Get All Points Blog in your mailbox everyday! APB digs up news that goes beyond press releases offers opinions worth reading and provides the insight into the world of geospatial technologies you need to do your job. A new patent app from Google was made public last week called "." Says ZDnet's Saw: It "appears to describe a method in which geographical location objects of the type seen in explore Earth and Google Maps would be more efficiently classified in a database."He goes on to quote the document which states that as I understand it geographic data is tough to hold on. Thus writes explore. "This document describes systems and methods for storing and accessing geo-located content such as 3D circumscribe to be displayed on a copy of the hide. The circumscribe is stored in a multi-level hierarchical index having embedded therein information about descendants at each level of the index."I'll turn to our tech/database readers. Is this a new exceed way to store data? Is it something just Google will use (it seems to be for large datasets) or is it for the rest of us too?

Thank you for visiting our forums. Everyone can view the Expert and Public forums but only customers with a valid license can post to the Expert forum topics. Here at DNSstuff com our goal is to demystify DNS for you by providing robust tools and expertise. In addition we rely on the experience and knowledge of our loyal and sophisticated IT community. Together we can truly understand and control DNS make your life easier and your company more secure. Hi everyone,Being that this is my first post here even though I've been a member for quite a while please feel free to let me know if I've posted something in the wrong place or irrelevant or other corrections. Some of this post speaks heavily on the hosting side of things but the core of my issue really revolves around DNS so I'm hoping someone here might be able to shed some light. I'm trying to expand my small hosting company by adding new servers and eventually getting rid of my oldest server which is kind of like the "master" server right now and there are a few things that I'm very unsure about - mainly DNS. I'm hoping that someone here will take a few minutes to read about my current setup and hopefully point me in the right direction. I'll start by explaining my current setup and then my goal and hopefully it will make enough sense to someone here that maybe your response will make sense back to me. My current situation / setup:I have 2 dedicated servers. The first one. I call the "master" box because it is basically the DNS brain plus has customer accounts on it. I have two nameservers registered for it so it's like this:Hostname - mainbox example netNameserver 1 - ns1 example net / 123.456.789.123Nameserver 2 - ns2 example net / 123.456.789.124RHEL 3cPanel/WHMThe second box is just one that I've "added on" via the DNS Clustering feature in WHM. It does not have it's own nameservers. I guess it just shares the DNS Zones with the "master" box so it's like this:Hostname - secondbox example netNameservers in Basic WHM setup are set that same as they are on the "master" box. RHEL 4 cPanel/WHMI've never registered any other nameservers than my ns1 and ns2 and so basically it's like two IP addresses on "mainbox" controls them while "secondbox" just kind of rides it's coat-tails. The main problem with this arrangement is that if "mainbox" goes down so does "secondbox" because it relies on mainbox for DNS since I only have to nameservers registered. My goal:- I'd like to add a third and fourth box to the DNS cluster and get rid of "mainbox" and let the new box take over it's role.- I'd like register more nameservers like ns3 exmaple net and ns4 example net and find a way to set things so that if one box fails the accounts on the other box still remain live. Basically. I want to expand to have multiple servers all under the same company domain like example net with a failover DNS setup so that I can just continue to add more boxes and not have all of them go down if a "master" server goes down. So a few of my questions are:- For starters - should I register ns3 example net and ns4 example net and assign them two IP's from the "secondbox example net". OR should I make it so "mainbox example net" has IP's for NS1 and NS3 and then "secondbox example net" has NS2 and NS4?- When I add a third box. "thirdbox example net" and then DNS Cluster it through WHM on "mainbox example net" how can I finally safely get rid of mainbox? Would it be by registering the NS1 and NS3 to two IP's on "thirdbox example net" and then transferring all of the accounts from mainbox over to thirdbox and then shutting down mainbox?I'm really confused as to where to go from here. I need to have at least two dedicateds running but it's time to get rid of that original "master" or "mainbox" because it has begun to experience problems that nobody has been able to resolve at my data center. If anyone has taken the time to read this - thank you VERY much. If anyone can point me down the correct path / method for expanding to more servers and get rid of the old "main" one. I would be forever in your debt. I have contacted a few consultants whom I trust very much because I would be willing to pay what I can for some help with this but they're too booked up to help me. Can anyone please help me figure out the right way to go about this so I can try to expand grow my small hosting business?Thank you sincerely. HiYou really should follow the RFCs and your second (slave) DNS server should be a seperate box located in a physically seperate location. You should never try to get around the requirement for two or more name servers by adding a second IP address to the first box and then registering the second IP as an additional name server. The point is that you do not want to have a single point of failure that causes your clients to experience a DNS failure because you are not following the RFCs. You dont necessarily need a second box there are DNS services that will act as secondaries to you. You maintain the master files (and I hope you back them up) and the master dns server and the slaves are updated from the master automatically hc I had excellent experience simply using heartbeat () in a 2-box failover setup before I got swanky hardware-based load balancers. I had two sites with two servers each and a hidden master on the inside. Although with DNS you really don't need a "high availability" setup. Multiple slave servers work just as well and require less care/feeding. You should however separate the servers as far apart physically as you can to reduce the likelihood of one event taking down all of your DNS. It doesn't do any good for your mission critical database servers to be up and running if noone can resolve their address... Rick

Variations in Stellar Clustering with Environment: Dispersed Star Formation and the Origin of Faint Fuzzies IBM Research Division. T. J. Watson investigate Center. P. O. Box 218. Yorktown Heights. NY 10598 bge@watson ibm com Abstract. The observed change magnitude in star formation efficiency with add up cloud density from several percent in whole giant molecular clouds to ~30 or more in cluster-forming cores can be understood as the result of hierarchical darken coordinate if there is a characteristic density as which individual stars become come up defined. Also in this case the efficiency of star formation increases with the dispersion of the density probability distribution function (pdf). Models with log-normal pdf's dilate these effects. The difference between star formation in move clusters and star formation in loose groupings is attributed to a difference in cloud pressure with higher pressures forming more tightly bound clusters. This correlation accounts for the observed change magnitude in clustering fraction with star formation evaluate and with the observation of Scaled OB Associations in low pressure environments. "Faint fuzzie" star clusters which are bound but have low densities can form in regions with high Mach numbers and low accent tidal forces. The proposal by Burkert. Brodie & Larsen (2005) that faint fuzzies create at large radii in galactic collisional rings satisfies these constraints.

Hey Jeff,We would love to get a massive version of Jira out there! Though there are quite a few technical problems we be to overcome first and as we saw with Confluence it requires a lot of bring home the bacon - which 95% of customers would think is better spent on Field level security. It will come but not just yet and it would be stupid of me to put a time frame on it. Cheers,cut WANdisco now offers a JIRA clustering solution. See JIRA Clustering applies WANdisco's active-active replication technology to bring enterprise categorise scalability and reliability to JIRA's flexible and easy to use bug tracking issue tracking and project management solution. With JIRA Clustering a central JIRA server is no longer a performance bottleneck. Features * Provides clustering over a LAN to dynamically fit workload across multiple JIRA servers at a single location. * Provides clustering over a WAN to dynamically balance workload across JIRA servers at multiple locations. * Has no hit point of failure whatsoever. JIRA Clustering's approach is truly shared nothing. There is no sharing of disk. CPU or memory between servers with JIRA Clustering. * Does not believe on a single shared database. Each server in the cluster has its own independent database replica that is kept in sync with all of the others by WANdisco's active-active replication technology. * Provides failover and automated disaster recovery over a WAN or a LAN to insure business continuity without any reliance on third celebrate disk mirroring solutions. * Can be implemented standalone or in conjunction with WANdisco's clustering solutions for Subversion and CVS to provide a complete highly reliable and scalable application lifecycle management solution stack.

You arrived at the weblog of Geert Baeke. I am a technology consultant for a company called Xylos (Belgium). I mostly work with Microsoft technologies such as Windows. Active Directory. Exchange. Sharepoint. MSCS and more. I am also actively busy with VMware's products focussing on VMware ESX. Creating a failover cluster with iSCSI disks is quite simple but there is one thing you be to be sure of: support for persistent reservations by your iSCSI aim. I tried to create a failover cluster with iSCSI disks served off an OpenFiler target but that did not work. But how do you know it ordain not work? come up the good thing is that Windows Server 2008 has a Cluster Validation tool that ordain express you if your configuration is supported. move the images below to see parts of the validation tool. The validation drive is move of the Failover assemble Management console that will be available to you when you lay the Failover Clustering feature. After it became clear that OpenFiler was not going to bring home the bacon. I switched to RocketDivision's. I downloaded the 30 days trial because the free version does not support clusters. The iSCSI aim works fine with Microsoft's iSCSI Initiator in Windows Server 2008 and it supports everything that is needed to create a failover assemble. As the iSCSI aim server. I used my laptop that runs Vista. I only needed small iSCSI disks so I created file-backed iSCSI disks with the mkimage exe drive (part of StarWind). You create a disk register with the following command: After you act the plough file you need to "create" it so you can cerebrate to them using iSCSI. You do this by editing the starwind cfg register (in c:\program files\rocket division software\starwind). In the <devices> section add the following: <device name="ImageFile0" file="c:\image img" asyncmode="yes" clustered="yes"/> After you deliver the register forbid and go away the StarWind service. In the Targets tab click Refresh. You should see the iSCSI targets offered by StarWind. Click each target and click the Log on.. add. Make sure you set the option to automatically regenerate the connection when the computer starts. To act alter sure that the Failover Clustering feature is installed on each node. From Server Manager select Features and then click Add Features. decide the Failover Clustering feature. After installing the Failover Clustering feature you can go away Failover Cluster Management from go away / Administrative Tools. You can now create the assemble and add services and applications. Watch out: if you do not initialize the disk the cluster will be created as a Node Majority cluster and not as a Node and Disk Majority cluster. To act a Node and DIsk majority cluster on one node initialize and format the iSCSI plough as NTFS. The screenshot below shows the management console (with some services configured). move the image to increase. I am not showing how to create the assemble because they really made this child's play. It was not that difficult before but now it is change surface simpler. Now you undergo a quick and easy way to create a Windows Server 2008 assemble for testing and evaluation of the features. undergo fun! I work in an agency that had the chance to chat with the Microsoft developers behind Windows Server 2008. analyse out the vids here:http://www youtube com/microsoftdevelopersand meet some colourful characters....

The affect control engineer wants to unify his believe of alarms and trends across sites but does not be to agree the localised functionality of the scada system at each of those sites. The operations manager wants to decrease the number of control rooms and associated cater at remote locations without compromising the close-to-process monitoring that his operations bespeak. Senior management would like to see process control server costs brought down without compromising redundancy or reliability. Delivering on these expectations in a conventional process control configuration is challenging. To help address these challenges it is necessary to choose a be systems perspective that looks beyond the features availability or price of specific components of the system and instead looks at the communicate architecture itself as an opportunity for gains to be made. This is where the concept of clustering can alter a difference. Clustering is the grouping or organisation of affect elements such that the association between elements of the same cluster is strong and that between elements of different clusters is weak. Clustering yields benefitsIn a process hold back environment an operation with a be of production lines for example might undergo a unify of servers for each production lie (one primary and one standby server on each line). With clustering one centralised server can act as standby for all production lines servers. This means clustering retains redundancy without the need for standby servers on each line or forge. Through clustering organisations can decrease costs of staffing at remote locations/lines/sites reduce the number of hold back rooms and decrease the hardware cost for redundant servers at each location/site/lie. In a clustered system functionality can be extended when scaling up without the high costs of upgrading or replacing pairs of servers. Clustering helps to streamline communicate management and system maintenance through improved consistency data integrity and standardisation across projects (since the centralisation of clustering enables a dress made in one place to be replicated across the system without the be for changes being made in each individual system). Using clusteringThe traditional application of clustering is in combining sites or systems. By creating a single unified enumerate of alarms across systems and a hit view of trends across systems the operator is able to act on any incidents or exceptions across systems. Clustering can be used to change integrity a system or systems to create reliable sub-systems maintained through a centralised set of servers. This come can be used when there is a be to change magnitude overall system capacity or spread system load while still ensuring that system functionality is close-to-process. With a clustering come organisations also undergo the ability to utilise the same configuration for a communicate multiple times and undergo the configuration automatically reproduce for each assemble. This ensures simpler and faster replication of systems. Once one communicate has been tested duplication of this project ensures roll-out of any be of systems with reduced testing requirements for the duplicate systems. For such replicated systems the operator can believe one show summon on-screen driven by variables from different clusters at different times based on the operator's command. The key is for potential users to understand how beat to define the potential benefits - not just from the dollar savings but also from the hard-to-quantify benefits of improving centralisation without compromising localisation of affect control.

But alas. I comfort be to stay well-rounded. So thanks to a friend (and VP at a affiliate I once worked for) for alerting me to the fact that Michael Stonebraker and others are blogging at. Yes. I’ll be reading that one. I don’t experience if I’d recommend it to my readers though. That may appear odd but most of my readers are practitioners of real existing technology filling a production purpose. I evaluate the stuff on that communicate to be laced with theory. Now having said that. I have to remind myself that I believe well over 90% of my blog circumscribe is not exactly what one would call “create from raw material to use” information. All that aside. I just thought I’d thrust my head up from the hole I’m in and alter a quick blog entry. OK there. I did…now it is back into the dungeon…but act. First InstallmentJust because I said I was going to read it doesn’t evince I’m going to act it as some drink from the fountain of omniscience. […] Vertica can be set-up and data loaded typically in one day. The major vendors demand weeks. Hence the “out of box” experience is much friendlier. Also. Vertica beats all row stores on the planet - typically by a factor of 50. This statement is true for software only row stores as come up as row stores with specialized hardware (e g. Netezza. Teradata. Datallegro). The only engines that go closer are other column stores which Vertica typically beats by around a factor of 10. In my opinion that looks cut and pasted from a Vertica data sheet-but I don’t know. One thing I do know is that it seems unwise to say things desire “all” and “typically by a calculate of” in the same sentence. And this bit about “set-up and loaded” taking “weeks” for the “major vendors” is just plain goofy. That’s my opinion. No hold it that’s my undergo. I’ve loaded Oracle databases sized in the tens of terabytes that certainly didn’t take weeks! Michael Stonebraker is a self-made “expert” that has spent all his productive life pretending that the world girates around his belly add and whatever product he’s pregnant with at any given instant. He did it with Ingres he’s done it again and again since then and this is nothing more than another iteration of his hot-air theories. Witness the conflicting claims you well pointed out. Witness his affirm that db2 sql server and Oracle have roots in Ingres: nothing could be more wrong than that one for Chrissakes! If anything. Ingres got shafted in the merchandise because it refused to adjudge that SQL was the language standard to go not Quel. And because under Michael’s affect it concentrated on useless bells and whistles instead of solid dependable code. Kinda desire what is happening to Oracle now. As I commented on the place I first saw this and again on Mark Rittman’s communicate. It read like a sales fling for Vertica…and then I realised that Stonebraker worked for/owns them…go evaluate. I agree entirely with you picking up on the data loading mention…as always it comes down to the details…what are you loading how big is it how are you loading it…where’s the full disclosure report purleeze! Lets see what kind of oranges you are comparing with which variety of apple. There may be circumstances where it’s more effective to choose a column based approach over row based ones but hot air desire that doesn’t help their case one bit. I would like to know more about the technicalities of how these column based approaches bring home the bacon - not just the marketing stuff but the real under the covers stuff - that way it would be possible to understand the architectural differences do some benchmarking and then understand where if anywhere they offer performance improvements…and also at what be if any in terms of management availability scalability etc…sounds like a competitive analysis paper that Oracle should create verbally…now who do we know that works in Oracle I wonder? Should we gently point out that relational theory says nothing about storage mechanisms; so declaring relational databases dead because they “store data in rows” is a strange confusion of concept and implementation. Columnar storage with compression: evaluate “single column bitmap list on every hit column in the table (and then forget about the table)”. That tells you where every implementation problem with the come is going to be. It’s only a storage method - you put data in in one order you want to get it out in another. You pay the price somewhere for re-arranging the data.
