  • Mysql out of disk space

    - by Paddy
    I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

  • Deploying an ADF Secure Application using WLS Console

    - by juan.ruiz
    Last week I worked on a requirement from a customer that wanted to understand how to deploy to WLS an application with ADF Security without using JDeveloper. The main question was, what steps where needed in order to set up Enterprise Roles, Security Policies and Application Credentials. In this entry I will explain the steps taken using JDeveloper 11.1.1.2. 0 Requirements: Instead of building a sample application from scratch, we can use Andrejus 's sample application that contains all the security pieces that we need. Open and migrate the project. Also make sure you adjust the database settings accordingly. Creating the EAR file Review the Security settings of the application by going into the Application -> Secure menu and see that there are two enterprise roles as well as the ADF Policies enforcing security on the main page. Make sure the Application Module uses the Data Source instead of JDBC URL for its connection type, also take note of the data source name - in my case I have: java:comp/env/jdbc/HrDS To facilitate the access to this application once we deploy it. Go to your ViewController project properties select the Java EE Application category and give it a meaningful name to the context root as well to the Application Name Go to the ADFSecurityWL Application properties -> Deployment  and create a new EAR deployment profile. Uncheck the Auto generate and Synchronize weblogic-jdbc.xml Descriptors During Deployment Deploy the application as an EAR file. Deploying the Application to WLS using the WLS Console On the WLS console create a JNDI data source. This is the part that I found more tricky of the hole exercise given that the name should match the AM's data source name, however the naming convention that worked for me was jdbc.HrDS Now, deploy the application manually by selecting deployments ->Install look for the EAR and follow the default steps. If this is the firs time you deploy the application, once the deployment finishes you will be asked to Activate Changes on the domain, these changes contain all the security policies and application roles insertion into the WLS instance. Creating Roles and User Groups for the Application To finish the after-deployment set up, we need to create the groups that are the equivalent of the Enterprise Roles of ADF Security. For our sample we have two Enterprise Roles employeesApplication and managersApplication. After that, we create the application users and assign them into their respective groups. Now we can run the application and test the security constraints

  • eBay Leads Mobile Commerce

    - by David Dorf
    For the first time, more smartphones where shipped than PCs. This important milestone helps reinforce that retailers need a strong mobile commerce strategy. IDC reported that for the 4th quarter of 2010, manufacturers shipped 100.9 million devices versus 92.1 million PCs shipped. One early adopter for the retail industry is eBay, the popular online auction and shopping site. In July 2008 they released their first mobile app and have increased investments ever since. In 2002 they bought PayPal for use with its online channel, but its becoming a force in the mobile world as well. In June 2010 they acquired RedLaser, the popular barcode scanning mobile app. Both pieces of technology enhance the mobile experience, and are available to other retailers as well. More recently, in December 2010 they acquired Critical Path Software, the developer of their eBay, StubHub, and Shopping.com mobile applications. Taking their mobile development in-house was a clear signal that mobile commerce is important to their strategy. Pop on over the eBay Inc's mobile commerce stats page to see just how well they are doing. You can use the animated map to see where people are using the app on any given day, and you can compare sales of the different categories. eBay's hottest category is Cars & Trucks, garnering 16.5% of the total $2B (yes, billion) in mobile sales in 2010. To understand why that category is so large, let's look at the top 10 most expensive cars sold on eBay mobile in 2010: $240,001 Mercedes-Benz: SLR McLaren $209,888 Lamborghini: Gallardo $208,500 Ferrari: 430 $199,900 Lamborghini: Gallardo $189,000 Lamborghini: Murcielago $185,000 Ferrari: 430 $175,000 Porsche: 911 $170,000 Ferrari: 550 $160,000 Bentley: Continental, GT $159,900 Lamborghini: Gallardo eBay claims they sell 3-4 Ferraris on their mobile app each month. Yes, mobile commerce is not limited to small items. While I would wait to get home and fire up the PC, the current generation that has grown up with mobile phones has no issue satisfying their impulses. Dave Sikora of Digby told me he's seen people buy furniture sets, mattresses, and diamonds via their mobile phones. I guess mobile commerce is rapidly becoming the norm.

  • QotD: Matt Stephens on OpenJDK in 2012 at the Register

    - by $utils.escapeXML($entry.author)
    While Java SE churns and gets pushed back, the new initiatives do at least show OpenJDK is reinvigorating the Java space. The project has picked up speed just a little too late for the fifth anniversary of the open-sourcing of Java, but if these promised developments really do come together then that means next year should see a series of “one last things” missing from 2011.Matt Stephens in an article in the Register.

  • After restoring a SQL Server database from another server - get login fails

    - by Renso
    Issue: After you have restored a sql server database from another server, lets say from production to a Q/A environment, you get the "Login Fails" message for your service account. Reason: User logon information is stored in the syslogins table in the master database. By changing servers, or by altering this information by rebuilding or restoring an old version of the master database, the information may be different from when the user database dump was created. If logons do not exist for the users, they will receive an error indicating "Login failed" while attempting to log on to the server. If the user logons do exist, but the SUID values (for 6.x) or SID values (for 7.0) in master..syslogins and the sysusers table in the user database differ, the users may have different permissions than expected in the user database. Solution: Links a user entry in the sys.database_principals system catalog view in the current database to a SQL Server login of the same name. If a login with the same name does not exist, one will be created. Examine the result from the Auto_Fix statement to confirm that the correct link is in fact made. Avoid using Auto_Fix in security-sensitive situations. When you use Auto_Fix, you must specify user and password if the login does not already exist, otherwise you must specify user but password will be ignored. login must be NULL. user must be a valid user in the current database. The login cannot have another user mapped to it. execute the following stored procedure, in this example the login user name is "MyUser" exec sp_change_users_login 'Auto_Fix', 'MyUser'   NOTE: sp_change_users_login cannot be used with a SQL Server login created from a Windows principal or with a user created by using CREATE USER WITHOUT LOGIN.

  • What's the value of a Facebook fan?

    - by David Dorf
    In his blog posting titled "Why Each Facebook Fan Is Worth $2,000 to J. Crew," Joe Skorupa lays out a simplistic calculation for assigning a value to social media efforts within Facebook. While I don't believe the metric, at least its a metric that can be applied consistently. Trying to explain the ROI to management to start a program, then benchmarking to show progress isn't straightforward at all. Social media isn't really mature enough to have hard-and-fast rules around valuation (yet). When I'm asked by retailers how to measure social media efforts, I usually fess-up and say I can't show an ROI but the investment is so low you might was well take a risk. Intuitively, it just seems like a good way to interact with consumers, and since your competition is doing it, you better do it as well. Vitrue, a social media management company, has calculated a fan as being worth $3.60 per year based on impressions generated in Facebook's news feed. That means a fan base of 1 million translates into at least $3.6 million in equivalent media over a year. Don't believe that number either? Fine, Vitrue now has a tool that let's you adjust the earned media value of a fan. Jump over to http://evaluator.vitrue.com/ and enter your brand's Facebook URL to get an assessment of the current value and potential value. For fun, I compared Abercrombie & Fitch (1,077,480 fans), Gap (567,772 fans), and Wet Seal (294,479 fans). The image below shows the results assuming the default $5 earned media value for a fan. The calculation is more complicated than just counting fans. It also accounts for postings and comments. Its possible for a brand with fewer fans to have a higher value based on frequency and relevancy of posts. The tool gathers data via the Social Graph API for the past 30 days of activity. I'm not sure this tool assigns the correct value either, but hey, its a great start.

  • The Social Business Thought Leaders - John Hagel

    - by kellsey.ruppel
    While many European economies are on the brink of a recession between increasing taxation and mounting loss of jobs and bankruptcy filing rates, there's an understandable risk of losing sight of the deeper forces at play. Yet instead of surrendering to uncertainty and trying to survive in the short term, many organizations are feeling the urge to be better prepared to thrive in these complex times by developing a more articulated long term understanding of both the opportunities / challenges ahead. For example: What long-term economic, technological and societal changes are rolling out? Which foundational dynamics will affect our companies' performance, productivity, competition, and innovative potential in the upcoming decades? How will digital infrastructure change our business landscape? What kind of capabilities will be key to compete in a market shaped by growing turbulence, unpredictability and volatility? Breaking out from a strictly cyclical thinking, studies such as the Shift Index by John Hagel, Co-Chairman of the Center for the Edge at Deloitte & Touche (See Measuring the forces of long-term change - The 2009 Shift Index), depict a worrying performance challenge that affected every industry in the entire US economy over the last 45 years. Amidst a more than doubled competitive intensity of the market, and even with an improved labor productivity, the actual performance of US firms has consistently fallen to 25% of what it was in 1965. Most of this reported value is shifting from institutions and organizations to individuals, whether they are customers or young creative talent. To thrive in the digital economy and reverse declining performance trends, companies will have to fundamentally rethink their management approach by moving from knowledge stocks to knowledge flows, from scalable efficiency to scalable learning, from push organizations to pull organizations. Based on the outcomes of the Shift Index and on the book The Power of Pull, the first episode of the Social Business Thought-Leaders features John Hagel to provide strategic insights on how companies will succeed in the 21st century.

  • When Less is More

    - by aditya.agarkar
    How do you reconcile the fact that while the overall warehouse volume is down you still need more workers in the warehouse to ship all the orders? A WMS customer recently pointed out this seemingly perplexing fact in a customer conference. So what is going on? Didn't we tell you before that for a warehouse the customer is really the "king"? In this case customers are merely responding to a low overall low demand and uncertainty. They do not want to hold down inventory and one of the ways to do that is by decreasing the order size and ordering more frequently. Overall impact to the warehouse? Two words: "More work!!" This is not all. Smaller order sizes also mean challenges from a transportation perspective including a rise in costlier parcel or LTL shipments instead of cheaper TL shipments. Here is a hypothetical scenario where a customer reduces the order size by 10% and increases the order frequency by 10%. As you can see in the following table, the overall volume declines by 1% but the warehouse has to ship roughly 10% more lines. Order Frequency (Line Count)Order Size (Units)Total VolumeChange (%)10010010,000 -110909,900-1% If you want to see how "Less is More" in graphical terms, this is how it appears: Even though the volume is down, there is going to be more work in the warehouse in terms of number of lines shipped. The operators need to pick more discrete orders, pack them into more shipping containers and ship more deliveries. What do you do differently if you are facing this situation?In this case here are some obvious steps to take:Uno: Change your pick methods. If you are used to doing order picks, it needs to go out the door. You need to evaluate batch picking and grouping techniques. Go for cluster picking, go for zone picking, pick and pass...anything that improves your picker productivity. More than anything, cluster picking works like a charm and above all, its simple and very effective. Dos: Are you minimize "touch" points in your pick process? Consider doing one step pick, pack and confirm i.e. pick and pack stuff directly into shipping cartons. Done correctly the container will not require any more "touch" points all the way to the trailer loading. Use cartonization!Tres: Are the being picked from an optimized pick face? Are the items slotted correctly? This needs to be looked into. Consider automated "pull" or "push" replenishment into your pick face and also make sure that high demand items are occupying the golden zones.  Cuatro: Are you tracking labor productivity? If not there needs to be a concerted push for having labor standards in place. Hope you found these ideas useful.

  • Sorting: TransientVO Vs Query/EO based VO

    - by Vijay Mohan
    In ADF, you can do a sorting on VO rows by invoking setSortBy("VOAttrName") API, but the tricky part is that, this API actually appends a clause to VO query at runtime and the actual sorting is performed after doing VO.executeQuery(), this goes fine for Query/EO based VO. But, how about the transient VO, wherein the rows are populated programmatically..?There is a way to it..:)you can actually specify the query mode on your transient VO, so that the sorting happens on already populated VO rows.Here are the steps to go about it..//Populate your transient VO rows.//VO.setSortBy("YourVOAttrName");//VO.setQueryMode(ViewObject.QUERY_MODE_SCAN_VIEW_ROWS);//VO.executeQuery();So, here the executeQuery() is actually the trigger which calls for VO rows sorting.QUERY_MODE_SCAN_VIEW_ROWS flag makes sure that the sorting is performed on the already populated VO cache.

  • La búsqueda de la eficiencia como Santo Grial de las TIC sanitarias

    - by Eloy M. Rodríguez
    Las XVIII Jornadas de Informática Sanitaria en Andalucía se han cerrado el pasado viernes con 11.500 horas de inteligencia colectiva. Aunque el cálculo supongo que resulta de multiplicar las horas de sesiones y talleres por el número de inscritos, lo que no sería del todo real ya que la asistencia media calculo que andaría por las noventa personas, supongo que refleja el global si incluimos el montante de interacciones informales que el formato y lugar de celebración favorecen. Mi resumen subjetivo es que todos somos conscientes de que debemos conseguir más eficiencia en y gracias a las TIC y que para ello hemos señalado algunas pautas, que los asistentes, en sus diferentes roles debiéramos aplicar y ayudar a difundir. En esa línea creo que destaca la necesidad de tener muy claro de dónde se parte y qué se quiere conseguir, para lo que es imprescindible medir y que las medidas ayuden a retroalimentar al sistema en orden de conseguir sus objetivos. Y en este sentido, a nivel anecdótico, quisiera dejar una paradoja que se presentó sobre la eficiencia: partiendo de que el coste/día de hospitalización es mayor al principio que los últimos días de la estancia, si se consigue ser más eficiente y reducir la estancia media, se liberarán últimos días de estancia que se utilizarán para nuevos ingresos, lo que hará que el número de primeros días de estancia aumente el coste económico total. En este caso mejoraríamos el servicio a los ciudadanos pero aumentaríamos el coste, salvo que se tomasen acciones para redimensionar la oferta hospitalaria bajando el coste y sin mejorer la calidad. También fue tema destacado la posibilidad/necesidad de aprovechar las capacidades de las TIC para realizar cambios estructurales y hacer que la medicina pase de ser reactiva a proactiva mediante alarmas que facilitasen que se actuase antes de ocurra el problema grave. Otro tema que se trató fue la necesidad real de corresponsabilizar de verdad al ciudadano, gracias a las enormes posibilidades a bajo coste que ofrecen las TIC, asumiendo un proceso hacia la salud colaborativa que tiene muchos retos por delante pero también muchas más oportunidades. Y la carpeta del ciudadano, emergente en varios proyectos e ideas, es un paso en ese aspecto. Un tema que levantó pasiones fue cuando la Directora Gerente del Sergas se quejó de que los proyectos TIC eran lentísimos. Desgraciadamente su agenda no le permitió quedarse al debate que fue bastante intenso en el que salieron temas como el larguísimo proceso administrativo, las especificaciones cambiantes, los diseños a medida, etc como factores más allá de la eficiencia especifica de los profesionales TIC involucrados en los proyectos. Y por último quiero citar un tema muy interesante en línea con lo hablado en las jornadas sobre la necesidad de medir: el Índice SEIS. La idea es definir una serie de criterios agrupados en grandes líneas y con un desglose fino que monitorice la aportación de las TIC en la mejora de la salud y la sanidad. Nos presentaron unas versiones previas con debate aún abierto entre dos grandes enfoques, partiendo desde los grandes objetivos hasta los procesos o partiendo desde los procesos hasta los objetivos. La discusión no es sólo académica, ya que influye en los parámetros a establecer. La buena noticia es que está bastante avanzado el trabajo y que pronto los servicios de salud podrán tener una herramienta de comparación basada en la realidad nacional. Para los interesados, varios asistentes hemos ido tuiteando las jornadas, por lo que el que quiera conocer un poco más detalles puede ir a Twitter y buscar la etiqueta #jisa18 y empezando del más antiguo al más moderno se puede hacer un seguimiento con puntos de vista subjetivos sobre lo allí ocurrido. No puedo dejar de hacer un par de autocríticas, ya que soy miembro de la SEIS. La primera es sobre el portal de la SEIS que no ha tenido la interactividad que unas jornadas como estas necesitaban. Pronto empezará a tener documentos y análisis de lo allí ocurrido y luego vendrán las crónicas y análisis más cocinados en la revista I+S. Pero en la segunda década del siglo XXI se necesita bastante más. La otra es sobre la no deseada poca presencia de usuarios de las TIC sanitarias en los roles de profesionales sanitarios y ciudadanos usuarios de los sistemas de información sanitarios. Tenemos que ser proactivos para que acudan en número significativo, ya que si no estamos en riesgo de ser unos TIC-sanitarios absolutistas: todo para los usuarios pero sin los usuarios. Tweet

  • SOA Checklist

    - by pat.shepherd
    In a recent meeting, the customer brought up a valid question: “How do I know if a problem/system is a good candidate for using SOA (vs. using old but trusted techniques).  I put this checklist together.  If you can answer yes to 2 or more of these, it might well be a good candidate.  This is V1, and I will likely update it over time.  Comments (that are not spam or sales pitches) appreciated. Part of the conversation was also around the fact that SOA has two faces to it; one is around the obvious reuse possibilities. The other, that often gets forgotten, is that SOA provides goodness in terms of simplifying integration even where opportunities to reuse those integrations are small; at least the integrations are standards-based and more flexible.  I did not write a lot of verbiage about each of them, for example “Business Process” implies that there is a set of step-wise actions that need to take place in a coordinated fashion that include integrating with systems (and sometimes people for approvals and other human-only actions) in the process.

  • Dynamic Data Connections

    - by Tim Dexter
    I have had a long running email thread running between Dan and David over at Valspar and myself. They have built some impressive connectivity between their in house apps and BIP using web services. The crux of their problem has been that they have multiple databases that need the same report executed against them. Not such an unusual request as I have spoken to two customers in the last month with the same situation. Of course, you could create a report against each data connection and just run or call the appropriate report. Not too bad if you have two or three data connections but more than that and it becomes a maintenance nightmare having to update queries or layouts. Ideally you want to have just a single report definition on the BIP server and to dynamically set the connection to be used at runtime based on the user or system that the user is in. A quick bit of digging and help from Shinji on the development team and I had an answer. Rather embarassingly, the solution has been around since the Oct 2010 rollup patch last year. Still, I grabbed the latest Jan 2011 patch - check out Note 797057.1 for the latest available patches. Once installed, I used the best web service testing tool I have yet to come across - SoapUI. Just point it at the WSDL and you can check out the available services and their parameters and then test them too. The XML packet has a new dynamic data source entry. You can set you own custom JDBC connection or just specify an existing data source name thats defined on the server. <pub:runReport> <pub:reportRequest> <pub:attributeFormat>xml</pub:attributeFormat> <pub:attributeTemplate>0</pub:attributeTemplate> <pub:byPassCache>true</pub:byPassCache> <pub:dynamicDataSource> <pub:JDBCDataSource> <pub:JDBCDriverClass></pub:JDBCDriverClass> <pub:JDBCDriverType></pub:JDBCDriverType> <pub:JDBCPassword></pub:JDBCPassword> <pub:JDBCURL></pub:JDBCURL> <pub:JDBCUserName></pub:JDBCUserName> <pub:dataSourceName>Conn1</pub:dataSourceName> </pub:JDBCDataSource> </pub:dynamicDataSource> <pub:reportAbsolutePath>/Test/Employee Report/Employee Report.xdo</pub:reportAbsolutePath> </pub:reportRequest> <pub:userID>Administrator</pub:userID> <pub:password>Administrator</pub:password> </pub:runReport> So I have Conn1 and Conn2 defined that are connections to different databases. I can just flip the name, make the WS call and get the appropriate dataset in my report. Just as an example, here's my web service call java code. Just a case of bringing in the BIP java libs to my java project. publicReportServiceService = new PublicReportServiceService(); PublicReportService publicReportService = publicReportServiceService.getPublicReportService_v11(); String userID = "Administrator"; String password = "Administrator"; ReportRequest rr = new ReportRequest(); rr.setAttributeFormat("xml"); rr.setAttributeTemplate("1"); rr.setByPassCache(true); rr.setReportAbsolutePath("/Test/Employee Report/Employee Report.xdo"); rr.setReportOutputPath("c:\\temp\\output.xml"); BIPDataSource bipds = new BIPDataSource(); JDBCDataSource jds = new JDBCDataSource(); jds.setDataSourceName("Conn1"); bipds.setJDBCDataSource(jds); rr.setDynamicDataSource(bipds); try { publicReportService.runReport(rr, userID, password); } catch (InvalidParametersException e) { e.printStackTrace(); } catch (AccessDeniedException e) { e.printStackTrace(); } catch (OperationFailedException e) { e.printStackTrace(); } } Note, Im no java whiz kid or whizzy old bloke, at least not unless Ive had a coffee. JDeveloper has a nice feature where you point it at the WSDL and it creates everything to support your calling code for you. Couple of things to remember: 1. When you call the service, remember to set the bypass the cache option. Forget it and much scratching of your head and taking my name in vain will ensue. 2. My demo actually hit the same database but used two users, one accessed the base tables another views with the same name. For far too long I thought the connection swapping was not working. I was getting the same results for both users until I realized I was specifying the schema name for the table/view in my query e.g. select * from EMP.EMPLOYEES. So remember to have a generic query that will depend entirely on the connection. Its a neat feature if you want to be able to switch connections and only define a single report and call it remotely. Now if you want the connection to be set dynamically based on the user and the report run via the user interface, thats going to be more tricky ... need to think about that one!

  • Windows not showing version (or other resources) for files in tooltip

    - by Synetech
    Whenever I hover the mouse cursor over executable file types (.exe, .dll, etc.) in Windows Explorer, it only shows the Type, Size, and (Modified) Date of the file in the tooltip instead of the Company, Version, Description, etc. This used to work in Windows XP, but Windows 7 is showing me less information which is frustrating because I often need that information to be quickly and easily available (no, opening the Properties dialog or adding columns is not a solution). How can I get Explorer to show me all the relevant information for the files in the tooltip? (Bonus points for also showing it in the Preview pane at the bottom.)

  • BIP Debugging to a file

    - by Tim Dexter
    If you use the standalone server or with OBIEE and use OC4J as the web server. Have you ever taken a looksee at the console window (doc/xterm) that you use to start it. Ever turned on debugging to see masses of info flow by that window and want to capture it all? I have been debugging today and watched all that info fly by and on Windoze gets lost before you can see it! The BIP developers use the System.out.println() and System.err.println()methods in the BIP applications to generate debugging formation. Normally the output from these method calls go to the console where the OC4J process is started. However you can specify command line options when starting OC4J to direct the stdout and stderr output directly to files. The ?out and ?err parameters tell OC4J which file to direct the output to. All you need do is modify the oc4j.cmd file used to start BIP. I didnt get fancy and just plugged in the following to the file under the start section. I just modified the line: set CMDARGS=-config "%SERVER_XML%" -userThreads to set CMDARGS=-config "%SERVER_XML%" -out D:\BI\OracleBI\oc4j_bi\j2ee\home\log\oc4j.out -err D:\BI\OracleBI\oc4j_bi\j2ee\home\log\oc4j.err -userThreads Bounced the server and I now have a ballooning pair of debug files that I can pour over to my hearts content. The .out file appears to contain BIP only log info and the .err file, OBIEE messages. If you are using another web server to host BIP, just check out the user docs to find out how to get the log files to write. Note to self, remember to turn off the debug when Im done!
