• SQL Server 2008 Express + Reporting Services on Windows 7

  - by TimothyP

  I'm trying to install SQL Server Express 2008 and Reporting Services on a x64 Windows 7 Machine for development purposes. I've installed SQL Server 2008 Express with the Microsoft Web Platform Installer I had to manually enable the SQL Server Browser in the Sql Server Configuration Manager and tried to enable the SQL Server Agent but that simply doesn't work. Keeps throwing an RPC error: "The remote procedure call failed. [0x800706be]". The start mode is set to Disabled and I cannot change it. Even though I selected the SQL Server Express with advanced services in the web platform installer I could not find any reference to SQL Server Reporting Services so I used the SQL Server Installation Center x64 application to "upgrade" to SQL Server Express 2008 with advanced services... this installed many things but still I couldn't find any reference to SQL Server Reporting Services other than an application called: "Reporting Services Configuration Manager" This opens up a dialog called "Reporting Services Configuration Connection" which is asking for a server name (shows the name of my machine) and a Find button. When I click the find button I get: "Unable to connect to the Reporting Server WMI provider. Details: Invalid Namespace". I found some references on the web to solve this problem, but they refer to a directory: "%ProgamFiles%\Microsoft SQL Server\MSRS10.SQL2008\Reporting Services\" which does not exist anywhere on my system. (The directories for SQL Server are there, but there is no Reporting Services directory anywhere). What am I doing wrong here? Wasn't the web platform installer supposed to handle all this? Thnx for any advice. PS: Most google results refer to 2005 vs 2008 problems, but I never had 2005 installed on this system, it's a newly installed development machine.

• Disabling standby modus on Gear4 Blackbox speakers

  - by cj

  I have a set of bluetooth Gear4 Blackbox speakers. The sound quality and the design is great, but it switches to standby modus automatically every now and then, when I am listening to music and when it's silent. In that situation, the only way to get them working again is turning them off and on, since they do not react to the remote nor to the buttons on top of it. I emailed Gear4 with this problem and they recommended me to reflash the firmware again, but the problem is persisting after having done that. It has nothing to do with the device that is streaming music. So, the question is, is there a way to disable the standby modus permamently, so the speakers are all the time active even if I am not using them? To switch them off I would just turn the power switch off. If anyone is curious about what device I am talking about, here's a link to Amazon, but I wouldn't reccomend anyone to buy them because of this problem. http://www.amazon.co.uk/Gear-4-PG142-GEAR4-BlackBox/dp/B000QEFZI2 Thanks in advance.

• How to update-grub on a system running overlayroot?

  - by mikepurvis

  We ship boxes configured with overlayroot, using the following overlayroot.conf: overlayroot=device:dev=/dev/sda6,timeout=20,recurse=0 Which produces the following mount configuration: $ mount overlayroot on / type overlayfs (rw,errors=remount-ro) /dev/sda5 on /media/root-ro type ext3 (ro,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered) /dev/sda6 on /media/root-rw type ext3 (rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered) /dev/sda1 on /boot type ext3 (rw) As you can see, three key physical partitions: sda1 is /boot, sda5 is a read-only "factory" root, and sda6 is a "user" root which can be wiped at any point to restore the machine to its original factory state. Now, the problem arises when update-grub is run for any reason: $ sudo update-grub [sudo] password for administrator: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). Understandable, since / is an overlayfs. The contents of /usr/sbin/update-grub are: #!/bin/sh set -e exec grub-mkconfig -o /boot/grub/grub.cfg "$@" With /usr/sbin/grub-mkconfig being the business part of things. But the actual problem is in /usr/sbin/grub-probe, called by grub-mkconfig, and grub-probe is a binary. So my question is, is there a parameter or whatever which can make grub-probe do the right thing in the face of / being an overlayfs? And secondly, is there a way to hack/patch that in so that the update-grub script just does the right thing? Thanks.

• Syncing Music Everywhere with Google Music and iTunes Match - Will This Work?

  - by dragonmantank

  I have the following devices: Personal Laptop running Windows 7/Ubuntu 11.10 (mostly use Ubuntu) Media Server running Windows 7 with PS3 Media Server and iTunes Work Laptop running OSX Snow Leopard iPad iPhone 4S The iPhone just replaced my Droid 2 Global. What I had been doing was using Google Music to watch the folders iTunes was storing music in and moving any new files up to Google Music. The Droid would pull music down from the cloud via streaming or me telling it to make it available offline, I had folders set up with PS3 Media Server to stream them to TV's via DLNA, and used RDP to play music through my speakers in the office. So far it's worked well. Since I've replaced the Droid 2 though with an iPhone, I've lost the syncing ability with Google Music and have to do it via iTunes (I knew this would happen, no big suprise). I got to thinking though - Apple does offer iTunes Match, which allows your devices to stream/download the music from 'the cloud,' much like Google Music. I could then listen to whatever I Wanted (for the most part) on my phone, iPad, and laptops by syncing via iTunes Match. I don't want to loose my MP3s though, and since I've never used iTunes Match, I wonder if the following is a viable solution: Sign up for iTunes Match on my media server Let it scan my library and make available my songs in AAC in the cloud Not delete the media server MP3s Set up other devices to sync to iTunes Match Continue to get MP3s via Amazon or other services and add to iTunes Let the MP3s sync to Google Music, and let the MP3's add to the AAC versions on my devices I think the main kicker is I don't want to lose the MP3 versions of my songs as those will work just fine on all my devices and I generally rip at 320kbps. I don't mind spending $25/year if it means that I can easily shift the music from device to device without much thinking, but I'm not going to pay $25/year to end up converting my library over to AAC just to save myself the hassle of manually syncing my iPad and iPhone.

• Automount in Ubuntu 9.10

  - by easyrider

  Hi, By default Ubuntu doesn't mount internal NTFS hard drives automatically. A fstab solution not working properly, because of conflicts with the "intelligent" mount system. If I add my hd in fstab and reboot - it will be mounted. But if I go to nautilus, open places panel and click eject button (unmount) and than click on hd again to mount it, I will get an error. In 9.04 to solve this problem you need to modify hal rules in /etc/hal/... preferences.fdi in my case I modified it for only one drive. <device> - <match key="storage.hotpluggable" bool="false"> - <match key="storage.removable" bool="false"> <merge key="storage.automount_enabled_hint" type="bool">false</merge> - <match key="storage.model" string="ST3250310NS"> <merge key="storage.automount_enabled_hint" type="bool">true</merge> </match> </match> </match> </device> But this is not working in 9.10 - devs removed this function from hal to devkit-disk or udev? I don't know. Could you please tell me where automount rules are stored in 9.10? And how to create new rules, and what program controls automount in 9.10?

• Sonicwall routing between multiple subnets on multiple interfaces

  - by Rain

  As shown by the network diagram below, I have two completely separate networks. One is being managed by a Sonicwall NSA 220, the other by some other router (the brand is not important). My goal is to allow devices within the 192.168.2.0/24 network to access devices in the 192.168.3.0/24 network. Allowing the reverse (192.168.3.0/24 - 192.168.2.0/24) is not required. So far, I have done the following: I connected the X3 Interface on the Sonicwall to the 192.168.3.0/24 network switch (shown as the dashed red line in the diagram). Next, I gave it a static ip address of 192.168.3.254 and set the Zone to LAN (the same Zone for the X0 interface). Judging by various articles and KBs I've read, this is all that should be necessary, although it does not work. I can ping 192.168.3.254 from any device in the 192.168.2.0/24 network although I cannot ping/connect to any device within the 192.168.3.0/24 network. Any help would be greatly appreciated! Network Diagram: (I asked a similar, yet more complicated, question earlier; although, I realized that I cannot solve that without first solving this (which may actually solve my original question))

• Why does my dd backup of MacBook OS X fail to boot upon restore?

  - by James

  I created a backup of a MacBook hard drive (WD2500BEVS-88US) by hooking it up as a secondary drive on my linux system (Ubuntu 10.10). I used the following command: sudo dd if=/dev/sdc of=/home/backup.img bs=2M This appears to have completed with no errors. I noticed that the file is only 68 GB in size even though the drive is 250 GB in capacity. I restored the image to a spare drive (WD2500BEVS) with the following command: sudo dd if=/home/backup.img of=/dev/sdb bs=2M When I boot the spare drive in the Mac, it appears to start up for a few seconds and then shuts down. (It does not appear to load into the OS at all). When I open up the drive that won't boot in GParted, it looks like this: When looking at the information for the middle partition with the little red exclamation mark, it shows this: The original hard drive that boots ok shows up like this: Further info on both drives: sudo fdisk -l Disk /dev/sdb: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 30402 244198580 ee GPT WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'!

• Boot ISO image from GRUB4DOS on EFI machines

  - by Vladimir Tikhomirov

  I failed with loading ISO image (non-distro) from GRUB2 from USB stick, but found the way how I can boot the GRUB4DOS and then load the image from there. However, it doesn't work all the time and the questions is WHY it doesn't? Environment and loading process: We need to have EFI machine, USB stick, booting ISO, GRUB2 and GRUB4DOS. Last 3 on USB stick. Boot: USB - EFI loader - GRUB2 - GRUB4DOS - ISO image Configuration files To boot GRUB4DOS I use this from grub.cfg: menuentry "image.iso" { linux /syslinux/grub.exe --config-file="/menu.lst" } My menu.lst is here: timeout 20 default 0 title image.iso find --set-root --ignore-floppies --ignore-cd //image.iso map --heads=0 --sectors-per-track=0 //image.iso (hd32) map --hook chainloader (hd32) This works perfectly with Legacy machines. However, when I come to GRUB4DOS, I don't see the menu with image.iso, I see only GRUB command line. That means that my menu.lst didn't load. Why is it like this? Background and ideas I have an idea that GRUB4DOS doesn't recognize my USB stick as a device. I tried the command find and got (hd0,0), (hd0,1), (hd0,2), (rd). When I tried to set root to any of these devices I don't see fat file system, how it was with Legacy machines. The root device is (hd0,0), which has ntfs file system which should be partition with Windows. EFI machines support only GRUB2, so I can't boot GRUB4DOS straight away. Please, don't suggest anything like this, because my image doesn't have kernel. You can imagine that you load HDAT2 or Hiren's boot cd, for example. menuentry "Blancco Blancco5.iso" { set isofile="/image.iso" loopback loop $isofile set root=(loop) linux /isolinux/vmlinuz isofile=$isofile splash quiet initrd /isolinux/initrd }

• Using the RST3 plugin in the Leo Outliner

  - by T-Boy

  I'm currently trying out the Leo Outliner, and I've heard quite a bit about the RST3 plugin that it has. I'm not planning to use Leo to program just yet -- at this point I'm wondering if it might be useful for generating HTML and PDF documents, as I'm quite currently enamored with RST and how it works. I'm using my Ubuntu Netbook Remix netbook (running 9.10, I believe). I think I've got it down pat, more or less -- I've installed docutils using the Synaptics Package Manager, and I think I've gotten SilverCity installed, as per the requirements -- I've downloaded the archive, and then run "sudo python setup.py install" with no errors. The thing is, I'm not exactly sure how to invoke the rst3 plugin itself. It doesn't appear in the Plugins menu for Leo right now, and the documentation I've managed to source doesn't seem to clearly explain how to use the plugin. Has anyone had any experience in using the rst3 plugin in Leo? It's a little confusing right now, and searches on Google doesn't seem to be helping much any more. I'm using the latest 4.7.1 final version of Leo from the Synaptics Package Manager (was informed that this would have offered the best integration with UNR, so I figured, what the heck). Have I missed out on any steps here, and are there any useful tutorials on how to use the rst3 plugin?

• How can I fix my corrupted RAID1 ext4 partition on a Synology DS212 NAS?

  - by Neil

  I have two identical 3 TB disks that were in a RAID1 array, where one disk crashed. I replaced the failed disk, but not after the RAID partitions got messed up. I need to figure out how to restore the RAID array and get at my ext4 partition. Here are the properties of the surviving disk: # fdisk -l /dev/sda fdisk: device has more than 2^32 sectors, can't use all of them Disk /dev/sda: 2199.0 GB, 2199023255040 bytes 255 heads, 63 sectors/track, 267349 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 267350 2147483647+ ee EFI GPT # parted /dev/sda print Model: ATA ST3000DM001-9YN1 (scsi) Disk /dev/sda: 3001GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 131kB 2550MB 2550MB ext4 raid 2 2550MB 4698MB 2147MB linux-swap(v1) raid 5 4840MB 3001GB 2996GB raid I replaced the failed drive, and cloned the surviving drive to it so I have something to work with. I cloned the drives with dd if=/dev/sdb of=/dev/sda conv=noerror bs=64M, and now /dev/sda and /dev/sdb are identical. Here is the RAID information: # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md1 : active raid1 sdb2[1] 2097088 blocks [2/1] [_U] md0 : active raid1 sdb1[1] 2490176 blocks [2/1] [_U] unused devices: <none> It seems that md2 is missing.

• How to stop Excel 2003 from loading a Gazillion files

  - by Gary M. Mugford

  One of my soon-to-be-ex-friends got an Excel file from another friend of his and decided to click on it. It started opening all kinds of files from within Excel. Over 200 and still counting when he called me. I told him to go to task manager, which showed a LOT of files in the applications tab, but only one Excel.exe in the processes tab. Closing it down there, closed down Excel. I then CrossLooped in to see if I could give him a helping hand. Each time Excel was re-opened, the mass influx of files started. They were all kinds of files, PDFs, Docs, JPGs, even some spreadsheets. It looked like the end of solitaire, with multiple windows opening (XP) and the counter on the lone Excel button on the task bar counting off the files. I did the task manager exit routine and went looking for temp files. I CrapCleaned out the system. Made sure I went through the files created in the last hour and deleted anything with a temp anywhere in it. I also deleted the crappy infected/corrupted file from it's place on the desktop (yeah, I know, I yelled for 15 minutes on THAT subject). Despite a delousing, the restart of Excel, which complained of a deactivated add-in, would start the cascading windows, whether I answered yes or no to that question. Yes, it knew it had a serious crash, but why would it just keep on trying to load the bad file, even when I got rid of it? But here's the real question. WHERE was it loading from? I went through the backup folder and NOTHING was there! So what's the process for starting Excel WITHOUT it trying to do a crash recovery? Sort of makes me feel stupid at times. Thanks for any light you can shed on this issue. GM

• Grant access for users on a separate domain to SharePoint

  - by Geo Ego

  Hello. I just completed development of a SharePoint site on a virtual server and am currently in the process of granting users from a different domain to the site. The SharePoint domain is SHAREPOINT, and the domain with the users I want to give access to is COMPANY. I have provided them with a link to the site and added them as users via SharePoint, which is all I thought I would need to do. However, when they go to the link, the site shows them a SharePoint error page.

• kvm works only when kvm-intel is unloaded

  - by Sathya

  I am new to kvm. I have this strange issue. But before explaining the issue, here is my set up. I try to install VM on my Host which is a Acer Laptop 5720 Has T7500 Intel processor. The cpu flags indicate that Virtualization is supported. I run Ubuntu 10.04 (lucid) on it. It comes with kvm. Now coming to the issue - I dont get any errors while executing "sudo modprobe kvm-intel". So I presume my processor does indeed support hardware virtualization. I use virt-manager and create a VM on which I install ubuntu from an *.iso file. When I start the VM it says it is running. No signs of any trouble. I can see the domain list in "virsh list". But when I try to connect to the VM thru VNC, all I get to see is a blank screen (no cursor). There is no response to any key press. I changed the video mode etc. Tried all different combinations but none work. But strangely, if I shutdown the vm an virt-manager and then unload the module by doing "sudo modprove -r kvm-intel", everything works fine. ie., I can see the screen via VNC. I am able to install the OS and so on. So what does this mean ? IS hardware virtualization not supported ? How come there is no error anywhere ? dmesg | grep kvm doesnt report anything. Can someone throw light on what excatly is happening ?

• SQL Server Management Studio not scripting all objects

  - by Ian Boyd

  i've been attempting to script a database using SQL Server 2005 Management Studio. i cannot get it to script some objects. It scripts others, but skips some. i can provide detailed screen shots the options being selected including all tables the folder where the script files will go the folder being empty before scripting the scripting process saying Sucess when scripting a table the destination folder no longer empty, with a hundred or so script files the script of some tables not being in the folder. And earlier SSMS would not script some views. Is this a known thing that the the Generate Scripts task does not generate scripts? Update Known issue on Microsoft Connect, but Microsoft couldn't repro the steps, so they closed closed the ticket. Fails on SQL Server 2005, also fails on SQL Server 2008.

• Problem setting command-line console resolution. vbeinfo in grub2 does not report all resolutions

  - by Kent

  I have a Asus EEE PC 1005P which I installed a Command-line system on using the Alternate Installer CD of Ubuntu Lucid Lynx. Altough I think this is a general linux and grub2 question. I do not have (or want) the X Window System installed. I want to change my console screen resolution (not inside X) to 1024x600. But it isn't reported when I use vbeinfo inside grub: grub> vbeinfo VBE info: version: 3.0 OEM software rev: 1.0 total memory: 8128 KiB List of compatible video modes: Legend: P=Packed pixel, D=Direct color, mask/pos=R/G/B/reserved 0x112: 640 x 480 x 32 Direct, mask: 8/8/8/8 pos: 16/8/0/24 0x114: 800 x 600 x 16 Direct, mask: 5/6/5/0 pos: 11/5/0/0 0x115: 800 x 600 x 32 Direct, mask: 8/8/8/8 pos: 16/8/0/24 0x101: 640 x 480 x 8 Packed 0x103: 800 x 600 x 8 Packed 0x111: 640 x 480 x 16 Direct, mask: 5/6/5/0 pos: 11/5/0/0 Configured VBE mode (vbe_mode) = ox101 grub> Relevant parts of sudo lspci -v: ... ... 00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller Subsystem: ASUSTeK Computer Inc.

• Experience with AMCC 3ware 9650se raid cards? Ours seems dead

  - by antiduh

  We have a 8-port 3ware 9650se raid card for our main disk array. We had to bring the server down for a pending power outage, and when we turned the machine back on, the raid card never started. This card has been in service for a couple years without problems, and was working up until the shutdown. Now, when we turn the machine on, the bios option rom that normally kicks in before the bootloader doesn't show up, none of the drives start, and when the OS tries to access the device, it just times out. The firmware on it has been upgraded in the past, so it's possible we've hit some sort of firmware bug. We're using it in a Silicon Mechanics R272 machine with gentoo for the OS. The OS eventually boots, but alas, without the card. We've ordered a new one, but I'm worried that if we replace the card it won't recognize the existing array. Has anybody performed a card swap before? Any help would be greatly appreciated. Edit: These are the kernel errors we see: 3ware 9000 Storage Controller device driver for Linux v2.26.02.012. 3w-9xxx 0000:09:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 3w-9xxx 0000:09:00.0: setting latency timer to 64 3w-9xxx: scsi0: ERROR: (0x06:0x000D): PCI Abort: clearing. 3w-9xxx: scsi0: ERROR: (0x06:0x001F): Microcontroller not ready during reset sequence. 3w-9xxx: scsi0: ERROR: (0x06:0x0036): Response queue (large) empty failed during reset sequence. 3w-9xxx 0000:09:00.0: PCI INT A disabled

• Where should CentOS users get /usr/share/virtio-win/drivers for virt-v2v?

  - by Philip Durbin

  I need to migrate a number of virtual machines from VMware ESX to CentOS 6 KVM hypervisors. Ultimately, I wrote an RPM spec file that solved my problem at https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec but I'm not sure if there's another RPM in base CentOS or EPEL (something standard) I should be using instead. Originally, I was getting this "No root device found in this operating system image" error when attemting to migrate a Window 2008 VM. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm virt-v2v: No root device found in this operating system image. . . . but I solved this with a simply yum install libguestfs-winsupport since the docs say: If you attempt to convert a virtual machine using NTFS without the libguestfs-winsupport package installed, the conversion will fail. Next I got an error about missing drivers for Windows 2008. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/amd64/Win2008 . . . and I resolved this by grabbing an iso from Fedora at http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ as recommended by http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers and building an RPM from it with this spec file: https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec Now, virt-v2v exits without error: [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: my-vm configured with virtio drivers. [root@kvm01b ~]# Now, my question is, rather that the virtio-win RPM from the spec file I wrote, is there some other more standard RPM in base CentOS or EPEL that will resolve the error above? Here's a bit more detail about my setup: [root@kvm01b ~]# cat /etc/redhat-release CentOS release 6.2 (Final) [root@kvm01b ~]# rpm -q virt-v2v virt-v2v-0.8.3-5.el6.x86_64 See also Bug 605334 – VirtIO driver for windows does not show specific OS: Windows 7, Windows 2003

• Can I change the user id of a user on one Linux server to match another server in /etc/passwd?

  - by user76177

  I have a Rails application that is on a virtual machine (RHEL 6) and it's database is on dedicated hardware (also RHEL 6). The app server has an NFS directory from the db server mounted and accessible. It needs to write images to that server that are uploaded via the app. Background processes on the db server need to read and write to the same directory, as they perform resizing operations on the uploaded files. Right now none of this is working, because the user ids are different between the two systems. I only need this to work for this one application, so it is way too much overhead to put an LDAP system in place. Can I simply change the user id of this one user in one of the systems, or will that cause mass chaos? UPDATE: The fix worked, at least on local devices. Unfortunately the device I have mounted to the main db server still thinks my user id is 502 instead of 506. Do I need to remount that device, or is there an NFS daemon I can stop and restart to refresh it?

• P2v options within a hyper-v environment.

  - by tony roth

  I have a server that san boots that I want to p2v. I have many options disk2vhd, scvmm etc but I was thinking about cloning the lun (flexclone, netapp) presenting it to my hyper-v r2 server. Within the hv manager do a create new disk then have it copy the cloned lun to a vhd file. Then do the bcdedit\bootsect stuff to it. Should work right? I'm also curious if anybodys booting vhd's that are on bootable luns? I've booted native vhd's just fine was just curious about the running them off a bootable lun. I think that this has quite a few advantages like instant p2v etc.. any thoughts on this? hmm dang as I was typing this I realized that I should not use the hv manager new disk copy routine, I should just disk2vhd the mounted lun. This has advantages in that it should be a lot faster!! discovered that disk2vhd may be flaky, crashed the first time I ran it! thanks

• High mysql server load, sar output

  - by eric

  I have a MySQL Server that should be performing better than it seems to be. We're running ubuntu on a Amazon Cluster Compute (cc1.4xlarge) Linux ip-10-0-1-60 3.2.0-25-virtual #40-Ubuntu SMP Wed May 23 22:20:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Distributor ID: Ubuntu Description: Ubuntu 12.04 LTS Release: 12.04 Codename: precise I have several output files from sar that i'm not really sure how to interpret. For example, I ran: # Individual block device I/O activities sar -d 1 180 > logs/block_device_io.log & which gave me what looks like really high utilisation of my disk (turns out this block device maps to /dev/xvdh on /var/lib/mysql type ext4 (rw,_netdev) The output from my log: 10:48:59 PM DEV tps rd_sec/s wr_sec/s avgrq-sz avgqu-sz await svctm %util 10:49:00 PM dev202-16 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:49:00 PM dev202-32 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:49:00 PM dev8-0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:49:00 PM dev202-112 1008.00 31040.00 1416.00 32.20 1.02 1.01 0.89 90.00 10:49:00 PM dev202-80 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 Am I wrong in thinking this is a problem?

• Oracle with Kerberos authentication and Windows 2003 Server as KDC

  - by Supaplex

  I am running Oracle 10.2 on a Windows 2003 Server SP2 which is also the domain controller on the network. I wish to switch authentication method from NTS to Kerberos. I have spent a lot of time trying to configure Oracle with Kerberos authentication from the Oracle Advanced Security option from the Net Manager utility. I have disabled NTS so Kerberos is promoted as the preferred authentication method. But as soon as the configuration is saved from Net Manager and I restart the Oracle server service, Oracle will not start. I don't know what Oracle is complaining about, because I don't know where to look for the Oracle error log. My first question is: how can I figure out what's bugging Oracle? My second question: is there a good tutorial for setting up Oracle on a Windows 2003 with Kerberos Authentication, where the Windows 2003 Server is the KDC? Maybe there is a book I can get? I have read Oracles own guide, but it is mostly for Linux/Unix. Thanks a lot!

• Windows Server 2008 R2 SP1 Drivers Missing Would Not Install?

  - by bleepzter

  I am building my dev machine with WS2008R2SP1. I consider Windows Server as the best development environment for C# since I tend to focus on server-centric (integration) applications. The desktop flavor of Windows (7) doesn't play nicely with things like Commerce Server or BizTalk... so I to like stick to the environment I develop for. Previously I used to develop inside of VM's but I've found that it is super inefficient and tends to take a toll on the laptops. (I've gone through two of them in 6 months). Problem is that I multiple devices that do not want to be recognized by Windows: My machine is Dell Precision M4500: Intel Core i7-Q740, 1TB HDD, 8GB RAM, Dell re-branded Broadcom DW1501 802x11n Half-Mini Card, Dell re-branded Broadcom DW375 Bluetooh Module, Intel 82577LM Gigabit Network connection NVidia Quadro FX1800 Graphics The devices in question are the Dell rebranded broadcom network and bluetooth adapters: Broadcom USH: USB\VID_0A5C&PID_5800&REV_0101&MI_00 USB\VID_0A5C&PID_5800&MI_00 DW375 Bluetooth Module USB\VID_413C&PID_8187&REV_0517 USB\VID_413C&PID_8187 When I ran the broadcom installers I get "Operating System not supported" which I think is a big oversight on Broadcom's part. Why check for system version string? UGHGHGH Moreover if I try to manually force the driver in windows... I get an error: Driver Management concluded the process to install driver FileRepository\btwampsecfl.inf_amd64_neutral_d8fc2b85d035ed47\btwampsecfl.inf for Device Instance ID USB\VID_0A5C&PID_5800&MI_00\7&66DE6C9&0&0000 with the following status: 0xe0000217. '- or - Driver Management concluded the process to install driver FileRepository\btwampfl.inf_amd64_neutral_d4c4acf036c61299\btwampfl.inf for Device Instance ID USB\VID_413C&PID_8187\90004EEEF5A6 with the following status: 0xe0000217. I googled the 0xe0000217 error code and it says Bad service install section in the driver inf file... Any ideas on how to fix this? I also tried the post by BetaIQ on MSDN Forum, unfortunately the links to the driver package included in the post were dead :( PS. On a side note I also do mobile development for Android, iOS, and Windows Phone, and BB. Having the bluetooth is quite useful with mobile devices.
