  • Must partprobe before using drive?

    - by Jeff Welling
    This is a followup question to Cannot mount /dev/sdc1 on Debian 5.0, special device /dev/sdc1 doesn't exist Basically, I have 6 SATA hard drives in a machine and I'm trying to create a RAID6 array with them. When I try to run the mdadm command to create (with the verbose option) a raid array, I see messages like "mdadm: super1.x cannot open /dev/sdf1: No such device or address" which are resolved by doing partprobe /dev/sdf and then re-running the mdadm command. The problem is that I have to run partprobe after each reboot, and from experience I don't think this is normal behaviour -- on no other linux machine do I have to partprobe the device before I can use it. Something must be going wrong, but how do I troubleshoot this to find out what? Could this be caused by a hardware problem? Edit: Additional note - before I seemed to only have this problem with one drive, but now I'm having it with 3 drives.

  • "net time" returns system error 5, "Access is denied", even when run as administrator

    - by Andrew Grant
    I am trying to run net time on a Windows 7 box with an account that is part of the Administrators group. When I run the command net time from an elevated command prompt I get the following error: System error 5 has occurred. Access is denied. Why is this happening? I've looked at this Microsoft Knowledge Base article and have gone through the steps. Both the computer and the DC are connected to the same NTP server and I've verified they're synced I'm working on a local account so there should be no permissions issues There is no local firewall running

  • How do i remove a password expiration policy?

    - by jimmygee
    We had a password expiration policy recently removed from our AD but some users continued to get the "..your password will expire in x days. would you like to change it now?" message. So we added a reverse/undo policy to correct the local registry settings Maximum password age = 0 days Minimum password age = 0 days This hasn't worked as new users still seem to encounter the above "change password" message sporadically. We have now removed all custom password policy GPOs and are left with the "Default Domain Policy". Still no good. Can someone point me in the direction to fix this? And an explanation into what i was doing wrong (/how password expiration policies apply) would be useful too. thanks Environment is 2k3 server with mostly XPsp2 clients.

  • Design For Asynchronous User Interface

    - by Sohnee
    I have been working on a integration that has posed an interesting user interface conundrum that I would like suggestions for. The user interface is displayed within a third party product. The state of the interface is supplied by calls to a service I have written. There can be small delays between the actual state changing the the user interface changing due to the polling for state by the third party. When a user interacts with the user interface, requests are sent back to my application. This then affects the state and the next state poll request will update the user interface. The problem is that the delay between pressing a button and seeing the user interface update is perhaps 1 or 2 seconds and in usability testing I can see that people are clicking again before the user interface updates, thinking that they haven't properly clicked the first time. Given the constraints (we can only update the user interface via the polling mechanism - if we updated it when they clicked, the polling might return and overwrite the change causing unpredictable / undesirable results)... what can we do to make the user experience better. My current idea is to show a message for a couple of seconds so people know their click was accepted, the message would not be affected by the state polling, so wouldn't be prematurely removed / overwritten etc. I'm sure there are other ideas out there and I'm also confident someone has a better idea that I have!

  • Why don't SCOM R2 web console performance views load?

    - by Nexus
    When I select any performance view via my SCOM R2 web console, I get the following error: Unexpected error There was an error displaying the page you requested. ... and some suggestions about restarting my browser, which doesn't resolve the issue. The request produces the following event in the logs: Event code: 3005 Event message: An unhandled exception has occurred.

  • Unix list absolute file name

    - by Matthew Adams
    Given an arbitrary single argument representing a file (or directory, device, etc), how do I get the absolute path of the argument? I've seen many answers to this question involving find/ls/stat/readlink and $PWD, but none that suits my need. It looks like the closest answer is ksh's "whence" command, but I need it to work in sh/bash. Assume a file, foo.txt, is located in my home directory, /Users/matthew/foo.txt. I need the following behavior, despite what my current working directory is (I'm calling the command "abs"): (PWD is ~) $ abs foo.txt /Users/matthew/foo.txt $ abs ~/foo.txt /Users/matthew/foo.txt $ abs ./foo.txt /Users/matthew/foo.txt $ abs /Users/matthew/foo.txt /Users/matthew/foo.txt What would "abs" really be? TIA, Matthew

  • proxy pass for activeMQ

    - by user1172482
    I have a apache server that I'm trying to use for proxy access my activeMQ admin page. I am able to load the inital landing page properly, but I can't seem to load any of the sub-pages (Queues, Connections, etc.). My proxypass rules on the apache server are the following: ProxyPass /foo http://10.5.124.108:8161/admin ProxyPassReverse /foo http://10.5.124.108:8161/admin The activeMQ installation included a activemq-httpd.conf file in /etc/httpd/conf.d/. Proxy connections there are enabled: ProxyRequests On ProxyVia On <Proxy *> Allow from all Order allow,deny </Proxy> ProxyPass /admin http://localhost:8161/admin ProxyPassReverse /admin http://localhost:8161/admin ProxyPass /message http://localhost:8161/admin/send ProxyPassReverse /message http://localhost:8161/admin/send From what I've read the proxypass rules should be recursive (the rule for /foo should also work for /foo/bar). Is there something else that I'm missing here that's preventing me from accessing pages beyond the initial admin landing page?

  • Emulate "Go to Dekstop/Home/etc." behavior in OS X via AppleScript

    - by pattulus
    OS X has build in support for going to certain Folders (Home, Utilities, Desktop, etc.) via a Shortcut. I wanted to emulate this behavior for the the Downloads Folder. The only thing that is missing the script below is that it won’t succeed when no window is opened in the Finder (see Error message). tell application "Finder" activate set target of Finder window 1 to folder "Downloads" of folder "username" of disk "Macintosh HD" end tell Error message: error "Finder got an error: Can’t set Finder window 1 to folder \"Downloads\" of folder \"username\" of disk \"Macintosh HD\"." number -10006 from Finder window 1 It great if you know about some kind of 'if-compliement' that triggers opening the Downloads Folder in case there is no window 1 open in the Finder. Thanks in advance.

  • Node remains in commissioning status

    - by Vinitha
    I have been trying to set up ubuntu cloud 12.04. I'm kind of new to MAAS and ubuntu. Here is what I followed. Have installed MAAS server using the steps provided in https://wiki.ubuntu.com/ServerTeam/MAAS For the node, I installed the Ubuntu 12.04 Server Image on a USB Stick. Then restarted the node and opted to enlist the node via boot media, with PXE. once the process was done, the node was powered off as expected. I manually powered on the node, as my node is not PXE enabled. Result - No node was visible on MAAS UI Since step 2 didn't work, I added the node via maas-cli. command. After the execution of this command I got the node reflected on to my MAAS UI. But the status continues to be in "Commissioning" for a long time. Then I executed "maas-cli maas nodes check-commissioning " and i got "Unrecognised signature: POST check_commissioning". I'm not sure where is the error. Could some one please help me solve this issue. I checked the following log file but found no error related to commissioning (pserv.log / maas.log / celery.log/celery-region.log). I found this entry in my auth.log "Nov 16 18:20:34 ubuntuCloud sshd[4222]: Did not receive identification string from xxx.xx.xx.x" not sure if it indicates anything as the ip that is mentioned is not of the node nor of the MAAS server. I also verified the time on the server and node using date cmd - (at one instance the times are : Server: Fri Nov 16 18:15:51 IST 2012 and Node Fri Nov 16 18:15:43 IST 2012). Not sure if 'date' the right cmd to set the time. I have also check maas_local_settings.py for the MAAS url. I'm not sure what are the logs that need to be verified. Is there any log that can be checked on the Node. Thanks Vinitha

  • Cannot receive email outside domain with Microsoft Exchange

    - by Adi
    This morning we couldn't receive email from outside our company's domain (domain.com.au), but we can send email to outside (e.g hotmail, gmail, yahoo). When I tried to send email to my work email address using my gmail account, I received this message Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unable to relay for [email protected] (state 14). I tried using telnet to send email, and it works. But still I couldn't figure out why I can't receive email from outside. I'm not sure if I provided enough info. I'll try to provide as much info as needed to help me solve the problem. Thanks

  • Begin the Clone Wars Have!

    - by Antony Reynolds
    Creating a New Virtual Machine from an Existing Virtual Disk In previous posts I described how I set up an OEL6 machine under VirtualBox that can run an 11gR2 database and FMW 11.1.1.5.  That is great if you want the DB and FMW running in the same virtual image and it has served me well for some proof of concepts and also for some testing of different JVMs.  However I also wanted to run some testing of FMW with the database running on a separate physical machine.  So in this post I will show how to take a VirtualBox image and create a new image based on the disks from that original image. What are my Options? There is more than one way to skin a cat, or in this case to create two separate VMs that can run on different hardware.  Some of the options include: Create new virtual disk images for each new VM. Clone the existing disk images and point the new VM at the cloned images. Point the new VM at the existing snapshots. #1 is too much like hard work, install OEL twice, install a database again, install FMW again, run RCU again!  Life is too short! #2 is probably the safest way of doing things.  VirtualBox allows you to clone a disk image for use in a separate machine.  However this of course duplicates the disk and means that it is now occupying 3 times the space, once for the original disk and twice more for the two clones I would need. #3 is the most space efficient way of doing things.  It does mean however that I can only run the new “cloned” images if I have access to the original image because that is where the base snapshots reside.  However this is not a problem for me as long as I remember to keep all threee images together.  So this is the approach we will follow. Snapshot, What Snapshot? As we are going to create new virtual machines based on existing snapshots we need to figure out which snapshot to use.  We do this by opening the “Media Manager” from within VirtualBox and moving the mouse over the snapshot images until we find the snapshots we want – the snapshot name is identified in the “Attached to:” comment.  In my case I wanted the FMW installed snapshot because that had a database configured for FMW alongside the FMW software.  I made a note of the filename of that snapshot (actually I just noted the first 5 characters as that was all that was needed to uniquely identify the snapshot file). When we create the new machines we will point them at the snapshot filename we have just checked. Network or NotWork? Because we want the two new machines to communicate with each other when hosted in different physical machines we can’t use the default NAT networking mode without a lot of hassle.  But at the same time we need them to have fixed IP addresses relative to each other so that they can see each other whilst also being able to see the outside world. To achieve all these requirements I created two network adapters for each machine.  Adapter 1 was a standard NAT mapping.  This will allow each machine to get a dynamic IP address (10.0.2.15 by default) that can be used to access the external world through the VBox provided NAT gateway.  This is the same as the existing configuration. The second adapter I created as a bridged adapter.  This gives the virtual machine direct access to the host network card and by using fixed IP addresses each machine can see the other.  It is important to choose fixed IP addresses that are not routable across your internal network so you don’t get any clashes with other machines on your network.  Of course you could always get proper fixed IP addresses from your network people, but I have serveral people using my images and as long as I don’t have two instances of the same VM on the same network segment this is easier and avoids reconfiguring the network every time someone wants a copy of my VM.  If it is available I would suggest using the 10.0.3.* network as 10.0.2.* is the default NAT network.  You can check availability by pinging 10.0.3.1 and 10.0.3.2 from your host machine.  If it times out then you are probably safe to use that. Creating the New VMs Now that I had collected the data that I needed I went ahead and created the new VMs. When asked for a “Boot Hard Disk” I used the “Choose a virtual hard disk file…” link to find the snapshot I had previously selected and set that to be the existing hard disk.  I chose the previously existing SOA 11.1.1.5 install for both the new DB and FMW machines because that snapshot had the database with the RCU completed that I wanted for my DB machine and it had the SOA software installed which I wanted for my FMW machine. After the initial creation of the virtual machine go into the network setting section and enable a second adapter which will be bridged.  Make a note of the MAC addresses (the last four digits should be sufficient) of the two adapters so that you can later set the bridged adapter to use fixed IP and the NAT adapter to use DHCP. We are now ready to start the VMs and reconfigure Linux. Reconfiguring Linux Because I now have two new machines I need to change their network configuration.  In particular I need to change the hostname, update the hosts file and change the network settings. Changing the Hostname I renamed both hosts by running the hostname command as root: hostname vboxfmw.oracle.com I also edited the /etc/sysconfig file and set the correct hostname in there. HOSTNAME=vboxfmw.oracle.com Changing the Network Settings I needed to change the network configuration to give the bridged network a fixed IP address.  I first explicitly set the MAC addresses of the two adapters, because the order of the virtual adapters in the VirtualBox Manager is not necessarily the same as the order of the adapters in the guest OS.  So I went in to the System->Preferences->Network Connections screen and explicitly set the “Device MAC address” for the two adapters. Having correctly mapped the Linux adapters to the VirtualBox adapters I then set the Bridged adapter to use fixed IP addressing rather than DHCP.  There is no need for additional routing or default gateways because we expect the two machine to be on the same LAN segment. Updating the Hosts File Having renamed the machines and reconfigured the network I then updated the /etc/hosts file to refer to the new machine name add a new line to the hosts file to provide an additional IP address for my server (the new fixed IP address) add a new line for the fixed IP address of the other virtual machine 10.0.3.101      vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.2.15       vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.3.102      vboxfmw.oracle.com      vboxfmw # Added by NetworkManager 127.0.0.1       localhost.localdomain   localhost ::1     vboxdb.oracle.com       vboxdb  localhost6.localdomain6 localhost6 To make sure everything takes effect I restarted the server. Reconfiguring the Database on the DB Machine Because we changed the hostname the listener and the EM console no longer start so I need to modify the listener.ora to use the new hostname and I also need to rebuild the EM configuration because it also relies on the hostname. I edited the $ORACLE_HOME/network/admin/listener.ora and changed the listening address to the new hostname:       (ADDRESS = (PROTOCOL = TCP)(HOST = vboxdb.oracle.com)(PORT = 1521)) After changing the listener.ora I was able to start the listener using: lsnrctl start I also had to reconfigure the EM database control.  I first deconfigured it using the command: emca -deconfig dbcontrol db -repos drop This drops the repository and removes any existing registered dbcontrols. I then re-configured it using the following command: emca -config dbcontrol db -repos create This creates the EM repository and then configures and starts dbcontrol. Now my database machine is ready so I can close it down and take a snapshot. Disabling the Database on the FMW Machine I set up the database to start automatically by creating a service called “dbora”.  On the FMW machine I do not need the database running so I can prevent it auto-starting by running the following command: chkconfig –del dbora Note that because I am using a snapshot it is not a waste of disk space to have the DB installed but not used.  As long as I don’t run it, it won’t cost me anything. I can now close the FMW machine down and take a snapshot. Creating a New Domain The FMW machine is now ready to create a new domain.  When creating the domain I can point it at the second machine which is running the database.  I can potentially run these machines on two separate physical machines as long as I have the original virtual machine available to both of the physical machines. Gotchas in Snapshotting VirtualBox does not support the concept of linked machines in a network like some virtualization technologies so when creating a snapshot it is a good idea to shut both VMs down and then take a snapshot on both of them.  This is because we want to keep the database in sync with the middleware.  One way to make sure that this happens would be to place all the domain configuration files on the database server via an NFS share, this would mean that all we would need to snapshot would be the database machine because that would hold all the state and configuration. The Sky’s the Limit We have covered a simple case of having just two machines.  I have a more complicated configuration in which two machine run a RAC database off the same base OS image, and two more machines run a SOA cluster based on the same OS image.  Just remember what machine holds state and what are the consequences of taking a snapshot.

  • How do I fix the error: CS1548: Cryptographic failure while signing assembly ?

    - by Paula DiTallo
    The full error in Microsoft Visual Studio on a compile looks like this: error CS1548: Cryptographic failure while signing assembly 'C:\Program Files\Microsoft SQL Server\100\Samples\Analysis Services\Programmability\AMO\AMOAdventureWorks\CS\StoredProcedures\obj\Debug\StoredProcedures.dll' This is likely due to a missing strong key pair value file. The easiest way to solve this problem is to create a new one. Navigate to:  Microsoft Visual Studio 2010>Visual Studio Tools>Visual Studio x64 Win64 Command Prompt (2010)  [if you aren't on an x64 box, pick another command prompt option that fits] Once the MS-Dos window displays, type in this statement: sn -k c:\SampleKey.snk Then copy the output *.snk file to project directory, or the *referenced directory. Remove the old reference to the *.snk file from the project. Add the paired key back to the project as an existing item. When you add back the *.snk file to the project, you will see that the *.snk file is no longer missing.   Our work is done!   *referenced directory: Pay attention to the original error message on compile. The *.snk file that is referenced may be in a directory path you aren't expecting--so you will still get the error unless you change the directory path or write the file to the directory the program is expecting to find the *.snk file.

  • DBan not working because disk has bad sectors?

    - by canadiancreed
    Attempting to wipe the drive of a laptop that I have before it's sold, and normally use DBAN to do so. However this time it starts and then finishes instantly with the following message. "DBAN finished with non-fatal errors This is usually cause by disks with bad sectors" Have tried multiple flags such as noverify to force it to skip this check (it doesn't show bad sectors in the OS scan in windows). but the error always comes back. This is the only time that I've seen this message, as every other of the few drives I've used this software on usually take 3-5 hours to do their job.

  • ODI 11g – Scripting Repository Creation

    - by David Allan
    Here’s a quick post on how to create both master and work repositories in one simple dialog, its using the groovy capabilities in ODI 11g and the groovy swing builder components. So if you want more/less take the groovy script and change, its easy stuff. The groovy script odi_create_repos.groovy is here, just open it in ODI before connecting and you will be able to create both master and work repositories with ease – or check the groovy out and script your own automation – you can construct the master, work and runtime repositories, so if you are embedding ODI as your DI engine this may be very useful. When you click ‘Create Repository’ you will see the following in the log as the master repository starts to be created; ====================================================== Repository Creation Started.... ====================================================== Master Repository Creation Started.... Then the completion message followed by the work repository creation and final completion message. Master Repository Creation Completed. Work Repository Creation Started. Work Repository Creation Completed. ====================================================== Repository Creation Completed Successfully ====================================================== Script exited. If any error is hit, the script just exits and prints any error to the log. For example if I enter no passwords, I will get this error; ====================================================== Repository Creation Started.... ====================================================== Master Repository Creation Started.... ====================================================== Repository Creation Complete in Error ====================================================== oracle.odi.setup.RepositorySetupException: oracle.odi.core.security.PasswordPolicyNotMatchedException: ODI-10189: Password policy MinPasswordLength is not matched. ====================================================== Script exited. This is another example of using the ODI 11g SDK showing how to automate the construction of your data integration environment. The main interfaces and classes used here are IMasterRepositorySetup / MasterRepositorySetupImpl and IWorkRepositorySetup / WorkRepositorySetupImpl.

  • FTP Server on AIX 6.1 returns - "A system call received a parameter that is not valid"

    - by Manglu
    A FTP Server that is built in with AIX (we are using version 6.1) returns this error message as a response code - "A system call received a parameter that is not valid" I am unable to see why the FTP Server returns such a value as response code. My search does not yield any results and am a bit dumbstuck on why this is happening. I can see some related responses which says the AIX server might return this strange looking message when some Concurrent I/O occurs but i can't see anything in the context of the inbuilt FTP Server. Looking for assistance.

  • Microsoft Test Manager error in displaying test steps caused by malware

    - by terje
    Sometimes the tool is blamed for errors which are not the fault of the tool – this is one such story.  It was however, not so easy to get to the bottom of it, so I hope sharing this story can help some others. One of our test developers started to get this message inside the test steps part of a test case in the MTM. saying “Could not load file or assembly ‘0 bytes from System, Version=4.0.0.0,……..” The same error came up inside Visual Studio when we opened a test case there. Then we noted a similar error on another piece of software – this error: A System.BadImageFormatException, and same message as above, but just for framework 2.0. We found this  description which pointed to a malware problem (See bottom of that post), that is a fake anti-spyware program called “Additional Guard”.  We checked the computer in question using Malwarebytes Anti-Malware tool.  It found and cleaned out 753 registry keys!!  After this cleanup operation the error was gone.  This is a great tool !  The “Additional Guard” program had been inadvertently installed, and then uninstalled afterwards, but the corrupted keys were of course not removed.  We also noted that this computer had full corporate virus scanning and malware protection, but still this nasty little thing still slipped through.

  • Execute Backup-SqlDatabase cmdlet remotely

    - by Maxim V. Pavlov
    When I run the following script line locally on an SQL Server machine, it executes perfectly: Backup-SqlDatabase -ServerInstance $serverName -Database $sqldbname -BackupFile "$($backupFolder)$($dbname)_db_$($addinionToName).bak" $serverName contains a short name of the SQL Server instance. SQL Server is 2012, so these new cmdlets work like a charm. On the other hand, when I am trying to perform a DB backup from a TeamCity agent machine like this (Through Invoke-Command cmdlet): function BackupDB([String] $serverName, [String] $sqldbname, [String] $backupFolder, [String] $addinionToName) { Import-Module SQLPS -DisableNameChecking Backup-SqlDatabase -ServerInstance $serverName -Database $sqldbname -BackupFile "$($backupFolder)$($dbname)_db_$($addinionToName).bak" } Invoke-Command -computername $SQLComputerName -Credential $credentials -ScriptBlock ${function:BackupDB} -ArgumentList $SQLInstanceName, $DatabaseName, $BackupDirectory, $BakId results in an error: Failed to connect to server $serverName. + CategoryInfo : NotSpecified: (:) [Backup-SqlDatabase], ConnectionFailureException + FullyQualifiedErrorId : Microsoft.SqlServer.Management.Common.ConnectionFailureException,Microsoft.SqlServer.M anagement.PowerShell.BackupSqlDatabaseCommand What is the correct way to execute Backup-SqlDatabase cmdlet remotely?

  • Event Tracing for Windows GUI

    - by Ian Boyd
    i want to view tracing events from the Event Tracing for Windows system. As far as i can tell the only client program that exists for connecting to providers is a command line tool that comes with the Microsoft Windows Device Driver Development Kit (DDK), e.g.: tracelog -start "NT Kernel Logger" -f krnl.etl -dpcisr -nodisk -nonet -b 1024 -min 4 -max 16 -ft 10 –UsePerfCounter ... tracelog –stop It then requires a separate command line tool to convert the generated log file into something usable, e.g.: trcerpt krnl.etl -report isrdpc.xml Has nobody come up with a Windows program (ala Performance Monitor, Process Monitor, Event Viewer) that lets me start tracing by pushing a "Go" button, let me see events, and i can stop it with a "Stop" button? Is there GUI for Event Tracing for Windows?

  • SSH - using keys works, but not in a script

    - by Garfonzo
    I'm kind of confused, I have set up public keys between two servers and it works great, sort of. It only works if I ssh manually from a terminal. When I put the ssh command into a python script, it asks me for a password to login. The script is using rsync to sync up a directory from one server to the other. manual ssh command that works, no password prompt, automatic login: ssh -p 1234 [email protected] In the Python script: rsync --ignore-existing --delete --stats --progress -rp -e "ssh -p 1234" [email protected]:/directory/ /other/directory/ What gives? (obviously, ssh details are fake)
