How to use the Move Mailbox tool in Exchange Server 2003

If the Move Mailbox tool is multithreaded, how many threads can it create at the same time? How many mailboxes can the Mailbox Move tool move at the same time?

Can the Move Mailbox tool move mailboxes between earlier versions of Exchange, or can it only move mailboxes to or from Exchange 2003?

Can a mailbox move operation still be done from Exchange Tasks in Active Directory Users and Computers ?


This section provides exchange 2003 server support for how to use the new functionality of the Move Mailbox tool.

1. In Exchange 2003, start Exchange System Manager, select the mailboxes that you want to move (or select the users in Active Directory Users and Computers), and then click Exchange Tasks.
2. When the Exchange Task Wizard appears, click Move Mailbox , and then click Next.
3. Select the server and the mailbox store that you want to move the mailboxes to, and then click Next.
4. Click the action that you want the Move Mailbox tool to take if corrupted items are encountered during the mailbox move, and then click Next.
5. Select the start time and the finish time for the mailbox move, and then click Next.
6. The mailbox move is now underway. Note that all the selected mailboxes are moved at the same time (the percent of messages that have been moved increases on all the selected mailboxes at the same time).
7. After the mailbox move is complete, Exchange Task Wizard displays a summary of results of the task. If you want to view a detailed report of the Move Mailbox task, click to select the View detailed report when this wizard closes check box, and then click Finish.

Summary In this Server Support tips is used To use Exchange 2003 management tools, the schema must be updated by installing an Exchange 2003 server. Or, if you are using Exchange 2003 ESM or ADUC without having installed an Exchange 2003 server, you need to run Exchange 2003 Setup by using the /forestprep switch. If you do not update the schema, Move Mailbox will not work correctly.

What is Clustering and Load Balancing?

Clustering is often understood to mean the capability of some software to provide load balancing services, and load balancing is often used as a synonym for a hardware- or third-party-software-based solution.

In practice, clustering is usually used with application servers like IBM WebSphere, BEA WebLogic and Oracle AS (10g). Also being used in that environment are load balancing features found in Application Delivery Controllers (ADC) like BIG-IP. (For simplicity, we will talk about "clustering" versus "ADC" approaches.)

Scalability

There are hardware load balancers, of course, but there we talk about "pools" or "farms," the server groupings where application requests get distributed. It is in the software world that the term "cluster" is applied to that same group.

Clustering will typically convert one instance of an application server to a master controller, then process/distribute requests to multiple instances using such industry standard algorithms as round robin, weighted round robin or least connections. Clustering is similar to load balancing in that it has horizontal scalability, a nearly transparent way to add additional instances of application servers for increased capacity or response time performance. To ensure that an instance is actually available, clustering approaches typically use an ICMP ping check or, sometimes, HTTP or TCP connection checks.

Health and Transparency

For load balancing, ADCs support the same industry algorithms, but have additional, complex number-crunching processes, and check such parameters as per-server CPU and memory utilization, fastest response times, etc. ADCs also support more robust health monitoring than the simple app server clustering solutions. This means they can verify content and do passive monitoring, dispensing with even the low impact of health checks on app server instances.

For applications that require the user to interact with the same server during a session, clustering uses server affinity to get the user there. This is most common during the execution of a process like order entry, where the session is used between pages (requests) to store data needed to close a transaction, like a shopping cart.

For the same situation, ADCs use persistence. Clustering solutions are usually somewhat limited as to the variables they can use, while ADCs can not only use traditional application variables but also get other information from the application or network-based data.

More than a few clustering solutions need node-agents deployed on each instance of an application server that is "clustered" by a controller. It may not be a burden as far as deploying and managing it, since it is often in place, but it is still means more processes running on the servers and consuming memory and CPU resources. Of course, it also adds another possible failure point to the data path. Since ADCs need no server-side components, they remain completely transparent.

What is Cluster Hosting?

Having a web site is a necessity for the success of most businesses in today's technologically advanced society. However, just having a web site doesn't mean that it is going to get the public exposure needed to be successful. That is where web hosting comes into play. With web hosting you rent a place in a server and exposure to the internet. The pricing of web hosting can range anywhere from the bare minimum for free to the most advanced for a varied prices depending on the web hosting company and the type of web hosting you decide to go with.

One type of web hosting that works toward getting exposure to your web site, but is somewhat less common than other types of web hosting is Cluster Hosting. The configuration of cluster hosting tends to lean more toward more complex design, implementation and support. Networking of shared resources of computing, as well as varied implementations of those resources comprises a cluster. It is often referred to as a server farm since is consists of a group of independent servers. However, the group functions together toward a common goal.

If a company experiences an IT system failure, there can be a lot of money lost while the website is down. This is where cluster hosting comes into play. When connected directly to a single server, if failure occurs the user cannot reconnect; whereas with a cluster the user can immediately reconnect and keep going with what they were doing. If one server of a cluster host would happen to fail, there is an automatic backup.

A complex cluster can take data and split it into manageable sections that independent servers can then process. In this way if a single server should fail there is no affect to the others. There are a couple of different kinds of cluster configurations in cluster hosting as well. These include an active/passive cluster and active/active cluster. The active/passive situation involves a passive server being idle until the case where the active server fails. If the active server fails, the passive server then takes over where the other one left off. In the configuration of active/active the whole group of servers can be active and be backup servers to each other. Each server can take on the role of the others in this type of cluster configuration.

No matter the type of web hosting you choose, you should be sure that the web hosting company you choose clearly defines every aspect of their services and the services that are available to you and your company specifically. You should be very careful in your selection of a cluster hosting company. With cluster hosting there is the need to ensure that the web hosting company can provide you with an adequate number of cluster servers to handle the level of traffic your web site will experience. The success or failure of your company infrastructure depends on your choice in a web host.

The main reason for choosing cluster web hosting is be sure that there is a redundancy available in the computer network. This ensures that the network is always available and will not fail. In turn the company's website is always accessible and navigable.

How To Build Your Own Server

The measurement of a server is done in a unit called U, where 1U is equal to 1.75 inches. First of all you have to choose an operating system that you want to use while making server.

The Operating System Of The Server

Here i am taking a operating system (OS) from Microsoft and it is Windows 2000. It is not a server OS. It is not secure, and does not support .NET, but is still quite popular. The operating system can also be Windows Home Server, which is compatible with Windows XP and Vista clients. It is user-friendly, and has the Windows Home Server Console to administer or manage server remotely. The operating system can also be Windows 2003 Server, which supports .NET and can act as a domain controller, which means it plays a role in the logon process. Linux and FreeBSD are secure operating systems, but are very difficult to use.

You need to install Windows 2000 from the CD. To do so, you need to change the BIOS, so that you can boot from CD-ROM. Create a partition and format it with NTFS. You also need to configure the TCP/IP settings. Next, you need to go to Windows Update and install all the necessary patches to fix bugs.

Building an FTP Server

To build an FTP server, you need to download FileZilla Server, which is available in SourceForge. You need to add a new user and give him a password. You need to share the folders, which the user is able to access. You also need to give permissions, such as read (to download), write (to upload) and delete. If you want to set up a public FTP server, create a new user named 'Anonymous' and uncheck the password box. You can create a group, for a collection of users, who have the same permissions on a particular folder. You can access the FTP server by using the following URL: ftp://user:password@host:port. The host is your IP address, and the port is 21.

Instead of AppServ, you can use WampServer, which is also a combination of open-source applications in one package. The WampServer can start automatically when Windows starts, or you can manually start and stop the server everytime. The document root in WampServer is the 'www' directory. WampServer now supports PHP 5, but you can also use an add-on to support PHP 4. The normal user in MySQL is the root account, and the default password is blank. You can use the MySQL command-line tool, which brings up the console.

Instead of FileZilla, you can use the CrossFTP server. So, now that you have learned how to build a server, you can go ahead and make a personal home page or a front page for your business.

HP offers big business server solutions

Hewlett Packard (HP) has created a new range of "skinless" data centre servers which can be easily mounted in sever racks or server cabinets.

The company's HP ExSO portfolio is squarely aimed at large companies that require a lot of processing power concentrated in a small space.

According to HP, the new lightweight servers, which use simple mounting rails, give businesses the chance to reduce both shipping costs and expenditure on facility space.

"Customers with extreme scale out requirements like hosting companies or companies with high performance computing needs want to achieve greatest economy of scale," said Christian Keller, vice-president of industry standard servers at HP.

The company also claims that energy savings can be made because the devices have consolidated power and cooling infrastructure, which includes a unique air flow design.

HP states they require 28 per cent less power than traditional rack-mounted servers.

Meanwhile, HP has started supplying AMD's low-power Neo processors, which are dual-core and run at 1.6GHz.ADNFCR-1186-ID-19215098-ADNFCR

Apple iPhone OS 3.0 activations crash iTunes server

The mad grab for the newest version of Apple's iPhone won't begin in earnest until the iPhone 3G S is released on Friday. But a flood of current iPhone users looking to download the newest operating system, iPhone OS 3.0, crashed the activation server at the iTunes store on Wednesday.

Apple simultaneously released patches for 46 security vulnerabilities in the OS 3.0 which, if left unpatched, could allow hackers to execute malicious code through maliciously crafted images or PDF files.

After the operating system became available for download on the iTunes online store, many users reported being able to successfully download the upgrade, but were unable to activate the OS on their phones.

Disgruntled users received an error message that the iPhone activation server was temporarily unavailable.

The update is available for free for owners of the original iPhone and iPhone 3G, but iPod Touch owners have to pay $9.95 for the update. However, security experts warned that Touch users should get the upgrade to fix security holes in its operating system that were patched yesterday.
