  • Querying Networking Statistics: dlstat(1M)

    - by user12612042
    Oracle Solaris 11 took another big leap forward in networking technologies providing a reliable, secure and scalable infrastructure to meet the growing needs of today's datacenter implementations. Oracle Solaris 11 introduced a new and powerful network stack architecture, also known as Project Crossbow. From Solaris 11 onwards, we introduced a command line tool viz. dlstat(1M) to query network statistics. dlstat (for datalink statistics) is a statistics querying counterpart for dladm(1M) - the datalink administration tool. The tool is very easy to get started. Just type dlstat on a shell prompt on Solaris 11 (or later). For example,: # dlstat LINK IPKTS RBYTES OPKTS OBYTES net0 834.11K 145.91M 575.19K 104.24M net1 7.87K 2.04M 0 0 In this example, the system has two datalinks net0 and net1. The output columns denote input packets/bytes as well as output packets/bytes. The numbers are abbreviated in xxx.xxUnit format. However, one could get the actual counts by simply running dlstat -u R (R for raw): # dlstat -u R LINK IPKTS RBYTES OPKTS OBYTES net0 834271 145931244 575246 104242934 net1 7869 2036958 0 0 In addition, dlstat also supports various subcommands dlstat help The following subcommands are supported: Stats : show-aggr show-ether show-link show-phys show-bridge For more info, run: dlstat help {default|} I will only describe couple of interesting subcommands/options here. For a comprehensive description of all the dlstat subcommands refer dlstat's official manual . For NICs that support multiple rings (e.g. ixgbe), dlstat show-phys -r allows us to query per Rx ring statistics. For example: dlstat show-phys -r net4 LINK TYPE INDEX IPKTS RBYTES net4 rx 0 0 0 net4 rx 1 0 0 net4 rx 2 0 0 net4 rx 3 0 0 net4 rx 4 0 0 net4 rx 5 0 0 net4 rx 6 0 0 net4 rx 7 0 0 In this case, net4 is just a vanity name for an ixgbe datalink. This view is especially useful if one wants to look at the network traffic spread across all the available rings. Furthermore, any of the dlstat commands could be run with -i option to periodically query and display stats. For example, running dlstat show-phys -r net4 -i 5 will emit per Rx ring stats every 5 seconds. This is especially useful while analyzing a live system. Similarly, dlstat show-phys -t could be used to query per Tx ring stats. -r and -t could also be combined as dlstat show-phys -rt to query both Rx as well as Tx stats at the same time. Finally, there is also a quick way to dump ALL the stats. Just run dlstat -A. You probably want to redirect this output to a file because you are going to get a whole load of stats :-).

  • Ask the Readers: Do You Prefer Computers, Game Consoles, or Other Devices for Your Gaming Needs?

    - by Asian Angel
    Nearly everyone who has access to a computer will play games on it at some point, but many people also use a separate game platform as well. What we would like to know this week is if you prefer using a computer, game consoles, or other devices for your gaming needs. Photo of Faith and Kate Connors from Mirror’s Edge by Tamahikari Tammas. Video games are a perfect way to relax and have fun at home (or at work if you can sneak in some game time!). The increasing variety of devices available with each passing year are making it easier to have access to a gaming platform to suit your needs or “darkest gaming desires”. For many people their computers are the perfect platform…they can play Flash-based games in their browsers, use the default set of games that come with their system, and install any extras that catch their eyes. The added benefit is that when game time is over they can drop right into their browsing, e-mail, personal projects, or work without having to switch hardware. The convenience of the “all-in-one” platform is certainly appealing! Perhaps you prefer to use your computer for other activities outside of gaming and own one or more separate game consoles. You might have chosen an Xbox, Playstation, or Nintendo for example. Maybe a hand-held is preferable for its’ size and portability. Then there are mobile phones and the iPad… With so many options it may feel hard to choose the right platform(s) without a good bit of research regarding display, availability of games for a particular platform, how long before the platform starts to become “obsolete”, etc. What we would like to know this week is which gaming platform you prefer. Is there only one that you choose to use or do you use multiple platforms for gaming? Is there a particular reason such as convenience for your choices? You may even be keeping an older platform around just for a certain game (or games) made for it. Are there any recommendations or advice that you would like to share with your fellow readers?

  • The Minimalist Approach to Content Governance - Retire Phase

    - by Kellsey Ruppel
     Originally posted by John Brunswick. Good news - the Retire Phase is actually more fun than the Manage Phase. During the Retire Phase our content management team should not have to track down content creators if the Request Phase of this process was completed successfully. The ownership meta data, success criteria and time stamp that was applied to the original content submission will help to manage content at the end of the content life cycle. The Retire Phase will provide the opportunity for us to prune irrelevant content items through archiving or deletion, keeping the content system clear of irrelevant information, streamlining users ability to browse and search for content.   1. Act on Metrics Established during the Request Phase Why - Some information is only relevant for a given amount of time. In Content Platform Migration Strategy - Artifacts vs Perishable Content we examined two content types - Artifacts and Perishable content. Understanding the differences between Artifacts and Perishable content will allow us to explicitly respect their various lifespans. Additionally, some content may have been part of a project that failed to meet the success criteria outlined in the Request Phase. Any content that did not meet the metrics outlined in the Request Phase should be considered for deletion. How - Thankfully by adhering to to The Minimalist Approach to Content Governance our content should have some level of meta data associated with it that will allow us to quickly sort and understand how to deal with it. Content Management Systems like Oracle's Universal Content Management (UCM) natively allow you to create and save advanced searches that can use content meta data like folders, author, expiration date, security settings and custom meta data to pull back listings of content for examination. Additionally, analytics are available for all content items that allow us to determine if the usage is meeting success criteria that may have been previously outlined during the request phase. The lists that are produced from these approaches can be quickly reviewed for each project with the content owners and based on the nature of the content and success criteria undergo archiving or deletion. Impact - Retiring content that is no longer relevant will allow end users to have fast and relevant access to information across your enterprise. As we mentioned in our first post in this series - it is easy to quickly start producing content, but the challenge is ensuring that the environment is easy to navigate and use on the third week and during the third year. The light level of effort that was placed into the Request Phase of this process will set us up to keep content clean and relevant for a long time to come. With an up-to-date content repository users will be able to quickly find access to the information that is critical to their work processes. You might not get a holiday named in your honor managing the content system, but will appreciate their quick access to quality information.

  • Adding AjaxOnly Filter in ASP.NET Web API

    - by imran_ku07
            Introduction:                     Currently, ASP.NET MVC 4, ASP.NET Web API and ASP.NET Single Page Application are the hottest topics in ASP.NET community. Specifically, lot of developers loving the inclusion of ASP.NET Web API in ASP.NET MVC. ASP.NET Web API makes it very simple to build HTTP RESTful services, which can be easily consumed from desktop/mobile browsers, silverlight/flash applications and many different types of clients. Client side Ajax may be a very important consumer for various service providers. Sometimes, some HTTP service providers may need some(or all) of thier services can only be accessed from Ajax. In this article, I will show you how to implement AjaxOnly filter in ASP.NET Web API application.         Description:                     First of all you need to create a new ASP.NET MVC 4(Web API) application. Then, create a new AjaxOnly.cs file and add the following lines in this file, public class AjaxOnlyAttribute : System.Web.Http.Filters.ActionFilterAttribute { public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext) { var request = actionContext.Request; var headers = request.Headers; if (!headers.Contains("X-Requested-With") || headers.GetValues("X-Requested-With").FirstOrDefault() != "XMLHttpRequest") actionContext.Response = request.CreateResponse(HttpStatusCode.NotFound); } }                     This is an action filter which simply checks X-Requested-With header in request with value XMLHttpRequest. If X-Requested-With header is not presant in request or this header value is not XMLHttpRequest then the filter will return 404(NotFound) response to the client.                      Now just register this filter, [AjaxOnly] public string GET(string input)                     You can also register this filter globally, if your Web API application is only targeted for Ajax consumer.         Summary:                       ASP.NET WEB API provide a framework for building RESTful services. Sometimes, you may need your certain API services can only be accessed from Ajax. In this article, I showed you how to add AjaxOnly action filter in ASP.NET Web API. Hopefully you will enjoy this article too.

  • Debugging OWB generated SAP ABAP code executed through RFC

    - by Anil Menon
    Within OWB if you need to execute ABAP code using RFC you will have to use the SAP Function Module RFC_ABAP_INSTALL_AND_RUN. This function module is specified during the creation of the SAP source location. Usually in a Production environment a copy of this function module is used due to security restrictions. When you execute the mapping by using this Function Module you can’t see the actual ABAP code that is passed on to the SAP system. In case you want to take a look at the code that will be executed on the SAP system you need to use a custom Function Module in SAP. The easiest way to do this is to make a copy of the Function Module RFC_ABAP_INSTALL_AND_RUN and call it say Z_TEST_FM. Then edit the code of the Function Module in SAP as below FUNCTION Z_TEST_FM . DATA: BEGIN OF listobj OCCURS 20. INCLUDE STRUCTURE abaplist. DATA: END OF listobj. DATA: begin_of_line(72). DATA: line_end_char(1). DATA: line_length type I. DATA: lin(72). loop at program. append program-line to WRITES. endloop. ENDFUNCTION. Within OWB edit the SAP Location and use Z_TEST_FM as the “Execution Function Module” instead of  RFC_ABAP_INSTALL_AND_RUN. Then register this location. The Mapping you want to debug will have to be deployed. After deployment you can right click the mapping and click on “Start”.   After clicking start the “Input Parameters” screen will be displayed. You can make changes here if you need to. Check that the parameter BACKGROUND is set to “TRUE”. After Clicking “OK” the log for the execution will be displayed. The execution of Mappings will always fail when you use the above function module. Clicking on the icon “I” (information) the ABAP code will be displayed.   The ABAP code displayed is the code that is passed through the Function Module. You can also find the code by going through the log files on the server which hosts the OWB repository. The logs will be located under <OWB_HOME>/owb/log. Patch #12951045 is recommended while using the SAP Connector with OWB 11.2.0.2. For recommended patches for other releases please check with Oracle Support at http://support.oracle.com

  • ASP.NET MVC localization DisplayNameAttribute alternatives: a better way

    - by Brian Schroer
    In my last post, I talked bout creating a custom class inheriting from System.ComponentModel.DisplayNameAttribute to retrieve display names from resource files: [LocalizedDisplayName("RememberMe")] public bool RememberMe { get; set; } That’s a lot of work to put an attribute on all of my model properties though. It would be nice if I could intercept the ASP.NET MVC code that analyzes the model metadata to retrieve display names to make it automatically get localized text from my resource files. That way, I could just set up resource file entries where the keys are the property names, and not have to put attributes on all of my properties. That’s done by creating a custom class inheriting from System.Web.Mvc.DataAnnotationsModelMetadataProvider: 1: public class LocalizedDataAnnotationsModelMetadataProvider : 2: DataAnnotationsModelMetadataProvider 3: { 4: protected override ModelMetadata CreateMetadata( 5: IEnumerable<Attribute> attributes, 6: Type containerType, 7: Func<object> modelAccessor, 8: Type modelType, 9: string propertyName) 10: { 11: var meta = base.CreateMetadata 12: (attributes, containerType, modelAccessor, modelType, propertyName); 13:   14: if (string.IsNullOrEmpty(propertyName)) 15: return meta; 16:   17: if (meta.DisplayName == null) 18: GetLocalizedDisplayName(meta, propertyName); 19:   20: if (string.IsNullOrEmpty(meta.DisplayName)) 21: meta.DisplayName = string.Format("[[{0}]]", propertyName); 22:   23: return meta; 24: } 25:   26: private static void GetLocalizedDisplayName(ModelMetadata meta, string propertyName) 27: { 28: ResourceManager resourceManager = MyResource.ResourceManager; 29: CultureInfo culture = Thread.CurrentThread.CurrentUICulture; 30:   31: meta.DisplayName = resourceManager.GetString(propertyName, culture); 32: } 33: } Line 11 calls the base CreateMetadata method. Line 17 checks whether the metadata DisplayName property has already been populated by a DisplayNameAttribute (or my LocalizedDisplayNameAttribute). If so, it respects that and doesn’t use my custom localized text lookup. The GetLocalizedDisplayName method checks for the property name as a resource file key. If found, it uses the localized text from the resource files. If the key is not found in the resource file, as with my LocalizedDisplayNameAttribute, I return a formatted string containing the property name (e.g. “[[RememberMe]]”) so I can tell by looking at my web pages which resource keys I haven’t defined yet. It’s hooked up with this code in the Application_Start method of Global.asax: ModelMetadataProviders.Current = new LocalizedDataAnnotationsModelMetadataProvider();

  • Secure an Application/Software by expiration with Date?

    - by JNL
    I have been working on some software application and I update them every 6 months. Currently, the way I track the date is by extracting the date from the system when the user installes the application, encrypt it and store it in a file locally. Whenever the application is started, it checks if 6 months have passed, then it works or it doesn't, in which case it shows an error message telling the user to update. I wonder whether there is a better way to do this. Any comments or suggestions would be highly appreciated

  • Announcing Oracle Enterprise Content Management Suite 11g

    - by [email protected]
    Today Oracle announced Oracle Enterprise Content Management Suite 11g. This is a major release for us, and reinforces our three key themes at Oracle: Complete New in this release - Oracle ECM Suite 11g is built on a single, unified repository. Every piece of content - documents, HTML pages, digital assets, scanned images - is stored and accessbile directly from the repository, whether you are working on websites, creating brand logos, processing accounts payable invoices, or running records and retention functions. It makes complete, end-to-end management of content possible, from the point it enters the organization, through its entire lifecycle. Also new in this release, the installation, access, monitoring and administration of Oracle ECM Suite 11g is centralized. As a complete system, organizations can lower the costs of training and usage by having a centralized source of information that is easily administered. As part of this new unified repository release, Oracle has released a benchmarking white paper that shows the extreme performance and scalability of Oracle ECM Suite. When tested on a two node UCM Server running on Sun Oracle DB Machine Half Rack Hardware with an Exadata storage server, Oracle ECM Suite 11g is able to ingest over 178 million documents per day. Open Oracle ECM Suite 11g is built on a service-oriented architecture. All functions are available through standards-based services calls in Web Services or Java. In this release Oracle unveils Open Web Content Management. Open Web Content Management is a revolutionary approach to web content management that decouples the content management process from the process of creating web applications. One piece of this approach is our one-click web content management. With one click, a web application builder can drag content services into their application, enabling their users to also edit content with just one click. Open Web Content Management is also open because it enables Web developers to add Web content management to new and existing JavaServer Pages (JSP), JavaServer Faces (JSF) and Oracle Application Development Framework (ADF) Faces applications Open content distribution - Oracle ECM Suite 11g offers flexible deployment options with a built-in smart cache so organizations can deliver Web sites or Web applications without requiring Oracle ECM Suite as part of the delivery system Integrated Oracle ECM Suite 11g also offers a series of next generation desktop integrations, providing integrations such as: New MS Office integration with menus to access managed content, insert managed links, and compare managed documents using standard MS Office reviewing tools Automatic identity tagging of documents on download - to help users understand which versions they are viewing and prevent duplicate content items in the content repository. New "smart productivity folders" to show a users workflow inbox, saved searches and checked out content directly from Windows Explorer Drag and drop metadata pop-ups Check in and check out for all file formats with any standard WebDAV server As part of Oracle's Enterprise Application Documents initiative, Oracle Content Management 11g also provides certified application integrations with solution templates You can read the press release here. You can see more assets at the launch center here. You can sign up for the announcement webinar and hear more about the new features here. You can read the benchmarking study here.

  • MSCC: Scripting - Administrator's­ toolbox of magic...

    Finally, we made it to have our April meetup - in May. The most obvious explanation is the increased amount of open source and IT activities that either the MSCC, the Linux User Group of Mauritius (LUGM), or the University of Mauritius Student's Computer Club is organising. It's absolutely incredible to see the recent hype of events here on the island. And I'm loving it! Unfortunately, we also had to deal with arranging for a location this time. It was kind of an odyssey as my requests (and phone calls) haven't been answered, even though I tried it several times - well, kind of disappointing and I have to look into that for future gatherings. In my opinion, it is essential that two parameters of a community meeting are fixed as early as possible: Location, and Date and time You can't just change one or both on the very last minute. Well, this time we had to do it due to unforeseen reasons, and I apologise to any MSCC member which couldn't make it to our April meetup. Okay, lesson learned but now back to the actual meetup report ... Shortly after the meeting I placed the following statement as my first impression: "Spontaneous and improvised :) No, seriously, Ish and Dan had well prepared presentations on shell scripting, mainly focused towards Bourne Again Shell (bash), and the pros and cons of scripting versus actually writing something in a decent programming language. I thought that I could cut myself out of the equation but the demand for information about PowerShell was higher than expected..." Well, it turned out that the interest in Windows PowerShell was high, as I even got a couple of questions on it via social media networks during the evening. I also like to mention that the number of attendees went back to what I would call a "standard" number of participation. This time there were 12 craftsmen, but again a good number of First Timers. Reactions of other attendees Here are some impressions and feedback from our participants: "Enjoyed the bash and powershell (linux / windows) presentations ..." -- Nadim on event comments "He [Daniel] also showed us some syntax loopholes in Bash that could leave someone with bad code." -- Ish on MSCC – Let's talk about Scripting   Glad to see a couple of first time attendees, especially students from the university itself. Some details on the presentations MSCC: First time visit at the University of Mauritius - Phase II Engineering Tower, room 2.9 Gimme some love ... bash and other shells Ish gave a great introduction into shell scripting as he spoke about existing shell environments and a little bit about their history. Furthermore, he talked about various built-in commands, the use of coreutils, the ability to daisy-chain multiple commands using pipes, the importance of the standard I/O streams and their file descriptors in advanced scripting techniques. Combined with a couple of sample statements in the Linux terminal on Ubuntu 14.04 machine it was a solid presentation. Have a closer look at his slides - published on his blog on MSCC – Let's talk about Scripting. Oddities of scripting After the brief introduction into bash it was Daniel's turn to highlight a good number of oddities when working with shell scripts. First of all, it should be clear that scripting is not supposed for any kind of implementations in terms of software but simply to automate administrative procedures and to simplify routine jobs on a system. One of the cool oddities that he mentioned is that everything (!) in a shell is represented by strings; there are no other types like integer, float, date-time, etc. that you'd like to use in a full-fledged programming language. Let's have a look at his sample:  more to come... What's the output? As a conclusion, Daniel suggests that shell scripting should be limited but not restricted to automatic repetitive command stacks and batch jobs, startup wrapper for applications in order to set up the execution environment, and other not too sophisticated jobs. But as soon as it might involve a little bit more logic or you might rely on performance it's better to write an application in Ruby, Python, or Perl (among others of course). This is also enables the possibility to test your code properly. MSCC: Ish talking about Bourne Again Shell (bash) and shell scripting to automate regular tasks MSCC: Daniel gives an overview about the pros and cons of shell scripting versus programming MSCC: PowerShell as your scripting solution on Windows operating systems The path of the Enlightened is long ... and tough. Honestly, even though PowerShell was mentioned without any further details on the meetup's agenda, I didn't expect that there would be demand to give a presentation on Microsoft PowerShell after all. I already took this topic out of the announcement but the audience wanted to have some information. Okay, then let's see what I could do - improvised style. While my machine booted and got hooked up to the projector, I started to talk about the beginnings of PowerShell from back in 2006, and its predecessors MS DOS and Command Prompt. A throwback in history... always good for young people. As usual, Microsoft didn't get it at that time. Instead of listening to their client's needs and demands they ignored the feasibility to administrate Windows server farms without any UI tools. PowerShell is actually a result of this, and seeing that shell scripting is a common, reliable and fast way in an administrator's toolbox for decades, Microsoft had to adapt from their Microsoft Management Console (MMC) to a broader approach. It's not like shell scripting was something new; it is in daily use by alternative operating systems like AIX, HP UX, Solaris, and last but not least Linux. Most interestingly, Microsoft is very good at renovating existing architectures, and over the years PowerShell not only replaced their own combination of Command Prompt and Scripting Hosts (VBScript and CScript) but really turned into a challenging competitor on the market. The shell is easy to extend with cmdlets, and open to other Microsoft products like SQL Server, SharePoint, as well as Third-party software applications. Similar to MMC PowerShell also offers the ability to administer other machine remotely - only without a graphical user interface and therefore it's easier to automate and schedule regular tasks. Following is a sample of a PowerShell script file (extension .ps1): $strComputer = "." $colItems = get-wmiobject -class Win32_BIOS -namespace root\CIMV2 -comp $strComputer foreach ($objItem in $colItems) {write-host "BIOS Characteristics: " $objItem.BiosCharacteristicswrite-host "BIOS Version: " $objItem.BIOSVersionwrite-host "Build Number: " $objItem.BuildNumberwrite-host "Caption: " $objItem.Captionwrite-host "Code Set: " $objItem.CodeSetwrite-host "Current Language: " $objItem.CurrentLanguagewrite-host "Description: " $objItem.Descriptionwrite-host "Identification Code: " $objItem.IdentificationCodewrite-host "Installable Languages: " $objItem.InstallableLanguageswrite-host "Installation Date: " $objItem.InstallDatewrite-host "Language Edition: " $objItem.LanguageEditionwrite-host "List Of Languages: " $objItem.ListOfLanguageswrite-host "Manufacturer: " $objItem.Manufacturerwrite-host "Name: " $objItem.Namewrite-host "Other Target Operating System: " $objItem.OtherTargetOSwrite-host "Primary BIOS: " $objItem.PrimaryBIOSwrite-host "Release Date: " $objItem.ReleaseDatewrite-host "Serial Number: " $objItem.SerialNumberwrite-host "SMBIOS BIOS Version: " $objItem.SMBIOSBIOSVersionwrite-host "SMBIOS Major Version: " $objItem.SMBIOSMajorVersionwrite-host "SMBIOS Minor Version: " $objItem.SMBIOSMinorVersionwrite-host "SMBIOS Present: " $objItem.SMBIOSPresentwrite-host "Software Element ID: " $objItem.SoftwareElementIDwrite-host "Software Element State: " $objItem.SoftwareElementStatewrite-host "Status: " $objItem.Statuswrite-host "Target Operating System: " $objItem.TargetOperatingSystemwrite-host "Version: " $objItem.Versionwrite-host} Which gives you information about your BIOS and Windows OS. Then change the computer name to another one on your network (NetBIOS based) and run the script again. There lots of samples and tutorials at the Microsoft Script Center, and I would advise you to pay a visit over there if you are more interested in PowerShell. The Script Center provides the download links, too. Upcoming Events What are the upcoming events here in Mauritius? So far, we have the following ones (incomplete list as usual) in chronological order: Hacking Defence (14. May 2014) WebCup Maurice (7. & 8. June 2014) Developers Conference (TBA ~ July 2014) Linuxfest 2014 (TBA ~ November 2014) Hopefully, there will be more announcements during the next couple of weeks and months. If you know about any other event, like a bootcamp, a code challenge or hackathon here in Mauritius, please drop me a note in the comment section below this article. Thanks! My resume of the day Spontaneous and improvised :) The new location at the University of Mauritius turned out very well, there is plenty of space, and it could be a good choice for future meetings. Especially, having the ability to get more and more students into our IT community sounds like a great opportunity. Later during the day, I got some promising mails from Nadim regarding future sessions at the local branch of the Middlesex University. Well, we will see in the future... But for now this will be on hold until approximately October when students resume their regular studies. Anyway, it was a good experience at the university, and thanks again to the UoM Student's Computer Club that made the necessary arrangements for the MSCC!

  • Backup Meta-Data

    - by BuckWoody
    I'm working on a PowerShell script to show me the trending durations of my backup activities. The first thing I need is the data, so I looked at the Standard Reports in SQL Server Management Studio, and found a report that suited my needs, so I pulled out the script that it runs and modified it to this T-SQL Script. A few words here - you need to be in the MSDB database for this to run, and you can add a WHERE clause to limit to a database, timeframe, type of backup, whatever. For that matter, I won't use all of the data in this query in my PowerShell script, but it gives me lots of avenues to graph: SELECT distinct t1.name AS 'DatabaseName' ,(datediff( ss,  t3.backup_start_date, t3.backup_finish_date)) AS 'DurationInSeconds' ,t3.user_name AS 'UserResponsible' ,t3.name AS backup_name ,t3.description ,t3.backup_start_date ,t3.backup_finish_date ,CASE WHEN t3.type = 'D' THEN 'Database' WHEN t3.type = 'L' THEN 'Log' WHEN t3.type = 'F' THEN 'FileOrFilegroup' WHEN t3.type = 'G' THEN 'DifferentialFile' WHEN t3.type = 'P' THEN 'Partial' WHEN t3.type = 'Q' THEN 'DifferentialPartial' END AS 'BackupType' ,t3.backup_size AS 'BackupSizeKB' ,t6.physical_device_name ,CASE WHEN t6.device_type = 2 THEN 'Disk' WHEN t6.device_type = 102 THEN 'Disk' WHEN t6.device_type = 5 THEN 'Tape' WHEN t6.device_type = 105 THEN 'Tape' END AS 'DeviceType' ,t3.recovery_model  FROM sys.databases t1 INNER JOIN backupset t3 ON (t3.database_name = t1.name )  LEFT OUTER JOIN backupmediaset t5 ON ( t3.media_set_id = t5.media_set_id ) LEFT OUTER JOIN backupmediafamily t6 ON ( t6.media_set_id = t5.media_set_id ) ORDER BY backup_start_date DESC I'll munge this into my Excel PowerShell chart script tomorrow. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only. Keep out of reach of small children. Do not operate heavy machinery while using this script. If you experience blurry vision, indigestion or diarrhea during the operation of this script, see a physician immediately.

  • B2B and B2C alike… but a little different – Oracle Commerce named Leader in Forrester B2B Commerce Wave

    - by Katrina Gosek
    We weren’t surprised to see Oracle Commerce positioned as a Leader in Forrester Research, Inc.’s first Commerce Wave focused on B2B, “The Forrester Wave™: B2B Commerce Suites, Q4 2013,” released earlier this month. We believe that the report validates much of what we’ve heard from our largest customers – the world’s largest distribution, manufacturing and high-tech customers who sell billions of dollars of goods and services to other businesses through their Web channels. More importantly, we feel that the report confirms something very important: B2B and B2C Commerce are alike… but a little different. B2B and B2C Commerce are alike… Clearly, B2C experiences have set expectations for B2B. Every B2B buyer is a consumer at home and brings the same expectations to a website selling electronic components, aftermarket parts, or MRO products. Forrester calls these rich consumer-based capabilities that help B2B customers do their jobs “table stakes”: front-office content, community, and commerce features that meet customer expectations for 24x7x365 ordering, real-time customer service, and expedited shipping — both online and on mobile devices: “Whether they are just beginning to sell online or are in the late stages of launching a next-generation site, B2B eCommerce operations today must: offer a customer experience standard comparable to what leading b2c sites now offer; address the growing influence that mobile devices are having in the workplace; make a qualitative and quantitative business case that drives sustained investment.” Just five years ago, many of our B2B customers’ online business comprised only 5-10% of their total revenue. Today, when we speak to those same brands, we hear about double and triple digit growth in their online channels. Many have seen the percentage of the business they perform in their web channels cross the 30-50% threshold. You can hear first-hand from several Oracle Commerce B2B customers about the success they are seeing, and what they’re trying to accomplish (Carolina Biological, Premier Farnell, DeliXL, Elsevier). It seems that this market momentum is likely the reason Forrester broke out the separate B2B Commerce Wave from the B2C Wave. In fact, B2B is becoming the larger force in commerce, expected to collect twice the online dollars of B2C this year ($559 billion). But a little different… Despite the similarities, there is a key and very important difference between B2C and B2B. Unlike a consumer shopping for shoes, a business shopper buying from a distributor or manufacturer is coming to the Web channel as a part of their job. So in addition to a rich, consumer-like experience this shopper expects, these B2B buyers need quoting tools and complex pricing capabilities, like eProcurement, bulk order entry, and other self-service tools such as account, contract and organization management. Forrester also is emphasizing three additional “back-end” tools and capabilities their clients say they need to drive growth in their B2B online channels: i) product information management (PIM), which provides a single system of record for large part lists and product catalogs; ii) web content management (WCM), needed to manage large volumes of unstructured marketing information, and iii) order management systems (OMS), which manage and orchestrate the complex B2B order life cycle from quote through approval, submission to manufacturing, distribution and delivery. We would like to expand on each of these 3 areas: As Forrester suggests, back-end PIM is definitely needed by B2B Commerce providers. Most B2B companies have made significant investments in enterprise-grade PIMs, given the importance of product data management for aggregation and syndication of content, product attribution, analytics, and handling of complex workflows. While in principle it may sound appealing to have a PIM as part of a commerce offering (especially for SMBs who have to do more with less), our customers have typically found that PIM in a commerce platform is largely redundant with what they already have in-place, and is not fully-featured or robust enough to handle the complexity of the product data sets that B2B distributors and manufacturers usually handle. To meet the PIM needs for commerce, Oracle offers enterprise PIM (Product Hub/Fusion PIM) and a robust enterprise data quality product (EDQP) integrated with the Oracle Commerce solution. These are key differentiators of our offering and these capabilities are becoming even more tightly integrated with Oracle Commerce over time. For Commerce, what customers really need is a robust product catalog and content management system for enabling business users to further enrich and ready catalog and content data to be presented and sold online.  This has been a significant area of investment in the Oracle Commerce platform , which continue to get stronger. We see this combination of capabilities as best meeting the needs of our customers for a commerce platform without adding a largely redundant, less functional PIM in the commerce front-end.  On the topic of web content management, we were pleased to see Forrester cite Oracle’s differentiated digital experience capability in this area and the “unique opportunity in the market to lead the convergence of commerce and content management with the amalgamation of Oracle Commerce with WebCenter Sites (formally FatWire).” Strong content management capabilities are critical for distributors and manufacturers who are frequently serving an engineering audience coming to their websites to conduct product research in search of technical data sheets, drawings, videos and more. The convergence of content, commerce, and experience is critical for B2B brands selling online. Regarding order management, Forrester notes that many businesses use their existing back-end enterprise resource planning (ERP) systems to manage order life cycles.  We hear the same from most of our B2B customers, as they already have an ERP system—if not several of them—and are not interested in yet another one. So what do we take away from the Wave results? Forrester notes that the Oracle Commerce Platform “has always had strong B2B commerce capabilities and Oracle certainly has an exhaustive list of B2B customers using the solution.”  What makes us excited about developing leading B2B solutions are the close relationships with our customers and the clear opportunity in the market – which we'll address in an exciting new release planned for the next 12 months. Oracle has one of the world’s largest B2B customer bases, providing leading solutions across key business-to-business functions – from marketing, sales automation, and service to master data management, and ERP.

  • Garbled UI with vnc, chicken-of-the-vnc, gridengine, qmon

    - by bmargulies
    Ubuntu 11.04 gridengine version 6.2u5-1ubuntu1 I start a desktop with the vncserver command. My ~/.vnc/xstartup ends with 'gnome-session'. I connect to it using chicken-of-the-VNC on my MacOSX Lion system. I run 'qmon'. Much of qmon works, but several critical tasks show hopelessly garbled grid layouts. I have filed a bug report, but I suspect that there is something I am missing that would render (ahem) them legible.
