How to rename your computer/server name on EC2

E. Ravi — Tue, 17 Aug 2010 09:58:24 GMT

By default, the EC2config service will attempt to set your computer name for you. You can change this behavior by editing the Config.xml file inside your instance to have the element <Ec2SetComputerName> changed to Disabled. More information on this can be found here:

Sizing the network

Network sizing provides the most formulaic approach to Web server sizing and capacity planning. The goal of network sizing is to ensure that no bottleneck occurs between the Web server, the network cards, and network and client requests/response.

Determining the size of the network is based on the server use and characteristics. For example:

The amount/frequency of a request sent to the server (hits)
The size of that request (client request)
The size of the request (Web server response), total size of average Web page, including all objects

At a high level, basic network calculation can be expressed as follows:

bps = h x s

where:

b is the required network bandwidth per second (bits per second)
h is the number of Web server hits per second
s is the average size of each hit in bits

Bits and bytes

Networking components measure traffic differently from servers and storage components. Networking components usually measure traffic in bits/second, while servers and storage measure it in bytes/second. For example, a 100 Mbps network can transfer 12.5 MB per second. See calculations in Figure 1 . Figure 2 shows the utilization.

Figure 1. Calculating transfer rate for network

Figure 2. Network utilization

Finally, network overhead accounts for approximately 30 percent network utilization. This overhead results from all communications such as packet headers. Several vendors offer network card solutions that provide Transmission Control Protocol (TCP) acceleration; that is, network overhead can be off-loaded to a hardware card optimized for establishing and tearing down TCP connections.

Estimating number of hits

Accurate sizing requires a good estimate of the average number of hits per day. There are two approaches to estimating the number of hits per day. The first approach presumes that you have access to Web traffic information. In this case, calculate Web traffic and break the day into four-hour windows. Select the number of hits in the highest four-hour window. Multiply this figure by 6 (see Figure 3 ).

Figure 3. Web server traffic: 24 hours

Use the peak four-hour period as the reference point. Multiply it by 6 to determine hits per day. Then divide by 24 to determine hits per hour.

The second approach most likely applies to building an infrastructure from scratch, which requires a different set of steps. Identify the architecture of the Web site, including number of pages, objects per page, and the target customer. If it is an internal site on an intranet, your calculations can be based on the customer base and company or department size. If the Web site is an Internet site, talk with other people who have similar Web sites and can help you to estimate traffic characteristics.

Determining the processor size

Processor sizing is straightforward if steady state CPU utilization of less than 80 percent is assured. This is crucial to maintaining efficient response times, because the higher the CPU utilization, the longer the queue, and consequently, the longer the response time per request. If the CPU utilization is above 80 percent, queues grow exponentially rather than linearly. (See Little's Law for more information about queues).

Server-generated dynamic content, such as CGI or Java^TM servlets, makes it difficult to size the processor. The processing costs of this dynamic content will be high enough so that the Web server processing cost is not significant. This assumes that the Web server has been correctly configured.

Benchmarking data for the dynamic content generation processing that will be performed is essential. This data can be used to estimate the number of CPUs and CPU speed necessary to serve the dynamic content. This estimate requires an understanding of the proportion of hits that will cause dynamic content to be served to allow the average computational effort per hit to be calculated.

Sizing the memory

Knowing the resources to be used can help to determine the amount of memory required. For Web servers, consider the byte size of all the software resources running on the processor, beginning with the operating system. The Available Bytes counter can serve as a guide to the size of the unused portion of memory. Allow for 10 percent of memory to be free; this is also known as memory freespace.

As a rule of thumb, you can never have too much memory, because server performance degrades heavily when the system has insufficient memory. The amount of memory is generally a balance with the monetary cost. The availability of sufficient memory prevents the server from accessing the disk frequently. It also enhances the end-user experience while resulting in less work on the server.

If users request information that is stored in memory, that information can be retrieved directly from memory rather than accessing the disk.

To calculate memory requirements, add the required memory for the following consumers of RAM:

Operating system and Web server memory usage. See documentation for the applicable operating system and Web server to determine memory usage. In addition, remember that memory is directly affected by the number of concurrent connections.

Generating dynamic content. Generating dynamic content requires extra memory compared to serving static pages. If applicable, consider the amount of memory required to generate dynamic pages and the number of concurrent connections to estimate how much memory is required.

Calculating dynamic and static content ratios. When calculating the ratio of dynamic to static content served on a site, it is easy to overestimate the percentage of dynamic material, particularly because some content that appears dynamic is actually served as static content. A good rule of thumb is that dynamic content is loaded from a database, while static content loads from HTML, text, or other static types of files. Note that many Web sites today have a dynamic front-end and link to static pages. For example, visit www.microsoft.com and drill down a level or two and you will find Active Server^TM Pages (ASP) delivering the documents.

Financial sites that provide up-to-the-minute stock market quotations are good examples of a high dynamic content ratio. These sites typically provide 30-40 percent dynamic to 60-70 percent static content. Look closely at your site to assess the ratio of dynamic to static content.

Operating system and Web server caching. Two key types of caching are key to Web server performance: operating system file system caching and Web server caching. Be sure to allocate and account for memory for these processes. The system administrator usually controls these settings.

Putting it all together

Once the memory requirement is determined, this should be considered an absolute lower limit beyond which the server will fail. Add some contingency, then track the actual memory performance (especially the amount of disk access) when the site is implemented. Use the guidelines in Figure 4 .

Figure 4. Calculating lower limit of acceptable memory

Sizing the hard disk drive

Sizing the disk drives and number of drives is as important as determining memory and processor speed. It is important to never exceed 85 percent usage of disk drive space. Base the selection on 85 percent of used space and 15 percent free space. For example, with 8 GB of data: 8 (data size = GB) + 1.2 (15 percent free space based on 8 GB = 1.2) = 9.2. In this case, select one disk drive close to the 9.2 GB calculation or two smaller disks with capacity equal to 9.2.

Optimizing disk performance. Sizing and performance are not the same. Sizing is based on a conservative percentage of performance capabilities to allow for peaks and spikes in usage. Industry practice supports using no more than 80 percent of disk capacity and maintaining 20 percent of disk space for other network requirements. Choose the size of the disk based on the site size, considering the 80/20 ratio. However, Dell recommends employing a 60/40 ratio for multiple data centers-existing or planned for the future.

RAID

RAID (Redundant Array of Inexpensive Disks) is a disk subsystem that provides disk performance, reliability, or both. RAID is a set of two or more hard disks and a specialized disk controller that contains the RAID functionality.

The theory behind RAID is that instead of using one large drive to store all of the data, a set of smaller drives provides the flexibility to add redundancy and/or increase performance. There are many varieties of RAID, but the most commonly used RAID types are 0, 1, and 5.

RAID-0 offers better performance. RAID-0 is disk striping only, interleaving data across multiple disks for better performance. It does not provide safeguards against failure. For that reason, it is technically not "true" RAID because it does not provide fault tolerance. RAID-0 requires at least two hard disk drives (HDDs) and a RAID controller card.

RAID-1 provides high reliability. RAID-1 is disk mirroring that provides 100 percent duplication of data and provides a small performance benefit. Because both drives contain the same information, the RAID controller can read data from one drive while concurrently requesting data from the other drive. However, write speeds are slower since the controller must write all data twice. While RAID-1 offers high reliability, it doubles storage cost. The system will keep running if a hard disk fails. RAID-1 requires at least two HDDs and a RAID controller card.

RAID-5 provides both performance and fault tolerance. RAID-5 is one of the most commonly used RAID types. Data is striped across three or more drives for performance, and parity bits are used for fault tolerance. The parity bits from two drives are stored on a third drive. RAID-5 requires at least three HDDs and a RAID controller card.

Scalability, availability, and planning for growth

Business requirements increase over time. By adding processors, memory, and disks, Dell's PowerApp.web servers and general-purpose servers can scale up within each server, then scale out modularly. Businesses then have the option to scale their network by purchasing servers as needed, thereby realizing a return on investment (ROI) in a shorter time, rather than purchasing one large Web server and hoping to realize ROI.

Recent tests show that the PowerApp.web 120 Windows Powered systems were able to handle 1,110 concurrent users with 30,940 ASP request/minute with moderate load on the processors. See the article in Dell Power Solutions² for details.

Ubuntu 8.04 in Virtual PC 2007

E. Ravi — Thu, 19 Mar 2009 06:51:55 GMT

Installing Ubuntu 8.04 on the virtual machine

Once the virtual machine had been created, it should show up on your Virtual PC Console:

Start the Ubuntu VPC, and go to CD and choose Capture ISO Image and select the ISO image of Ubuntu. select the Language.

Choose English by Default and hit Enter.

Next, you have 5 options:

Try Ubuntu without any change to your computer "" this option is good when you are running Ubuntu from a live CD.
Install Ubuntu "" physical installation of Ubuntu on the physical hard disk
Check for CD Defects "" check if anything is wrong on the installation CD
Test Memory "" self explanatory, it checks the memory for any problem.
Boot from first hand hard disk.

Here I encountered an error when selecting the Install Ubuntu option:

An unrecoverable processor error has been encountered.

The virtual machine will reset now.

Here is the way around this problem. when you get to the option to unstall Ubuntu, press F4 and choose Safe graphics mode. then choose the first option on the menu:Try Ubuntu without any change to your computer.

If you still get the same problem do this:

At the prompt, press F4 and select "Safe graphics mode".
then press F6.

Modify the following boot line:

"Boot Options seed/ubuntu.seed boot=casper initrd=/casper/initrd.gz quiet splash -" Delete the part that says "quiet splash "" -" and replace it with "vga=791 noreplace-paravirt"

Sure - This option will make your Ubuntu boot onto the GUI. Now you start installing the ubuntu on to your local hard Drive

Click on the Install folder. The installation wizard should come up:

Select the language and click Forward. Next Choose your location: Continue the same and complete the installation.

here is the place you get into issue after successful installation of VPC Ubuntu.

When you reboot the VPC -

I got the dreaded error:

An unrecoverable processor error has been encountered. The virtual machine will reset now.

fix the booting problem.

When booting Ubuntu, press the Esc key when the GRUB loading is displayed. You should get 3 boot options menu:

Make sure, Ubuntu 8.04.1, Kernel 2.6.24-19-generic is selected, and press the letter E on your keyboard. You should get to the following window, with 3 options again:

Press the letter E again on your keyboard. on next window, delete the last piece of code that says "quiet splash "" """ and replace it with "noreplace-paravirt"

Press enter, you should get back to the previous window. Press B on your keyboard, Ubuntu should load fine now.

Now, we need to make this change permanently. After you logon to your Ubuntu GUI go to Applications then Accessories and open Terminal

Type the following command on terminal "sudo nano /boot/grub/menu.lst" enter you password when asked. When you get to the menu, scroll to the very bottom and look for the following code line:

Go to the end of the line code and change the last piece of code, from "quiet splash "" """ to "noreplace-paravirt" press CTRL + O to write, press ENTER to accept it, and press CTRL + X to exit out.

Now you have done the Successful installation of Ubuntu 8.04 on VPC 2007.

Thanks

How to Remove Vista from a Dual Boot system

E. Ravi — Tue, 13 Jan 2009 11:02:43 GMT

How to Remove Vista from a Dual Boot system

1. Boot your computer in to Windows XP.

2. Ensure you have the Vista DVD image emulated or in the DVD drive.

3. Go to Start and Run. Type in e:\boot\bootsect.exe /nt52 ALL /force (without quotes, and replacing e: with the drive letter of your Vista DVD).

4. Restart the computer, and you will notice the boot selection menu is gone.
Format the partition/drive where you had Vista installed.

5. Remove two files (Boot.BAK & Bootsect.BAK) on your XP drives root folder (C :), these were backup files of your previous boot loader, now no longer useful.

6. Optional: Restart to ensure it still works.

7. Use your partition software to merge your partitions together.

Now the complete system is out from vista and without the New Boot loader.

IIS 6.0: "Response buffer limit exceeded"

E. Ravi — Thu, 09 Nov 2006 08:01:52 GMT

Error message when a Web browser sends a request for an active server page to a Web server that is running IIS 6.0: "Response buffer limit exceeded"

http://support.microsoft.com/kb/925764

Increase the buffer limit You can increase the buffering limit if one of the following conditions is true:

•	The client is not a Web browser.
•	You cannot redesign the application to take advantage of a paging technology, such as the GridView class.

If you must increase the buffer limit, select a buffer limit that allows for the largest known response size. If you do not know the largest response size in advance, you can increase the buffer limit to a large value during testing. After you finish testing, use the largest value that is in the sc-bytes field in the IIS log file for the response that is generated for the page.

To increase the buffering limit, follow these steps:

1.	Click Start, click Run, type cmd, and then click OK.
2.	Type the following command, and then press ENTER: cd /d %systemdrive%\inetpub\adminscripts
3.	Type the following command, and then press ENTER: cscript.exe adsutil.vbs SET w3svc/aspbufferinglimit `LimitSize` Note `LimitSize` represents the buffering limit size in bytes. For example, the number 67108864 sets the buffering limit size to 64 MB.

To confirm that the buffer limit is set correctly, follow these steps:

1.	Click Start, click Run, type cmd, and then click OK.
2.	Type the following command, and then press ENTER: cd /d %systemdrive%\inetpub\adminscripts
3.	Type the following command, and then press ENTER: cscript.exe adsutil.vbs GET w3svc/aspbufferinglimit

How to calulate your bandwidth.

E. Ravi — Tue, 17 May 2005 12:15:28 GMT

The exact method to calculate your bandwidth....

do these things to calculate.
Create a file of 1mb and upload to your server, and keep a clock (stop watch) ready to count the seconds.
This method will give you the exact speed of your bandwidth.

File size = 1MB
Duration taken to download the file =35secs

Now let us calculate the bandwidth =    1MB      =1024KB
                                                     ____       ______
                                                      35sec      35

= (29.25 X 8)KB/s = 234Kbps

Your bandwidth is 234Kbps.

Upgrade your blog today to 1.7.X

E. Ravi — Sat, 19 Mar 2005 05:25:16 GMT

Blog 1.7.5016.2 has been released!

Those who have earlier versions can update their versions to 1.7 X now.
You can download the files from https://sourceforge.net/project/showfiles.php?group_id=127624.

Now how to upgrade the blog without any data loss. Upgrading from versions earlier than 1.7.5016.1.

Download these files from the above url.

Download the dasBlog-1.7.5016.2-Web-Files.zip
Download the dasBlog-1.7.5016.2-Upgrader.zip

Now let us see the steps how to upgrade.

Download your blog first and zip it as backup and also ensure -you have taken backup of your content, siteconfig,logs folders and web.config file, which carries your blog contents and config information.

Copy the Unzipped Dasblog 1.7 web files into the path.Copy the content, siteconfig,logs folders and web.config file from the backup to this folder.

Now run the dasblogupgrader.exe against your content folder.
Example : c:\dasblogupgrader.exe "D:\webistes\myblog\content"
BACKUP YOUR CONTENT FOLDER BEFORE RUNNING THIS!
Press ENTER to Continue...

Enter...

Make sure that all the entries are in the correct dayentry files. Some version of dasBlog placed them in the wrong files. This works by loading all your entries, backing up the old files in content\backup folder, and rewriting all the entries from an in memory cache.
Upgrade all the dayextra files because of a change in the file name to be a UTC file name (same as dayentry). The mismatch before caused some referrals, trackbacks and pingbacks to be lost due to the fact that dasBlog was using the UTC date of the dayentry file to look for the dayextra file and this resulted in no file found in many cases.
Set the IsPublic field on a all entries to true. dasBlog 1.7 finally uses this field to hide entries from everyone except the admin or any other authenticated users.
Delete any referral spam from your dayentry files (now named dayfeedback) using the keywords found in the DasBlogUpgrader.config file and entries in the MovableType Blacklist.

At this point you should have a local copy of all the dasBlog files needed, with your upgraded content folder, as well as your SiteConfig folder, and Web.config.

Now copy the files to your blog

Make sure on the server to delete the following
1. Delete the contents (not folders) of bin, content, logs, SiteConfig. Do not delete themes
2. Delete the folders ftb, images.
3. Delete all the files in the root web application (.aspx files, asmx files etc).
Copy the contents of your Unzipped Dasblog 1.7 web files to your remote server. Do not overwrite your logs folder.

Check: If you are running IIS 6 you must give NETWORKSERVICE the same permissions as ASPNET

Success!!! Now you are in to blog new version.Ensure the version newtelligence dasBlog 1.7.5016.2
