• Why isn't nrpe 'check_procs' finding my Passenger process?

  - by ethrbunny

  I'm trying to use check_procs from NRPE to find out whether Passenger is running on my server. It loads from httpd but appears separately. 32135 ? Sl 0:09 Passenger RackApp: /usr/share/puppet/rack/puppetmasterd 32589 ? Sl 0:01 Passenger AppPreloader: /usr/share/puppet/rack/puppetmasterd 32629 ? Sl 0:05 Passenger RackApp: /usr/share/puppet/rack/puppetmasterd 32751 ? Sl 0:05 Passenger RackApp: /usr/share/puppet/rack/puppetmasterd When I try to test it like so: check_procs -w 2: -c 3: -C Passenger It tells me there are 0 processes found. I see them - how do I get NRPE to count them?

• Static / Shared Helper Functions vs Built-In Methods

  - by Nathan

  This is a simple question but a design consideration that I often run across in my day to day development work. Lets say that you have a class that represents some kinds of collection. Public Class ModifiedCustomerOrders Public Property Orders as List(Of ModifiedOrders) End Class Within this class you do all kinds of important work, such as combining many different information sources and, eventually, build the Modified Customer Orders. Now, you have different processes that consume this class, each of which needs a slightly different slice of the ModifiedCustomerOrders items. To enable this, you want to add filtering functionality. How do you go about this? Do you: Add Filtering calls to the ModifiedCustomerOrders class so that you can say: MyOrdersClass.RemoveCanceledOrders() Create a Static / Shared "tooling" class that allows you to call: OrdersFilters.RemoveCanceledOrders(MyOrders) Create an extension method to accomplish the same feat as #2 but with less typing: MyOrders.RemoveCanceledOrders() Create a "Service" method that handles the getting of Orders as appropriate to the calling function, while using one of the previous approaches "under the hood". OrdersService.GetOrdersForProcessA() Others? I tend to prefer the tooling / extension method approaches as they make testing a little bit simpler. Although I dependency inject all my sourcing data into the ModifiedCustomerOrders, having it as part of the class makes it a little bit more complicated to test. Typically, I choose to use extension methods where I am doing parameterless transformations / filters. As they get more complex, I will move it into a static class instead. Thoughts on this approach? How would you approach it?

• JDeveloper News &ndash; Did You Know

  - by shay.shmeltzer

  There have been a few issues lately with access to blogs.oracle.com to write new messages – and as a result I’m a little behind on reporting the latest and greatest in JDeveloper. (I’m also unable to approve comments :-( ) But just in case you missed it here are a few note worthy things you should know: ADF Mobile Client went production – this is a solution that let you use ADF to develop on-device applications for mobile devices. You develop once and run on various devices (right now Blackberry and Windows Mobile with other platforms coming soon). For more information check out the ADF Mobile page on OTN. ADF Developer Certification goes production – you can now take the official test and get an official certification that you can include in your resume.Should be a must for any consultant looking to get ADF related gigs. Learn more about the ADF Certification Exam. ADF Vision Stencils Released – If you are looking for a quick way to draw prototypes of ADF screens you probably can’t get any faster and more accurate results than this. This is a set of Vision components that you can drag over and design a page visually. You can also set properties for components and do other advance things. You do need a license for Visio to use this, but the ADF stencils are free. We’ve been using these internally at Oracle for some time now and we thought the ADF community would enjoy these too. Download the ADF Visio Stencils here (and watch a youtube demo of how they work).

• How to setup a simple Ubuntu Server Tomcat cluster on VirtualBox for testing?

  - by Alex Pakka

  I am looking for a step by step instructions to setup at leat two (and later more) simple Ubuntu Virtual Core 12.10 Server VMs on Oracle VirtualBox under Windows 7 64bit. The test setup would be: Apache HTTP server on the Windows host acting as a Load Balancer. The result will be that going to http://localhost:8080 would balance between two nodes and prove session replication. Two lean, small footprint Ubuntu Server guest nodes with Java 7 and Tomcat 7. The intention is to help everyone doing High Availability / Load Balancing development and testing to create a reasonable environment on the local workstation or mainstream notebook in as little time as possible.

• How can I install from a 9.04 live USB/DVD?

  - by bstpierre

  I have a 9.04 (Jaunty) ISO burned to a USB stick; it appears to be a "live DVD". When I boot from it, I get a GRUB menu listing: Ubuntu, with Linux 2.6.35-generic (This matches the system currently installed on the HDD?) Ubuntu, with Linux 2.6.35-generic (recovery mode) Memory test Ubuntu 9.04, kernel 2.6.28-11-generic (on /dev/sda1) Ubuntu 9.04, kernel 2.6.28-11-generic (recovery mode) (on /dev/sda1) Ubuntu 9.04, memtest86+ (on /dev/sda1) When I select Ubuntu 9.04, kernel 2.6.28-11-generic (on /dev/sda1), I arrive at the desktop of a 9.04 system. I want to wipe the HDD clean and install 9.04. (Upgrading to something newer is not an option; this version is required by a legacy application.) How can I install from this live USB image? I vaguely remember some incantation that I should be able to use in the booted system, but my google-fu is broken at the moment. I'm comfortable with low-level commands, so if you want to recommend a more hard-core strategy, I'm willing to roll with it without requiring a ton of detail...

• ADF Logging In Deployed Apps

  - by Duncan Mills

  Harking back to my series on using the ADF logger and the related  ADF Insider Video, I've had a couple of queries this week about using the logger from Enterprise Manager (EM). I've alluded in those previous materials to how EM can be used but it's evident that folks need a little help.  So in this article, I'll quickly look at how you can switch logging on from the EM console for an application and how you can view the output.  Before we start I'm assuming that you have EM up and running, in my case I have a small test install of Fusion Middleware Patchset 5 with an ADF application deployed to a managed server. Step 1 - Select your Application In the EM navigator select the app you're interested in: At this point you can actually bring up the context ( right mouse click) menu to jump to the logging, but let's do it another way.  Step 2 - Open the Application Deployment Menu At the top of the screen, underneath the application name, you'll find a drop down menu which will take you to the options to view log messages and configure logging, thus: Step 3 - Set your Logging Levels  Just like the log configuration within JDeveloper, we can set up transient or permanent (not recommended!) loggers here. In this case I've filtered the class list down to just oracle.demo, and set the log level to config. You can now go away and do stuff in the app to generate log entries. Step 4 - View the Output  Again from the Application Deployment menu we can jump to the log viewer screen and, as I have here, start to filter down the logging output to the stuff you're interested in.  In this case I've filtered by module name. You'll notice here that you can again look at related log messages. Importantly, you'll also see the name of the log file that holds this message, so it you'd rather analyse the log in more detail offline, through the ODL log analyser in JDeveloper, then you can see which log to download.

• Multiple SSL on same IP [closed]

  - by kadourah

  Possible Duplicate: Multiple SSL domains on the same IP address and same port? I have the following situation: first domain: test.domain.com IP: 1.2.3.4 Port: 443 SSL: Purchased from godaddy and specific to that domain Works fine no issues. I would like to add another site: test2.domain.com IP: the same Port: can be different SSL: different since I can't use the SSL above because it's specific to the site above. Now, when I add the HTTPS binding to the second site with IP:Port combination it appears to always load the first SSL ignoring the second certificate. How can I add second SSL binding to the same IP using a "different" certificate? Can this be done?

• Is application-specific data required for good unit testing?

  - by stinkycheeseman

  I am writing unit tests for a fairly simple function that depends on a fairly complicated set of data. Essentially, the object I am manipulating represents a graph and this function determines whether to chart a line, bar, or pie chart based on the data that came back from the server. This is a simplified version, using jQuery: setDefaultChartType: function (graphObject) { var prop1 = graphObject.properties.key; var numCols = 0; $.each(graphObject.columns, function (colIndex, column) { numCols++; }); if ( numCols > 6 || ( prop1 > 1 && graphObject.data.length == 1) ) { graphObject.setChartType("line"); } else if ( numCols <=6 && prop1 == 1 ) { graphObject.setChartType("bar"); } else if ( numCols <=6 && prop1 > 1 ) { graphObject.setChartType("pie"); } } My question is, should I use mock data that is procured from the actual database? Or can I just fabricate data that fits the different cases? I'm afraid that fabricating data will not expose bugs arising from changes in the database, but on the other hand, it would require a lot more effort to keep the test data up-to-date that I'm not sure is necessary.

• Java application not starting in Tomcat, Plesk 9 server

  - by netagence

  Hi I have a Plesk 9.3 CentOS 5 server on which I installed the addon to have Tomcat functions. One application I have uploaded appears in the Plesk Tomcat user panel but with a yellow exclamation mark and the error "Actual status of the application does not correspond to the status retrieved from the database". The app therefore does not run, while other uploaded test .war applications do. The server runs Tomcat tomcat5.5.23-0jpp.7.el5_2.1 which matches the requirements for the required app according the the company that made it. While searching for the solution I could find all 3 uploaded .war applications in /usr/share/tomcat5/psa-wars/domainhere.com/ but they do not seem uncompressed there even though 2 of them run fine. Not enough Tomcat / Java knowlede to go on... Any idea to help me here ? Best regards.

• Personal Archive not Visible in Outlook

  - by Krypton2k

  I just added a second user to my Exchange 2010 box, it is in coexistence with exc2003. My account is already set up and working with a personal archive folder. The user I just set up however is unable to see the archive in Outlook. It is visible in OWA but not outlook. I have created a test profile on my PC with the users account and still no archive, if I jump back to my profile on the same box the archive is there so I know it is not an office versions issue. UPDATE: I have deleted all profiles from Outlook (one of which worked with the archive) now any new profiles including my own no longer show up. I think I have broken something In exchange. I get an auto discover certificate error which I am in the process of fixing. Perhaps the 2 problems are related. Also OWA on this server runs on a custom SSL port.

• Nameserver Problem

  - by Ruel

  I installed Virtualmin GPL with BIND, etc. I created a virtual host for my main domain, and edited the zone file, added the A records for the nameservers ns1.mydomain.com and ns2.mydomain.com. All looks good from the VPS, whenever I do a dig or nslookup, all seems fine, returning correct details. But when I test externally, there are no results. I tried several sites such as intodns, etc. It says my nameservers doesn't point to any IP. I have registered my nameservers with the appropriate IP in my registrar, and I even contacted support to verify this, and they told me that the registration was successful, but when they dig my nameservers, there's no ip address. I can also connect to my server IP's port 53. Also, I know that the DNS propagation is 24-48 hours. But there has to be some server that can return the correct results by now. Please lead me to the right direction, thanks.

• How do I troubleshoot a page not found error when configuring IIS6 Windows Server 2003? [Page Not Found]

  - by Vinicius Ottoni

  I have configured IIS6 in my windows server 2003 with this link: http://www.simongibson.com/intranet/iis6/ After that I create a new web site inside Web Sites directory. Inside the physical path I created an index.htm that has: <html> <body>Test</body> </html> But I got the following error: "The page cannot be found". When I put the same index file inside the Web Site Default physical path, it works. I configured the new web site with the link above using the IP configuration and without a Host Header.' What should I do to troubleshoot this or is there an obvious configuration error?

• Oracle EZConnect in Mediawiki

  - by raindog308

  Mediawiki supports Oracle and I'm trying to configure it in the installer. The installers says you can use EZConnect...something like: user/pass@//server.example.com/dbname or since the installer has fields elsewhere for user/pass server.example.com/dbname The installer includes a link to the EZConnect docs: http://docs.oracle.com/cd/E11882_01/network.112/e10836/naming.htm. All the examples in that doc include a forward slash. But every combination I've tried results in an error like this: Invalid database TNS "sever.example.com/service_name". Use only ASCII letters (a-z, A-Z), numbers (0-9), underscores (_) and dots (.). I can't find any examples of EZConnect that don't include a forward slash. That error is from Mediawiki, not Oracle. I'm tailing the listener log and there is no connection made - Medaiwiki is returning an error without trying to connect. I'm using php OCI8 with the Oracle instant client. I don't have a tnsnames.ora setup for this client - which is kind of the point of EZConnect. I did write a test php script that connects via oci_connect just fine. Has anyone configured Mediawiki to use Oracle with EZConnect? If so, what did you use in the installer?

• Windows 8: User profile service service failed the login. User Profile can not be loaded

  - by Ryanmt

  I removed accounts that were hosted on a separate drive before upgrading to windows 8 from 7 yesterday. However, now I get the User profile service service failed the login. User Profile can not be loaded. error whenever I try to access any new account. I've attempted it: from safe mode (suggestions here ) net user test \ADD Editing the permissions on the %sysdrive%\Users\Default folder to ensure it is readable Every attempt is met with the same error. Additionally, I do not see any new entries created in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList registry entry. I'm not sure I understand why a failed user creation wouldn't trigger an error... but that seems to be what is happening here.

• SSL issues with puppet agent at openSUSE

  - by Roman Grazhdan

  I have a master running at my vps, and it has a simple helloworld manifest which works fine with any ubuntu machine I have. It connects, exchanges keys and creates test file allright, so I'm sure it's not server issue. The agent which is running at a virtual machine with openSUSE says: err: Could not request certificate: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed. This is often because the time is out of sync on the server or client I believe it's probably a broken or missing lib, since the package is not built very accurately - it wouldn't start out of the box because of wrong path to lockfile, for example. So how do I figure out what exactly is wrong here? The time is allright, I've checked it. I probably could do without SSL if it's possible, since that SUSE machines are just for training, but it's the last opportunity.

• Shell script to read value from a file and compare it to another one

  - by maneeshshetty

  I have a C program which puts one unique value inside a test file (it would be a two digit number). Now I want to run a shell script to read that number and then compare with my required number (e.g. 40). The comparison should deliver "equal to" or "greater". For example: The output of the C program is written into the file called c.txt with the value 36, and I want to compare it with the number 40. So I want that comparison to be "equal to" or "greater" and then echo the value "equal" or "greater".

• Cisco: changing VTP mode server/client to transparent

  - by J. Smith

  I have around 40 L2 switches (2960, 3560, 3500, 3750) running in VTP client mode and one L3 switch (6500) running in VTP server mode, all connected together. I would like to switch everything in VTP transparent mode without any interruption of service. I've already test on a poc version with 3 switches (Catalyst 2950, 3560 and 3750). Using serial and SSH connection, it is seems working but i'm not sure it is enough representative compare to the real network. Knowing that the VTP Pruning is enabled, I am wondering what would be the best procedure to proceed the changement. I've read that we could lost connection by keeping it enabled. Should I change the server or clients first? Is it important to change the VTP domain and VTP Pruning parameters?

• Crackling sound from microphone recently, in 13.04

  - by Patrig Droumaguet

  I use 13.04 since the release and I use Skype which was working well. But recently I've had remarks saying my voice was "crackling", even if the voice from my interlocutor was perfect. Making a test with Audacity and Cheese, I've seen that every recorded sound (with the front microphone of my laptop or a jack microphone) was crackling. It's not really like saturating, the sound has a lot of annoying pops. I've tried to check the settings, they were still on PulseAudio. I've even tried the extreme solution : re-installing Ubuntu (because initially it was working)… with the same problem. If I boot on Windows (dual-boot) I have no problem (so it's not physical). If anyone could help :) My laptop is a HP dv6-6165sf. The sound card is a "IDT 92HD81B1X5" (with BeatsAudio). Thanks a lot ! New tests - july 6th Hi again, I've tried editing /etc/pulse/default.pa with these three settings : load-module module-udev-detect use_ucm=0 tsched=0 load-module module-udev-detect tsched=0 load-module module-udev-detect use_ucm=0 The three of them don't change anything, except the last one (which was by default) which makes Audacity record without any crackling sound. But in Skype, Cheese and Kazam, the sound is crackling… I've installed again Ubuntu 13.04 (from scratch, deleting everything from /home), and I've updated it. The microphone is still cracking. Thanks for your help !

• recovering raid 0 hard disk

  - by Hiawatha

  I bumped to a huge (for me) problem. I was running dual boot system (win 7 / linux) and at some point I decided to test fedora ( I am new in Linux ). My hard disk conf: 3 hard disks each 1 TB, 2 set to raid 0 with windows running on it and 1 for linux. After installing it from live usb I found out that windows 7 is not in grub anymore and while booting shows raid error. I installed back Ubuntu and ran Disk Utility and checked now I have one disks (raid 0) failed (READ) error. First has 5 bad sectors and second has 1 bad sector. And now I dont know what to do and how to repair. further I dont know which data i could provide to get help. I tried ntfsfix and got this output: Mounting volume... NTFS signature is missing. FAILED Attempting to correct errors... NTFS signature is missing. FAILED Failed to startup volume: Invalid argument NTFS signature is missing. Trying the alternate boot sector Unrecoverable error Volume is corrupt. You should run chkdsk. #sudo ntfs-3g -o force,rw /dev/sdb /media/windows NTFS signature is missing. Failed to mount '/dev/sdb': Invalid argument The device '/dev/sdb' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
