  • nginx can't load images,css,js

    - by EquinoX
    When I point to a URL in nginx where it has images extension such as: http://50.56.81.42/phpMyAdmin/themes/original/img/logo_right.png (as example) it gives me the 404 error as it can't find the file, but the file is actually there. What is potentially wrong? UPDATE: Here's the error log that I was able to pull out: 2011/02/27 05:53:29 [error] 18679#0: *225 open() "/usr/local/nginx/html/phpMyAdmin/js/mooRainbow/mooRainbow.css" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/js/mooRainbow/mooRainbow.css HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:53:29 [error] 18679#0: *226 open() "/usr/local/nginx/html/phpMyAdmin/print.css" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/print.css HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:53:29 [error] 18679#0: *228 open() "/usr/local/nginx/html/phpMyAdmin/themes/original/img/logo_right.png" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/themes/original/img/logo_right.png HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:53:29 [error] 18679#0: *223 open() "/usr/local/nginx/html/phpMyAdmin/themes/original/img/b_help.png" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/themes/original/img/b_help.png HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:53:29 [error] 18679#0: *227 open() "/usr/local/nginx/html/phpMyAdmin/themes/original/img/s_warn.png" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/themes/original/img/s_warn.png HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:53:29 [error] 18679#0: *227 open() "/usr/local/nginx/html/phpMyAdmin/favicon.ico" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/favicon.ico HTTP/1.1", host: "50.56.81.42" 2011/02/27 05:54:39 [error] 18679#0: *237 open() "/usr/local/nginx/html/phpMyAdmin/print.css" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/print.css HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:54:39 [error] 18679#0: *235 open() "/usr/local/nginx/html/phpMyAdmin/js/mooRainbow/mooRainbow.css" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/js/mooRainbow/mooRainbow.css HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:54:39 [error] 18679#0: *238 open() "/usr/local/nginx/html/phpMyAdmin/themes/original/img/logo_right.png" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/themes/original/img/logo_right.png HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:54:39 [error] 18679#0: *239 open() "/usr/local/nginx/html/phpMyAdmin/themes/original/img/b_help.png" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/themes/original/img/b_help.png HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:54:39 [error] 18679#0: *233 open() "/usr/local/nginx/html/phpMyAdmin/themes/original/img/s_warn.png" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/themes/original/img/s_warn.png HTTP/1.1", host: "50.56.81.42", referrer: "http://50.56.81.42/phpMyAdmin/main.php" 2011/02/27 05:54:39 [error] 18679#0: *233 open() "/usr/local/nginx/html/phpMyAdmin/favicon.ico" failed (2: No such file or directory), client: 70.176.18.156, server: localhost, request: "GET /phpMyAdmin/favicon.ico HTTP/1.1", host: "50.56.81.42" Here's my nginx.conf file, in case I am missing something: #user nobody;

  • Throughput tool with decent graphing.

    - by Cory J
    I've been looking through some of the tools available for measuring network throughput, namely iperf, bwping, ttcp, etc. I am planning on doing throughput tests over a long period of time, so what I really need is good graphing output, preferably rrd graphs. The Jperf frontend for iperf will generate a graph, and bmon has a nice command-line graph, but these simply count seconds since the test was started. I am trying to measure trends in throughput over times of the day, so a graph with times and days is necessary. So a way to get iperf to log to RRDs would be best, if this isn't possible could someone point me toward another solution?

  • CPU & Memory Usage Log & Performance

    - by wittythotha
    I want to have an idea of the amount of CPU and memory that is being used. I have a website hosted using IIS, and have clients connecting to it. I want to find out the amount of load that the CPU, RAM and the network has when multiple clients connect. I tried out using tools like Fiddler, the inbuilt Resource Manager, and also some other applications I found on the internet. I just want to keep track of all these data in a file, so I can plot out a graph and find out how the CPU, etc. is performing. I read a few other posts, but didn't find anything that solves the problem. Is there good CPU / Memory Logging tool available, just to plot a graph of the usage, etc.? EDIT : I want to know of some tool that can save the performance details in a log file, so that I can use it to plot a graph, etc.

  • how to use winpcap to send EAPOL packets on windows 7 with wireless card?

    - by caimengru0807
    I want to implement a 802.1X wireless client on Windows 7 using PEAP/MSCHAPv2. The 802.1X protocol is a data link layer protocol, it uses the EAPOL protocol to encapsulate the packets. I use the WinPcap to send and receive the EAPOL packets, however I fail to do it with the wireless NIC. It can work fine to send the EAPOL packets use wired NIC. It can also work fine to send the EAPOL packets on Windows XP using wireless NIC. So what's wrong with it on Windows 7?

  • Dual monitor webbrowsing with Firefox - Addon that opens links on the other window?

    - by raegadfsgfsdg
    I often browse news aggressors like Reddit.com and I want to be able to have one Firefox window open on each of my two screens, and when I middle click on a link on my left screen, it will open up the tab on my right firefox window. I know that there are some plugins that can open up new windows, but if I do that I'll have to many windows open and I'd rather manage my open news stories via tab bars rather than with windows (clearer, more efficient to browse, and easier to bookmark). Is there a Firefox addon with which I can middle click on a link and it will open it in a new tab in my other window?

  • Debian server doesn't free memory after backup

    - by stan31337
    I have production server that is running Debian 6.0.6 Squeeze #uname -a Linux debsrv 2.6.32-5-xen-amd64 #1 SMP Sun Sep 23 13:49:30 UTC 2012 x86_64 GNU/Linux Every day cron executes backup script as root: #crontab -e 0 5 * * * /root/sites_backup.sh > /dev/null 2>&1 #nano /root/sites_backup.sh #!/bin/bash str=`date +%Y-%m-%d-%H-%M-%S` tar pzcf /home/backups/sites/mysite-$str.tar.gz /var/sites/mysite/public_html/www mysqldump -u mysite -pmypass mysite | gzip -9 > /home/backups/sites/mysite-$str.sql.gz cd /home/backups/sites/ sha512sum mysite-$str* > /home/backups/sites/mysite-$str.tar.gz.DIGESTS cd ~ Everything works perfectly, but I notice that Munin's memory graph shows increase of cache and buffers after backup. Then I just download backup files and delete them. After deletion Munin's memory graph returns cache and buffers to the state that was before backup. Here's Munin graph: Unfortunately I don't have enough rep to add image here. So here's a link:

  • Can someone explain the "use-cases" for the default munin graphs?

    - by exhuma
    When installing munin, it activates a default set of plugins (at least on ubuntu). Alternatively, you can simply run munin-node-configure to figure out which plugins are supported on your system. Most of these plugins plot straight-forward data. My question is not to explain the nature of the data (well... maybe for some) but what is it that you look for in these graphs? It is easy to install munin and see fancy graphs. But having the graphs and not being able to "read" them renders them totally useless. I am going to list standard plugins which are enabled by default on my system. So it's going to be a long list. For completeness, I am also going to list plugins which I think to understand and give a short explanation as to what I think it's used for. Pleas correct if I am wrong with any of them. So let me split this questions in three parts: Plugins where I don't even understand the data Plugins where I understand the data but don't know what I should look out for Plugins which I think to understand Plugins where I don't even understand the data These may contain questions that are not necessarily aimed at munin alone. Not understanding the data usually mean a gap in fundamental knowledge on operating systems/hardware.... ;) Feel free to respond with a "giyf" answer. These are plugins where I can only guess what's going on... I hardly want to look at these "guessing"... Disk IOs per device (IOs/second)What's an IO. I know it stands for input/output. But that's as far as it goes. Disk latency per device (Average IO wait)Not a clue what an "IO wait" is... IO Service TimeThis one is a huge mess, and it's near impossible to see something in the graph at all. Plugins where I understand the data but don't know what I should look out for IOStat (blocks/second read/written)I assume, the thing to look out for in here are spikes? Which would mean that the device is in heavy use? Available entropy (bytes)I assume that this is important for random number generation? Why would I graph this? So far the value has always been near constant. VMStat (running/I/O sleep processes)What's the difference between this one and the "processes" graph? Both show running/sleeping processes, whereas the "Processes" graph seems to have more details. Disk throughput per device (bytes/second read/written) What's thedifference between this one and the "IOStat" graph? inode table usageWhat should I look for in this graph? Plugins which I think to understand I'll be guessing some things here... correct me if I am wrong. Disk usage in percent (percent)How much disk space is used/remaining. As this is approaching 100%, you should consider cleaning up or extend the partition. This is extremely important for the root partition. Firewall Throughput (packets/second)The number of packets passing through the firewall. If this is spiking for a longer period of time, it could be a sign of a DOS attack (or we are simply recieving a large file). It can also give you an idea about your firewall performance. If it's levelling out and you need more "power" you should consider load balancing. If it's levelling out and see a correlation with your CPU load, it could also mean that your hardware is not fast enough. Correlations with disk usage could point to excessive LOG targets in you FW config. eth0 errors (packets in/out)Network errors. If this value is increasing, it could be a sign of faulty hardware. eth0 traffic (bits/second in/out)Raw network traffic. This should correlate with Firewall throughput. number of threadsAn ever-increasing value might point to a process not properly closing threads. Investigate! processesBreakdown of active processes (including sleeping). A quick spike in here might point to a fork-bomb. A slowly, but ever-increasing value might point to an application spawning sub-processes but not properly closing them. Investigate using ps faux. process priorityThis shows the distribution of process priorities. Having only high-priority processes is not of much use. Consider de-prioritizing some. cpu usageFairly straight-forward. If this is spiking, you may have an attack going on, or a process is hogging the CPU. Idf it's slowly increasing and approaching max in normal operations, you should consider upgrading your hardware (or load-balancing). file table usageNumber of actively open files. If this is reaching max, you may have a process opening, but not properly releasing files. load averageShows an summarized value for the system load. Should correlate with CPU usage. Increasing values can come from a number of sources. Look for correlations with other graphs. memory usageA graphical representation of you memory. As long as you have a lot of unused+cache+buffers you are fine. swap in/outShows the activity on your swap partition. This should always be 0. If you see activity on this, you should add more memory to your machine!

  • Mac-like alt-tab replacement for Windows 7?

    - by calavera
    Is there an alt-tab replacement for windows that works in the same manner as command-tab and command-tick on OS X? example of what I'd like to do: If I hit alt-tab, I'd like to switch between open applications, rather than all windows currently open. If I hit alt-tick, I'd like to switch between open windows of the same application. VistaSwitcher is almost there, in that it allows you to alt-tick switch between windows of the same app. So if I have 4 firefox windows open and one of them is my active window, I can alt-tick to switch between those 4 while ignoring any other open apps. However, VistaSwitcher's alt-tab functionality is similar to stock Windows alt-tab, where you cycle through all open windows, regardless of whether there are multiple instances of certain applications.

  • FTP v/s SFTP v/s FTPS

    - by susmits
    We're setting up a web server at our workspace. In conjunction, we're planning to install an FTP server, however I'm stuck at what protocol to employ -- FTP, SFTP or FTPS. I googled around, trying to see what protocol offers what, coming across articles like this, but I can't make up my mind. Only simple, once-in-a-while file transfer is desired; however, security is a concern since the file server is intended to be accessible from the internet. What protocol is the most apt for my use, and why?

  • Get source and destination of outbound traffic in pfSense

    - by maxsilver
    I'm looking at the traffic graph in pfSense (Version 1.2.2), which we're using as a router / NAT / ect on our network. Recently, I'm seeing a sudden, constant spike of 15 - 30kbps traffic outbound, that is unusual for our network (normally its below 2kbps, we're mostly all inbound traffic) Is there any way to determine what the source of this traffic is, or where it's going? (Just an internal IP address for source, and external IP address for destination would be all I need) I've already tried switching the traffic graph to 'LAN' and watching the host list on the right side, but it seems ... flakey. The numbers it shows seem to fade in and out at random, and the values never add up to anywhere near the graph values. I'm not allowed to post the image, but a photo is available at - http://imgur.com/QYjKI.png

  • Problem opening password encrypted .docx file on Word 2003

    - by molecule
    Hi all, I am having a problem opening a .docx file on my Word 2003. I have installed the Compatibility pack for 2007 but when i try to open this particular file, I receive the error "Word experienced an error trying to open the file. Try these suggestions. 1. Check the file permissions for the document, 2. Make sure there is sufficient free memory and disk space, 3. Open the file with the Text Recovery converter. I do not think it is any of the errors as I am able to open it on a different PC with Word 2003 as well. I also do not have any issues opening any non-password encrypted .docx files. Has anyone experienced the same issue? Most posts on the internet relate to "open and repair" but as mentioned, I am able to open this file on another PC without any problems. Any advice is greatly appreciated. Thanks, George

  • Excel chart: How to reverse the X axis of time series data

    - by JohnnyLambada
    In Excel 2003, I have a time series from a financial report that goes something like this: 2007 2006 2005 Amount 300 200 100 I want to create a graph of the time series that looks something like this (please excuse the ugly ascii graph): 300| .x | ... 200| .x.. | ... 100| x |____________________ 0 2005 2006 2007 But intead of getting an upward sloping graph, excel wants to put my time series in reverse (the way it actually appears in the spreadsheet). Is there any way to make excel display the x axis in reverse of the way it normally does? I've tried manually reversing the range in the chart dialog (changing a range of B1:D3 to D3:B1), but excel just puts it back.

  • Statsd, Graphite and graphs

    - by w00t
    I've setup Graphite and statsd and both are running well. I'm using the example-client.py from graphite/examples to measure load values and it's OK. I started doing tests with statsd and at first it seemed ok because it generated some graphs but now it doesn't look quite well. First, this is my storage-schema.conf: pattern = .* retentions = 10:2160,60:10080,600:262974 I'm using this command to send data to statsd: echo 'ssh.invalid_users:1|c'| nc -w 1 -u localhost 8126 it executes, I click Update Graph in the Graphite web interface, it generates a line, hit again Update and the line disappears. If I execute the previous command 5 times, the graph line will reach 2 and it will actually save it. Again running the same command two times, graph line reaches 2 and disappears. I can't find what I have misconfigured. The intended use is this: tail -n 0 -f /var/log/auth.log|grep --line-buffered "Invalid user" | while read line; do echo "ssh.invalid_users:1|c" | nc -w 1 -u localhost 8126; done

  • Automatically detecting temperature sensors on startup (Ubuntu 10.10)

    - by dpitch40
    I am very close to achieving my goal of setting up a CPU temperature graph that is displayed in the top panel of my desktop. I have the applet and have gotten it to graph temperatures, which appear to be being sensed correctly. However, my machine doesn't find its temperature sensors by default; I have to run sudo modprobe coretemp for the sensors command to work, then log off and back in before the graph applet starts displaying my temperatures. I am wondering if I can somehow tell the kernel to load the coretemp module on startup so I don't have to keep doing these extra steps. I have tried putting this command in my startup applications, but I think its need for root permission is keeping this from working. Is there a way to set up startup applications with root permission, or some other way to ensure that this module is loaded at startup? If anyone is curious, I'm running 64-bit Ubuntu 10.10 on a Lenovo G770 laptop with a Core i5 processor and the 2.6.35 kernel.

  • Network Monitoring Tool Recommendation

    - by user42801
    Hello, My company is looking for a monitoring app/tool that would allow us to capture and graph statistics on network performance. As a starting point, we would like to ping remote host(s) and gateway(s) from several of our servers, grab an average of the ping times from each of our servers to the remote host(s), and then graph it (preferably in a central location). Also, we would like to be able to graph the results for time frames as short as a week to as long as 6 months. It is reasonable to expect that we would ask more of the selected monitoring app/tool as we come up with other key network performance indicators in the future. So an app with great flexibility and features would be ideal. Upon first glance, Cacti looks like it might be a fit. Any other recommendations? Thanks in advance for any input.

  • Work Item Visualizer for TFS 2010 - New Extension

    - by MikeParks
    I released another new extension to the Visual Studio Gallery again today called Work Item Visualizer for TFS 2010. I've only heard positive things about it so far, hopefully it stays that way :) Basically, it creates a diagram of all work items linked to a work item ID which the user specifies in a search box. This extension was coded using DGML (the same graph rendering language used for the Visual Studio 2010 Architecture Tools). It was pretty cool getting a chance to create something using some of the newest technology out there. Well, I just wanted to throw a blog up to get the word out on it a little more. If you're using Visual Studio 2010 with Team Foundation Server 2010, feel free to check it out! Thanks everyone. Download Link: http://visualstudiogallery.msdn.microsoft.com/en-us/a35b6010-750b-47f6-a7a5-41f0fa7294d2   What it does: ·         Creates a DGML graph to visualize linked TFS Work Items by entering a Work Item ID in the toolbar search box   How it benefits you: ·         Allows you to easily analyze the hierarchy of your TFS Work Items ·         Gain the ability to perform basic risk/impact analysis when creating or editing Work Items ·         Great for meetings in the case that you need to discuss the entire scope of linked Work Items ·         Easier project planning ·         Eliminates the need to create TFS queries or reports to view tree of Work Items ·         Easily lets you see the entire tree of work items linked to the one you’re working on   Navigation Tips: ·         Use Ctrl + Mouse Wheel Scroll to zoom in and out ·         Use Ctrl + Left Mouse click (and hold) to move document around ·         Right click on DGML area for more options (Like copy image or viewing in groups) ·         Clicking on each node highlights that node and the links connected to it ·         Colors in the legend can be changed ·         When work item nodes are deleted, the view is automatically updated ·         Double clicking on work item node will open up the Work Items URL   Try it out on work items that have several of links and let us know what you think. A big thanks goes out to everyone working on the http://visualization.codeplex.com/ project for publishing the source code on CodePlex which really helped me learn how DGML (Directed Graph Markup Language - New to Visual Studio 2010 Architecture Tools) works!    - Mike

  • How to Avoid Your Next 12-Month Science Project

    - by constant
    While most customers immediately understand how the magic of Oracle's Hybrid Columnar Compression, intelligent storage servers and flash memory make Exadata uniquely powerful against home-grown database systems, some people think that Exalogic is nothing more than a bunch of x86 servers, a storage appliance and an InfiniBand (IB) network, built into a single rack. After all, isn't this exactly what the High Performance Computing (HPC) world has been doing for decades? On the surface, this may be true. And some people tried exactly that: They tried to put together their own version of Exalogic, but then they discover there's a lot more to building a system than buying hardware and assembling it together. IT is not Ikea. Why is that so? Could it be there's more going on behind the scenes than merely putting together a bunch of servers, a storage array and an InfiniBand network into a rack? Let's explore some of the special sauce that makes Exalogic unique and un-copyable, so you can save yourself from your next 6- to 12-month science project that distracts you from doing real work that adds value to your company. Engineering Systems is Hard Work! The backbone of Exalogic is its InfiniBand network: 4 times better bandwidth than even 10 Gigabit Ethernet, and only about a tenth of its latency. What a potential for increased scalability and throughput across the middleware and database layers! But InfiniBand is a beast that needs to be tamed: It is true that Exalogic uses a standard, open-source Open Fabrics Enterprise Distribution (OFED) InfiniBand driver stack. Unfortunately, this software has been developed by the HPC community with fastest speed in mind (which is good) but, despite the name, not many other enterprise-class requirements are included (which is less good). Here are some of the improvements that Oracle's InfiniBand development team had to add to the OFED stack to make it enterprise-ready, simply because typical HPC users didn't have the need to implement them: More than 100 bug fixes in the pieces that were not related to the Message Passing Interface Protocol (MPI), which is the protocol that HPC users use most of the time, but which is less useful in the enterprise. Performance optimizations and tuning across the whole IB stack: From Switches, Host Channel Adapters (HCAs) and drivers to low-level protocols, middleware and applications. Yes, even the standard HPC IB stack could be improved in terms of performance. Ethernet over IB (EoIB): Exalogic uses InfiniBand internally to reach high performance, but it needs to play nicely with datacenters around it. That's why Oracle added Ethernet over InfiniBand technology to it that allows for creating many virtual 10GBE adapters inside Exalogic's nodes that are aggregated and connected to Exalogic's IB gateway switches. While this is an open standard, it's up to the vendor to implement it. In this case, Oracle integrated the EoIB stack with Oracle's own IB to 10GBE gateway switches, and made it fully virtualized from the beginning. This means that Exalogic customers can completely rewire their server infrastructure inside the rack without having to physically pull or plug a single cable - a must-have for every cloud deployment. Anybody who wants to match this level of integration would need to add an InfiniBand switch development team to their project. Or just buy Oracle's gateway switches, which are conveniently shipped with a whole server infrastructure attached! IPv6 support for InfiniBand's Sockets Direct Protocol (SDP), Reliable Datagram Sockets (RDS), TCP/IP over IB (IPoIB) and EoIB protocols. Because no IPv6 = not very enterprise-class. HA capability for SDP. High Availability is not a big requirement for HPC, but for enterprise-class application servers it is. Every node in Exalogic's InfiniBand network is connected twice for redundancy. If any cable or port or HCA fails, there's always a replacement link ready to take over. This requires extra magic at the protocol level to work. So in addition to Weblogic's failover capabilities, Oracle implemented IB automatic path migration at the SDP level to avoid unnecessary failover operations at the middleware level. Security, for example spoof-protection. Another feature that is less important for traditional users of InfiniBand, but very important for enterprise customers. InfiniBand Partitioning and Quality-of-Service (QoS): One of the first questions we get from customers about Exalogic is: “How can we implement multi-tenancy?” The answer is to partition your IB network, which effectively creates many networks that work independently and that are protected at the lowest networking layer possible. In addition to that, QoS allows administrators to prioritize traffic flow in multi-tenancy environments so they can keep their service levels where it matters most. Resilient IB Fabric Management: InfiniBand is a self-managing network, so a lot of the magic lies in coming up with the right topology and in teaching the subnet manager how to properly discover and manage the network. Oracle's Infiniband switches come with pre-integrated, highly available fabric management with seamless integration into Oracle Enterprise Manager Ops Center. In short: Oracle elevated the OFED InfiniBand stack into an enterprise-class networking infrastructure. Many years and multiple teams of manpower went into the above improvements - this is something you can only get from Oracle, because no other InfiniBand vendor can give you these features across the whole stack! Exabus: Because it's not About the Size of Your Network, it's How You Use it! So let's assume that you somehow were able to get your hands on an enterprise-class IB driver stack. Or maybe you don't care and are just happy with the standard OFED one? Anyway, the next step is to actually leverage that InfiniBand performance. Here are the choices: Use traditional TCP/IP on top of the InfiniBand stack, Develop your own integration between your middleware and the lower-level (but faster) InfiniBand protocols. While more bandwidth is always a good thing, it's actually the low latency that enables superior performance for your applications when running on any networking infrastructure: The lower the latency, the faster the response travels through the network and the more transactions you can close per second. The reason why InfiniBand is such a low latency technology is that it gets rid of most if not all of your traditional networking protocol stack: Data is literally beamed from one region of RAM in one server into another region of RAM in another server with no kernel/drivers/UDP/TCP or other networking stack overhead involved! Which makes option 1 a no-go: Adding TCP/IP on top of InfiniBand is like adding training wheels to your racing bike. It may be ok in the beginning and for development, but it's not quite the performance IB was meant to deliver. Which only leaves option 2: Integrating your middleware with fast, low-level InfiniBand protocols. And this is what Exalogic's "Exabus" technology is all about. Here are a few Exabus features that help applications leverage the performance of InfiniBand in Exalogic: RDMA and SDP integration at the JDBC driver level (SDP), for Oracle Weblogic (SDP), Oracle Coherence (RDMA), Oracle Tuxedo (RDMA) and the new Oracle Traffic Director (RDMA) on Exalogic. Using these protocols, middleware can communicate a lot faster with each other and the Oracle database than by using standard networking protocols, Seamless Integration of Ethernet over InfiniBand from Exalogic's Gateway switches into the OS, Oracle Weblogic optimizations for handling massive amounts of parallel transactions. Because if you have an 8-lane Autobahn, you also need to improve your ramps so you can feed it with many cars in parallel. Integration of Weblogic with Oracle Exadata for faster performance, optimized session management and failover. As you see, “Exabus” is Oracle's word for describing all the InfiniBand enhancements Oracle put into Exalogic: OFED stack enhancements, protocols for faster IB access, and InfiniBand support and optimizations at the virtualization and middleware level. All working together to deliver the full potential of InfiniBand performance. Who else has 100% control over their middleware so they can develop their own low-level protocol integration with InfiniBand? Even if you take an open source approach, you're looking at years of development work to create, test and support a whole new networking technology in your middleware! The Extras: Less Hassle, More Productivity, Faster Time to Market And then there are the other advantages of Engineered Systems that are true for Exalogic the same as they are for every other Engineered System: One simple purchasing process: No headaches due to endless RFPs and no “Will X work with Y?” uncertainties. Everything has been engineered together: All kinds of bugs and problems have been already fixed at the design level that would have only manifested themselves after you have built the system from scratch. Everything is built, tested and integrated at the factory level . Less integration pain for you, faster time to market. Every Exalogic machine world-wide is identical to Oracle's own machines in the lab: Instant replication of any problems you may encounter, faster time to resolution. Simplified patching, management and operations. One throat to choke: Imagine finger-pointing hell for systems that have been put together using several different vendors. Oracle's Engineered Systems have a single phone number that customers can call to get their problems solved. For more business-centric values, read The Business Value of Engineered Systems. Conclusion: Buy Exalogic, or get ready for a 6-12 Month Science Project And here's the reason why it's not easy to "build your own Exalogic": There's a lot of work required to make such a system fly. In fact, anybody who is starting to "just put together a bunch of servers and an InfiniBand network" is really looking at a 6-12 month science project. And the outcome is likely to not be very enterprise-class. And it won't have Exalogic's performance either. Because building an Engineered System is literally rocket science: It takes a lot of time, effort, resources and many iterations of design/test/analyze/fix to build such a system. That's why InfiniBand has been reserved for HPC scientists for such a long time. And only Oracle can bring the power of InfiniBand in an enterprise-class, ready-to use, pre-integrated version to customers, without the develop/integrate/support pain. For more details, check the new Exalogic overview white paper which was updated only recently.

  • Desktop icons disappears when Nautilus is launched, until next boot

    - by Santosh
    What happens: When I log in into my Ubuntu everything is normal, I have some icons on my desktop and I can see them at this point of time. As soon as I click on the explorer (nautilus) on the Launcher bar, everything goes (disappers) and never comes. No matter how many time you click on the launcher, you can't open nautilus. I tried opening nautilus from the terminal, get the following: santosh@santosh:~$ nautilus Initializing nautilus-gdu extension ** (nautilus:2158): DEBUG: SyncDaemon already running, initializing SyncdaemonDaemon object Initializing nautilus-open-terminal extension (nautilus:2158): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed (nautilus:2158): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed Segmentation fault I suspect on "Segmentation fault" on the last line, whats that? I was amazed when I run this command in sudo.: santosh@santosh:~$ sudo nautilus Initializing nautilus-gdu extension ** (nautilus:2216): DEBUG: Syncdaemon not running, waiting for it to start in NameOwnerChanged Initializing nautilus-open-terminal extension (nautilus:2216): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed (nautilus:2216): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares. Error No such file or directory Please ask your system administrator to enable user sharing. As soon as I type sudo nautilus and hit enter, nautilus starts and the desktop background changes (to the default which ubuntu has). Don't know why but at this point as soon as I click on Desktop (from the left pane) then nautilus closes. Did anyone has same issue? I am corrently working with commandline to do my work and its a big pain. Additional Information: Another thing I have noticed that when I want to open the location of PDF file I am reading in document viewer (by clicking the folder icon). It gives error "Could not open the containing folder" and "Failed to execute child process "nautilus" (Permission denied)". Any idea?

  • Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell

    - by SQLOS Team
    Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell Blog This blog post comes from Khalid Mouss, Senior Program Manager in Microsoft SQL Server. Overview The goal of this blog is to demonstrate how we can automate through PowerShell connecting multiple SQL Server deployments in Windows Azure Virtual Machines. We would configure TCP port that we would open (and close) though Windows firewall from a remote PowerShell session to the Virtual Machine (VM). This will demonstrate how to take the advantage of the remote PowerShell support in Windows Azure Virtual Machines to automate the steps required to connect SQL Server in the same cloud service and in different cloud services.  Scenario 1: VMs connected through the same Cloud Service 2 Virtual machines configured in the same cloud service. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually required. Step 1 – Provision VMs and Configure Ports   Provision VM1; named DemoVM1 as follows (see examples screenshots below if using the portal):   Provision VM2 (DemoVM2) with PowerShell Remoting enabled and connected to DemoVM1 above (see examples screenshots below if using the portal): After provisioning of the 2 VMs above, here is the default port configurations for example: Step2 – Verify / Confirm the TCP port used by the database Engine By the default, the port will be configured to be 1433 – this can be changed to a different port number if desired.   1. RDP to each of the VMs created below – this will also ensure the VMs complete SysPrep(ing) and complete configuration 2. Go to SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for <SQL instance> -> TCP/IP - > IP Addresses   3. Confirm the port number used by SQL Server Engine; in this case 1433 4. Update from Windows Authentication to Mixed mode   5.       Restart SQL Server service for the change to take effect 6.       Repeat steps 3., 4., and 5. For the second VM: DemoVM2 Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <username> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) Your will then be prompted to enter the password. Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok. Step 5 – Now connect from DemoVM2 to DB instance in DemoVM1 Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.   Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can longer connect from VM3 remotely to VM1. Scenario 2: VMs provisioned in different Cloud Services 2 Virtual machines configured in different cloud services. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on on-premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually needed. Step 1 – Provision new VM3 Provision VM3; named DemoVM3 as follows (see examples screenshots below if using the portal): After provisioning is complete, here is the default port configurations: Step 2 – Add public port to VM1 connect to from VM3’s DB instance Since VM3 and VM1 are not connected in the same cloud service, we will need to specify the full DNS address while connecting between the machines which includes the public port. We shall add a public port 57000 in this case that is linked to private port 1433 which will be used later to connect to the DB instance. Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <UserName> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) You will then be prompted to enter the password.   Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: Ok. netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok.   Step 5 – Now connect from DemoVM3 to DB instance in DemoVM1 RDP into VM3, launch SSM and Connect to VM1’s DB instance as follows. You must specify the full server name using the DNS address and public port number configured above. Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port   Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.  Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can no longer connect from VM3 remotely to VM1. Conclusion Through the new support for remote PowerShell in Windows Azure Virtual Machines, one can script and automate many Virtual Machine and SQL management tasks. In this blog, we have demonstrated, how to start a remote PowerShell session, re-configure Virtual Machine firewall to allow (or disallow) SQL Server connections.

  • The power of explicit social networks

    - by me
    Last week I had the pleasure to write a guest post on the Oracle WebCenter blog  with the topic The Power of Social Recommendations where I described Implicit and Explicit Social Recommendations models and how they relate to a Social Engagement Strategy. Now let's look at a real live example. Apple has implemented an explicit Social Network model with So what ? Users do this already on Facebook and Twitter!  (see ZDNet blog post : Ping: Apple should leave social to Facebook, Twitter) BUT there are some major  advantages: "100 % control over the explicit Social Network ->  direct customer relationship without a social intermediary like Facebook or Twitter Total  access to the Social Graph ->  own the Social Graph data from their users and no need to "buy" it from external social network providers Integrated into the core business model ->  harvest all Social Graph data  to provide  highly personalized and trusted recommendations Isn't this the dream of any company which thinks about their social media strategy?  and guess what - Oracle Social Network is all about this - building explicit Social Networks with seamless integration into  your core business processes and applications follow me on twitter:  http://twitter.com/peterreiser Enterprise2.0, enterprise2.0, social networks, social media, apple
