• Uninstall, Disable, or Remove Windows 7 Media Center

  - by Mysticgeek

  Although Windows 7 Media Center has improved a lot over previous versions of Windows, but you might want to disable it for different reasons. Here we take a look at a couple of methods to get rid of it. There are a variety of reasons you might want to disable Windows 7 Media Center. Maybe you own a business and don’t want it to run on the machines. Or perhaps you don’t use it at all and just don’t want it around. Turn Off WMC Using Programs and Features Probably the easiest way to get rid of it on all versions of Windows 7 is to open Control Panel and select Programs and Features. This method is similar to disabling Internet Explorer 8 in Windows 7. On the left hand panel click on Turn Windows Features on or off. Scroll down to Media Features and expand the folder. Then Uncheck Windows Media Center… You’ll get a verification message making sure you want to disable it, click Yes. Then the box next to Windows Media Center will be empty…click OK. Wait while WMC is disabled… To complete the process a reboot is required. After getting back from the restart, the WMC icon will be gone and there won’t be any way to launch it. Re-enable WMC If you want to re-enable it, just go back in and recheck it. Again you’ll need to wait while it’s configured, but when it’s done, a restart is not required.   Disable Media Center Using Group Policy Note: This process uses Group Policy Editor which is not available in Home versions of Windows 7. Click on the Start menu and type gpedit.msc into the Search box and hit Enter. Now navigate to User Configuration \ Administrative Templates \ Windows Components \ Windows Media Center. Double-click on Do not allow Windows Media Center to run. Then select the radio button next to Enabled, click OK and close out of Group Policy Editor. Now if a user tries to launch WMC they will get the following message. Conclusion If you’re not a fan of Windows Media Center or want to disable it for whatever reason, the process is simple and there are a couple of ways you can do it. WMC is not included in Starter or Home Basic versions of Windows 7. If you’re new to Windows 7 Media Center, you might want to check out our guide on getting started and setting up live TV.

• How to create (via installer script) a task that will install my bash script so it runs on DE startup?

  - by MountainX

  I've been reading for the last couple hours about Upstart, .xinitrc, .xsessions, rc.local, /etc/init.d/, /etc/xdg/autostart, @reboot in crontab and so many other things that I'm totally confused! Here is my bash script. It should start/run after the desktop environment is started and it should continue to run at all times until logout/shutdown. It should start again on reboot. Any time the DE is running, it should run. #!/bin/bash while true; do if [[ -s ~/.updateNotification.txt ]]; then read MSG < ~/.updateNotification.txt kdialog --title 'The software has been updated' --msgbox "$MSG" cat /dev/null > ~/.updateNotification.txt fi sleep 3600 done exit 0 I know zero about using Upstart, but I understand that Upstart is one way to handle this. I'll consider other approaches but most of the things I've been reading about are too complex for me. Furthermore, I can't figure out which approach will meet my requirements (which I'll detail below). There are two steps in my question: How to automatically start the script above, as described above. How to "install" that Upstart task via a bash script (i.e., my "installer"). I assume (or hope) that step 2 is almost trivial once I understand step 1. I have to support all flavors of Ubuntu desktops. Therefore, the kdialog call above will be replaced. I'm considering easybashgui for this. (Or I could use zenity on gnome DE's.) My requirements are: The setup process (installation) must be done via a bash script. I cannot use the GUI method described in the Ubuntu doc AddingProgramToSessionStartup, for example. I must be able to script/automate the setup (installing) process using bash. Currently, it is as simple as having the bash installer script copy the above script into /home/$USER/.kde/Autostart/ The setup process must be universal across Ubuntu derivatives including Unity and KDE and gnome desktops. The same setup script (installer) should run on Linux Mint, Kubuntu, Xbuntu (basically any flavor of Ubuntu and major derivatives such as Linux Mint). For example, we cannot continue to put a script file in /home/$USER/.kde/Autostart/ because that exists only on KDE. The above script should work for each of the limited flavors we use. Hence our interest in using easybashgui instead of kdialog or zenity. See below. The installed monitoring script should only be started after the desktop is started since it will display a GUI message to the user if the update is found. The monitoring script (above) should run without root privileges, of course. But the installer (bash script) can be run as root. I'm not a real developer or a sysadmin. This is a part time volunteer thing for me, so it needs to be easy/simple. I can write bash scripts and I can program a little, but I know nothing about Upstart or systemd, for example. And, unfortunately, my job doesn't give me time to become an expert on init systems or much of anything else related to development and sysadmin. So I have to stick with simple solutions. The easybashgui version of the script might look like this: #!/bin/bash source easybashgui while true; do if [[ -s ~/.updateNotification.txt ]]; then read MSG < ~/.updateNotification.txt message "$MSG" cat /dev/null > ~/.updateNotification.txt fi sleep 3600 done exit 0

• DAC pack up all your troubles

  - by Tony Davis

  Visual Studio 2010, or perhaps its apparently-forthcoming sister, "SQL Studio", is being geared up to become the natural way for developers to create databases. Central to this drive is the introduction of 'data-tier application components', or DACs. Applications are developed as normal but when it comes to deployment, instead of supplying the DBA with a bunch of scripts to create the required database objects, the developer creates a single DAC Package ("DAC Pack"); a zipped XML file containing all the database objects needed by the application, along with versioning information, policies for deployment, and so on. It's an intriguing prospect. Developers can work on their development database using their existing tools and source control, and then package up the changes into a single DACPAC for deployment and management. DBAs get an "application level view" of how their instances are being used and the ability to collectively, rather than individually, manage the objects. The DBA needing to manage a large number of relatively small databases can use "DAC snapshots" to get a quick overview of what has changed across all the databases they manage. The reason that DAC packs haven't caused more excitement is that they can only be pushed to SQL Server 2008 R2, and they must be developed or inspected using Visual Studio 2010. Furthermore, what we see right now in VS2010 is more of a 'work-in-progress' or 'vision of the future', with serious shortcomings and restrictions that render it unsuitable for anything but small 'non-critical' departmental databases. The first problem is that DAC packs support a limited set of schema objects (corresponding closely to the features available on 'Azure'). This means that Service Broker queues, CLR Objects, and perhaps most critically security (permissions, certificates etc.), are off-limits. Applications that require these objects will need to add them via a post-deployment TSQL script, rather defeating the whole idea. More worrying still is the process for altering a database with a DAC pack. The grand 'collective' philosophy, whereby a single XML file can be used for deploying and managing builds and changes, extends, unfortunately, to database upgrades. Any change to a database object will result in the creation of a new database, copying the data from the old version, nuking the previous one, and then renaming the new one. Simple eh? The problem is that even something as trivial as adding a comment to a stored procedure in a 5GB database will require the server to find at least twice as much space, as well sufficient elbow-room in the transaction log for copying the largest table. Of course, you'll need to take the database offline for the full course of the deployment, which is likely to take a long time if there is a lot of data. This upgrade/rename process breaks the log chain, makes any subsequent full restore operation highly complicated, and will also break log shipping. As with any grand vision, the devil is always in the detail. It's hard to fathom why Microsoft hasn't used a SQL Compare-style approach to the upgrade process, altering a database with a change script, and this will surely be adopted in the near future. Something had to be in place for VS2010, but right now DAC packs only make sense for Azure. For this, they're cute, but hardly compelling. Nevertheless, DBAs would do well to get familiar with VS 2010 and DAC packs. Like it or not, they're both coming. Cheers, Tony.

  WEBCAST THURSDAY!! 03/22/12 Do you need to lower costs? Raise Productivity? Foster Innovation? Improve Online Engagement? But you’re still stuck with Documentum? Step away from the ledge – there is hope – let us help you. Top 4 Content Imperatives · Lower Costs - Reduce labor, maintenance fees, storage and electrical consumption · Raise Productivity - Automation and integration, communication, findability · Foster Innovation - Enable collaboration, expertise location · Improve Online Engagement – enable user-driven, dynamic marketing initiatives With the coming technology wave we see four content imperatives. Every organization has had to reduce costs, cost cutting has become a way of life. Everyone is working three jobs as positions are eliminated. And so we have to reduce labor, reduce maintenance, and reduce money we are wasting on things like storing content that is redundant or no longer useful. We also, to fill that gap, need to raise productivity. Knowledge workers represent the fastest growing segment of the workforce, accounting for 40%-75% of the employees at organizations in sectors like financial services, life sciences, healthcare and retail.  What’s more, their wages total 18 percent of the United States GDP. And so we can’t afford information systems that don’t let our top performers be the best they can be. We look to automate the content processes, provide ways to integrate that content into our processes, provide communication to make decisions, and to make content more findable so people can make the right decision and move the process forward. And really to get ourselves out of the current financial status, we can only cut costs so far. We have to innovate out of economic tough times – to find new products and new markets. And to enable the innovation process, we have to enable collaboration and expertise location. So much of innovation is about building on innovations that have come before. To solve problems, we have to be able to find what our organization has already created. We find that problems we need to solve have already been solved if we can find the right document, the right person. So we have to provide systems that enable us to stand on the shoulders of our organization’s accomplishments. Good content drives great marketing. Online engagement is growing as an absolute necessity for modern growing marketing organizations that require the business users be enabled for dynamic marketing content creation, updates and targeted content creation and management. Unfortunately – if you are currently stuck with Documentum, you are really lacking in your Web Experience Management capabilities. Documentum previously used FatWire for web publishing. Now FatWire is part of Oracle. Oracle provides powerful web engagement capabilities: Increase sales and loyalty by optimizing online engagement Create, manage and moderate contextually relevant, targeted and interactive online experiences Optimize customer engagement across, web, mobile and social channels Manage large scale multichannel global online presence with integration to enterprise applications Enable business users to control their content and make their own updates Publish content from native files – enable navigation of project documents, procedures, policy information Enable content display and updates from existing web applications – one click to drag and drop content management functionality So you get the ability to self-publish information and make it navigable, to move the process of publishing from IT to business users, and the ability to address a whole new area of user engagement with web experience management. So… if you are still stuck with Documentum and don’t know what to do – contact us – not only will Oracle help you step away from the ledge, but also with the MoveOff Documentum program, we are offering you a way – trade-in your Documentum licenses for a 100% credit on Oracle WebCenter.

• Deploying an SSL Application to Windows Azure &ndash; The Dark Secret

  - by ToStringTheory

  When working on an application that had been in production for some time, but was about to have a shopping cart added to it, the necessity for SSL certificates came up.  When ordering the certificates through the vendor, the certificate signing request (CSR) was generated through the providers (http://register.com) web interface, and within a day, we had our certificate. At first, I thought that the certification process would be the hard part…  Little did I know that my fun was just beginning… The Problem I’ll be honest, I had never really secured a site before with SSL.  This was a learning experience for me in the first place, but little did I know that I would be learning more than the simple procedure.  I understood a bit about SSL already, the mechanisms in how it works – the secure handshake, CA’s, chains, etc…  What I didn’t realize was the importance of the CSR in the whole process.  Apparently, when the CSR is created, a public key is created at the same time, as well as a private key that is stored locally on the PC that generated the request.  When the certificate comes back and you import it back into IIS (assuming you used IIS to generate the CSR), all of the information is combined together and the SSL certificate is added into your store. Since at the time the certificate had been ordered for our site, the selection to use the online interface to generate the CSR was chosen, the certificate came back to us in 5 separate files: A root certificate – (*.crt file) An intermediate certifcate – (*.crt file) Another intermediate certificate – (*.crt file) The SSL certificate for our site – (*.crt file) The private key for our certificate – (*.key file) Well, in case you don’t know much about Windows Azure and SSL certificates, the first thing you should learn is that certificates can only be uploaded to Azure if they are in a PFX package – securable by a password.  Also, in the case of our SSL certificate, you need to include the Private Key with the file.  As you can see, we didn’t have a PFX file to upload. If you don’t get the simple PFX from your hosting provider, but rather the multiple files, you will soon find out that the process has turned from something that should be simple – to one that borders on a circle of hell… Probably between the fifth and seventh somewhere… The Solution The solution is to take the files that make up the certificates chain and key, and combine them into a file that can be imported into your local computers store, as well as uploaded to Windows Azure.  I can not take the credit for this information, as I simply researched a while before finding out how to do this. Download the OpenSSL for Windows toolkit (Win32 OpenSSL v1.0.1c) Install the OpenSSL for Windows toolkit Download and move all of your certificate files to an easily accessible location (you'll be pointing to them in the command prompt, so I put them in a subdirectory of the OpenSSL installation) Open a command prompt Navigate to the folder where you installed OpenSSL Run the following command: openssl pkcs12 -export –out {outcert.pfx} –inkey {keyfile.key}      –in {sslcert.crt} –certfile {ca1.crt} –certfile (ca2.crt) From this command, you will get a file, outcert.pfx, with the sum total of your ssl certificate (sslcert.crt), private key {keyfile.key}, and as many CA/chain files as you need {ca1.crt, ca2.crt}. Taking this file, you can then import it into your own IIS in one operation, instead of importing each certificate individually.  You can also upload the PFX to Azure, and once you add the SSL certificate links to the cloud project in Visual Studio, your good to go! Conclusion When I first looked around for a solution to this problem, there were not many places online that had the information that I was looking for.  While what I ended up having to do may seem obvious, it isn’t for everyone, and I hope that this can at least help one developer out there solve the problem without hours of work!

• Converting a PV vm back into an HVM vm

  - by wim.coekaerts

  I have been doing some Oracle VM benchmark stuff in the last week or 2 in my off hours and yesterday I wanted to convert one of my VMs that was based on a paravirt kernel into a vm that just boots as a regular hardware virt VM with a standard x86-64 kernel. It took me a little while to figure out the fastest way so now that I have it pretty much down I wanted to share the steps. A PV kernel uses pygrub and a paravirt kernel image that lives on the vm image virtual disk. since this disk image does not have to be bootable it doesn't contain a boot sector and if you just restart the VM in hvm mode the virtual bios will just not do much as it can't start the boot process from disk The first thing I do is make a backup of my vm.cfg file :-) and then edit it as follows : the original file contains : bootloader = '/usr/bin/pygrub' I replace that with : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' kernel = '/usr/lib/xen/boot/hvmloader' then changing the disk files. I change my xvd disks to hd disks and I copy over the iso image of my instal lDVD. In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

• How to ace Skype Interviews

  Many companies these days opt to include a Skype interview in the recruitment process, as it comes close to a face-to-face interview without the time and costs involved for both the company and the candidate. In some cases during the recruitment process at Oracle you also might be asked to conduct a Skype interview. To help you get started with this, we researched some websites to give you several tips and tricks. What most of the bloggers say about this topic is collected in this article to help you prepare. It is all about Technology The bit that can make a Skype interview more complicated than a face-to-face or phone interview is the fact you are using additional technology. Always check the video and audio capabilities of your computer to make sure they work properly. Be prepared for connections to be limited during the interview. Using a webcam can also be confusing, if you do not have a lot of experience using it. Make sure you look at the camera and not the monitor to avoid the impression you are looking away. Practice If you do not feel comfortable using the camera, do a mock interview with a friend or family member before you have the actual interview. Be aware that facial impressions or reactions come across differently on a monitor, so make sure to practice how you  come across during the interview. Good lighting in the room also helps you make you look the best for the interviewer. You and your room Dress code, as in any face-to-face interview,is important to think about. Dress the same way as you would for face-to-face interviews and avoid patterns or informal clothing. Another tip,is to be aware of your surroundings. Make sure the room you use looks good on camera, making sure it is neat and tidy, also think about how the walls look behind you. Also make sure you do not get distracted during the interview by anyone or anything, as this will directly have an impact on your interview and your ability to focus and concentrate. What is in a name What goes for any account that you share during the recruitment process, either your email address or Skype name, is to make sure it comes across as professional. Try to avoid using nicknames or strange words in your accounts, stick to using a first name – last name or an abbreviation of the same. If you would like to read more about this topic, have a look at the links below which we used as inspiration for this blog article. 7 Deadly Skype Interview Sins is fun to read and to gives you some good advice to keep in mind. ·         http://www.inc.com/guides/201103/4-tips-for-conducting-a-job-interview-using-skype.html ·         http://blog.simplyhired.com/2012/05/5-tips-to-a-great-skype-interview.html ·         http://www.cnn.com/2011/LIVING/07/11/skype.interview.tips.cb/index.html http://www.ehow.com/how_5648281_prepare-skype-interview.html

• Managing Operational Risk of Financial Services Processes – part 1/ 2

  - by Sanjeevio

  Financial institutions view compliance as a regulatory burden that incurs a high initial capital outlay and recurring costs. By its very nature regulation takes a prescriptive, common-for-all, approach to managing financial and non-financial risk. Needless to say, no longer does mere compliance with regulation will lead to sustainable differentiation.  Genuine competitive advantage will stem from being able to cope with innovation demands of the present economic environment while meeting compliance goals with regulatory mandates in a faster and cost-efficient manner. Let’s first take a look at the key factors that are limiting the pursuit of the above goal. Regulatory requirements are growing, driven in-part by revisions to existing mandates in line with cross-border, pan-geographic, nature of financial value chains today and more so by frequent systemic failures that have destabilized the financial markets and the global economy over the last decade.  In addition to the increase in regulation, financial institutions are faced with pressures of regulatory overlap and regulatory conflict. Regulatory overlap arises primarily from two things: firstly, due to the blurring of boundaries between lines-of-businesses with complex organizational structures and secondly, due to varying requirements of jurisdictional directives across geographic boundaries e.g. a securities firm with operations in US and EU would be subject different requirements of “Know-Your-Customer” (KYC) as per the PATRIOT ACT in US and MiFiD in EU. Another consequence and concomitance of regulatory change is regulatory conflict, which again, arises primarily from two things: firstly, due to diametrically opposite priorities of line-of-business and secondly, due to tension that regulatory requirements create between shareholders interests of tighter due-diligence and customer concerns of privacy. For instance, Customer Due Diligence (CDD) as per KYC requires eliciting detailed information from customers to prevent illegal activities such as money-laundering, terrorist financing or identity theft. While new customers are still more likely to comply with such stringent background checks at time of account opening, existing customers baulk at such practices as a breach of trust and privacy. As mentioned earlier regulatory compliance addresses both financial and non-financial risks. Operational risk is a non-financial risk that stems from business execution and spans people, processes, systems and information. Operational risk arising from financial processes in particular transcends other sources of such risk. Let’s look at the factors underpinning the operational risk of financial processes. The rapid pace of innovation and geographic expansion of financial institutions has resulted in proliferation and ad-hoc evolution of back-office, mid-office and front-office processes. This has had two serious implications on increasing the operational risk of financial processes: ·         Inconsistency of processes across lines-of-business, customer channels and product/service offerings. This makes it harder for the risk function to enforce a standardized risk methodology and in turn breaches harder to detect. ·         The proliferation of processes coupled with increasingly frequent change-cycles has resulted in accidental breaches and increased vulnerability to regulatory inadequacies. In summary, regulatory growth (including overlap and conflict) coupled with process proliferation and inconsistency is driving process compliance complexity In my next post I will address the implications of this process complexity on financial institutions and outline the role of BPM in lowering specific aspects of operational risk of financial processes.

• Accounts in Work Items after migration to TFS 2010 and to new domain

  - by Clara Oscura

  Lately I’ve been doing some tests on migrating our TFS 2008 installation to TFS 2010, coupled with a machine and domain change. One particular topic that was tricky is user accounts. We installed first a new machine with TFS 2010 and then migrated the projects in the old server. The work items were migrated with the projects. Great, but if I try to edit one of the old work items I cannot save it anymore because some fields contain old user names (ex. OLDDOMAIN\user) which are not known in the new domain (it should be NEWDOMAIN\user). The errors look like this: When I correct the ‘Assigned To’ field value, I get another error regarding another field: Before TFS 2010, we had TFSUsers power tool. It allow you to map an old user name to a new user name. This is not available anymore because WI fields with user accounts are now synchronized with AD display names changes (explained here). The correct way to go about this in TFS 2010 is to use TFSConfig Identities before adding the new domain accounts into the TFS groups (documented here). So, too late for us. I’ve found a (tedious) workaround to change those old account in work items in order to allow people to keep working with them. 1. Install TFS 2010 power tools 2. Export WIT from your project (VS | Tools | Process Editor | Work Item Types). Save the definition, for example: Original_MyProject_Task.xml 3. Copy the xml (NoReadOnly_MyProject_Task.xml) and edit it. From the field definition of ‘Activated By’, ‘Closed By’ and ‘Resolved By’, remove the following:        <WHENNOTCHANGED field="System.State">           <READONLY />         </WHENNOTCHANGED> 4. Import WIT in VS. Choose the new file (NoReadOnly_MyProject_Task.xml) and import it in MyProject 5. Open all tasks in Excel (flat list). Display the following columns: Asssigned To Activated By Closed By Resolved By Change the user accounts to the new ones (I usually sort each column alphabetically to make it easier). 6. Publish. If you get a conflict on a field, tough luck. You will have to manually choose “Local version” for each work item. I told you it was a tedious process. 7. Import original WIT (Original_MyProject_Task.xml) in MyProject. We only changed the WI definition so that we could change some fields. The original definition should be put back. And what about these other fields? Created By Authorized As These fields are not editable by definition (VS | Tools | Process Editor | Work Item Fields Explorer), even if they are not marked as read-only in the WIT. You can leave the old values. It doesn’t seem to matter to TFS. The other four fields are editable by definition, so only the WIT readonly rule prevents us from changing them.

• PowerShell: Read Excel to Create Inserts

  - by BuckWoody

  I’m writing a series of articles on how to migrate “departmental” data into SQL Server. I also hold workshops on the entire process – from discovering that the data exists to the modeling process and then how to design the Extract, Transform and Load (ETL) process. Finally I write about (and teach) a few methods on actually moving the data. One of those options is to use PowerShell. There are a lot of ways even with that choice, but the one I show is to read two columns from the spreadsheet and output statements that would insert the data using a stored procedure. Of course, you could re-write this as INSERT statements, out to a text file for bcp, or even use a database connection in the script to move the data directly from Excel into SQL Server. This snippet won’t run on your system, of course – it assumes a Microsoft Office Excel 2007 spreadsheet located at c:\temp called VendorList.xlsx. It looks for a tab in that spreadsheet called Vendors. The statement that does the writing just uses one column: Vendor Code. Here’s the breakdown of what I’m doing: In the first block, I connect to Microsoft Office Excel. That connection string is specific to Excel 2007, so if you need a different version you’ll need to look that up. In the second block I set up a selection from the entire spreadsheet based on that tab. Note that if you’re only after certain data you shouldn’t get the whole spreadsheet – that’s just good practice. In the next block I create the text I want, inserting the Vendor Code field as I go. Finally I close the connection. Enjoy! $ExcelConnection= New-Object -com "ADODB.Connection" $ExcelFile="c:\temp\VendorList.xlsx" $ExcelConnection.Open("Provider=Microsoft.ACE.OLEDB.12.0;` Data Source=$ExcelFile;Extended Properties=Excel 12.0;") $strQuery="Select * from [Vendors$]" $ExcelRecordSet=$ExcelConnection.Execute($strQuery) do { Write-Host "EXEC sp_InsertVendors '" $ExcelRecordSet.Fields.Item("Vendor Code").Value "'" $ExcelRecordSet.MoveNext()} Until ($ExcelRecordSet.EOF) $ExcelConnection.Close() Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary.

• Conflict Minerals - Design to Compliance

  - by C. Chadwick

  Dr. Christina  Schröder - Principal PLM Consultant, Enterprise PLM Solutions EMEA What does the Conflict Minerals regulation mean? Conflict Minerals has recently become a new buzz word in the manufacturing industry, particularly in electronics and medical devices. Known as the "Dodd-Frank Section 1502", this regulation requires SEC listed companies to declare the origin of certain minerals by 2014. The intention is to reduce the use of tantalum, tungsten, tin, and gold which originate from mines in the Democratic Republic of Congo (DRC) and adjoining countries that are controlled by violent armed militia abusing human rights. Manufacturers now request information from their suppliers to see if their raw materials are sourced from this region and which smelters are used to extract the metals from the minerals. A standardized questionnaire has been developed for this purpose (download and further information). Soon, even companies which are not directly affected by the Conflict Minerals legislation will have to collect and maintain this information since their customers will request the data from their suppliers. Furthermore, it is expected that the public opinion and consumer interests will force manufacturers to avoid the use of metals with questionable origin. Impact for existing products Several departments are involved in the process of collecting data and providing conflict minerals compliance information. For already marketed products, purchasing typically requests Conflict Minerals declarations from the suppliers. In order to address requests from customers, technical operations or product management are usually responsible for keeping track of all parts, raw materials and their suppliers so that the required information can be provided. For complex BOMs, it is very tedious to maintain complete, accurate, up-to-date, and traceable data. Any product change or new supplier can, in addition to all other implications, have an effect on the Conflict Minerals compliance status. Influence on product development  It makes sense to consider compliance early in the planning and design of new products. Companies should evaluate which metals are needed or contained in supplier parts and if these could originate from problematic sources. The answer influences the cost and risk analysis during the development. If it is known early on that a part could be non-compliant with respect to Conflict Minerals, alternatives can be evaluated and thus costly changes at a later stage can be avoided. Integrated compliance management  Ideally, compliance data for Conflict Minerals, but also for other regulations like REACH and RoHS, should be managed in an integrated supply chain system. The compliance status is directly visible across the entire BOM at any part level and for the finished product. If data is missing, a request to the supplier can be triggered right away without having to switch to another system. The entire process, from identification of the relevant parts, requesting information, handling responses, data entry, to compliance calculation is fully covered end-to-end while being transparent for all stakeholders. Agile PLM Product Governance and Compliance (PG&C) The PG&C module extends Agile PLM with exactly this integrated functionality. As with the entire Agile product suite, PG&C can be configured according to customer requirements: data fields, attributes, workflows, routing, notifications, and permissions, etc… can be quickly and easily tailored to a customer’s needs. Optionally, external databases can be interfaced to query commercially available sources of Conflict Minerals declarations which obviates the need for a separate supplier request in many cases. Suppliers can access the system directly for data entry through a special portal. The responses to the standard EICC-GeSI questionnaire can be imported by the supplier or internally. Manual data entry is also supported. A set of compliance-specific dashboards and reports complement the functionality Conclusion  The increasing number of product compliance regulations, for which Conflict Minerals is just one example, requires companies to implement an efficient data and process management in this area. Consumer awareness in this matter increases as well so that an integrated system from development to production also provides a competitive advantage.

• Why We Do What We Do. (Part 3 of 5 Part Series on JDE 5G Postponed)

  - by Kem Butller-Oracle

  By Lyle Ekdahl - Oracle JD Edwards Sr. VP General Manager  In the closing of part two of this 5 part blog series, I stated that in the next installment I would explore the expected results of the digital overdrive era and the impact it will have on our economy. While I have full intentions of writing on that topic, I am inspired today to write about something that is top of mind. It’s top of mind because it has come up several times recently conversations with my Oracle’s JD Edwards team members, with customers and our partners, plus I feel passionately about why I do what I do…. It is not what we do but why we do that thing that we do Do you know what you do? For the most part, I bet you could tell me what you do even if your work has changed over the years.  My real question is, “Do you get excited about what you do, and are you fulfilled? Does your work deliver a sense of purpose, a cause to work for, and something to believe in?”  Alright, I guess that was not a single question. So let me just ask, “Why?” Why are you here, right now? Why do you get up in the morning? Why do you go to work? Of course, I can’t answer those questions for you but I can share with you my POV.   For starters, there are several things that drive me. As many of you know by now, I have a somewhat competitive nature but it is not solely the thrill of winning that actually fuels me. Now don’t get me wrong, I do like winning occasionally. However winning is only a potential result of competing and is clearly not guaranteed. So why compete? Why compete in business, and particularly why in this Enterprise Software business?  Here’s why! I am fascinated by creative and building processes. It is about making or producing things, causing something to come into existence. With the right skill, imagination and determination, whether it’s art or invention; the result can deliver value and inspire. In both avocation and vocation I always gravitate towards the create/build processes.  I believe one of the skills necessary for the create/build process is not just the aptitude but also, and especially, the desire and attitude that drives one to gain a deeper understanding. The more I learn about our customers, the more I seek to understand what makes the successful and what difficult issues cause them to struggle. I like to look for the complex, non-commodity process problems where streamlined design and modern technology can provide an easy and simple solution. It is especially gratifying to see our customers use our software to increase their own ability to deliver value to the market. What an incredible network effect! I know many of you share this customer obsession as well as the create/build addiction focused on simple and elegant design. This is what I believe is at the root of our common culture.  Are JD Edwards customers on a whole different than other ERP solutions’ customers? I would argue that for the most part, yes, they are. They selected our software, and our software is different. Why? Because I believe that the create/build process will generally result in solutions that reflect who built it and their culture. And a culture of people focused on why they create/build will attract different customers than one that is based on what is built or how the solution is delivered. In the past I have referred to this idea as character of the customer, and it transcends industry, size and run rate. Now some would argue that JD Edwards has some customers who are characters. But that is for a different post. As I have told you before, the JD Edwards culture is unique, and its resulting economy is valuable and deserving of our best efforts.

• Part 6: Extensions vs. Modifications

  - by volker.eckardt(at)oracle.com

  Customizations = Extensions + Modifications In the EBS terminology, a customization can be an extension or a modification. Extension means that you mainly create your own code from scratch. You may utilize existing views, packages and java classes, but your code is unique. Modifications are quite different, because here you take existing code and change or enhance certain areas to achieve a slightly different behavior. Important is that it doesn't matter if you place your code at the same or at another place – it is a modification. It is also not relevant if you leave the original code enabled or not! Why? Here is the answer: In case the original code piece you have taken as your base will get patched, you need to copy the source again and apply all your changes once more. If you don't do that, you may get different results or write different data compared to the standard – this causes a high risk! Here are some guidelines how to reduce the risk: Invest a bit longer when searching for objects to select data from. Rather choose a view than a table. In case Oracle development changes the underlying tables, the view will be more stable and is therefore a better choice. Choose rather public APIs over internal APIs. Same background as before: although internal structure might change, the public API is more stable. Use personalization and substitution rather than modification. Spend more time to check if the requirement can be covered with such techniques. Build a project code library, avoid that colleagues creating similar functionality multiple times. Otherwise you have to review lots of similar code to determine the need for correction. Use the technique of “flagged files”. Flagged files is a way to mark a standard deployment file. If you run the patch analyse (within Application Manager), the analyse result will list flagged standard files in case they will be patched. If you maintain a cross reference to your own CEMLIs, you can easily determine which CEMLIs have to be reviewed. Implement a code review process. This can be done by utilizing team internal or external persons. If you implement such a team internal process, your team members will come up with suggestions how to improve the code quality by themselves. Review heavy customizations regularly, to identify options to reduce complexity; let's say perform this every 6th month. You may not spend days for such a review, but a high level cross check if the customization can be reduced is suggested. De-install customizations which are no more required. Define a process for this. Add a section into the technical documentation how to uninstall and what are possible implications. Maintain a cross reference between CEMLIs and between CEMLIs, EBS modules and business processes. Keep this list up to date! Share this list! By following these guidelines, you are able to improve product stability. Although we might not be able to avoid modifications completely, we can give a much better advise to developers and to our test team. Summary: Extensions and Modifications have to be handled differently during their lifecycle. Modifications implicate a much higher risk and should therefore be reviewed more frequently. Good cross references allow you to give clear advise for the testing activities.

• Development Quirk From ASP.NET Dynamic Compilation

  - by jkauffman

  The Problem I got a compilation error in my ASP.NET MVC3 project that tested my sanity today. (As always, names are changed to protect the innocent) The type or namespace name 'FishViewModel' does not exist in the namespace 'Company.Product.Application.Models' (are you missing an assembly reference?) Sure looks easy! There must be something in the project referring to a FishViewModel. The Confusing Part The first thing I noticed was the that error was occuring in a folder clearly not in my project and in files that I definitely had not created: %SystemRoot%\Microsoft.NET\Framework\(versionNumber)\Temporary ASP.NET Files\ App_Web_mezpfjae.1.cs I also ascertained these facts, each of which made me more confused than the last: Rebuild and Clean had no effect. No controllers in the project ever returned a ViewResult using FishViewModel. No views in the project defined that they use FishViewModel. Searching across all files included in the project for “FishViewModel” provided no results. The build server did not report a problem. The Solution The problem stemmed from a file that was not included in the project but still present on the file system: (By the way, if you don’t know this trick already, there is a toolbar button in the Solution Explorer window to “Show All Files” which allows you to see files all files in the file system) In my situation, I was working on the mission-critical Fish view before abandoning the feature. Instead of deleting the file, I excluded it from the project. However, this was a bad move. It caused the build failure, and in order to fix the error, this file must be deleted. By the way, this file was not in source control, so the build server did not have it. This explains why my build server did not report a problem for me. The Explanation So, what’s going on? This file isn’t even a part of the project, so why is it failing the build? This is a behavior of the ASP.NET Dynamic Compilation. This is the same process that occurs when deploying a webpage; ASP.NET compiles the web application’s code. When this occurs on a production server, it has to do so without the .csproj file (which isn’t usually deployed, if you’ve taken your time to do a deployment cleanly). This process has merely the file system available to identify what to compile. So, back in the world of developing the webpage in visual studio on my developer box, I run into the situation because the same process is occuring there. This is true even though I have more files on my machine than will actually get deployed. I can’t help but think that this error could be attributed back to the real culprit file (Fish.cshtml, rather than the temporary files) with some work, but at least the error had enough information in it to narrow it down. The Conclusion I had previously been accustomed to the idea that for c# projects, the .csproj file always “defines” the build behavior. This investigation has taught me that I’ll need to shift my thinking a bit to remember that the file system has the final say when it comes to web applications, even on the developer’s machine!

• Hyper-V for Developers Part 1 Internal Networks

  Over the last year, weve been working with Microsoft to build training and demo content for the next version of Office Communications Server code-named Microsoft Communications Server 14.  This involved building multi-server demo environments in Hyper-V, getting them running on demo servers which we took to TechEd, PDC, and other training events, and sometimes connecting the demo servers to the show networks at those events.  ITPro stuff that should scare the hell out of a developer! It can get ugly when I occasionally have to venture into ITPro land.  Lets leave it at that. Having gone through this process about 10 to 15 times in the last year, I finally have it down.  This blog series is my attempt to put all that knowledge in one place if anything, so I can find it somewhere when I need it again.  Ill start with the most simple scenario and then build on top of it in future blog posts. If youre an ITPro, please resist the urge to laugh at how trivial this is. Internal Hyper-V Networks Lets start simple.  An internal network is one that intended only for the virtual machines that are going to be on that network it enables them to communicate with each other. Create an Internal Network On your host machine, fire up the Hyper-V Manager and click the Virtual Network Manager in the Actions panel. Select Internal and leave all the other default values. Give the virtual network a name, and leave all the other default values. After the virtual network is created, open the Network and Sharing Center and click Change Adapter Settings to see the list of network connections. The only thing I recommend that you do is to give this connection a friendly label, e.g. Hyper-V Internal.  When you have multiple networks and virtual networks on the host machines, this helps group the networks so you can easily differentiate them from each other.  Otherwise, dont touch it, only bad things can happen. Connect the Virtual Machines to the Internal Network Im assuming that you have more than 1 virtual machine already configured in Hyper-V, for example a Domain Controller, and Exchange Server, and a SharePoint Server. What you need to do is basically plug in the network to the virtual machine.  In order to do this, the machine needs to have a virtual network adapter.  If the VM doesnt have a network adapter, open the VMs Settings and click Add Hardware in the left pane.  Choose the virtual network to which to bind the adapter to. If you already have a virtual network adapter on the VM, simply connect it to the virtual network. Assign IP Addresses to the Virtual Machines on the Internal Network Open the Network and Sharing Center on your VM, there should only be 1 network at this time.  Open the Properties of the connection, select Internet Protocol Version 4 (TCP/IPv4) and hit Properties. In this environment, Im assigning IP addresses as 192.168.0.xxx.  This particular VM has an IP address of 192.168.0.40 with a subnet mask of 255.255.255.0, and a DNS Server of 192.168.0.18.  DNS is running on the Domain Controller VM which has an IP address of 192.168.0.18. Repeat this process on every VM in your environment, obviously assigning a unique IP address to each.  In an environment with a domain controller, you should now be able to ping the machines from each other. What Next? After completing this process, heres what you still cannot do: Access the internet from any of the VMs Remote desktop to a VM from the host Remote desktop to a VM over the network In the next post, well take a look configuring an External network adapter on the virtual machines.  Well then build on top of that so that you can RDP into the VMs from the host machine and over the network.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Parameterized StreamInsight Queries

  - by Roman Schindlauer

  The changes in our APIs enable a set of scenarios that were either not possible before or could only be achieved through workarounds. One such use case that people ask about frequently is the ability to parameterize a query and instantiate it with different values instead of re-deploying the entire statement. I’ll demonstrate how to do this in StreamInsight 2.1 and combine it with a method of using subjects for dynamic query composition in a mini-series of (at least) two blog articles. Let’s start with something really simple: I want to deploy a windowed aggregate to a StreamInsight server, and later use it with different window sizes. The LINQ statement for such an aggregate is very straightforward and familiar: var result = from win in stream.TumblingWindow(TimeSpan.FromSeconds(5))               select win.Avg(e => e.Value); Obviously, we had to use an existing input stream object as well as a concrete TimeSpan value. If we want to be able to re-use this construct, we can define it as a IQStreamable: var avg = myApp     .DefineStreamable((IQStreamable<SourcePayload> s, TimeSpan w) =>         from win in s.TumblingWindow(w)         select win.Avg(e => e.Value)); The DefineStreamable API lets us define a function, in our case from a IQStreamable (the input stream) and a TimeSpan (the window length) to an IQStreamable (the result). We can then use it like a function, with the input stream and the window length as parameters: var result = avg(stream, TimeSpan.FromSeconds(5)); Nice, but you might ask: what does this save me, except from writing my own extension method? Well, in addition to defining the IQStreamable function, you can actually deploy it to the server, to make it re-usable by another process! When we deploy an artifact in V2.1, we give it a name: var avg = myApp     .DefineStreamable((IQStreamable<SourcePayload> s, TimeSpan w) =>         from win in s.TumblingWindow(w)         select win.Avg(e => e.Value))     .Deploy("AverageQuery"); When connected to the same server, we can now use that name to retrieve the IQStreamable and use it with our own parameters: var averageQuery = myApp     .GetStreamable<IQStreamable<SourcePayload>, TimeSpan, double>("AverageQuery"); var result = averageQuery(stream, TimeSpan.FromSeconds(5)); Convenient, isn’t it? Keep in mind that, even though the function “AverageQuery” is deployed to the server, its logic will still be instantiated into each process when the process is created. The advantage here is being able to deploy that function, so another client who wants to use it doesn’t need to ask the author for the code or assembly, but just needs to know the name of deployed entity. A few words on the function signature of GetStreamable: the last type parameter (here: double) is the payload type of the result, not the actual result stream’s type itself. The returned object is a function from IQStreamable<SourcePayload> and TimeSpan to IQStreamable<double>. In the next article we will integrate this usage of IQStreamables with Subjects in StreamInsight, so stay tuned! Regards, The StreamInsight Team

• If the model is validating the data, shouldn't it throw exceptions on bad input?

  - by Carlos Campderrós

  Reading this SO question it seems that throwing exceptions for validating user input is frowned upon. But who should validate this data? In my applications, all validations are done in the business layer, because only the class itself really knows which values are valid for each one of its properties. If I were to copy the rules for validating a property to the controller, it is possible that the validation rules change and now there are two places where the modification should be made. Is my premise that validation should be done on the business layer wrong? What I do So my code usually ends up like this: <?php class Person { private $name; private $age; public function setName($n) { $n = trim($n); if (mb_strlen($n) == 0) { throw new ValidationException("Name cannot be empty"); } $this->name = $n; } public function setAge($a) { if (!is_int($a)) { if (!ctype_digit(trim($a))) { throw new ValidationException("Age $a is not valid"); } $a = (int)$a; } if ($a < 0 || $a > 150) { throw new ValidationException("Age $a is out of bounds"); } $this->age = $a; } // other getters, setters and methods } In the controller, I just pass the input data to the model, and catch thrown exceptions to show the error(s) to the user: <?php $person = new Person(); $errors = array(); // global try for all exceptions other than ValidationException try { // validation and process (if everything ok) try { $person->setAge($_POST['age']); } catch (ValidationException $e) { $errors['age'] = $e->getMessage(); } try { $person->setName($_POST['name']); } catch (ValidationException $e) { $errors['name'] = $e->getMessage(); } ... } catch (Exception $e) { // log the error, send 500 internal server error to the client // and finish the request } if (count($errors) == 0) { // process } else { showErrorsToUser($errors); } Is this a bad methodology? Alternate method Should maybe I create methods for isValidAge($a) that return true/false and then call them from the controller? <?php class Person { private $name; private $age; public function setName($n) { $n = trim($n); if ($this->isValidName($n)) { $this->name = $n; } else { throw new Exception("Invalid name"); } } public function setAge($a) { if ($this->isValidAge($a)) { $this->age = $a; } else { throw new Exception("Invalid age"); } } public function isValidName($n) { $n = trim($n); if (mb_strlen($n) == 0) { return false; } return true; } public function isValidAge($a) { if (!is_int($a)) { if (!ctype_digit(trim($a))) { return false; } $a = (int)$a; } if ($a < 0 || $a > 150) { return false; } return true; } // other getters, setters and methods } And the controller will be basically the same, just instead of try/catch there are now if/else: <?php $person = new Person(); $errors = array(); if ($person->isValidAge($age)) { $person->setAge($age); } catch (Exception $e) { $errors['age'] = "Invalid age"; } if ($person->isValidName($name)) { $person->setName($name); } catch (Exception $e) { $errors['name'] = "Invalid name"; } ... if (count($errors) == 0) { // process } else { showErrorsToUser($errors); } So, what should I do? I'm pretty happy with my original method, and my colleagues to whom I have showed it in general have liked it. Despite this, should I change to the alternate method? Or am I doing this terribly wrong and I should look for another way?

• Shrinking a Linux OEL 6 virtual Box image (vdi) hosted on Windows 7

  - by AndyBaker

  v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Recently for a customer demonstration there was a requirement to build a virtual box image with Oracle Enterprise Manager Cloud Control 12c. This meant installing OEL Linux 6 as well as creating an 11gr2 database and Oracle Enterprise Manager Cloud Control 12c on a single virtual box. Storage was sized at 300Gb using dynamically allocated storage for the virtual box and about 10Gb was used for Linux and the initial build. After copying over all the binaries and performing all the installations the virtual box became in the region of 80Gb used size on the host operating system, however internally it only really needed around 20Gb. This meant 60Gb had been used when copying over all the binaries and although now free was not returned to the host operating system due to the growth of the virtual box storage '.vdi' file.  Once the ‘vdi’ storage had grown it is not shrunk automatically afterwards. Space is always tight on the laptop so it was desirable to shrink the virtual box back to a minimal size and here is the process that was followed. Install 'zerofree' Linux package into the OEL6 virtual box The RPM was downloaded and installed from a site similar to below; http://rpm.pbone.net/index.php3/stat/4/idpl/12548724/com/zerofree-1.0.1-5.el5.i386.rpm.html A simple internet search for ’zerofree Linux rpm’ was easy to perform and find the required rpm. Execute 'zerofree' package on the desired Linux file system To execute this package the desired file system needs to be mounted read only. The following steps outline this process. As root: # umount /u01 As root:# mount –o ro –t ext4 /u01 NOTE: The –o is options and the –t is the file system type found in the /etc/fstab. Next run zerofree against the required storage, this is located by a simple ‘df –h’ command to see the device associated with the mount. As root:# zerofree –v /dev/sda11   NOTE: This takes a while to run but the ‘-v’ option gives feedback on the process. What does Zerofree do? Zerofree’s purpose is to go through the file system and zero out any unused sectors on the volume so that the later stages can shrink the virtual box storage obtaining the free space back. When zerofree has completed the virtual box can be shutdown as the last stage is performed on the physical host where the virtual box vdi files are located. Compact the virtual box ‘.vdi’ files The final stage is to get virtual box to shrink back the storage that has been correctly flagged as free space after executing zerofree. On the physical host in this case a windows 7 laptop a DOS window was opened. At the prompt the first step is to put the virtual box binaries onto the PATH. C:\ >echo %PATH%   The above shows the current value of the PATH environment variable. C:\ >set PATH=%PATH%;c:\program files\Oracle\Virtual Box;   The above adds onto the existing path the virtual box binary location. C:\>cd c:\Users\xxxx\OEL6.1   The above changes directory to where the VDI files are located for the required virtual box machine. C:\Users\xxxxx\OEL6.1>VBoxManage.exe modifyhd zzzzzz.vdi compact  NOTE: The zzzzzz.vdi is the name of the required vdi file to shrink. Finally the above command is executed to perform the compact operation on the ‘.vdi’ file(s). This also takes a long time to complete but shrinks the VDI file back to a minimum size. In the case of the demonstration virtual box OEM12c this reduced the virtual box to 20Gb from 80Gb which was a great outcome to achieve.

• Challenges in Corporate Reporting - New Independent Research

  - by ndwyouell

  Earlier this year, Oracle and Accenture sponsored a global study on trends in financial close and reporting. We surveyed 1,123 finance professionals in large organizations in 12 countries around the world during February and March. Financial Consolidation and Reporting is the most mature aspect of Enterprise Performance Management with mainstream solutions having been around for over 30 years. But of course over this time there have been many changes and very significant increases in regulation. So just what is the current state is Financial Consolidation and Reporting in our major corporations across the world? We commissioned this independent research to find out. Highlights of the result are: •          Seeking change: Businesses recognize they need to invest in financial reporting to address the challenges they currently face. 47 percent of companies have made substantial investments over the last year to the financial close, filing, and reporting processes. •          Ineffective investments: Despite these investments, spreadsheets (72 percent) and e-mails (68 percent) are still being used daily to track and manage reporting, suggesting that new investments are falling short of expectations. •          Increased costs and uncertainty: The situation is so opaque that managers across the finance function are unable to fully understand the financial impact or cost implications of reporting, with 60 percent of respondents admitting they did not know the total cost of managing and publicizing their financial results. •          Persistent challenges: 68 percent of respondents admitted that they have inadequate visibility into reporting processes, while 84 percent of finance managers surveyed said they find it difficult to control the quality of financial data across the entire reporting process. •          Decreased effectiveness: 71 percent of finance managers feel their effectiveness is limited in some way by data-analysis–related issues, while 39 percent of C-level or VP-level respondents say their effectiveness is impaired by limited visibility. •          Missed deadlines: Due to late changes to the chart of accounts, 15 percent of global businesses have missed statutory filings, putting their companies at risk of financial penalties and potentially impacting share value. The report makes it clear that investments made to date by these large organizations around the world have been uneven across the close, reporting, and filing processes, which has led to the challenges these organizations currently face in the overall process. Regardless of whether companies are using a variety of solutions or a single solution, the report shows they continue to witness increased costs, ineffectual data management, and missed reporting, which—in extreme circumstances—can impact a company’s corporate image and share value. The good news is that businesses realize that these problems persist and 86 percent of companies are likely to make a significant investment during the next five years to address these issues. While they should invest, it is critical that they direct investments correctly to address the key issues this research identified: •          Improving data integrity •          Optimizing processes •          Integrating the extended financial close process By addressing these issues and with clear guidance on how to implement the correct business processes, infrastructure, and software solutions, finance teams will find that their reporting processes are much more effective, cost-efficient, and aligned with their performance expectations.

• jqGrid (Delete row) - How to send additional POST data???

  - by ronanray

  Hi experts, I'm having problem with jqGrid delete mechanism as it only send "oper" and "id" parameters in form of POST data (id is the primary key of the table). The problem is, I need to delete a row based on the id and another column value, let's say user_id. How to add this user_id to the POST data??? I can summarize the issue as the following: How to get the cell value (user_id) of the selected row? AND, how to add that user_id to the POST data so it can be retrieved from the code behind where the actual delete process takes place. Sample codes: jQuery("#tags").jqGrid({ url: "subgrid.process.php, editurl: "subgrid.process.php?, datatype: "json", mtype: "POST", colNames:['id','user_id','status_type_id'], colModel:[{name:'id', index:'id', width:100, editable:true}, {name:'user_id', index:'user_id', width:200, editable:true}, {name:'status_type_id', index:'status_type_id', width:200} ], pager: '#pagernav2', rowNum:10, rowList:[10,20,30,40,50,100], sortname: 'id', sortorder: "asc", caption: "Test", height: 200 }); jQuery("#tags").jqGrid('navGrid','#pagernav2', {add:true,edit:false,del:true,search:false}, {}, {mtype:"POST",closeAfterAdd:true,reloadAfterSubmit:true}, // add options {mtype:"POST",reloadAfterSubmit:true}, // del options {} // search options ); Help....
