• Very uneven CPU utilization with SQL Server 2012 on 2 processor computer with 16 cores / processor

  - by cooplarsh

  After installing SQL Server Enterprise 2012 with the Server + Cal license model, on a computer with 2 processors each with 16 cores (and no hyperthreading involved) and putting the server under extremely heavy load the 16 cores on the first processor were very underutilized, the first 4 cores on the 2nd CPU were heavily utilized, and the last 12 cores were not used at all (because of the 20 core limit for this sql server version). Total CPU utilization was displaying as around 25%. Unfortunately, the server suffered from extremely poor performance even though if the tasks were evenly distributed across the 20 cores it wouldn't have been anywhere near as bad. The Windows Server was running on a VMWare virtual image under ESX Server, but all of the CPU was allocated to the windows server. We tried changing affinity settings (e.g., allocating most cores to CPU and the others to I/O), but that didn't help solve the performance problems. Upgrading the product edition to SQL Server Enterprise Core 2012 not only allowed the SQL Server to utilize the 12 previously unused cores on the 2nd processor, but it also resulted in a much more even distribution of tasks across all of the processors. To get through the backlog of requests cpU utilization jumped to around 90%, and then came down to around 33% once it was caught up, but performance improved dramatically since we failed over to the newly updated version And the performance issues went away. I was wondering if anyone knows what might cause SQL Server to unevenly distribute the load, relying almost exclusively on the first 4 cores of the 2nd processor that had 12 cores idle, and allocate only a few tasks to each of the 16 cores on the first processor. Also, is there any way we could have more evenly distributed the load across the 20 cores that were being used without the product edition upgrade? The flip side of that question is what did the product upgrade do that caused SQL Server to start evenly distributing the load across all of the cores that it recognized? Thanks to any insight to answer these questions and/or links that might help me better understand how to make sense of what was happenings.

• Java web app deployment and ControlTier adoption

  - by Ran

  I've been searching for a configuration and deployment manager tool for my java-linux based web service and have been looking mainly at ControlTier (http://controltier.org). We operate at a medium scale (100's of hosts, multi-DC, dozens of services). There seem to be be plenty of lower level system admin tools such as chef, puppet, cfengine, bcfg2 and more and my understanding and the reason I'm calling them "low level" is that they are great for system level administration tasks such as setting up a mount, file permissions, users etc but aren't designed, for example for java deployments, which usually come with a build process and special java semantics. In many cases any tool can be used to do anything but if it was not designed for the task it can get uncomfortable. OTOH control-tier seem to have been designed just for that - java application deployments, at least that's what all the tutorials on their site demonstrate but here's the problem - The wiki at http://controltier.org/wiki/ is pretty good and stuffed with examples and the company behind the open source CT product is very responsive (pushy...) however, I'm yet to have seen any material from 3rd party users on the net. No success stories, no detailed blog posts, no best practices, no cheat sheets, not even hate letters, nothing. This plays badly for DTO solutions, CT's sponsor for two reasons, one is that it makes me suspicious what's the reason for the poor adoption? and second, what do I do if I get stuck and there's no help page on CT's wiki page and the mailing list is too slow to answer. I'm stuck with a "free" product that a consultancy company is pushing. So my question here - I'd be interested in hearing if anyone has had real world experience with CT for java based web app deployments and if he'd thumb up the product? Any other comments that may enlighten me are welcome of course...

• Question About mk-table-checksum Results

  - by stevenmusumeche

  Hello, I have 1 master and 2 slaves. I am using MySQL 5.1.42 on all servers. I am attempting to use mk-table-checksum to verify that their data is in sync, but I am getting unexpected results on one of the slaves. First, I generate the checksums on the master like this: mk-table-checksum h=localhost --databases MYDB --tables {$table_list} --replicate=MYDB.mk_checksum --chunk-size=10M My understanding is that this runs the checksum queries on the master which then propagate via normal replication to the slaves. So, no locking is needed because the slaves will be at the same logical point in time when they run the checksum queries on themselves. Is this correct? Next, to verify that the checksums match, I run this on the master: mk-table-checksum --databases MYDB --replicate=IRC.mk_checksum --replicate-check 1 h=localhost,u=maatkit,p=xxxx If there are any differences, I repair the slaves like this: mk-table-sync --execute --verbose --replicate IRC.mk_checksum h=localhost,u=maatkit,p=xxxx After doing all of this, I repaired both slaves with mk-table-sync. However, everytime I run this sequence (after everything has already been repaired), one slave is perfectly in sync but one slave always has a few tables out of sync. I am 99.999% sure that the data on the slaves matches, since I repaired everything and the tables were not even updated on the master between runs of the checksum script. What would cause a few tables to always show out of sync on only one of the slaves? I am stuck. Here is the output: Differences on h=x.x.x.x,p=...,u=maatkit DB TBL CHUNK CNT_DIFF CRC_DIFF BOUNDARIES IRC product 10 0 1 product_id = 147377 AND product_id < 162085 IRC post_order_survey 0 0 1 1=1 IRC mk_heartbeat 0 0 1 1=1 IRC mailing_list 0 0 1 1=1 IRC honey_pot_log 0 0 1 1=1 IRC product 12 0 1 product_id = 176793 AND product_id < 191501 IRC product 18 0 1 product_id = 265041 IRC orders 26 0 1 order_id = 694472 IRC orders_product 6 0 1 op_id = 935375

• RAM being displayed is lesser than the actual in my Windows 7

  I am using Windows 7 and Ubuntu on the same machine. Earlier I had 3 GB of RAM,but now the Windows is displaying just 1 GB of RAM.

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by indyvoyage

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• Restoring Windows 2008 Server X86 and X64

  - by rihatum

  Restoring Windows 2008 Server (Domain Controller) We are using Backup Exec System Recovery 2010 to Image our DC. Now this software has a feature to convert the backup into a vmware or hyper-v VM I have also used disk2vhd to convert one of our dc's to a vhd and when I connected it into Hyper-V, it booted fine, I can login - BUT :-) As soon as I login, I get the activation error, that change product key, this product key isn't good for this machine etc. Question is : When in a real recovery situation, what would be the procedure to restore it either virtual or onto a physical box but be able to login and change product key etc ? In this scenario its just locked down and I cant' do anything, if this is the case, how would I replicate my production environment via these tools ? Any Ideas ? Will be grateful for some real world examples here. Same thing happens with our exchange backup / test restore either physical or virtual, can login but nothing else. Now we don't have the keys as they are OEM keys and just wondering what will happen in a real scenario, would we be purchasing another KEY or using the OEM key on our new server ? This is a test environment I am trying to create by restoring our backups either into hyper-v or physical test machines. Also, If I build up a machine (Server 2008) in a VM (Hyper-V), How can I restore just the system state backup of my DC into it ? will that give me the activation error too ? even though I would use the TRIAL ISOs provided by Microsoft ? Kind regards

• Outlook VBA script - find and replace text with image

  - by user2530616

  I have a e-commerce store. When I get a sale, I receive an order confirmation email which contains the name of the product sold. When the email comes through, I would like to run a script that replaces the product name eg. "red widget", with a picture of that product. Is that possible? I have found a similar code to replace text (set of numbers in this case) with a link, but I need it to replace with a picture instead. Option Explicit Sub InsertHyperLink(MyMail As MailItem) Dim body As String, re As Object, match As Variant body = MyMail.body Set re = CreateObject("vbscript.regexp") re.Pattern = "#[0-9][0-9][0-9][0-9][0-9][0-9]" For Each match In re.Execute(body) body = Replace(body, match.Value, "http://example.com/bug.html?id=" & Right(match.Value, 6), 1, -1, vbTextCompare) Next MyMail.body = body MyMail.Save End Sub example mail Order Confirmation Thanks for shopping with us today! ------------------------------------------------------ Order Number: 2209 Date Ordered: Friday 28 June, 2013 Products ------------------------------------------------------ 1 x red widget = $5.00 ------------------------------------------------------ Total: $0.00 Delivery Address xxx search text: "red widget" replace picture: redwidget.jpg

• Correct MySQL username/password, but getting Access Denied error when run from script

  - by Nick

  I'm currently trying to run the following command from within a shell script. /usr/bin/mysql -u username -ppassword -h localhost database It works perfectly fine when executed manually, and not from within a script. When I try to execute a script that contains that command, I get the following error: ERROR 1045 (28000) at line 3: Access denied for user 'username'@'localhost' (using password: YES) I literally copied and pasted the working command into the script. Why the error? As a sidenote: the ultimate intent is to run the script with cron. EDIT: Here is a stripped down version of my script that I'm trying to run. You can ignore most of it up until the point where it connects to MySQL around line 19. #!/bin/sh #Run download script to download product data cd /home/dir/Scripts/Linux /bin/sh script1.sh #Run import script to import product data to MySQL cd /home/dir/Mysql /bin/sh script2.sh #Download inventory stats spreadsheet and rename it cd /home/dir /usr/bin/wget http://www.url.com/file1.txt mv file1.txt sheet1.csv #Remove existing export spreadsheet rm /tmp/sheet2.csv #Run MySQL queries in "here document" format /usr/bin/mysql -u username -ppassword -h localhost database << EOF --Drop old inventory stats table truncate table table_name1; --Load new inventory stats into table Load data local infile '/home/dir/sheet1.csv' into table table_name1 fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; --MySQL queries to combine product data and inventory stats here --Export combined data in spreadsheet format group by p.value into outfile '/tmp/sheet2.csv' fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; EOF EDIT 2: After some more testing, the issue is with the << EOF that is at the end of the command. This is there for the "here document". When removed, the command works fine. The problem is that I need << EOF there so that the MySQL queries will run.

• Recommended drive encryption solution

  - by Chris Driver

  Hello, I will soon be purchasing a number of laptops running Windows 7 for our mobile staff. Due to the nature of our business I will need drive encryption. Windows BitLocker seems the obvious choice, but it looks like I need to purchase either Windows 7 Enterprise or Ultimate editions to get it. Can anyone offer suggestions on the best course of action: a) Use BitLocker, bite the bullet and pay to upgrade to Enterprise/Ultimate b) Pay for another 3rd party drive encryption product that is cheaper (suggestions appreciated) c) Use a free drive encryption product such as TrueCrypt Ideally I am also interested in 'real world' experience from people who are using drive encryption software and any pitfalls to look out for. Many thanks in advance... UPDATE Decided to go with TrueCrypt for the following reasons: a) The product has a good track record b) I am not managing a large quantity of laptops so integration with Active Directory, Management consoles etc is not a huge benefit c) Although eks did make a good point about Evil Maid (EM) attacks, our data is not that desirable to consider it a major factor d) The cost (free) is a big plus but not the primary motivator The next problem I face is imaging (Acronis/Ghost/..) encrypted drives will not work unless I perform sector-by-sector imaging. That means an 80Gb encrypted partition creates an 80Gb image file :(

• DVI splitter not working as expected/confusion between DVI-D and -I

  - by Freakishly

  Hey guys, thanks for looking. I have an ATI FirePro™ V3700 in my desktop machine, and I have been running a dual-monitor setup quite effortlessly, thanks to the two DVI ports on the card. I came upon a third monitor, and wanted to extend my desktop to 3 screens, so I purchased a DVI splitter from Amazon. Now, I can only duplicate the second monitor onto the third, not extend it. I've tried all possible combinations of input to no avail. Here's the setup: The ATI FirePro™ V3700 has two Dual-Link DVI-I outputs The splitter splits a single Dual-Link DVI-I port into two Dual-Link DVI-I outputs Two of the monitors are NEC E222W, and the third monitor is a Dell 2001FP. Each monitor has one D-Sub and one Dual-Link DVI-D input. Cables going from the video card to the monitors are two Dual-Link DVI-D to the NECs and one Single-Link DVI-D to the Dell. Is the problem likely with the DVI-D/DVI-I mismatch? Or is it with the cable on the Dell that is only a Single-Link? The cables are easily replaceable, the monitors not so much. Thanks for your time, I really appreciate it. http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3700/Pages/v3700-specs.aspx http://www.amazon.com/Cables-Unlimited-DVI-D-Splitter-PCM-2260/product-reviews/B000H09RFM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 www dot newegg dot com/Product/Product.aspx?Item=N82E16824002495 accessories dot us dot dell dot com/sna/PopupProductDetail.aspx?cs=19&l=en&c=us&sku=320-1578 Apologies for the fudged links, I'm new here and they won't let me post more than two :P

• Platform to allow users to suggest and vote for ideas

  - by Simon

  I head up a support team for a software product. I am in the process of setting up a blog (Wordpress.org), a forum (PHPBB or maybe Vanilla), a means to view bugs (probably expose Jira), but would also like to allow our customers to suggest enhancement requests. Currently we have this as a 'contact form' via the blog, which feeds into a dedicated inbox, which the product manager reviews and may include some of these ideas into the product. However, I would like to give the clients more power/visibility over this. Have a look at ideas.arcgis.com. There are plenty of other similar sites as well. Users can suggest new ideas Other users can vote these ideas up or down (similar to Stack Exchange sites) Ideas that are voted highly will be given a higher priority over lower ones. We can report back on the # of ideas we implement, and potentially reject ideas with reasoning. Has anyone seen any platforms (ideally free) which would replicate something similar to this? I was half thinking of embedding Vanilla within a wordpress page, but need to look into it more.

• Euro character messed up during FTP transfer

  - by djechelon

  My customer is using a very outdated ecommerce management system on my hosting service. For that product, no support is being provided anymore by the vendor. Brief explanation: the shop website, that claims to run under LAMP stack, is built by an old Visual Basic Windows application running on MS Access. The user constructs the shop, defines the HTML template, adds products and categories, etc. Then the VB exe builds the PHP pages (one for each template page) and the SQL script to run on MySQL. It also uploads everything via FTP and runs the installation/upgrade script on its own. The problem Browsing the website, many products' descriptions are cut before the euro sign. For example, what was supposed to be "Product price €1000" becomes "Product price" The analysis MySQL contains a cutted description until the € sign, so it's not PHP fault The Access databases contain full description with € sign, so it's not fault of the webmaster writing bad description or eDisplay cutting them The SQL that will run once the site gets uploaded, stored on my local machine before upload, contains the € sign The same script, after being FTPed by eDisplay and opened with nano from SSH, shows the € sign messed up like this: ^À vsftpd log reports (obfuscated for privacy) Sat Dec 15 11:16:57 2012 22 xxx.xxx.128.13 1112727 /srv/www/domains/xxxxxx.it/htdocs/db.sql b _ i r xxxxxxx ftp 0 * c which seems to be a binary transfer (and also a huge security vulnerability because you can download the whole database from unauthenticated HTTP) The eDisplay internal FTP client provides no option for ascii/binary transfer modes [Add] Trying to manually upload the SQL file via SFTP shows messing up euro [Add2] Trying to manually upload using Xftp client with explicit ASCII mode doesn't fix too It looks like the file gets uploaded as binary. Perhaps on the customer's previous host it all worked fine because that was a Windows host. The server It's an Azure virtual machine running openSUSE 12.2 with both vsftpd and openSSH The question Without asking the customer to manually upload files using FileZilla or replacing € with &euro;, because he refuses, what can I do on server side to prevent vsftpd to screw up euro sign?

• Cloned Centos 6.4 websrver for test purpose. Virtual host, .htaccess, redirecting url issue

  - by Shogoot

  I see similar questions, but not my exact challenge. What I have done so far I cloned a prod server over to a vmware to use it as a test server for new functionality I'm going to write. I'm not a sysadmin by trade, but I'm new to this company and I have to do some thing that are outside of my comfort zone (thats a good thing :) ) The prod server has 2 sites on it s1.com and s2.com. In /html/s1/, /html/s2/ there's an .htaccess file under each s*/. Looking like this: RewriteEngine ON RewriteBase / RewriteCond %{QUERY_STRING} id=([0-9]+) RewriteRule ^.* %1.htm RewriteCond %{QUERY_STRING} page=modules/checkout RewriteRule ^.* order.php RewriteCond %{QUERY_STRING} page=pages/sidekart RewriteRule ^.* pages/sidekart.htm The issue is that s1 has a lot of pages that really belongs under a third domain s3, the rule in line 4 and 5 redirects them to /html/s1/. An example of such URL is: s3.com/?page=modules/product&id=521614 I'm trying then to get those URLs (without modifying the URL) to redirect to s3's /html/s3/ server structure, which I set up making a new virtualhost s3 in test servers httpd.conf with a test3.com as servername and changing the other sites to tests1.com and tests2.com, and adding .htaccess also to this s3 root directory, and making a html/s3/ directory structure I populated with an index.html, etc. But, when I take the same URL (s3.com/?page=modules/product&id=521614) changing it to tests3.com/?page=modules/product&id=521614, I get s1's index page showing up in my browser. I've poked around about a day now and i cant figure out why this happens.

• How to determine if VSTO 2010 Runtime is Installed?

  - by Joel

  It was easy to check if VSTO 2005 SE was installed by just calling MsiGetProductInfo() with the product code {388E4B09-3E71-4649-8921-F44A3A2954A7}, as listed in MSDN. What is the product code for the VSTO 2010/4.0 runtime? Or is there a better way to determine if it's already installed? This is for our installation process. Thanks! Also, I am trying to figure out the same for Windows Imaging Component.

• Subclassed django models with integrated querysets

  - by outofculture

  Like in this question, except I want to be able to have querysets that return a mixed body of objects: >>> Product.objects.all() [<SimpleProduct: ...>, <OtherProduct: ...>, <BlueProduct: ...>, ...] I figured out that I can't just set Product.Meta.abstract to true or otherwise just OR together querysets of differing objects. Fine, but these are all subclasses of a common class, so if I leave their superclass as non-abstract I should be happy, so long as I can get its manager to return objects of the proper class. The query code in django does its thing, and just makes calls to Product(). Sounds easy enough, except it blows up when I override Product.__new__, I'm guessing because of the __metaclass__ in Model... Here's non-django code that behaves pretty much how I want it: class Top(object): _counter = 0 def __init__(self, arg): Top._counter += 1 print "Top#__init__(%s) called %d times" % (arg, Top._counter) class A(Top): def __new__(cls, *args, **kwargs): if cls is A and len(args) > 0: if args[0] is B.fav: return B(*args, **kwargs) elif args[0] is C.fav: return C(*args, **kwargs) else: print "PRETENDING TO BE ABSTRACT" return None # or raise? else: return super(A).__new__(cls, *args, **kwargs) class B(A): fav = 1 class C(A): fav = 2 A(0) # => None A(1) # => <B object> A(2) # => <C object> But that fails if I inherit from django.db.models.Model instead of object: File "/home/martin/beehive/apps/hello_world/models.py", line 50, in <module> A(0) TypeError: unbound method __new__() must be called with A instance as first argument (got ModelBase instance instead) Which is a notably crappy backtrace; I can't step into the frame of my __new__ code in the debugger, either. I have variously tried super(A, cls), Top, super(A, A), and all of the above in combination with passing cls in as the first argument to __new__, all to no avail. Why is this kicking me so hard? Do I have to figure out django's metaclasses to be able to fix this or is there a better way to accomplish my ends?

• Existing web-site CSS replacement (re-skinning) best-practices without changing the HTML

  - by Enigmativity

  I can see a number of other good answers to questions relating to CSS best-practices on stack overflow: How to Manage CSS Explosion CSS Conventions / Code Layout Models Are there any CSS standards that I should follow while writing my first stylesheet? What is the best method for tidying CSS? Best Practices - CSS Stylesheet Formatting But I think I have a different problem. I'm trying to "re-skin" an existing site that has been nicely built using div's and ul's, etc, and it has a good existing CSS file, but when I start making changes to the CSS I quickly find that I break the layout. My feeling is that it is very hard to get a feel for how all the CSS will work together and indeed what CSS is affecting parent and sibling elements in the HTML. So, my question is "what are the best-practices around re-skinning an existing web-site by replacing the CSS only and not modifying the existing HTML?" I can't change the classes, ids, node hierarchy, etc. An example of the particular site that I am trying to re-skin is http://demo.nopcommerce.com/. The existing CSS can be as complicated/detailed as this extract from the main CSS file: .header-selectors-wrapper { text-align: right; float: right; width: 500px; } .header-currencyselector { float: right; } .header-languageselector { float: left; } .header-taxDisplayTypeSelector { float: right; } .header-links-wrapper { float: right; text-align: right; width: 570px; } .header-links { border: solid 1px #9a9a9a; padding: 5px 5px 5px 5px; margin-bottom: 5px; display: inline-table; } .order-summary-content .cart .cart-item-row td, .wishlist-content .cart .cart-item-row td { border-bottom: 1px solid #c5c5c5; vertical-align: middle; line-height: 30px; } .order-summary-content .cart .cart-item-row td.product, .wishlist-content .cart .cart-item-row td.product { text-align: left; padding: 0px 10px 0px 10px; } .order-summary-content .cart .cart-item-row td.product a, .wishlist-content .cart .cart-item-row td.product a { font-weight: bold; } Any help would be appreciated.
