  • Oracle WebLogic Server and Oracle Database: A Robust Infrastructure for your Applications

    - by Ruma Sanyal
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 It has been said that a chain is as strong as its weakest link. Well, this is also true for your application infrastructure. Not only are the various components that constitute your infrastructure, like database and application server critical, the integration between these things [whether coming out of the box from your vendor or done in-house] is paramount. Imagine your database being down and your application server not knowing about it and as a result your application waiting indefinitely for a database response – not a great situation if high availability is critical to your application. Or one of your database nodes is very busy, but your application server doesn’t have the intelligence to decipher that – it keeps pinging the busy node when it can in fact get a response from another idle node much faster. This is what Oracle WebLogic and Database integration provides: Intelligent integration out of the box. Tight integration between Oracle WebLogic and Database makes your infrastructure robust enough that not only does each of your infrastructure component provide you with improved RASP [reliability availability, scalability, and performance] but these components work together to offer improved performance & availability, better resource sharing, inherent scalability, ease of configuration and automated management for your entire infrastructure. Oracle WebLogic Server is the only application server with this degree of integration to Oracle Database. With Oracle WebLogic Server 11g, we introduced Active GridLink for Real Application Clusters (RAC). In conjunction with Oracle Database, this powerful software technology simplifies management, increases availability, and ensures fast connection failover with runtime connection, load balancing and affinity capabilities. With the release of Oracle Database 12c this summer, even tighter integration between Oracle WebLogic Server 12c (12.1.2) and Oracle Database 12c has been achieved and this further optimizes the integration for a global cloud environment. Read about these capabilities in detail in the Oracle WebLogic-Database Integration Whitepaper. Get in depth ‘how-to’ details from this YouTube video on the topic from our resident expert, Monica Roccelli. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • IPgallery banks on Solaris SPARC

    - by Frederic Pariente
    IPgallery is a global supplier of converged legacy and Next Generation Networks (NGN) products and solutions, including: core network components and cloud-based Value Added Services (VAS) for voice, video and data sessions. IPgallery enables network operators and service providers to offer advanced converged voice, chat, video/content services and rich unified social communications in a combined legacy (fixed/mobile), Over-the-Top (OTT) and Social Community (SC) environments for home and business customers. Technically speaking, this offer is a scalable and robust telco solution enabling operators to offer new services while controlling operating expenses (OPEX). In its solutions, IPgallery leverages the following Oracle components: Oracle Solaris, Netra T4 and SPARC T4 in order to provide a competitive and scalable solution without the price tag often associated with high-end systems. Oracle Solaris Binary Application Guarantee A unique feature of Oracle Solaris is the guaranteed binary compatibility between releases of the Solaris OS. That means, if a binary application runs on Solaris 2.6 or later, it will run on the latest release of Oracle Solaris.  IPgallery developed their application on Solaris 9 and Solaris 10 then runs it on Solaris 11, without any code modification or rebuild. The Solaris Binary Application Guarantee helps IPgallery protect their long-term investment in the development, training and maintenance of their applications. Oracle Solaris Image Packaging System (IPS) IPS is a new repository-based package management system that comes with Oracle Solaris 11. It provides a framework for complete software life-cycle management such as installation, upgrade and removal of software packages. IPgallery leverages this new packaging system in order to speed up and simplify software installation for the R&D and production environments. Notably, they use IPS to deliver Solaris Studio 12.3 packages as part of the rapid installation process of R&D environments, and during the production software deployment phase, they ensure software package integrity using the built-in verification feature. Solaris IPS thus improves IPgallery's time-to-market with a faster, more reliable software installation and deployment in production environments. Extreme Network Performance IPgallery saw a huge improvement in application performance both in CPU and I/O, when running on SPARC T4 architecture in compared to UltraSPARC T2 servers.  The same application (with the same activation environment) running on T2 consumes 40%-50% CPU, while it consumes only 10% of the CPU on T4. The testing environment comprised of: Softswitch (Call management), TappS (Telecom Application Server) and Billing Server running on same machine and initiating various services in capacity of 1000 CAPS (Call Attempts Per Second). In addition, tests showed a huge improvement in the performance of the TCP/IP stack, which reduces network layer processing and in the end Call Attempts latency. Finally, there is a huge improvement within the file system and disk I/O operations; they ran all tests with maximum logging capability and it didn't influence any benchmark values. "Due to the huge improvements in performance and capacity using the T4-1 architecture, IPgallery has engineered the solution with less hardware.  This means instead of deploying the solution on six T2-based machines, we will deploy on 2 redundant machines while utilizing Oracle Solaris Zones and Oracle VM for higher availability and virtualization" Shimon Lichter, VP R&D, IPgallery In conclusion, using the unique combination of Oracle Solaris and SPARC technologies, IPgallery is able to offer solutions with much lower TCO, while providing a higher level of service capacity, scalability and resiliency. This low-OPEX solution enables the operator, the end-customer, to deliver a high quality service while maintaining high profitability.

  • Get Exchange Online Mailbox Size in GB

    - by Brian Jackett
    As mentioned in my previous post I was recently working with a customer to get started with Exchange Online PowerShell commandlets.  In this post I wanted to follow up and show one example of a difference in output from commandlets in Exchange 2010 on-premises vs. Exchange Online.   Problem    The customer was interested in getting the size of mailboxes in GB.  For Exchange on-premises this is fairly easy.  A fellow PFE Gary Siepser wrote an article explaining how to accomplish this (click here).  Note that Gary’s script will not work when remoting from a local machine that doesn’t have the Exchange object model installed.  A similar type of scenario exists if you are executing PowerShell against Exchange Online.  The data type for TotalItemSize  being returned (ByteQuantifiedSize) exists in the Exchange namespace.  If the PowerShell session doesn’t have access to that namespace (or hasn’t loaded it) PowerShell works with an approximation of that data type.    The customer found a sample script on this TechNet article that they attempted to use (minor edits by me to fit on page and remove references to deleted item size.)   Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,StorageLimitStatus, ` @{name="TotalItemSize (MB)"; expression={[math]::Round( ` ($_.TotalItemSize.Split("(")[1].Split(" ")[0].Replace(",","")/1MB),2)}}, ` ItemCount | Sort "TotalItemSize (MB)" -Descending | Export-CSV "C:\My Documents\All Mailboxes.csv" -NoTypeInformation     The script is targeted to Exchange 2010 but fails for Exchange Online.  In Exchange Online when referencing the TotalItemSize property though it does not have a Split method which ultimately causes the script to fail.   Solution    A simple solution would be to add a call to the ToString method off of the TotalItemSize property (in bold on line 5 below).   Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,StorageLimitStatus, ` @{name="TotalItemSize (MB)"; expression={[math]::Round( ` ($_.TotalItemSize.ToString().Split("(")[1].Split(" ")[0].Replace(",","")/1MB),2)}}, ` ItemCount | Sort "TotalItemSize (MB)" -Descending | Export-CSV "C:\My Documents\All Mailboxes.csv" -NoTypeInformation      This fixes the script to run but the numerous string replacements and splits are an eye sore to me.  I attempted to simplify the string manipulation with a regular expression (more info on regular expressions in PowerShell click here).  The result is a workable script that does one nice feature of adding a new member to the mailbox statistics called TotalItemSizeInBytes.  With this member you can then convert into any byte level (KB, MB, GB, etc.) that suits your needs.  You can download the full version of this script below (includes commands to connect to Exchange Online session). $UserMailboxStats = Get-Mailbox -RecipientTypeDetails UserMailbox ` -ResultSize Unlimited | Get-MailboxStatistics $UserMailboxStats | Add-Member -MemberType ScriptProperty -Name TotalItemSizeInBytes ` -Value {$this.TotalItemSize -replace "(.*\()|,| [a-z]*\)", ""} $UserMailboxStats | Select-Object DisplayName,@{Name="TotalItemSize (GB)"; ` Expression={[math]::Round($_.TotalItemSizeInBytes/1GB,2)}}   Conclusion    Moving from on-premises to the cloud with PowerShell (and PowerShell remoting in general) can sometimes present some new challenges due to what you have access to.  This means that you must always test your code / scripts.  I still believe that not having to physically RDP to a server is a huge gain over some of the small hurdles you may encounter during the transition.  Scripting is the future of administration and makes you more valuable.  Hopefully this script and the concepts presented help you be a better admin / developer.         -Frog Out     Links The Get-MailboxStatistics Cmdlet, the TotalitemSize Property, and that pesky little “b” http://blogs.technet.com/b/gary/archive/2010/02/20/the-get-mailboxstatistics-cmdlet-the-totalitemsize-property-and-that-pesky-little-b.aspx   View Mailbox Sizes and Mailbox Quotas Using Windows PowerShell http://technet.microsoft.com/en-us/exchangelabshelp/gg576861#ViewAllMailboxes   Regular Expressions with Windows PowerShell http://www.regular-expressions.info/powershell.html   “I don’t always test my code…” image http://blogs.pinkelephant.com/images/uploads/conferences/I-dont-always-test-my-code-But-when-I-do-I-do-it-in-production.jpg   The One Thing: Brian Jackett and SharePoint 2010 http://www.youtube.com/watch?v=Sg_h66HMP9o

    Hurricane Sandy Edition Power outages in the Cleveland area made it impossible to publish posts on Tuesday and Wednesday. In my neighborhood most are still without power. The sound of howling winds that dominated on Monday and Tuesday has been replaced by the sound of of portable generators. My internet connection was restored only after AT&T U-Verse crewmen hooked up a portable generator to power the relay station up the street. Bear in mind that Cleveland is 500 miles from the Atlantic coast. Mobile Development Platform Strategy Chart: ADF Mobile, WebCenter Sites, Portal, Content and Social "Unlike desktop web focused efforts, the world of mobile has undergone change at a feverish pace," says social enterprise expert John Brunswick. His extensive post charts various resources that will help you keep up. ADF Essentials - The Bare Necessities | Floyd Teter The experiment is over... And now Oracle ACE Director Floyd Teter shares his impressions after spending some time with Oracle ADF Essentials, the free version of Oracle ADF. Expanding the Oracle Enterprise Repository with functional documentation Capgemini middleware specialist Marc Kuijpers shares information on how Oracle Enterprise Repository can be configured "to contain functional assets, i.e. functional designs, use cases and a logical data model" to aid in SOA governance efforts. A review of Oracle SOA Suite 11g Administrator’s Handbook | RedStack "More so than any other single piece of content that I have seen on the topic, it provides the information that a SOA administrator needs to know in order to successfully configure, manage, monitor, troubleshoot and backup an Oracle SOA environment." So says Oracle Fusion Middleware A-Team solution architect Mark Nelson of Oracle SOA Suite 11g Administrator’s Handbook, by Ahmed Aboulnaga and Arun Pareek. Eating our own dog food – Oracle’s internal deployment of Oracle IDM Oracle Fusion Middleware A-Team member Brian Eidelman recommends the recent podcast on Oracle’s internal deployment of Oracle OAM and OID. "This was a big project that involved migrating a bunch of critical, high volume applications to leverage OAM and OID," says Eidelman. "So I suggest you tune in to see and hear more about how we deploy our own software."

  • Log Debug Messages without Debug Serial on Shipped Device

    - by Kate Moss' Open Space
    Debug message is one of the ancient but useful way for problem resolving. Message is redirected to PB if KITL is enabled otherwise it goes to default debug port, usually a serial port on most of the platform but it really depends on how OEMWriteDebugString and OEMWriteDebugByte are implemented. For many reasons, we don't want to have a debug serial port, for example, we don't have enough spare serial ports and it can affect the performance. So some of the BSP designers decide to dump the messages into other media, could be a log file, shared memory or any solution that is suitable for the need. In CE 5.0 and previous, OAL and Kernel are linked into one binaries; in the other word, you can use whatever function in kernel, such as SC_CreateFileW to access filesystem in OAL, even this is strongly not recommended. But since the OAL is being a standalone executable in CE 6.0, we no longer can use this back door but only interface exported in NKGlobal which just provides enough for OAL but no more. Accessing filesystem or using sync object to communicate to other drivers or application is even not an option. Sounds like the kernel lock itself up; of course, OAL is in kernel space, you can still do whatever you want to hack into kernel, but once again, it is not only make it a dirty solution but also fragile. So isn't there an elegant solution? Let's see how a debug message print out. In private\winceos\COREOS\nk\kernel\printf.c, the OutputDebugStringW is the one for pumping out the messages; most of the code is for error handling and serialization but what really interesting is the following code piece     if (g_cInterruptsOff) {         OEMWriteDebugString ((unsigned short *)str);     } else {         g_pNKGlobal->pfnWriteDebugString ((unsigned short *)str);     }     CELOG_OutputDebugString(dwActvProcId, dwCurThId, str); It outputs the message to default debug output (is redirected to KITL when available) or OAL when needed but note that highlight part, it also invokes CELOG_OutputDebugString. Follow the thread to private\winceos\COREOS\nk\logger\CeLogInstrumentation.c, this function dump whatever input to CELOG. So whatever the debug message is we always got a clone in CELOG. General speaking, all of the debug message is logged to CELOG already, so what you need to do is using celogflush.exe with CELZONE_DEBUG zone, and then viewing the data using the by Readlog tool. Here are some information about these tools CELOG - http://msdn.microsoft.com/en-us/library/ee479818.aspx READLOG - http://msdn.microsoft.com/en-us/library/ee481220.aspx Also for advanced reader, I encourage you to dig into private\winceos\COREOS\nk\celog\celogdll, the source of CELOG.DLL and use it as a starting point to create a more lightweight debug message logger for your own device!

    I have been working on .Net platform for 2 years and right now I am working on DevExpress controls for 6 months. All these control have client-side Events which are under some ClientScript nameSpace of particular control, Which specify ClientInstanceName, methods and properties accessible at client side. For example Button1 is ClientInstanceName and Button1.Text is a property, with methods like these: Button1.SetValue(); Button1.GetValue(); In ASP.Net Controls, buttons have the ClientClick event that fires before the Server Side Click event. I have inspected and goggled to extend client side functionality in asp.net controls. For example: create a ClientInstanceName property for controls or CheckedChanged event for CheckBox / RadioButton control. I have tried using these MSDN articles: Injecting Client-Side Script from an ASP.NET Server Control Working with Client-Side Script I got much information and ideas from these articles on how to implement/extend these. All are working in the client side. protected override void AddAttributesToRender(HtmlTextWriter writer) { base.AddAttributesToRender(writer); string script = @"return confirm(""%%POPUP_MESSAGE%%"");"; script = script.Replace("%%POPUP_MESSAGE%%", this.PopupMessage.Replace("\"", "\\\"")); writer.AddAttribute(HtmlTextWriterAttribute.Onclick, script); } Here It is just setting up attribute to the button. but all client side interaction no control from server. Here is that I want to know: How can I implement such functionality to create methods, properties etc. on client side. For example I am creating a PopControl as in the above code snippet same behavior as like Ajax ModalPopupExtender That have OK Button related properties. Ajax Controls can be directed to perform work from server side code e.g. Popup1.show(); How can I do this with such client enabled controls implemented controls as windows do? I am learning creation of Ajax Controls but I do not want to use ScriptManager or depend on another control. Just some extension to standard controls. I am expecting for ideas and implementation methods for such functionality.

  • Visual Studio 2010 Best Practices

    - by Etienne Tremblay
    I’d like to thank Packt for providing me with a review version of Visual Studio 2010 Best Practices eBook. In fairness I also know the author Peter having seen him speak at DevTeach on many occasions.  I started by looking at the table of content to see what this book was about, knowing that “best practices” is a real misnomer I wanted to see what they were.  I really like the fact that he starts the book by really saying they are not really best practices but actually recommend practices.  As a Team Foundation Server user I found that chapter 2 was more for the open source crowd and I really skimmed it.  The portion on Branching was well documented, although I’m not a fan of the testing branch myself, but the rest was right on. The section on merge remote changes (bring the outside to you) paradigm is really important and was touched on. Chapter 3 has good solid practices on low level constructs like generics and exceptions. Chapter 4 dives into architectural practices like decoupling, distributed architecture and data based architecture.  DTOs and ORMs are touched on briefly as is NoSQL. Chapter 5 is about deployment and is really a great primer on all the “packaging” technologies like Visual Studio Setup and Deployment (depreciated in 2012), Click Once and WIX the major player outside of commercial solutions.  This is a nice section on how to move from VSSD to WIX this is going to be important in the coming years due to the fact that VS 2012 doesn’t support VSSD. In chapter 6 we dive into automated testing practices, including test coverage, mocking, TDD, SpecDD and Continuous Testing.  Peter covers all those concepts really nicely albeit succinctly. Being a book on recommended practices I find this is really good. I really enjoyed chapter 7 that gave me a lot of great tips to enhance my Visual Studio “experience”.  Tips on organizing projects where good.  Also even though I knew about configurations I like that he put that in there so you can move all your settings to another machine, a lot of people don’t know about that. Quick find and Resharper are also briefly covered.  He touches on macros (depreciated in 2012).  Finally he touches on Continuous Integration a very important concept in today’s ALM landscape. Chapter 8 is all about Parallelization, threads, Async, division of labor, reactive extensions.  All those concepts are touched on and again generalized approaches to those modern problems are giving.       Chapter 9 goes into distributed apps, the most used and accepted practice in the industry for .NET projects the chapter tackles concepts like Scalability, Messaging and Cloud (the flavor of the month of distributed apps, although I think this will stick ;-)).  He also looks a protocols TCP/UDP and how to debug distributed apps.  He touches on logging and health monitoring. Chapter 10 tackles recommended practices for web services starting with implementing WCF services, which goes into all sort of goodness like how to host in IIS or self-host.  How to manual test WCF services, also a section on authentication and authorization.  ASP.NET Web services are also touched on in that chapter All in all a good read, nice tips and accepted practices.  I like the conciseness of the subjects and Peter touches on a lot of things in this book and uses a lot of the current technologies flavors to explain the concepts.   Cheers, ET

    - by ACShorten
    The Oracle Utilities Application Framework V4.2.0.0.0 has been released with Oracle Utilities Customer Care And Billing V2.4. This release includes new functionality and updates to existing functionality and will be progressively released across the Oracle Utilities applications. The release is quite substantial with lots of new and exciting changes. The release notes shipped with the product includes a summary of the changes implemented in V4.2.0.0.0. They include the following: Configuration Migration Assistant (CMA) - A new data management capability to allow you to export and import Configuration Data from one environment to another with support for Approval/Rejection of individual changes. Database Connection Tagging - Additional tags have been added to the database connection to allow database administrators, Oracle Enterprise Manager and other Oracle technology the ability to monitor and use individual database connection information. Native Support for Oracle WebLogic - In the past the Oracle Utilities Application Framework used Oracle WebLogic in embedded mode, and now, to support advanced configuration and the ExaLogic platform, we are adding Native Support for Oracle WebLogic as configuration option. Native Web Services Support - In the past the Oracle Utilities Application Framework supplied a servlet to handle Web Services calls and now we offer an alternative to use the native Web Services capability of Oracle WebLogic. This allows for enhanced clustering, a greater level of Web Service standards support, enchanced security options and the ability to use the Web Services management capabilities in Oracle WebLogic to implement higher levels of management including defining additional security rules to control access to individual Web Services. XML Data Type Support - Oracle Utilities Application Framework now allows implementors to define XML Data types used in Oracle in the definition of custom objects to take advantage of XQuery and other XML features. Fuzzy Operator Support - Oracle Utilities Application Framework supports the use of the fuzzy operator in conjunction with Oracle Text to take advantage of the fuzzy searching capabilities within the database. Global Batch View - A new JMX based API has been implemented to allow JSR120 compliant consoles the ability to view batch execution across all threadpools in the Coherence based Named Cache Cluster. Portal Personalization - It is now possible to store the runtime customizations of query zones such as preferred sorting, field order and filters to reuse as personal preferences each time that zone is used. These are just the major changes and there are quite a few more that have been delivered (and more to come in the service packs!!). Over the next few weeks we will be publishing new whitepapers and new entries in this blog outlining new facilities that you want to take advantage of.

  • A Slice of Raspberry Pi

    - by Phil Factor
    Guest editorial for the ITPro/SysAdmin newsletter The Raspberry Pi Foundation has done a superb design job on their new $35 network-enabled Linux computer. This tiny machine, incorporating an ARM processor on a Broadcom BCM2835 multimedia chip, aims to put the fun back into learning computing. The public response has been overwhelmingly positive.Note that aim: "…to put the fun back". Education in Information Technology is in dire straits. It always has been, but seems to have deteriorated further still, even in the face of improved provision of equipment.In many countries, the government controls the curriculum. It predicted a shortage in office-based IT skills, and so geared the ICT curriculum toward mind-numbing training in word-processing and spreadsheet skills. Instead, the shortage has turned out to be in people with an engineering-mindset, who can solve problems with whatever technologies are available and learn new techniques quickly, in a rapidly-changing field.In retrospect, the assumption that specific training was required rather than an education was an idiotic response to the arrival of mainstream information technology. As a result, ICT became a disaster area, which discouraged a generation of youngsters from a career in IT, and thereby led directly to the shortage of people with the skills that are required to exploit the potential of Information Technology..Raspberry Pi aims to reverse the trend. This is a rig that is geared to fast graphics in high resolution. It is no toy. It should be a superb games machine. However, the use of Fedora, Debian, or Arch Linux ARM shows the more serious educational intent behind the Foundation's work. It looks like it will even do some office work too!So, get hold of any power supply that provides a 5VDC source at the required 700mA; an old Blackberry charger will do or, alternatively, it will run off four AA cells. You'll need a USB hub to support the mouse and keyboard, and maybe a hard drive. You'll want a DVI monitor (with audio out) or TV (sound and video). You'll also need to be able to cope with wired Ethernet 10/100, if you want networking.With this lot assembled, stick the paraphernalia on the back of the HDTV with Blu Tack, get a nice keyboard, and you have a classy Linux-based home computer. The major cost is in the T.V and the keyboard. If you're not already writing software for this platform, then maybe, at a time when some countries are talking of orders in the millions, you should consider it.

  • Mixed Solaris 10 and 11 versions in logical domains on the same server

    - by jsavit
    One question that comes up frequently is whether you can mix Solaris 10 and Solaris 11 in different logical domains under Oracle VM Server for SPARC. The answer is yes depending only on the system software requirements for the underlying hardware platform. Different versions of Solaris 10 and 11 can exist side-by-side on the same server and can act as control, service, I/O or guest domains subject only to the minimum software levels documented in the System Requirements section of the Oracle VM Server for SPARC Release Notes. Here's an example just taken from a running system. First, here's the control domain, which is running Solaris 10. I've highlighted a guest running Solaris 11. # uname -a SunOS atl-sewr-24 5.10 Generic_147440-01 sun4v sparc SUNW,SPARC-Enterprise-T5220 # ldm -V Logical Domains Manager (v 2.1) Hypervisor control protocol v 1.7 Using Hypervisor MD v 1.3 System PROM: Hypervisor v. 1.10.0 @(#)Hypervisor 1.10.0 2011/04/27 16:19\015 # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- SP 16 4G 1.6% 120d 17h atl-sewr-pool-148 active -n---- 5001 8 2G 0.1% 119d 21h atl-sewr-pool-152 active -n---- 5000 8 4G 0.2% 112d 19h atl-sewr-pool-154 active -n---- 5002 8 2G 0.1% 120d 15h atl-sewr-pool-155 active -n---- 5003 16 2G 0.0% 26d 14h 30m This system is running Oracle VM Server 2.1 with a Solaris 10 control domain. Hmm, I should update this machine to 2.2 when I get a few free moments. Upgrading is very straightforward. Here's a display logging into the highlighted guest: Last login: Mon May 21 10:18:16 2012 from dhcp-adc-twvpn- Oracle Corporation SunOS 5.11 11.0 November 2011 sewr@atl-sewr-pool-152:~$ uname -a SunOS atl-sewr-pool-152 5.11 11.0 sun4v sparc SUNW,SPARC-Enterprise-T5220 sewr@atl-sewr-pool-152:~$ cat /etc/release Oracle Solaris 11 11/11 SPARC Copyright (c) 1983, 2011, Oracle and/or its affiliates. All rights reserved. Assembled 18 October 2011 sewr@atl-sewr-pool-152:~$ sudo virtinfo -ct Password: Domain role: LDoms guest Control domain: atl-sewr-24 sewr@atl-sewr-pool-152:~$ That's running the GA version of Solaris 11, so I probably should update that some time too. Note the use of the virtinfo -ct command that lets the guest get information about the hosting environment. Summary You can mix and match versions of Solaris in logical domains. All the different combinations work: Solaris 10 and/or Solaris 11 control and service domains with Solaris 10 and/or Solaris 11 guests. Mixing different guest OS levels on the same server is one of the traditional reasons for using virtual machines in the first place since virtual machines were invented some 40 years ago, used to run production and test systems in parallel while upgrading OS levels. This can easily be done with Oracle VM Server for SPARC (Logical Domains).

  • SQL Azure: Notes on Building a Shard Technology

    - by Herve Roggero
    In Chapter 10 of the book on SQL Azure (http://www.apress.com/book/view/9781430229612) I am co-authoring, I am digging deeper in what it takes to write a Shard. It's actually a pretty cool exercise, and I wanted to share some thoughts on how I am designing the technology. A Shard is a technology that spreads the load of database requests over multiple databases, as transparently as possible. The type of shard I am building is called a Vertical Partition Shard  (VPS). A VPS is a mechanism by which the data is stored in one or more databases behind the scenes, but your code has no idea at design time which data is in which database. It's like having a mini cloud for records instead of services. Imagine you have three SQL Azure databases that have the same schema (DB1, DB2 and DB3), you would like to issue a SELECT * FROM Users on all three databases, concatenate the results into a single resultset, and order by last name. Imagine you want to ensure your code doesn't need to change if you add a new database to the shard (DB4). Now imagine that you want to make sure all three databases are queried at the same time, in a multi-threaded manner so your code doesn't have to wait for three database calls sequentially. Then, imagine you would like to obtain a breadcrumb (in the form of a new, virtual column) that gives you a hint as to which database a record came from, so that you could update it if needed. Now imagine all that is done through the standard SqlClient library... and you have the Shard I am currently building. Here are some lessons learned and techniques I am using with this shard: Parellel Processing: Querying databases in parallel is not too hard using the Task Parallel Library; all you need is to lock your resources when needed Deleting/Updating Data: That's not too bad either as long as you have a breadcrumb. However it becomes more difficult if you need to update a single record and you don't know in which database it is. Inserting Data: I am using a round-robin approach in which each new insert request is directed to the next database in the shard. Not sure how to deal with Bulk Loads just yet... Shard Databases:  I use a static collection of SqlConnection objects which needs to be loaded once; from there on all the Shard commands use this collection Extension Methods: In order to make it look like the Shard commands are part of the SqlClient class I use extension methods. For example I added ExecuteShardQuery and ExecuteShardNonQuery methods to SqlClient. Exceptions: Capturing exceptions in a multi-threaded code is interesting... but I kept it simple for now. I am using the ConcurrentQueue to store my exceptions. Database GUID: Every database in the shard is given a GUID, which is calculated based on the connection string's values. DataTable. The Shard methods return a DataTable object which can be bound to objects.  I will be sharing the code soon as an open-source project in CodePlex. Please stay tuned on twitter to know when it will be available (@hroggero). Or check www.bluesyntax.net for updates on the shard. Thanks!

    - by Bob Rhubart
    The results are in... Listed below are the Top 10 most popular items shared via the OTN ArchBeat Facebook Page for the month of September 2012. The Real Architects of Los Angeles - OTN Architect Day - Oct 25 No gossip. No drama. No hair pulling. Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen. Oracle 11gR2 RAC on Software Defined Network (SDN) (OpenvSwitch, Floodlight, Beacon) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation. Process Oracle OER Events using a simple Web Service | Bob Webster Bob Webster's post "provides an example of a simple web service that processes Oracle Enterprise Repository (OER) Events. The service receives events from OER and utilizes the OER REX API to implement simple OER automations for selected event types." Understanding Oracle BI 11g Security vs Legacy Oracle BI 10g | Christian Screen "After conducting a large amount of Oracle BI 10g to Oracle BI 11g upgrades and after writing the Oracle BI 11g book,"says Oracle ACE Christian Screen, "I still continually get asked one of the most basic questions regarding security in Oracle BI 11g; How does it compare to Oracle BI 10g? The trail of questions typically goes on to what are the differences? And, how do we leverage our current Oracle BI 10g security table schema in Oracle BI 11g?" OIM-OAM-OAAM integration using TAP – Request Flow you must understand!! | Atul Kumar Atul Kumar's post addresses "key points and request flow that you must understand" when integrating three Oracle Identity Management product Oracle Identity Management, Oracle Access Management, and Oracle Adaptive Access Manager. Adding a runtime LOV for a taskflow parameter in WebCenter | Yannick Ongena Oracle ACE Yannick Ongena illustrates how to customize the parameters tab for a taskflow in WebCenter. Tips on Migrating from AquaLogic .NET Accelerator to WebCenter WSRP Producer for .NET | Scott Nelson "It has been a very winding path and this blog entry is intended to share both the lessons learned and relevant approaches that led to those learnings," says Scott Nelson. "Like most journeys of discovery, it was not a direct path, and there are notes to let you know when it is practical to skip a section if you are in a hurry to get from here to there." 15 Lessons from 15 Years as a Software Architect | Ingo Rammer In this presentation from the GOTO Conference in Copenhagen, Ingo Rammer shares 15 tips regarding people, complexity and technology that he learned doing software architecture for 15 years. WebCenter Content (WCC) Trace Sections | ECM Architect ECM Architect Kevin Smith shares a detailed technical post covering WebCenter Content (WCC) Trace Sections. Thought for the Day "Eventually everything connects - people, ideas, objects. The quality of the connections is the key to quality per se." — Charles Eames (June 17, 1907 – August 21, 1978) Source: SoftwareQuotes.com

  • Have Your Cake and Eat it Too: Industry Best Practices + Flexibility

    - by Oracle Accelerate for Midsize Companies
    By Richard Garraputa, VP of Sales & Marketing, brij Richard joined brij in 1996 after graduating from the University of North Carolina at Greensboro with degrees in Information Systems and Accounting. He directs brij’s overall strategies of both the business development and marketing departments. Companies looking for new ERP systems spend so much time comparing features and functions of software products but too often short change the value of their own processes.  Company managers I meet often claim that they are implementing a new ERP system so they can perform better and faster.  When asked how, the answer is often “by implementing best practices”.  But the term ‘best practices’ is frequently used to mean ‘doing things the way everyone else does them’ rather than a starting point or benchmark to build upon by adding your own value. Of course, implementing standardized processes across an enterprise is an important step in improving operational efficiencies.  But not all companies are alike.  Do you ever tell your customers “We are just like our competition and have no competitive differentiation”?  Probably not.  So why should the implementation of your business processes be just like your competitor’s?  Even within the same industry, companies differentiate themselves by leveraging their unique expertise and approach to business.  These unique aspects—the competitive differentiators that companies use to thrive in a crowded marketplace—can and should be supported by the implementation of business systems like ERP. Modern ERP systems like Oracle’s JD Edwards EnterpriseOne have a broad and deep functional footprint designed to integrate a company’s core operations.  But how can a company take advantage of this footprint without blowing up their implementation budget?  Some ERP vendors claim to solve this challenge by stating that their systems come pre-configured with ‘best practices’.  Too often what they are really saying is that you will have to abandon your key operational differentiators to fit a vendor’s template for your business—or extend your implementation and postpone the realization of any benefits. Thankfully for midsize companies, there is an alternative to the undesirable options of extended implementation projects or abandoning their competitive differentiators.  Oracle Accelerate Solutions speed the time it takes to implement JD Edwards EnterpriseOne solution based on your unique business characteristics, getting your new ERP system up and running faster without forcing your business to fit a cookie-cutter solution. We’ve been a JD Edwards implementation partner since 1986 and we now leverage Oracle Business Accelerators—cloud based rapid implementation tools built and maintained by Oracle. Oracle Business Accelerators deliver the benefits of embedded industry best practices without forcing every customer in to one set of processes like many template or “clone and go” approaches do. You retain the ability to reconfigure your applications—without customization—as your business changes. Wielded by Oracle partners with industry-specific domain expertise, Oracle Accelerate Solution implementations powered by Oracle Business Accelerators help automate the application configuration to fit your business better, faster. For example, on a recent project at a manufacturing company, the project manager told me that Oracle Business Accelerators helped get them to Conference Room Pilot 20% faster than with a traditional approach. Time savings equal cost savings. And if ‘better and faster’ is your goal for your business performance, shouldn’t it be the goal for your ERP implementation as well? Established in 1986, brij has been dedicated solely to helping its customers implement Oracle’s JD Edwards solutions and to maximize the value of those customers’ IT investments. They are a Gold level member in Oracle PartnerNetwork and an Oracle Accelerate Solution provider.

  • Connect to QuickBooks from PowerBuilder using RSSBus ADO.NET Data Provider

    - by dataintegration
    The RSSBus ADO.NET providers are easy-to-use, standards based controls that can be used from any platform or development technology that supports Microsoft .NET, including Sybase PowerBuilder. In this article we show how to use the RSSBus ADO.NET Provider for QuickBooks in PowerBuilder. A similar approach can be used from PowerBuilder with other RSSBus ADO.NET Data Providers to access data from Salesforce, SharePoint, Dynamics CRM, Google, OData, etc. In this article we will show how to create a basic PowerBuilder application that performs CRUD operations using the RSSBus ADO.NET Provider for QuickBooks. Step 1: Open PowerBuilder and create a new WPF Window Application solution. Step 2: Add all the Visual Controls needed for the connection properties. Step 3: Add the DataGrid control from the .NET controls. Step 4:Configure the columns of the DataGrid control as shown below. The column bindings will depend on the table. <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=ID}" Header="ID" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Name}" Header="Name" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid> Step 5:Add a reference to the RSSBus ADO.NET Provider for QuickBooks assembly. Step 6:Optional: Set the QBXML Version to 6. Some of the tables in QuickBooks require a later version of QuickBooks to support updates and deletes. Please check the help for details. Connect the DataGrid: Once the visual elements have been configured, developers can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of a SQL query: System.Data.RSSBus.QuickBooks.QuickBooksConnection conn conn = create System.Data.RSSBus.QuickBooks.QuickBooksConnection(connectionString) System.Data.RSSBus.QuickBooks.QuickBooksCommand comm comm = create System.Data.RSSBus.QuickBooks.QuickBooksCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.RSSBus.QuickBooks.QuickBooksDataAdapter dataAdapter dataAdapter = create System.Data.RSSBus.QuickBooks.QuickBooksDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView The code above can be used to bind data from any query (set this in command), to the DataGrid. The DataGrid should have the same columns as those returned from the SELECT statement. PowerBuilder Sample Project The included sample project includes the steps outlined in this article. You will also need the QuickBooks ADO.NET Data Provider to make the connection. You can download a free trial here.

  • Using Oracle BPM to Extend Oracle Applications

    - by Michelle Kimihira
    Author: Srikant Subramaniam, Senior Principal Product Manager, Oracle Fusion Middleware Customers often modify applications to meet their specific business needs - varying regulatory requirements, unique business processes, product mix transition, etc. Traditional implementation practices for such modifications are typically invasive in nature and introduce risk into projects, affect time-to-market and ease of use, and ultimately increase the costs of running and maintaining the applications. Another downside of these traditional implementation practices is that they literally cast the application in stone, making it difficult for end-users to tailor their individual work environments to meet specific needs, without getting IT involved. For many businesses, however, IT lacks the capacity to support such rapid business changes. As a result, adopting innovative solutions to change the economics of customization becomes an imperative rather than a choice. Let's look at a banking process in Siebel Financial Services and Oracle Policy Automation (OPA) using Oracle Business Process Management. This approach makes modifications simple, quick to implement and easy to maintain/upgrade. The process model is based on the Loan Origination Process Accelerator, i.e., a set of ready to deploy business solutions developed by Oracle using Business Process Management (BPM) 11g, containing customizable and extensible pre-built processes to fit specific customer requirements. This use case is a branch-based loan origination process. Origination includes a number of steps ranging from accepting a loan application, applicant identity and background verification (Know Your Customer), credit assessment, risk evaluation and the eventual disbursal of funds (or rejection of the application). We use BPM to model all of these individual tasks and integrate (via web services) with: Siebel Financial Services and (simulated) backend applications: FLEXCUBE for loan management, Background Verification and Credit Rating. The process flow starts in Siebel when a customer applies for loan, switches to OPA for eligibility verification and product recommendations, before handing it off to BPM for approvals. OPA Connector for Siebel simplifies integration with Siebel’s web services framework by saving directly into Siebel the results from the self-service interview. This combination of user input and product recommendation invokes the BPM process for loan origination. At the end of the approval process, we update Siebel and the financial app to complete the loop. We use BPM Process Spaces to display role-specific data via dashboards, including the ability to track the status of a given process (flow trace). Loan Underwriters have visibility into the product mix (loan categories), status of loan applications (count of approved/rejected/pending), volume and values of loans approved per processing center, processing times, requested vs. approved amount and other relevant business metrics. Summary Oracle recommends the use of Fusion Middleware as an extensions platform for applications. This approach makes modifications simple, quick to implement and easy to maintain/upgrade applications (by moving customizations away from applications to the process layer). It is also easier to manage processes that span multiple applications by using Oracle BPM.

  • PASS Summit 2011 &ndash; Part II

    - by Tara Kizer
    I arrived in Seattle last Monday afternoon to attend PASS Summit 2011.  I had really wanted to attend Gail Shaw’s (blog|twitter) and Grant Fritchey’s (blog|twitter) pre-conference seminar “All About Execution Plans” on Monday, but that would have meant flying out on Sunday which I couldn’t do.  On Tuesday, I attended Allan Hirt’s (blog|twitter) pre-conference seminar entitled “A Deep Dive into AlwaysOn: Failover Clustering and Availability Groups”.  Allan is a great speaker, and his seminar was packed with demos and information about AlwaysOn in SQL Server 2012.  Unfortunately, I have lost my notes from this seminar and the presentation materials are only available on the pre-con DVD.  Hmpf! On Wednesday, I attended Gail Shaw’s “Bad Plan! Sit!”, Andrew Kelly’s (blog|twitter) “SQL 2008 Query Statistics”, Dan Jones’ (blog|twitter) “Improving your PowerShell Productivity”, and Brent Ozar’s (blog|twitter) “BLITZ! The SQL – More One Hour SQL Server Takeovers”.  In Gail’s session, she went over how to fix bad plans and bad query patterns.  Update your stale statistics! How to fix bad plans Use local variables – optimizer can’t sniff it, so it’ll optimize for “average” value Use RECOMPILE (at the query or stored procedure level) – CPU hit OPTIMIZE FOR hint – most common value you’ll pass How to fix bad query patterns Don’t use them – ha! Catch-all queries Use dynamic SQL OPTION (RECOMPILE) Multiple execution paths Split into multiple stored procedures OPTION (RECOMPILE) Modifying parameter values Use local variables Split into outer and inner procedure OPTION (RECOMPILE) She also went into “last resort” and “very last resort” options, but those are risky unless you know what you are doing.  For the average Joe, she wouldn’t recommend these.  Examples are query hints and plan guides. While I enjoyed Andrew’s session, I didn’t take any notes as it was familiar material.  Andrew is a great speaker though, and I’d highly recommend attending his sessions in the future. Next up was Dan’s PowerShell session.  I need to look into profiles, manifests, function modules, and function import scripts more as I just didn’t quite grasp these concepts.  I am attending a PowerShell training class at the end of November, so maybe that’ll help clear it up.  I really enjoyed the Excel integration demo.  It was very cool watching PowerShell build the spreadsheet in real-time.  I must look into this more!  On a side note, I am jealous of Dan’s hair.  Fabulous hair! Brent’s session showed us how to quickly gather information about a server that you will be taking over database administration duties for.  He wrote a script to do a fast health check and then later wrapped it into a stored procedure, sp_Blitz.  I can’t wait to use this at my work even on systems where I’ve been the primary DBA for years, maybe there’s something I’ve overlooked.  We are using EPM to help standardize our environment and uncover problems, but sp_Blitz will definitely still help us out.  He even provides a cloud-based update feature, sp_BlitzUpdate, for sp_Blitz so you don’t have to constantly update it when he makes a change.  I think I’ll utilize his update code for some other challenges that we face at my work.
