  • VMWare Server :: VM set to 2gb RAM but vmware process shows 100mb physical, 1900mb virtual

    - by brad
    I've set up a VMWare instance to run CastIron Integration Appliance. I allocated 2gb of memory to the instance, assuming it would take this as physical memory (my server has 8gb total). When I view top however on the server, the vmware-vmx process has about 100m Resident memory and 1900m Virtual. Running CastIron it reports that the appliance often hits 50% memory usage. Does this mean I'm using 900mb of harddrive space as memory? I wanted VMWare to use 2gb of physical memory, no swap. Can anyone tell me how to achieve this? Setup Debian Lenny 5.0.3 VMWare Server 2.0.2

  • Table transformation / field parsing in PL/SQL

    - by IMHO
    I have de-normalized table, something like CODES ID | VALUE 10 | A,B,C 11 | A,B 12 | A,B,C,D,E,F 13 | R,T,D,W,W,W,W,W,S,S The job is to convert is where each token from VALUE will generate new record. Example: CODES_TRANS ID | VALUE_TRANS 10 | A 10 | B 10 | C 11 | A 11 | B What is the best way to do it in PL/SQL without usage of custom pl/sql packages, ideally with pure SQL? Obvious solution is to implement it via cursors. Any ideas?

  • supress warning for generated c# code

    - by soren.enemaerke
    I have turned on "Treat warnings as errors" for my VS project which mean that I get errors for missing documentation (nice reminder for this particular project). However, part of the code is generated by a custom tool which does not insert xml documentation so I'm looking for away to ignore the missing xml documentation for the generated code only, not for the entire project. I have no influence on the actual file generated and cannot really insert anything in the file (as it is regenerated frequently by the tool) so I looking for something existing outside the generated file (the classes that are generated are partial, if that helps)

  • Write to XCode build transcript.

    - by eaigner
    Is there any way to write to the XCode build transcript? What i want to do, is throw a warning if a device is not attached to the computer instead of an assertion failure in my unit test cases (some cases rely on an attached ipod). I thought of something like the standard compiler warnings (only with custom message). Thanks.

  • PowerShell script halts execution when Windows XP PC is locked

    - by jshin47
    I have the following script that does a continuous ping and reports failures. It works fine, except the loop apparently "suspends" when the computer is locked. I have confirmed this by starting the script, immediately locking the PC, waiting 10 minutes, and seeing how many pings have occurred. It is nowhere near the expected number. What could be the culprit? Write-Host "Entering monitoring loop..." -Background DarkRed $ping = new-object System.Net.NetworkInformation.Ping $count_up = 0 $count_dn = 0 $count_dd = 0 while ($true) { $result = $ping.send("10.1.1.1") if ($result.Status -eq "Success") { $count_up++ $count_dd = 0 } else { $count_dn++ $count_dd++ $this_date = Get-Date Write-Host "VPN ping failed at time " $this_date -Background Magenta if ($count_dd -gt 3) { Write-Host "***VPN is Down***" `a send_mail_notification("VPN is Down", "") } } if ($Host.UI.RawUI.KeyAvailable -and ("q" -eq $Host.UI.RawUI.ReadKey("IncludeKeyUp,NoEcho").Character)) { Write-Host "Exiting monitoring loop..." -Background DarkRed break; } Start-Sleep -m 250 } $total = $count_up + $count_dn $uptime = 100 * $count_up / $total Write-Host $count_up " out of " $total " pings for a " $uptime "% uptime."

  • Why is my iPhone WIFI so slow at home?

    - by John Fouhy
    When my iPhone is connected to my home wireless network, the internet is unusably slow. I installed the speedtest.net application; here are some results from tonight: Down: 0.0kB/s, Up: 0.0kB/s, ping: 2230ms Down: 2.5kB/s, Up: 40.5kB/s, ping: 2182ms Down: 0.0kB/s, Up: 20.0kB/s, ping: 197ms For comparison, here is the result from my iMac to the same server, which is on the same wireless network (and has no wired connection): Down: 139kB/s, Up: 53.8kB/s, ping: 182ms Neither my iMac nor the Dell laptop also on the network have experienced the wifi problems I get with my iPhone. On the other hand, I tried browsing a website on the wireless network at work with no problems. EDIT: SpeedTest at work gives me 156kB/s down. EDIT2: Girlfriend (owner of the Dell) reports actually the internet is sometimes very slow. Perhaps there is more going on. No problems with my iMac. My router is a ASUS WL-500g Premium V2 running OpenWrt Kamikaze with X-Wrt Extensions 8.09.

  • Calculating the number of occasions with a set period sumproduct function

    - by user158056
    =SUMPRODUCT((F16:F274=("A")) *(F17:F275<>("A"))) +SUMPRODUCT((F16:F274=("AH")) *(F17:F275<>("AH"))) +SUMPRODUCT((F16:F274=("AU")) *(F17:F275<>("AU"))) +SUMPRODUCT((F16:F274=("AHU"))*(F17:F275<>("AHU"))) I am using the above formula to add the number of occasions sickness occurs using the following as a key. It works fine until you get say an A and a AH in the same sickness period. Instead of reporting just one occasion off it reports two. Is there a way I can separate this? Absence A Absence 1/2 AH Absence Unpaid AU Absence 1/2 Unpaid AHU

  • Is there a free tool/package that can monitor web traffic and display URLS accessed? [closed]

    - by Anthony
    I couldn't find a similar question but then maybe I am searching for the wrong terms. A few years ago I used a router like device, I'm pretty sure it was a SonicWall, that did this on a clients site. Basically all traffic would be routed through this device and it allowed the manager/administrator to inspect web usage of the workers, determine how often certain resources were accessed and block them if necessary (much like content filter). It showed reports based on domain name reached etc. Facebbok.com, Bebo.com and so on. It also displayed the usual IP traffic information etc. it was a UTM also. I have tried Endian firewall, with it's NTOP install, but I don't think that will show URLs browsed. Maybe I just haven't found it in NTOP yet? I need this to troubleshoot connection and traffic issue at my home, with about twenty devices/users so didn't want to buy a dedicated solution and have spare hardware to use a community product.
