  • How can I distribute a unique database already in production?

    - by JVerstry
    Let's assume a successful web Spring application running on a MySQL or PostgreSQL database. The traffic is becoming so high and the amount of data is becoming so big that a distributed database solution needs to be implemented to address scalability issue. Let's also assume this application is using Hibernate and the data access layer is cleanly separated with DAOs. Ideally, one should be able to add or remove databases easily. A failback solution is welcome too. What would be the best strategy to scale this database? Is it possible to minimize sharding code (Shard) in the application?

  • How to distribute a unique database already in production?

    - by JVerstry
    Let's assume a successful web spring application running on a MySql or PostGre kind of database. The traffic is becoming so high and the amount of data is becoming so big that a distributed dataase solution needs to be implemented. It is a scalability issue. Let's assume this application is using Hibernate and the data access layer is cleanly separated with DAO objects. What would be the best strategy to scale this database? Does anyone have hands on experience to share? Is it possible to minimize sharding code (Shard) in the application? Ideally, one should be able to add or remove databases easily. A failback solution is welcome too. I am not looking for you could go for sharding or you could go no sql kind of answers. I am looking for deeper answers from people with experience.

  • How safe is it to rely on thirdparty Python libs in a production product?

    - by skyler
    I'm new to Python and come from the write-everything-yourself world of PHP (at least this is how I always approached it). I'm using Flask, WTForms, Jinja2, and I've just discovered Flask-Login which I want to use. My question is about the reliability of using thirdparty libraries for core functionality in a project that is planned to be around for several years. I've installed these libraries (via pip) into a virtualenv environment. What happens if these libraries stop being distributed? Should I back up these libraries (are they eggs)? Can I store these libraries in my project itself, instead of relying on pip to install them in a virtualenv? And should I store these separately? I'm worried that I'll rely on a library for core functionality, and then one day I'll download an incompatible version through pip, or the author or maintainer will stop distributing it and it'll no longer be available. How can I protect against this, and ensure that any thirdparty libraries that I use in my projects will always be available as they are now?

  • What tools exist for designing layouts and pre-production templates for Rails 3 applications?

    - by rcd
    I develop Rails 3 applications, but prior to this, my background was a designer (typically making mockups in Photoshop and then breaking them down to HTML5/CSS3). Now, some great tools/templates exist for getting working layouts ready for Rails and other apps quickly, e.g., http://railsapps.github.com/rails-composer/. Many are using CSS Frameworks such as Twitter Bootstrap. I'd like to know whether there is a local app (for Mac) that can design layouts, much the way Dreamweaver would, but that are geared towards being utilized in a Twitter Bootstrap situation alongside Ruby (Rails) or Python apps, etc.

  • Is it possible to generate Events and Hooks in Lua for any game without built-in support?

    - by pr0tocol
    Does a game have to have built-in functions to accept and run lua scripts, or can I design Events and Hooks using Lua on any game I please, akin to the days where C code could be used to hook into the WinAPI using dlls? The reason I ask is, I am trying to create a background application that will perform events and hooks on a particular game that does not currently support lua in-game. Brief examples: Events: - An action executed by the PLAYER is detected. For instance, hitting the Q key will normally make my character use an ability, but with my Lua script running in the background, will cause a sound to play on my computer (or something). Hooks: - An action within the GAME is detected. For instance, the game spawns an enemy every minute. When an enemy spawns, the script will detect this and perform an action, for instance playing a sound locally on the computer. I would like to do both, but I know for games like Garry's Mod, the game already has built-in support for running lua scripts. Is there a way to do either events OR hooks using lua similarly to how C/C++ can connect to a game using WinAPI dlls?

  • Looking for a Silverlight 3 or 4 Menu control providing decent keyboard support.

    - by Geo
    I've an N-Tier application using Silverlight for the client. The customer as one particular request - I thought was more than reasonable: all actions – including menu navigation – has to be available through keyboard. When I tried Silverlight 4 I was surprised not to find any menu control so I downloaded several open source and commercial menu controls. I was very disappointed, after having searched for a couple of hours I didn’t manage to find any control that provide a decent keyboard support. Most controls provide no support or some basic support but not one control enabled to gain focus on the first item through the keyboard. You are able to use the keyboard (arrow keys) but you need first to select the control with the mouse! Not one control provided support for Keyboard shortcuts. Does anyone know of any Silverlight control providing descent support?

  • Is anybody using Splunk in a large-scale production environment?

    - by Nano Taboada
    I've been watching the videos at splunk.com and really it's hard to believe that one can get all those features for free, there's still that "where's the catch?" in the back of my head. So it'd be great if anybody that is actually using it Splunk on production would like to share their experiences, perhaps highlighting its benefits over, say, Nagios? Thanks much in advance.

  • Using more recent kernel for Xen Dom0 in production.

    - by thelsdj
    Does anyone have experience running Xen dom0 on a more recent kernel than the stock 2.6.18? What host distro are you running? What release of Xen (or hg/git changeset)? What set of patches are you using on kernel source? (Has anyone got the pvops dom0 stuff working in production or is it better to stick with something like the SUSE patches? Any other tips and tricks to running a more recent kernel version as dom0 would be helpful.

    We have three main servers on ec2, web, database, and search. I logged in today to find: 77 packages can be updated. 45 updates are security updates. which scares the crap out of me so I want to update these machines asap but I'm scared to just run the updates on a live running system. Is this safe to do, what's the best approach when it comes to doing security updates on production machines?

  • I want to install an MSI twice

    - by don.vince
    I have a peculiar wish to install an msi twice on a machine. The purpose of the double install is to first install under the pre-production folder, run the deployment in a safe environment prior to deploying in the production folder. We typically use separate machines to represent these different environments however in this case I need to use the same box. The two scenarios I get are as follows: I've installed pre-production, I'm happy, I want to install production, I run the msi, it asks whether I want to repair or remove the installation I've production installed, I want to install the new version of the msi, it tells me I already have a version of the product installed and I must first un-install the current version The first scenario isn't too bad as we can at that point sensibly un-install and re-install under the production folder, but the second scenario is a pain as we don't want to un-install the live production deployment. Is there a setting I can give to msiexec that will allow this? Is there a more suitable different approach I could use?

  • Filtering Filenames with bash

    I have a directory full of log files in the form ${name}.log.${year}{month}${day} such that they look like this: logs/ production.log.20100314 production.log.20100321 production.log.20100328 production.log.20100403 production.log.20100410 ... production.log.20100314 production.log.old I'd like to use a bash script to filter out all the logs older than x amount of month's and dump it into *.log.old X=6 #months LIST=*.log.*; for file in LIST; do is_older = file_is_older_than_months( ${file}, ${X} ); if is_older; then cat ${c} >> production.log.old; rm ${c}; fi done; How can I get all the files older than x months? and... How can I avoid that *.log.old file is included in the LIST attribute? Thank you Stefan

  • How to export Oracle statistics

    - by A_M
    Hi, I am writing some new SQL queries and want to check the query plans that the Oracle query optimiser would come up with in production. My development database doesn't have anything like the data volumes of the production database. How can I export database statistics from a production database and re-import them into a development database? I don't have access to the production database, so I can't simply generate explain plans on production without going through a third party hosting organisation. This is painful. So I want a local database which is in some way representative of production on which I can try out different things. Also, this is for a legacy application. I'd like to "improve" the schema, by adding appropriate indexes. constraints, etc. I need to do this in my development database first, before rolling out to test and production. If I add an index and re-generate statistics in development, then the statistics will be generated around the development data volumes, which makes it difficult to assess the impact my changes on production. Does anyone have any tips on how to deal with this? Or is it just a case of fixing unexpected behaviour once we've discovered it on production? I do have a staging database with production volumes, but again I have to go through a third party to run queries against this, which is painful. So I'm looking for ways to cut out the middle man as much as possible. All this is using Oracle 9i. Thanks.
