  • VCL - configuration for Magento and Varnish 3.0.2

    - by Tomas
    I would like to kindly ask if there's someone who can help me configure Varnish for Magento to reach far more hits. My current ratio from varnishstat is: cache_hit=271 cache_miss=926 I'm kindly asking this because I've googled almost every site related to this theme, but 99.9% of configurations don't work because of outdated code. Details of my set-up: I use Varnish on port 80, Apache on port 81, PageCache as Magento varnish module, APC for PHP speed and Memcached for dynamic caching. Load speed is about 1.5s on home-page (Pingdom.com average results) USA ping & 2.5s Europe. Servers are located in Toronto, Canada. EDIT: This is my full VCL configuration http://pastebin.com/885BzHCs (I just use xxx.xxx.xxx.xxx for my IPs) This is the info from the command (varnishtop -i TxHeader -I Cookie): TxHeader Cookie: frontend=965b5...(*lots of numbers); adminhtml=3ae65...(*lots of numbers); EXTERNAL_NO_CACHE=1 "(*lots of numbers)" is just my adding to the info Any idea how to avoid Varnish hitting this cookies? (If I got correctly the idea about avoiding Vanrish hitting the cookie and not caching the home page). Thank you for any help!

  • a brand new FS based on a database without using fuse

    - by Devrim
    hi all, To serve millions of files out of a single directory, being able to connect to a drive from hundreds of endpoints, and for some other reasons (to avoid gluster/nfs/all fs based networking solutions), I want to evaluate the possibility of making a filesystem that's based on a mongodb (or any other). Basically, it works like fusefs, every single file is kept in mongo gridfs. In theory, I do, mount mongodbfs /mountPoint mongodb://localhost then when i say touch /mountPoint/test.txt this file is inserted into mongodb. This FS will also store uid/gid and perms with the file, we can throw hundreds of servers to it, and no useradd will be necessary. I'm not thinking to include all the features of FS, just the ones we need. My question is, how do I start my quest in finding resources, books, links, people, developers who'd help me implement this? at least a proof of concept. Is it feasible? What should I expect as a timeline for such undertaking? Please only think about gazillion small files and folders.

  • Exchange 2007 with Android activesync

    - by lbanz
    A few of our users noticed that it will stop working intermittently for them. I didn't believe it at first until I changed my android phone and it started occuring for me. It will just stop syncing completely, it looks like the server is blocking the device completely. This mainly occurs when they are using the wifi. I've done some testing. If I switch off the wifi and use the phone data plan it will work fine. When it's on the wifi network, I try and browse to the webmail/owa page and it says page not found! I did a dns lookup and they resolve correctly. If I use another device on the same wifi network, it can access the exchange servers fine. Sometimes the wifi network will just work without any issues. But when it fails, it looks like the phone constantly checks the server every second to see if it is online even though I've got it on manual sync. I was wondering whether it tries to sync too many times and exchange thinks its a denial service attack. My old android phone that works is Froyo and the new one is Icecream. People who have reported issues seems to be newer phones. They also tested their own wifi network at home and experience the same problem. We haven't patch our exchange recently before seeing this problem. Anyone has seen this issue?

  • Random and Selective ARP blindness in VMWare ESXi 4.1

    - by Peter Grace
    We have multiple VMWare ESX servers spread out amongst our company, doing various tasks. One particular ESXi host is exhibiting very peculiar behavior. We detect it when our monitoring system (Orion) notifies us that it can no longer ping the box. Upon jumping on the local console of the guest in question, we see that it cannot ping any new addresses that aren't already in its ARP table. At first we thought that the problem was just related to one of our guests, as the problem seemed to always happen to another guest, DevRedis. However, this afternoon the problem swapped and started happening on ApacheBox rather than DevRedis. When I have been fortunate to catch the problem, I have run tcpdump on both sides of the connection (one side being vmware, the other side being a physical webserver) and have noticed the following course of events: Guest ApacheBox sends an ARP request for the physical address of server WindowsBeast WindowsBeast tenders an ARP is-at back to the network indicating its physical mac address. ApacheBox never sees the ARP is-at response. The ESX host in question is running VMware ESXi, 4.1.0, 348481 The two guests (DevRedis and ApacheBox) are both running CentOS 6.3, however they are running two separate kernel versions ( 2.6.32-279.9.1.el6.x86_64 and 2.6.32-279.el6.x86_64 ) so I'm not entirely sure it's a CentOS problem. Does anyone have any thoughts on what might cause this? Has anyone run into it before?

  • Am I able to forward traffic from an external subdomain to a specific local host?

    - by George Bowman
    I apologise in advance if the question doesn't make sense, please let me know. I've got a small LAN (~10 Virtual Servers) using Win Server 2008 as a DNS server. This is behind a smoothwall express 3.0 firewall with ports forwarded for specific services. I have a domain (123-reg) with the NS's that of afraid.org (DynamicDNS) and subdomains pointed to my (Dynamic) IP address e.g. subdomain1.example.com - 123.456.789.101. I think that adequately explains my set up. My question is, am I able to have subdomains e.g. subdomain1.example.com only point to a specific local host? Like so: subdomain1.example.com:80 - firewall(external facing) - server1.example.com:80 subdomain2.example.com:80 - firewall(external facing) - server2.example.com:80 I don't actually necessarily want to use port 80, otherwise I would just use VirtualHosts on apache, it is just an example port. Currently I can use either subdomain1.example.com OR subdomain2.example.com and they will both point to server1.example.com:80 I do not have to stay using Win Server 2008 for DNS, I am more than happy to move over to BIND if needs be, it was just easier to use Win Server 2008's DNS. I do not know if this is even possible, I have a feeling it isn't as I've only got one external IP address but any information is useful!

  • network routing between mac & virtual XP

    - by Kevin
    Hi - I have a max laptop running XP inside VirtualBox. The network is setup to be a "Bridged Adapter" so that the IPs for both the host & guest OS's are assigned by my wireless routed. My guest XP has Nortel VPN connecting to corporate lan. When this is connected, I want to allow my host Mac OS to access the corporate network. But I'm struggling. Without Nortel VPN running, I can change routing on the mac so all traffic is sent via the guest XP - this works. But once I activate the VPN, this no longer works. If I try to change the routing on mac to run through the IP address assigned to the Nortel adapter, I get a "Network is unreachable" error. Below is the output from ipconfig /all on the guest XP OS. I'm beginning to believe that what I want to do is not possible because of the way Nortel secure the VPN - but before I give up I thought I'd post the problem here.

  • shared hosting with malware, .htaccess file gets modified every 2 hours or so

    - by apache
    I spent all day today chasing malware on the shared hosting for one of my clients. The issue is as follows: Every 2 hours or so .htaccess file and all other .htaccess files gets modified, on the top of the file these lines are added: IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_REFERER} ^.*(google|ask|yahoo|youtube|wikipedia|excite|altavista|msn|aol|goto|infoseek|lycos|search|bing|dogpile|facebook|twitter|live|myspace|linkedin|flickr)\.(.*) RewriteRule ^(.*)$ http://pasla-ghwoo.ru/rqpgfap?8 [R=301,L] </IfModule> and on the bottom: ErrorDocument 400 http://pasla-ghwoo.ru/rqpgfap?8 ErrorDocument 401 http://pasla-ghwoo.ru/rqpgfap?8 ErrorDocument 403 http://pasla-ghwoo.ru/rqpgfap?8 ErrorDocument 404 http://pasla-ghwoo.ru/rqpgfap?8 ErrorDocument 500 http://pasla-ghwoo.ru/rqpgfap?8 The main problem I'm not root on the server, and cannot sudo, as this is shared hosting with 100's of websites. Typical good commands like dmesg, lsof, dtrace, chattr and many others are not available to me as I'm not root. I can't find who is modifying .htaccess files, how do I get that info? My guess is some php script is changing that which is called from outside via command and control. This seems to relate to this: http://blog.unmaskparasites.com/2009/09/11/dynamic-dns-and-botnet-of-zombie-web-servers/ How do I find out who is modifying .htaccess files without being root?

  • VMWare web UI intermittent access on CentOS

    - by PeteWilliams
    I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

  • Creating multiple SFTP users for one account

    - by Tom Marthenal
    I'm in the process of migrating an aging shared-hosting system to more modern technologies. Right now, plain old insecure FTP is the only way for customers to access their files. I plan on replacing this with SFTP, but I need a way to create multiple SFTP users that correspond to one UNIX account. A customer has one account on the machine (e.g. customer) with a home directory like /home/customer/. Our clients are used to being able to create an arbitrary number of FTP accounts for their domains (to give out to different people). We need the same capability with SFTP. My first thought is to use SSH keys and just add each new "user" to authorized_keys, but this is confusing for our customers, many of whom are not technically-inclined and would prefer to stick with passwords. SSH is not an issue, only SFTP is available. How can we create multiple SFTP accounts (customer, customer_developer1, customer_developer2, etc.) that all function as equivalents and don't interfere with file permissions (ideally, all files should retain customer as their owner)? My initial thought was some kind of PAM module, but I don't have a clear idea of how to accomplish this within our constraints. We are open to using an alternative SSH daemon if OpenSSH isn't suitable for our situation; again, it needs to support only SFTP and not SSH. Currently our SSH configuration has this appended to it in order to jail the users in their own directories: # all customers have group 'customer' Match group customer ChrootDirectory /home/%u # jail in home directories AllowTcpForwarding no X11Forwarding no ForceCommand internal-sftp # force SFTP PasswordAuthentication yes # for non-customer accounts we use keys instead Our servers are running Ubuntu 12.04 LTS.

  • Terminal emulation has stopped working. Garbage escape chars

    - by oligofren
    To enable me to do some remote administration of our servers I started using a terminal emulation program called TouchTerm Pro on my iPhone. While not the smoothest experience, it has allowed me to leave my computer behind when going out of town, which makes the slightly painful experience worthwhile. As of late, the app unfortunately no longer works. Pressing up and down keys after logging on via ssh gives me garbage like ^[[A and ^[[B. Combinations with Ctrl - like you can see in the video - no longer works either. Writing full command lines and executing by the enter key works though. Being able to search my bash history was the difference between a usable app and endless frustration, so getting it to work is essential. The app has (of course) met its end of life, not getting updated anymore. I am not quite sure, which side (client or server) that has to be "fixed"/hacked to make the control sequences work again. But is there something I can do to make it work as intended? You can see a video of TouchTerm in operation here.

  • OpenVPN-based VPN server on same system it's "protecting": feasible?

    - by Johnny Utahh
    Scenario: hosted machine (typically a VPS) serving wiki, svn, git, forums, email lists (eg: GNU mailman), Bugzilla (etc) privately to < 20 people. People not on team not allowed access. Seeking VPN-restricted access to said server. Have good user experience with OpenVPN-based servers/clients, but have yet to server-admin such systems. Otherwise, experienced Linux sysadmin. Target system: Ubuntu, probably 12.04. Seeking to put an OpenVPN process on above server to "protect" all the above-mentioned services, enabling only OpenVPN-authorized clients/processes to access above services. (Can easily acquire additional IP address(es) as needed for this setup.) Option: if absolutely needed, can employ an additional, dedicated, "VPN server" VPS simply to be my VPN server "front end." But prefer to have all server processes (VPN server plus other server apps) all running on same machine, if possible. Will consider further if dedicated-VPN-machine setup enables 1. easier installation/administration, 2. better/easier end-user experience, and/or 3. makes system significantly more secure. Any of above feasible? The main intention: create a VPN from purely-hosted resources, and not spend all the effort to make a non-VPN, secure site--which typically means "SSL wrapping" + all the continual webserver-application-update management. Let the VPN server deal with access security, and spend list time pushing said security "down" in the other apps/Apache.

  • Developing high-performance and scalable zend framework website [on hold]

    - by Daniel
    We are going to develop an ads website like http://www.gumtree.com/ (it will not be like this one but just to give you an ideea) and we are having some issues regarding performance and scalability. We are planning on using Zend Framework for this project but this is all that I'm sure off at this point. I don't think a classic approch like Zend Framework (PHP) + MySQL + Memcache + jQuery (and I would throw Doctrine 2 in there to) will fix result in a high-performance application. I was thinking on making this a RESTful application (with Zend Framework) + NGINX (or maybe MongoDB) + Memcache (or eAccelerator -- I understand this will create problems with scalability on multiple servers) + jQuery or maybe throw Backbone.js in there, a CDN for static content, a server for images and a scalable server for the requests and the rest. My questions are: - What do you think about my approch? - What solutions would you recommand for developing an high performance, scalable application expected to have a lot of traffic using PHP(Zend Framework 2)...I would be interested in your approch. I should note that I'm a Zend developer, I'm working with Zend for over 3 years, this is why I'm choosing it.

  • Error when mount the database in exchange 2010 SP1

    Hi, My company have two exchange 2010 SP1 servers with DAG configuration with OS widows server 2008 R2 in testing entironment. Today i want to test my backup possibility, so i restore the backup data to another location not original location. I dismount the database and then delete the all files under the database location. last I copy back the files from back up location to database location. When i want to mount the database.

  • DNS resolve .com domain on local domain

    - by Joost Verdaasdonk
    I'm building a local 2008 R2 domain as a test case to be able to write a roadmap for the real new domain that needs to be created soon. What I would like to know if I'm able to make a record in DNS that will point the domain name: www.example.com and example.com to one of the servers in my network. I tried creating an a-record for it but that doesn't work. To be honest I'm not even sure if this is possible? So can I do this? That way I would be able to fully test all our services (and webb app) offline before I build the real domain and switch the DNS records at the provider. Some advice if possible and where to start is appreciated. The solution (Thanks Brent): Create new Forward lookup zone pointing to example.com Create empty A record pointing to IP of the webserver you are targeting If www is needed create A record with Name: www and IP of your webserver sub domains repeat the process but then with names for example: sub or www.sub (and ip your webserver) Be aware of the DNS Cache while you are in this process. Things can take time or do the following: Right click the server and choose clear cache in CMD: ipconfig /flushdns (to flush the client cache)

  • Cisco IOS ACL: Don't permit incoming connections just because they are from port 80

    - by cjavapro
    I am going much based on my memory and I may not be correct on all of this. On a Cisco 851 (IOS) that uses a BVI or a bridge-route (the servers on the inside are configured with static and public IP addresses). I would apply two access lists (both end with deny ip any any log) on FastEthernet4 (the WAN port). There would be one for FA4 in and another for FA4 out. FA4 out would have a line like access-list 110 permit 98.76.54.0 0.0.0.255 gt 1023 any eq http I think this means from 98.76.54.* with a from port of at least 1024 can connect to any other machine with a destination port 80. So, then I have to allow the response to the HTTP connection. FA4 in would have a line like access-list 120 permit any eq http 98.76.54.0 0.0.0.255 gt 1023 Now the problem with that is that anybody on the outside can set their from port to port 80 and then connect to any inside port that is at least 1024. How do we prevent this and require the incoming data to be a response to the outgoing data.

  • My bios datetime is resetting to 2002, what should I do?

    - by Thierry Lam
    I bought my PC brand new in mid-2006. I'm currently dual booting Win XP 32 bits and Ubuntu Karmic Desktop. Over the last few days, when I boot up my computer, it tells me that my bios time is not set. I now have 2 choices for booting in: Windows first: I can safely get into Windows but the date now shows 2002/01/01 at 00:00. From there, Windows will not sync its time to its servers, I have to manually advance the date myself. I can also advance the date from the bios at startup. Ubuntu first: Since the time date is still set at 2002, the boot system cannot find my linux partition. I can fix that issue by booting to Windows, set the date properly and the linux issue will be fixed automatically. The above two issues can also be fixed if I manually set the bios date/time manually when I turn on my computer. It's annoying to do that every single day since I shut down my PC daily. Am I having an OS issue or a hardware issue? How can I resolve this problem?

  • DPM server 2010 Attach agent error : administrator privileges missing?

    - by Michael
    I’m hoping you would be able to help me out with this little problem I’m having. I installed DPM 2010 in our test environment to test backups on Exchange 2010 servers. The environment includes : 1xDC 2x Exchange Server 2010 1x DPM 2010 server All of these are running on Microsoft server 2008 R2 Virtual machines. The host machines are using Hyper-v. So the problem goes like this : 1- I tried to install the agents from the DPM server GUI, which failed saying I didn’t have the correct permissions. 2- So then I tried the manual installation using the commands from : the Microsoft site http://technet.microsoft.com/en-us/library/bb870935.aspx 3- The agent installation worked but when I get to attaching the agents to the DPM server it still gives me the error saying that the specified account does not have administrator rights. 4- I tried the Domain admin, users who are domain admin + local admin, single local admins. 5- I have turned off the windows firewall and made sure all the services are running. So now I’m out of ideas and really need help, the agent attach to the DPM server is the last thing that is holding me back from deploying everything to the production site. Any help would be really appreciated.

  • Caching all files in varnish

    - by csgwro
    I want my varnish servers to cache all files. At backend there is lighttpd hosting only static files, and there is an md5 in the url in case of file change, ex. /gfx/Bird.b6e0bc2d6cbb7dfe1a52bc45dd2b05c4.swf). However my hit ratio is very poorly (about 0.18) My config: sub vcl_recv { set req.backend=default; ### passing health to backend if (req.url ~ "^/health.html$") { return (pass); } remove req.http.If-None-Match; remove req.http.cookie; remove req.http.authenticate; if (req.request == "GET") { return (lookup); } } sub vcl_fetch { ### do not cache wrong codes if (beresp.status == 404 || beresp.status >= 500) { set beresp.ttl = 0s; } remove beresp.http.Etag; remove beresp.http.Last-Modified; } sub vcl_deliver { set resp.http.expires = "Thu, 31 Dec 2037 23:55:55 GMT"; } I have made an performance tuning: DAEMON_OPTS="${DAEMON_OPTS} -p thread_pool_min=200 -p thread_pool_max=4000 -p thread_pool_add_delay=2 -p session_linger=100" The main url which is missed is... /health.html. Is that forward to backend correctly configured? Disabling health checking hit ratio increases to 0.45. Now mostly "/crossdomain.xml" is missed (from many domains, as it is wildcard). How can I avoid that? Should I carry on other headers like User-Agent or Accept-Encoding? I thing that default hashing mechanism is using url + host/IP. Compression is used at the backend. What else can improve performance?

  • Converting a Windows 2003 server

    - by Jim Bass
    We have a legacy database system based upon MS SQL running on Windows Server 2003. The client software will only run on Windows XP. We have recently had success converting a client into a virtual machine and running it under Fusion on Mac minis. So far, it is working incredibly well. So well, in fact, that we are now considering trying to convert the server to a virtual machine. This raises several questions, though: 1. The server uses a raid array. Does the VM virtualize the raid array? I only ask because in my experience Windows products don't like it when you change core hardware. 2. Is there any reason why running SQL server on a virtual machine won't work? It will be up 24/7. 3. Is there a different converter for servers? 4. Will I have to track down the licensing for MS SQL and Server 2003 or will they come across ok? 5. The company that designed the software is no longer in business. There is some fear that the software is somehow tied to the hardware configuration. We bought the hardware, but their engineers came out and configured the system. Will the virtual machine be able to spoof particular chip sets? Thanks! Jim Bass

  • central apache log analysis of many hosts

    We have 30+ apache httpd servers, and are looking to perform analysis on the logs both for historical trending and near "real time" monitoring/alerting. I'm mainly interested in things like error rates (4xx/5xx), response time, overall request rate, etc. but it would also be very useful to pull out more compute-intensive statistics like unique client IPs and user agents per unit of time. I'm leaning towards building this as a centralized collector/server/storage, and am also considering the possibility of storing non-apache logs (i.e. general syslog, firewall logs, etc.) in the same system. Obviously a large part of this will probably have to be custom (at least the connection between pieces and the parsing/analysis we do), but I haven't been able to find much information on people who have done stuff like this, at least at shops smaller than Google/Facebook/etc. who can throw their log data into a hundred-node compute cluster and run Map/Reduce on it. The main things I'm looking for are: - All open source - Some way of collecting logs from apache machines that isn't too resource-intensive, and transports them relatively quickly over the network - Some way of storing them (NoSQL? key-value store?) on the backend, for a given amount of time (and then rolling them up into historical averages) - In the middle of this, a way of graphing in near-real-time (probably also with some statistical analysis on it) and hopefully alerting off of those graphs. Any suggestions/pointers/ideas, to either "products"/projects or descriptions of how other people do this would be greatly helpful. Unfortunately, we're not exactly a new-age-y devops shop, lots of old stuff, homogeneous infrastructure, and strained boxes.

  • What is the oldest hardware still in production use? How is it kept running?

    - by sleske
    In the spirit of the question What is your oldest hardware that still works?, I'd like to ask: What is the oldest hardware you know that is still in production use? And what challenges did you (or someone else) face in keeping it running (scarce documentation, no support, no spare parts available...)? Most organizations will retire / upgrade software and hardware after 5-10 years, but sometimes old software is kept running on old boxes, because it "just works". I once worked at a client site that was running a critical piece of (in-house developed) business software on a single server running HP-UX. The server was old (ca. 12-13 years), but fortunately still running without problems; however, getting spares would have been very difficult, and since software installation was undocumented, any significant system changes or even new hardware might have caused significant downtime and data loss. We eventually managed to replace it, but this is not always possible. I also read that many organizations still run decade-old mainframe hardware, particularly for highly customized systems controlling industrial machines or power plants. Which old hardware have you encountered? How did you manage these challenges? Related question: http://serverfault.com/questions/82467/should-old-servers-be-retired

  • Does Active Directory on Server 2003 R2 support IPv6 subnets in Sites and Services?

    - by NorbyTheGeek
    I've been experimenting with IPv6 at our organization. The domain controllers (all 2003 R2) and most of the servers (2003 R2 / 2008 / 2008 R2) have IPv6 configured. We have a subnet assigned through a tunnel provider. Currently, the only workstation that is running IPv6 is mine. (Windows 7) I have been noticing that my workstation is picking domain controllers in other sites for things like DFS, and I finally realized that I don't have the IPv6 subnets set up in Active Directory Sites and Services (ADSS). But when I try to add a IPv6 prefix in ADSS, it tells me: Windows cannot create the object 2001:xxxx:xxxx:xxxx::/64 because: The object name has bad syntax. I believe I may be using the 2008 version of the admin tools (ADSS reports version 6.1.7601.17514) so I'm wondering if maybe my 2003 R2 Active Directory schema doesn't support configuring IPv6 subnets in ADSS. Is this true? UPDATE Even with 2008 R2 schema in Active Directory, I'm having the same problem. How can I get my IPv6 subnets into Sites and Services?

  • CloudFront with Custom Origin and ELB

    - by kmfk
    We are using CloudFront for our static assets but also wanted to allow for Gzip. We set up a new distribution with a custom origin pointing back to our application servers which are behind a elastic load balancer. We manually keep the files in sync across the cluster and update them when we publish. However, with this set up, we get nothing but Miss and RefreshHits from CloudFront, which so far has defeated the purpose. Is there any additional settings in order to use an ELB as your custom origin? In the docs, it references this as a viable solution. It appears when we point the distribution to a single server in our production cluster, cloudfront properly caches our assets. Is it possible that the sticky sessions cookie and the subsequent header that gets added by it could be an issue? Cache-Control: no-cache="set-cookie" //Added by load balancer Any ideas? FYI - currently, we have our custom origin pointing to a single EC2 instance, so caching is working correctly - in case you try to curl the file below. Example headers: curl -I http://static.quick-cdn.com/css/9850999.css HTTP/1.0 200 OK Accept-Ranges: bytes Cache-Control: max-age=3700 Cache-Control: no-cache="set-cookie" Content-Length: 23038 Content-Type: text/css Date: Thu, 12 Apr 2012 23:03:52 GMT Last-Modified: Thu, 12 Apr 2012 23:00:14 GMT Server: Apache/2.2.17 (Ubuntu) Vary: Accept-Encoding X-Cache: RefreshHit from cloudfront X-Amz-Cf-Id: K_q7Zy3_jdzlEJ85ukELVtdx1GmuXqApAbZZ7G0fPt0mxRMqPKX5pQ==,RzJmPku-rEIO9WlvuSoKa8hiAaR3dLk5KC4cQMWWrf_MDhmjWe8n6A== Via: 1.0 28c34f9fbf559a21ee16594849e4fc9c.cloudfront.net (CloudFront) Connection: close

  • Licensing SQL Server 2012 Reporting Services w/ SharePoint 2010

    - by Evan M.
    Here's my situation: I have 1 VM that is running SharePoint 2010 SP1. I have a different physical server that is running SQL Server 2008 R2 that hosts all the configuration and content database for SharePoint. Now, we want to start providing BI capabilities to our users with SharePoint and SQL Server. With it's new features, 2012 is the obvious way to go. To support this, I'm looking to build a new VM that will have SQL Server 2012 installed w/ Analysis services and SSIS, which will be the platform that gets our data from our Oracle databases, puts it in a warehouse hosted by the SQL 2012 instance, and is put into cubes. What's getting me about the platform is licensing for Reporting Services and PowerPivot. My plan was to install SSRS and PowerPivot on the current SharePoint server. But my understanding of the licensing means that instead of the new SQL server being licensed, I'd have to license both new server, and the SharePoint server. Conversely, I could install SharePoint onto the SQL server, and only have to get a second SP license, but then I'd have the added complexity of deploying a separated application server, and combines my data and application servers. Is my licensing understanding correct, or can I have SSRS and PowerPivot installed separately without incurring additional licensing costs?
