Here is another example of one of the latest improvements: Contract Lifecycle Management for Public Sector, or CLM. The latest EBS module geared specifically for the Federal acquisition community. Our existing customers have been asking Oracle for years to upgrade its Advanced Procurement Suite to meet the complex procurement processes of the Federal Government. You asked; we listened. Oracle, with direct input from Federal agencies, subject matter experts, integration partners, and the Federal acquisition community, has expanded and deepened its procurement suite to meet the unique demands of the Federal acquisition community. New benefits/features include: Contract Line Item/Sub-Line Item (CLIN/SLIN) structures Configurable Document Numbering Complex Pricing Contract Types ( as per FAR Part 16) Option lines and exercising of options Incremental Funding capability Support for multiple document types (delivery orders, BPA call orders, awards, agreements, IDIQ contracts) Requisition lines to fund modifications Workload assignment and milestones Contract Action Reporting to FPDS-NG I’ve been conducting many tests over the past few months and have been quite impressed with the depth of features and the seamless integration to Federal Financials, specifically the funds control within the financials. Again, thank you for reading. If you have suggestions for future posts, please leave them in the comments section and I’ll take it from there.

  • Using Network load balancing to distribute load for SharePoint2010 – Part3 of building my own development SharePoint2010 Farm

    - by ybbest
    Part1 of building my own development SharePoint2010 Farm Part2 of building my own development SharePoint2010 Farm Part3 of building my own development SharePoint2010 Farm In my last post, I have installed SharePoint2010 in one of the server (WFE One) and configured using the OOB SharePoint configuration wizard. In this post I will show you how to use OOB windows network load balancing to distribute load for SharePoint2010 site. 1. Install SharePoint in another server WFE Two (you can follow the steps in my last post), but instead of choosing create new Farm, you need to select “connect to existing farm” this time. 2. Click next then click retrieve database names button and select the farm configuration database. 3. Click next and enter the passphrase you specified when you first installed the SharePoint Farm. 4. Click the advanced settings and select Use this machine to host the web site. 5. Click OK to finish the configurations 6. Next, Install NLB in the two WFE (web front end) SharePoint servers 7. Configure NLB to create the cluster. Go to Start—Administrative Tools—Network Load Balancing Manager 8. Right-click the Network Load Balancing Clusters Node and select New Cluster. 9. Type in the host name that is to be part of the new cluster. 10. Type in the IP address for the cluster. 11. Select the Multicast for this cluster.(The default one is Unicast) 12. You can configure the Port Rules for the clustering , but I will leave the default here. 13. Add another WEF to the cluster. 14. Type in the host name that is to be part of the new cluster. 15. Set the Priority to 2. 16. Click Next to complete the cluster setup. 17. Create an entry in the DNS for the new cluster. 18. Add the binding to the IIS site in the IIS Manager 19. Change the Alternate access mapping for you default site collection from http://sp2010wefone to http://team 20. Browse to http://Team , you will be redirected to the SharePoint site.

  • Cron job running successfully suddenly reports script is not found

    - by Ted B
    What might cause cron to suddenly report a file it is supposed to run is "not found," when the file hasn't been touched, and in fact, the entire system hasn't been touched since it last ran successfully? I have a cronjob schedule I define by doing sudo crontab -e In it, I have dozens of cron jobs that run successfully.. I do not have a PATH specified, and I use absolute paths to call all my scheduled scripts, setting the PATH in them as needed. I do not specify a SHELL in the crontab. All scripts identify the shell as their first line. Without me touching the system, a particular job defined in the middle of other jobs will suddenly stop running. To debug this, I added an output redirection to a log file. In that, the output clearly shows the output of the script successfully running time after time for weeks, and then suddenly the following appears: /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found If I do the ls command, copying and pasting that exact path from the error message, it clearly reports the file is still there (no surprise). Yet the log continues to report that file is "not found" until I take action. I can run the script manually and it runs just fine. If I do sudo crontab -e and save the file, the job runs on the next scheduled time, putting its output in the log, no longer reporting the script is "not found". It seems to me the contents of the script trying to be run are irrelevant since cron doesn't even process the file because it is "not found". I have a job scheduled below the one that is encountering this problem that I know is continuing to run, because I have its output mailed to me. So I know cron is running and continues to run at least one other job, even after it suddenly reports this job's script is "not found". All my lines end with a newline. I had no periods in the crontab until I added the redirection to a log file. I have now added a PATH specification, but left the absolute paths in the jobs. Unfortunately, I have no idea if and when this problem will occur. It will likely be weeks from now. By the way, I am running a script to syncronize the clock, and I see the time is exactly what it should be.

  • SpringMvc java.lang.NullPointerException When Posting Form To Server [closed]

    - by dev_darin
    I have a form with a user name field on it when i tab out of the field i use a RESTFUL Web Service that makes a call to a handler method in the controller. The method makes a call to a DAO class that checks the database if the user name exists. This works fine, however when the form is posted to the server i call the same exact function i would call in the handler method however i get a java.lang.NullPointerException when it accesses the class that makes a call to the DAO object. So it does not even access the DAO object the second time. I have exception handlers around the calls in all my classes that makes calls. Any ideas as to whats happening here why i would get the java.lang.NullPointerException the second time the function is called.Does this have anything to do with Spring instantiating DAO classes using a Singleton method or something to that effect? What can be done to resolve this? This is what happens the First Time The Method is called using the Web Service(this is suppose to happen): 13011 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - Inside jdbcOfficersDAO 13031 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL query 13034 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL statement [SELECT userName FROM crimetrack.tblofficers WHERE userName = ?] 13071 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Fetching JDBC Connection from DataSource 13496 [http-8084-2] DEBUG org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [adminz], value class [java.lang.String], SQL type unknown 13534 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Returning JDBC Connection to DataSource 13537 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - No username was found in exception 13537 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz does NOT exist The Second time When The Form Is 'Post' and a validation method handles the form and calls the same method the web service would call: 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - UserName is not null so going to check if its valid for :adminz 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - User Name in try.....catch block is adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - Inside Do UserNameExist about to validate with username : adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz EXCEPTION OCCURED java.lang.NullPointerException ValidateUserNameManager.java public class ValidateUserNameManager implements ValidateUserNameIFace { private OfficersDAO officerDao;

I am going to link it to a database at the backend. I want an alternative or equivalent software that will provide me with similar drag-and-drop feature enabled programing and GUI designing that will help me crate an application that will run on Windows.

  • Using Alt-select in SSMS, Word, and elsewhere

    - by John Paul Cook
    A surprising number of database people and Windows users in general don’t know about Alt select . This is a Windows technique not unique to SSMS that allows a user to select an arbitrary rectangular region of text and delete it, cut it, or copy it. Where I find Alt select particularly useful in SSMS is when I have a bunch of inline comments that are too far to the right. I want to delete much of the whitespace in front of them to move them to the left without disturbing any of the rest of the T-SQL....(read more)

  • Accessing SQL Server data from iOS apps

    - by RobertChipperfield
    Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

  • Avoiding connection timeouts on first connection to LocalDB edition of SQL Server Express

    - by Greg Low
    When you first make a connection to the new LocalDB edition of SQL Server Express, the system files, etc. that are required for a new version are spun up. (The system files such as the master database files, etc. end up in C:\Users\<username>\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\LocalDBApp1) That can take a while on a slower machine, so this means that the default connection timeout of 30 seconds (in most client libraries) could be exceeded. To avoid this hit on the...(read more)

    Noemi Moreno, Red Gate Business Intelligence Specialist Software vendors – even Microsoft – tend to forget about the needs of business intelligence developers. We are a rare and rather invisible species. For example, BIDS remained in VS 2008 until SQL Server 2012. It took until this release before we got something as simple as an “undo” function. Before I joined Red Gate as a BI specialist, I worked on SQL Development. I’ll never forget the time I discovered Red Gate’s SQL Compare tool and how it reduced the task of preparing a database release from a couple of days to ten minutes. When I moved to SSAS, MDX and cubes, I became frustrated with the deployment process because I couldn’t find a tool that made Cube releases as easy as they are with SQL Compare. This became my quest. I pitched the idea to a few people in Red Gate’s regular Down Tools Week, when everyone puts down their day-to-day tasks and works on their own projects. My task was to reason with a roomful of cynical developers, hardened to the blandishments of project managers, for help to develop a tool that would compare two different SSAS databases and create the script to process only the objects that needed processing, thereby reducing release time to only a few minutes. I walked to the podium and gave them the full story of the distressed BI specialists, doomed to spend tedious hours preparing deployment scripts. A few developers recovered from their torpor to cast a languid eye at my presentation. It wasn’t enough. In a sudden impulse, I blurted out a promise to perform a flamenco dance for just the team if the tool was able to successfully compare two SSAS databases and generate a script by the end of the week. I was lucky enough that some of them believed me and jumped in: David Pond (Dev), Matt Burton (Dev), Tilman Bregler (Dev), Shobana Sekar (Test), Ruchija Raj (Test), Nick Sutherland (Product Manager) and Irma Tanovic (BI). They didn’t know that Irma and I would be away on a conference in Amsterdam and would leave them without our support. But to my surprise, they had a working tool by the time we came back – basic, and with a few bugs, but a working tool nonetheless! Seeing it compare a very basic SSAS database, detect the changes and generate the scripts was amazing! Something that normally takes half a day was done in under a minute. Since then, a few months have passed and a BI Tools team has been created at Red Gate to work full time on BI tools for BI developers, starting with SSAS Compare. How cool is that? So download the free beta and give us your feedback. And the flamenco? I still need to deliver that. Tilman reminds me every day! I need to get the full flamenco costume.

  • Avoid SQL Injection with Parameters

    - by simonsabin
    The best way to avoid SQL Injection is with parameters. With parameters you can’t get SQL Injection. You only get SQL Injection where you are building a SQL statement by concatenating your parameter values in with your SQL statement. Annoyingly many TSQL statements don’t take parameters, CREATE DATABASE for instance, or really annoyingly ALTER USER. In these situations you have to rely on using QUOTENAME or REPLACE to avoid SQL Injection. (Kimberly Tripp takes about this in her recent blog post Little...(read more)
