• Cannot run SSH or send commands to /etc/init.d/ssh

  - by ThinkBohemian

  When I attempt to execute any commands such as /etc/init.d/ssh restart or /etc/init.d/ssh start, I get no output. It just goes to the next command line (Ubuntu Hardy). I can even pass in junk parameters such as /etc/init.d/ssh asldkfjalskfdj and i get no warnings or error messages, it just goes to the next line. I can check in my processes: lsof -i :22 and don't see my ssh process. I also don't see my SSH process when i run: netstat -na --inet Any troubleshooting suggestions?

• Mac OS X Server add server user

  - by Meltemi

  What's the recommended way to add a user to Mac OS X Server that doesn't need all the hoopla associated with Workgroup Manager? There are many users pre-configured in Mac OS X Server (www, root, ldapadmin, etc.) that don't have "Full Name" or mail accounts, etc. I'd like to create a 'svn' user to be the owner of our Subversion Repository as per this tutorial: If you've decided to use either Apache or stock svnserve, create a single svn user on your system and run the server process as that user. Be sure to make the repository directory wholly owned by the svn user as well. From a security point of view, this keeps the repository data nicely siloed and protected by operating system filesystem permissions, changeable by only the Sub- version server process itself. Wondering if there's a way outside of WorkgroupManager and OpenDirectory as this account will be entirely server based. Is this still sound advice under OS X Server? If so what's the easiest way to create the user (Mac OS X Server doesn't seem to respond to useradd).

• Annotate source code with diagrams as comments

  - by Steven Lu

  I write a lot of (primarily c++ and javascript) code that touches upon computational geometry and graphics and those kinds of topics, so I have found that visual diagrams have been an indispensable part of the process of solving problems. I have determined just now that "oh, wouldn't it just be fantastic if I could somehow attach a hand-drawn diagram to a piece of code as a comment", and this would allow me to come back to something I worked on, days, weeks, months earlier and far more quickly re-grok my algorithms. As a visual learner, I feel like this has the potential to improve my productivity with almost every type of programming because simple diagrams can help with understanding and reasoning about any type of non-trivial data structure. Graphs for example. During graph theory class at university I had only ever been able to truly comprehend the graph relationships that I could actually draw diagrammatical representations of. So... No IDE to my knowledge lets you save a picture as a comment to code. My thinking was that I or someone else could come up with some reasonably easy-to-use tool that can convert an image into a base64 binary string which I can then insert into my code. If the conversion/insertion process can be streamlined enough it would allow a far better connection between the diagram and the actual code, so I no longer need to chronographically search through my notebooks. Even more awesome: plugins for the IDEs to automatically parse out and display the image. There is absolutely nothing difficult about this from a theoretical point of view. My guess is that it would take some extra time for me to actually figure out how to extend my favorite IDEs and maintain these plugins, so I'd be totally happy with a sort of code post-processor which would do the same parsing out and rendering of the images and show them side by side with the code, inside of a browser or something. Since I'm a javascript programmer by trade. What do people think? Would anyone pay for this? I would.

• Using Lighttpd: apache prox or direct connection?

  - by Halfgaar

  Hi, I'm optimizing a site by using lighttpd for the static media. I've found that a recommended solution is to use Apache Proxy to point to the lighttpd server. But, does that use up an Apache thread/process per request? In my setup, I've noticed that all my processes are used up, even though they aren't doing anything, CPU wise. To free up apache processes, I've configured lighttpd and the amount of processes needed is lowered significantly, Munin shows. However, I've set it up to connect directly to lighty, to prevent apache workers from server static media. My question is: when using Apache Proxy, does that also use up a process/worker?

• Windows pysical server provisioning question with HPSA 7.8

  - by warren

  I have a physical server that I am trying to provision Windows to. At 58% of the way through copying files form the Core to the target server, the process hangs with either a samba time-out or an error indicating that %path%\system32\ntoskrnl.exe is missing or corrupt. I can build a VM on the same subnet with the same media (merely a different profile to catch the different unattend.txt file) with no issues. I can also provision RHEL5 to this server with no issues. The buildmgr logs indicate that eventually the job is timing-out. Samba logs show that connections are made, and then eventually closed - about the time that the build process times-out. Any ideas on where to look next?

• Doesn't installing "All locales" install necessary fonts too?

  - by its_me

  I recently noticed that my browsers rendered blank text (or invisible text?) on some websites in foreign languages, like Chinese. inside.com.tw, for example. Later I learnt that by default Debian only installs one locale (the one you choose during the installation process), and others need to be installed manually. So, I ran the command: # dpkg-reconfigure locales And selected All locales from the options screen that followed, and proceeded with the rest of the process, which also includes changing the default locale (which I set to en_US.UTF-8). Then I restarted my system. I still can't read the website that I mentioned earlier (inside.com.tw). Most of the text is blank, i.e. invisible. With the page translated by Chrome to my default language (en_US), the text is visible; BUT not in the original language. Why is this happening? Does this mean that installing locales isn't actually necessary, and all I have to do is install the fonts for all supported languages? If so, how do I install all the fonts necessary for All locales? UPDATE: An easy fix is to install the unifont package which adds support for all Unicode 5.1 characters. But the rendering is of very bad quality. So, how I install all font packages? I notice that there are three sets, ones starting with fonts-*, another with xfonts-*, and ttf-*? Which set should I exactly go with, and how do I install that set of fonts. Looking for a knowledgeable solution.

• silent failure while creating odbc data source

  - by Peter

  I just got really confused trying to create an ODBC data source in Windows 2003 R2. I can create a connection to my chosen server (a MS SQL Server) on the "user DSN" tab, but when I try to do the same thing on the "system DSN tab", the process fails but without an error message. I am able to connect to the target database fine at the end of configuring a new data source, but when I click OK, the data source just isn't there. No error message, no sign that anything went amiss, other than the lack of a new data source. Very annoying, as I had to repeat the process a few times to make sure I wasn't crazy. Anybody got any hints? I suspect it is a permission problem of some sort but since there is no error message, I don't know where to start.

• Difference between Detach/Attach and Restore/BackUp a DB

  - by SAMIR BHOGAYTA

  Transact-SQL BACKUP/RESTORE is the normal method for database backup and recovery. Databases can be backed up while online. The backup file size is usually smaller than the database files since only used pages are backed up. Also, in the FULL or BULK_LOGGED recovery model, you can reduce potential data loss by performing transaction log backups. Detaching a database removes the database from SQL Server while leaving the physical database files intact. This allows you to rename or move the physical files and then re-attach. Although one could perform cold backups using this technique, detach/attach isn't really intended to be used as a backup/recovery process. Commonly it is recommended that you use BACKUP/RESTORE for disaster recovery (DR) scenario and copying data from one location to another. But this is not absolute, sometimes for a very large database, if you want to move it from one location to another, backup/restore process may spend a lot of time which you do not like, in this case, detaching/attaching a database is a better way since you can attach a workable database very fast. But you need to aware that detaching a database will bring it offline for a short time and detaching/attaching does not provide DR function. For more information about detaching and attaching databases, you can refer to: Detaching and Attaching Databases http://technet.microsoft.com/en-us/library/ms190794.aspx

• JSR Updates and Inactive JSRs

  - by heathervc

   The following JSRs have made progress in the JCP program this week: JSR 342, Java Platform, Enterprise Edition 7 (Java EE 7) Specification, has posted an Early Draft 2 Review.  This review closes 30 November. JSR 338, Java Persistence 2.1, has posted an Early Draft 2 Review.  This review closes 30 November.  JSR 346, Contexts and Dependency Injection for Java, EE 1.1, has posted a Public Review.  This review closes 3 December.  JSR 352, Batch Applications for the Java Platform, has posted a Public Review.  This review closes 3 December. Inactive JSRs: In 2008, we initiated an effort to identify JSRs that had not continued to make progress in the JCP program.  We have reported on this topic since that time at JCP Executive Committee Meetings. The term 'Inactive JSRs' was introduced, and a process was developed with the guidance of the EC to reduce the number of Inactive JSRs  (reduced from over 60 to 2 JSRs) through either moving to the next JSR stage or being Withdrawn or declared Dormant.  This process has been formalized in JCP 2.8 and above, with the introduction of JSR deadlines.  The JSRs which were put to a Dormancy Ballot in September 2012  have been approved by the EC and are now declared Dormant.  You can view the results of the JSR Voting on JCP.org.  The latest Inactive JSRs report is available as part of the September 2012 JCP EC Face-to-Face Meeting Materials.

• One of my apache processes is huge - how can I find out why?

  - by Malcolm Box

  I'm running Apache 2.2.12 with mod_wsgi, hosting a Django site. Most of the apache child processes weigh in at about 125MB RSS, but occasionally I see one child balloon to 1GB RSS. At this point there's usually 1 huge process (1GB), a couple of large ones (500MB) and the rest are still ~125MB. These are the mod_wsgi daemon processes. I've tried using memory leak tracing in Python to see if it's the Django code, and I see no leaks. Looking in the logs doesn't show any particularly strange requests. I'm stumped on how to figure out what's causing this - any ideas? Also, any workaround ways to kill the large apache process when it gets too big, without bringing apache down? Some more details: Not using mod_php Using pre-fork

• On boot firmware request for intel GMA 3100 chipset timing out

  - by Yannick M.

  I am currently in the process of installing a Gentoo linux box with a Vanilla 2.6.29-r5 kernel with gentoo-xen-kernel patches in order to run the Xen Hypervisor. After rebooting with the new kernel, the booting process seemed to hang on: [ 0.863005] platform microcode: firmware: requesting intel-ucode/06-0f-07 [ 60.863442] Microcode Update Driver: v2.00-xen <[email protected]>, Peter Oruba Apparently the firmware request times out after 60 seconds (/sys/class/firmware/timeout) and booting just continues. I have done some research and have found that on RHEL-4 this problem was related to the mount of /sys changed and the firmware.agent hotplug script couldn't parse the line correctly. However I am having some difficulty tracking down how to fix this on Gentoo. Any and all ideas are greatly appreciated! Thanks

• US GAAP and IFRS Convergence May Be Delayed Even More

  - by Theresa Hickman

  Yesterday, on March 10, the Financial Accounting Standards Board (FASB) met to discuss the changes in financial statement presentation. Over the last six months, the FASB and IASB have been working feverishly to converge US GAAP and IFRS standards to meet the 2011 deadline. In March alone, the standards-setters met eight times. Many people fear that this accelerated pace is compromising the quality of the end product and that maybe they should slow down and do their due diligence. According to WG&L Accounting & Compliance Alert Checkpoint 3/10/2010, (which requires a subscription to view the full article) "Some statement preparers and investors who advise the FASB believe that the process would be better served if it was slowed down so that more attention could be paid to quality." "Should 2011 be looked at as a line in the sand?" asked Joan Amble, executive vice president and corporate comptroller for American Express Co. "We don't think that due process should be compromised for the due date," concurred Lewis Dulitz, vice president of accounting policies and research for medical products supplier Covidien plc. I personally have mixed emotions about this. On one hand, I have been growing impatient with how slow the US has jumped on the IFRS band wagon. On the other hand, being the conservative that I am and knowing this convergence will be costly and disruptive to businesses, I would prefer to be safe than sorry and get it right the first time.

• Ganglia and how it communicates

  - by MikeKulls

  I'm a little confused about how Ganglia sends information around and have found conflicting information on the web. I would have thought that the gmond process would either send info to gmetad at a regular interval or gmetad would request info from the various instances of gmond. At least one online article states this is how it works but from what I understand this is incorrect. It appears that you configure all gmond processes to send their info to a central gmond process and gmetad will request info from that central gmond. Is that correct? In my case I have 6 servers sending their information to 1 central server. If I set gmetad to get it's information from the central server then I get information from all 6 servers, all good.. Their weird thing is that if I point gmetad to one of the 6 servers then I still get info from all 6 servers. How is it that server 1 in my cluster if getting stats from all the other servers?

• Online Media Daily: Oracle Takes Social Marketing Seriously

  - by Richard Lefebvre

  In the article published on Nov 12, 2012 and titled "Oracle Integrates Social Marketing Into Enterprise To Gain Marketing Revs," Online Media Daily explores Oracle's approach to social marketing. The publication says that Oracle is focused on showing marketers how to integrate social data into corporate business processes and how to "socialize" the corporate world. The article goes on to state:"Enterprise software companies like Oracle, SAP, IBM, Salesforce and Microsoft have been slowly building up an expertise in social marketing to integrate the data into traditional enterprise resource planning, and customer relationship management tools into social marketing tools.   Enterprise software companies like Oracle, SAP, IBM, Salesforce and Microsoft have been slowly building up an expertise in social marketing to integrate the data into traditional enterprise resource planning, and customer relationship management tools into social marketing tools.    Read more: http://www.mediapost.com/publications/article/187096/oracle-integrates-social-marketing-into-enterprise.html#ixzz2CPMZ1w3D Meg Bear, VP of cloud social platform at Oracle, sees the integration with ERP systems as a differentiator for the company. Oracle Social Relationship Management launched last month. It integrates social data into traditional enterprise applications like Oracle Fusion Marketing, Oracle Fusion Sales Catalog, Oracle ATG Web Commerce and Oracle ERP." The post goes on to quote a Forrester analyst stating the following:""There's room for any process-driven application to run more efficiently, especially if they're socially enabled," said Rob Koplowitz, VP and principal analyst at Forrester Research. "It takes the human part of the process not generally captured today to provide better access to content, information and collective actions." Koplowitz said several acquisitions support Oracle's long-term vision: to layer social on top of other enterprise apps, like its ERP platform." With many great acquisitions under our belt and organically grown social tools, the market recognizes that Oracle is poised to seize the moment in socially enabled business apps.

  On the main production server, the IIS worker process crashes sometimes. From the event viewer I get the following information. Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8 Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319 Exception code: 0xe053534f Fault offset: 0x0000b9bc Faulting process id: 0x%9 Faulting application start time: 0x%10 Faulting application path: %11 Faulting module path: %12 Report Id: %13 This happens randomly on the prod server and I have not been able to recreate this crash anywhere else. This was happening on IIS 6, and we recently moved to Windows Server 2008 and IIS 7.5 and the crash happens there as well. How to go about finding the root cause of this?

• Does waterfall require code complete before QA steps in?

  - by P.Brian.Mackey

  The process used at a certain company consists of: Create a layout according to some designs made in a web page design tool. (CSS, html) Requirements come in with "functional requirements". These consist of 100's of lines of business directions. E.G. Create a Table on page X. Column1 has numeric data. Column1 is the client code. Column2 is a string...etc. Write code to meet all functional requirements. When all code is checked in, send to QA (which is the BA that wrote the requirements) for inspection, bug finds and change requests. Punt back to developer with a list of X bugs and Y change requests. While bug finds or change requests 0 go to step 4. The agile development environments I have worked in allow, if not demand, early QA inspection and early user acceptance. So, pieces of the program can be refined and redefined before the entire application is in place. Not only that, but the process leaves little room for error or people changing their minds. Instead, those "change requests" come in at the last stage when they do the most damage. And being that a bug-fix's cost increases over time, this is a costly way to write code. I am no waterfall expert. As described, is this waterfall being mishandled in some way? How does waterfall address my concerns?

• MIA

  - by Robert May

  So, I’ve been missing in action on this blog for quite some time.  I need to rectify that. Part of the reason I’ve been absent is because I haven’t be able to talk about what I’m working on.  A former client watches my blog rather closely, and although we accomplished many good things together, their culture is such that they really don’t like people to freely express their thoughts (you’ll note my blog posts stopped rather abruptly).  I learned some really important lessons about Agile in the last 3 years, and I think its worthwhile to talk about them.  Sometimes things worked really well, sometimes, they failed failed.  Sometimes that failure was me, sometimes it wasn’t. I understand Agile better now, and hopefully, what I have to say will guide others through this process and help others understand Agile better. One thing that I’ve learned is that MANY companies that say they are doing Agile are NOT really doing Agile.  To often, they pick the things they like and don’t follow the process long enough to know what rules they can break, and which ones they shouldn’t.  This is probably the primary reason why Agile fails. So, expect more posts, especially as I’m flying coast to coast. :)

• Running scheduled web scripts in a Windows Server environment

  - by Dan Murfitt

  I'm trying to get a scheduled web script running on a Windows Server and so far the only way I've managed to automate this process is by using the Task Scheduler to open Internet Explorer with the web address as a parameter. I then need to create a separate task to run just after this task to close Internet Explorer (otherwise the task doesn't complete). Is there a better way of doing this? I've also managed to run the script by calling the web address through a Telnet connection to the web server (GET /web/address/here) but I haven't found a way of automating this process on a scheduled basis. Any ideas appreciated

• Camunda BPM 7.0 on WebLogic 12c

  - by JuergenKress

  If we go on tour together with Oracle I think we have to have camunda BPM running on the Oracle WebLogic application server 12c (WLS in short). And one of our enterprise customers asked - so I invested a Sunday and got it running (okay - to be honest - I needed quite some help from our Java EE server guru Christian). In this blog post I give a step by step description how run camunda BPM on WLS. Please note that this is not an official distribution (which would include a sophisticated QA, a comprehensive documentation and a proper distribution) - it was my personal hobby. And I did not fire the whole test suite agains WLS - so there might be some issues. We will do the real productization as soon as we have a customer for it (let us know if this is interesting for you). Necessary steps After installing and starting up WLS (I used the zip distribution of WLS 12c by the way) you have to do: Add a datasource Add shared libraries Add a resource adapter (for the Job Executor using a proper WorkManager from WLS) Add an EAR starting up one process engine Add a WAR file containing the REST API Add other WAR files (e.g. cockpit) and your own process applications Actually that sounds more work to do than it is ;-) So let's get started: Add a datasource Add a datasource via the Administration Console (or any other convenient way on WLS - I should admit that personally I am not the WLS expert). Make sure that you target it on your server - this is not done by default: Read the full article here.

• Converting gzip files to bzip2 efficiently

  - by sundar

  I have a bunch of gzip files that I have to convert to bzip2 every now and then. Currently, I'm using a shell script that simply 'gunzip's each file and then 'bzip2's it. Though this works, it takes a lot of time to complete. Is it possible to make this process more efficient? I'm ready to take a dive and look into gunzip and bzip2's source codes if necessary, but I just want to be sure of the payoff. Is there any hope of improving the efficiency of the process?
