• Can't connect to server from certain machines

  - by Joel Coel

  On a small college campus we have a VLAN setup for the computer labs. These machines get assigned IP addresses in the 192.168.7.xxx range. In the server room, all of the server are on the default VLAN and assigned an IP address in the 10.1.1.xxx range. For the most part this works, but the lab machines are unable to connect to one of the servers. They can't even ping it. They can talk to other servers on the same switch as this server just fine. At first I thought it might be a vlan issue, but I changed the server port vlan to match other known-working ports with no effect. Any ideas?

• Redirect channel to another speaker

  - by stex

  Hi, I'm not sure about the title but don't know how to say it in a clearer way. My Soundcard is a Creative X-Fi and I'm using the Creative console starter. Now I'd like to use my speakers not only for my normal screens but also when using a beamer. Due to my room's geometry, the only place for the beamer's projection is a wall which is right to my normal screens (so the projection would be between the front right and the rear right speaker). Now I'm thinking about redirecting the channels to the correct speakers somehow. As far as I remember, in previous version of creative console starter there was an option to do this (e.g. redirect front left to rear right output channel). Does anyone know how to do this with software? Of course I could install a cable switch, but if there's a way without I'd prefer this :) Thanks in advance.

  - by Chris

• What will Time Machine do when

  - by Joel Budgor

  When Time Machine says "I will delete the oldest files first" does it mean this literally. Here is a theoretical example. Source Drive: 300 GB, consisting of 1 280 GB file and a 1 GB file. Backup Drive: 300 GB The initial backup will backup both files, using 281 GB. If I modify the 1 GB file 21 times, what will Time machine do when I run out of room on the backup drive; Delete the original 280 GB because it is the oldest file or delete the oldest version of the file I have modified 21 times. I hope it would delete the oldest version of the file I have modified 21 times, but I want to be sure. Thanks, Joel Budgor

• How to convert WinXP + Apps on RAID0 to use just one of the two RAID disks?

  - by chris5gd

  I have two 150GB SATA drives in hardware RAID 0, on which I have my C: (Win XP) and D: (installed apps). I'm migrating to Windows 7, but I want to keep my XP system until I've got it all running smoothly. So I want to: break the RAID move C: and D: to one of the drives (there's enough room) use the other drive for Win 7 boot into one or the other Clearly I can't move C: and D: after breaking the RAID, so I'm assuming I need to image the two partitions first, then break the RAID and restore the images to one of the drives. So my questions are: Is this possible? If so, what would be a good (free) imaging/restore tool? How do I ensure that the drive will boot after restoring the images? What sort of gotchas should I look out for? If there's a better solution than this, I'd be grateful for suggestions. Thanks!

• How to reduce the windows network browsing broadcast timeout or disable this function?

  - by Moi42

  Hello everyone. My residential network is make of 300 vlans (one per room). To browse them we are using a wins server. My problem is that when I try to browse the network, windows first tries to find the neighborhood using some broadcast, and only then does it query the wins server. This "broadcast period" lasts exactly 30 seconds and is very annoying. Can I reduce it, or can I completely disable this broadcast network discovery feature from my system? Thank you for your answers.

• How do I set up a proxy server for home with bandwidth control, download limit options?

  - by Quakeboy

  3 room mates share a single 2 Mbps connection. Have a 40GB per month download limit beyond which speed drops to 256Kbps which is annoying. One of the roommates abuses the connection by downloading beyond his quota limit. I have a Netgear WNR1000v2 Wireless router + ADSL Modem to connect to the internet. We all access internet via Wireless router which connects to ADSL Modem. I need a free proxy solution which can help me set 40GB / 3 (13 GB) limit for each person (every person has 2 devices - a PC and a phone with Wifi) Uniform Bandwidth control - when 2 people browse the internet they should get 1 Mbps each, and when 3 people access, they should get 2Mbps divided by 3. After each person crosses their monthly download limit, they should be able to access the internet with 256Kbps speed only or lesser. Can I have a custom firmware on my wireless router do this (or) Do I need a proxy server ? Please point me to any relevant tutorials (for example with Squid).

• Synced audio ouput on multiple machines? VLC? hardware solutions?

  - by zimmer62

  I'm wondering if there is any software or hardware solutions to synced audio or audio and video across multiple computers or devices on a network. I've seen Sonos, and it might be a good solution, but it's also a very expensive solution. I'd like to be able to play something with realtime audio output on one PC, but hear it on speakers throughout the house, being it the home theater receiver, or another computer in another room. I saw a solution using the apple iport express, but the latency was unacceptable for anything other than just music. I'd like to avoid running audio wires with baluns to a bunch of amplifiers scattered all over the place when I have cat5 run everywhere. Is anyone familiar with using this kind of process for whole home audio? The latency is a big deal for me, if I've got video attached to the sound (e.g. watching a hockey game)

• Moving an "all-in-one" PC when turned on/off

  - by Purak

  I have an "all-in-one" pc. I know that moving a pc when it is switched on is harmful to the hardware components. What I would like to know is if the same applies to "all-in-one" pc's and if the same applies to regularly moving it from one side of the room to the other when it is turned off! The reason for the question is that I work on one desk during the day, and in the evening move it to the couch so I can do other stuff while watching TV or something. I always turn it off before the move, but somebody told me that I can be damaging the machine by doing so. Can anybody shed some light on this? Many thanks

• Resize windows command line prompt?

  - by Yuval

  I'm working on a Windows xp machine. I wrote a program in assembly that outputs some text, and am trying to create a screenshot of the command line output (start-run-"cmd"). The problem is that the text initially printed by the program gets pushed up by later text and I cannot scroll to it. I tried playing around with the width and height under properties = layout but it seems to resize the window itself (the borders) without resizing the textarea inside the window (text does not have more "room", but the window is bigger). Does anybody know a workaround/solution for this? Thank you!

• Is it normal for the laptop charger to spark when plugging in?

  - by Cd-MaN

  All the laptop chargers I had until now sparked whever I plugged them in. This is true for my old charger (the bulkier / rounder Dell model) and the new charger (the flat Dell model) with two different Dell laptops, however until recently I didn't give it much thought. Then, in the last couple of months: I shorted out a conference room and melted the floor a little (the wire caught fire) The second charger (also a Dell original) died, taking the power strip with it I'm wondering: Is it normal for laptop chargers to spark when plugged in? Specifically new, original Dell chargers Is there a "correct" way to plug / unplug chargers? Do I need to first unplug it from the wall and then from the laptop / do I need to first plug it into the wall and then into the laptop? May the problem be caused by the fact that I leave sometimes the charger plugged into the wall without connecting the laptop for longer periods of time (up to a day)? PS. I'm talking about Europe, so 220V and this happens in many places (at home, at my parents, at work, in hotels I trave to, etc)

• Powering off sends me to "Launch Windows Repair" automatically instead! What do I do?

  - by Jason

  With Windows 2008 R2 Server, I noticed that if I remotely reboot the machine (because it is hung or I think it is hung), the server, when it restarts, defaults to "Launch Windows Repair" (or something similar) rather than "Start Windows Normally". To change it, I have to trek down to the server room and change the boot up otherwise it will go into an endless loop (because I don't have the setup media and DVD-ROM installed). This seems to be new with 2008 R2 because I have not seen it elsewhere. What do I do? How can I remove this or change the default?

• Some explaination on WLAN adaptor antennas and radios

  - by gert_78

  We have a desktop in a room where the is no wired connection that has bad reception from the wireless AP. Someone (I don't remember who of course) told me there are high gain antennas that will make it possible to get a better reception (and throughput). I believe he said they are adaptors with "high gain" antennas. He also told me he uses it in hotels when he has a bad WLAN reception. When he connects that card the reception and speed is a lot better all of a sudden. But can someone explain me in understandable language what that is and what the thing with high gain, dB, dBi and mW is all about please? What type of card do we need? On like this or this?

• 1 tera flop cluster?

  - by Adobe

  I want to buy a $40000 1 tera flop cluster to keep it in a room. What are the standard configurations? Cluster is supposed to do molecular dynamics simulations on biological systems. I'm proposed a 4 pc with 8 cores each by the selling company I'm deadling with. It looks like I also need infiniband. Does some one has an experience -- what phisical memory should I buy etc? I know things change very quickly... Still there might be a point or two to state. Edit: Custer is supposed to run linux, and gromacs in it.

• CentOS I/O blocking flushing dirtypages

  - by user3662224

  I have an Apache webserver on CentOS. It is not doing anything fantastic or complicated at all but it does at intervals experience a high load (120 for 4 CPUs) for some reason. During this time I see high waits and write durations. I have narrowed this down to flushing of dirtypages to disk to make room for new data. I have tried many things and talked to the developers who are also puzzled by this. I am stumped. Details: vmware virtual guest server 4 cpus 12G RAM Apache PHP I have 40 servers in this cluster that share the same disk structure. Only the webservers are experiencing this issue. Any ideas?

• Code that Worked with MultiView fails with Wizard ASP.NET

  - by davemackey

  I originally created a process that occurred by transitioning between views in a multiview and it worked fine. Now, I've moved this same code into a ASP.NET Wizard and it keeps throwing an error at the second step. The error is: Method 'System.Object AndObject(System.Object, System.Object)' has no supported translation to SQL. Any ideas why this would occur when moving the code into the wizard? I'm sure its something stupid, but I've checked over the code 3-4 times now and it appears identical operationally.

• Rearrange array

  - by bradenkeith

  Array starts like this: Array ( [SMART Board] => Array ( [0] => sb1 [1] => sb2 [2] => sb3 ) [Projector] => Array ( [0] => pr1 [1] => pr2 [2] => pr3 ) [Speakers] => Array ( [0] => sp1 [1] => sp2 [2] => sp3 ) [Splitter] => Array ( [0] => spl1 [1] => spl2 [2] => spl3 ) [Wireless Slate] => Array ( [0] => ws1 [1] => ws2 [2] => ws3 ) ) The keys are used as my table columns titles. Their individual arrays are to carry the column information. I have split it up even further with array_slice and array_merge_recursive to look pretty as 2 arrays - 1 holds the column names, the other looks like this: Array ( [0] => sb1 [1] => sb2 [2] => sb3 [3] => pr1 [4] => pr2 [5] => pr3 [6] => sp1 [7] => sp2 [8] => sp3 [9] => spl1 [10] => spl2 [11] => spl3 [12] => ws1 [13] => ws2 [14] => ws3 ) However, when trying to write the table I'm getting keys 0, 1, 2 as the column data, then row break then 3, 4, 5 then row break... etc. I need it to be 0, 3, 6, 9, 12 row break 1, 4, 7, 10, 13 row break etc... How can I either rearrange my array to allow for this, or rewrite how the data goes into the table so that the correct information lines up with the appropriate column? foreach(unserialize($dl->data) as $data){ //first 3 are specialinstructions, system, and room $uniques = array_slice($data,0,3); $rows = array_slice($data,3); $rows2 = array_merge_recursive($rows2, $rows); //get the specialinstructions, system, and room foreach($uniques as $unique){ echo $unique."<br/>"; }///foreach uniques echo "<br>"; }///foreach unserialized $numberofrooms = count($rows2[key($rows2)]); $numberofproducts = count($rows2); print_r($rows2); unset($rows); //write the individual rows foreach($rows2 as $header=>$rowset){ $headers[] = $header; foreach($rowset as $row){ $rows[] = $row; }//foreach rowset }//foreach rows2 echo "<p>"; print_r($rows); echo '<table class="data-table"> <caption>DL</caption> <thead><tr>'; foreach($headers as $header){ echo "<th>".$header."</th>"; } echo '</tr></thead>'; echo '<tbody>'; $i = 0; foreach($rows as $row){ if($i == 3 || $i == 0){ echo "<tr>"; $i = 1; } echo '<td>'.$row.'</td>'; if($i == 2){ echo "</tr>"; } $i++; } echo '</tbody></table>';

• "Too much recursion" error when loading the same page with a hash

  - by Elliott

  Hi, I have a site w/ an image gallery ("Portfolio") page. There is drop-down navigation that allows a user to view a specific image in the portfolio from any page on the site. The links in the navigation use a hash, and that hash is read and converted into a string of an image filename. The image src attribute on the /portfolio/ page is then swapped out with the new image filename. This works fine if I'm clicking the dropdown link from a page OTHER THAN the /portfolio/ page itself. However if I take the same action from the /portfolio/ page, I get a "too much recursion" error in Firefox. Here's the code: Snippet of the nav markup: <li>Portfolio Category A <ul> <li><a href="/portfolio/#dining-room-table">Dining Room Table</a></li> <li><a href="/portfolio/#bathroom-mirror">Bathroom Mirror</a></li> </ul> </li> JS that reads the hash, converts it to an image filename, and swaps out the image on the page: $(document).ready(function() { if(location.pathname.indexOf("/portfolio/") > -1) { var hash = location.hash; var new_image = hash.replace("#", "")+".jpg"; swapImage(new_image); } }); function swapImage(new_image) { setTimeout(function() { $("img#current-image").attr("src", "/images/portfolio/work/"+new_image); }, 100); } I'm using the setTimeout function because I'm fading out the old image before making the swap, then fading it back in. I initially thought this was the function that was causing the recursion error, but when I remove the setTimeout I still have this problem. Does this have to do with a closure I'm not aware of? I'm pretty green on closures. JS that listens for the click on the nav: $("nav.main li.dropdown li ul li").click(function() { $(this).find("a").click(); $("nav.main").find("ul ul").hide(); $("nav.main li.hover").removeClass("hover"); }); I haven't implemented the fade in/out functionality for the dropdown nav yet, but I have implemented it for Next and Previous arrows, which can also be used to swap out images using the same swapImage function. Here's that code: $("#scroll-arrows a").click(function() { $("#current-image").animate({ opacity: 0 }, 100); var current_image = $("#current-image").attr("src").split("/").pop(); var new_image; var positions = getPositions(current_image); if($(this).is(".right")) { new_image = positions.next_img; } else { new_image = positions.prev_img; } swapImage(new_image); $("#current-image").animate({ opacity: 1 }, 100); return false; }); Here's the error I'm getting in Firefox: too much recursion var ret = handleObj.handler.apply( this, arguments ); jquery.js (line 1936) Thanks for any advice.

• SQL SERVER – SHRINKFILE and TRUNCATE Log File in SQL Server 2008

  - by pinaldave

  Note: Please read the complete post before taking any actions. This blog post would discuss SHRINKFILE and TRUNCATE Log File. The script mentioned in the email received from reader contains the following questionable code: “Hi Pinal, If you could remember, I and my manager met you at TechEd in Bangalore. We just upgraded to SQL Server 2008. One of our jobs failed as it was using the following code. The error was: Msg 155, Level 15, State 1, Line 1 ‘TRUNCATE_ONLY’ is not a recognized BACKUP option. The code was: DBCC SHRINKFILE(TestDBLog, 1) BACKUP LOG TestDB WITH TRUNCATE_ONLY DBCC SHRINKFILE(TestDBLog, 1) GO I have modified that code to subsequent code and it works fine. But, are there other suggestions you have at the moment? USE [master] GO ALTER DATABASE [TestDb] SET RECOVERY SIMPLE WITH NO_WAIT DBCC SHRINKFILE(TestDbLog, 1) ALTER DATABASE [TestDb] SET RECOVERY FULL WITH NO_WAIT GO Configuration of our server and system is as follows: [Removed not relevant data]“ An email like this that suddenly pops out in early morning is alarming email. Because I am a dead, busy mind, so I had only one min to reply. I wrote down quickly the following note. (As I said, it was a single-minute email so it is not completely accurate). Here is that quick email shared with all of you. “Hi Mr. DBA [removed the name] Thanks for your email. I suggest you stop this practice. There are many issues included here, but I would list two major issues: 1) From the setting database to simple recovery, shrinking the file and once again setting in full recovery, you are in fact losing your valuable log data and will be not able to restore point in time. Not only that, you will also not able to use subsequent log files. 2) Shrinking file or database adds fragmentation. There are a lot of things you can do. First, start taking proper log backup using following command instead of truncating them and losing them frequently. BACKUP LOG [TestDb] TO  DISK = N'C:\Backup\TestDb.bak' GO Remove the code of SHRINKING the file. If you are taking proper log backups, your log file usually (again usually, special cases are excluded) do not grow very big. There are so many things to add here, but you can call me on my [phone number]. Before you call me, I suggest for accuracy you read Paul Randel‘s two posts here and here and Brent Ozar‘s Post here. Kind Regards, Pinal Dave” I guess this post is very much clear to you. Please leave your comments here. As mentioned, this is a very huge subject; I have just touched a tip of the ice-berg and have tried to point to authentic knowledge.

• A basic T4 template for generating Model Metadata in ASP.NET MVC2

  - by rajbk

  I have been learning about T4 templates recently by looking at the awesome ADO.NET POCO entity generator. By using the POCO entity generator template as a base, I created a T4 template which generates metadata classes for a given Entity Data Model. This speeds coding by reducing the amount of typing required when creating view specific model and its metadata. To use this template, Download the template provided at the bottom. Set two values in the template file. The first one should point to the EDM you wish to generate metadata for. The second is used to suffix the namespace and classes that get generated. string inputFile = @"Northwind.edmx"; string suffix = "AutoMetadata"; Add the template to your MVC 2 Visual Studio 2010 project. Once you add it, a number of classes will get added to your project based on the number of entities you have.    One of these classes is shown below. Note that the DisplayName, Required and StringLength attributes have been added by the t4 template. //------------------------------------------------------------------------------ // <auto-generated> // This code was generated from a template. // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------   using System; using System.ComponentModel; using System.ComponentModel.DataAnnotations;   namespace NorthwindSales.ModelsAutoMetadata { public partial class CustomerAutoMetadata { [DisplayName("Customer ID")] [Required] [StringLength(5)] public string CustomerID { get; set; } [DisplayName("Company Name")] [Required] [StringLength(40)] public string CompanyName { get; set; } [DisplayName("Contact Name")] [StringLength(30)] public string ContactName { get; set; } [DisplayName("Contact Title")] [StringLength(30)] public string ContactTitle { get; set; } [DisplayName("Address")] [StringLength(60)] public string Address { get; set; } [DisplayName("City")] [StringLength(15)] public string City { get; set; } [DisplayName("Region")] [StringLength(15)] public string Region { get; set; } [DisplayName("Postal Code")] [StringLength(10)] public string PostalCode { get; set; } [DisplayName("Country")] [StringLength(15)] public string Country { get; set; } [DisplayName("Phone")] [StringLength(24)] public string Phone { get; set; } [DisplayName("Fax")] [StringLength(24)] public string Fax { get; set; } } } The gen’d class can be used from your project by creating a partial class with the entity name and setting the MetadataType attribute.namespace MyProject.Models{ [MetadataType(typeof(CustomerAutoMetadata))] public partial class Customer { }} You can also copy the code in the metadata class generated and create your own ViewModel class. Note that the template is super basic  and does not take into account complex properties. I have tested it with the Northwind database. This is a work in progress. Feel free to modify the template to suite your requirements. Standard disclaimer follows: Use At Your Own Risk, Works on my machine running VS 2010 RTM/ASP.NET MVC 2 AutoMetaData.zip Mr. Incredible: Of course I have a secret identity. I don't know a single superhero who doesn't. Who wants the pressure of being super all the time?

• SQL SERVER – A Successful Performance Tuning Seminar – Hyderabad – Nov 27-28, 2010 – Next Pune

  - by pinaldave

  My recent SQL Server Performance Tuning Seminar in Colombo was oversubscribed with total of 35 attendees. You can read the details over here SQLAuthority News – SQL Server Performance Optimizations Seminar – Grand Success – Colombo, Sri Lanka – Oct 4 – 5, 2010. I had recently completed another seminar in Hyderabad which was again blazing success. We had 25 attendees to the seminar and had wonderful time together. There is one thing very different between usual class room training and this seminar series. In this seminar series we go 100% demo oriented and real world scenario deep down. We do not talk usual theory talk-talk. The goal of this seminar to give anybody who attends a jump start and deep dive on the performance tuning subject. I will share many different examples and scenarios from my years of experience of performance tuning. The beginning of the second day is always interesting as I take attendees the server as example of the talk, and together we will attempt to identify the bottleneck and see if we can resolve the same. So far I have got excellent feedback on this unique session, where we pick database of the attendees and address the issues. I plan to do the same again in next sessions. The next Seminar is in Pune.I am very excited for the same. Date and Time: December 4-5, 2010. 10 AM to 6 PM The Pride Hotel 05, University Road, Shivaji Nagar, Pune – 411 005 Tel: 020 255 34567 Click here for the agenda of the seminar. Instead of writing more details, I will let the photos do the talk for latest Hyderabad Seminar.

  - by rituchhibber

       ORACLE FOCUS Oracle PartnerNetwork Exchange@ ORACLE OpenWorld Sylvie MichouSenior DirectorPartner Marketing & Communications and Strategic Programs RESOURCES -- Oracle OpenWorld 2012 Oracle PartnerNetwork Exchange @ OpenWorld Oracle PartnerNetwork Exchange @ OpenWorld Registration Oracle PartnerNetwork Exchange SpecializationTest Fest Oracle OpenWorld Schedule Builder Oracle OpenWorld Promotional Toolkit for Partners Oracle Partner Events Oracle Partner Webcasts Oracle EMEA Partner News SUBSCRIBE FEEDBACK PREVIOUS ISSUES If you are attending our forthcoming Oracle OpenWorld 2012 conference in San Francisco from 30 September to 4 October, you will discover a new dedicated programme of keynotes and sessions tailored especially for you, our valued partners. Oracle PartnerNetwork Exchange @ OpenWorld has been created to enhance the opportunities for you to learn from and network with Oracle executives and experts. The programme also provides more informal opportunities than ever throughout the week to meet up with the people who are most important to your business: customers, prospects, colleagues and the Oracle EMEA Alliances & Channels management team. Oracle remains fully focused on building the industry's most admired partner ecosystem—which today spans over 25,000 partners. This new OPN Exchange programme offers an exciting change of pace for partners throughout the conference. Now it will be possible to enjoy a fully-integrated, partner-dedicated session schedule throughout the week, as well as key social events such as the Sunday night Welcome Reception, networking lunches from Monday to Thursday at the Howard Street Tent, and a fantastic closing event on the last Thursday afternoon. In addition to the regular Oracle OpenWorld conference schedule, if you have registered for the Oracle PartnerNetwork Exchange @ OpenWorld programme, you will be invited to attend a much anticipated global partner keynote presentation, plus more than 40 conference sessions aimed squarely at what's most important to you, as partners. Prominent topics for discussion will include: Oracle technologies and roadmaps and how they fit with partners' business plans; business development; regional distinctions in business practices; and much more. Each session will provide plenty of food for thought ahead of the numerous networking opportunities throughout the week, encouraging the knowledge exchange with Oracle executives, customers, prospects, and colleagues that will make this conference of even greater value for you. At Oracle we always work closely with our partners to deliver solution offerings that improve business value, simplify the IT experience and drive innovation and efficiencies for joint customers. The most important element of our new OPN Exchange is content that helps you get more from technology investments, more from your peer-to-peer connections, and more from your interactions with customers. To this end we've created some partner-specific tools which can be used by OPN members ahead of the conference itself. Crucially, a comprehensive Content Catalog already lists and organises details of every OPN Exchange session, speaker, exhibitor, demonstration and related materials. This Content Catalog can be used by all our partners to identify interesting content that you can add to your own personalised Oracle OpenWorld Schedule Builder, allowing more effective planning and pre-enrolment for vital sessions. There are numerous highlights that you will definitely want to include in those personal schedules. On Sunday morning, 30 September we will start the week with partner dedicated OPN Exchange sessions, following our Global Partner Keynote at 13:00 with Judson Althoff, SVP, Worldwide Alliances & Channels and Embedded Sales and senior executives, giving insight into Oracle's partner vision, strategy, and resources—all designed to help build and strengthen market opportunities for you. This will be followed by a number of OPN Exchange general sessions, the Oracle OpenWorld Opening Keynote with Larry Ellison, CEO, Oracle and concluded with the OPN Exchange AfterDark Welcome Reception, starting at 19:30 at the Metreon. From Monday 1 to Thursday 4 October, you can attend the OPN Exchange sessions that are most relevant to your business today and over the coming year. Oracle's top product and sales leaders will be on hand to discuss Oracle's strategic direction in 40+ targeted and in-depth sessions focussing on critical success factors to develop your business. Oracle's dedication to innovation, specialization, enablement and engineering provides Oracle partners with a huge opportunity to create new services and solutions, differentiate themselves and deliver extreme value to joint customers across the globe. Oracle will even be helping over 1000 partners to earn OPN Specialization certification during the Oracle OpenWorld OPN Exchange Test Fest, which will be providing all the study materials and exams required to drive Specialization for free at the conference. You simply need to check the list of current certification tracks available, and make sure you pre-register to reserve a seat in one of the ten sessions being offered free to OPN Exchange registered attendees. And finally, let's not forget those all-important networking opportunities, which can so often provide partners with valuable long-term alliances as well as exciting new business leads. The Oracle PartnerNetwork Lounge, located at Moscone South, exhibition hall, room 100 is the place where partners can meet formally or informally with colleagues, customers, prospects, and other industry professionals. OPN Specialized partners with OPN Exchange passes can also visit the OPN Video Blogging room to record and share ideas, and at the OPN Information Station you will find consultants available to answer your questions. "For the first time ever we will have a full partner conference within OpenWorld. OPN Exchange @ OpenWorld will kick-off on the first Sunday and run the entire week. We'll have over 40 sessions throughout that time and partners will hear from our top development executives, with special sessions dedicated to partnering throughout.
