  • SQL SERVER – CSVExpress and Quick Data Load

    - by pinaldave
    One of the newest ETL tools is CSVexpress.com.  This is a program that can quickly load any CSV file into ODBC compliant databases uses data integration.  For those of you familiar with databases and how they operate, the question that comes to mind might be what use this program will have in your life. I have written earlier article on this subject over here SQL SERVER – Import CSV into Database – Transferring File Content into a Database Table using CSVexpress. You might know that RDBMS have automatic support for loading CSV files into tables – but it is not quite as easy as one click of a button.  First of all, most databases have a command line interface and you need the file and configuration script in order to load up.  You also need to know enough to write the script – which for novices can be extremely daunting.  On top of all this, if you work with more than one type of RDBMS, you need to know the ins and outs of uploading and writing script for more than one program. So you might begin to see how useful CSVexpress.com might be!  There are many other tools that enable uploading files to a database.  They can be very fancy – some can generate configuration files automatically, others load the data directly.  Again, novices will be able to tell you why these aren’t the most useful programs in the world.  You see, these programs were created with SQL in mind, not for uploading data.  If you don’t have large amounts of data to upload, getting the configurations right can be a long process and you will have to check the code that is generated yourself.  Not exactly “easy to use” for novices. That makes CSVexpress.com one of the best new tools available for everyone – but especially people who don’t want to learn a lot of new material all at once.  CSVexpress has an easy to navigate graphical user interface and no scripting or coding is required.  There are built-in constraints and data validations, and you can configure transforms and reject records right there on the screen.  But the best thing of all – it’s free! That’s right, you can download CSVexpress for free from www.csvexpress.com and start easily uploading and configuring riles almost immediately.  If you’re currently happy with your method of data configuration, keep up with the good work.  For the rest of us, there’s CSVexpress.com.

  • Programmatically Starting and Stopping FTP Sites in IIS 7 and IIS 8

    - by The Official Microsoft IIS Site
    I was recently contacted by someone who was trying to use Windows Management Instrumentation (WMI) code to stop and restart FTP websites by using code that he had written for IIS 6.0; his code was something similar to the following: Option Explicit On Error Resume Next Dim objWMIService, colItems, objItem ' Attach to the IIS service. Set objWMIService = GetObject( "winmgmts:\root\microsoftiisv2" ) ' Retrieve the collection of FTP sites. Set colItems = objWMIService.ExecQuery( "Select...(read more)

  • Establishing WebLogic Server HTTPS Trust of IIS Using a Microsoft Local Certificate Authority

    - by user647124
    Everyone agrees that self-signed and demo certificates for SSL and HTTPS should never be used in production and preferred not to be used elsewhere. Most self-signed and demo certificates are provided by vendors with the intention that they are used only to integrate within the same environment. In a vendor’s perfect world all application servers in a given enterprise are from the same vendor, which makes this lack of interoperability in a non-production environment an advantage. For us working in the real world, where not only do we not use a single vendor everywhere but have to make do with self-signed certificates for all but production, testing HTTPS between an IIS ASP.NET service provider and a WebLogic J2EE consumer application can be very frustrating to set up. It was for me, especially having found many blogs and discussion threads where various solutions were described but did not quite work and were all mostly similar but just a little bit different. To save both you and my future (who always seems to forget the hardest-won lessons) all of the pain and suffering, I am recording the steps that finally worked here for reference and sanity. How You Know You Need This The first cold clutches of dread that tells you it is going to be a long day is when you attempt to a WSDL published by IIS in WebLogic over HTTPS and you see the following: <Jul 30, 2012 2:51:31 PM EDT> <Warning> <Security> <BEA-090477> <Certificate chain received from myserver.mydomain.com - 10.555.55.123 was not trusted causing SSL handshake failure.> weblogic.wsee.wsdl.WsdlException: Failed to read wsdl file from url due to -- javax.net.ssl.SSLKeyException: [Security:090477]Certificate chain received from myserver02.mydomain.com - 10.555.55.123 was not trusted causing SSL handshake failure. The above is what started a three day sojourn into searching for a solution. Even people who had solved it before would tell me how they did, and then shrug when I demonstrated that the steps did not end in the success they claimed I would experience. Rather than torture you with the details of everything I did that did not work, here is what finally did work. Export the Certificates from IE First, take the offending WSDL URL and paste it into IE (if you have an internal Microsoft CA, you have IE, even if you don’t use it in favor of some other browser). To state the semi-obvious, if you received the error above there is a certificate configured for the IIS host of the service and the SSL port has been configured properly. Otherwise there would be a different error, usually about the site not found or connection failed. Once the WSDL loads, to the right of the address bar there will be a lock icon. Click the lock and then click View Certificates in the resulting dialog (if you do not have a lock icon but do have a Certificate Error message, see http://support.microsoft.com/kb/931850 for steps to install the certificate then you can continue from the point of finding the lock icon). Figure 1: View Certificates in IE Next, select the Details tab in the resulting dialog Figure 2: Use Certificate Details to Export Certificate Click Copy to File, then Next, then select the Base-64 encoded option for the format Figure 3: Select the Base-64 encoded option for the format For the sake of simplicity, I choose to save this to the root of the WebLogic domain. It will work from anywhere, but later you will need to type in the full path rather than just the certificate name if you save it elsewhere. Figure 4: Browse to Save Location Figure 5: Save the Certificate to the Domain Root for Convenience This is the point where I ran into some confusion. Some articles mentioned exporting the entire chain of certificates. This supposedly works for some types of certificates, or if you have a few other tools and the time to learn them. For the SSL experts out there, they already have these tools, know how to use them well, and should not be wasting their time reading this article meant for folks who just want to get things wired up and back to unit testing and development. For the rest of us, the easiest way to make sure things will work is to just export all the links in the chain individually and let WebLogic Server worry about re-assembling them into a chain (which it does quite nicely). While perhaps not the most elegant solution, the multi-step process is easy to repeat and uses only tools that are immediately available and require no learning curve. So… Next, go to Tools then Internet Options then the Content tab and click Certificates. Go to the Trust Root Certificate Authorities tab and find the certificate root for your Microsoft CA cert (look for the Issuer of the certificate you exported earlier). Figure 6: Trusted Root Certification Authorities Tab Export this one the same way as before, with a different name Figure 7: Use a Unique Name for Each Certificate Repeat this once more for the Intermediate Certificate tab. Import the Certificates to the WebLogic Domain Now, open an command prompt, navigate to [WEBLOGIC_DOMAIN_ROOT]\bin and execute setDomainEnv. You should then be in the root of the domain. If not, CD to the domain root. Assuming you saved the certificate in the domain root, execute the following: keytool -importcert -alias [ALIAS-1] -trustcacerts -file [FULL PATH TO .CER 1] -keystore truststore.jks -storepass [PASSWORD] An example with the variables filled in is: keytool -importcert -alias IIS-1 -trustcacerts -file microsftcert.cer -keystore truststore.jks -storepass password After several lines out output you will be prompted with: Trust this certificate? [no]: The correct answer is ‘yes’ (minus the quotes, of course). You’ll you know you were successful if the response is: Certificate was added to keystore If not, check your typing, as that is generally the source of an error at this point. Repeat this for all three of the certificates you exported, changing the [ALIAS-1] and [FULL PATH TO .CER 1] value each time. For example: keytool -importcert -alias IIS-1 -trustcacerts -file microsftcert.cer -keystore truststore.jks -storepass password keytool -importcert -alias IIS-2 -trustcacerts -file microsftcertRoot.cer -keystore truststore.jks -storepass password keytool -importcert -alias IIS-3 -trustcacerts -file microsftcertIntermediate.cer -keystore truststore.jks -storepass password In the above we created a new JKS key store. You can re-use an existing one by changing the name of the JKS file to one you already have and change the password to the one that matches that JKS file. For the DemoTrust.jks  that is included with WebLogic the password is DemoTrustKeyStorePassPhrase. An example here would be: keytool -importcert -alias IIS-1 -trustcacerts -file microsoft.cer -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase keytool -importcert -alias IIS-2 -trustcacerts -file microsoftRoot.cer -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase keytool -importcert -alias IIS-2 -trustcacerts -file microsoftInter.cer -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase Whichever keystore you use, you can check your work with: keytool -list -keystore truststore.jks -storepass password Where “truststore.jks” and “password” can be replaced appropriately if necessary. The output will look something like this: Figure 8: Output from keytool -list -keystore Update the WebLogic Keystore Configuration If you used an existing keystore rather than creating a new one, you can restart your WebLogic Server and skip the rest of this section. For those of us who created a new one because that is the instructions we found online… Next, we need to tell WebLogic to use the JKS file (truststore.jks) we just created. Log in to the WebLogic Server Administration Console and navigate to Servers > AdminServer > Configuration > Keystores. Scroll down to “Custom Trust Keystore:” and change the value to “truststore.jks” and the value of “Custom Trust Keystore Passphrase:” and “Confirm Custom Trust Keystore Passphrase:” to the password you used when earlier, then save your changes. You will get a nice message similar to the following: Figure 9: To Be Safe, Restart Anyways The “No restarts are necessary” is somewhat of an exaggeration. If you want to be able to use the keystore you may need restart the server(s). To save myself aggravation, I always do. Your mileage may vary. Conclusion That should get you there. If there are some erroneous steps included for your situation in particular, I will offer up a semi-apology as the process described above does not take long at all and if there is one step that could be dropped from it, is still much faster than trying to figure this out from other sources.

  • New security configuration flag in UCM PS3

    - by kyle.hatlestad
    While the recent Patch Set 3 (PS3) release was mostly focused on bug fixes and such, a new configuration flag was added for security. In 10gR3 and prior versions, UCM had a component called Collaboration Manager which allowed for project folders to be created and groups of users assigned as members to collaborate on documents. With this component came access control lists (ACL) for content and folders. Users could assign specific security rights on each and every document and folder within a project. And it was possible to enable these ACL's without having the Collaboration Manager component enabled. But it took some special instructions (see technote# 603148.1) and added some extraneous pieces still related to Collaboration Manager. When 11g came out, Collaboration Manager was no longer available. But the configuration settings to turn on ACLs were still there. Well, in PS3 they've been cleaned up a bit and a new configuration flag has been added to simply turn on the ACL fields and none of the other collaboration bits. To enable ACLs: UseEntitySecurity=true Along with this configuration flag to turn ACLs on, you also need to define which Security Groups will honor the ACL fields. If an ACL is applied to a content item with a Security Group outside this list, it will be ignored. SpecialAuthGroups=HumanResources,Legal,Marketing Save the settings and restart the instance. Upon restart, two new metadata fields will be created: xClbraUserList, xClbraAliasList. If you are using OracleTextSearch as the search indexer, be sure to run a Fast Rebuild on the collection. On the Check In, Search, and Update pages, values are added by simply typing in the value and getting a type-ahead list of possible values. Select the value, click Add and then set the level of access (Read, Write, Delete, or Admin). If all of the fields are blank, then it simply falls back to just Security Group and Account access. As for how they are stored in the metadata fields, each entry starts with it's identifier: ampersand (&) symbol for users, "at" (@) symbol for groups, and colon (:) for roles. Following that is the entity name. And at the end is the level of access in paranthesis. e.g. (RWDA). And each entry is separated by a comma. So if you were populating values through batch loader or an external source, the values would be defined this way. Detailed information on Access Control Lists can be found in the Oracle Fusion Middleware System Administrator's Guide for Oracle Content Server.

  • How does a programmer who doesn't know how to program get a job ? [closed]

    - by A programmer
    I often read about this and I'm curious: if there programmers who can't program, how did they get a programming job in the first place? They must bring some value to the company they're working for, otherwise they would be fired. I don't think "programmers who don't know how to program" means "bad programmers" in this case ? Even if they are bad programmers, they still know (badly) how to write (bad) programs. So what defines programmers who can't program ?

  • Gnome Do does not autostart and save shortcuts

    - by Matt
    For some reason the autostart of Gnome-Do will not work in 11.10. I've installed Gnome-Do via the Ubuntu Software Center. Then I changed the shortcut to launch Gnome-Do and marked the option to autostart Gnome-Do within Gnome-Do. In order to verify the autostart, I checked whether it's also found in the autostart applications (which it was). However, upon every restart I have to start Gnome-Do manually via the unity launcher and change the shortcut again.

  • PHP usage outside the web?

    - by Anto
    As you probably are aware, PHP is not only usable for web programming, but also desktop programming. It even has things such as GTK bindings. Do you have any examples of places where PHP is actually used outside web programming for anything more than just very trivial programs? Do you know of any desktop program which uses PHP to some extent (e.g. as Python could be used in a C program)? Note: I don't program in PHP myself, I'm just curious

  • Update to 13.10: blank screen and repeated suspend on wake from suspend

    - by user208026
    After updating from 13.04 to 13.10, intermittently when awaking from suspend, my screen will blink to black screen a few times, offer a login screen, and then go back to suspend unexpectedly. This will repeat each time I subsequently awake it from suspend. Only a restart will escape the suspend loop. This issue arose in tandem with the already raised issue regarding networking not restarting on wake from suspend, though appears to be distinct from that issue.

  • Is Unix/Linux adoption a measure of developer skill? [closed]

    - by adeptsage
    Is Linux/Unix based OS adoption for development (or recreation) a rough measure of the awareness, adaptability and/or skill of a developer, after considering factors like learning curve for effective code testing via the CLI, basic scripting, tweaking, etc. I have no intention of starting flame wars between Windows and Linux as better dev environments, and personal choice of OSes for dev, but what i do wish to know is that - will the level of adaptability of a person who uses a Unix based system be defined by the fact that he programs on a Unix based OS?

  • Why does Chrome video performance substantially degrade after waking from suspend in 10.10?

    - by Grant Heaslip
    Note: For some more details, some of which may not be true given what I've figured out, see this post. When I first boot my computer, video performance (both native H.264 HTML5 in YouTube and Vimeo, and in Flash) in Chrome is perfectly reasonable. CPU usage stays slow, everything works correctly, and the video is silky-smooth. But for whatever reason, if I suspend my computer then wake it up, video performance plummets. Full screen HTML5 video is choppy at best, and full-screen Flash video basically brings my computer to its knees (I'm talking less than a frame a second, and a 5 second lead time to leave full-screen after hitting Esc). Restarting Chrome doesn't fix this — I need to completely restart my machine before performance goes back to normal. Video performance in other applications, such as Movie Player, doesn't seem to be affected at all by the suspend cycle — it's only Chrome. I'm using a Lenovo X201, with an Intel GMA HD graphics chipset, and Intel compnents all around (I don't need any proprietary drivers). This didn't happen in 10.04, and I haven't anything that I think would have caused this to happen. It's possible that a Chrome release could have caused this, but it seems less likely than a regression between 10.04 and 10.10. Any ideas? EDIT: In response Georg's comment, logging in and out doesn't fix it. Restarting Compiz or switching to Metacity (at least by using "compiz/metacity --replace & disown" — am I doing it right?) doesn't help (actually, it seemed to help somewhat with Flash once, but I haven't been able to reproduce this). I'm not sure about GDM — when I use "sudo restart gdm" I get kicked back to the Linux shell (?), which I have no idea how to get out of. Also, I want to make very clear that this isn't just a case of Flash sucking (it does,but that's beside the point). I"m seeing the same general problem with HTML5 videos, and Flash is performing better on my Nexus One than it does on my Core i5 laptop. There's something screwy going on with Chrome and/or 10.10.
