install a complete new distribution with all the changes top to bottom. So we don't or won't introduce any new userspace changes, this project really is around making it easy to try out the latest upstream Linux kernels in a very easy way on an environment that's stable and you can keep current, since all the latest errata for Oracle Linux 6 are published on the public yum repo as well. So one repository location for all your current changes and the upstream kernels. We hope that this will get more users to try out the latest kernel and report their findings. We are always interested in understanding stability and performance characteristics. As new features are going into the mainline kernel, that could potentially be interesting or useful for various products, we will try to point them out on our blogs and give an example on how something can be used so you can try it out for yourselves. Anyway, I hope people will find this useful and that it will help increase interested in upstream development beyond reading lkml by some of the more non-kernel-developer types.

  • Deploying Data Mining Models using Model Export and Import

    - by [email protected]
    In this post, we'll take a look at how Oracle Data Mining facilitates model deployment. After building and testing models, a next step is often putting your data mining model into a production system -- referred to as model deployment. The ability to move data mining model(s) easily into a production system can greatly speed model deployment, and reduce the overall cost. Since Oracle Data Mining provides models as first class database objects, models can be manipulated using familiar database techniques and technology. For example, one or more models can be exported to a flat file, similar to a database table dump file (.dmp). This file can be moved to a different instance of Oracle Database EE, and then imported. All methods for exporting and importing models are based on Oracle Data Pump technology and found in the DBMS_DATA_MINING package. Before performing the actual export or import, a directory object must be created. A directory object is a logical name in the database for a physical directory on the host computer. Read/write access to a directory object is necessary to access the host computer file system from within Oracle Database. For our example, we'll work in the DMUSER schema. First, DMUSER requires the privilege to create any directory. This is often granted through the sysdba account. grant create any directory to dmuser; Now, DMUSER can create the directory object specifying the path where the exported model file (.dmp) should be placed. In this case, on a linux machine, we have the directory /scratch/oracle. CREATE OR REPLACE DIRECTORY dmdir AS '/scratch/oracle'; If you aren't sure of the exact name of the model or models to export, you can find the list of models using the following query: select model_name from user_mining_models; There are several options when exporting models. We can export a single model, multiple models, or all models in a schema using the following procedure calls: BEGIN   DBMS_DATA_MINING.EXPORT_MODEL ('MY_MODEL.dmp','dmdir','name =''MY_DT_MODEL'''); END; BEGIN   DBMS_DATA_MINING.EXPORT_MODEL ('MY_MODELS.dmp','dmdir',              'name IN (''MY_DT_MODEL'',''MY_KM_MODEL'')'); END; BEGIN   DBMS_DATA_MINING.EXPORT_MODEL ('ALL_DMUSER_MODELS.dmp','dmdir'); END; A .dmp file can be imported into another schema or database using the following procedure call, for example: BEGIN   DBMS_DATA_MINING.IMPORT_MODEL('MY_MODELS.dmp', 'dmdir'); END; As with models from any data mining tool, when moving a model from one environment to another, care needs to be taken to ensure the transformations that prepare the data for model building are matched (with appropriate parameters and statistics) in the system where the model is deployed. Oracle Data Mining provides automatic data preparation (ADP) and embedded data preparation (EDP) to reduce, or possibly eliminate, the need to explicitly transport transformations with the model. In the case of ADP, ODM automatically prepares the data and includes the necessary transformations in the model itself. In the case of EDP, users can associate their own transformations with attributes of a model. These transformations are automatically applied when applying the model to data, i.e., scoring. Exporting and importing a model with ADP or EDP results in these transformations being immediately available with the model in the production system.

  • Beyond Cloud Technology, Enabling A More Agile and Responsive Organization

    - by sxkumar
    This is the second part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain”. In the first part,  I was sharing with you how a broad-based transformation makes cloud more than a technology initiative, I will describe in this section how it requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. People: Most IT organizations have a fairly complex organizational structure. There are different groups, managing different pieces of the puzzle, and yet, they don't always work together. Provisioning a new application therefore may require a request to float endlessly through system administrators, DBAs and middleware admin worlds – resulting in long delays and constant finger pointing.  Cloud users expect end-to-end automation - which requires these silos to be greatly simplified, if not completely eliminated.  Most customers I talk to acknowledge this problem but are quick to admit that such a transformation is hard. As hard as it may be, I am afraid that the status quo is no longer an option. Sticking to an organizational structure that was created ages back will not only impede cloud adoption,  it also risks making the IT skills increasingly irrelevant in a world that is rapidly moving towards converged applications and infrastructure.   Process: Most IT organizations today operate with a mindset that they must fully "control" access to any and all types of IT services. This in turn leads to people clinging on to outdated manual approval processes .  While requiring approvals for scarce resources makes sense, insisting that every single request must be manually approved defeats the very purpose of cloud. Not only this causes delays, thereby at least partially negating the agility benefits, it also results in gross inefficiency. In a cloud environment, self-service access should be governed by policies, quotas that the administrators can define upfront . For a cloud initiative to be successful, IT organizations MUST be ready to empower users by giving them real control rather than insisting on brokering every single interaction between users and the cloud resources. Technology: From a technology perspective, cloud is about consolidation, standardization and automation. A consolidated and standardized infrastructure helps increase utilization and reduces cost. Additionally, it  enables a much higher degree of automation - thereby providing users the required agility while minimizing operational costs.  Obviously, automation is the key to cloud. Unfortunately it hasn’t received as much attention within enterprises as it should have.  Many organizations are just now waking up to the criticality of automation and it still often gets relegated to back burner in favor of other "high priority" projects. However, it is important to understand that without the right type and level of automation, cloud will remain a distant dream for most enterprises. This in turn makes the choice of the cloud management software extremely critical.  For a cloud management software to be effective in an enterprise environment, it must meet the following qualifications: Broad and Deep Solution It should offer a broad and deep solution to enable the kind of broad-based transformation we are talking about.  Its footprint must cover physical and virtual systems, as well as infrastructure, database and application tiers. Too many enterprises choose to equate cloud with virtualization. While virtualization is a critical component of a cloud solution, it is just a component and not the whole solution. Similarly, too many people tend to equate cloud with Infrastructure-as-a-Service (IaaS). While it is perfectly reasonable to treat IaaS as a starting point, it is important to realize that it is just the first stepping stone - and on its own it can only provide limited business benefits. It is actually the higher level services, such as (application) platform and business applications, that will bring about a more meaningful transformation to your enterprise. Run and Manage Efficiently Your Mission Critical Applications It should not only be able to run your mission critical applications, it should do so better than before.  For enterprises, applications and data are the critical business assets  As such, if you are building a cloud platform that cannot run your ERP application, it isn't truly a "enterprise cloud".  Also, be wary of  vendors who try to sell you the idea that your applications must be written in a certain way to be able to run on the cloud. That is nothing but a bogus, self-serving argument. For the cloud to be meaningful to enterprises, it should adopt to your applications - and not the other way around.  Automated, Integrated Set of Cloud Management Capabilities At the root of many of the problems plaguing enterprise IT today is complexity. A complex maze of tools and technology, coupled with archaic  processes, results in an environment which is inflexible, inefficient and simply too hard to manage. Management tool consolidation, therefore, is key to the success of your cloud as tool proliferation adds to complexity, encourages compartmentalization and defeats the very purpose that you are building the cloud for. Decision makers ought to be extra cautious about vendors trying to sell them a "suite" of disparate and loosely integrated products as a cloud solution.  An effective enterprise cloud management solution needs to provide a tightly integrated set of capabilities for all aspects of cloud lifecycle management. A simple question to ask: will your environment be more or less complex after you implement your cloud? More often than not, the answer will surprise you.  At Oracle, we have understood these challenges and have been working hard to create cloud solutions that are relevant and meaningful for enterprises.  And we have been doing it for much longer than you may think. Oracle was one of the very first enterprise software companies to make our products available on the Amazon Cloud. As far back as in 2007, we created new cloud solutions such as Cloud Database Backup that are helping customers like Amazon save millions every year.  Our cloud solution portfolio is also the broadest and most deep in the industry  - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry.  And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies. I will dedicated the third and final part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain” to Oracle Cloud Technologies Building Blocks and how they mapped into our vision of Enterprise Cloud. Stay Tuned.

  • Oracle UPK Content Development Tool Settings

    - by [email protected]
    Oracle UPK Content Development tool settings: Before developing UPK content, your UPK Developer needs to be configured with certain standard settings to ensure the content will have a uniform look. To set the options: 1. Open the UPK Developer. 2. Click the Tools menu. 3. Click Options. After you configure the UPK Options, you can share these preferences with other content developers by exporting them to an .ops file. This is particularly useful in workgroup environments where multiple authors are working on the same content that requires consistent output regardless of who authored the content. (To learn more about Exporting/Importing Content Defaults refer to the Content Development.pdf guide that is delivered with the UPK Developer.) Here is a list of a few UPK Developer tool settings that Oracle UPK Content Developers use to develop UPK pre-built content: Screen resolution is set to 1024 x 768. See It mode frame delay is set to 5 seconds. Know It Required % is set to 70% and all three levels of remediation are selected. We opt to automatically record keyboard shortcuts. We use the default settings for the Bubble icon and Pointer position. Bubble color is yellow (Red = 255, Green = 255, Blue = 128). Bubble text is Verdana, Regular, 9 pt. ***Intro and end frame settings match the bubble settings Note: The Content Defaults String Input Settings will change based on which application (interface) you are recording against. For example here is a list of settings for different Oracle applications: • Agile - Microsoft Sans Serif, Regular, 8 • EBS - Microsoft Sans Serif, Regular, 10 • Hyperion - Microsoft Sans Serif, Regular, 8 • JDE E1 - Arial, Regular, 10 • PeopleSoft - Arial, Regular, 9 • Siebel - Arial, Regular, 8 Remember, it is recommended that you set the content defaults before you add documents and record content. When the content defaults are changed, existing documents are not affected and continue to use the defaults that were in effect when those documents were created. - Kathryn Lustenberger, Oracle UPK & Tutor Outbound Product Management

  • For Oracle's JD Edwards Customers--IT's Getting Better All The Time

    - by Oracle Accelerate for Midsize Companies
    By Jim Lein, Programs Management Sr. Principal, Oracle Midsize Programs. The annual JD Edwards Oracle Profit Magazine Special Edition was released this week. Look for the print copy in your mailbox or access the online version here. I entered the software industry when I joined JD Edwards in 1999. The next six years were a wild roller coaster ride for employees, partners, and--most unfortunately--for many of our customers. (Not entirely my fault BTW). In this Special Edition, I immediately gravitated to Aaron Lazenby's interview with Lyle Ekdahl, Group VP and General Manager of Oracle JD Edwards, "Better All The Time".  I met Lyle in 2003 when he joined PeopleSoft to guide JD Edwards' CRM development. He dropped by my cube (it was a double-wide cube, mind you) to explain his strategy. It was an intense first impression. Passionate, competent, personable. From my discussions with partners and customers, it is clear that for Oracle's JD Edwards customers it is getting better all the time. Now I've got that darn Beatle's song stuck in my head...

  • Suggestions for programming language and database for a high end database querying system (>50 milli

    - by mmdave
    These requirements are sketchy at the moment, but will appreciate any insights. We are exploring what would be required to build a system that can handle 50 database million queries a day - specifiically from the programming language and database choice Its not a typical website, but an API / database accessing through the internet. Speed is critical. The application will primarily receive these inputs (about a few kb each) and will have to address each of them via the database lookup. Only a few kb will be returned. The server will be run over https/ssl.

  • How to modernize an enormous legacy database?

    - by smayers81
    I have a question, just looking for suggestions here. So, my application is 'modernizing' a desktop application by converting it to the web, with an ICEFaces UI and server side written in Java. However, they are keeping around the same Oracle database, which at current count has about 700-900 tables and probably a billion total records in the tables. Some individual tables have 250 million rows, many have over 25 million. Needless to say, the database is not scaling well. As a result, the performance of the application is looking to be abysmal. The architects / decision makers-that-be have all either refused or are unwilling to restructure the persistence. So, basically we are putting a fresh coat of paint on a functional desktop application that currently serves most user needs and does so with relative ease and quick performance. I am having trouble sleeping at night thinking of how poorly this application is going to perform and how difficult it is going to be for everyday users to do their job. So, my question is, what options do I have to mitigate this impending disaster? Is there some type of intermediate layer I can put in between the database and the Java code to speed up performance while at the same time keeping the database structure intact? Caching is obviously an option, but I don't see that as being a cure-all. Is it possible to layer a NoSQL DB in between or something?

  • Oracle Social Network -The Social Glue for Enterprise Applications

    - by kellsey.ruppel
    by Peter Reiser  - Social Business Evangelist, Oracle WebCenter  Tom Petrocelli of Enterprise Strategy Group published a report recently, “Oracle Social Network: The Social Glue for Enterprise Applications”, on Oracle Social Network (OSN) and how traditional social products create social silos whereas OSN is the “social glue” for enterprise applications.  This report supports the point of Oracle’s Social Business Strategy to seamless integrate social capabilities into the main business processes. Quote from report: “Oracle has adopted the correct approach to creating a social layer and socially enabled applications. Oracle Social Network is not simply another enterprise social network product; it is a complete social layer for the enterprise application stack. This approach will serve Oracle users well in the future.” OSN allow to capture the related Conversations of a business process right where it’s happens – within the respective Business application.  Fusion CRM is an excellent example for this approach. Quote from report: “Oracle’s new software, Oracle Social Network, is an example of a solution to the silo problem. While Oracle fields a typical enterprise social network application with microblogging, file sharing, shared documents or wikis, and activity streams, the front-end application is only a small part of what Oracle Social Network does. Instead, Oracle Social Network is a platform that provides social features as a service to other enterprise applications. In effect, Oracle Social Network socially enables all of Oracle’s enterprise applications—all enterprise applications really—with not only the same features, but also the same conversations. As a result, the social conversations act as a conduit for inter-application communication and collaboration.” Source: ESG Research Report, Oracle Social Network: The Social Glue for Enterprise Applications, August 2012.

Ráadásul a felvásárlás óta a terméket sem lehetett megvásárolni, hiszen a merge után folyó fejlesztések még nem voltak készen. Január 11. óta azonban letötlheto az Oracle Database Firewall 5.0 telepítoje az Oracle edelivery oldaláról az Oracle Database Product Pack-en belül Linux x86 platformra. A Database Firewall az adatbázis védelem elso vonalának tekintheto. Valós idoben monitorozza az adatbázis aktivitását a hálózaton. SQL nyelvi elemzojével rendkívül pontosan képes detektálni a külso és belso támadásokat, a jogosultatlanul, támadó szándékkal végrehajtott tranzakciókat. Az SQL nyelvi elemzojének kifinomultsága lehetové teszi a szurés közel 100%-os pontosságát és megbízhatóságát, ami azért rendkívül fontos, mert nem elég minden támadó tranzakciót kiszurni, de fontos hogy a normál üzletmenetnek megfelelo tranzakciók közül egyet se szurjön, hiszen az is komoly üzleti károkat okozhat. Az adatbázis tuzfalról több részletet tudhat meg mindenki, aki regisztrál és ellátogat a január 27-i Oracle Security Summit rendezvényünkre, ahol a tervek szerint ismét Stuart Sharp tart majd eloadást, viszont ezúttal 1 órában sokkal több részletet tud megosztani a magyar ügyfelekkel és partnerekkel. A Database Firewall eloadást megelozoen egyébként én tartok egy kb. félórás áttekintést az Oracle Database biztonsági megoldásairól.

  • Oracle Social Network -The Social Glue for Enterprise Applications

    - by me
    Tom Petrocelli of Enterprise Strategy Group published a report recently, “Oracle Social Network: The Social Glue for Enterprise Applications”, on Oracle Social Network (OSN) and how traditional social products create social silos whereas OSN is the “social glue” for enterprise applications.  This report supports the point of Oracle’s Social Business Strategy to seamless integrate social capabilities into the main business processes. Quote from report: “Oracle has adopted the correct approach to creating a social layer and socially enabled applications. Oracle Social Network is not simply another enterprise social network product; it is a complete social layer for the enterprise application stack. This approach will serve Oracle users well in the future.” OSN allow to capture the related Conversations of a business process right where it’s happens – within the respective Business application.  Fusion CRM is an excellent example for this approach. Quote from report: “Oracle’s new software, Oracle Social Network, is an example of a solution to the silo problem. While Oracle fields a typical enterprise social network application with microblogging, file sharing, shared documents or wikis, and activity streams, the front-end application is only a small part of what Oracle Social Network does. Instead, Oracle Social Network is a platform that provides social features as a service to other enterprise applications. In effect, Oracle Social Network socially enables all of Oracle’s enterprise applications—all enterprise applications really—with not only the same features, but also the same conversations. As a result, the social conversations act as a conduit for inter-application communication and collaboration.” Source: ESG Research Report, Oracle Social Network: The Social Glue for Enterprise Applications, August 2012. cross-post from Oracle WebCenter blog

    Extinction isn’t exclusively a biological function; here’s a roundup of 11 sounds that have gone the way of the Dodo. Mental_Floss shares a roundup of 11 technological sounds lost to the ages, including rotary telephones–see above–flash cube snaps, television warmups, TV station sign offs, and more. One thing we’re shocked they didn’t include is the sound of an acoustic modem connection–but in fairness quite a few people are still using dial-up to connect to the Internet. 11 Sounds Your Kids Have Probably Never Heard [Mental_Floss via BoingBoing] Amazon’s New Kindle Fire Tablet: the How-To Geek Review HTG Explains: How Hackers Take Over Web Sites with SQL Injection / DDoS Use Your Android Phone to Comparison Shop: 4 Scanner Apps Reviewed

  • SQL SERVER – Auditing and Profiling Database Made Easy with SQL Audit and Comply

    - by Pinal Dave
    Do you like auditing your database, or can you think of about a million other things you’d rather do?  Unfortunately, auditing is incredibly important.  As with tax audits, it is important to audit databases to ensure they are following all the rules, but they are also important for troubleshooting and security. There are several ways to audit SQL Server.  There is manual auditing, which is going through your database “by hand,” and obviously takes a long time and is quite inefficient.  SQL Server also provides programs to help you audit your systems.  Different administrators will have different opinions about best practices and which tools to use, and each one will be perfected for certain systems and certain users. Today, though, I would like to talk about Apex SQL Audit.  It is an auditing tool that acts like “track changes” in a word processing document.  It will log what has changed on the database, who made the changes, and what effects these changes have had (i.e. what objects were affected down the line).  All this information is logged, and can be easily viewed or printed for easy access. One of the best features of Apex is that it is so customizable (and easy to use!).  First, start Apex.  Then you can connect to the database you would like to monitor. Once you select your database, you can select which table you want to audit. You can customize right down to the field you’d like to audit, and then select which types of actions you’d like tracked – insert, delete, or update.  Repeat these steps for every database you want monitored. To create the logs, choose “Create triggers” in the menu.  The script written here will be what logs each insert, delete, and update function.  Press F5 to execute.  All this tracking information will be stored in AUDIT_LOG_DATA and AUDIT_LOG_TRANSACTIONS tables.  View these tables using ApexSQL Audit reports. These transaction logs can be extremely detailed – especially on very busy servers, where every move it traced.  Reading them can be overwhelming, to say the least.  Apex has tried to make things easier for the average DBA, though. You can read these tracking logs in Apex, and it will display data and objects that affect your server – even things that were happening on your server before you installed Apex! To read these logs, open Apex, and connect to that database you want to audit. Go to the Transaction Logs tab, and add the logs you want to read. To narrow down what results you want to see, you can use the Filter tab to choose time, operation type, name, users, and more. Click Open, and you can see the results in a grid (as shown below).  You can export these results to CSV, HTML, XML or SQL files and save on the hard disk. One of the advantages is that since there are no triggers here, there are no other processes that will affect SQL Server performance.  Using this method is also how to view history from your database that occurred before Apex was installed.  This type of tracking does require storage space for the data sources, as the database must be fully running, and the transaction logs must exist (things not stored in the transactions logs will not be recoverable). Apex can also replace SQL Server Profiler and SQL Server Traces – which are much more complex and error-prone – with its ApexSQL Comply.  It can do fault tolerant auditing, centralized reporting, and “who saw what” information in an easy-to-use interface.  The tracking settings can be altered by the user, or the default options will provide solutions to the most common auditing problems. To get started: open ApexSQL Comply, and selected Database Filter Settings to choose which database you’d like to audit.  You can select which tracking you’re like in Operation Types – DML, DDL, queries executed, execute statements, and more.  To get started, click Start Auditing. After this, every action will be stored in the central repository database (ApexSQLCrd).  You can view the audit and create a report (or view the standard default report) using a wizard. You can see how easy it is to use ApexSQL Comply.  You can easily set audits, including the type and time, and create customized reports.  Remote users can easily access the reports through the user interface (available online, as well), and security concerns are all taken care of by the program.  Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQL Utility, T SQL, Technology

  • Oracle ACEs in the House

    - by Justin Kestelyn
    As is customary, the Oracle ACEs have invaded the Oracle Develop Conference agenda.Why? Because Oracle ACE-dom inherently is a stamp of not only expertise, but a unique ability to make that expertise useful to others. Plus, they're a group of "fine blokes" (UK. subjects, educate me: is that really a word?)Perhaps if you're not able to catch one of these sessions, you will be able to see the applicable ACE in action elsewhere, at a conference or user group meeting near you.
