  • A Letter for Your CEO About Social Marketing’s Future

    - by Mike Stiles
    We’ll leave it to you to decide if or how to sneak this in front of them. Dear Chief: This social marketing thing looks serious. It’s gone beyond having a Facebook page and putting our info and a few promotions on it. It’s seriously disrupting how we’ve always done marketing. And its implications reach well beyond marketing. My concern is that we stay positioned ahead of these changes and are prepared to embrace, adapt and capitalize on these new capabilities as opposed to spending valuable time and money trying to shoehorn social into “the way we’ve always done things.” I’m also concerned about what happens if our competition executes on this before we do. The days of being able to impose our ad messaging on the masses to great effect are numbered. The public now has the tech tools and ability to filter out things that are irrelevant to them. And frankly, spending ad dollars to reach unlikely prospects isn’t the most efficient path for us either. Today, our customers have to genuinely love what we do. That starts with a renewed, customer-centric focus on the quality and usability of our product. If their experience with it is bad, they now have very connected, loud voices that will testify against us. We can’t afford that. Next, their customer service experience, before and after the sale, has to be a pleasant surprise. That requires truly knowing our customers and listening to them. Lip service won’t cut it. We have to get and use as much data on the customer as possible, interact with them wherever they want to interact with us, and commit to impressing them. If we do, they’ll get out there and advertise for us. Since peer-to-peer recommendation is the most effective marketing, that’s money in the bank. Social marketing is about forming relationships, same as how individuals use social. We want them to know us, trust us, and get real value from knowing us. That requires honesty and transparency that before now might have been uncomfortable. I propose that if we clearly make everything we do about our customers’ wants and needs, we’ll have nothing to hide. It will solidify customer loyalty, retention, and thus, revenue. These things can’t happen without certain tools and structural changes in the organization. There are social cloud platforms that integrate social management into all of the necessary areas: CRM, customer service, sales, marketing automation, content marketing, ecommerce, etc. This is will give us a real-time, complete view of the customer so their every interaction with us is attentive, personalized, accurate, relevant, and satisfying. Without it, we’re just a collage of disjointed systems, each gathering data that informs only its own departmental silo. The customer is voluntarily giving us everything we need to know about them to win them over, but we have to start listening and putting the pieces together. There’s still time. Brands are coming to terms with this transition to the socially enabled enterprise, but so far they aren’t moving very fast. Like us, they’re dealing with long-entrenched technologies and processes. CMO’s and CIO’s have to form new partnerships. Content operations have to be initiated and properly staffed and funded. Various departments must be able to utilize interconnected big data. What will separate the winners from the losers? Well chief, that’s why I’m writing you. It’s in your hands. These initiatives won’t get the kind of priority and seriousness that inspire actual deadlines & action unless they come from your desk. You have to be the champion of customer centricity. You have to be our change agent. You have to be our innovator. Otherwise, it’s going to be business as usual, and that puts us in a very vulnerable place. Sincerely, Your Team @mikestilesPhoto: Gary Scott, stock.xchng

  • A temporary disagreement

    - by Tony Davis
    Last month, Phil Factor caused a furore amongst some MVPs with an article that attempted to offer simple advice to developers regarding the use of table variables, versus local and global temporary tables, in their code. Phil makes clear that the table variables do come with some fairly major limitations.no distribution statistics, no parallel query plans for queries that modify table variables.but goes on to suggest that for reasonably small-scale strategic uses, and with a bit of due care and testing, table variables are a "good thing". Not everyone shares his opinion; in fact, I imagine he was rather aghast to learn that there were those felt his article was akin to pulling the pin out of a grenade and tossing it into the database; table variables should be avoided in almost all cases, according to their advice, in favour of temp tables. In other words, a fairly major feature of SQL Server should be more-or-less 'off limits' to developers. The problem with temp tables is that, because they are scoped either in the procedure or the connection, it is easy to allow them to hang around for too long, eating up precious memory and bulking up the shared tempdb database. Unless they are explicitly dropped, global temporary tables, and local temporary tables created within a connection rather than within a stored procedure, will persist until the connection is closed or, with connection pooling, until the connection is reused. It's also quite common with ASP.NET applications to have connection leaks, as Bill Vaughn explains in his chapter in the "SQL Server Deep Dives" book, meaning that the web page exits without closing the connection object, maybe due to an error condition. This will then hang around in the heap for what might be hours before picked up by the garbage collector. Table variables are much safer in this regard, since they are batch-scoped and so are cleaned up automatically once the batch is complete, which also means that they are intuitive to use for the developer because they conform to scoping rules that are closer to those in procedural code. On the surface then, an ideal way to deal with issues related to tempdb memory hogging. So why did Phil qualify his recommendation to use Table Variables? This is another of those cases where, like scalar UDFs and table-valued multi-statement UDFs, developers can sometimes get into trouble with a relatively benign-looking feature, due to way it's been implemented in SQL Server. Once again the biggest problem is how they are handled internally, by the SQL Server query optimizer, which can make very poor choices for JOIN orders and so on, in the absence of statistics, especially when joining to tables with highly-skewed data. The resulting execution plans can be horrible, as will be the resulting performance. If the JOIN is to a large table, that will hurt. Ideally, Microsoft would simply fix this issue so that developers can't get burned in this way; they've been around since SQL Server 2000, so Microsoft has had a bit of time to get it right. As I commented in regard to UDFs, when developers discover issues like with such standard features, the database becomes an alien planet to them, where death lurks around each corner, and they continue to avoid these "killer" features years after the problems have been eventually resolved. In the meantime, what is the right approach? Is it to say "hammers can kill, don't ever use hammers", or is it to try to explain, as Phil's article and follow-up blog post have tried to do, what the feature was intended for, why care must be applied in its use, and so enable developers to make properly-informed decisions, without requiring them to delve deep into the inner workings of SQL Server? Cheers, Tony.

  • Editor's Notebook - Social Aura: Insights from the Oracle Social Media Summit

    - by user462779
    Panelists talk social marketing at the Oracle Social Media Summit On November 14, I traveled to Las Vegas for the first-ever Oracle Social Media Summit. The two day event featured an impressive collection of social media luminaries including: David Kirkpatrick (founder and CEO of Techonomy Media and author of The Facebook Effect), John Yi (Head of Marketing Partnerships, Facebook), Matt Dickman (EVP of Social Business Innovation, Weber Shandwick), and Lyndsay Iorio (Social Media & Communications Manager, NBC Sports Group) among others. It was also a great opportunity to talk shop with some of our new Vitrue and Involver colleagues who have been returning great social media results even before their companies were acquired by Oracle. I was live tweeting the event from @OracleProfit which was great for those who wanted to follow along with the proceedings from the comfort of their office or blackjack table. But I've also found over the years that live tweeting an event is a handy way to take notes: I can sift back through my record of what people said or thoughts I had at the time and organize the Twitter messages into some kind of summary account of the proceedings. I've had nearly a month to reflect on the presentations and conversations at the event and a few key topics have emerged: David Kirkpatrick's comment during the opening presentation really set the stage for the conversations that followed. Especially if you are a marketer or publisher, the idea that you are in a one-way broadcast relationship with your audience is a thing of the past. "Rising above the noise" does not mean reaching for a megaphone, ALL CAPS, or exclamation marks. Hype will not motivate social media denizens to do anything but unfollow and tune you out. But knowing your audience, creating quality content and/or offers for them, treating them with respect, and making an authentic effort to please them: that's what I believe is now necessary. And Kirkpatrick's comment early in the day really made the point. Later in the day, our friends @Vitrue demonstrated this point by elaborating on a comment by Facebook's John Yi. If a social strategy is comprised of nothing more than cutting/pasting the same message into different social media properties, you're missing the opportunity to have an actual conversation. That's not shouting at your audience, but it does feel like an empty gesture. Walter Benjamin, perplexed by auraless Twitter messages Not to get too far afield, but 20th century cultural critic Walter Benjamin has a concept that is useful for understanding the dynamics of the empty social media gesture: Aura. In his work The Work of Art in the Age of Mechanical Reproduction, Benjamin struggled to understand the difference he percieved between the value of a hand-made art object (a painting, wood cutting, sculpture, etc.) and a photograph. For Benjamin, aura is similar to the "soul" of an artwork--the intangible essence that is created when an artist picks up a tool and puts creative energy and effort into a work. I'll defer to Wikipedia: "He argues that the "sphere of authenticity is outside the technical" so that the original artwork is independent of the copy, yet through the act of reproduction something is taken from the original by changing its context. He also introduces the idea of the "aura" of a work and its absence in a reproduction." So make sure you put aura into your social interactions. Don't just mechanically reproduce them. Keeping aura in your interactions requires the intervention of an actual human being. That's why @NoahHorton's comment about content curation struck me as incredibly important. Maybe it's just my own prejudice, being in the content curation business myself. And it's not to totally discount machine-aided content management systems, content recommendation engines, and other tech-driven tools for building an exceptional content experience. It's just that without that human interaction--that editor who reviews the analytics and responds to user feedback--interactions over social media feel a bit empty. It is SOCIAL media, right? (We'll leave the conversation about social machines for another day). At the end of the day, experimentation is key. Just like trying to find that right joke to tell at the beginning of your presentation or that good opening like at a cocktail party, social media messages and interactions can take some trial and error. Don't be afraid to try things, tinker with incomplete ideas, abandon things that don't work, and engage in the conversation. And make sure your heart is in it, otherwise your audience can tell. And finally:

  • BizTalk 2009 - Architecture Decisions

    - by StuartBrierley
    In the first step towards implementing a BizTalk 2009 environment, from development through to live, I put forward a proposal that detailed the options available, as well as the costs and benefits associated with these options, to allow an informed discusion to take place with the business drivers and budget holders of the project.  This ultimately lead to a decision being made to implement an initial BizTalk Server 2009 environment using the Standard Edition of the product. It is my hope that in the long term, as projects require it and allow, we will be looking to implement my ideal recommendation of a multi-server enterprise level environment, but given the differences in cost and the likely initial work load for the environment this was not something that I could fully recommend at this time.  However, it must be noted that this decision was made in full awareness of the limits of the standard edition, and the business drivers of this project were made fully aware of the risks associated with running without the failover capabilities of the enterprise edition. When considering the creation of this new BizTalk Server 2009 environment, I have also recommended the creation of the following pre-production environments:   Usage Environment Development Development of solutions; Unit testing against technical specifications; Initial load testing; Testing of deployment packages;  Visual Studio; BizTalk; SQL; Client PCs/Laptops; Server environment similar to Live implementation; Test Testing of Solutions against business and technical requirements;  BizTalk; SQL; Server environment similar to Live implementation; Pseudo-Live As Live environment to allow testing against Live implementation; Acts as back-up hardware in case of failure of Live environment; BizTalk; SQL; Server environment identical to Live implementation; The creation of these differing environments allows for the separation of the various stages of the development cycle.  The development environment is for use when actively developing a solution, it is a potentially volatile environment whose state at any given time can not be guaranteed.  It allows developers to carry out initial tests in an environment that is similar to the live environment and also provides an area for the testing of deployment packages prior to any release to the test environment. The test environment is intended to be a semi-volatile environment that is similar to the live environment.  It will change periodically through the development of a solution (or solutions) but should be otherwise stable.  It allows for the continued testing of a solution against requirements without the worry that the environment is being actively changed by any ongoing development.  This separation of development and test is crucial in ensuring the quality and control of the tested solution. The pseudo-live environment should be considered to be an almost static environment.  It should mimic the live environment and can act as back up hardware in the case of live failure.  This environment acts as an area to allow for “as live” testing, where the performance and behaviour of the live solutions can be replicated.  There should be relatively few changes to this environment, with software releases limited to “release candidate” level releases prior to going live. Whereas the pseudo-live environment should always mimic the live environment, to save on costs the development and test servers could be implemented on lower specification hardware.  Consideration can also be given to the use of a virtual server environment to further reduce hardware costs in the development and test environments, indeed this virtual approach can also be extended to pseudo-live and live assuming the underlying technology is in place. Although there is no requirement for the development and test server environments to be identical to live, the overriding architecture implemented should be the same as in live and an understanding must be gained of the performance differences to be expected across the different environments.

  • Customizing UPK outputs (Part 1)

    - by [email protected]
    If you are familiar with Oracle's User Productivity Kit, you are aware that UPK is a great product for rapidly developing application training. Did you know that you can also customize the UPK outputs to incorporate your company's logo, colors, and preferred styles? There are several areas that support customization: Logo - Within the developer, you can change the logo for all outputs at one time. Player - The player output uses a style sheet that can be updated to change colors, graphics and other visual branding. Documentation - The print documentation uses a Word-based template that can be modified to match your corporate standards. I'll discuss the first one today, and we'll cover the others in subsequent blogs. Before you begin: If you are working in a multi-user environment, ensure that you have "Modify" permissions for the Styles directory under the Publishing folder. Make a copy of the current styles. This recommendation is for backup purposes. If something goes wrong, you will have a way to recover. Consider creating your own category by creating a new folder under the Styles directory, and then copying the styles into your new folder. When you upgrade to future versions, the system will overwrite the standard styles with any new feature additions and updates that have been made. With your own category, all of your customizations will remain intact. To update the logos in all outputs: From the Tools Menu, choose Customize Logo. Select the category if necessary. Browse to select your logo. You can use any size logo, in any graphic format (*.bmp, *.gif, *.jpeg, *.jpg, *.png, or *.tif). The system will make a copy of your logo and add it to each of the publishing styles. Choose OK, and the update process begins. It may take a few minutes. Helpful hints: The logo you select is used "as is" - no resizing or cropping occurs during this process. The Customize Logo process automates replacing all the logo graphics for online deployment (small_logo.gif and large_logo.gif) and the headers in the documentation outputs. You can manually replace these graphics on an individual style basis if you prefer. The recommended logo size is 230 pixels wide x 44 pixels high. Prior to updating the logos, the system will display the size of the selected logo. If you use a logo that is much larger than the recommended size, the heading area will resize to fit the new logo, but that will impact the space available for your training material. If you are using a multi-user environment, the system will check out the publishing styles to you for the logo updates. After you review the styles, remember to check them in so the rest of your team can access the new changes. I'd be interested in hearing (or seeing) how you brand your UPK. Feel free to share in the comments! --Maria Cozzolino, Manager of Requirements & UI for UPK Product Development PS. For those of you who want to customize the player and documentation NOW, check out the detailed instructions in the Publishing Content chapter of the Content Development Guide.

  • Java 6 Certified with Forms and Reports 10g for EBS 12

    - by John Abraham
    Java 6 is now certified with Oracle Application Server 10g Forms and Reports with Oracle E-Business Suite Release 12 (12.0.6, 12.1.1 and higher). What? Wasn't this already certified? No, but a little background might be useful in understanding why this is a new announcement. We previously certified the use of Java 6 with E-Business Suite Release 12 -- with the sole exception of Oracle Application Server 10g components in the E-Business Suite technology stack. Oracle Application Server 10g originally included Java 1.4.2 as part of its distribution.  E-Business Suite 12 uses, amongst other things, the Oracle Forms and Reports 10g components running on Java 1.4. Java 1.4 in the Oracle Application Server 10g ORACLE_HOME is used exclusively by AS 10g Forms and Reports' for Java functionality.  This version of Java is separate from the Java distribution used by other parts of EBS such as Oracle Containers for Java (OC4J). What's new about this certification? You can now upgrade the older Java 1.4 libraries used by Oracle Forms & Reports 10g to Java 6. This allows you to upgrade the Java releases within the Oracle Application Server 10g ORACLE_HOME to the the same level as the rest of your E-Business Suite technology stack components. Why upgrade? This becomes particularly important for customers as individual vendors' support lifecycle for Java 1.4 reaches End of Life: Oracle's Sun JDK Release 1.4.2's End of Extended Support: February 2013 (Sustaining Support indefinitely after) IBM SDK and JRE 1.4.2's End of Service: September 2013 HP-UX Java 1.4.2's End-of-Life : May 2012 Along with Oracle Forms, Java lies at the heart of the Oracle E-Business Suite.  Small improvements in Java can have significant effects on the performance and stability of the E-Business Suite.  As a notable side-benefit, later versions of Java have improved built-in and third-party tools for JVM performance monitoring and tuning.Our standing recommendation is that you always stay current with the latest available Java update provided by your operating system vendor.  Don't forget to upgrade Forms & Reports to 10.1.2.3 E-Business Suite 12 originally shipped with Oracle Application Server 10g Forms & Reports 10.1.2.0.2.  That version is no longer eligible for Error Correction Support. New Forms and Reports 10g patches are now being released with Forms and Reports 10.1.2.3 as the prerequisite. Forms and Reports 10.1.2.3 was certified for EBS 12 environments in November 2008. If you haven't upgraded your EBS 12 environment to Forms & Reports 10.1.2.3, this is a good opportunity to do so.

  • Using Oracle Linux iSCSI targets with Oracle VM

    - by wim.coekaerts
    A few days ago I had written a blog entry on how to use Oracle Solaris 10 (in my case), ZFS and the iSCSI target feature in Oracle Solaris to create a set of devices exported to my Oracle VM server. Oracle Linux can do this as well and I wanted to make sure I also tried out how to do this on Oracle Linux and here are the results. When you install Oracle Linux 5 update 5 (anything newer than update 3), it comes with an rpm called scsi-target-utils. To begin your quest, should you choose to accept it :) make sure this is installed. rpm -qa |grep scsi-target If it is not installed : up2date scsi-target-utils The target utils come with a tool tgtadm which is similar to iscsitadm on Oracle Solaris. There are 2 components again on the iSCSI server side. (1) create volumes - we will use lvm with lvcreate (2) expose a target using tgtadm. My server has a simple setup. All the disks are part of a single volume group called vgroot. To export a 50Gb volume I just create a new volume : lvcreate -L 50G -nmytest1 vgroot This will show up as a new volume in /dev/mapper as /dev/mapper/vgroot-mytest1. Create as many as you want for your environment. Since I already have my blog entry about the 5 volumes, I am not going to repeat the whole thing. You can just go look at the previous blog entry. Now that we have created the volume, we need to use tgtadm to set it up : make sure the service is running : /etc/init.d/tgtd start or service tgtd start (if you want to keep it running you can do chkconfig tgtd on to start it automatically at boottime) Next you need a targetname to set everything up. My recommendation would be to install iscsi-initiator-utils . This will create an iscsi id and put it in /etc/iscsi/initiatorname.iscsi. For convenience you can do : source /etc/iscsi/initiatorname.iscsi echo $InitiatorName and from here on use $InitiatorName instead of the long complex iqn. create your target : tgtadm --lld iscsi --op new --mode target --tid 1 -T $InitiatorName to show the status : tgtadm --lld iscsi --op show --mode target add the volume previously created : tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/mapper/vgroot-mytest1 re-run status to see it's there : tgtadm --lld iscsi --op show --mode target and just like on Oracle Solaris you now have to export (bind) it : tgtadm --lld iscsi --op bind --mode target --tid 1 -I iqn.1986-03.com.sun:01:2a7526f0ffff If you want to export the lun to every iscsi initiator then replace the iqn with ALL. Of course you have to add the iqn of each iscsi initiator or client you want to connect. In the case of my 2 node Oracle VM server setup, both Oracle VM server's initiator names would have to be added. use status again to see that it has this iqn under ACL tgtadm --lld iscsi --op show --mode target You can drop the --lld iscsi if you want, or alias it. It just makes the command line more obvious as to what you are doing. Oracle VM side : Refer back to the previous blog entry for the detailed setup of my Oracle VM server volumes but the exact same commands will be used there. discover : iscsiadm --mode discovery --type sendtargets --portal login : iscsiadm --mode node --targetname iscsi targetname --portal --login get devices : /etc/init.d/iscsi restart and voila you should be in business. have fun.

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.

  • 45 minutes to talk about C# [closed]

    - by Philip
    I have the opportunity to give a 45 minute talk on C# in the theory of programming languages class I'm taking. The college teaches Java almost exclusively, so that's what all the students are most familiar with. (There's a little C, assembly, Prolog and LISP as well.) I decide what to talk about. It seems to me the best approach is to focus on a few of the big, obvious differences between C# and Java. I don't intend it to be a recommendation to use C# -- there are reasons to use each, mostly because of their ecosystems. So I want to focus on C# as a language. I don't want to go too fast and end up listing a whole bunch of features without showing their usefulness. My current plan is this: Functions as first class objects. This is, in my opinion, one of the biggest differences between C# and Java. The professor briefly mentioned this notion and showed a LISP example, but many of the students have probably never used it. I can show real world examples where it's made my code more readable. Lambda expressions as concise syntax for anonymous functions. Obviously with examples to show how this is useful. The real hit-home examples will be at the end when it's combined with the rest. I don't see an advantage to first showing the old delegate syntax and then replacing it with lambdas -- most of us won't have ever seen delegates anyway so it would just be confusing. The yield keyword and how it's different from returning an array. I have the impression that a lot of C# developers aren't familiar with how to use this. It will likely be very foreign to Java developers. I have some examples from my own work where it was really useful, such as iterating over a tree traversal, or iterating over neighbors in a graph where the neighbors aren't stored in memory. In both cases, doing it in Java would likely mean returning a complete list -- with yield I can stop iterating if I find what I want early on, without using memory for superfluous lists or arrays. Extension methods as a way to write implementation on interfaces. We'll all be familiar with how interfaces don't allow method implementation, and how this leads to code duplication. I'll show a specific example of this and how the extension method can solve the problem. Demonstrate how the above can be combined by implementing some simple Linq methods and using them. Where, Select, First, maybe more depending on how much time is left. Ideas on which ones might 'hit home' the best? There are other things I could talk about such as generics, value types, properties and more. I haven't yet though of good ways to incorporate these. In the case of generics and value types, the advantages might not be obvious or as relevant. Properties are obviously useful, particularly since we're taught strict JavaBeans here, but I don't know if I could integrate it with the "path to Linq" discussion above without it feeling tacked on. So I'm looking for thoughts on how to talk about C#, and what to talk about. Even minor details. I'm sure there are more experienced C# developers than me here who have good insight about what's really important in the language, and what would miss the point.

  • SQL SERVER – Solution – User Not Able to See Any User Created Object in Tables – Security and Permissions Issue

    - by pinaldave
    There is an old quote “A Picture is Worth a Thousand Words”. I believe this quote immensely. Quite often I get phone calls that something is not working if I can help. My reaction is in most of the cases, I need to know more, send me exact error or a screenshot. Until and unless I see the error or reproduce the scenario myself I prefer not to comment. Yesterday I got a similar phone call from an old friend, where he was not sure what is going on. Here is what he said. “When I try to connect to SQL Server, it lets me connect just fine as well let me open and explore the database. I noticed that I do not see any user created instances but when my colleague attempts to connect to the server, he is able to explore the database as well see all the user created tables and other objects. Can you help me fix it? “ My immediate reaction was he was facing security and permission issue. However, to make the same recommendation I suggested that he send me a screenshot of his own SSMS and his friend’s SSMS. After carefully looking at both the screenshots, I was very confident about the issue and we were able to resolve the issue. Let us reproduce the same scenario and many there is some learning for us. Issue: User not able to see user created objects First let us see the image of my friend’s SSMS screen. (Recreated on my machine) Now let us see my friend’s colleague SSMS screen. (Recreated on my machine) You can see that my friend could not see the user tables but his colleague was able to do the same for sure. Now I believed it was a permissions issue. Further to this I asked him to send me another image where I can see the various permissions of the user in the database. My friends screen My friends colleagues screen This indeed proved that my friend did not have access to the AdventureWorks database and because of the same he was not able to access the database. He did have public access which means he will have similar rights as guest access. However, their SQL Server had followed my earlier advise on having limited access for guest access, which means he was not able to see any user created objects. My next question was to validate what kind of access my friend’s colleague had. He replied that the colleague is the admin of the server. I suggested that if my friend was suppose to have admin access to the database, he should request of having admin access to his colleague. My friend promptly asked for the same to his colleague and on following screen he added him as an admin. You can do the same using following T-SQL script as well. USE [AdventureWorks2012] GO ALTER ROLE [db_owner] ADD MEMBER [testguest] GO Once my friend was admin he was able to access all the user objects just like he was expecting. Please note, this complete exercise was done on a development server. One should not play around with security on live or production server. Security is such an issue, which should be left with only senior administrator of the server.

  • Detect Unicode Usage in SQL Column

    One optimization you can make to a SQL table that is overly large is to change from nvarchar (or nchar) to varchar (or char).  Doing so will cut the size used by the data in half, from 2 bytes per character (+ 2 bytes of overhead for varchar) to only 1 byte per character.  However, you will lose the ability to store Unicode characters, such as those used by many non-English alphabets.  If the tables are storing user-input, and your application is or might one day be used internationally, its likely that using Unicode for your characters is a good thing.  However, if instead the data is being generated by your application itself or your development team (such as lookup data), and you can be certain that Unicode character sets are not required, then switching such columns to varchar/char can be an easy improvement to make. Avoid Premature Optimization If you are working with a lookup table that has a small number of rows, and is only ever referenced in the application by its numeric ID column, then you wont see any benefit to using varchar vs. nvarchar.  More generally, for small tables, you wont see any significant benefit.  Thus, if you have a general policy in place to use nvarchar/nchar because it offers more flexibility, do not take this post as a recommendation to go against this policy anywhere you can.  You really only want to act on measurable evidence that suggests that using Unicode is resulting in a problem, and that you wont lose anything by switching to varchar/char. Obviously the main reason to make this change is to reduce the amount of space required by each row.  This in turn affects how many rows SQL Server can page through at a time, and can also impact index size and how much disk I/O is required to respond to queries, etc.  If for example you have a table with 100 million records in it and this table has a column of type nchar(5), this column will use 5 * 2 = 10 bytes per row, and with 100M rows that works out to 10 bytes * 100 million = 1000 MBytes or 1GB.  If it turns out that this column only ever stores ASCII characters, then changing it to char(5) would reduce this to 5*1 = 5 bytes per row, and only 500MB.  Of course, if it turns out that it only ever stores the values true and false then you could go further and replace it with a bit data type which uses only 1 byte per row (100MB  total). Detecting Whether Unicode Is In Use So by now you think that you have a problem and that it might be alleviated by switching some columns from nvarchar/nchar to varchar/char but youre not sure whether youre currently using Unicode in these columns.  By definition, you should only be thinking about this for a column that has a lot of rows in it, since the benefits just arent there for a small table, so you cant just eyeball it and look for any non-ASCII characters.  Instead, you need a query.  Its actually very simple: SELECT DISTINCT(CategoryName)FROM CategoriesWHERE CategoryName <> CONVERT(varchar, CategoryName) Summary Gregg Stark for the tip.

  • Easy Made Easier - Networking

    - by dragonfly
        In my last post, I highlighted the feature of the Appliance Manager Configurator to auto-fill some fields based on previous field values, including host names based on System Name and sequential IP addresses from the first IP address entered. This can make configuration a little faster and a little less subject to data entry errors, particularly if you are doing the configuration on the Oracle Database Appliance itself.     The Oracle Database Appliance Appliance Manager Configurator is available for download here. But why would you download it, if it comes pre-installed on the Oracle Database Appliance? A common reason for customers interested in this new Engineered System is to get a good idea of how easy it is to configure. Beyond that, you can save the resulting configuration as a file, and use it on an Oracle Database Appliance. This allows you to verify the data entered in advance, and in the comfort of your office. In addition, the topic of this post is another strong reason to download and use the Appliance Manager Configurator prior to deploying your Oracle Database Appliance.     The most common source of hiccups in deploying an Oracle Database Appliance, based on my experiences with a variety of customers, involves the network configuration. It is during Step 11, when network validation occurs, that these come to light, which is almost half way through the 24 total steps, and can be frustrating, whether it was a typo, DNS mis-configuration or IP address already in use. This is why I recommend as a best practice taking advantage of the Appliance Manager Configurator prior to deploying an Oracle Database Appliance.     Why? Not only do you get the benefit of being able to double check your entries before you even start on the Oracle Database Appliance, you can also take advantage of the Network Validation step. This is the final step before you review all the data and can save it to a text file. It can be skipped, if you aren't ready or are not connected to the network that the Oracle Database Appliance will be on. My recommendation, though, is to run the Appliance Manager Configurator on your laptop, enter the data or re-load a previously saved file of the data, and then connect to the network that the Oracle Database Appliance will be on. Now run the Network Validation. It will check to make sure that the host names you entered are in DNS and do resolve to the IP addresses you specifiied. It will also ping the IP Addresses you specified, so that you can verify that no other machine is already using them (yes, that has happened at customer sites).     After you have completed the validation, as seen in the screen shot below, you can review the results and move on to saving your settings to a file for use on your Oracle Database Appliance, or if there are errors, you can use the Back button to return to the appropriate screen and correct the data. Once you are satisfied with the Network Validation, just check the Skip/Ignore Network Validation checkbox at the top of the screen, then click Next. Is the Network Validation in the Appliance Manager Configurator required? No, but it can save you time later. I should also note that the Network Validation screen is not part of the Appliance Manager Configurator that currently ships on the Oracle Database Appliance, so this is the easiest way to verify your network configuration.     I hope you are finding this series of posts useful. My next post will cover some aspects of the windowing environment that gets run by the 'startx' command on the Oracle Database Appliance, since this is needed to run the Appliance Manager Configurator via a direct connected monitor, keyboard and mouse, or via the ILOM. If it's been a while since you've used an OpenWindows environment, you'll want to check it out.

  • Government Mandates and Programming Languages

    A recent SEC proposal (which, at over 600 pages, I havent read in any detail) includes the following: We are proposing to require the filing of a computer program (the waterfall computer program, as defined in the proposed rule) of the contractual cash flow provisions of the securities in the form of downloadable source code in Python, a commonly used computer programming language that is open source and interpretive. The computer program would be tagged in XML and required to be filed with the Commission as an exhibit. Under our proposal, the filed source code for the computer program, when downloaded and run (by loading it into an open Python session on the investors computer), would be required to allow the user to programmatically input information from the asset data file that we are proposing to require as described above. We believe that, with the waterfall computer program and the asset data file, investors would be better able to conduct their own evaluations of ABS and may be less likely to be dependent on the opinions of credit rating agencies. With respect to any registration statement on Form SF-1 (Section 239.44) or Form SF-3 (Section 239.45) relating to an offering of an asset-backed security that is required to comply with Item 1113(h) of Regulation AB, the Waterfall Computer Program (as defined in Item 1113(h)(1) of Regulation AB) must be written in the Python programming language and able to be downloaded and run on a local computer properly configured with a Python interpreter. The Waterfall Computer Program should be filed in the manner specified in the EDGAR Filer Manual. I dont see how it can be in investors best interests that the SEC demand a particular programming language be used for software related to investment data.  I have a feeling that investors who use computers at all already have software with which they are familiar, and that the vast majority of them are not running an open source scripting language on their machines to do their financial analysis.  In fact, I would wager that most of them are using tools like Excel, and if they really need to script anything, its being done with VBA in Excel. Now, Im not proposing that the SEC should require that the data be provided in Excel format with VBA scripts included so everyone can easily access the data (despite the fact that this would actually be pretty useful generally).  Rather, I think it is ill-advised for a government agency to make recommendations of this nature, period.  If the goal of the recommendation is to ensure that the way things work is codified in a transparent manner, than I can certainly respect that.  It seems to me that this could be accomplished without dictating the technology to use.  To wit: An Excel document could contain all of the data as well as the formulae necessary, and most likely would not require the end-user to install anything on their machine The SEC could simply create a calculator in the cloud such that any/all investors could use a single canonical web-based (or web service based) tool Millions of Java and .NET developers could write their own implementations You can read more about this issue, including the favorable position on it, on Jayanth Varmas blog.

  • Web Safe Area (optimal resolution) for web app design?

    - by M.A.X
    I'm in the process of designing a new web app and I'm wondering for what 'Web Safe Area' should I optimize the app layout and design. By Web Safe Area I mean the actual area available to display the website in the browser (which is influenced by monitor resolution as well as the space taken up by the browser and OS) I did some investigation and thinking on my own but wanted to share this to see what the general opinion is. Here is what I found: Optimal Display Resolution: w3schools web stats seems to be the most referenced source (however they state that these are results from their site and is biased towards tech savvy users) http://www.w3counter.com/globalstats.php (aggregate data from something like 15,000 different sites that use their tracking services) StatCounter Global Stats Display Resolution (Stats are based on aggregate data collected by StatCounter on a sample exceeding 15 billion pageviews per month collected from across the StatCounter network of more than 3 million websites) NetMarketShare Screen Resolutions (marketshare.hitslink.com) (a web analytics consulting firm, they get data from browsers of site visitors to their on-demand network of live stats customers. The data is compiled from approximately 160 million visitors per month) Display Resolution Summary: There is a bit of variation between the above sources but in general as of Jan 2011 looks like 1024x768 is about 20%, while ~85% have a higher resolution of at least 1280x768 (1280x800 is the most common of these with 15-20% of total web, depending on the source; 1280x1024 and 1366x768 follow behind with 9-14% of the share). My guess would be that the higher resolution values will be even more common if we filter on North America, and even higher if we filter on N.American corporate users (unfortunately I couldn't find any free geographically filtered statistics). Another point to note is that the 1024x768 desktop user population is likely lower than the aforementioned 20%, seeing as the iPad (1024x768 native display) is likely propping up those number (the app I'm designing is flash based, Apple mobile devices don't support flash so iPad support isn't a concern). My recommendation would be to optimize around the 1280x768 constraint (*note: 1280x768 is actually a relatively rare resolution, but I think it's a valid constraint range considering that 1366x768 is relatively common and 1280 is the most common horizontal resolution). Browser + OS Constraints: To further add to the constraints we have to subtract the space taken up by the browser (assuming IE, which is the most space consuming) and the OS (assuming WinXP-Win7): Win7 has the biggest taskbar footprint at a height of 40px (XP's and Vista's is 30px) The default IE8 view uses up 25px at the bottom of the screen with the status bar and a further 120px at the top of the screen with the windows title bar and the browser UI (assuming the default 'favorites' toolbar is present, it would instead be 91px without the favorites toolbar). Assuming no scrollbar, we also loose a total of 4px horizontally for the window outline. This means that we are left with 583px of vertical space and 1276px of horizontal. In other words, a Web Safe Area of 1276 x 583 Is this a correct line of thinking? I'm really surprised that I couldn't find this type of investigation anywhere on the web. Lots of websites talk about designing for 1024x768, but that's only half the equation! There is no mention of browser/OS influences on the actual area you have to display the site/app. Any help on this would be greatly appreciated! Thanks. EDIT Another caveat to my line of thinking above is that different browsers actually take up different amounts of pixels based on the OS they're running on. For example, under WinXP IE8 takes up 142px on top of the screen (instead the aforementioned 120px for Win7) because the file menu shows up by default on XP while in Win7 the file menu is hidden by default. So it looks like on WinXP + IE8 the Web Safe Area would be a mere 572px (768px-142-30-24=572)

  • Why is this mod_rewrite RewriteRule directive not working in the .htaccess file?

    - by morgant
    I've got a site that was hosted on a linux el cheapo hosting service that I'm migrating to my Mac OS X 10.5 Leopard Server server running Apache 2.2.8 & PHP 5.2.5 w/rewrite_module enabled and AllowOverride All, but I'm running into an issue with the following lines in the .htaccess file: RewriteEngine On #RewriteRule ^view/([^/\.]+)/?$ /view.php?item=$1 [L] #RewriteRule ^order/([^/\.]+)/?$ /order.php?item=$1 [L] RewriteRule ^category/([^/\.]+)/?$ /category.php?category=$1 [L] As you can see, I've commented out the RewriteRule directives for /view/ and /order/, so I'm only dealing with /category/. When I attempt to load http://domain.tld/category/2/ it runs category.php (I've added debug code to confirm), but $_SERVER['REQUEST_URI'] comes through as /category/2/ and $_GET['category'] comes through as empty. I'm usually fine with troubleshooting .htaccess files and mod_rewrite directives, but this one's got me stumped for some reason. Update: I followed Josh's suggestion and here's the what's dumped to mod_rewrite.log when I try to access http://domain.tld/category/2/: 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (2) init rewrite engine with requested uri /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) applying pattern '.*' to uri '/category/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) pass through /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (2) init rewrite engine with requested uri /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) applying pattern '.*' to uri '/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) pass through /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/13 -> 13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri '13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/13

  • stunnel crashing

    - by Jay
    I'm trying to use stunnel to secure a legacy application's communications. I can't seem to get it setup and working. Can anyone provide any hints where I'm going wrong? Here's what I'm trying to accomplish: A windows service on a client machine connects to a server on port 7000 using TCP. I'd like to encrypt the communication between client and server. Here's what I've tried: Created a new server that accepts ssl connections on port 7443. Got a certificate for the server and installed it. That seems to work with my test setup. Installed stunnel on my windows machine (version 7.43 from the distribution archive file). Installed libssl32.dll and libeay32.dll in the same directory as stunnel.exe ( from the openssl-0.9.8h-1 binary distribution). Installed it as a service using "stunnel -install" Configured stunnel as follows: debug=7 output=C:\p4\internal\Utility\Proxy\proxy.log service=Proxy taskbar=no [exchange] accept=7000 client=yes connect=proxy.blah.com:7443 I changed my hosts file to trick the old application into connecting through stunnel: server.blah.com 127.0.0.1 # when client looks up server it goes to stunnel proxy.blah.com IP-address-of-server.blah.com # stunnel connects to new server "server.blah.com" now resolves to the machine it's running on (i.e. stunnel). "proxy.blah.com" goes to the real server. stunnel should connect to the server. I start the stunnel service and try to connect.

  • How do I troubleshoot a "Bad Request" in Apache2?

    - by Nick
    I have a PHP application that loads for all URLs except the home page. Visiting "https://my.site.com/" produces a "Bad Request" error message. Any other URL, for example, "https://my.site.com/SomePage/" works just fine. It's only the home page that does not work. All pages use mod_rewrite and get routed through a single dispatch script, Director.php. Accessing Director.php directly also produces the "Bad Request" error. BUT- ALL of the other requests go through Director, and they all work just fine, (excluding the home page), so it can't be an issue with the Director.php script? OR can it? I'm not seeing anything in the Apache2 error log, and I'm not seeing any PHP errors in the PHP Error log. I've tried changing the first line of Director.php to read: echo 'test'; exit(); But I still get a "Bad Request". This is the rewrite log for a request to the home page: 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (2) init rewrite engine with requested uri / 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/$' to uri '/' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$' to uri '/' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (1) pass through / 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (2) init rewrite engine with requested uri /Director.php 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (2) rewrite '/Director.php' - '-[L,NC]' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/$' to uri '-[L,NC]' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$' to uri '-[L,NC]' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (2) local path result: -[L,NC] Apache2 Access Log my.site.com:443 123.123.123.123 - - [18/Feb/2011:05:44:19 +0000] "GET / HTTP/1.1" 400 3223 "-" "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.8) Gecko/20100723 Ubuntu/10.04 (lucid) Firefox/3.6.8" Any ideas?

When I comment it out, the home page loads. The question is, how do I make URLS that actually end in .php go straight through (without breaking the home page)?

  • Why is this mod_rewrite RewriteRule directive not working in the .htaccess file?

    - by morgant
    I've got a site that was hosted on a linux el cheapo hosting service that I'm migrating to my Mac OS X 10.5 Leopard Server server running Apache 2.2.8 & PHP 5.2.5 w/rewrite_module enabled and AllowOverride All, but I'm running into an issue with the following lines in the .htaccess file: RewriteEngine On #RewriteRule ^view/([^/\.]+)/?$ /view.php?item=$1 [L] #RewriteRule ^order/([^/\.]+)/?$ /order.php?item=$1 [L] RewriteRule ^category/([^/\.]+)/?$ /category.php?category=$1 [L] As you can see, I've commented out the RewriteRule directives for /view/ and /order/, so I'm only dealing with /category/. When I attempt to load http://domain.tld/category/2/ it runs category.php (I've added debug code to confirm), but $_SERVER['REQUEST_URI'] comes through as /category/2/ and $_GET['category'] comes through as empty. I'm usually fine with troubleshooting .htaccess files and mod_rewrite directives, but this one's got me stumped for some reason. Update: I followed Josh's suggestion and here's the what's dumped to mod_rewrite.log when I try to access http://domain.tld/category/2/: 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (2) init rewrite engine with requested uri /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) applying pattern '.*' to uri '/category/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) pass through /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (2) init rewrite engine with requested uri /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) applying pattern '.*' to uri '/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) pass through /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/13 -> 13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri '13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/13

  • Extract tar with multiple tars inside?

    - by Andrew Fashion
    Is there a way to untar a file with multiple tars inside? It's suppose to just untar everything inside including untarring the tars inside the tar...

  • Where should I go with hosting my site: VPS, GAE, another option?

    - by Jonathan Hayward
    My website, http://JonathansCorner.com/, began life before 1994 as www.imsa.edu/~jhayward/ and has been through various iterations and improvements to content, HTML, and the like, but remains a literature site that is from a web administrator's perspective fairly simple and primitive: a fair amount of static HTML and supporting files, a little bit of CGI and URI rewriting, .htaccess files providing Expires: headers and the like. An associated site demoes various CGI scripts that fall under the category of "and other creations"; the site as a whole has the purpose of sharing my creative works, and so far a fairly rudimentary use of Apache functionality, supported by Unix tools to, for instance, update RSS feed and the "starting point" link on the home page, has served that purpose fairly well. I looked around here on web hosting, and found the note on web host reccommendations as a good note for "What are some of people's favorite web hosts overall," but I wanted to ask a more focused question of "What are the best web hosts for criteria XYZ:" I am looking at a VPS so I will have root, be able to install stuff and edit Apache's config files etc., running Gentoo or other Linux, BSD, or the like. I would like a system that is secure enough that the host's vulnerabilities are mostly the ones that come along with what I am trying to do: that is, I won't be trying to administer and secure an ancient Linux like some have complained about at 1and1. I would like good uptime/reliability and competent support staff: if the level 1 help desk is going to tell me to go to "My Computer" on a Linux box, I'd like to be able to get past them. Ideally I would like a site hosted within some place that will have low latency for U.S. visitors in particular. I would like a hosting solution that will be with a stable business, one that will probably be around, and one unlikely to vanish without warning. With those things specified, I would be interested in knowing what are the less expensive options. (I expect that some of the things I've specified will knock out all of the cheapest options, but I'm still interested in price.) With all that stated, I'd like to back up a bit and look at whether I am asking the right question. I am concerned that the above is a very good way of asking, "How can I keep my site in line with the wave of the past?" I am wondering if it might be specifically wiser to look to adapt my site to newer technologies instead of trying to keep it on older technologies. For instance, while I would hardly portray my site as a way to show off the full power of Google App Engine, the main site at least should be a straightforward port if I were to do that. And beyond Google App Engine, my knowledge of cloud solutions is basic. If it is a better and more future-proof solution to port my site to another kind of solution, I would be interested in knowing where those future-proof solutions lie. So I would be interested in wisdom. If the question I asked in detail is still a good question to be asking, what would people suggest? Or if I should seriously consider porting my site to a newer basic option, what should I try there? Any thoughts would be appreciated.

  • Amazon EC2 Instance - m1.medium Ubuntu 12.04 - Started to crash three days ago

    - by Joy
    The environment: Amazon EC2 Instance - m1.medium Ubuntu 12.04 Apache 2.2.22 - Running a Drupal Site Using MySQL DB Server RAM info: ~$ free -gt total used free shared buffers cached Mem: 3 1 2 0 0 0 -/+ buffers/cache: 0 2 Swap: 0 0 0 Total: 3 1 2 Hard drive info: Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 4.7G 2.9G 62% / udev 1.9G 8.0K 1.9G 1% /dev tmpfs 751M 180K 750M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1.9G 0 1.9G 0% /run/shm /dev/xvdb 394G 199M 374G 1% /mnt The problem About two days ago the site started failing becaue the MySQL server was shut down by Apache with the following message: kernel: [2963685.664359] [31716] 106 31716 226946 22748 0 0 0 mysqld kernel: [2963685.664730] Out of memory: Kill process 31716 (mysqld) score 23 or sacrifice child kernel: [2963685.664764] Killed process 31716 (mysqld) total-vm:907784kB, anon-rss:90992kB, file-rss:0kB kernel: [2963686.153608] init: mysql main process (31716) killed by KILL signal kernel: [2963686.169294] init: mysql main process ended, respawning That states that the VM was occupying 0.9GB, but my Ram has 2GB free, so 1GB was still left free. I understand that in Linux applications can allocate more memory than physically available. I don't know if this is the problme, it's the first time that it has started to happen. Obviously, the MySQL server tries to restart, but there's no memory for it apparently and it won't restart. Here is its error log: Plugin 'FEDERATED' is disabled. The InnoDB memory heap is disabled Mutexes and rw_locks use GCC atomic builtins Compressed tables use zlib 1.2.3.4 Initializing buffer pool, size = 128.0M InnoDB: mmap(137363456 bytes) failed; errno 12 Completed initialization of buffer pool Fatal error: cannot allocate memory for the buffer pool Plugin 'InnoDB' init function returned error. Plugin 'InnoDB' registration as a STORAGE ENGINE failed. Unknown/unsupported storage engine: InnoDB [ERROR] Aborting [Note] /usr/sbin/mysqld: Shutdown complete I simply restarted the Mysql service. About two hours later it happened again. I restarted it. Then it happened again 9 hours later. So then I thought of the MaxClients parameter of apache.conf, so I went to check it out. It was set at 150. I decided to drop it down to 60. As so: <IfModule mpm_prefork_module> ... MaxClients 60 </IfModule> <IfModule mpm_worker_module> ... MaxClients 60 </IfModule> <IfModule mpm_event_module> ... MaxClients 60 </IfModule> Once I did that, I had the apache2 service restart and it all went smoothly for 3/4 of a day. Since at night the MySQL service shut down once again, but this time it wasn't killed by the Apache2 service. Instead it called the OOM-Killer with the following message: kernel: [3104680.005312] mysqld invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0, oom_score_adj=0 kernel: [3104680.005351] [<ffffffff81119795>] oom_kill_process+0x85/0xb0 kernel: [3104680.548860] init: mysql main process (30821) killed by KILL signal Now I'm out of ideas. Some articles state that the ideal thing to do is change the kernel behaviour with the following (include it to the file /etc/sysctl.conf ) vm.overcommit_memory = 2 vm.overcommit_ratio = 80 So no overcommits will take place. I'm wondering if this is the way to go? Keep in mind I'm no server administrator, I have basic knowldege. Thanks a bunch in advance.

  • stunnel crashing

    - by Jay
    I'm trying to use stunnel to secure a legacy application's communications. I can't seem to get it setup and working. Can anyone provide any hints where I'm going wrong? Here's what I'm trying to accomplish: A windows service on a client machine connects to a server on port 7000 using TCP. I'd like to encrypt the communication between client and server. Here's what I've tried: Created a new server that accepts ssl connections on port 7443. Got a certificate for the server and installed it. That seems to work with my test setup. Installed stunnel on my windows machine (version 7.43 from the distribution archive file). Installed libssl32.dll and libeay32.dll in the same directory as stunnel.exe ( from the openssl-0.9.8h-1 binary distribution). Installed it as a service using "stunnel -install" Configured stunnel as follows: debug=7 output=C:\p4\internal\Utility\Proxy\proxy.log service=Proxy taskbar=no [exchange] accept=7000 client=yes connect=proxy.blah.com:7443 I changed my hosts file to trick the old application into connecting through stunnel: server.blah.com 127.0.0.1 # when client looks up server it goes to stunnel proxy.blah.com IP-address-of-server.blah.com # stunnel connects to new server "server.blah.com" now resolves to the machine it's running on (i.e. stunnel). "proxy.blah.com" goes to the real server. stunnel should connect to the server. I start the stunnel service and try to connect. It looks like it's working but the stunnel service just shuts down with no message. 2010.04.19 13:16:21 LOG5[4924:3716]: stunnel 4.33 on x86-pc-mingw32-gnu with OpenSSL 0.9.8h 28 May 2008 2010.04.19 13:16:21 LOG5[4924:3716]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2010.04.19 13:16:49 LOG5[4924:3748]: Service exchange accepted connection from 127.0.0.1:4134 2010.04.19 13:16:49 LOG6[4924:3748]: connect_blocking: connecting x.80.60.32:7443 2010.04.19 13:16:49 LOG5[4924:3748]: connect_blocking: connected x.80.60.32:7443 2010.04.19 13:16:49 LOG5[4924:3748]: Service exchange connected remote server from x.253.120.19:4135 2010.04.19 13:20:24 LOG5[3668:3856]: Reading configuration from file stunnel.conf 2010.04.19 13:20:24 LOG7[3668:3856]: Snagged 64 random bytes from C:/.rnd 2010.04.19 13:20:24 LOG7[3668:3856]: Wrote 1024 new random bytes to C:/.rnd 2010.04.19 13:20:24 LOG7[3668:3856]: RAND_status claims sufficient entropy for the PRNG 2010.04.19 13:20:24 LOG7[3668:3856]: PRNG seeded successfully 2010.04.19 13:20:24 LOG7[3668:3856]: SSL context initialized for service exchange 2010.04.19 13:20:24 LOG5[3668:3856]: Configuration successful 2010.04.19 13:20:24 LOG5[3668:3856]: No limit detected for the number of clients 2010.04.19 13:20:24 LOG7[3668:3856]: FD=312 in non-blocking mode 2010.04.19 13:20:24 LOG7[3668:3856]: Option SO_REUSEADDR set on accept socket 2010.04.19 13:20:24 LOG7[3668:3856]: Service exchange bound to 0.0.0.0:7000 2010.04.19 13:20:24 LOG7[3668:3856]: Service exchange opened FD=312 2010.04.19 13:20:24 LOG5[3668:3856]: stunnel 4.33 on x86-pc-mingw32-gnu with OpenSSL 0.9.8h 28 May 2008 2010.04.19 13:20:24 LOG5[3668:3856]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2010.04.19 13:21:02 LOG7[3668:4556]: Service exchange accepted FD=372 from 127.0.0.1:4156 2010.04.19 13:21:02 LOG7[3668:4556]: Creating a new thread 2010.04.19 13:21:02 LOG7[3668:4556]: New thread created 2010.04.19 13:21:02 LOG7[3668:3756]: Service exchange started 2010.04.19 13:21:02 LOG7[3668:3756]: FD=372 in non-blocking mode 2010.04.19 13:21:02 LOG5[3668:3756]: Service exchange accepted connection from 127.0.0.1:4156 2010.04.19 13:21:02 LOG7[3668:3756]: FD=396 in non-blocking mode 2010.04.19 13:21:02 LOG6[3668:3756]: connect_blocking: connecting x.80.60.32:7443 2010.04.19 13:21:02 LOG7[3668:3756]: connect_blocking: s_poll_wait x.80.60.32:7443: waiting 10 seconds 2010.04.19 13:21:02 LOG5[3668:3756]: connect_blocking: connected x.80.60.32:7443 2010.04.19 13:21:02 LOG5[3668:3756]: Service exchange connected remote server from x.253.120.19:4157 2010.04.19 13:21:02 LOG7[3668:3756]: Remote FD=396 initialized 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): before/connect initialization 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write client hello A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server hello A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server certificate A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server done A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write client key exchange A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write change cipher spec A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write finished A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 flush data 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read finished A The client thinks the connection is closed: No connection could be made because the target machine actively refused it 127.0.0.1:7000 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Connect(EndPoint remoteEP) at Service.ConnUtility.Connect() Any suggestions?

  • JBoss https on port other than 8080 not working

    - by MilindaD
    We have a server with two JBoss instances where one runs on 8080, the other on 8081. We need to have HTTPS enabled for the 8081 server, firstly we tried enabling https on the 8080 port instance by generating the keystore and editing the server.xml and it successfully worked. However when we tried the same thing for 8081 it did not, note that we removed https for the 8080 server first before enabling it for 8081. This is what was used for both server.xml for 8080 and 8081. The only difference was that the port was changed from 8080 to 8081 when trying to enable https for 8081 port instance. What am I doing wrong and what needs to be changed? NOTE : When I meant enabled for 8080 I meant when you visit https:// URL:8484 you will actually be visiting the 8080 port instance. However when ssl is enabled for 8081 and I visit https:// URL:8484 I get that the web page is unavailable.

  • need assistance with my.cnf - 1500% CPU usage

    - by Alan Long
    I'm running into a few issues with our new database server. It is a HP G8 with 2 INTEL XEON E5-2650 processors and 32GB of ram. This server is dedicated as a MySQL server (5.1.69) for our intranet portal. I have been having issues with this server staying alive - I notice high CPU usage during certain times of day (8% ~ 1500%+) and see very low memory usage (7 ~ 15%) based on using the 'top' command. When the CPU usage passes 1000%, that is when the app usually dies. I'm trying to see what I'm doing wrong with the config file, hopefully one of the experts can chime in and let me know what they think. See below for my.cnf file: [mysqld] default-storage-engine=InnoDB datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock #user=mysql large-pages # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 max_connections=275 tmp_table_size=1G key_buffer_size=384M key_buffer=384M thread_cache_size=1024 long_query_time=5 low_priority_updates=1 max_heap_table_size=1G myisam_sort_buffer_size=8M concurrent_insert=2 table_cache=1024 sort_buffer_size=8M read_buffer_size=5M read_rnd_buffer_size=6M join_buffer_size=16M table_definition_cache=6k open_files_limit=8k slow_query_log #skip-name-resolve # Innodb Settings innodb_buffer_pool_size=18G innodb_thread_concurrency=0 innodb_log_file_size=1G innodb_log_buffer_size=16M innodb_flush_log_at_trx_commit=2 innodb_lock_wait_timeout=50 innodb_file_per_table #innodb_buffer_pool_instances=4 #eliminating double buffering innodb_flush_method = O_DIRECT flush_time=86400 innodb_additional_mem_pool_size=40M #innodb_io_capacity = 5000 #innodb_read_io_threads = 64 #innodb_write_io_threads = 64 # increase until threads_created doesnt grow anymore thread_cache=1024 query_cache_type=1 query_cache_limit=4M query_cache_size=256M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 0 wait_timeout = 1800 connect_timeout = 10 interactive_timeout = 60 [mysqldump] max_allowed_packet=32M [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid log-slow-queries=/var/log/mysql/slow-queries.log long_query_time = 1 log-queries-not-using-indexes we connect to one database with 75 tables, the largest table has 1,150,000 entries and the second largest has 128,036 entries.

  • OCR anything with OneNote 2007 and 2010

    - by Matthew Guay
    Quality OCR software can often be very expensive, but you may have one already installed on your computer that you didn’t know about.  Here’s how you can use OneNote to OCR anything on your computer. OneNote is one of the overlooked gems in recent versions of Microsoft Office.  OneNote makes it simple to take notes and keep track of everything with integrated search, and offers more features than its popular competitor Evernote.  One way it is better is its high quality optical character recognition (OCR) engine.  One of Evernote’s most popular features is that you can search for anything, including text in an image, and you can easily find it.  OneNote takes this further, and instantly OCRs any text in images you add.  Then, you can use this text easily and copy it from the image.  Let’s see how this works and how you can use OneNote as the ultimate OCR. Please Note: This feature is available in OneNote 2007 and 2010.  OneNote 2007 is included with Office 2007 Home and Student, Enterprise, and Ultimate, while OneNote 2010 is included with all edition of Office 2010 except for Starter edition. OCR anything First, let’s add something to OCR into OneNote.  There are many different ways you can add items to OCR into OneNote.  Open a blank page or one you want to insert something into, and then follow these steps to add what you want into OneNote. Picture Simply drag-and-drop a picture with text into a notebook… You can insert a picture directly from OneNote as well.  In OneNote 2010, select the Insert tab, and then choose Picture. In OneNote 2007, select the Insert menu, select Picture, and then choose From File.   Screen Clipping There are many times we’d like to copy text from something we see onscreen, but there is no direct way to copy text from that thing.  For instance, you cannot copy text from the title-bar of a window, or from a flash-based online presentation.  For these cases, the Screen Clipping option is very useful.  To add a clip of anything onscreen in OneNote 2010, select the Insert tab in the ribbon and click Screen Clipping. In OneNote 2007, either click the Clip button on the toolbar or select the Insert menu and choose Screen Clipping.   Alternately, you can take a screen clipping by pressing the windows key + S. When you click Screen Clipping, OneNote will minimize, your desktop will fade lighter, and your mouse pointer will change to a plus sign.  Now, click and drag over anything you want to add to OneNote.  Here we’re selecting the title of this article. The section you selected will now show up in your OneNote notebook, complete with the date and time the clip was made. Insert a file You’re not limited to pictures; OneNote can even OCR anything in most files on your computer.  You can add files directly in OneNote 2010 by selecting File Printout in the Insert tab. In OneNote 2007, select the Insert menu and choose Files as Printout. Choose the file you want to add to OneNote in the dialog. Select Insert, and OneNote will pause momentarily as it processes the file. Now your file will show up in OneNote as a printout with a link to the original file above it. You can also send any file directly to OneNote via the OneNote virtual printer.  If you have a file open, such as a PDF, that you’d like to OCR, simply open the print dialog in that program and select the “Send to OneNote” printer. Or, if you have a scanner, you can scan documents directly into OneNote by clicking Scanner Printout in the Insert tab in OneNote 2010. In OneNote 2003, to add a scanned document select the Insert menu, select Picture, and then choose From Scanner or Camera. OCR the image, file, or screenshot you put in OneNote Now that you’ve got your stuff into OneNote, let’s put it to work.  OneNote automatically did an OCR scan on anything you inserted into OneNote.  You can check to make sure by right-clicking on any picture, screenshot, or file you inserted.  Select “Make Text in Image Searchable” and then make sure the correct language is selected. Now, you can copy text from the Picture.  Simply right-click on the picture, and select “Copy Text from Picture”. And here’s the text that OneNote found in this picture: OCR anything with OneNote 2007 and 2010 - Windows Live Writer Not bad, huh?  Now you can paste the text from the picture into a document or anywhere you need to use the text. If you are instead copying text from a printout, it may give you the option to copy text from this page or all pages of the printout.   This works the exact same in OneNote 2007. In OneNote 2010, you can also edit the text OneNote has saved in the image from the OCR.  This way, if OneNote read something incorrectly you can change it so you can still find it when you use search in OneNote.  Additionally, you can copy only a specific portion of the text from the edit box, so it can be useful just for general copying as well.  To do this, right-click on the item and select “Edit Alt Text”. Here is the window to edit alternate text.  If you want to copy only a portion of the text, simply select it and press Ctrl+C to copy that portion. Searching OneNote’s OCR engine is very useful for finding specific pictures you have saved in OneNote.  Simply enter your search query in the search box on top right, and OneNote will automatically find all instances of that term in all of your notebooks.  Notice how it highlights the search term even in the image! This works the same in OneNote 2007.  Notice how it highlighted “How-to” in a shot of the header image in our favorite website. In Windows Vista and 7, you can even search for things OneNote OCRed from the Start Menu search.  Here the start menu search found the words “Windows Live Writer” in our OCR Test notebook in OneNote where we inserted the screen clip above. Conclusion OneNote is a very useful OCR tool, and can help you capture text from just about anything.  Plus, since you can easily search everything you have stored in OneNote, you can quickly find anything you insert anytime.  OneNote is one of the least-used Office tools, but we have found it very useful and hope you do too.
