  • Brownfield Support for OVMSS

    - by Owen Allen
    The area of virtualization saw quite a few enhancements with version 12.2. There's one particular virtualization enhancement that can make a big difference for a lot of people: support for brownfield Oracle VM Servers for SPARC. Brownfield refers to Oracle VM Servers for SPARC that were created outside of Ops Center. In older versions of Ops Center, you couldn't really do anything with them - Ops Center could only manage OVM Servers that it created. If you had OVM Servers outside of Ops Center, you'd have to recreate them if you wanted to manage them. In 12.2, though, this problem is cleared up. You can discover and manage OVM Servers for SPARC that you created outside of Ops Center, so long as the LDom Manager is running. When you discover the control domain, all of the logical domains are automatically discovered and managed and appear under the control domain in the Asset tree. If you want to use server pools and migrate the logical domains to a different Oracle VM Server for SPARC system, you'll need to move the metadata to a shared library and use shared Fibre Channel or iSCSI LUNs for the guest domain storage and add the server to a server pool. See the Oracle VM Server for SPARC chapter for more information.

  • How to set individual NTFS partitions permissions behaviour for each user account?

    - by ryniek
    I have two NTFS partitions (DOWNLOADS for downloaded files and VM for my VirtualBox .vdi file) for which i must have full permissions for my allday use account. They should be also automounting when i login to this account. But i've also set Guest account for guests. For Guest account, i want make VM partition fully disabled and invisible (and thus it mustn't automount) but DOWNLOADS partition should be shared with limited privileges with Guest account. Editing fstab i'm able to share DOWNLOADS partition with Guest on limited privileges but VM can be only set to limited and have disabled automounting - so guest can't mount it but it still can be seen in Nautilus, plus I must always mount it manually when i login to allday account. Is there some trick to make what i want? Here's my fstab config: # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 #Entry for /dev/sda1 : UUID=35e66658-5ee9-40cf-bf56-8204959e3df0 / xfs defaults 01 #Entry for /dev/sda2 : UUID=26c714cf-4236-45e7-9c46-cfcf91a215ae /home xfs defaults 02 #Entry for /dev/sda5 : UUID=1315BCB027C44639 /media/DOWNLOADS ntfs-3g auto,uid=1000,gid=1000,umask=0022,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda6 : UUID=60FF39EB72B72264 /media/VM ntfs noauto,uid=1000,gid=1000,umask=0077,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda7 : UUID=c52411f5-105c-45d1-971f-412f962c350e none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 Thanks

  • Purpose oriented user accounts on a single desktop?

    - by dd_dent
    Starting point: I currently do development for Dynamics Ax, Android and an occasional dabble with Wordpress and Python. Soon, I'll start a project involving setting up WP on Google Apps Engine. Everything is, and should continue to, run from the same PC (running Linux Mint). Issue: I'm afraid of botching/bogging down my setup due to tinkering/installing multiple runtimes/IDE's/SDK's/Services, so I was thinking of using multiple users, each purposed to handle the task at hand (web, Android etc) and making each user as inert as possible to one another. What I need to know is the following: Is this a good/feasible practice? The second closest thing to this using remote desktops connections, either to computers or to VM's, which I'd rather avoid. What about switching users? Can it be made seamless? Anything else I should know? Update and clarification regarding VM's and whatnot: The reason I wish to avoid resorting to VM's is that I dislike the performance impact and sluggishness associated with it. I also suspect it might add a layer of complexity I wish to avoid. This answer by Wyatt is interesting but I think it's only partly suited for requirements (web development for example). Also, in reference to the point made about system wide installs, there is a level compromise I should accept as experessed by this for example. This option suggested by 9000 is also enticing (more than VM's actually) and by no means do I intend to "Juggle" JVMs and whatnot, partly due to the reason mentioned before. Regarding complexity, I agree and would consider what was said, only from my experience I tend to pollute my work environment with SDKs and runtimes I tried and discarded, which would occasionally leave leftovers which cause issues throught the session. What I really want is a set of well defined, non virtualized sessions from which I can choose at my leisure and be mostly (to a reasonable extent) safe from affecting each session from the other. And what I'm really asking is if and how can this be done using user accounts.

  • One of my VMs went boom using Virtual Box and how it got fixed

    - by Enrique Lima
    I am running an HP Envy 15, 16GB and 500GB (7200 RPM) Hard drive. Had a VM configured from another environment, created the virtual machine config file on Virtual Box, everything seemed ok. Fired it up, and it was  s   l   o   w, it took close to 10 minutes for it to load, and about 5 more to see Windows was in the process of loading before the BSOD.  Thought, maybe, just maybe it will not happen again … oh was I wrong. Frustration had already hit an all time high with this configuration and the number of issues I’ve had. How I did the troubleshooting … The best thing to do (IMO) is to step back, and gather your tools to debug this situation. Tools:  Virtual Box command line tools, Windows Debug. Virtual Box comes with a pretty good set of tools to examine, migrate and overall tasks to deal with VMs. The firs step:  use VBoxManage to prevent the VM from rebooting after the error to get enough time to really dig into the BSOD issue. Command used:   VBoxManage setextradata VMNAME "VBoxInternal/PDM/HaltOnReset" 1 Once this was done, the error reported was an “Inaccessible boot device” coming from a “Stop – 7B” type of error on the BSOD. The issue I had with this, my VM was configured to use a virtual SATA controller, and thought Windows 2008 R2 would handle this fine … again wrong!  Because the integration tools from the other product where wanting to take effect that was throwing everything off. The fix The fix was almost handed to me, edited the configuration for the VM, removed the SATA controller from it, added the virtual hard drive under an IDE controller, boot up and voilà … it works! I was then able to install the Virtual Box guest tools and such, but have decided to favor “keep on working” over “let’s try SATA again”

  • User Group Meeting Summary - April 2010

    - by Michael Stephenson
    Thanks to everyone who could make it to what turned out to be an excellent SBUG event.  First some thanks to:  Speakers: Anthony Ross and Elton Stoneman Host: The various people at Hitachi who helped to organise and arrange the venue.   Session 1 - Getting up and running with Windows Mobile and the Windows Azure Service Bus In this session Anthony discussed some considerations for using Windows Mobile and the Windows Azure Service Bus from a real-world project which Hitachi have been working on with EasyJet.  Anthony also walked through a simplified demo of the concepts which applied on the project.   In addition to the slides and demo it was also very interesting to discuss with the guys involved on this project to hear about their real experiences developing with the Azure Service Bus and some of the limitations they have had to work around in Windows Mobiles ability to interact with the service bus.   On the back of this session we will look to do some further activities around this topic and the guys offered to share their wish list of features for both Windows Mobile and Windows Azure which we will look to share for user group discussion.   Another interesting point was the cost aspects of using the ISB which were very low.   Session 2 - The Enterprise Cache In the second session Elton used a few slides which are based around one of his customer scenario's where they are looking into the concept of an Enterprise Cache within the organisation.  Elton discusses this concept and also a codeplex project he is putting together which allows you to take advantage of a cache with various providers such as Memcached, AppFabric Caching and Ncache.   Following the presentation it was interesting to hear peoples thoughts on various aspects such as the enterprise cache versus an out of process application cache.  Also there was interesting discussion around how people would like to search the cache in the future.   We will again look to put together some follow-up activity on this   Meeting Summary Following the meeting all slide decks are saved in the skydrive location where we keep content from all meetings: http://cid-40015ea59a1307c8.skydrive.live.com/browse.aspx/.Public/SBUG/SBUG%20Meetings/2010%20April   Remember that the details of all previous events are on the following page. http://uksoabpm.org/Events.aspx   Competition We had three copies of the Windows Identity Foundation Patterns and Practices book that were raffles on the night, it would be great to hear any feedback on the book from those who won it.   Recording The user group meeting was recorded and we will look to make this available online sometime soon.   UG Business The following things were discussed as general UG topics:   We will change the name of the user group to the UK Connected Systems User Group to we are more inline with other user groups who cover similar topics and we believe this will help us to attract more members.  The content or focus of the user group is not expected to change.   The next meeting is 26th May and can be registered at the following link: http://sbugmay2010.eventbrite.com/

  • Cloud Computing = Elasticity * Availability

    - by Herve Roggero
    What is cloud computing? Is hosting the same thing as cloud computing? Are you running a cloud if you already use virtual machines? What is the difference between Infrastructure as a Service (IaaS) and a cloud provider? And the list goes on… these questions keep coming up and all try to fundamentally explain what “cloud” means relative to other concepts. At the risk of over simplification, answering these questions becomes simpler once you understand the primary foundations of cloud computing: Elasticity and Availability.   Elasticity The basic value proposition of cloud computing is to pay as you go, and to pay for what you use. This implies that an application can expand and contract on demand, across all its tiers (presentation layer, services, database, security…).  This also implies that application components can grow independently from each other. So if you need more storage for your database, you should be able to grow that tier without affecting, reconfiguring or changing the other tiers. Basically, cloud applications behave like a sponge; when you add water to a sponge, it grows in size; in the application world, the more customers you add, the more it grows. Pure IaaS providers will provide certain benefits, specifically in terms of operating costs, but an IaaS provider will not help you in making your applications elastic; neither will Virtual Machines. The smallest elasticity unit of an IaaS provider and a Virtual Machine environment is a server (physical or virtual). While adding servers in a datacenter helps in achieving scale, it is hardly enough. The application has yet to use this hardware.  If the process of adding computing resources is not transparent to the application, the application is not elastic.   As you can see from the above description, designing for the cloud is not about more servers; it is about designing an application for elasticity regardless of the underlying server farm.   Availability The fact of the matter is that making applications highly available is hard. It requires highly specialized tools and trained staff. On top of it, it's expensive. Many companies are required to run multiple data centers due to high availability requirements. In some organizations, some data centers are simply on standby, waiting to be used in a case of a failover. Other organizations are able to achieve a certain level of success with active/active data centers, in which all available data centers serve incoming user requests. While achieving high availability for services is relatively simple, establishing a highly available database farm is far more complex. In fact it is so complex that many companies establish yearly tests to validate failover procedures.   To a certain degree certain IaaS provides can assist with complex disaster recovery planning and setting up data centers that can achieve successful failover. However the burden is still on the corporation to manage and maintain such an environment, including regular hardware and software upgrades. Cloud computing on the other hand removes most of the disaster recovery requirements by hiding many of the underlying complexities.   Cloud Providers A cloud provider is an infrastructure provider offering additional tools to achieve application elasticity and availability that are not usually available on-premise. For example Microsoft Azure provides a simple configuration screen that makes it possible to run 1 or 100 web sites by clicking a button or two on a screen (simplifying provisioning), and soon SQL Azure will offer Data Federation to allow database sharding (which allows you to scale the database tier seamlessly and automatically). Other cloud providers offer certain features that are not available on-premise as well, such as the Amazon SC3 (Simple Storage Service) which gives you virtually unlimited storage capabilities for simple data stores, which is somewhat equivalent to the Microsoft Azure Table offering (offering a server-independent data storage model). Unlike IaaS providers, cloud providers give you the necessary tools to adopt elasticity as part of your application architecture.    Some cloud providers offer built-in high availability that get you out of the business of configuring clustered solutions, or running multiple data centers. Some cloud providers will give you more control (which puts some of that burden back on the customers' shoulder) and others will tend to make high availability totally transparent. For example, SQL Azure provides high availability automatically which would be very difficult to achieve (and very costly) on premise.   Keep in mind that each cloud provider has its strengths and weaknesses; some are better at achieving transparent scalability and server independence than others.    Not for Everyone Note however that it is up to you to leverage the elasticity capabilities of a cloud provider, as discussed previously; if you build a website that does not need to scale, for which elasticity is not important, then you can use a traditional host provider unless you also need high availability. Leveraging the technologies of cloud providers can be difficult and can become a journey for companies that build their solutions in a scale up fashion. Cloud computing promises to address cost containment and scalability of applications with built-in high availability. If your application does not need to scale or you do not need high availability, then cloud computing may not be for you. In fact, you may pay a premium to run your applications with cloud providers due to the underlying technologies built specifically for scalability and availability requirements. And as such, the cloud is not for everyone.   Consistent Customer Experience, Predictable Cost With all its complexities, buzz and foggy definition, cloud computing boils down to a simple objective: consistent customer experience at a predictable cost.  The objective of a cloud solution is to provide the same user experience to your last customer than the first, while keeping your operating costs directly proportional to the number of customers you have. Making your applications elastic and highly available across all its tiers, with as much automation as possible, achieves the first objective of a consistent customer experience. And the ability to expand and contract the infrastructure footprint of your application dynamically achieves the cost containment objectives.     Herve Roggero is a SQL Azure MVP and co-author of Pro SQL Azure (APress).  He is the co-founder of Blue Syntax Consulting (www.bluesyntax.net), a company focusing on cloud computing technologies helping customers understand and adopt cloud computing technologies.

  • Cloud Computing: Start with the problem

    - by BuckWoody
    At one point in my life I would build my own computing system for home use. I wanted a particular video card, a certain set of drives, and a lot of memory. Not only could I not find those things in a vendor’s pre-built computer, but those were more expensive – by a lot. As time moved on and the computing industry matured, I actually find that I can buy a vendor’s system as cheaply – and in some cases far more cheaply – than I can build it myself.   This paradigm holds true for almost any product, even clothing and furniture. And it’s also held true for software… Mostly. If you need an office productivity package, you simply buy one or use open-sourced software for that. There’s really no need to write your own Word Processor – it’s kind of been done a thousand times over. Even if you need a full system for customer relationship management or other needs, you simply buy one. But there is no “cloud solution in a box”.  Sure, if you’re after “Software as a Service” – type solutions, like being able to process video (Windows Azure Media Services) or running a Pig or Hive job in Hadoop (Hadoop on Windows Azure) you can simply use one of those, or if you just want to deploy a Virtual Machine (Windows Azure Virtual Machines) you can get that, but if you’re looking for a solution to a problem your organization has, you may need to mix Software, Infrastructure, and perhaps even Platforms (such as Windows Azure Computing) to solve the issue. It’s all about starting from the problem-end first. We’ve become so accustomed to looking for a box of software that will solve the problem, that we often start with the solution and try to fit it to the problem, rather than the other way around.  When I talk with my fellow architects at other companies, one of the hardest things to get them to do is to ignore the technology for a moment and describe what the issues are. It’s interesting to monitor the conversation and watch how many times we deviate from the problem into the solution. So, in your work today, try a little experiment: watch how many times you go after a problem by starting with the solution. Tomorrow, make a conscious effort to reverse that. You might be surprised at the results.

  • Windows Cloud Services Aren’t Exclusive to Microsoft

    - by Ken Cox [MVP]
    The Windows Azure brand has captured mindshare for the buzzword-du-jour, ‘cloud computing’. However, Microsoft certainly isn’t the only option for cranking up virtual machines to meet unexpected or peak demands. For example, I see that OrcsWeb has released its Windows Cloud Servers product , starting at $99.99 a month*.  Competition is a good thing - and make sure you do some cost comparisons when researching cloud resources. Some of us were unpleasantly surprised by Azure’s pricing structure...(read more)

  • Let&rsquo;s keep informed with &ldquo;Data Explorer&rdquo;

    - by Luca Zavarella
    At Pass Summit 2011 a new project was announced. It’s a Microsoft SQL Azure Lab and its codename is Microsoft “Data Explorer”. According to the official blog (http://blogs.msdn.com/b/dataexplorer/), this new tool provides an innovative way to acquire new knowledge from the data that interest you. In a nutshell, Data Explorer allows you to combine data from multiple sources, to publish and share the result. In addition, you can generate data streams in the RESTful open format (Open Data Protocol), and they can then be used by other applications. Nonetheless we can still use Excel or PowerPivot to analyze the results. Sources can be varied: Excel spreadsheets, text files, databases, Windows Azure Marketplace, etc.. For those who are not familiar with this resource, I strongly suggest you to keep an eye on the data services available to the Marketplace: https://datamarket.azure.com/browse/Data To tell the truth, as I read the above blog post, I was tempted to think of the Data Explorer as a "SSIS on Azure" addressed to the Power User. In fact, reading the response from Tim Mallalieu (Group Program Manager of Data Explorer) to the comment made to his post, I had a positive response to my first impression: “…we originally thinking of ourselves as Self-Service ETL. As we talked to more folks and started partnering with other teams we realized that would be an area that we can add value but that there were more opportunities emerging.” The typical operations of the ETL phase ( processing and organization of data in different formats) can be obtained thanks to Data Explorer Mashup. This is an image of the tool: The flexibility in the manipulation of information is given by Data Explorer Formula Language. This is a formula-based Excel-style specific language: Anyone wishing to know more can check the project page in addition to aforementioned blog: http://www.microsoft.com/en-us/sqlazurelabs/labs/dataexplorer.aspx In light of this new project, there is no doubt about the intention of Microsoft to get closer and closer to the Power User, providing him flexible and very easy to use tools for data analysis. The prime example of this is PowerPivot. The question that remains is always the same: having in a company more Power User will implicitly mean having different data models representing the same reality. But this would inevitably lead to anarchical data management... What do you think about that?

  • Is it possible to boot already installed version of Ubuntu from within Win7, e.g. with a vm?

    - by Fizzik
    I have both Ubuntu 12.10 and Win7 installed. I use the former mostly for scientific simulations and the latter for applications. The problem I came across with this configuration is that the simulations take quite a while, and I'm not satisfied enough with solutions like Wine to run the Windows apps while the simulation runs. I would rather not install the simulation programs again, since it took quite an effort. So, is it possible to boot the already installed version of Ubuntu from within Windows 7 via VirtualBox or or something else?

  • Ruby on Rails: url_for :back leads to NoMethodError for back_url

    - by Platinum Azure
    Hi all, I'm trying to use url_for(:back) to create a redirect leading back to a previous page upon a user's logging in. I've had it working successfully for when the user just goes to the login page on his or her own. However, when the user is redirected to the login page due to accessing a page requiring that the user be authenticated, the redirect sends the user back to the page before the one s/he had tried to access with insufficient permissions. I'm trying to modify my login controller action to deal with the redirect properly. My plan is to have a query string parameter "redirect" that is used when a forced redirect occurs. In the controller, if that parameter exists that URL is used; otherwise, url_for(:back) is used, or if that doesn't work (due to lack of HTTP_REFERER), then the user is redirected to the site's home page. Here is the code snippet which is supposed to implement this logic: if params[:redirect] @url = params[:redirect] else @url = url_for :back @url ||= url_for :controller => "home", :action => "index" end The error I get is: NoMethodError in UsersController#login undefined method `back_url' for # RAILS_ROOT: [obscured] Application Trace | Framework Trace | Full Trace

  • Ruby libraries for parsing .doc files?

    - by Platinum Azure
    Hi all, I was just wondering if anyone knew of any good libraries for parsing .doc files (and similar formats, like .odt) to extract text, yet also keep formatting information where possible for display on a website. Capability of doing similarly for PDFs would be a bonus, but I'm not looking as much for that. This is for a Rails project, if that helps at all. Thanks in advance!

  • How to create a "shutdown user" or "shutdown account"

    - by pcapademic
    Red Hat had a feature useful to me at the present time. There was an account, generally called "shutdown", and when you logged in with the account, the system shut down. In my specific case, I have Ubuntu Server running in a VM on my local system. The VM is running a web app, and when I'm done doing work, I want to shut down the VM. Unfortunately, I can't install VMware tools to get the "power button" based shutdown. Currently I login then sudo shutdown -h now, then type my password again, and things shutdown. Really, it's getting annoying all that waiting around and typing things. How do I replicate the "shutdown account" functionality in Ubuntu? A related question, were there any security gotchas that motivated people to stop using this kind of account?

  • Script to set NO_HEARTBEAT Flag

    - by Koppar
    The new plugin provides some flags to help debug the browser side VM. Below are the flags: JPI_PLUGIN2_DEBUG=1JPI_PLUGIN2_VERBOSE=1 The above 2 provide tracing information JPI_PLUGIN2_NO_HEARTBEAT = 1 This disables sending of  heartbeat messages between browser side VM and the client JVM instance(s). This lets the client JVM stay independent of browser side VM. These are to be set as system environment variables. Many a times we are required to set them using scripts. Here is a small script to achieve the same: -----------set_jpi_flags.vbs------------------------------------------ Set WSHShell = WScript.CreateObject("WScript.Shell")Set WshEnv = WshShell.Environment("USER")WshEnv("JPI_PLUGIN2_NO_HEARTBEAT") = "1"WshEnv("JPI_PLUGIN2_DEBUG") = "1"WshEnv("JPI_PLUGIN2_VERBOSE") = "1"WScript.Echo WshEnv("JPI_PLUGIN2_NO_HEARTBEAT")   ---- displays the value of the NO_HEARTBEAT var ---------------------------------------------------------------------------

  • JDK bug migration: components and subcomponents

    - by darcy
    One subtask of the JDK migration from the legacy bug tracking system to JIRA was reclassifying bugs from a three-level taxonomy in the legacy system, (product, category, subcategory), to a fundamentally two-level scheme in our customized JIRA instance, (component, subcomponent). In the JDK JIRA system, there is technically a third project-level classification, but by design a large majority of JDK-related bugs were migrated into a single "JDK" project. In the end, over 450 legacy subcategories were simplified into about 120 subcomponents in JIRA. The 120 subcomponents are distributed among 17 components. A rule of thumb used was that a subcategory had to have at least 50 bugs in it for it to be retained. Below is a listing the component / subcomponent classification of the JDK JIRA project along with some notes and guidance on which OpenJDK email addresses cover different areas. Eventually, a separate incidents project to host new issues filed at bugs.sun.com will use a slightly simplified version of this scheme. The preponderance of bugs and subcomponents for the JDK are in library-related areas, with components named foo-libs and subcomponents primarily named after packages. While there was an overall condensation of subcomponents in the migration, in some cases long-standing informal divisions in core libraries based on naming conventions in the description were promoted to formal subcomponents. For example, hundreds of bugs in the java.util subcomponent whose descriptions started with "(coll)" were moved into java.util:collections. Likewise, java.lang bugs starting with "(reflect)" and "(proxy)" were moved into java.lang:reflect. client-libs (Predominantly discussed on 2d-dev and awt-dev and swing-dev.) 2d demo java.awt java.awt:i18n java.beans (See beans-dev.) javax.accessibility javax.imageio javax.sound (See sound-dev.) javax.swing core-libs (See core-libs-dev.) java.io java.io:serialization java.lang java.lang.invoke java.lang:class_loading java.lang:reflect java.math java.net java.nio (Discussed on nio-dev.) java.nio.charsets java.rmi java.sql java.sql:bridge java.text java.util java.util.concurrent java.util.jar java.util.logging java.util.regex java.util:collections java.util:i18n javax.annotation.processing javax.lang.model javax.naming (JNDI) javax.script javax.script:javascript javax.sql org.openjdk.jigsaw (See jigsaw-dev.) security-libs (See security-dev.) java.security javax.crypto (JCE: includes SunJCE/MSCAPI/UCRYPTO/ECC) javax.crypto:pkcs11 (JCE: PKCS11 only) javax.net.ssl (JSSE, includes javax.security.cert) javax.security javax.smartcardio javax.xml.crypto org.ietf.jgss org.ietf.jgss:krb5 other-libs corba corba:idl corba:orb corba:rmi-iiop javadb other (When no other subcomponent is more appropriate; use judiciously.) Most of the subcomponents in the xml component are related to jaxp. xml jax-ws jaxb javax.xml.parsers (JAXP) javax.xml.stream (JAXP) javax.xml.transform (JAXP) javax.xml.validation (JAXP) javax.xml.xpath (JAXP) jaxp (JAXP) org.w3c.dom (JAXP) org.xml.sax (JAXP) For OpenJDK, most JVM-related bugs are connected to the HotSpot Java virtual machine. hotspot (See hotspot-dev.) build compiler (See hotspot-compiler-dev.) gc (garbage collection, see hotspot-gc-dev.) jfr (Java Flight Recorder) jni (Java Native Interface) jvmti (JVM Tool Interface) mvm (Multi-Tasking Virtual Machine) runtime (See hotspot-runtime-dev.) svc (Servicability) test core-svc (See serviceability-dev.) debugger java.lang.instrument java.lang.management javax.management tools The full JDK bug database contains entries related to legacy virtual machines that predate HotSpot as well as retired APIs. vm-legacy jit (Sun Exact VM) jit_symantec (Symantec VM, before Exact VM) jvmdi (JVM Debug Interface ) jvmpi (JVM Profiler Interface ) runtime (Exact VM Runtime) Notable command line tools in the $JDK/bin directory have corresponding subcomponents. tools appletviewer apt (See compiler-dev.) hprof jar javac (See compiler-dev.) javadoc(tool) (See compiler-dev.) javah (See compiler-dev.) javap (See compiler-dev.) jconsole launcher updaters (Timezone updaters, etc.) visualvm Some aspects of JDK infrastructure directly affect JDK Hg repositories, but other do not. infrastructure build (See build-dev and build-infra-dev.) licensing (Covers updates to the third party readme, licenses, and similar files.) release_eng (Release engineering) staging (Staging of web pages related to JDK releases.) The specification subcomponent encompasses the formal language and virtual machine specifications. specification language (The Java Language Specification) vm (The Java Virtual Machine Specification) The code for the deploy and install areas is not currently included in OpenJDK. deploy deployment_toolkit plugin webstart install auto_update install servicetags In the JDK, there are a number of cross-cutting concerns whose organization is essentially orthogonal to other areas. Since these areas generally have dedicated teams working on them, it is easier to find bugs of interest if these bugs are grouped first by their cross-cutting component rather than by the affected technology. docs doclet guides hotspot release_notes tools tutorial embedded build hotspot libraries globalization locale-data translation performance hotspot libraries The list of subcomponents will no doubt grow over time, but my inclination is to resist that growth since the addition of each subcomponent makes the system as a whole more complicated and harder to use. When the system gets closer to being externalized, I plan to post more blog entries describing recommended use of various custom fields in the JDK project.
