  • Verizon Wireless Supports its Mission-Critical Employee Portal with MySQL

Verizon Wireless built the first wide-area wireless broadband network and delivered the first wireless consumer 3G multimedia service in the US, and offers global voice and data services in more than 200 destinations around the world. To support 4.2 million daily wireless transactions and 493,000 calls and emails transactions produced by 94.2 million retail customers, Verizon Wireless employs over 78,000 employees with area headquarters across the United States. The Business Challenge Seeing the stupendous rise in social media, video streaming, live broadcasting…etc which redefined the scope of technology, Verizon Wireless, as a technology savvy company, wanted to provide a platform to its employees where they could network socially, view and host microsites, stream live videos, blog and provide the latest news. The IT team at Verizon Wireless had abundant experience with various technology platforms to support the huge number of applications in the company. However, open-source products weren’t yet widely used in the organization and the team had the ambition to adopt such technologies and see if the architecture could meet Verizon Wireless’ rigid requirements. After evaluating a few solutions, the IT team decided to use the LAMP stack for Vzweb, its mission-critical, 24x7 employee portal, with Drupal as the front end and MySQL on Linux as the backend, and for a few other internal websites also on MySQL. The MySQL Solution Verizon Wireless started to support its employee portal, Vzweb, its online streaming website, Vztube, and internal wiki pages, Vzwiki, with MySQL 5.1 in 2010. Vzweb is the main internal communication channel for Verizon Wireless, while Vztube hosts important company-wide webcasts regularly for executive-level announcements, so both channels have to be live and accessible all the time for its 78,000 employees across the United States. However during the initial deployment of the MySQL based Intranet, the application experienced performance issues. High connection spikes occurred causing slow user response time, and the IT team applied workarounds to continue the service. A number of key performance indexes (KPI) for the infrastructure were identified and the operational framework redesigned to support a more robust website and conform to the 99.985% uptime SLA (Service-Level Agreement). The MySQL DBA team made a series of upgrades in MySQL: Step 1: Moved from MyISAM to InnoDB storage engine in 2010 Step 2: Upgraded to the latest MySQL 5.1.54 release in 2010 Step 3: Upgraded from MySQL 5.1 to the latest GA release MySQL 5.5 in 2011, and leveraging MySQL Thread Pool as part of MySQL Enterprise Edition to scale better After making those changes, the team saw a much better response time during high concurrency use cases, and achieved an amazing performance improvement of 1400%! In January 2011, Verizon CEO, Ivan Seidenberg, announced the iPhone launch during the opening keynote at Consumer Electronic Show (CES) in Las Vegas, and that presentation was streamed live to its 78,000 employees. The event was broadcasted flawlessly with MySQL as the database. Later in 2011, Hurricane Irene attacked the East Coast of United States and caused major life and financial damages. During the hurricane, the team directed more traffic to its west coast data center to avoid potential infrastructure damage in the East Coast. Such transition was executed smoothly and even though the geographical distance became longer for the East Coast users, there was no impact in the performance of Vzweb and Vztube, and the SLA goal was achieved. “MySQL is the key component of Verizon Wireless’ mission-critical employee portal application,” said Shivinder Singh, senior DBA at Verizon Wireless. “We achieved 1400% performance improvement by moving from the MyISAM storage engine to InnoDB, upgrading to the latest GA release MySQL 5.5, and using the MySQL Thread Pool to support high concurrent user connections. MySQL has become part of our IT infrastructure, on which potentially more future applications will be built.” To learn more about MySQL Enterprise Edition, Get our Product Guide.

  • How do I fix this Windows 7 wireless connectivity issue?

    - by Charles Randall
    I have a laptop with an Intel Wireless Centrino 6300 module. Recently, the machine has stopped properly connecting to my wireless router. It will get stuck in a loop of connecting, then disconnecting and reconnecting. While connected, it will simply say "No Internet Access." Running inSSIDer 2.0, it shows my network jumping around between two channels -- I know this isn't the case, because I've set my router to sit on one single channel. My MacBook Pro, Boxee Box, PS3, and Xbox 360 all connect fine to the wireless and have no problems at all. I know it's not the wireless module, as I bought a second one recently assuming the first had died -- but I get the same behavior with both. Sometimes, I can fix the issue temporarily by deleting the network (Using the Manage Wireless Networks page), and then re-adding it (via standard wireless methods). Then it will work for a few days. But inevitably the problem comes back, and now the laptop simply won't connect to the wireless at all, even if I take steps that usually work. Since I've ruled out the hardware, and it's unlikely some kind of interference issue (because I would expect to see it on any multitude of other devices), I would think at this point that it's a problem with Windows itself. One thing that might be a hint, even though I delete the network, when I add it again, it's always listed as "Wireless Network Connection 2" even though there isn't another in the list.

  • iwlwifi on lenovo z570 disabled by hardware switch

    - by Kevin Gallagher
    It was working fine with windows 7. The hardware switch is not disabled. I've toggled it back and forth dozens of times. The wifi light never turns on and it always lists as hardware disabled. I have the latest updates installed. I've been searching for solutions, but none of them seem to work for me. I've tried removing acer-wmi. I've tried setting 11n_disable=1. I've tried resetting the bios. I've tried using rfkill to unblock (only removes soft block). I've rebooted dozens of times. The wifi light turns off as soon as grub loads. Edit: I have a usb edimax wireless nic. It shows hardware disabled as well (although rfkill lists as unblocked). If I unload iwlwifi the usb nic works fine. uname -a `Linux xxx-Ideapad-Z570 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linu`x rfkill list 19: phy18: Wireless LAN Soft blocked: no Hard blocked: yes dmesg [43463.022996] Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: [43463.023002] Copyright(c) 2003-2011 Intel Corporation [43463.023107] iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [43463.023190] iwlwifi 0000:03:00.0: setting latency timer to 64 [43463.023253] iwlwifi 0000:03:00.0: pci_resource_len = 0x00002000 [43463.023257] iwlwifi 0000:03:00.0: pci_resource_base = ffffc900057c8000 [43463.023261] iwlwifi 0000:03:00.0: HW Revision ID = 0x0 [43463.023797] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X [43463.024013] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Wireless-N 1000 BGN, REV=0x6C [43463.024250] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [43463.045496] iwlwifi 0000:03:00.0: device EEPROM VER=0x15d, CALIB=0x6 [43463.045501] iwlwifi 0000:03:00.0: Device SKU: 0X50 [43463.045504] iwlwifi 0000:03:00.0: Valid Tx ant: 0X1, Valid Rx ant: 0X3 [43463.045542] iwlwifi 0000:03:00.0: Tunable channels: 13 802.11bg, 0 802.11a channels [43463.045744] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

  • What's the difference between a wifi access point and station?

    - by Earlz
    I noticed that my (rooted) modem has some hidden modes for wifi. It has the default(and only setting without rooting) wireless access point, but it also has the settings repeater, ad-hoc, and station. What I'm really curious about is this station mode and how it differs from access point. I did a cursory search and didn't come up with any significant differences, other than that they are two distinct modes on many wireless chipsets. What is this station mode and how does it differ from access point?

  • Huawei HG8245T Router - not connecting to another router

    - by BubbaK
    I just got a fiber optic connection installed at home and due to the build of the house, it's mostly cement/bricks, the wireless connection isn't received throughout the house. Previously, to combat this issue, I just ran a hardwire from the modem downstairs and upstairs and had it connected to a secondary (DLink) router. It did the job of getting me seamless wireless internet access everywhere. The issue is now with the new Huawei router, this setup isn't working. I have connected everything as previously, but it seems that the other (DLink) routers are not picking up the connection. I have tried everything and am totally lost as what to do to overcome this problem. Any help would be appreciated.

  • Block access to certain websites from other computers on shared internet connection

    - by Dheeraj V.S.
    I have very little knowledge about networking. I have an internet connection on my PC (running Windows XP). I've enabled internet connection sharing to other computers on my network connected using a WIFI router. I want to block use of GMail (in general, specific domains) from other computers, but should be able to access them from my own machine. I can't edit my hosts file because my machine too would lose access. I guess I need to configure my wireless router for that. But I have no idea how to do so. My wireless router is a Zyxel P-660HW-T1 v2. I'd appreciate any pointers.

  • Bridging a non-persistent PPP connection to wireless (or wired) in Windows XP

    - by phooze
    I have a 3G modem-like device (eMobile's D01NX, PC card style, for any Japan nerds out there) that I use to connect my PC to the Internet. I'd like to bridge this connection with another computer either via an ad-hoc wireless network, or a simple cross-over cable (either are options). However, when I open "Network Connections", I do not see the PPP connection (otherwise I could click both and bridge). I believe this is because there is software (provided by the vendor) that is handling the card directly and registering a PPP connection dynamically. When connected, an ipconfig at the command line yields: Ethernet adapter wireless: Connection-specific DNS Suffix . : Autoconfiguration IP Address. . . : 169.254.5.169 Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : Ethernet adapter lan: Media State . . . . . . . . . . . : Media disconnected PPP adapter {B59EEDDE-A22B-48DF-93E5-04842B641257}: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 114.xx.xxx.xx Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 114.xx.xxx.xx (I've commented out my IP address for privacy reasons, but what does appear there is a functional Internet IP address.) When I disconnect the adapter with the vendor software, the PPP connection disappears completely from the ipconfig list. Any ideas on how to do this?

  • Can't ping other machines in my network

    - by judahgabriel
    I've got 3 machines on my network, all running Windows 7. None of them can ping each other, can't see each other on the network, can't see shares, can't remote desktop, can't see any homegroups. They are all on the same workgroup. They are all connected to the same wireless, WPA2 secured network. They all worked together nicely until I added a password to my wireless network. After that, and after reconnecting all the machines to the password-protected network, they can't see each other. Any ideas what could be wrong?

  • My Router is fast when i reset it but slows down seconds later

    - by hglocke
    I have a Belkin N wireless router which until recently worked perfectly fine. Now i have to reset the router every few minutes, otherwise it slows down to a crawl. What can I do? I have tried turning the routers firewall off, but it does not make any difference. As far as I'm aware there have been no recent firmware updates. EDIT: The other devices on my network (laptop and iphone) do not have this problem. I connect to the router using a TP-Link wireless network card and I have already tried uninstalling and installing the driver. Hopefully this will narrow down the problem significantly.

  • Yoga Pro 2 Wi-Fi not working

    - by user293004
    I installed Ubuntu 14.04 on my new Yoga Pro 2 and the wireless is not working. It started with Windows 8 on it. The Network Manager says Wi-Fi is disabled by hardware switch. I tried putting a blacklist file in ect/modprobe.d as has been suggested in many places. I called the file "blacklist-ideapad_laptop.conf" and wrote in the file blacklist ideapad_laptop I checked to make sure that the wireless is enabled in the BIOS. It is. I ran rfkill list all and it displayed: 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: yes I ran iwlist wlan0 scan and it displayed: wlan0 Failed to read scan data : Network is down I ran sudo rmmod ideapad_laptop and it displayed: rmmod: ERROR: Module ideapad_laptop is not currently loaded. I ran ifconfig wlp1s0 up and it displayed: wlp1s0: ERROR while getting interface flags: No such device. I ran "lspci" and it displayed: 01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b) I ran sudo lshw -c network and it displayed: *-network DISABLED description: Wireless interface product: Wireless 7260 vendor: Intel Corporation physical id: 0<br> bus info: pci@0000:01:00:0.0 logical name: wlan0 version: 6b serial: 7c:7a:91:5f:9b:fa width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.13.0-24-generic firmware=22.24.8.0 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:61 memory:b0400000-b0401fff This No wireless with Intel Centrino Advanced-N 7260 seems to be dealing with a similar issue.

  • How to specify Wireless or Bluetooth in GameKit when using my own custom interface

    - by DonnaLea
    Hi, I've decided to implement my own interface for connecting two devices running my game, as opposed to using the GKPeerPickerController. This is actually working quite well. But I just realised that in my creating of the GKSession I'm not actually specifying whether the connection should be Wireless or Bluetooth. I have an option in my interface to let the user specify which connection method they'd like to use. How do I tell GKSession whether I want it to connect via Bluetooth or Wireless? I think what is currently happening is that it defaults to Wireless if wireless is enabled otherwise it uses Bluetooth. But I'd like to let the user specify which connection method, is this possible? Thanks, Donna

  • Wireless Network Disappearing From Available Networks (Windows 7)

    - by PeteDaMeat
    I have been using Windows 7 with a BT Voyager wireless adapter to connect to my home wireless network for around the last 6 months or so and until recently have experienced no problems. However, over the last couple of days Windows has been unable to connect to the network and the network name is no longer visible in the list of available wireless networks. The only way I have got round the problem is to reboot the NetGear router and to change the SSID to a network name which has not already been used. I do not believe the problem is with the router as my mobile phone can connect to it without any problems. The BT Voyager wireless adapter detects all other available networks so I presume this is a Windows 7 issue as it seems to occur when the PC is rebooted. This problen has happened twice in the last 2 days and is becoming extremely annoying. Does anyone have any suggestions?

  • Wireless AP Placement and Digramming

    - by Matt Simmons
    I'm trying to research the best placement of wireless APs in a given space, and I'm running into problems in gathering information. I found (what I thought was) a great source in this tech republic article: http://techrepublic.com.com/5206-6230-0.html?forumID=82&threadID=163120 While this diagram seems detailed and overall very informative, there were a lot of comments talking about how it was lacking in things like "wire racks, microwaves, concrete walls, motors..." etc. Maybe I'm rash, but I just sort of looked around my office (which is, albeit, somewhat smaller than the one diagrammed), and went "uhhh, there", and hooked up the AP. It seems to cover everywhere. I imagine if my office quadrupled in size, I'd logically divide it up and put four APs in, with a similar amount of thought devoted to each. So, suppose I had a much more complex office. What tools (both diagramming and surveying) do you use to plan your AP placement?

    I am trying to set up a home network. I live in a location without cable internet so I have a Verizon MiFi card. I have a few laptops at the moment and they each connect through the card but I want to set up an Ubuntu 10.10 server and see if I can use it for DHCP. I have a Trendnet TEG-S50G switch and the computer I plan to use for the server has a Linksys WMP-11 Wireless PCI card. Is there any other equipment I need in order to get this to work? Is this even doable? Is there a better way to make this happen?

I work in a lab environment where I need to use the Ethernet Port as a Static IP to interact with a local network (which cannot talk to the outside world). What I would like to do is use the Wireless as the internet connection so i can check email, etc at the same time I am using the ethernet network... It seems like this is not possible. Is there a piece of software or a way to configure it to allow me to do this?

  • Packet loss with Broadcom wireless and Ubuntu

    - by stevemegson
    I have a machine with Ubuntu 9.04 and a Broadcom BCM4306 wireless card which has been running quite happily for many months with the b43legacy driver that's suggested by Hardware Drivers. Suddenly, I'm now seeing crippling packet loss, varying between 30% and 90% when pinging the router. My WinXP machine is still quite happy even when sat next to the Ubuntu box, so I assume that it's not some new source of interference. What else is likely to have changed? How should I go about diagnosing and fixing this?

  • Setting up a wireless access point with Ubuntu server

    - by Solignis
    I am trying to setup a wifi access point with my Ubuntu server, everything "seems" to be good since I got a better wifi radio (long story). But now I am a little confused, when my Android phone tries to associate with the AP it is able to with no problem but then it cannot get an IP address from my DHCP server. I have tried messing with firewall rules, nothing... I tried making a bridge interface as per what I am told I had to do. ( Not sure if i did it right though). What I am trying to do if make the wireless interface an extention of my eth0 network. Am I on the right track or am I going about the wrong way?
