    - by ChuckO

  • Mysql ndb cluster - node restart.

    - by Arafat
    Hi guys! I just setup a mysql cluster on a fairly decent baby (IBM x3650 M3) with 24GB memory, xeon 6core, SAS 6Gbps HDD. Running Debian Lenny 5. 64bits. Ndb version is 7.1.9a. Our database size on MyISAM is around 3.2 GB. Ndb_size estimation is 58GB for ndbengine. A little info about my database is as follows. 150 common tables for global purpose. 130 tables for each clients. So it goes like this, 130 x 115(clients) = 14950 tables. Is it normal or usual to have 14000 tables on one database? The reasons why we did this was, Easy maintenance and per client based customization. Now, the problem is, ndb cluster can only support, 20320 tables. But it can support 5,000,000,000 rows in one table if I'm not wrong. My real head ache is my cluster data node takes less than two minutes to startup with out any data. But as soon as convert my tables into ndb, that too only 2000 tables, data node takes at least 30 to 40 mins to start up. Is it normal? If I convertt all my tables into ndb, will it take even longer? Or let's say if consolidate my 14000 table's data into one, which is 130 tables, will it help? Or is there anything idiotically wrong which I'm doing? I'll attach my config.ini file soon. here's the simple overview of my config Datamemory = 14G Indexmemory = 3GB Maxnooftable = 14000 Maxnoofattributes = 78000 I'm just testing these values with 2000 tables first. Please advise, how to increase the start up speed. Please point out where I'm going wrong. Thanks in advance guys!

  • VS2010 Developer Image

    - by David Ward
    I am about to create a new developer PC image for developing WPF applications using VS2010, WCF, SQL2008 and SharePoint2010. What OS should I opt for? Windows 7? Windows Server 2008 R2? I'd have thought Windows 7 to make sure that I have a similar experience during development as an end user, however I can't install SharePoint on a client OS and so thought about Windows Server 2008 R2 to help with the SharePoint development process. Thoughts?

  • Question about Displaying Documents and the CQWP in MOSS 2007

    - by Psycho Bob
    My organization is in the process of converting our intranet over to a SharePoint solution. Part of this intranet will be the movement and organization of all our internal documents. Currently, we have 11 pages of document links, each with its own subheadings. So far I have it set where each document has a custom field called "Page" with a check box list of all the document pages on the intranet site. On each individual page, I have setup a Content Query Web Part that displays the documents that have the corresponding Page value set (i.e. if a document Page value has been checked for "HR" it will appear on the HR page). The goal of this setup is to allow the nontechnical personal who will be responsible for the maintenance of the documents to be able to upload new documents to the documents list and note on which pages they should appear on without having to manually update the pages themselves. The problem that I am having is that I cannot seem to find a good way to sort the documents into their subheadings once they are on the appropriate page. I could create individual check boxes for each page/subheading combination, but this would create a list of approximately 50-75 items. Does anyone have any ideas as to how I could accomplish this, either via CQWP or by different means? Goals/Requirements of Installation Allow Intranet documents to be maintained by nontechnical personnel Display documents on the appropriate pages without user having to edit actual page or web part Denote document page location using user settable document attributes (if possible) Maintain current intranet organization and workflow Use only one document list without subdirectories NOTE: I am aware that this is not the most efficient or elegant way to do things, but these are the requirements I have been given for the project.

  • Managing multiple Apache proxies simultaneously (mod_proxy_balancer)

    - by Hank
    The frontend of my web application is formed by currently two Apache reverse proxies, using mod_proxy_balancer to distribute traffic over a number of backend application servers. Both frontend reverse proxies, running on separate hosts, are accessible from the internet. DNS round robin distributes traffic over both. In the future, the number of reverse proxies is likely to grow, since the webapplication is very bandwidth-heavy. My question is: how do I keep the state of both reverse balancers / proxies in sync? For example, for maintenance purposes, I might want to reduce the load on one of the backend appservers. Currently I can do that by accessing the Balancer-Manager web form on each proxy, and change the distribution rules. But I have to do that on each proxy manually and make sure I enter the same stuff. Is it possible to "link" multiple instances of mod_proxy_balancer? Or is there a tool out there that connects to a number of instances, and updates all with the same information? Update: The tool should retrieve the runtime status and make runtime changes, just like the existing Balancer-Manager, only for a number of proxies - not just for one. Modification of configuration files is not what I'm interested in (as there are plenty tools for that).

  • nginx error page and internal directives not working as expected

    - by Romain
    I'd like to setup my nginx server to return a specific error page on HTTP 50x status codes, and I'd like this page to be unavailable by a direct request from users (e.g., http//mysite/internalerror). For that, I'm using nginx's internal directive, but I must be missing something, as when I put that directive on my /internalerror location, nginx returns a custom 404 error (which isn't even my own 404 error page) when a page crashes. So, to summarize, here's what seems to happen: GET /Home nginx passes the query to Python I'm simulating an application bug to get the 502 error code nginx tries to return /InternalError from its error_page rule because of the internal rule, it finally fails back to a custom 404 error code <-- why? the documentation says error_page directives are not concerned by internal: http://wiki.nginx.org/HttpCoreModule#internal Here's an extract from nginx.conf with a few comments to point things out: error_page 404 /NotFound; error_page 500 502 503 504 =500 /InternalError; # HTTP 500 Error page declaration location / { try_files /Maintenance.html $uri @pythonbackend; } location @pythonbackend { include uwsgi_params; uwsgi_pass unix:///tmp/uwsgi.sock; } location ~* \.(py|pyc)$ { # This internal location works OK and returns my own 404 error page internal; } location /__Maintenance.html { # This one also works fine internal; } location ~* /internalerror { # This one doesn't work and returns nginx's 404 error page when I trigger an error somewhere on my site internal; } Thanks very much for your help!!

  • Can't find ant in the Android SDK

    - by StormShadow
    Hey all, I'm working my way through APress's Beginning Android 2 and I've made it all the way to chapter 3, where we build a skeleton app. The book tells me to compile my application by typing "ant" in the command line, but my pc doesn't know what "ant" is yet. I checked in the SDK files and it looks like it wasn't included with the Android SDK. Does anybody know where ant is? Thanks

  • linux Firewall question

    - by bcrawl
    I have few generic questions about firewalls and I thought the community up here could help me out. 1) So I recently installed Ubuntu server barebones. I checked for open ports, none were open which was great. Is that because there was a firewall installed or was it because there were no applications installed? 2) I installed some applications, (Apache, postgres,ssh, Java app and some few). Between these, I ended up opening a few ports (~10). Now I have a list of all the ports I would need open. So, how do I go about protecting them? [Is this the right question to ask? does the process go like this, Install Firewall - Allow Said needed ports - deny rest using IPtables rules] This is going to be open to the internet. Hosting low traffic ecommerce sites. 3) What do you think is the easiest way for me to quasi-secure the server, [low maintenance overhead/simplicity. Any open source "software" which can make my life easier?] 4) Finally, of the said open ports [2], I have 2 ports I need to close because they are telnet ports. Can I close these ports without installing a "firewall" Thanks all for the help and Merry Christmas!!!!!!!
