  • o2cb thinks ocfs2 cluster is still online, and refuses to shut down

    - by Kendall
    I have a handful of OpenSuSE 11.2 servers that utilize OCFS2 volumes. I've noticed that o2cb can't figure out when the OCFS2 cluster is actually mounted. For example, when I try to shutdown o2cb, after stopping OCSF2, o2cb refuses to shutdown because it thinks OCFS2 is still up! After stopping OCFS2 I try to stop o2cb... hamguy:/dev/disk/by-label # /etc/init.d/o2cb stop Stopping O2CB cluster ocfs2: Failed Unable to stop cluster as heartbeat region still active So I check the status... hamguy:/dev/disk/by-label # /etc/init.d/o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Stack glue driver: Loaded Stack plugin "o2cb": Loaded Driver for "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster ocfs2: Online Heartbeat dead threshold = 31 Network idle timeout: 30000 Network keepalive delay: 2000 Network reconnect delay: 2000 Checking O2CB heartbeat: Active And double check OCFS2... hamguy:/dev/disk/by-label # /etc/init.d/ocfs2 status Configured OCFS2 mountpoints: /u/conf /u/logs /u/backup /u/client /u/data /u/mdata OCFS2 is clearly down, while o2cb clearly thinks otherwise.

If I try to reboot the machine, it will just sit there forever until your physically power cycle it. That obviously is a bit of a problem. Any insight is appreciated, thank you. Kendall

  • Maintaining Revision Levels

    - by kyle.hatlestad
    A question that came up on an earlier blog post was how to limit the number of revisions on a piece of content. UCM does not inherently enforce any sort of limit on how many revisions you can have. It's unlimited. In some cases, there may be content that goes through lots of changes, but there just simply isn't a need to keep all of its revisions around. Deleting those revisions through the content information screen can be very cumbersome. And going through the Repository Manager applet can take time as well to filter and find the revisions to get rid of. But there is an easier way through the Archiver. The Export Query criteria in Archiver includes a very handy field called 'Revision Rank'. With revision labels, they typically go up as new revisions come in (e.g. 1, 2, 3, 4, etc...). But you can't really use this field to tell it to keep the top 5 revisions. Those top 5 revision numbers are always going up. But revision rank goes the opposite direction. The very latest revision is always 0. The previous revision to that is 1. Previous revision to that is 2. And so on and so forth. With revision rank, you can set your query to look for any Revision Rank greater or equal to 5. Now as older revisions move down the line, their revision rank gets higher and higher until they reach that threshold. Then when you run that archive export, you can choose to delete and remove those revisions. Running that export in Archiver is normally a manual process. But with Idc Command, you can script the process and have it run automatically from the server. Idc Command is a utility that allows you to run any of the content server services via the command line. You basically feed it a text file with the services and parameters defined along with the user to run it as. The Idc Command executable is located within the \bin\ directory: $ ./IdcCommand -f DeleteOlderRevisions.txt -u sysadmin -l delete_revisions.log In this example, our IdcCommand file to run the export and do the deletions would look like: IdcService=EXPORT_ARCHIVE aArchiveName=DeleteOlderRevisions aDoDelete=1 IDC_Name=idc dataSource=RevisionIDs <<EOD>> You can then use automated scheduling routines in the OS to run the command and command file at the frequency needed. Remember that you are deleting the revisions from within UCM, but they are still getting placed within the archive. So you will need to delete those batches to have them fully removed (or re-import if you need to recover them). For more information about Idc Command, you can find that in the Idc Command Reference Guide.

  • Forward all tracif from one IP to another Ip on OS X

    - by Josh
    This is related to this question I just asked... I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation. My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface. If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command. Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

  • EC2 EBS AMI Instance stopping/restarting doesn't start services

    - by tgm
    I've recently been moving our instances to EBS instances (CentOS) and still have a bit of confusion on what's happening when I "stop" and instance. I have some of my services with runlevels 345 on but when I start a stopped instance the services don't start. What's actually happening when I issue a stop command to the instance, and how do I get my services to start automatically when I start the instance up again?

  • 9 Ways Facebook Monetization Could Change Your Marketing

    - by Mike Stiles
    Think Facebook monetization isn’t a head game? Imagine creating something so functional, fun and addictive you literally amass about 1/7th of the planet’s population as an audience. You have 1 billion users that use it at least once a month. But analysts and marketers look at what you’ve done and say, “eh…not good enough.” What if you had a TV show that garnered 1/7 of Earth’s population as an audience? How much would a spot cost? And how fast would marketers write that check, even without the targeting and engagement analytics Facebook offers? Having already changed the marketing landscape forever, if you’re Facebook’s creator, you’d have to be scratching your head and asking, “Wow, what more does a product need to do?” Facebook’s been busy answering that very question with products and betas that will likely directly affect your brand’s strategy. Item 1: Users can send physical gifts to friends through Facebook based on suggestions from user data. A giant step toward the potential power of social commerce. Item 2: Users can pay $7 to promote posts for higher visibility. Individual users, not just marketers, are being leveraged as a revenue stream. Not impressive enough? There’s also the potential Craigslist killer Facebook Marketplace. Item 3: Mobile ads. 600 million+ access Facebook on smartphones. According to the company, half of the $1 million a day generated by Sponsored Stories as of late June was coming from mobile. Ads in News Feeds seen on mobile had click-through rates 23x higher than on desktop News Feeds or the right side panel. Item 4: App developers can buy install ads that show up in mobile News Feeds so reliance on discovery in app stores is reduced. Item 5: Want your posts seen by people who never liked your Page? A test began in August where you could appear in non-fans’ News Feeds on both web and mobile. Item 6: How about an ability to use Facebook data to buy ads outside of Facebook? A mobile ad network is being tested to get your targeted messages on non-Facebook apps and sites surfaced on devices. Item 7: Facebook Collections, Facebook’s answer to Pinterest. Users can gather images of desired products and click through to the retailer to buy. Keep focusing on your imagery. Item 8: Facebook Offers, Facebook’s answer to the Groupons and Living Socials of the world. You can send deals to your fans’ News Feeds. Item 9: Facebook Exchange lets you track what fans do on Facebook and across the entire Web. Could lead to a Facebook ad network leveraging Facebook users and data but not limiting exposure to the Facebook platform. Marketers are seeing increasing value in Facebook (and Twitter for that matter).  But as social grows and adjusts, will marketing budgets aimed in that direction grow and adjust accordingly, and within a reasonable time frame? @mikestilesPhoto Christie Merrill/stock.xchng

  • How-to dynamically filter model-driven LOV

    - by Frank Nimphius
    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Often developers need to filter a LOV query with information obtained from an ADF Faces form or other where. The sample below shows how to define a launch popup listener configured on the launchPopupListener property of the af:inputListOfValues component to filter a list of values. <af:inputListOfValues id="departmentIdId"    value="#{bindings.DepartmentId.inputValue}"                                          model="#{bindings.DepartmentId.listOfValuesModel}"    launchPopupListener="#{PopupLauncher.onPopupLaunch}" … >         … </af:inputListOfValues> A list of values is queried using a search binding that gets created in the PageDef file of a view when a lis of value component gets added. The managed bean code below looks this search binding up to then add a view criteria that filters the query. Note: There is no public API yet available for the FacesCtrlLOVBinding class, which is why I use the internal package class it in the example. public void onPopupLaunch(LaunchPopupEvent launchPopupEvent) {   BindingContext bctx = BindingContext.getCurrent();   BindingContainer bindings = bctx.getCurrentBindingsEntry();   FacesCtrlLOVBinding lov =        (FacesCtrlLOVBinding)bindings.get("DepartmentId");   ViewCriteriaManager vcm =   lov.getListIterBinding().getViewObject().getViewCriteriaManager();             //make sure the view criteria is cleared   vcm.removeViewCriteria(vcm.DFLT_VIEW_CRITERIA_NAME);   //create a new view criteria   ViewCriteria vc =          new ViewCriteria(lov.getListIterBinding().getViewObject());   //use the default view criteria name   //"__DefaultViewCriteria__"   vc.setName(vcm.DFLT_VIEW_CRITERIA_NAME);   //create a view criteria row for all queryable attributes   ViewCriteriaRow vcr = new ViewCriteriaRow(vc);   //for this sample I set the query filter to DepartmentId 60.   //You may determine it at runtime by reading it from a managed bean   //or binding layer   vcr.setAttribute("DepartmentId", 60);   //also note that the view criteria row consists of all attributes   //that belong to the LOV list view object, which means that you can   //filter on multiple attributes   vc.addRow(vcr);             lov.getListIterBinding().getViewObject().applyViewCriteria(vc); }  Note: Instead of using the vcm.DFLT_VIEW_CRITERIA_NAME name you can also define a custom name for the view criteria.

  • XBMC launching external applications full screen

    - by Aquadisco
    Running xbmc-standalone (Eden) on Ubuntu server edition 12.04 (no gnome/kde/etc...). When launching another application via 'advanced launcher' or other launcher add-on XBMC goes into a 'windowed mode' and the app shows up in a 'windowed' mode. The XBMC and app windows are cascaded and most of the screen is unused. This is obviously not what i'd like. I'd like the app to launch full screen. ideas? Other info: - using lightdm - tried with 'Rom Browser' - tried with 'Advanced Launcher' - once app had launched, tried to 'toggle full screen' in app, but with no success

  • The Oscar of Java Programming

    - by Tori Wieldt
    Why bother nominating a peer, yourself or your company for a Duke's Choice Award? I asked Duke's Choice Award winner Fabiane Nardon, whose team won in 2005 for the Healthcare Information System they created for the Brazilian government, what it was like winning the award and if it had any impact on her career. Here's what she told me: 1) What was it like to win a Duke's Choice Award? For me it was like winning an Oscar or a Grammy :-) I think that for a Java developer, a Duke's Choice Award is probably the highest award you can get, so it was really an honor. We had an amazing team working on that project and the team really deserved it. We were all very happy when we got that email with the announcement. That moment was one of the most important moments of my career. 2) What benefits have you gotten from being a "Duke's Choice Award Winner?" I think the most important benefit you get from winning a Duke is the fact that you become known by your peers. This opens many doors, since you are approached by more people, get invitations to speak in more conferences, you meet people with the same technical interests you have and so on. I certainly benefited a lot from it. We were lucky that in 2005, when we got our award, the winners were featured in the JavaOne keynote, with short documentaries produced about each one. So, we could be on the stage and talk a little about the project. We got lots of press at the time. We see  today's winners benefiting a lot from the press coverage. 3) How is the the Brazilian Healthcare Information System project doing today? Still running and getting new features every year. I'm not involved on the project anymore, but there are good people taking care of it. We opened the code since the beginning, so different cities could use and add features to it. There are many new developers working on that code base right now and I hope they can take the whole system to a new level. 4) What are you up to these days? I worked in the healthcare field for many years and a few years ago I decided that it was time to move on and take the experience I got designing large scale and mission critical systems to other fields. Since then I have been working with high access internet applications. I also co-founded ToolsCloud, a company that provides a development environment with open source tools in the cloud. We just launched ToolsCloud in USA, so other companies can get the same bundle of tools, hassle free, that several companies are successfully using in Brazil. Besides that, right now I'm personally working on the coolest project I ever worked on. It combines several technical challenges with a good dose of social impact. We should launch it in the second semester and I should keep it as a secret for now. Hopefully it will be useful to many people and disruptive enough to maybe get us a new Duke's Choice Award. Who knows? Read more about Fabiane in the "Heroes of Java" series by Markus Eisele. Her Twitter handle is @FabianeNardon. The Duke's Choice Awards celebrate extreme innovation in the world of Java technology. Nominate an individual, a group or company who show the best in Java innovation. Nominate via the easy online form at www.Java.net/dukeschoice. Nominations are open until June 15, 2012.

  • Cent OS ifcfg configuration for ranges of IP's with different netmask

    - by Aaron Schlegel
    I have 1 set of 30 public IP's with a netmask of 255.255.255.0 and another set of 30 IP's with a netmask of 255.255.255.128. Both sets of IP's also have different gateways. How can I virtually assign the IP's to the machine? I have tried creating ifcfg-eth0:0 ifcfg-eth0:1 ifcfg-eth0:X ect for each IP. Below is my ifcfg file with. I have this for each IP with the correct gateway IP and netmask for each of my 60 IP's. If I do ip addr show it does show all of the 60 addresses with the correct broadcast IP and netmask. However I can only use 30 of my IP's that are from the same netmask. Am I doing this correctly? If the IP's show up with ip addr show does that mean I have correctly assigned them to the machine virtually? I want to check before I blame my hosting company for not routing the IP's correctly. DEVICE="eth0:1" BOOTPROTO="static" DNS1="**.**.**.**" DNS2="**.**.**.**" GATEWAY="2**.**.***.126" HOSTNAME="localhost.localdomain" HWADDR="0*:19:**:**:**:**" IPADDR="2**.*.**.**" IPV6INIT="no" MTU="1500" NETMASK="255.255.255.128" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" Also is there a better way to do this? I have used ifcfg-eth0:0-range1 before to assign a range of IP's from the same netmask. Is it possible to do this with ranges with different netmask? Thanks!

  • KVM guest io is much slower than host io: is that normal?

    - by Evolver
    I have a Qemu-KVM host system setup on CentOS 6.3. Four 1TB SATA HDDs working in Software RAID10. Guest CentOS 6.3 is installed on separate LVM. People say that they see guest performance almost equal to host performance, but I don't see that. My i/o tests are showing 30-70% slower performance on guest than on host system. I tried to change scheduler (set elevator=deadline on host and elevator=noop on guest), set blkio.weight to 1000 in cgroup, change io to virtio... But none of these changes gave me any significant results. This is a guest .xml config part: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/vgkvmnode/lv2'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> There are my tests: Host system: iozone test # iozone -a -i0 -i1 -i2 -s8G -r64k random random KB reclen write rewrite read reread read write 8388608 64 189930 197436 266786 267254 28644 66642 dd read test: one process and then four simultaneous processes # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct 1073741824 bytes (1.1 GB) copied, 4.23044 s, 254 MB/s # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 14.4528 s, 74.3 MB/s 1073741824 bytes (1.1 GB) copied, 14.562 s, 73.7 MB/s 1073741824 bytes (1.1 GB) copied, 14.6341 s, 73.4 MB/s 1073741824 bytes (1.1 GB) copied, 14.7006 s, 73.0 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 6.2039 s, 173 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 32.7173 s, 32.8 MB/s 1073741824 bytes (1.1 GB) copied, 32.8868 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9097 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9688 s, 32.6 MB/s Guest system: iozone test # iozone -a -i0 -i1 -i2 -s512M -r64k random random KB reclen write rewrite read reread read write 524288 64 93374 154596 141193 149865 21394 46264 dd read test: one process and then four simultaneous processes # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 1073741824 bytes (1.1 GB) copied, 5.04356 s, 213 MB/s # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 24.7348 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7378 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7408 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.744 s, 43.4 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 10.415 s, 103 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 49.8874 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8608 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8693 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.9427 s, 21.5 MB/s I wonder is that normal situation or did I missed something?

  • how to uninstall mariadb and re-install mysql ? Mysql install turns into mariadb install

    I recently upgraded my centos system via the desktop. mistake! I had mariadb, phpmyadmin working just fine before - but after the upgrade they stopped.

    Hello, I have a big problem with installing a certificat for nginx (same happends with apache though) I have 3 files __domain_com.crt __domain_com.ca-bundle and ssl.key. I tried to append cat __domain_com.crt __leechpack_com.ca-bundle bundle.crt but if I do it like this i get an error: [emerg]: SSL_CTX_use_certificate_chain_file("/etc/nginx/__leechpack_com.crt") failed (SSL: error:0906D066:PEM routines:PEM_read_bio:bad end line error:140DC009:SSL routines:SSL_CTX_use_certificate_chain_file:PEM lib) And that's because the delimiters of the certificates arren't separated.

  • Media Temple-like hosting services?

    - by antonpug
    I have a couple of wordpress sites which do not get much traffic now, but I plan on expanding to something like a 1000-2000visits/day in a year or two. Media Temple has some really nice offerings, but their Wordpress plan is 20/month...which is a little too much, seeing as at this point my site is more of a hobby than a money making machine. I currently host with HostGator (just switched from GodaddyiPageBluehost). All these cheaper/pop hosting services are okay, but it would be nice to find something a little bit more "premium", but at a lower cost than MT. Anyone know anything worth looking at?

  • Where in the user profile are the Firefox search engine choices stored?

    - by N Rahl
    We have a large number of user profiles that were created on Ubuntu 10.04 and they had access to Google as a choice in the search bar and Google was the provider for queries typed into the super bar. When logging into these same profiles from Mint 15 client machines, the Google search option does not exist for these users, as is the default for Mint. This setting seems to be user specific, but not a part of the FireFox profile? It seems if it were a part of the FF profile, it would "just work" on Mint for these profiles, so I suspect the configuration may be stored somewhere else in the user's profile? Could someone please tell me where in a user's profile the search engine options are set? We would like to set this once, and then drop this configuration into everyones profile so all of our users don't have to do this manually.

  • debian modem problems !!!

    - by Raafat
    hay there guys ... I'm a new Debian user, it looks like a very good choice 4 me, every thing is stable, free and easy to use. the problem is, I'm using my modem to establish a dial up connection to the internet (ppp) (a very old stupid way I'm forced to use for now), and using the KPPP application to do that, and nothing is working properly for me. it seems like it didn't recognize my modem or something. i already tried to make a few stuff, and now i know my modem is on /dev/tty0, so i made a link for that on /dev/modem, and query the modem using KPPP and it responded with something like: Ati : Ati0: Ati1: ... ... Ati7: with a textBox to fill up in front of each one of thees Atis, and now, when i press connect on kppp, it says modem ready, and that's it. BTW, my modem is MDC AC'97 any suggestions pleas ....

  • How to boot between OSes from inside each OS? in a Windows/Ubuntu dual boot system

    - by TheCompander
    My ideal scenario is that there is a script/command to boot into the alternate OS from the current OS you are in, restarting the same OS without running the script/command will return it to the same OS. Currently I have grub setup to remember the last OS booted, using GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true, I'd like to keep this option. I have read about the ability to manipulate grub from within Ubuntu to boot into windows, shown in this link. Is there a way to similarly boot into Ubuntu from within Windows? I am primarily connecting to this device remotely and hence my query.

  • pam_filter usage prevent passwd from working

    - by Henry-Nicolas Tourneur
    Hello everybody, I have PAM+LDAP SSL running on Debian Lenny, it works well. I always want to restrict who's able to connect, in the past I used pam_groupdn for that but I recently got a situation where I has to accept 2 different groups. So I used pam_filter like this : pam_filter |(groupattribute=server)(groupattribute=restricted_server) The problem is that with this statement, passwd doesn't work anymore with LDAP accounts. Any idea why ? Please find hereby some links to my config files : Since serverfault.com only allow me to post 1 link, please find hereunder the link to other conf files : http://pastebin.org/447148 Many thanks in advance :)

    As a sales or marketing executive, you want the best software for managing your marketing, demand generation, trade promotion, customer/volume planning, and retail execution/monitoring activities and analysis. However, working with niche software vendors can result in a very disjointed user and support experience. It would be ideal to have just one end-to-end solution that could manage and optimize each of these processes...but is that just wishful thinking? Read this Gartner article to find out more!

  • MySQL Cluster 7.2: Over 8x Higher Performance than Cluster 7.1

These enhancements are summarized in the Figure below, and detailed in the MySQL Cluster New Features whitepaper Figure 1: Next Generation Web Services, Cross Data Center Replication and Ease-of-Use Once of the key enhancements delivered in MySQL Cluster 7.2 is extensions made to the multi-threading processes of the data nodes. Multi-Threaded Data Node Extensions The MySQL Cluster 7.2 data node is now functionally divided into seven thread types: 1) Local Data Manager threads (ldm). Note – these are sometimes also called LQH threads. 2) Transaction Coordinator threads (tc) 3) Asynchronous Replication threads (rep) 4) Schema Management threads (main) 5) Network receiver threads (recv) 6) Network send threads (send) 7) IO threads Each of these thread types are discussed in more detail below. MySQL Cluster 7.2 increases the maximum number of LDM threads from 4 to 16. The LDM contains the actual data, which means that when using 16 threads the data is more heavily partitioned (this is automatic in MySQL Cluster). Each LDM thread maintains its own set of data partitions, index partitions and REDO log. The number of LDM partitions per data node is not dynamically configurable, but it is possible, however, to map more than one partition onto each LDM thread, providing flexibility in modifying the number of LDM threads. The TC domain stores the state of in-flight transactions. This means that every new transaction can easily be assigned to a new TC thread. Testing has shown that in most cases 1 TC thread per 2 LDM threads is sufficient, and in many cases even 1 TC thread per 4 LDM threads is also acceptable. Testing also demonstrated that in some instances where the workload needed to sustain very high update loads it is necessary to configure 3 to 4 TC threads per 4 LDM threads. In the previous MySQL Cluster 7.1 release, only one TC thread was available. This limit has been increased to 16 TC threads in MySQL Cluster 7.2. The TC domain also manages the Adaptive Query Localization functionality introduced in MySQL Cluster 7.2 that significantly enhanced complex query performance by pushing JOIN operations down to the data nodes. Asynchronous Replication was separated into its own thread with the release of MySQL Cluster 7.1, and has not been modified in the latest 7.2 release. To scale the number of TC threads, it was necessary to separate the Schema Management domain from the TC domain. The schema management thread has little load, so is implemented with a single thread. The Network receiver domain was bound to 1 thread in MySQL Cluster 7.1. With the increase of threads in MySQL Cluster 7.2 it is also necessary to increase the number of recv threads to 8. This enables each receive thread to service one or more sockets used to communicate with other nodes the Cluster. The Network send thread is a new thread type introduced in MySQL Cluster 7.2. Previously other threads handled the sending operations themselves, which can provide for lower latency. To achieve highest throughput however, it has been necessary to create dedicated send threads, of which 8 can be configured. It is still possible to configure MySQL Cluster 7.2 to a legacy mode that does not use any of the send threads – useful for those workloads that are most sensitive to latency. The IO Thread is the final thread type and there have been no changes to this domain in MySQL Cluster 7.2. Multiple IO threads were already available, which could be configured to either one thread per open file, or to a fixed number of IO threads that handle the IO traffic. Except when using compression on disk, the IO threads typically have a very light load. Benchmarking the Scalability Enhancements The scalability enhancements discussed above have made it possible to scale CPU usage of each data node to more than 5x of that possible in MySQL Cluster 7.1. In addition, a number of bottlenecks have been removed, making it possible to scale data node performance by even more than 5x. Figure 2: MySQL Cluster 7.2 Delivers 8.4x Higher Performance than 7.1 The flexAsynch benchmark was used to compare MySQL Cluster 7.2 performance to 7.1 across an 8-node Intel Xeon x5670-based cluster of dual socket commodity servers (6 cores each). As the results demonstrate, MySQL Cluster 7.2 delivers over 8x higher performance per data nodes than MySQL Cluster 7.1. More details of this and other benchmarks will be published in a new whitepaper – coming soon, so stay tuned! In a following blog post, I’ll provide recommendations on optimum thread configurations for different types of server processor. You can also learn more from the Best Practices Guide to Optimizing Performance of MySQL Cluster Conclusion MySQL Cluster has achieved a range of impressive benchmark results, and set in context with the previous 7.1 release, is able to deliver over 8x higher performance per node. As a result, the multi-threaded data node extensions not only serve to increase performance of MySQL Cluster, they also enable users to achieve significantly improved levels of utilization from current and future generations of massively multi-core, multi-thread processor designs.

  • What is the best distro to host a KVM virtualization solution

    - by elventear
    I am looking for a Server oriented distro that we can expect have decent support but also offer as much as possible some of the latest features that KVM might offer. I am leaning towards Ubuntu LTS 10.04, because well it's LTS and more bleeding edge, but I find Ubuntu not serious enough in terms of support (I say this a heavy Ubuntu user). Given that Centos 6 is not out yet, I am not sure if going Centos 5 would be the best option in terms of getting more features from KVM. Any other distro you would recommend that could meet the criteria of long term support? (At least 4 years)
