• How do I get a remote tracking branch to stay up to date with remote origin in a bare Git repository?

  - by Beau Simensen

  I am trying to maintain a bare copy of a Git repository and having some issues keeping the remote tracking branches up to date. I create the remote tracking branches like this: git branch -t 0.1 origin/0.1 This seems to do what I need to do for that point in time. However, if I make changes to origin and then fetch with the bare repo, things start to fall apart. My workflow looks like this: git fetch origin It looks like all of the commits come in at that point, but my local copy of 0.1 is not being updated. I can see that the changes have been brought into the repository by doing the following: git diff 0.1 refs/remotes/origin/0.1 What do I need to do to get my tracking branch updated with the remote's updates? I feel like I must be missing a step or a flag somewhere.

• Where is the best place to call the .tolist(); inside my controller classes or inside my model repository classes

  - by john G

  I have the following action method, inside my asp.net mvc web application:- public JsonResult LoadZoneByDataCenter(string id) { var zonelist = repository.getrealtedzone(Convert.ToInt32(id)).ToList(); //code goes here Which calls the following model repository method:- public IQueryable<Zone> getrealtedzone(int? dcid) { return tms.Zones.Where(a=> a.DataCenterID == dcid || dcid == null); } Currently I am calling the .tolist() which will interpret the Database from my action method, but my question is where is the best place to call the .tolist() inside the controller or inside the model classes and why ? thanks

• Is there an open source repository for SQL code?

  - by morpheous

  I find myself writing SQL code (queries or stored procs) to solve problems that can definitely be defined as 'patterns' that occur frequently in business. Rather than having to wrack my brain each time I encounter a new problem (which must have been solved a countless times by other coders/db analysts, I wondered if there was a repository I could go to check out (peer reviewed) code - and maybe add my two pence every now and then. I know different db vendors tend to write slightly variant forms of SQL - but there could still be a repository with ANSI stuff and proprietary stuff. Hopefully, such a site would encourage more people to write standardized SQL. Is there such a site?. If no - why not? (would anyone else be interested in such a site?) If such a site exists, please provide link(s), as Google is not finding anything remotely useful.

• How to create a repository workspace which contains all of the components of a stream using scm tool?

  - by user470184

  I'm attempting to automate the updating of a file in a stream using 'scm' Here is how I think it should work : Login to the repository as current user (me) Create a new repository workspace which contains all of the components of a given Stream Load the components of the newly created workspace Update the file I'm on point 2. Reading about the 'create workspace' doc on http://pic.dhe.ibm.com/infocenter/rtc/v1r0m0/index.jsp?topic=%2Fcom.ibm.team.scm.doc%2Ftopics%2Fc_scm_cli.html it does'nt mention how to create a new workspace which contains all of the components of a given stream. So how can I implement point 2 ? Any comments on my methodolgy if can be improved upon also appreciated.

• Svn: how to remove all deleted files from repository ?

  - by Patrick

  I have a script in which I add all new files before to commit my working copy to my repository with this line: svn status | grep ^\? | awk '{print $2}' | xargs svn add I now want to add a line that delete from repository all deleted files in my working copy. In other terms, I cannot specify them one by one, and I need to detect them with svn status and then automatically remove them. However the line doesn't work. svn status | grep ^\! | awk '{print $2}' | xargs svn --force delete As you can see I've replaced "?" with "!" and "add" with "--force delete" Could you tell me why it doesn't work ? ps. I know it is a risky procedure. I've already discussed all about it. thanks thanks

• How to give friend access to git repository without giving command line access?

  - by Jack Humphries

  I have some git repositories running on my server and I would like to give a friend read/write access to one. That's simple: I add him as a user, give him SSH access, and change the permissions to the repository folder. Everything works fine; I'm able to clone the git repository using Xcode and change things (ssh://www.example.com/repo.git). However, I do not want him to have command line access. If I recall correctly, Github does not give command line access to those who SSH in. I'm using Snow Leopard Server. Is this more of a server issue or a git issue? Do you have any idea where to begin? Setting the user's Login Shell to none (as opposed to /bin/bash) cuts off access to everything.

• How Can I Point My Local Testing Server at My GitHub Repository?

  - by Goober

  Up until a few days ago, I had a particular setup that was as follows. Using SVN, all of the websites that I developed were committed to a source control drop box on a local testing server. Then using IIS, a new website was set up to point at the last revision of each particular website I developed and display it to the outside world using a specific URL. I have just moved over to using git and github, meaning all of my source controlled code is now no longer stored on a local testing server. As a result of this, I am not sure how I can go about doing a similar thing to what I did with the SVN setup, however I need to be able to essentially have that same setup again, just using Git. So basically, how can I go about getting my local testing server to point at the GitHub repository for that site? Help greatly appreciated.

• Subversion for web designer: repository on a network share and ftp to the live server?

  - by ceatus

  My configuration: htdocs on a windows network share (z:) web developers check out with dreamweaver modify and check in back to the drive z LAMP running on a Ubuntu server virtualized on Hyper-V with apache that point on the z drive for dev in order to test the websites Upload by FTP on the live server Now: I need multiple access to the repository, keep them on a network shares and we manage about 200 websites. All the web developers, administrators and IT need to access to the share. I found out that creating a svn server is the best way for me, so I created it on a Ubuntu Server which is virtualized on Hyper-V. Right now I have the repos local on the Ubuntu Server but I'd like them on my network drive and I'd like to have a post-commit, if possible, in order to ftp directly on my live server. Do you guys think that a WebDav solution would be better? Thanks in advance Angelo

• What is the correct root file to import to aptana from an xampp folder/existing web app or git repository?

  - by gaff

  Very noob question - all of this is new to me - not really sure how to get started. Overview: I'm taking over an existing wep project that has been developed in aptana and deployed in xampp setup - I also have access to Git repository on local directory. I want to import the web application into aptana, run it and begin updating/editing - bit of steep learning curve for me What is the best way to import? And what should I import? What should it look like in aptanan? I tried importing what I think is the root file from the git folder ("existing folder as new project")- it contains things like css, doc, img and js. This looks right to me - but might not be. Thanks, Gaff

• Setting up an SVN repository on a windows server to work with XCode.

  - by Tejaswi Yerukalapudi

  Hi, I need to setup an SVN repository for an iPhone / iPad app that I'm working on. It needs to be setup on a Windows server 2003 instance. We run VSS on it, but it doesn't really work all that well with XCode, so I'd like to migrate ASAP. The problem is, I'm a new graduate and this is the first time I'll be using a souce control software, so any tutorials on how to set one up, configure it to work correctly with Macs using XCode are greatly appreciated! Though it's not a priority, I'd also like to try to get my company to ditch VSS for SVN (Been reading this article yesterday - http://www.codinghorror.com/blog/2006/08/source-control-anything-but-sourcesafe.html). How hard is it to migrate existing builds in VSS into something like SVN? Thanks, Teja

• Add entire 300 GB filesystem to Git Annex repository?

  - by Ryan Lester

  By default, I get an error that I have too many open files from the process. If I lift the limit manually, I get an error that I'm out of memory. For whatever reason, it seems that Git Annex in its current state is not optimised for this sort of task (adding thousands of files to a repository at once). As a possible solution, my next thought was to do something like: cd / find . -type d | git annex add --$NONRECURSIVELY find . -type f | git annex add # Need to add parent directories of each file first or adding files fails The problem with this solution is that there doesn't seem from the documentation to be a way to non-recursively add a directory in Git Annex. Is there something I'm missing or a workaround for this? If my proposed solution is a dead end, are there other ways that people have solved this problem?

• Upgrade Subversion 1.6 to 1.7 on CentOS? (can't find yum repository)

  - by user743919

  I want to upgrade my SVN Server from 1.6 to 1.7. Unfortunately I can't find anything on the internet how to do this with yum. I have checked rpmforge-extras but it has only svn 1.6 and not 1.7 I wanted to update with yum because this is the most secure way for me. I'm not an experienced Linux user. Is there a yum repository that contains 1.7 (subversion.x86_64 0:1.7.xxxxx.el5.rfx) I hope somebody can help me out? If there is non, perhaps a short explenation how to update with just step by step.

• Windows 7 Phone Database – Querying with Views and Filters

  - by SeanMcAlinden

  I’ve just added a feature to Rapid Repository to greatly improve how the Windows 7 Phone Database is queried for performance (This is in the trunk not in Release V1.0). The main concept behind it is to create a View Model class which would have only the minimum data you need for a page. This View Model is then stored and retrieved rather than the whole list of entities. Another feature of the views is that they can be pre-filtered to even further improve performance when querying. You can download the source from the Microsoft Codeplex site http://rapidrepository.codeplex.com/. Setting up a view Lets say you have an entity that stores lots of data about a game result for example: GameScore entity public class GameScore : IRapidEntity {     public Guid Id { get; set; }     public string GamerId {get;set;}     public string Name { get; set; }     public Double Score { get; set; }     public Byte[] ThumbnailAvatar { get; set; }     public DateTime DateAdded { get; set; } }   On your page you want to display a list of scores but you only want to display the score and the date added, you create a View Model for displaying just those properties. GameScoreView public class GameScoreView : IRapidView {     public Guid Id { get; set; }     public Double Score { get; set; }     public DateTime DateAdded { get; set; } }   Now you have the view model, the first thing to do is set up the view at application start up. This is done using the following syntax. View Setup public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score }); } As you can see, using a little bit of lambda syntax, you put in the code for constructing a single view, this is used internally for mapping an entity to a view. *Note* you do not need to map the Id property, this is done automatically, a view model id will always be the same as it’s corresponding entity.   Adding Filters One of the cool features of the view is that you can add filters to limit the amount of data stored in the view, this will dramatically improve performance. You can add multiple filters using the fluent syntax if required. In this example, lets say that you will only ever show the scores for the last 10 days, you could add a filter like the following: Add single filter public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score })         .AddFilter(x => x.DateAdded > DateTime.Now.AddDays(-10)); } If you wanted to further limit the data, you could also say only scores above 100: Add multiple filters public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score })         .AddFilter(x => x.DateAdded > DateTime.Now.AddDays(-10))         .AddFilter(x => x.Score > 100); }   Querying the view model So the important part is how to query the data. This is done using the repository, there is a method called Query which accepts the type of view as a generic parameter (you can have multiple View Model types per entity type) You can either use the result of the query method directly or perform further querying on the result is required. Querying the View public void DisplayScores() {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     List<GameScoreView> scores = repository.Query<GameScoreView>();       // display logic } Further Filtering public void TodaysScores() {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     List<GameScoreView> todaysScores = repository.Query<GameScoreView>().Where(x => x.DateAdded > DateTime.Now.AddDays(-1)).ToList();       // display logic }   Retrieving the actual entity Retrieving the actual entity can be done easily by using the GetById method on the repository. Say for example you allow the user to click on a specific score to get further information, you can use the Id populated in the returned View Model GameScoreView and use it directly on the repository to retrieve the full entity. Get Full Entity public void GetFullEntity(Guid gameScoreViewId) {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     GameScore fullEntity = repository.GetById(gameScoreViewId);       // display logic } Synchronising The View If you are upgrading from Rapid Repository V1.0 and are likely to have data in the repository already, you will need to perform a synchronisation to ensure the views and entities are fully in sync. You can either do this as a one off during the application upgrade or if you are a little more cautious, you could run this at each application start up. Synchronise the view public void MyUpgradeTasks() {     RapidRepository<GameScore>.SynchroniseView<GameScoreView>(); } It’s worth noting that in normal operation, the view keeps itself in sync with the entities so this is only really required if you are upgrading from V1.0 to V2.0 when it gets released shortly.   Summary I really hope you like this feature, it will be great for performance and I believe supports good practice by promoting the use of View Models for specific pages. I’m hoping to produce a beta for this over the next few days, I just want to add some more tests and hopefully iron out any bugs. I would really appreciate any thoughts on this feature and would really love to know of any bugs you find. You can download the source from the following : http://rapidrepository.codeplex.com/ Kind Regards, Sean McAlinden.

• Setting up a local AI server - easy with Solaris 11

  - by Stefan Hinker

  Many things are new in Solaris 11, Autoinstall is one of them.  If, like me, you've known Jumpstart for the last 2 centuries or so, you'll have to start from scratch.  Well, almost, as the concepts are similar, and it's not all that difficult.  Just new. I wanted to have an AI server that I could use for demo purposes, on the train if need be.  That answers the question of hardware requirements: portable.  But let's start at the beginning. First, you need an OS image, of course.  In the new world of Solaris 11, it is now called a repository.  The original can be downloaded from the Solaris 11 page at Oracle.   What you want is the "Oracle Solaris 11 11/11 Repository Image", which comes in two parts that can be combined using cat.  MD5 checksums for these (and all other downloads from that page) are available closer to the top of the page. With that, building the repository is quick and simple: # zfs create -o mountpoint=/export/repo rpool/ai/repo # zfs create rpool/ai/repo/s11 # mount -o ro -F hsfs /tmp/sol-11-1111-repo-full.iso /mnt # rsync -aP /mnt/repo /export/repo/s11 # umount /mnt # pkgrepo rebuild -s /export/repo/sol11/repo # zfs snapshot rpool/ai/repo/sol11@fcs # pkgrepo info -s /export/repo/sol11/repo PUBLISHER PACKAGES STATUS UPDATED solaris 4292 online 2012-03-12T20:47:15.378639Z That's all there's to it.  Let's make a snapshot, just to be on the safe side.  You never know when one will come in handy.  To use this repository, you could just add it as a file-based publisher: # pkg set-publisher -g file:///export/repo/sol11/repo solaris In case I'd want to access this repository through a (virtual) network, i'll now quickly activate the repository-service: # svccfg -s application/pkg/server \ setprop pkg/inst_root=/export/repo/sol11/repo # svccfg -s application/pkg/server setprop pkg/readonly=true # svcadm refresh application/pkg/server # svcadm enable application/pkg/server That's all you need - now point your browser to http://localhost/ to view your beautiful repository-server. Step 1 is done.  All of this, by the way, is nicely documented in the README file that's contained in the repository image. Of course, we already have updates to the original release.  You can find them in MOS in the Oracle Solaris 11 Support Repository Updates (SRU) Index.  You can simply add these to your existing repository or create separate repositories for each SRU.  The individual SRUs are self-sufficient and incremental - SRU4 includes all updates from SRU2 and SRU3.  With ZFS, you can also get both: A full repository with all updates and at the same time incremental ones up to each of the updates: # mount -o ro -F hsfs /tmp/sol-11-1111-sru4-05-incr-repo.iso /mnt # pkgrecv -s /mnt/repo -d /export/repo/sol11/repo '*' # umount /mnt # pkgrepo rebuild -s /export/repo/sol11/repo # zfs snapshot rpool/ai/repo/sol11@sru4 # zfs set snapdir=visible rpool/ai/repo/sol11 # svcadm restart svc:/application/pkg/server:default The normal repository is now updated to SRU4.  Thanks to the ZFS snapshots, there is also a valid repository of Solaris 11 11/11 without the update located at /export/repo/sol11/.zfs/snapshot/fcs . If you like, you can also create another repository service for each update, running on a separate port. But now lets continue with the AI server.  Just a little bit of reading in the dokumentation makes it clear that we will need to run a DHCP server for this.  Since I already have one active (for my SunRay installation) and since it's a good idea to have these kinds of services separate anyway, I decided to create this in a Zone.  So, let's create one first: # zfs create -o mountpoint=/export/install rpool/ai/install # zfs create -o mountpoint=/zones rpool/zones # zonecfg -z ai-server zonecfg:ai-server> create create: Using system default template 'SYSdefault' zonecfg:ai-server> set zonepath=/zones/ai-server zonecfg:ai-server> add dataset zonecfg:ai-server:dataset> set name=rpool/ai/install zonecfg:ai-server:dataset> set alias=install zonecfg:ai-server:dataset> end zonecfg:ai-server> commit zonecfg:ai-server> exit # zoneadm -z ai-server install # zoneadm -z ai-server boot ; zlogin -C ai-server Give it a hostname and IP address at first boot, and there's the Zone.  For a publisher for Solaris packages, it will be bound to the "System Publisher" from the Global Zone.  The /export/install filesystem, of course, is intended to be used by the AI server.  Let's configure it now: #zlogin ai-server root@ai-server:~# pkg install install/installadm root@ai-server:~# installadm create-service -n x86-fcs -a i386 \ -s pkg://solaris/install-image/[email protected],5.11-0.175.0.0.0.2.1482 \ -d /export/install/fcs -i 192.168.2.20 -c 3 With that, the core AI server is already done.  What happened here?  First, I installed the AI server software.  IPS makes that nice and easy.  If necessary, it'll also pull in the required DHCP-Server and anything else that might be missing.  Watch out for that DHCP server software.  In Solaris 11, there are two different versions.  There's the one you might know from Solaris 10 and earlier, and then there's a new one from ISC.  The latter is the one we need for AI.  The SMF service names of both are very similar.  The "old" one is "svc:/network/dhcp-server:default". The ISC-server comes with several SMF-services. We at least need "svc:/network/dhcp/server:ipv4".  The command "installadm create-service" creates the installation-service. It's called "x86-fcs", serves the "i386" architecture and gets its boot image from the repository of the system publisher, using version 5.11,5.11-0.175.0.0.0.2.1482, which is Solaris 11 11/11.  (The option "-a i386" in this example is optional, since the installserver itself runs on a x86 machine.) The boot-environment for clients is created in /export/install/fcs and the DHCP-server is configured for 3 IP-addresses starting at 192.168.2.20.  This configuration is stored in a very human readable form in /etc/inet/dhcpd4.conf.  An AI-service for SPARC systems could be created in the very same way, using "-a sparc" as the architecture option. Now we would be ready to register and install the first client.  It would be installed with the default "solaris-large-server" using the publisher "http://pkg.oracle.com/solaris/release" and would query it's configuration interactively at first boot.  This makes it very clear that an AI-server is really only a boot-server.  The true source of packets to install can be different.  Since I don't like these defaults for my demo setup, I did some extra config work for my clients. The configuration of a client is controlled by manifests and profiles.  The manifest controls which packets are installed and how the filesystems are layed out.  In that, it's very much like the old "rules.ok" file in Jumpstart.  Profiles contain additional configuration like root passwords, primary user account, IP addresses, keyboard layout etc.  Hence, profiles are very similar to the old sysid.cfg file. The easiest way to get your hands on a manifest is to ask the AI server we just created to give us it's default one.  Then modify that to our liking and give it back to the installserver to use: root@ai-server:~# mkdir -p /export/install/configs/manifests root@ai-server:~# cd /export/install/configs/manifests root@ai-server:~# installadm export -n x86-fcs -m orig_default \ -o orig_default.xml root@ai-server:~# cp orig_default.xml s11-fcs.small.local.xml root@ai-server:~# vi s11-fcs.small.local.xml root@ai-server:~# more s11-fcs.small.local.xml <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance name="S11 Small fcs local"> <target> <logical> <zpool name="rpool" is_root="true"> <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"/> </zpool> </logical> </target> <software type="IPS"> <destination> <image> <!-- Specify locales to install --> <facet set="false">facet.locale.*</facet> <facet set="true">facet.locale.de</facet> <facet set="true">facet.locale.de_DE</facet> <facet set="true">facet.locale.en</facet> <facet set="true">facet.locale.en_US</facet> </image> </destination> <source> <publisher name="solaris"> <origin name="http://192.168.2.12/"/> </publisher> </source> <!-- By default the latest build available, in the specified IPS repository, is installed. If another build is required, the build number has to be appended to the 'entire' package in the following form: <name>pkg:/[email protected]#</name> --> <software_data action="install"> <name>pkg:/[email protected],5.11-0.175.0.0.0.2.0</name> <name>pkg:/group/system/solaris-small-server</name> </software_data> </software> </ai_instance> </auto_install> root@ai-server:~# installadm create-manifest -n x86-fcs -d \ -f ./s11-fcs.small.local.xml root@ai-server:~# installadm list -m -n x86-fcs Manifest Status Criteria -------- ------ -------- S11 Small fcs local Default None orig_default Inactive None The major points in this new manifest are: Install "solaris-small-server" Install a few locales less than the default.  I'm not that fluid in French or Japanese... Use my own package service as publisher, running on IP address 192.168.2.12 Install the initial release of Solaris 11:  pkg:/[email protected],5.11-0.175.0.0.0.2.0 Using a similar approach, I'll create a default profile interactively and use it as a template for a few customized building blocks, each defining a part of the overall system configuration.  The modular approach makes it easy to configure numerous clients later on: root@ai-server:~# mkdir -p /export/install/configs/profiles root@ai-server:~# cd /export/install/configs/profiles root@ai-server:~# sysconfig create-profile -o

192.168.2.100 user.xml None Here's the idea behind these files: "general.xml" contains settings valid for all my clients.  Stuff like DNS servers, for example, which in my case will always be the same. "user.xml" only contains user definitions.  That is, a root password and a primary user.Both of these profiles will be valid for all clients (for now). "mars.xml" defines network settings for an individual client.  This profile is associated with an IP-Address.  For this to work, I'll have to tweak the DHCP-settings in the next step: root@ai-server:~# installadm create-client -e 08:00:27:AA:3D:B1 -n x86-fcs root@ai-server:~# vi /etc/inet/dhcpd4.conf root@ai-server:~# tail -5 /etc/inet/dhcpd4.conf host 080027AA3DB1 { hardware ethernet 08:00:27:AA:3D:B1; fixed-address 192.168.2.100; filename "01080027AA3DB1"; } This completes the client preparations.  I manually added the IP-Address for mars to /etc/inet/dhcpd4.conf.  This is needed for the "mars.xml" profile.  Disabling arbitrary DHCP-replies will shut up this DHCP server, making my life in a shared environment a lot more peaceful ;-)Now, I of course want this installation to be completely hands-off.  For this to work, I'll need to modify the grub boot menu for this client slightly.  You can find it in /etc/netboot.  "installadm create-client" will create a new boot menu for every client, identified by the client's MAC address.  The template for this can be found in a subdirectory with the name of the install service, /etc/netboot/x86-fcs in our case.  If you don't want to change this manually for every client, modify that template to your liking instead. root@ai-server:~# cd /etc/netboot root@ai-server:~# cp menu.lst.01080027AA3DB1 menu.lst.01080027AA3DB1.org root@ai-server:~# vi menu.lst.01080027AA3DB1 root@ai-server:~# diff menu.lst.01080027AA3DB1 menu.lst.01080027AA3DB1.org 1,2c1,2 < default=1 < timeout=10 --- > default=0 > timeout=30 root@ai-server:~# more menu.lst.01080027AA3DB1 default=1 timeout=10 min_mem64=0 title Oracle Solaris 11 11/11 Text Installer and command line kernel$ /x86-fcs/platform/i86pc/kernel/$ISADIR/unix -B install_media=htt p://$serverIP:5555//export/install/fcs,install_service=x86-fcs,install_svc_addre ss=$serverIP:5555 module$ /x86-fcs/platform/i86pc/$ISADIR/boot_archive title Oracle Solaris 11 11/11 Automated Install kernel$ /x86-fcs/platform/i86pc/kernel/$ISADIR/unix -B install=true,inst all_media=http://$serverIP:5555//export/install/fcs,install_service=x86-fcs,inst all_svc_address=$serverIP:5555,livemode=text module$ /x86-fcs/platform/i86pc/$ISADIR/boot_archive Now just boot the client off the network using PXE-boot.  For my demo purposes, that's a client from VirtualBox, of course.  That's all there's to it.  And despite the fact that this blog entry is a little longer - that wasn't that hard now, was it?

• SPARC T3-1 Record Results Running JD Edwards EnterpriseOne Day in the Life Benchmark with Added Batch Component

  - by Brian

  Using Oracle's SPARC T3-1 server for the application tier and Oracle's SPARC Enterprise M3000 server for the database tier, a world record result was produced running the Oracle's JD Edwards EnterpriseOne applications Day in the Life benchmark run concurrently with a batch workload. The SPARC T3-1 server based result has 25% better performance than the IBM Power 750 POWER7 server even though the IBM result did not include running a batch component. The SPARC T3-1 server based result has 25% better space/performance than the IBM Power 750 POWER7 server as measured by the online component. The SPARC T3-1 server based result is 5x faster than the x86-based IBM x3650 M2 server system when executing the online component of the JD Edwards EnterpriseOne 9.0.1 Day in the Life benchmark. The IBM result did not include a batch component. The SPARC T3-1 server based result has 2.5x better space/performance than the x86-based IBM x3650 M2 server as measured by the online component. The combination of SPARC T3-1 and SPARC Enterprise M3000 servers delivered a Day in the Life benchmark result of 5000 online users with 0.875 seconds of average transaction response time running concurrently with 19 Universal Batch Engine (UBE) processes at 10 UBEs/minute. The solution exercises various JD Edwards EnterpriseOne applications while running Oracle WebLogic Server 11g Release 1 and Oracle Web Tier Utilities 11g HTTP server in Oracle Solaris Containers, together with the Oracle Database 11g Release 2. The SPARC T3-1 server showed that it could handle the additional workload of batch processing while maintaining the same number of online users for the JD Edwards EnterpriseOne Day in the Life benchmark. This was accomplished with minimal loss in response time. JD Edwards EnterpriseOne 9.0.1 takes advantage of the large number of compute threads available in the SPARC T3-1 server at the application tier and achieves excellent response times. The SPARC T3-1 server consolidates the application/web tier of the JD Edwards EnterpriseOne 9.0.1 application using Oracle Solaris Containers. Containers provide flexibility, easier maintenance and better CPU utilization of the server leaving processing capacity for additional growth. A number of Oracle advanced technology and features were used to obtain this result: Oracle Solaris 10, Oracle Solaris Containers, Oracle Java Hotspot Server VM, Oracle WebLogic Server 11g Release 1, Oracle Web Tier Utilities 11g, Oracle Database 11g Release 2, the SPARC T3 and SPARC64 VII+ based servers. This is the first published result running both online and batch workload concurrently on the JD Enterprise Application server. No published results are available from IBM running the online component together with a batch workload. The 9.0.1 version of the benchmark saw some minor performance improvements relative to 9.0. When comparing between 9.0.1 and 9.0 results, the reader should take this into account when the difference between results is small.

Oracle offers 70 JD Edwards EnterpriseOne application modules to support a diverse set of business operations. Oracle's Day in the Life (DIL) kit is a suite of scripts that exercises most common transactions of JD Edwards EnterpriseOne applications, including business processes such as payroll, sales order, purchase order, work order, and other manufacturing processes, such as ship confirmation. These are labeled by industry acronyms such as SCM, CRM, HCM, SRM and FMS. The kit's scripts execute transactions typical of a mid-sized manufacturing company. The workload consists of online transactions and the UBE workload of 15 short and 4 long UBEs. LoadRunner runs the DIL workload, collects the user’s transactions response times and reports the key metric of Combined Weighted Average Transaction Response time. The UBE processes workload runs from the JD Enterprise Application server. Oracle's UBE processes come as three flavors: Short UBEs < 1 minute engage in Business Report and Summary Analysis, Mid UBEs > 1 minute create a large report of Account, Balance, and Full Address, Long UBEs > 2 minutes simulate Payroll, Sales Order, night only jobs. The UBE workload generates large numbers of PDF files reports and log files. The UBE Queues are categorized as the QBATCHD, a single threaded queue for large UBEs, and the QPROCESS queue for short UBEs run concurrently. One of the Oracle Solaris Containers ran 4 Long UBEs, while another Container ran 15 short UBEs concurrently. The mixed size UBEs ran concurrently from the SPARC T3-1 server with the 5000 online users driven by the LoadRunner. Oracle’s UBE process performance metric is Number of Maximum Concurrent UBE processes at transaction rate, UBEs/minute. Key Points and Best Practices Two JD Edwards EnterpriseOne Application Servers and two Oracle Fusion Middleware WebLogic Servers 11g R1 coupled with two Oracle Fusion Middleware 11g Web Tier HTTP Server instances on the SPARC T3-1 server were hosted in four separate Oracle Solaris Containers to demonstrate consolidation of multiple application and web servers.

• What ever happened to the Defense Software Reuse System (DSRS)?

  - by emddudley

  I've been reading some papers from the early 90s about a US Department of Defense software reuse initiative called the Defense Software Reuse System (DSRS). The most recent mention of it I could find was in a paper from 2000 - A Survey of Software Reuse Repositories Defense Software Repository System (DSRS) The DSRS is an automated repository for storing and retrieving Reusable Software Assets (RSAs) [14]. The DSRS software now manages inventories of reusable assets at seven software reuse support centers (SRSCs). The DSRS serves as a central collection point for quality RSAs, and facilitates software reuse by offering developers the opportunity to match their requirements with existing software products. DSRS accounts are available for Government employees and contractor personnel currently supporting Government projects... ...The DoD software community is trying to change its software engineering model from its current software cycle to a process-driven, domain-specific, architecture-based, repository-assisted way of constructing software [15]. In this changing environment, the DSRS has the highest potential to become the DoD standard reuse repository because it is the only existing deployed, operational repository with multiple interoperable locations across DoD. Seven DSRS locations support nearly 1,000 users and list nearly 9,000 reusable assets. The DISA DSRS alone lists 3,880 reusable assets and has 400 user accounts... The far-term strategy of the DSRS is to support a virtual repository. These interconnected repositories will provide the ability to locate and share reusable components across domains and among the services. An effective and evolving DSRS is a central requirement to the success of the DoD software reuse initiative. Evolving DoD repository requirements demand that DISA continue to have an operational DSRS site to support testing in an actual repository operation and to support DoD users. The classification process for the DSRS is a basic technology for providing customer support [16]. This process is the first step in making reusable assets available for implementing the functional and technical migration strategies. ... [14] DSRS - Defense Technology for Adaptable, Reliable Systems URL: http://ssed1.ims.disa.mil/srp/dsrspage.html [15] STARS - Software Technology for Adaptable, Reliable Systems URL: http://www.stars.ballston.paramax.com/index.html [16] D. E. Perry and S. S. Popovitch, “Inquire: Predicate-based use and reuse,'' in Proceedings of the 8th Knowledge-Based Software Engineering Conference, pp. 144-151, September 1993. ... Is DSRS dead, and were there any post-mortem reports on it? Are there other more-recent US government initiatives or reports on software reuse?

• Can I recover a rm -rf-ed Mercurial repository?

  - by WishCow

  I made the mistake of wiping out my entire project directory with a quick "rm -rf project". Of course, the .hg directory went with it. I had about 15-20 changesets, that I have not pushed to anyone, and I would really really like to get those back. The system is a Ubuntu machine, and the partiton where the delete happened is ext3, the project consist mostly of PHP files. I know about the guideline to not write to the disk in question. The first idea was to use the tool named scalpel, to get the PHP files back and diff them with the current version from the repo, and somehow carve the changes out. While it succeeded, it did not recover the file names (or there is a switch I'm missing), so I'm left with a few thousand sequentially named .php files, combing through them is not an option. Can a kind soul please save me, and suggest a way to: a) get the repo back, or b) get the files back, with filenames For those wondering how I did such a stupid thing: I was working on a file in Vim which I wanted to remove from the repository: :!hg rm % This complained that the file is in a subrepository, so I specified the following: :!hg rm % -R engine which complained that file has modifications, use -f to force. And this is when somehow, I made up the following command: :!rm -rf % -R engine Somehow, seeing "force" makes me do a rm -rf by reflex.
