SYSTEM and UNDO tablespaces are usually placed on RAID 1 volumes.
Online redo logs are usually placed on RAID 0 volumes.
Control files are usually placed on RAID 0 + 1 volumes.
Data files are usually placed on RAID 5 volumes.

4. ASM architecture (mainly composed of an ASM instance and an ASM disk group)
1 To use ASM, you need to create an ASM instance for managing the ASM disk group.2 An ASM disk is composed of one or more ASM disks.3 An ASM disk can be an actual disk, a partition of a disk, or a logical volume managed by LVM, but must be an unformatted raw device.4The size of the ASM disk group is the tota
displays items on the toolbar at an equal distance within its width range. It is best to limit the number of items displayed on the toolbar so that users can easily click on the items they need. We recommend that you use 44x44 pixels in the click area of the user interface elements. Therefore, it is reasonable to provide you with the following five toolbar items. The example in Figure 6-9 shows a toolbar example with moderate spacing.

Specific Operation Method: Enter the CMOS setup according to the system prompt when starting the system (if it is award and other bios, a prompt will be prompted to press del to enter the cmossetup, if it is an Intel motherboard, usually press f2 to enter the CMOS setup), then select low formatted harddisk drive in the CMOS menu, and then perform the hard drive

Xwriterlib implements the HTML document generator internally. Therefore, xwriterlib can independently output HTML documents without relying on other components.
Document loading and saving
Xwriterlib supports multiple methods to load and save documents. Xwriterlib supports the RTF format internally. Therefore, you can call its interface to load and save documents in the RTF format. Developers can also use p

For me, the following things are very effective: I outline what I want to write the next morning. Just like writing a note. I found that writing it on paper is more effective than writing it on a computer.
Or, I will look at some programming/algorithm problems. Similarly, the framework is described on paper or written out. Surprisingly, you may find a solution in the morning! I wrote a

has the total number of data blocks it contains. This is always the sum of the number of allocated data blocks and the number of indirect data blocks. Fsck compares the total number of data blocks it calculates with the total number of data blocks in the file node to see if the two are consistent. If they are different, fsck will fix them. In addition, each file node contains a 32-bit length field, which indicates the description of the file size in bytes.3.7. Check the data associated with the

A process with the read permission can read messages from the queue. The message queue overcomes the disadvantages such as the small amount of information carried by the signal, the pipe can only be the
