It can boast improved scalability for business applications that enables to support more customer databases

and more simultaneous users on each server. Besides a 64-bit kernel can access more system resources, such

as memory allocation per user. A 64-bit processor can handle over 4 billion times more memory addresses than

a 32-bit processor. With these resources, even a very large database can be cached in memory.

Although many business applications run without problems on 32-bit systems, others have grown so complex

that they use up the 4 GB memory limitation of a 32-bit address space. With this large amount of data, fewer

memory resources are available to meet memory needs. On a 64-bit server, most queries are able to perform in

the buffers available to the database.

Some 32-bit applications make the transition to the 64-bit environment seamlessly others do not. For instance,

system-level utilities and programs that provide direct hardware access are likely to fail. Our program offers a

full-fledged support of the 64-bit architecture providing fault-tolerant work for such system dependent modules

as Hot Processing.

COPY OPERATIONS

Hard drive duplication nowadays is becoming highly popular among PC users. That is due to some definite

advantages it can offer. First of all, many people clone hard disks just to back up data for security reasons. The

present day copy utilities enable to successfully transfer all on-disk information including standard bootstrap

code and other system service structures, thus maintaining the operating system’s working capability. In case

of a system malfunction, the user can get the system back on track in minutes. No additional configuration is

required, what is very convenient.

The second possible application is the upgrade of a hard disk to a new one. The capacity of a modern hard

drive doubles every two years, thus opening up new possibilities for software developers. As a result programs

become more complicated and require considerable amount of free space. One day the user realizes that

there is no more free space left on the hard disk and the only way out is to upgrade. Usually that means that

besides purchasing a new hard disk, the user is to face a large re-installation procedure spanning several days

of tedious work. But all of this can be avoided just by copying the contents of the old hard disk to a new one

proportionally resizing the partitions.

And the last but not least is the copying of hard disks for cloning purposes. It may be of great use when setting

up similar computers. There is no need for a system administrator to install an operating system from scratch on

every one of them. It is enough just to configure one and then clone it to the others.

DRIVE PARTITIONING

As you probably know a hard drive is to be split into one or more partitions, since it cannot hold data until it is

carved up and space is set aside for an operating system. Until recently most PCs used to have just one

partition, which filled the entire hard disk and contained an OS. The situation has changed however, thanks to

new cost-effective high capacity hard drives, thus opening up numerous possibilities for PC users, such as

editing video, archiving music, backing up CD images, etc. Huge increase in space is great, but it poses a

number of problems, most important of which are effective data organization and speed.

Large drives are always going to take longer to search than smaller volumes, and an operating system is going

to have its work cut out both finding and organizing files. It is for this reason that many people decide to invest

in multiple hard drives, but there is an easy solution – drive partitioning. Partitioning lets you divide a single

physical drive into a number of logical drives, each of which servers as a container with its own drive letter and

volume label, thus enabling the operating system to process data more efficiently. Besides partitioning makes it

possible to organize data so that it is easy to find and manage. You can set aside, for instance, 40 GB of a 160
