• Ruby PTY.spawn is Hanging - How to fill out Email and Password in simple example

  - by viatropos

  After asking this question, it looks like I need to use Ruby's PTY Module, of which there is no documentation. I have written this code to try to push content to Google App Engine because the python command sometimes asks me for my username and password. But when I run this code, it just hangs. cmd = "appcfg.py update cdn" PTY.spawn("#{cmd} 2>&1") do | input, output, pid | begin input.expect("Email:") do output.write("#{credentials[:username]}\n") end input.expect("Password:") do output.write("#{credentials[:password]}\n") end rescue Exception => e puts "GAE Error..." end end What am I missing here? How can I get this to work?

• Ruby and Forking

  - by Cory

  Quick question about Ruby forking - I ran across a bit of forking code in Resque earlier that was sexy as hell but tripped me up for a few. I'm hoping for someone to give me a little more detail about what's going on here. Specifically - it would appear that forking spawns a child (expected) and kicks it straight into the 'else' side of my condition (less expected. Is that expected behavior? A Ruby idiom? My IRB hack here: def fork return true if @cant_fork begin if Kernel.respond_to?(:fork) Kernel.fork else raise NotImplementedError end rescue NotImplementedError @cant_fork = true nil end end def do_something puts "Starting do_something" if foo = fork puts "we are forking from #{Process.pid}" Process.wait else puts "no need to fork, let's get to work: #{Process.pid} under #{Process.ppid}" puts "doing it" end end do_something

• Ruby Thread with "watchdog"

  - by Sergio Campamá

  I'm implementing a ruby server for handling sockets being created from GPRS modules. The thing is that when the module powers down, there's no indication that the socket closed. I'm doing threads to handle multiple sockets with the same server. What I'm asking is this: Is there a way to use a timer inside a thread, reset it after every socket input, and that if it hits the timeout, closes the thread? Where can I find more information about this? EDIT: Code example that doesn't detect the socket closing require 'socket' server = TCPServer.open(41000) loop do Thread.start(server.accept) do |client| puts "Client connected" begin loop do line = client.readline open('log.txt', 'a') { |f| f.puts line.strip } end rescue puts "Client disconnected" end end end

• Ruby Methods: how to return an usage string when insufficient arguments are given

  - by Shyam

  Hi, After I have created a serious bunch of classes (with initialize methods), I am loading these into IRb to test each of them. I do so by creating simple instances and calling their methods to learn their behavior. However sometimes I don't remember exactly what order I was supposed to give the arguments when I call the .new method on the class. It requires me to look back at the code. However, I think it should be easy enough to return a usage message, instead of seeing: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

• Code understanding, reverse engineering, best concepts and tools. Java.

  - by core07

  One of most demanding tasks for any programmer, architect is understanding other's code. E.g. I am contractor, hired to rescue some project very quickly. Fix bugs, plan global refactoring and therefore I need most efficient way to understand the code. What is the list of concepts, their priority and best tools for this? Of what I know: reverse code engineering to create object models (creating of diagram per package is not so convenient), create sequence diagrams (the tool connects in debug mode to the system and generates diagrams from runtime). Some visualizing techniques, using some tools to work not just with .java but also with e.g. JPA implementors like Hibernate. Generate diagram for not all the codebase, but add some class and then classes used by it. Is Sparx Enterprise Architect state of the art in reverse engineering or far from that. Any other better tools? Ideally would be that tool makes me understand the code as if I wrote it myself :)

• stripe payment issue ruby on rails

  - by Admir Huric

  So I have made a stripe payment option in my app. When I click the button pay now, it shows me that the payment is successful. and when I go to my stripe account and go to stripe-test and check logs, I can see my test payment with the code 200 OK. But this payment doesn't show in stripe-test events, or in stripe-test payments. Are the payments from logs processed the next day or am I doing something wrong? def charge Stripe.api_key = "some_test_api_key" customer = Stripe::Customer.retrieve(stripe_customer_id) if stripe_customer_id.nil? Stripe::Charge.create( :amount => 2500, :currency => "cad", :customer => stripe_customer_id, :description => "Usage charges for #{name}" ) end rescue Stripe::StripeError => e logger.error "Stripe Error: " + e.message errors.add :base, "Unable to process charge. #{e.message}." false end

• How to use OptionParse to allow only one flag

  - by dorelal

  There are only three ways to invoke install.sh ./install.sh ./install.sh --force ./install.sh -f I can write it easily. However I am trying to make use of OptionParse. This is what I have so far. def self.parse option = {} optparse = OptionParser.new do |opts| opts.banner = "Usage: ./install.sh [--force]" opts.on('-f', '--force', '') do |dir| option[:force] = true end end begin optparse.parse! rescue OptionParser::InvalidOption => e puts e end end How do I provide feedback to user in case user provides something other than -f or --force.

• Remove unncessary error raised by paperclip - filename is not recognized by the 'identify' command.

  - by kgpdeveloper

  I've been searching on how to solve this issue but could not find any real and working solution. User model: validates_attachment_content_type :avatar, :content_type = ['image/jpeg', 'image/pjpeg', 'image/x-png', 'image/png', 'image/gif'] Unnecessary error shows up when invalid file type is uploaded: Avatar /tmp/sample,23283,0.txt is not recognized by the 'identify' command. Server details: Ubuntu and Debian which identify results to /usr/bin/identify Specifying command path does not solve the issue: Paperclip.options[:command_path] = "/usr/bin" Any ideas? I looked at geometry.rb file and there seems to be something wrong with it. def self.from_file file file = file.path if file.respond_to? "path" geometry = begin Paperclip.run("identify", %Q[-format "%wx%h" "#{file}"[0]]) rescue PaperclipCommandLineError "" end parse(geometry) || raise(NotIdentifiedByImageMagickError.new("#{file} is not recognized by the 'identify' command.")) end Let me know if anyone has solved the same issue and how. Many thanks.

• Rendering another Action without changing URL?

  - by Michael Stum

  I have this code in my Rails 3 controller: def index now = Time.now.utc.strftime("%m%d") redirect_to :action => "show", :id => now end def show begin @date = Time.parse("12#{params[:id]}") dbdate = params[:id] rescue ArgumentError @date = Time.now.utc dbdate = @date.strftime("%m%d") end @date = @date.strftime("%B %d") @events = Event.events_for_date(dbdate) end So basically index is just a specialized version of show, hence I want it to execute show, render the show.html.erb view - but I do not want to change the URL like redirect_to does. I have tried this approach: def index now = Time.now.utc.strftime("%m%d") params[:id] = now show render :action => "show" end Now, this works, but it just smells badly. I'm new to Ruby and Rails, so I just wonder if there is something fundamentally wrong or if there is a better way to do this?

• Should I stick only to AWS RDS Automated Backup or DB Snapshots?

  - by James Wise

  I am using AWS RDS for MySQL. With it comes on backup, I understand that amazon provides two types of backup - automated backup and database (DB) snapshot. The difference is explain in here - http://aws.amazon.com/rds/faqs/#23. However, I am still confuse if should I stick to automated backup only or both automated and manual (db snapshots). What do you think guys? What's the setup of your own? I heard to others that automated backup is not reliable due to some unrecoverable database when the DB instance is crashed so the DB snapshots are the way to rescue you. If I will do daily DB snapshots as similar settings to automated backup, I have gonna pay much bunch of bucks. Hope anyone could enlighten me or advise me the right set up. Thanks. James

• Ruby execute code in class getting inherited to

  - by AdamB

  I'm trying to be able to have a global exception capture where I can add extra information when an error happens. I have two classes, "crawler" and "amazon". What I want to do is be able to call "crawl", execute a function in amazon, and use the exception handling in the crawl function. Here are the two classes I have: require 'mechanize' class Crawler Mechanize.html_parser = Nokogiri::HTML def initialize @agent = Mechanize.new end def crawl puts "crawling" begin #execute code in Amazon class here? rescue Exception => e puts "Exception: #{e.message}" puts "On url: #{@current_url}" puts e.backtrace end end def get(url) @current_url = url @agent.get(url) end end class Amazon < Crawler #some code with errors def stuff page = get("http://www.amazon.com") puts page.parser.xpath("//asldkfjasdlkj").first['href'] end end a = Amazon.new a.crawl Is there a way I can call "stuff" inside of "crawl" so I can use that exception handling over the entire stuff function? Is there a better way to accomplish this?

• Having difficulty catching postgresql exception in sequel/ruby

  - by mhd

  I have postgresql table that has somekind of unique constraint. I have ruby script that will update this table. The ruby script should be able to switch to UPDATE instead of INSERT when this kind of error occured: PGError: ERROR: duplicate key value violates unique constraint CMIIW, sequel seems cannot catch this exception?? Anyway,sample code below is something that I would like to see to work but apparently not: @myarray.each do |x| fresh_ds = DB["INSERT INTO mytable (id, col_foo) values ('#{x}' ,'#{myhash[x]}')"] result = fresh_ds.insert catch Sequel::Error do fresh_ds = DB["UPDATE mytable set col_foo = '#{myhash[x]} where id = #{x}"] result = fresh_ds.update end end Maybe my ruby code is wrong or I missed something I don't know. Any solution? Thanks. UPDATE: code below works, the error is caught when unique constraint is violated. @myarray.each do |x| begin # INSERT CODE rescue Sequel::Error # UPDATE CODE end end

• Ruby TCPSocket doesn't notice it when server is killed

  - by user303308

  I've this ruby code that connects to a TCP server (namely, netcat). It loops 20 times, and sends "ABCD ". If I kill netcat, it takes TWO iterations of the loop for an exception to be triggered. On the first loop after netcat is killed, no exception is triggered, and "send" reports that 5 bytes have been correctly written... Which in the end is not true, since of course the server never received them. Is there a way to work around this issue ? Right now I'm losing data : since I think it's been correctly transfered, I'm not replaying it. #!/usr/bin/env ruby require 'rubygems' require 'socket' sock = TCPSocket.new('192.168.0.10', 5443) sock.sync = true 20.times do sleep 2 begin count = sock.write("ABCD ") puts "Wrote #{count} bytes" rescue Exception => myException puts "Exception rescued : #{myException}" end end

• How do I conditionally assign ruby variables to javascript variables?

  - by Tony

  I have a website where I need a javascript version of the "current user" object along with the ruby version. I have been assigning these variables doing something like this... Application Controller: def get_user begin @current_user = User.find(session[:user_id]) if session[:user_id] @current_user_json = @current_user.to_json rescue session.delete(:user_id) @current_user = nil @current_user_json = {} end end Web Page: var current_user = null; current_user_json = '<%= @current_user_json %>'; if(current_user_json != ''){ current_user = current_user_json.user; } Even when there is a current user, I get the current user is undefined. Probably because I am putting the current_user_json assignment around single quotes. However, if I don't put it around single quotes, I'll always get a javascript error when no user is logged in because the syntax is invalid - current_user_json = ; I think I am just looking at this completely wrong and there must be a better way. Given that this is probably a common thing to do, I wanted to get other people's opinion on how to create an object in javascript that is a duplicate of the ruby object.

• Ruby: having callbacks on 'attr' objects

  - by JP

  Essentially I'm wondering how to place callbacks on objects in ruby, so that when an object is changed in anyway I can automatically trigger other changes: class MyClass attr_reader :proxy def proxy=(string_proxy = "") begin @proxy = URI.parse("http://"+((string_proxy.empty?) ? ENV['HTTP_PROXY'] : string_proxy)) @http = Net::HTTP::Proxy.new(@proxy.host,@proxy.port) rescue @http = Net::HTTP end end end m = MyClass.new m.proxy = "myproxy.com:8080" p m.proxy # => <URI: @host="myproxy.com" @port=8080> # However changing m.proxy will not change the @http variable, as proxy= is not being called. # Desired functionality: m.proxy = nil # Now @http.class is Net::HTTP, not Net::HTTP::Proxy

• Rails 2.3.5: flash[:notice] disappears after redirect_to call

  - by xyzman

  Here I've got two controller methods: def invite if request.post? begin email = AccountMailer.create_invite(@user,url) AccountMailer.deliver(email) flash[:notice] = "Invitation email sent to #{@user.email}" rescue #mail delivery failed flash[:error] = "Failed to deliver invitation" end redirect_to :action => :show, :id => @user.id end end and def show @title = "User #{@user.full_name}" end The problem is, when I send an invitation, and get redirected to ./show, I see no messages at all. If I change redirect_to to render, the message appears. Still, isn't it intended for flash to work in the immediate subsequent requests? BTW, I'm using Rails+Passenger setup, could it be so that redirected request goes to another application instance?

• Pattern for unidirectional has_many join?

  - by Kris

  It occurred to me that if I have a has_many join, where the foreign model does not have a belongs_to, and so the join is one way, then I don't actually need a foreign key. We could have a column, category_ids, which stores a marshaled Array of IDs which we can pass to find. So here is an untested example: class page < AR def categories Category.find(self.category_ids) end def categories<<(category) # get id and append to category_ids save! end def category_ids @cat_ids ||= Marshal.load(read_attribute(:category_ids)) rescue [] end def category_ids=(ids) @cat_ids = ids write_attribute(:category_ids, ids) end end page.category_ids = [1,4,12,3] page.categories = Array of Category Is there accepted pattern for this already? Is it common or just not worth the effort?

• Multiple HTTP request - Rails

  - by bradleyg

  My application checks a number of domains to see if they are valid (approx 100). I have the following code to check a single domain: def self.test_url uri, limit = 10 if limit == 0 return get_error_messages("001") end begin url = URI.parse(uri) response = Net::HTTP.start(url.host, url.port).request_head('/') rescue SocketError => e return get_error_messages("002") end case response when Net::HTTPRedirection then test_url(response['location'], limit - 1) else return get_error_messages(response.code) end end The code checks for the response code while taking into account redirects. This works fine. The only problem I have is when I put this in a loop I want it to run in parallel. So I don't have to wait for domain 1 to respond before I can request domain 2. I have managed this in PHP using curl_multi to run the requests in parallel. Is there a similar thing I can do in Rails?

• Slow NFS and GFS2 performance

  - by Tiago

  Recently I've designed and configured a 4 node cluster for a webapp that does lots of file handling. The cluster have been broken down into 2 main roles, webserver and storage. Each role is replicated to a second server using drbd in active/passive mode. The webserver does a NFS mount of the data directory of the storage server and the latter also has a webserver running to serve files to browser clients. In the storage servers I've created a GFS2 FS to hold the data which is wired to drbd. I've chose GFS2 mainly because the announced performance and also because the volume size which has to be pretty high. Since we entered production I've been facing two problems that I think are deeply connected. First of all, the NFS mount on the webservers keeps hanging for a minute or so and then resumes normal operations. By analyzing the logs I've found out that NFS stops answering for a while and outputs the following log lines: Oct 15 18:15:42 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:44 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:46 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:48 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:48 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:51 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:52 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:52 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:55 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:55 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:58 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK In this case, the hang lasted for 16 seconds but sometimes it takes 1 or 2 minutes to resume normal operations. My first guess was this was happening due to heavy load of the NFS mount and that by increasing RPCNFSDCOUNT to a higher value, this would become stable. I've increased it several times and apparently, after a while, the logs started appearing less times. The value is now on 32. After further investigating the issue, I've came across a different hang, despite the NFS messages still appear in the logs. Sometimes, the GFS2 FS simply hangs which causes both the NFS and the storage webserver to serve files. Both stay hang for a while and then they resume normal operations. This hangs leaves no trace on client side (also leaves no NFS ... not responding messages) and, on the storage side, the log system appears to be empty, even though the rsyslogd is running. The nodes connect themselves through a 10Gbps non-dedicated connection but I don't think this is an issue because the GFS2 hang is confirmed but connecting directly to the active storage server. I've been trying to solve this for a while now and I've tried different NFS configuration options, before I've found out the GFS2 FS is also hanging. The NFS mount is exported as such: /srv/data/ <ip_address>(rw,async,no_root_squash,no_all_squash,fsid=25) And the NFS client mounts with: mount -o "async,hard,intr,wsize=8192,rsize=8192" active.storage.vlan:/srv/data /srv/data After some tests, these were the configurations that yielded more performance to the cluster. I am desperate to find a solution for this as the cluster is already in production mode and I need to fix this so that this hangs won't happen in the future and I don't really know for sure what and how I should be benchmarking. What I can tell is that this is happening due to heavy loads as I have tested the cluster earlier and this problems weren't happening at all. Please tell me if you need me to provide configuration details of the cluster, and which do you want me to post. As last resort I can migrate the files to a different FS but I need some solid pointers on whether this will solve this problems as the volume size is extremely large at this point. The servers are being hosted by a third-party enterprise and I don't have physical access to them. Best regards. EDIT 1: The servers are physical servers and their specs are: Webservers: Intel Bi Xeon E5606 2x4 2.13GHz 24GB DDR3 Intel SSD 320 2 x 120GB Raid 1 Storage: Intel i5 3550 3.3GHz 16GB DDR3 12 x 2TB SATA Initially there was a VRack setup between the servers but we've upgraded one of the storage servers to have more RAM and it wasn't inside the VRack. They connect through a shared 10Gbps connection between them. Please note that it is the same connection that is used for public access. They use a single IP (using IP Failover) to connect between them and to allow for a graceful failover. NFS is therefore over a public connection and not under any private network (it was before the upgrade, were the problem still existed). The firewall was configured and tested thoroughly but I disabled it for a while to see if the problem still occurred, and it did. From my knowledge the hosting provider isn't blocking or limiting the connection between either the servers and the public domain (at least under a given bandwidth consumption threshold that hasn't been reached yet). Hope this helps figuring out the problem. EDIT 2: Relevant software versions: CentOS 2.6.32-279.9.1.el6.x86_64 nfs-utils-1.2.3-26.el6.x86_64 nfs-utils-lib-1.1.5-4.el6.x86_64 gfs2-utils-3.0.12.1-32.el6_3.1.x86_64 kmod-drbd84-8.4.2-1.el6_3.elrepo.x86_64 drbd84-utils-8.4.2-1.el6.elrepo.x86_64 DRBD configuration on storage servers: #/etc/drbd.d/storage.res resource storage { protocol C; on <server1 fqdn> { device /dev/drbd0; disk /dev/vg_storage/LV_replicated; address <server1 ip>:7788; meta-disk internal; } on <server2 fqdn> { device /dev/drbd0; disk /dev/vg_storage/LV_replicated; address <server2 ip>:7788; meta-disk internal; } } NFS Configuration in storage servers: #/etc/sysconfig/nfs RPCNFSDCOUNT=32 STATD_PORT=10002 STATD_OUTGOING_PORT=10003 MOUNTD_PORT=10004 RQUOTAD_PORT=10005 LOCKD_UDPPORT=30001 LOCKD_TCPPORT=30001 (can there be any conflict in using the same port for both LOCKD_UDPPORT and LOCKD_TCPPORT?)

I've also ran ping for a long time without any packet loss. MTU size is the normal 1500. As there is no VLan by now, this is the MTU used to communicate between servers. The webservers' network environment is similar. One thing I forgot to mention is that the storage servers handle ~200GB of new files each day through the NFS connection, which is a key point for me to think this is some kind of heavy load problem with either NFS or GFS2. If you need further configuration details please tell me. EDIT 3: Earlier today we had a major filesystem crash on the storage server. I couldn't get the details of the crash right away because the server stop responding. After the reboot, I noticed the filesystem was extremely slow, and I was not being able to serve a single file through either NFS or httpd, perhaps due to cache warming or so. Nevertheless, I've been monitoring the server closely and the following error came up in dmesg. The source of the problem is clearly GFS, which is waiting for a lock and ends up starving after a while. INFO: task nfsd:3029 blocked for more than 120 seconds.

• SQL SERVER – Fix : Error : 3117 : The log or differential backup cannot be restored because no files

  - by pinaldave

  I received the following email from one of my readers. Dear Pinal, I am new to SQL Server and our regular DBA is on vacation. Our production database had some problem and I have just restored full database backup to production server. When I try to apply log back I am getting following error. I am sure, this is valid log backup file. Screenshot is attached. [Few other details regarding server/ip address removed] Msg 3117, Level 16, State 1, Line 1 The log or differential backup cannot be restored because no files are ready to roll forward. Msg 3013, Level 16, State 1, Line 1 RESTORE LOG is terminating abnormally. Screenshot attached. [Removed as it contained live IP address] Please help immediately. Well I have answered this question in my earlier post, 2 years ago, over here SQL SERVER – Fix : Error : Msg 3117, Level 16, State 4 The log or differential backup cannot be restored because no files are ready to rollforward. However, I will try to explain it a little more this time. For SQL Server database to be used it should in online state. There are multiple states of SQL Server Database. ONLINE (Available – online for data) OFFLINE RESTORING RECOVERING RECOVERY PENDING SUSPECT EMERGENCY (Limited Availability) If the database is online, it means it is active and in operational mode. It will not make sense to apply further log from backup if the operations have continued on this database. The common practice during the backup restore process is to specify the keyword RECOVERY when the database is restored. When RECOVERY keyword is specified, the SQL Server brings back the database online and will not accept any further log backups. However, if you want to restore more than one backup files, i.e. after restoring the full back up if you want to apply further differential or log backup you cannot do that when database is online and already active. You need to have your database in the state where it can further accept the backup data and not the online data request. If the SQL Server is online and also accepts database backup file, then there can be data inconsistency. This is the reason that when there are more than one database backup files to be restored, one has to restore the database with NO RECOVERY keyword in the RESTORE operation. I suggest you all to read one more post written by me earlier. In this post, I explained the time line with image and graphic SQL SERVER – Backup Timeline and Understanding of Database Restore Process in Full Recovery Model. Sample Code for reference: RESTORE DATABASE AdventureWorks FROM DISK = 'C:\AdventureWorksFull.bak' WITH NORECOVERY; RESTORE DATABASE AdventureWorks FROM DISK = 'C:\AdventureWorksDiff.bak' WITH RECOVERY; In this post, I am not trying to cover complete backup and recovery. I am just attempting to address one type of error and its resolution. Please test these scenarios on the development server. Playing with live database backup and recovery is always very crucial and needs to be properly planned. Leave a comment here if you need help with this subject. Similar Post: SQL SERVER – Restore Sequence and Understanding NORECOVERY and RECOVERY Note: We will cover Standby Server maintenance and Recovery in another blog post and it is intentionally, not covered this post.

• Oracle Announces Oracle Exadata X3 Database In-Memory Machine

  - by jgelhaus

  Fourth Generation Exadata X3 Systems are Ideal for High-End OLTP, Large Data Warehouses, and Database Clouds; Eighth-Rack Configuration Offers New Low-Cost Entry Point ORACLE OPENWORLD, SAN FRANCISCO – October 1, 2012 News Facts During his opening keynote address at Oracle OpenWorld, Oracle CEO, Larry Ellison announced the Oracle Exadata X3 Database In-Memory Machine - the latest generation of its Oracle Exadata Database Machines. The Oracle Exadata X3 Database In-Memory Machine is a key component of the Oracle Cloud. Oracle Exadata X3-2 Database In-Memory Machine and Oracle Exadata X3-8 Database In-Memory Machine can store up to hundreds of Terabytes of compressed user data in Flash and RAM memory, virtually eliminating the performance overhead of reads and writes to slow disk drives, making Exadata X3 systems the ideal database platforms for the varied and unpredictable workloads of cloud computing. In order to realize the highest performance at the lowest cost, the Oracle Exadata X3 Database In-Memory Machine implements a mass memory hierarchy that automatically moves all active data into Flash and RAM memory, while keeping less active data on low-cost disks. With a new Eighth-Rack configuration, the Oracle Exadata X3-2 Database In-Memory Machine delivers a cost-effective entry point for smaller workloads, testing, development and disaster recovery systems, and is a fully redundant system that can be used with mission critical applications. Next-Generation Technologies Deliver Dramatic Performance Improvements Oracle Exadata X3 Database In-Memory Machines use a combination of scale-out servers and storage, InfiniBand networking, smart storage, PCI Flash, smart memory caching, and Hybrid Columnar Compression to deliver extreme performance and availability for all Oracle Database Workloads. Oracle Exadata X3 Database In-Memory Machine systems leverage next-generation technologies to deliver significant performance enhancements, including: Four times the Flash memory capacity of the previous generation; with up to 40 percent faster response times and 100 GB/second data scan rates. Combined with Exadata’s unique Hybrid Columnar Compression capabilities, hundreds of Terabytes of user data can now be managed entirely within Flash; 20 times more capacity for database writes through updated Exadata Smart Flash Cache software. The new Exadata Smart Flash Cache software also runs on previous generation Exadata systems, increasing their capacity for writes tenfold; 33 percent more database CPU cores in the Oracle Exadata X3-2 Database In-Memory Machine, using the latest 8-core Intel® Xeon E5-2600 series of processors; Expanded 10Gb Ethernet connectivity to the data center in the Oracle Exadata X3-2 provides 40 10Gb network ports per rack for connecting users and moving data; Up to 30 percent reduction in power and cooling. Configured for Your Business, Available Today Oracle Exadata X3-2 Database In-Memory Machine systems are available in a Full-Rack, Half-Rack, Quarter-Rack, and the new low-cost Eighth-Rack configuration to satisfy the widest range of applications. Oracle Exadata X3-8 Database In-Memory Machine systems are available in a Full-Rack configuration, and both X3 systems enable multi-rack configurations for virtually unlimited scalability. Oracle Exadata X3-2 and X3-8 Database In-Memory Machines are fully compatible with prior Exadata generations and existing systems can also be upgraded with Oracle Exadata X3-2 servers. Oracle Exadata X3 Database In-Memory Machine systems can be used immediately with any application certified with Oracle Database 11g R2 and Oracle Real Application Clusters, including SAP, Oracle Fusion Applications, Oracle’s PeopleSoft, Oracle’s Siebel CRM, the Oracle E-Business Suite, and thousands of other applications. Supporting Quotes “Forward-looking enterprises are moving towards Cloud Computing architectures,” said Andrew Mendelsohn, senior vice president, Oracle Database Server Technologies. “Oracle Exadata’s unique ability to run any database application on a fully scale-out architecture using a combination of massive memory for extreme performance and low-cost disk for high capacity delivers the ideal solution for Cloud-based database deployments today.” Supporting Resources Oracle Press Release Oracle Exadata Database Machine Oracle Exadata X3-2 Database In-Memory Machine Oracle Exadata X3-8 Database In-Memory Machine Oracle Database 11g Follow Oracle Database via Blog, Facebook and Twitter Oracle OpenWorld 2012 Oracle OpenWorld 2012 Keynotes Like Oracle OpenWorld on Facebook Follow Oracle OpenWorld on Twitter Oracle OpenWorld Blog Oracle OpenWorld on LinkedIn Mark Hurd's keynote with Andy Mendelsohn and Juan Loaiza - - watch for the replay to be available soon at http://www.youtube.com/user/Oracle or http://www.oracle.com/openworld/live/on-demand/index.html
