1. What is LVMLVM is a logical volume management tool that has two versions, LVM1 and LVM2. Native support in 2.4 kernal and 2.6kernal respectively.LVM provides management capabilities for higher logical levels of disk partitioning. The storage volumes can be re-partitioned and moved through LVM.LVM can name a logical volume custom named development, sales, etc., instead of "SDA" "SDB"2. A case description of the benefits of LVM: Joe's PCAs an Example:joe buys a PC with an 8.4 Gigabyte disk on i

Recently began to learn MONGO in the window installation has mastered, the operation is not difficult, the use of the work or the use of Linux in more. However, refer to some documentation after the installation is complete. Found a header error at startup MONGO
Finally, the problem is resolved by re-setting the path
Workaround: Enter the following command
[Root@localhost mongodb]#./bin/mongod-dbpath=/data/db
The interface will then appear:
[Root@localhost mongodb]#./bin/mongod-dbpath=/data/db
1. hide files or folders
If you don't want some folders or files to be seen by others, you can hide them! The following is the specific method of action.
Step 1: In the My Computer window, right-click the file or folder and choose Properties from the pop-up shortcut menu (see Figure 1, left) to open the File Properties dialog box.
Step 2: Check the "Hide" checkbox, and then click OK, as shown in Figure 1 right.
> Read only: When a file or folder is set to this property, it can only be opened

Mobile device Management (MDM) and OMA (OTA) DM Protocol Wizard (i)--from WiMAXFirst, why mobile device Management (MDM) is requiredMobile devices, such as mobile phones, have become very important communication tools, and the number of effective mobile users is growing every day, the complexity of mobile devices and the complexity of mobile data applications and services are rising. These trends have created significant management challenges for operators, as well as a lot of opportunities. Dat

Partitioned TableScalability is an important aspect of a database management system that provides table partitioning capabilities in terms of scalability in SQL Server 2005.In fact, for the relational database products, the table, database and server data partitioning to provide large amount of data support is not new, but SQL Server 2005 provides a novel architecture capabilities for the file groups in the database to table partitioning. A horizontal partition divides a table into severa
