  • Student wanting to go to a developer conference

    - by Jamie Keeling
    I'm a 21 year old student in my last year of University, and I am looking for information about developer conferences. I live in Derby (United Kingdom) and there's not (As far as I know) many conferences local to where I live. I do have a car at my disposal so travelling shouldn't be a problem. I was hoping somebody could recommend the best way to go about finding and attending a conference, which one is probably the best to go to and what kind of things I'd need to know and take beforehand. I've done a couple of Google searches and searched SO itself but nothing specific to my needs was found. Note: I'm primarily a C# developer using WPF and WinForms but I'm open to pretty much anything.

  • Non-English Character Display in Oracle SQL Developer

    - by thatjeffsmith
    I get a variation on this question at least once a week, if not more frequently. I’m from Israel, and the language on the databases is Hebrew. When I use the old and deprecated SQL*Plus (windows rich client) I can see the hebrew clearly, when I use the latest SQL Developer, I get gibberish. This question appears on the forums about every week or so as well. So what’s the deal? Well, it starts with a basic misunderstanding of NLS Client parameters. These should accurately reflect the language and locality setup on your LOCAL machine. DO NOT COPY what’s set in the database. The these parameters work together with the database so that information can be transferred back and forth correctly. Having the wrong NLS parameters locally can be bad. [ORACLE DOCS]Setting the NLS_LANG parameter properly is essential to proper data conversion. The character set that is specified by the NLS_LANG parameter should reflect the setting for the client operating system. Setting NLS_LANG correctly enables proper conversion from the client operating system character encoding to the database character set. When these settings are the same, Oracle Database assumes that the data being sent or received is encoded in the same character set as the database character set, so character set validation or conversion may not be performed. This can lead to corrupt data if conversions are necessary. OK, so what are you supposed to do? Set the Font! 9 times out of 10, this preference fixes the problem with display issues. Make sure you set a Font that supports the characters you’re trying to display. It’s as simple as that. This preference defines the font used to display characters in the editors and the data grids. If you have it set to a font that doesn’t have Hebrew character support – you’re not going to see Hebrew in SQL Developer. A few years ago…wow, like 15 years ago, I learned that the Tohama Font is pretty Unicode-friendly. Bad Font Selection A Font that’s not non-English friendly Good Font Selection Exact same text, except rendered with the Tahoma font Summary Having problems seeing non-English text in SQL Developer? Check the font! And do not start messing with NLS parameters without talking to your DBA first.

  • SQL Developer Quick Tip: Reordering Columns

    - by thatjeffsmith
    Do you find yourself always scrolling and scrolling and scrolling to get to the column you want to see when looking at a table or view’s data? Don’t do that! Instead, just right-click on the column headers, select ‘Columns’, and reorder as desired. Access the Manage Columns dialog Then move up the columns you want to see first… Put them in the order you want – it won’t affect the database. Now I see the data I want to see, when I want to see it – no scrolling. This will only change how the data is displayed for you, and SQL Developer will remember this ordering until you ‘Delete Persisted Settings…’ What IS Remembered Via These ‘Persisted Settings?’ Column Widths Column Sorts Column Positions Find/Highlights This means if you manipulate one of these settings, SQL Developer will remember them the next time you open the tool and go to that table or view. Don’t know what I mean by ‘Find/Highlight?’ Find and highlight values in a grid with Ctrl+F

  • Oracle SQL Developer: Single Object Compare

    - by thatjeffsmith
    There’s a nasty rumor going around that you can’t compare database objects and/or code in Oracle SQL Developer. So let’s put that to bed right now. First, here’s how to compare: PL/SQL to PL/SQL or a SQL statement to another SQL statement So now that that’s settled, why don’t we take a look at how to compare a single table, to another table – whether it’s in the same database or a different database. Database Diff There’s no additional licensing requirement here. If you have SQL Developer, you can use this feature. if you’re going to compare 1 table to another, make sure you ONLY have ‘tables’ checked And then, use this dialog to select your table(s): Move over the object(s) you want to compare over to the right hand side. And now we can move onto the results. The differences, side-by-side, and the script to make B look like A Common lines with differences are highlighted in blue, new lines are highlighted in red. So that’s why they are different, but here’s the script to synch up the differences: Read the script, TEST the script, apply the script. And that’s it. Well, that’s mostly it. If you have questions about how to compare a database object in a schema you don’t have the login information for, read this post next.

  • Defaults for Exporting Data in Oracle SQL Developer

    - by thatjeffsmith
    I was testing a reported bug in SQL Developer today – so the bug I was looking for wasn’t there (YES!) but I found a different one (NO!) – and I was getting frustrated by having to check the same boxes over and over again. What I wanted was INSERT STATEMENTS to the CLIPBOARD. Not what I want! I’m always doing the same thing, over and over again. And I never go to FILE – that’s too permanent for my type of work. I either want stuff to the clipboard or to the worksheet. Surely there’s a way to tell SQL Developer how to behave? Oh yeah, check the preferences So you can set the defaults for this dialog. Go to: Tools – Preferences – Database – Utilities – Export Now I will always start with ‘INSERT’ and ‘Clipboard’ – woohoo! Now, I can also go INTO the preferences for each of the different formats to save me a few more clicks. I prefer pointy hats (^) for my delimiters, don’t you? So, spend a few minutes and set each of these to what you’re normally doing and save yourself a bunch of time going forward.

  • Oracle Database 12c By Example – SQL Developer and Multitenant

    - by thatjeffsmith
    As you may have heard, Oracle Database 12c is now available. In addition to the binaries and docs going out, we also published a few new Oracle By Example (OBE) chapters. You can find those links here on our product page. Do you know who found these, practically the minute they were published? An enterprising DBA-extraordinaire who was just happening to be presenting at the ODTUG KScope13 conference in New Orleans. He thought it would be a good idea to download the new software over a hotel WIFI, install and create a new multitenant database, watch a few OBEs, and then demo that live for his ‘SQL Developer for DBAs‘ session. Pretty crazy, right? Well, he did it, and I was there to watch. Way cool. You can listen to @leight0nn tell his story in his own words via this ODTUG interview with @oraclenered. In case you’re too giddy to sit through the video, I’ll give you a preview – he succesfully cloned a pluggable database in about a minute with only a couple of clicks using Oracle SQL Developer 3.2.20.09 while connected to a 12c database.

  • Oracle SQL Developer v3.2.1 Now Available

    - by thatjeffsmith
    Oracle SQL Developer version 3.2.1 is now available. I recommend that everyone now upgrade to this release. It features more than 200 bug fixes, tweaks, and polish applied to the 3.2 edition. The high profile bug fixes submitted by customers and users on our forums are listed in all their glory for your review. I want to highlight a few of the changes though, as I recognize many of you lack the time and/or patience to ‘read the docs.’ That would include me, which is why I enjoy writing these kinds of blog posts. I’m lazy – just like you! No more artificial line breaks between CREATE OR REPLACE and your PL/SQL In versions 3.2 and older, when you pull up your stored procedural objects in our editor, you would see a line break inserted between the CREATE OR REPLACE and then the body of your code. In version 3.2.1, we have removed the line break. 3.1 3.2.1 Trivia Did You Know? The database doesn’t store the ‘CREATE’ or ‘CREATE OR REPLACE’ bit of your PL/SQL code in the database. If we look at the USER_SOURCE view, we can see that the code begins with the object name. So the CREATE OR REPLACE bit is ‘artificial’ The intent is to give you the code necessary to recreate your object – and have it ‘compile’ into the database. We pretty much HAVE to add the ‘CREATE OR REPLACE.’ From now on it will appear inline with the first line of your code. Exporting Tables & Views When exporting data from your tables or views, previous versions of SQL Developer presented a 3 step wizard. It allows you to choose your columns and apply data filters for what is exported. This was kind of redundant. The grids already allowed you to select your columns and apply filters. Wouldn’t it be more intuitive AND efficient to just make the grids behave in a What You See Is What You Get (WYSIWYG) fashion? In version 3.2.1, that is exactly what will happen. The wizard now only has two steps and the grid will export the data and columns as defined in the visible grid. Let the grid properties define what is actually exported! And here is what is pasted into my worksheet: "BREWERY"|"CITY" "3 Brewers Restaurant Micro-Brewery"|"Toronto" "Amsterdam Brewing Co."|"Toronto" "Ball Brewing Company Ltd."|"Toronto" "Big Ram Brewing Company"|"Toronto" "Black Creek Historic Brewery"|"Toronto" "Black Oak Brewing"|"Toronto" "C'est What?"|"Toronto" "Cool Beer Brewing Company"|"Toronto" "Denison's Brewing"|"Toronto" "Duggan's Brewery"|"Toronto" "Feathers"|"Toronto" "Fermentations! - Danforth"|"Toronto" "Fermentations! - Mount Pleasant"|"Toronto" "Granite Brewery & Restaurant"|"Toronto" "Labatt's Breweries of Canada"|"Toronto" "Mill Street Brew Pub"|"Toronto" "Mill Street Brewery"|"Toronto" "Molson Breweries of Canada"|"Toronto" "Molson Brewery at Air Canada Centre"|"Toronto" "Pioneer Brewery Ltd."|"Toronto" "Post-Production Bistro"|"Toronto" "Rotterdam Brewing"|"Toronto" "Steam Whistle Brewing"|"Toronto" "Strand Brasserie"|"Toronto" "Upper Canada Brewing"|"Toronto" JUST what I wanted And One Last Thing Speaking of export, sometimes I want to send data to Excel. And sometimes I want to send multiple objects to Excel – to a single Excel file that is. In version 3.2.1 you can now do that. Let’s export the bulk of the HR schema to Excel, with each table going to it’s own workbook in the same worksheet. Select many tables, put them in in a single Excel worksheet If you try this in previous versions of SQL Developer it will just write the first table to the Excel file. This is one of the bugs we addressed in v3.2.1. Here is what the output Excel file looks like now: Many tables - Many workbooks in an Excel Worksheet I have a sneaky suspicion that this will be a frequently used feature going forward. Excel seems to be the cornerstone of many of our popular features. Imagine that!

  • How to create an SaaS Application?

    - by Andrew
    I don't know how else to say it so I'm just going to explain my ideal scenario and hopefully you can explain to me how to implement it... I'm creating an application with the Zend Framework that will be hosted with DreamHost. The application will be hosted on its own domain (i.e. example-app.com). Basically, a user should be able to sign up, get their own domain sampleuser.example-app.com or example-app.com/sampleuser which points to, what looks like their own instance of the app, which is really a single instance serving up different content based on the url. Eventually, I want my users to be able to create their own domain (like foobar.com) that points to sampleuser.example-app.com, such that visitors to foobar.com don't notice that the site is really being served up from example-app.com. I don't know how to do most of that stuff. How does this process work? Do I need to do some funky stuff with Apache or can this be done with a third party host, like DreamHost? Update: Thanks for the advice! I've decided to bite the bullet and upgrade my hosting plan to utilize wildcard subdomains. It's cheaper than I was expecting! I also found out about domain reseller programs, like opensrs.com, that have their own API. I think using one of these APIs will be the solution to my domain registration issue.

  • Best recruiting SaaS available for tech startups?

    - by ajhit406
    I run a small startup and am always on the lookout for quality engineers. I've seen someone solicit SO with a similar question but there was only one response so I'm going to solicit the community again. (http://stackoverflow.com/questions/112766/free-application-to-keep-track-of-a-recruiting-process didn't suffice for me) Over a long period of time, I've found that my system of recruiting is incredibly inefficient. An applicant who might have been attractive the first week might become overshadowed by other applicants further down the road. Sometimes, applicants who I ignored become relevant to a new position that opens up as an web app becomes more robust and takes a turn in a direction I didn't consider. These are all difficult to track. Knowing that recruiting intelligent people should be an ongoing process, what are the best web applications for managing the process? Are there any apps with features catered specifically towards tech startups? (Free or paid, doesn't matter).

  • SQL Developer Data Modeler v3.3 Early Adopter: Link Model Objects Across Designs

    - by thatjeffsmith
    The third post in our “What’s New in SQL Developer Data Modeler v3.3” series, SQL Developer Data Modeler now allows you to link objects across models. If you need to catch up on the earlier posts, here are the first two: New and Improved Search Collaborative Design via Excel Today’s post is a very simple and straightforward discussion on how to share objects across models and designs. In previous releases you could easily copy and paste objects between models and designs. Simply select your object, right-click and select ‘Copy’ Once copied, paste it into your other designs and then make changes as required. Once you paste the object, it is no longer associated with the source it was copied from. You are free to make any changes you want in the new location without affecting the source material. And it works the other way as well – make any changes to the source material and the new object is also unaffected. However. What if you want to LINK a model object instead of COPYING it? In version 3.3, you can now do this. Simply drag and drop the object instead of copy and pasting it. Select the object, in this case a relational model table, and drag it to your other model. It’s as simple as it sounds, here’s a little animated GIF to show you what I’m talking about. Drag and drop between models/designs to LINK an object Notes The ‘linked’ object cannot be modified from the destination space Updating the source object will propagate the changes forward to wherever it’s been linked You can drag a linked object to another design, so dragging from A - B and then from B - C will work Linked objects are annotated in the model with a ‘Chain’ bitmap, see below This object has been linked from another design/model and cannot be modified. A very simple feature, but I like the flexibility here. Copy and paste = new independent object. Drag and drop = linked object.

  • How are SaaS applications organized?

    - by tomekw
    Consider web (MVC, for example Rails) application for multiple clients as a service. How to design this? one application instance per client? (+ one database per client) one instance for all clients (+ one database for all clients) Former one is simple, but... "inefficient". How about the latter? (best practises, design patterns) How to separate client data? For example: worker "A" of client "1" has two documents, worker "B" of client "2" has three documents. How to build model associations to protect other users (and clients) data? I think joining every query with Client model is not a good solution.

  • Authentication for SaaS

    - by josh
    What would be recommended as an authentication solution for a Software-as-a-service product? Specifically, my product would have clients that would typically have low information technology skills, potentially not even having an IT department within their organization. I would still like to have my application authenticate against their internal directory service (eDirectory, Active Directory, etc.). I don't want them, however, to have to open/forward ports (for instance, opening up port 636 so I can do LDAPS binds directly to their directory service). One idea I had was to have an application installed on a server within their organization's network that would backconnect to my service. This would be a persistant socket. When I need to authenticate a user, I send the credentials via the socket (encrypted) - the application then performs a bind/whatever to authenticate against the directory service and replies with OK/FAIL. What would you suggest? My goal here is to essentially have the client install an application within their network, with very little configuration or intervention.

  • Apache/Tomcat configuration to allow multiple incoming DNS served by one app (SAAS)

    - by Shaun F
    Is there a way to setup apache and tomcat so that I can have d1.webapp.com d2.webapp.com d3.webapp.com etc. All hosted by the same tomcat instance without having to add aliases to the HOSTS element in the tomcat config file? I will be allowing new users to have thier own domain when they sign up and it will be a subdomain of the web app. I don't want to keep updating the hosts file for aliases and restarting tomcat though each time a new user signs up.

  • Managing Scripts in Oracle SQL Developer

    - by thatjeffsmith
    You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

  • Dealing with a developer continuously ignoring edge cases in his work

    - by Alex N.
    I have an interesting, fairly common I guess, issue with one of the developers in my team. The guy is a great developer, work fast and productive, produces fairly good quality code and all. Good engineer. But there is a problem with him - very often he fails to address edge cases in his code. We spoke with him about it many times and he is trying but I guess he just doesn't think this way. So what ends up happening is that QA would find plenty issues with his code and return it back for development again and again, ultimately resulting in missed deadlines and everyone in the team unhappy. I don't know what to do with him and how to help him overcome this problem. Perhaps someone with more experience could advise? Thank you!

  • Apple Developer Enterprise Program?

    - by Gnial0id
    I'm building an iOS application for a client (not an enterprise but non-profit association with under than 500 employess), distributed in a free version and a "paid" one. The free version will be available with iTunes/AppStore, no problem with that. But about the paid one... the distribution my client wants is different. They want to distribute it to their clients as a bonus in their subscription, and so, to control this distribution. The first answer would be "iOS Developer Enterprise Program", but it's not an enterprise and have less than 500 employees. Will the fact that my client will distribute the app' with a subscription be a problem ? I spend a lot of time to read documentation, but it is not very clear. I'm a bit lost, I admit it. Any help would grateful.

  • Oracle SQL Developer version 3.2.2 Released

    - by thatjeffsmith
    This is another maintenance release, but I don’t want to minimize the work done in either the 3.2.1 or the 3.2.2 editions. The two releases include more than 400 bug fixes. Version 3.2 should be rocking and rolling and good to go while we work on the next major release! You can find the downloads and bug fixes in the normal places: Download 3.2.2 Bug fixes Connection Names If you downloaded and used version 3.2.1 and noticed some of your connection names were no longer valid due to ‘special’ characters, we’ve loosed our restrictions a bit for 3.2.2. You can now go back to using spaces and hyphens in your connection names. periods, spaces, hyphens should now all work More Copy & Paste Stuff While fixing a bug, the developer decided to also enhance the feature while he was in the code. I love seeing this happen organically. No one is sitting over their shoulder with the red magic marker. No, I’m too far away to do that except on very special days So here’s a ‘trick’ – if you want to copy cells from your grids, just drag the selected cells to the worksheet/editor. You’ll get a comma delimited list – very handy! Select cells, drag and drop up to the worksheet – Voila! Comma separated values

  • Formatting Keywords to UPPERCASE In Oracle SQL Developer

    - by thatjeffsmith
    I received this question from a customer today, and it took me more than a few minutes to remember where this preference was located in SQL Developer. This tells me that the topic is ripe for blogging How do I go FROM: select * from scott.emp where ename like '%JEFF%' TO SELECT * FROM scott.emp WHERE ename LIKE '%JEFF%' It’s all in the formatting You need to access the formatting preferences under the Tools menu. It takes a bit of navigating to get there, so bear with me: Tools Database SQL Formatter Oracle Formatting Click ‘Edit’ on the profile Other Case change: ‘Keywords Uppercase’ It’s easy to find once you know where to look? You can tell it to leave the case alone, upper everything, upper only the keywords, lower everything. Accessing the Formatter Options We allow separate formatting options for different RDBMS. You need to make sure you’re accessing the ‘Oracle Formatting’ page in the preferences. You can then choose to edit the default options OR you can do what I have done – save the defaults as a new set of options. I’ve called my profile ‘JeffCustom.’ I can now switch back and forth now through different sets of formatting options. You need to hit the ‘Edit’ button to get to the formatting options editor. A good number of people seem to miss this. Select your profile, then hit the ‘Edit’ button

  • SQL Developer: Describe versus Ctrl+Click to Open Database Objects

    - by thatjeffsmith
    In yesterday’s post I talked about you could use SQL Developer’s Describe (SHIFT+F4) to open a PL/SQL Package at your cursor. You might get an error if you try to describe this… If you actually try to describe the package as you see it in the above screenshot, you’ll get an error: Doh! I neglected to say in yesterday’s post that I was highlighting the package name before I hit SHIFT+F4. This works just fine, but it will work even better in our next release as we’ve fixed this issue. Until then, you can also try the Ctrl+Hover with your mouse. For PL/SQL calls you can open the source immediately based on what you’re hovering over with your mouse cursor. You could try this with “dbms_output.put_line(” too Ctrl+Click, It’s not just for PL/SQL If you don’t like the floating describe windows you get when you do a SHIFT+F4 on a database object, the ctrl+click will work too. Instead of opening a normal ‘hover’ panel, you’ll be taken directly to the object editor for that table, view, etc. Go ahead and try it right now. Paste this into your worksheet, then ctrl+click with your mouse over the table name: select * from scott.emp And now you know, the rest of the story.

  • SQL Developer Debugging, Watches, Smart Data, & Data

    - by thatjeffsmith
    After presenting the SQL Developer PL/SQL debugger for about an hour yesterday at KScope12 in San Antonio, my boss came up and asked, “Now, would you really want to know what the Smart Data panel does?” Apparently I had ‘made up’ my own story about what that panel’s intent is based on my experience with it. Not good Jeff, not good. It was a very small point of my presentation, but I probably should have read the docs. The Smart Data tab displays information about variables, using your Debugger: Smart Data preferences. You can also specify these preferences by right-clicking in the Smart Data window and selecting Preferences. Debugger Smart Data Preferences, control number of variables to display The Smart Data panel auto-inspects the last X accessed variables. So if you have a program with 26 variables, instead of showing you all 26, it will just show you the last two variables that were referenced in your program. If you were to click on the ‘Data’ debug panel, you’ll see EVERYTHING. And if you only want to see a very specific set of values, then you should use Watches. The Smart Data Panel As I step through the code, the variables being tracked change as they are referenced. Only the most recent ones display. This is controlled by the ‘Maximum Locations to Remember’ preference. Step through the code, see the latest variables accessed The Data Panel All variables are displayed. Might be information overload on large PL/SQL programs where you have many dozens or even hundreds of variables to track. Shows everything all the time Watches Watches are added manually and only show what you ask for. Data on Demand – add a watch to track a specific variable Remember, you can interact with your data If you want to do more than just watch, you can mouse-right on a data element, and change the value of the variable as the program is running. This is one of the primary benefits to debugging over using DBMS_OUTPUT to track what’s happening in your program. Change the values while the program is running to test your ‘What if?’ scenarios

    Introducing the Developer Dashboard As a SharePoint developer (or IT Professional), how many times have you had the pleasure of figuring out why a particular page on your site is taking too long to render? I'm sure one of the techniques you have employed in troubleshooting is the process of elimination - removing individual web parts from the page hoping to identify which web part is misbehaving. One of the new features of SharePoint 2010 is the Developer Dashboard. This dashboard provides tracing and performance information that can be useful when you are trying to troubleshoot pages that are loading too slow. The Developer Dashboard is turned off by default and I'll go over 3 different ways to display it. Here is a screenshot of what the Developer Dashboard looks like when displayed at the bottom of the page:   You can see on the left side the different events that fired during the page processing pipeline and how long these events took. This is where you will see individual web parts being processed and how long it took to complete (obviously the kind of processing depends on what the web part does). On the right side you would see the different database calls issued through the SharePoint Object Model to process the page. You will notice that each of these database queries are actually a hyperlink and clicking on it displays a pop-up window that shows the actual SQL Query Text, the Call Stack that triggered the database call, and the IO statistics of that query. Enabling the Developer Dashboard Option 1: Managed Code   The Developer Dashboard is a farm-wide setting and the code above won't work if it is used within a web part hosted on any non-Central Admin site. The SPDeveloperDashboardLevel enum has three possible values: On, Off, and OnDemand. Setting it to On will always display the Developer Dashboard at the bottom of the page. Setting it Off will hide the Developer Dashboard. Setting it to OnDemand will add an icon at the top right corner of the page (see screenshot below) where a Site Collection Admin can toggle the display of the Developer Dashboard for a particular site collection. In my opinion, OnDemand is the best setting when troubleshooting a page or during development since a Site Collection Admin can turn it on or off and for a particular site only. The first cool thing about this is that the Site Collection Admin that turned it on will be the only one to see the Developer Dashboard output. Everyday users won't see the Developer Dashboard output even if it was turned on by a Site Collection Admin. If you need more flexibility on who gets to see the Developer Dashboard output, you can set the SPDeveloperDashboardSettings.RequiredPermissions to control which group of users will have the permission to see the output. Option 2: Using stsadm Using stsadm, you can run the following command to configure the Developer Dashboard: STSADM –o setproperty –pn developer-dashboard –pv OnDemand To successfully execute this command, be sure you that are running as a Farm Admin. Option 3: Using PowerShell For all scripts in SharePoint 2010, I prefer writing them as PowerShell scripts. Though the stsadm command is less verbose, the PowerShell equivalent is pretty straightforward and uses the SharePoint Object Model: You can of course parameterized the value that gets assigned to the DisplayLevel property so you can turn it On, Off or OnDemand depending on the parameter. Events and the Developer Dashboard  Now, don't assume that all the code inside your web part or page will show up in the Developer Dashboard complete with all the great troubleshooting information. Only a finite set of events are monitored by default (for a web part it will events in the base web part class). Let's say you have a click event that could take some time, for example a web service call. And you want to include troubleshooting information for this event in the Developer Dashboard. Enter SPMonitoredScope which is also a new feature in SharePoint 2010. In SharePoint 2010, everything is executed within a "Monitored Scope". And each scope has a set of "Monitors" that measures and counts calls and timings which appears in the Developer Dashboard. Below is an example on how to get your custom code to get included in the Developer Dashboard by wrapping it inside a new monitored scope: The code above would include your new scope "My long web service call" into the Developer Dashboard and would log the time it took to complete processing. In my opinion, wrapping your custom code in a SPMonitoredScope is a SharePoint development best practice since it provides you visibility and a better understanding on the performance of your components.
