  • INFORMIX - listener thread err 25582

    - by Samuel Lao
    I´ve been digging different forums in the last 7 days looking for a possible solution.... Our database is based on informix running in a Linux server (LINUX SUSE 11). Suddenly, last saturday informix began to show an error message: listener-thread err=-25582 oserr=0, network connection is broken End users started to call reporting about slow network performance to this server, moments where the database application lost connection with server...so we proceeded doing a ping to the db server, getting good responses (1ms) without losing packets. I tried typing telnet (ipserver) 1526 which is informix's port for the application, it works. We had to disconnect the server and enable a backup db server which is located on another branch. It has been working in a regular way because the backup server hasn´t good specs (it is an old dell server model). So, I scanned the main server looking for viruses using Trend Micro Server Protect, it didn´t find anything (0 viruses and spywares). I revised the switches and routers, but I haven´t find anything strange... What else could be ? Thanks in advanced for your time and help with this issue.....I would really appreciate any advice...

  • Bacula & Multiple Tape Devices, and so on

    - by Tom O'Connor
    Bacula won't make use of 2 tape devices simultaneously. (Search for #-#-# for the TL;DR) A little background, perhaps. In the process of trying to get a decent working backup solution (backing up 20TB ain't cheap, or easy) at $dayjob, we bought a bunch of things to make it work. Firstly, there's a Spectra Logic T50e autochanger, 40 slots of LTO5 goodness, and that robot's got a pair of IBM HH5 Ultrium LTO5 drives, connected via FibreChannel Arbitrated Loop to our backup server. There's the backup server.. A Dell R715 with 2x 16 core AMD 62xx CPUs, and 32GB of RAM. Yummy. That server's got 2 Emulex FCe-12000E cards, and an Intel X520-SR dual port 10GE NIC. We were also sold Commvault Backup (non-NDMP). Here's where it gets really complicated. Spectra Logic and Commvault both sent respective engineers, who set up the library and the software. Commvault was running fine, in so far as the controller was working fine. The Dell server has Ubuntu 12.04 server, and runs the MediaAgent for CommVault, and mounts our BlueArc NAS as NFS to a few mountpoints, like /home, and some stuff in /mnt. When backing up from the NFS mountpoints, we were seeing ~= 290GB/hr throughput. That's CRAP, considering we've got 20-odd TB to get through, in a <48 hour backup window. The rated maximum on the BlueArc is 700MB/s (2460GB/hr), the rated maximum write speed on the tape devices is 140MB/s, per drive, so that's 492GB/hr (or double it, for the total throughput). So, the next step was to benchmark NFS performance with IOzone, and it turns out that we get epic write performance (across 20 threads), and it's like 1.5-2.5TB/hr write, but read performance is fecking hopeless. I couldn't ever get higher than 343GB/hr maximum. So let's assume that the 343GB/hr is a theoretical maximum for read performance on the NAS, then we should in theory be able to get that performance out of a) CommVault, and b) any other backup agent. Not the case. Commvault seems to only ever give me 200-250GB/hr throughput, and out of experimentation, I installed Bacula to see what the state of play there is. If, for example, Bacula gave consistently better performance and speeds than Commvault, then we'd be able to say "**$.$ Refunds Plz $.$**" #-#-# Alas, I found a different problem with Bacula. Commvault seems pretty happy to read from one part of the mountpoint with one thread, and stream that to a Tape device, whilst reading from some other directory with the other thread, and writing to the 2nd drive in the autochanger. I can't for the life of me get Bacula to mount and write to two tape drives simultaneously. Things I've tried: Setting Maximum Concurrent Jobs = 20 in the Director, File and Storage Daemons Setting Prefer Mounted Volumes = no in the Job Definition Setting multiple devices in the Autochanger resource. Documentation seems to be very single-drive centric, and we feel a little like we've strapped a rocket to a hamster, with this one. The majority of example Bacula configurations are for DDS4 drives, manual tape swapping, and FreeBSD or IRIX systems. I should probably add that I'm not too bothered if this isn't possible, but I'd be surprised. I basically want to use Bacula as proof to stick it to the software vendors that they're overpriced ;) I read somewhere that @KyleBrandt has done something similar with a modern Tape solution..

  • Why would Windows use slower network interface despite route metrics?

    - by tim11g
    On my previous notebook, the Dell/Broadcom wireless adapter had an option to automatically disable wireless when a wired network is connected, so I never dealt with multiple active interfaces. My current system has an Intel wireless adapter, and they apparently haven't figured out how to turn it off when there is a wired connection. Unless I explicitly remember to disable wireless when docked, the connection is active. That shouldn't be a problem (in theory), since the route metric will cause traffic to go over the fastest network (as indicated by the lowest metric in the routing table). Apparently not - I'm running a backup and seeing the throughput at 25Mbps or so (which is consistent with 802.11g) when a perfectly good Gigabit Ethernet interface is also connected. IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.104 10 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.109 25 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 Windows has correctly identified the Ethernet interface (.104) and assigned it the lower (preferred) metric. So the Ethernet interface should be used exclusively, right? Why is the Ethernet connection not being used? What other factors are involved? (This is with Windows 7 if it makes a difference)

  • Centralized Windows/Mac Patch Management that is easy to use

    - by BiggsTRC
    I'm looking for advice on what patch management solutions you would recommend based upon your experience. I'm also looking for which ones you would not recommend based upon your experience. We have a mixed network of Windows and Mac clients. Our central servers are all Windows servers, although I have considered putting in a Mac server to better handle our Mac clients. The issue we are facing currently is that we need to maintain the patches on all of our third-party applications. Right now we use WSUS, which handles with patching of Windows and some Microsoft products but that is about it. I need something to cover the other applications, specifically things like Adobe products (Reader, Flash, Dreamweaver, etc.) Our network isn't that big (maybe 200 clients) and I don't have a person to dedicate just to patching and maintaining a patch management solution. Thus very large and complicated solutions like System Center are most likely out. I have recently been looking at Dell's Kace K1000 solution (http://www.kace.com/products/systems-management-appliance/). It seems simple and it provides a lot of tools in one package that I would like/need as well. I like the fact that it is self-contained in an appliance and that it is designed for solutions like mine. However, I'm not sure if this is the best solution. I've also looked some at Shavlik's Netchk solution (http://www.shavlik.com/netchk-protect.aspx) but I don't need an anti-virus product. However, it looks like they might have a very good patch database. My question is this: What are your thoughts on these to products? Are there better products out there? Are there issues that I'm not considering? I want something that is very good at patching a broad range of products, that is simple to use, that takes a minimal amount of management (like WSUS), and that (hopefully) works with Mac and Windows.

  • Monitor connected with WiDi just shows a black screen

    - by Pops
    I have a Dell XPS 18 and want to use an external monitor with it. The monitor has VGA and DVI-D inputs. The XPS 18 has no video output ports, but it does support Intel WiDi. I have a Netgear P2TV2000 WiDi receiver, but it only has composite and HDMI outputs. I'm connecting the receiver to the monitor with an HDMI cable and an HDMI/DVI-D adapter. So, in short, the video path is: Computer → WiDi → WiDi receiver → HDMI cable → HDMI/DVI-D adapter → Monitor After setting all this up, I can't get anything to display on the monitor. At the moment I power the monitor on, I can see my desktop for a brief fraction of a second, and then everything goes black. All of the relevant drivers have been updated to the latest versions. When I use a different WiDi-enabled computer to connect to the same monitor, everything works fine. When I use the original computer and receiver to connect to a TV, everything works fine. It's only when I connect the original computer to the monitor I want to use that the connection fails. What could be going wrong here, and how can I get the video to work consistently?

  • Windows 8 & Hyper-V Can't Bridge Wifi Connection

    - by xinunix
    So I have an odd issue that I can't quite figure out... I am running Windows 8 Enterprise on a Dell 6420 laptop. I have a Broadcom 802.11n wireless adapter. I am connected to an home router (Netgear WNDR3700) that is connected to the internet. It is a very simple home network setup. I am trying to stand-up a few VMs in Hyper-V and want the VMs to be able to access the internet over my wireless connection. I have found numerous examples of how to set this up using both External and Internal Virtual Switches but have yet to be able to get it to work on my machine. I have narrowed the issue down to the fact that my host machine always loses internet connection when I bridge my wifi connection (both when it is bridged automatically by windows when I setup an external virtual switch bound to the wifi adapter or if I do it manually by creating an internal virtual switch, right click on it and my wifi network and select "Bridge Connections".) In both cases after the bridge is established, my host machine can no longer connect to the internet. I am not sure where to start with troubleshooting this problem. After the bridge is setup, an ipconfig shows all netowrk devices on the machine as "Media Disconnected". I do know that the wireless adapter is connected to the router b/c it shows the connection as active and full-strength. The only thing I can possibly think of is that this machine also has the Cisco VPN client installed on it which installs a Cisco Virtual Network Adapter. Is it possible that this Cisco Virtual Adapter is causing me issues when I try to bridge? I saw some people had a similar issue with a VirtualBox virtual adapter when trying to share via Hyper-V. Any thoughts or suggestions on how to troubleshoot?

  • Wireless USB keyboard and mouse can wake system, but then receiver is inactive

    - by BlueMonkMN
    I have a Microsoft brand USB device that acts as a receiver for a wireless Microsoft Keyboard and a wireless Mouse. When it's operating normally, there are LEDs on the device indicating Caps Lock, Num Lock and Function Lock, of which the latter 2 are usually lit. It is plugged into a Dell Isnpiron 531 with Windows 7 32-bit running on an AMD Athlon 64 X2 Dual Core processor 5000+. When the computer goes to sleep (the power indicator on the main box is flashing), I can wake it by moving the mouse. So far all is good. However, something changed in, I think, the past couple weeks (I suspect due to a Microsoft driver update problem). Before the change, after waking the computer, everything would operate normally as far as I could tell, but now after waking the computer, the receiver has no lights on, and the keyboard and mouse are completely unresponsive (which is odd, considering the mouse woke up the computer). There is a button on the receiver that's supposed to reset the wireless connection and flash the lights while it does so, but it has no effect in this state. It's like the receiver doesn't have power (but how would the system know I moved the mouse, unless the power was on until it woke up?). I have checked the BIOS/CMOS settings or whatever you call them, and did not see anything related to USB in the power management section. I have checked Windows 7 device manager and ensured that all the USB Root Hub devices have the setting unchecked for allowing the USB power to be turned off. Like I said, this was working before, and the only thing I can think of that's changed is applying Windows Updates.

  • Symantec Protection Suite Enterprise Edition

    - by rihatum
    We (our company) are planning to deploy Symantec Endpoint Protection and Symantec Desktop Recovery 2011 Desktop Edition to our 3000 - 4000 workstations (Windows7 32 and 64) with a few 100s with Windows XP 32/64 Bit. I have read the implementation guide for SEP and have read tech-notes for Desktop Recovery 2011. Our team have planned to deploy this as follows : 1 x dedicated SQL 2008R2 for Symantec Endpoint Protection (Instead of using the Embedded Database) 1 x Dedicated SQL 2008R2 for Symantec Desktop Recovery 2011 (Instead of using the Embedded Database) 1 x Dedicated W2K8 R2 Box for the SEPM (Symantec Endpoint Protection Manager - Mgmt. APP) 1 x Dedicated W2K8 R2 Box for the Symantec Desktop Recovery 2011 Management Application Agent Deployment : As per Symantec Documentation for both of the above, an agent can be pushed via the Mgmt. Application (provided no firewalls are blocking ports required etc. - we have Windows firewall disabled already). Above is the initial plan we have for 3000 - 4000 client workstation (Windows) Now my Questions :-) a) If we had these users distributed amongst two sites with AD DC / GC in each site, How would I restrict SEPM and Desktop Mgmt. solution to only check for users in their respective site ? b) At present all users are under one building but we are going to move some dept. to a new location (with dedicated connectivity), How would we control which SEPM / MGMT Server is responsible for which site ? c) What Hardware would you recommend as a Server spec for the SQL server 16GB RAM, Dual XEON? d) What Hardware would you recommend as a Server spec for the MGMT Servers 16GB RAM each with DUAL xeon and sas disks? e) Also, how do you or would you recommend to protect these 4 servers (2 x SQL and 2 x MGMT Servers)? f) How would you recommend to store backups for these desktops? We do have a SAN and a NAS in our environment and we do have one spare DAS (Dell MD3000). If you have anything to add / correct - that will be really helpful before diving into the actual implementation phase. Will be most grateful with your suggestions, recommendations and corrections with above - Many Thanks ! Rihatum

  • Cheapest iSCSI SAN for Windows 2008/SQL Server clustering?

    - by MichaelGG
    Are there any production-quality iSCSI SANs suitable for use with Windows Server 2008/SQL Server for failover clustering? So far, I've only seen Dell's MD3000i, and HP's MSA 2000 (2012i), which both are around $6K with a minimal disk configuration. Buffalo (yea, I know), has a $1000 device with iSCSI support, but they say it will not work for 2008 failover clustering. I'm interested in seeing something suitable for failover in a production environment, but with very low IO requirements. (Clustering, say, a 30GB DB.) As for using software: On Windows, StarWind seems to have a great solution. But it's actually more money than buying a hardware SAN. (As I understand, only the enterprise edition supports having replicas, and that's $3000 a license.) I was thinking I could use Linux, something like DRBD + an iSCSI target would be fine. However, I haven't seen any free or low-cost iSCSI software that supports SCSI-3 persistent reservations, which Windows 2008 needs for failover clustering. I know $6K isn't much at all, just curious to see if there are practical cheaper solutions out there. And finally, yes, the software is expensive, but many small business get MS BizSpark, so the Windows 2008 Enterprise / SQL 2008 licenses are completely free.

  • Purge print driver cache on windows 7 with powershell script

    - by Doltknuckle
    [Background] We have been having trouble with our network clients suddenly being unable to print. They get an odd error with a hex code. We determined that something in the driver was messed up and we could resolve the issue by clearing the driver cache and reinstalling the driver. This happens to random computers every so often. We're assuming this is a bug with the latest Dell 2330dn driver since that is the only model that has this problem. [Problem] What we are looking to do is write a Powershell script that would clear the driver cache and redownload the driver. I see a ton of scripts out there to manage queues, servers, and ports, but nothing for local driver cache management. [Current Workaround] Since we have to do this manually, I'll write out the steps so you know what we want this script to replicate. Disable print spooler Restart machine Delete contents of: C:\windows\system32\spool\drivers\w32x86 Enable print spooler and start service. Delete the network printer object and re-add network printer off of server. [Request] I'm good enough with powershell to translate the above workaround into a pair of scripts. I'd like to find a more elegant solution then my current workaround. Any suggestions?

  • What LTO 4 drive to buy

    - by pplrppl
    Evan Anderson mentioned in another solution you could buy a LTO-4 (autoloader, 1 tape / day) - $4,566.00 (the discussion included total cost of tapes for a specific rotation.) but I don't know specifics on what he or you would recommend for the actual drive and if necessary controller. Show me a newegg URL or CDW, Dell, or HP, or whatever your favorite vendor would be for your solution if you don't mind looking it up or just give me a brand and a model number and I'll be glad to do the leg work myself. I currently have on have on hand an external LTO 3 drive that uses LVD SCSI interface (and thus have a controller card that has an external LVD SCSI connector). If that card isn't sufficient to interface to a LTO 4 drive let me know. http://www.fujifilmusa.com/shared/bin/LTO_Overview.pdf shows minimum tape speeds for LTO4 and other LTO formats. It looks like the IBM LTO4 actually has a lower minimum speed than the IBM LTO3. Either way my average server is too slow to feed LTO3/4 without shoeshining so I'm looking for a drive with a low minimum write speed. If you trust the PDF from 2008 that makes my choices IBM LTO 4 full height IBM LTO 4 half height HP LTO 4 half height but presumably there are other options out there that weren't mentioned in the fuji PDF. Again I'm looking for a specific recommendation on a drive to buy (and the controller if needed).

  • How to use Python to read the physical address(MAC ID) [closed]

    - by getjoefree
    I want to read the physical address of the NIC model, i can get the results that i want to with SED.EXE before, but SED.EXE does not support my environment but Python ok, who have the means to do it. The general situation (not plug the network cable, it is impossible to obtain IP address): Ethernet adapter: Connection-specific DNS Suffix.: Chianet Description ...........: Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller Physical Address .........: A4-BA-DB-9D-1E-8E Dhcp Enabled ...........: Yes Autoconfiguration Enabled ....: Yes Ethernet adapter 3: Media State . . . . . . . . . . . : Media disconnected Description . . . . . . . . . . . : Dell Wireless 1510 Wireless-N WLAN Mini-Card Physical Address. . . . . . . . . : 00-23-4D-D9-C0-28 The description of the NIC different, we can use this to fetch the corresponding physical address, base on Physical Address does not work, because the computer with the WLAN Card, I want to use Python to read my computer the card information and after Python handles an output file, output file format: SET MAC = A4BADB9D1E8E and sed format: ipconfig -all|sed -nrf getmac.sed | sed -e "s/-//g" > WINMAC.BAT getmac.sed: /Marvell Yukon 88E8040/ { n; s/.*: ([-0-9A-F]+)/set winmac=\1/p; }

  • How to Secure a Data Role by Multiple Business Units

    - by Elie Wazen
    In this post we will see how a Role can be data secured by multiple Business Units (BUs).  Separate Data Roles are generally created for each BU if a corresponding data template generates roles on the basis of the BU dimension. The advantage of creating a policy with a rule that includes multiple BUs is that while mapping these roles in HCM Role Provisioning Rules, fewer number of entires need to be made. This could facilitate maintenance for enterprises with a large number of Business Units. Note: The example below applies as well if the securing entity is Inventory Organization. Let us take for example the case of a user provisioned with the "Accounts Payable Manager - Vision Operations" Data Role in Fusion Applications. This user will be able to access Invoices in Vision Operations but will not be able to see Invoices in Vision Germany. Figure 1. A User with a Data Role restricting them to Data from BU: Vision Operations With the role granted above, this is what the user will see when they attempt to select Business Units while searching for AP Invoices. Figure 2.The List Of Values of Business Units is limited to single one. This is the effect of the Data Role granted to that user as can be seen in Figure 1 In order to create a data role that secures by multiple BUs,  we need to start by creating a condition that groups those Business Units we want to include in that data role. This is accomplished by creating a new condition against the BU View .  That Condition will later be used to create a data policy for our newly created Role.  The BU View is a Database resource and  is accessed from APM as seen in the search below Figure 3.Viewing a Database Resource in APM The next step is create a new condition,  in which we define a sql predicate that includes 2 BUs ( The ids below refer to Vision Operations and Vision Germany).  At this point we have simply created a standalone condition.  We have not used this condition yet, and security is therefore not affected. Figure 4. Custom Role that inherits the Purchase Order Overview Duty We are now ready to create our Data Policy.  in APM, we search for our newly Created Role and Navigate to “Find Global Policies”.  we query the Role we want to secure and navigate to view its global policies. Figure 5. The Job Role we plan on securing We can see that the role was not defined with a Data Policy . So will create one that uses the condition we created earlier.   Figure 6. Creating a New Data Policy In the General Information tab, we have to specify the DB Resource that the Security Policy applies to:  In our case this is the BU View Figure 7. Data Policy Definition - Selection of the DB Resource we will secure by In the Rules Tab, we  make the rule applicable to multiple values of the DB Resource we selected in the previous tab.  This is where we associate the condition we created against the BU view to this data policy by entering the Condition name in the Condition field Figure 8. Data Policy Rule The last step of Defining the Data Policy, consists of  explicitly selecting  the Actions that are goverened by this Data Policy.  In this case for example we select the Actions displayed below in the right pane. Once the record is saved , we are ready to use our newly secured Data Role. Figure 9. Data Policy Actions We can now see a new Data Policy associated with our Role.  Figure 10. Role is now secured by a Data Policy We now Assign that new Role to the User.  Of course this does not have to be done in OIM and can be done using a Provisioning Rule in HCM. Figure 11. Role assigned to the User who previously was granted the Vision Ops secured role. Once that user accesses the Invoices Workarea this is what they see: In the image below the LOV of Business Unit returns the two values defined in our data policy namely: Vision Operations and Vision Germany Figure 12. The List Of Values of Business Units now includes the two we included in our data policy. This is the effect of the data role granted to that user as can be seen in Figure 11

  • Huge host CPU usage in idle vmware guest. Ubuntu 10.04 host, Vista SP2 guest

    - by themesandmodules
    I'm experiencing huge host CPU usage with an idle vmware guest. Host: Ubuntu 10.04 32-bit 2.6.32-24-generic-pae. (Very new install, i.e 24 hours ago) Hardware is Dell XPS M1530 laptop, 4GB ram. Intel Core II Duo T9300 2.50Ghz The virtualization setting "VT" or something is enabled in my bios. Guest: Completely fresh install of Windows Vista, upgraded to latest SP2 and all windows updates installed. 1024 - 1512MB ram allocated. Absolutely no other software installed on it, apart from VMWare tools. Situation When the guest is doing absolutely nothing, I watch with sysinternals process watch on the guest. This shows that system idle process is between 70 and 99%, usually around 95%. No actual process doing anything. On the host, I watch with top, I get cpu usage of 20% - 80%, usually around 30%. What I have tried Single and Dual processor available to guest - no change. Turn off all peripherals to guest - no network, drives, usb etc - no change. Turn off 3d acceleration for guest - perhaps a small improvement, or no change. Upping allocated ram to guest from 1024MB to 1512MB - no change. Yelling at vmware - no change. I have experienced a similar issue in the past, which was solved by setting the guest to have 1 CPU. This time that hasn't worked.

  • Windows XP dual screen problems, user account related

    - by Chris
    I have had this issue with a few laptops now and it looks like it is some sort of user account problem. Specifics of the system are: Dell Laptop Windows XP Pro SP3 Non-domain member computer DLP Projector connected to laptop via VGA I use this setup almost daily to do presentations, always the mirrored display mode where I can see on the laptop monitor the same thing that is displayed on the projector. Today, when I boot up, I get the mirrored display at the login screen, but after I log in, it switches to Extended Desktop (like two desktops side-by-side). Fn+F8 just cycles through all the normal settings except the mirrored display. I created a new user account on the computer and it performs normally. Mirrored display works as normal. I have run into this about 4 times now and it always can be solved by creating a new user account on the computer, and then all is well. I would like to either: 1. Find a way to reset the customized settings for a specific user account which would hopefully make this go away, or 2. Find the specific setting that causes this so that I can easily fix it when the problem comes up. Creating new user accounts is kind of a pain and a easy fix must be out there somewhere.

  • sql 2008 disk layout on a budget this is for database mirroring

    - by user22215
    Guys I'm rolling out a SQL database server that will be used to back Sharepoint 2007. Right now I need some advice on my disk layout. I have two Dell servers that are configured a little differently in terms of storage. The principle server will be using a combination of local storage and san storage. I have to work with what I have the organization is currently all allocated on san storage it was like pulling teeth to even get what I have to work with now. My disk setup on the principle is as follows: raid 1 for OS raid 10 for logs raid 10 fiber on san for high IO databases raid 10 sata on san for content databases My question in regards to the principle server is where should I place the temp db? I thought about placing it on the fiber raid 10 which will be hosting my high IO Sharepoint SSP databases my only other choice is to move it to the raid 1 os partition which I’m sure you guys will be against. Now let’s talk about the mirror server it is not connected to the san it is all local 6 15k SAS drives. Now my question is the same do I put tempdb on the os partition or do I leave the os partition and use a single raid 10 for everything? Any help you can provide is much appreciated.

  • Hourly SQL Server 2005 Slowness (Possibly caused by SYSTEM)

    - by Zorlack
    We're trying to diagnose the cause of slowness on our Database server. We're running the latest rev SQL Server 2005 on Windows 2008x64. The behavior that we're seeing is this: We see the SYSTEM process spike one of the CPUs for about 2 minutes, during this time SQL server slows down by a factor of 10. The slowness lasts until SYSTEM is done, then in an hour everything starts again. During these slowdowns disk writes don't spike, paging doesn't spike, the only noticeable precursor we see is that SYSTEM maxes out one of the sixteen (HT)CPUs. Note that this doesn't happen at the top of the hour, it just happens once an hour, and it shifts a bit depending on the length of the incident. At the moment this is causing intermittent slowdowns, but when the server is really busy it can cause Worker Thread starvation. The server is a Dual Quad Dell R710 with 96GB of RAM and RAID10 data/log disks. Has anyone experienced this kind of problem? Does anyone know where we should look?

  • graphics performance better on battery?

    - by Scott Beeson
    Anyone have any idea why my laptop would perform (considerably) better while on battery than while plugged in? It's a Dell Latitude E6420 with Windows 8 Pro. I tried mirroring all the settings in the selected power plan from "On battery" to "Plugged In" and that didn't help. I then just restored the defaults for all power plans (balanced and high performance). I'm still seeing the same results. The best example where it is most noticeable (don't laugh) is Sim City Social in Chrome. I'm probably seeing a performance increase of 5x on battery versus plugged in. This is easily reproducible too. I'm very confused. Could it be caused by dust? The laptop isn't that old and there is no visible dust. I'm not going to take it apart to check the insides as it's a corporate laptop. Could it be overheating? Battery Sim City Social: 68 degrees max Civ V: 77 degrees max Charger Sim City Social: 68 Civ V: did not test See answer below... I'm retarded

  • Windows 7 Not Starting and System Repair Not Loading

    - by Mark
    I have a Dell Inspiron 1545 running Windows 7 When turning on my PC I keep receiving a black screen with the option to use System Repair or Start Normally. Both options lead me to the System Repair background except no matter how long I wait the system restore options never show up. Choosing F8 and running all of the options including safe mode encounters the same result above. I tried to to use 2 system recovery disks 32x and 64x I downloaded and both lead to similiar results. When I choose System Repair running from the disk the System Repair Question asking to select a language pops ups but after this no matter how long I wait no other options appear. Next after restarting and selecting F8 (after hitting f12 and running from CD) I choose 'Run From Safe Mode with Command Prompt' I am able to run all of the options from System Restore with differing results: Startup Repair: Choosing this ends up in system repair indefinitely (left running 12 hrs) System Restore: Does Nothing. PC thinks for a second and then stops. When selecting ShutDown I see an error message stating there are no restore points. System Image Recovery: Service Cannot be started in Safe Mode Windows Memory Diagnostic: Runs test but then leads to system repair background which never loads system repair Command Prompt: chkdsk /r -Cannot Lock Current Drive...write protected. chkdsk /f -Cannot Lock Current Drive...write protected. bootcfg - Cannot open Boot.Ini file bootcfg - Ran all 3 (rebuildBcd, FixMbr and Fixboot) but PC still goes to System Repair background with no repair options popping up upon restart (without recovery CD). I'm on the verge of purchasing a boot utility disk for $50 unless there is anything else short of "take it to a computer shop" that somebody can suggest I try.

  • Internet Connection not working - USB LAN connection - from particular modem

    - by Paul
    I am trying to fix Internet connection on a friends Dell inspiron 1720 with XP service pack 3. It has an integrated network card that stopped working, after powering down/up the modem still didnt work I brought it back to my place to try a few things ie check cable, update driver etc... still didnt work. So I bought a USB LAN connector. It didnt work straight away but I went to configure the properties and changed the ConnectionType from AutoSense to 100 BaseT 10BaseT Full_Duplex, I basically just tried them all. From my place when connected to my desktop - 10 BaseT and 10BaseT Full_Duplex worked. From my place When connected to their laptop - 10 BaseT and 10BaseT Full_Duplex worked. Happy I went back to my friends house confident it would all work, and it didnt. Brought it back to mine and it did. While there, in Network Connections the connection is there recognized, enabled, 'working properly' it just says not connected. Also there is no led on the USB connector While at mine as above except there is an led on the USB connector and it says connected. Other difference I can think of is they have a cable modem, I'm plugged into the back of a Belkin wireless router - would this make a difference? Any other ideas what to try? (Would getting the model of the cable modem help anyone?) The USB connector is "DM9601 USB to Fast Ethernet"

  • Choosing a new laptop

    - by chiongms
    I'm looking for a new laptop. I saw few: i) HP ProBook 4321s ii) HP ProBook 6440b iii)Dell Latitude E6410 i found these laptops are still very new..is it? not much comments about them. can anyone help? i doubt how their graphic cards perform compare to each other? ProBook 4321s- Radeon HD4350 ProBook 6440b- Radeon HD4550 Latitude E6410- NVS 3100M most of the time i'll running 3D CAD software, C++ programing...i saw my friend's laptop with radeon HD4350. it's perfectly fulfilling my demand. but i wonder how the other two are? Another thing i doubt is the screen resolution..my current laptop is 1280x800, and i found it comfortable to use. But these two HP only offer 1366x768..will it make any large different? Lastly, is there anyway to estimate how their power consumption is from the spec sheet? well, i would prefer one with longer battery usage time. my current laptop is suck...only last 1 hour even when it's still new..i'm not going to get another like this anymore. Anyone can help me please? Thanks!

  • Access Windows Boot Manager selector when timeout is set to 0?

    - by Kyle Cronin
    I've installed Wubi onto a Windows Vista computer. I've also set the boot timeout to 0: bcdedit /timeout 0 However, now I can't figure out how to get the menu to come up at all! I read on the internets that I had to hold F8 or space when starting up, but they doesn't seem to do anything. Is there a different key or setting I've overlooked? The computer itself is a Dell that's a few months old. The keyboard is USB, but I don't think that's the problem as I can get into the BIOS just fine. Maybe I'm doing it wrong? Am I supposed to hold the keys or rapidly tap them (I've tried both)? If it helps, here's the output from bcdedit: C:\Windows\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=C: description Windows Boot Manager locale en-US inherit {globalsettings} default {current} resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} displayorder {current} {e2484fe7-5e97-11de-84d4-0024e8074422} toolsdisplayorder {memdiag} timeout 0 resume No Windows Boot Loader ------------------- identifier {current} device partition=C: path \Windows\system32\winload.exe description Windows Vista locale en-US inherit {bootloadersettings} recoverysequence {572bcd55-ffa7-11d9-aae0-0007e994107d} recoveryenabled Yes osdevice partition=C: systemroot \Windows resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} nx OptIn Real-mode Boot Sector --------------------- identifier {e2484fe7-5e97-11de-84d4-0024e8074422} device partition=C: path \ubuntu\winboot\wubildr.mbr description Ubuntu

  • ESX 4.0 space: DASD, NAS, or ?

    - by thormj
    I put together an ESX box for better management, but its performance is a WTF item; I'm a noob at dealing with ESX, so I'm looking for a laundry-list of reading material to help me straighten this out so I can go back to .NET programming. Current storage system: We're running Raid5+Hotspare (8x500 GB spindles) on a PERC6i on a Dell 2910. Due to ESX limitatios, the PERC is showing the storage as 1x2TB + 1x800GB "partitions." I'm not sure of the setup's configuration (stride / stripe / ???) at all. Our Applications We have a SBS server as well as a minor (2x50 GB, but growing at 10GB/month) database server... Our application that lives on the database VM is CPU and I/O insense; it's a database churning excercise mixed in with a lot of computation on the data (fixing that performance is what I'm supposed to be working on)... Perfomance Issue When I do a backup, restore, or worse (copy a backup from 1 vm to another to move it to the QA VM), the entire system slows to a crawl (even "unrelated" VMs). I originally thought a DASD situation would be quite good since you had PCI-x bandwidth, but the systemwide slowdown is killing productivity. Questions What should I do to make an intelligent decision about NAS vs RAID vs SAN vs DASD? Are there sweet spots/ugly spots in the storage setup? Can you use a SSD PCI-X card in ESX for the tempdb? Good/Bad idea? Is there any way to "share" some image in a copy-on-write fashion? Most of the "Backup-Copy-Restore" is to "put a clean image on the dev boxes"; if I could have them "share" the master image, the "big copy" (2x50 GB) would only need to be done once per week instead of once per dev per week...[runtime performance isn't a concern with the dev boxes, but the backup/copy/restore kills production, SBS, and everything else on the box]

  • x display problems in centos 5.5

    - by John Ruiz
    I have a Dell E510 desktop with a geForce 7200 instead of the ATI x600 it came with. I have attempted to install CentOS 5.4 x86_64 (DVD), CentOS 5.5 (net install), and CentOS 5.5 x86_64 (DVD). Gnome desktop. All of these run into the same issue. When I put the DVD into the machine and reboot, the installer begins and I select "graphical install". I see text that say anaconda is starting, and then my screen goes nuts. It's not black, but rather a screen full of diagonal stripes or multiple colors. So I attempted to do a text install of CentOS 5.5 (DVD) and got it installed. When I booted for the first time, I logged into the virtual console and started X (startx). The desktop came up and it already had the display properties GUI up. I changed it from 800x600 to 1680x1050, saw that there were updates available, installed them, and then rebooted. When I start X from the virtual console this time, I get exactly the same display problem as I described before. Does anyone know what might be causing this and what I can do about it? edit: I should also mention that I'm capable of installing Windows 7 and Ubuntu 10.04 onto this machine with absolutely no issues at all.
