• Where does Rundesk execute local tasks from

  - by Leon Stafford

  I'm trying to interact with the nodejs Azure sdk from a CentOS installation of Rundeck. If I try from the "run" adhoc virtual shell, I am able to after running azure account import <mykey> and can then also execute other Azure commands inside of jobs if I set them as Rundeck node tasks and not selecting "dispatch to nodes" in the job settings. Trying to run the Azure sdk commands as commands to be dispatched to the node (local) fails with the error: localhost1-NodeDispatch-localexec 04:53:04 /usr/bin/env: node: No such file or directory 04:53:04 Failed: NonZeroResultCode: Result code was 127 I am not able to "jumpstart" the same environment by running azure account import <mykey> I am assuming this is a permissions/environmental issue, though not sure how to fix it. UPDATE: Executing whoami from the same job returns rundeck, so I assume I will need to either modify that to execute tasks as my system user or grant permissions to get the rundeck user into the node environment the Azure sdk is running in?

• Deploying in windows 2008 [closed]

  - by Blisk

  Possible Duplicate: How is software deployed via Active Directory? I have trying to deploy a programs, mapped network drives and taks schedule job. I didn't manage to start a script on log on PC until I did it in Default Domain Policy. But when I did that I have installed programs on my server too. And mapped network drives, etc. So I don't know how to manage to do all of that but not to install anything on server over GPO. I still didn't manage to deploy a schedule task job on clients. I manage to put it on server bit not on clients. I need that schedule task because I need to update software on clients every week. I can't manual update flash player, adobe reader, firefox, etc on clients. And People useing client PC even doesn't know how to do it if they have abillity. Clients doesn't have admin rights.

• Should my servers boot from VHD?

  - by tony roth

  I've been testing native vhd boot on several servers. It seems to be pretty transparent in terms of deployment and with my seat of the pants testing I have not noticed any difference in performance. The main reason that I want to boot vhd is due to their transportablility between different hardware and to hyper-v servers. the following roles will be installed. dfsr dhcp iis application server dc <- haven't tested this yet but see no reason why it won't work. With the above low impact (in terms of performance) roles do you thing booting from VHD is appropriate. thx

• What is the best file system and allocation size for a USB flash drive?

  - by e-t172

  I'm considering using my 4 GB Kingston DataTraveler USB stick to store my Firefox and Thunderbird profiles for my laptop and desktop PCs. I want to maximize performance when using Firefox. The question is: what is the best file system and allocation size for the fastest Firefox profile operation on a USB flash drive? I'm using Windows 7 on both machines and I don't care about compatibility or the drive's lifetime. I just want to maximize performance. I could even use ext2 with the Ext2 IFS driver if that means it'll be faster. I'm assuming (perhaps I'm wrong) that putting a Firefox profile on a USB stick would be a "lots of small files" usage. In that case, it seems that NTFS would perform best, but I'm not sure. Besides I found nothing regarding the best allocation size to use. Considering that the default allocation size is designed for hard drives (which have different characteristics), I'm assuming that the default allocation size is not the best.

• Printer monitor software across multiple workstations (AD integrated)

  - by HannesFostie

  I was asked to see if there is any kind of (free) software that allows multiple people in an office that use the same printer to see what jobs have finished recently, which are queued and which is printing. Main reason is that sometimes multiple people have the same task where they need to print some kind of form, and they are unsure whether or not their colleague has already printed the file. Because the printer is AD integrated, they only see a short message when printing, but they do not see a proper printer queue. A simple tray icon/tool would be perfect, no real graphical user interface is required. If this turns out to be too hard to find, I will attempt to write a simple application or script for the job, but since this is a low priority job I decided to ask here first before I start messing around with scripting which isn't my forte. Thanks

• Video memory buswidth vs video memory Bandwidth

  - by Mixxiphoid

  My current video card (9600GT) is dying and I'm searching for a new video card. Between acquiring my current one and now, I got a lot more knowledge about hardware and I want to use that to pick my new card. So I decided to not just buy some popular card blindly, but to search for a card able to handle my hardware requirements. I searched the specs at the NVidia site for the GT640 and was confused by the memory section and some questions raised. My current card's memory bus width is 256bit and has 1GB of memory. I checked Google about the importance of bus width. And all the links basically said the same 'The higher the number the more potential simultaneously traffic can be transferred'. This was already clear to me, yet there are currently a lot of new cards which are considered better than my current one with a lower bus width. To go in more detail about my question I copied the memory info from the NVidia site: GT 640 GT640 GDDR5 Memory Specs: Memory Clock 1.8 Gbps 5.0 Gbps Standard Memory Config 2048 MB 1024 MB Memory Interface DDR3 GDDR5 Memory Interface Width 128-bit 64-bit Memory Bandwidth (GB/sec) 28.5 40.0 What puzzled me is that the Memory Bandwidth seems to me the most important part, yet the lower bus width has the higher 'performance'. Is this due to the fact the memory interface is GDDR5 and is therefore able to have a higher memory clock speed (5Gbps)? If I am to buy a new video card, should I check the bus width? Memory clock? Bandwith? Amount of memory? My current card ahs 1GB memory, so I was searching for a 2GB memory card, but now I'm not so sure any more whether that is really 'better'. My main question: To me it seems that memory performance is made up by the combination of bus width and frequency. Is this true? If yes, why are there so many sites telling me I need to get a card with a high bus width? If no, then what IS important when it goes about memory performance on a video card. NOTE: The memory bandwidth is (almost) never displayed on vendor sites. How can I determine which card is better without knowing the bandwith?

• differencing disk opinions

  - by troth

  I've read about the performance issues with dfferencing disks but I still think there is a solid place for them and thats the os boot partition. If I'm going to have 20 vms on a csv based volume I don't won't to waste the 20+ gigs per guest just for the os boot. If I get a good base disk with all of the most used applications installed and have the pagefile located somewhere else I don't think the delta's would be that great thus it should not create a performance issue. Also in a SAN based csv volumes does it make any sense in having the pagefile go to a seperate csv volume? Any opinions on this? thanks

• Why is the size of antivirus greater than that of anti malware? [on hold]

  - by Mistu4u

  Recently my computer was attacked by different kinds of worms and my computer was slowed down. So I tried to remove them by installing Avast free antivirus. The worms were copying themselves rapidly. But after installing avast, I observed it only blocked new copy of the worms to be created but could not delete the already created worms, even it could not find worms in a good amount. Then I downloaded Malwarewbyte Anti Malware and to my surprise I found out its service was way too better than Avast antivirus. It detected and deleted almost 2065 worms and malwares from my computer and now my computer is doing fine. As far as I know, anti malware functionality is also included in Antivirus, But then also its performance is poor. Now my question is if performance of antiviruses are meat to be poor than Antimalwares, then why the size of Avast is 179Mb and the size of Malwarebyte is 9.81mb?

• W3 Total Cache or WP Super Cache?

  - by javipas

  I'm just preparing the setup of a new VPS where I will migrate a WordPress blog with a good traffic (currently, around 40k pageviews a day), and I was thinking about the caching strategy. I've found different ideas and recommendations, but from previous experiences I will setup a Nginx+PHP-FPM+MySQL (LEMP) system on a Linode VPS. I've read also about setting Nginx as a reverse proxy with Apache, and even using Varnish too, but I don't know if all of this can benefit the speed/performance of the blog (that's the only thing that will be installed on the VPS). The question now is... would you recommend W3 Total Cache or WP Super Cache? I've used W3 on some blogs, but I haven't noticed great benefits and don't need all its options, so I think I could give the veteran WP Super Cache a try. Besides, some users have complained about W3 complex configuration and lack of performance (even consumig more CPU) on some cases.

• starting nginx via upstart

  - by Chiggsy

  Background: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS" I've built nginx, and I'd like to use upstart to start it: nginx upstart script from the site: description "nginx http daemon" start on runlevel 2 stop on runlevel 0 stop on runlevel 1 stop on runlevel 6 console owner exec /usr/sbin/nginx -c /etc/nginx/nginx.conf -g "daemon off;" respawn I get "unknown job" when i try to use initctl to run it, which I just learned apparently means there is an error, ( what's wrong with "Error" to describe errors?) Can someone point me in the right direction ? I've read the documentation , as it is, and it seems kind of sparse for a SysV init replacement... but whatever just need to add this job to the list, run it, and get on with what's left of my life... Any tips? EDIT: initctl version init (upstart 0.6.5)

  I downloaded java SDK from Google App Engine. I tried running appcfg.cmd from command prompt. But it gives this error. Error opening registry key 'Software\JavaSoft\Java Runtime Environment' Error: could not find java.dll Error: could not find Java 2 Runtime Environment. All i want to do with Google App Engine is to set up cron jobs with 1 minute frequency. I don't want to make any application in Google App Engine. I just want the cron job set up. Is there any way to set up cron job in Google App Engine without using the java SDK ???

• Mac OS X: at command not working

  - by David.Chu.ca

  I am going to schedule a job by using at command. Here I tried the following command: $ at now + 1 minute echo 'Test at command' <EOD> I saw the job is scheduled by using at -l. However, I saw no echo out. I guess that I may need to add user to at.allow file. I cannot find at.allow in my Mac (Snow Leopard). Not sure what I need to do to test this at command?

• Storing large amounts of small files into bigger files on Windows

  - by asmo

  Let's say I have 50 GiB of files that weights around 500 KiB each. My guess is that having, for example, 5 large files of 10 GiB each with the same content archived in them would be better for hard drive performance. Am I correct? Will there be a noticeable gain on an NTFS filesystem? ===================================================================== Finally, which tool could I use to group the files together while retaining the ability to modify the content of the archive with zero or minor performance loss? For example, I like TrueCrypt archiving because after mounting an archive file, it creates a drive which I can use seamlessly as if it was a normal drive. The only thing with TrueCrypt is that I don't need encryption/compression, only archiving.

• Unable to connect to Amazon EC2 without using PPK file

  - by Krishna

  I have a build job which runs on Hudson and synchronizes content from an Amazon AWS server. This is written in shell I have a PPK file given to me which can establish the connectivity Here is the problem. The build script I use doesn't establish the connectivity in the code. So, I manually connect the host thro the PPK file using Putty and then run the job, then it works fine I am new to the shell stuff. Could someone help me out by suggesting how I can establish connectivity using the PPK file in the shell so I do not have to do it manually thro Putty? Thanks, Krishna

• 64bit on core i5 with 2GB DDR3 RAM?

  - by Jacques

  Core i5 2.3 Ghz processor 512mb ATI HD 4570 2GB 1333 RAM 64bit Windows 7 Home Premium. Should I "down-grade" to 32bit? Does running 64bit with only 2GB RAM make the laptop weaker than running 32bit with 2GB RAM or is the performance pretty much the same? Is there any performance benefit to running 64bit with only 2GB RAM? Is there an impact on battery life between 64bit and 32bit. Should I maybe just add another 2GB RAM? Thanks.

• Is there a network "tee"-alike with one leg returning to /dev/null ?

  - by Steff Davies

  I've just built a new PostgreSQL server for my employers, which is happily replicating using WALs. I'm now left with the problem of verifying its performance. One nice way which came up in conversation is to break replication with the slave caught up and then direct all production traffic to both servers, discarding the responses from the new server and returning those from the current one to the clients. Once we're sure performance is OK, we re-sync the slave and can fail over with confidence. Bliss. This would require a TCP proxy capable of opening two outgoing connections for each incoming one, and discarding the data returned from one of them, which is a tricky thing to google for, it seems. Do the assembled brains know of such a thing, before I dive into libevent and write one?

• SQL Maintenance Cleanup Task Working but Not Deleting

  - by Alex

  I have a Maintenance Plan that is suppose to go through the BACKUP folder and remove all .bak older than 5 days. When I run the job, it gives me a success message but older .bak files are still present. I've tried the step at the following question: SQL Maintenance Cleanup Task 'Success' But not deleting files Result is column IsDamaged = 0 I've verified with the following question and this is not my issue: Maintenance Cleanup Task(s) running 'successfully' but not deleting back up files. I've also tried deleting the Job and Maintenance Plan and recreating, but to no avail. Any ideas?

• concatenate files including path in header - path contains spaces

  - by manolo

  I have to concatenate a number of files in a directory structure which contains spaces in the folder names looking like this: ./CH 0000100014/A10/11XT/11xt#001.csv find . -name "*.csv" -type f -print0 | xargs -0 cat > allmycsv.txt does the job, however now I need to include the information contained in the path, i.e. CH 0000100014/A10/11XT as a header of each inputfile to cat. find . -name "*.csv" -type f -print0 | xargs -0 -I % sh -c 'echo %; cat %' >allmycsv.txt would do the job, if I had no spaces in the path, but in my case, cat does not get along with the space in the path name. Is there a way out? Cheers, E P.S. I am working on bash on OSX

• querying sge using job_name

  - by user39212

  Hello, qstat manual says -j [job_list] Prints either for all pending jobs or the jobs con- tained in job_list various information. The job_list can contain job_ids, job_names, or wildcard expression sge_types(1). i.e. qstat -j job_name should work. But whenver I try i get an error saying qstat -j test_20100203_01 ERROR: job-ID should be an integer Any idea if this should have worked. I can also use: qstat | grep test_20100203_01 but the problem is that qstat lists the shortened job name (something like test_2010020 and not test_20100203_01). Please advise.

• Working WCF WebServices with NLB server

  - by gguth

  Im starting the architecture of a new project using WCF, but im not the right person to make some network considerations, so im doing some research but cannot find the answers to these questions: We´ll host the WCF service in a common Windows Service app in 2 servers and we´ll have another server to make the Load-Balancing job using the WNLB. The fact that we are hosting the WCF in a Windows Service app can disturb the NLB job? Before my research i thought the load balancing was tought to configure, but with NLB it seems to be very simple, its really that simple? Note: The binding will be basicHttpBinding

• A list of 'best practices' for extending the life between charges of a notebook battery.

  - by Tim Visher

  Hello Everyone, I'd like to compile a list of best practices for getting the most out of a single charge of a typical notebook battery (be it Li-Ion or Li-Poly). Sources would be great as well. I've heard, for instance, that the best things to do to improve battery performance (not the total lifetime of the battery, just single charge performance) are, in descending order of effectiveness: Turn your display all the way down. Turn off WiFi Turn off Bluetooth Spin down disks when they're not in use. etc… I'd like to get sources together for these and other tips for extending life-between-charge for any battery on any notebook (as these really are all about Demand Management rather than Life lime extension. Thanks!

• How do I perform an action if the upstart respawn limit is hit?

  - by Daniel Huckstep

  I have an upstart job: description "foreman" start on runlevel [2345] stop on runlevel [06] respawn respawn limit 3 60 chdir /home/deploy/app/current env RAILS_ENV=production exec sudo -u deploy bundle exec foreman start We ran into a case where a rogue character in an app file caused one of the background workers to fail but the app ran normally (weird). The app worked fine, but the workers were never working. I'd like upstart to do something (send an email) if it can't start this job, since it's not entirely obvious if everything went alright. Is there something built into upstart to handle this, or do I have to get creative?

• Provision storage in SAN encironment

  - by wildchild

  hi,.. Can somebody help in understanding how Lun Provisioning is done in clariion based on client requirement. Say, a client needs one 50 GB space on the host( for application) ,two -350 GBs ( for DB and stuff) on the same host and i have 4 raid groups with space of 200 GB in one 50 GB in second and 400 GB and 400GB in rest two all having 5 disks. And , I 'm using Raid 5 only. How do i provision keeping performance in mind( so that performance hit is not there)?..And i need to understand the concept of meta head as well. Please help me by elaborating the above scenario..I am learning to provision storage in non productive environment( b'fore going ahead and working on client prod server) and i have been learning a lot from SF ...I request the seniors here to help me understand it better. Thanks for reading
