51 There are many brothers and sisters to participate in the training, and the enthusiasm of everyone knows is really good, and there are self-funded training, more touched. Let me say that I learn AIX's passions and feelings, please refer to.
I didn't get exposed to AIX in 1998. I used to get Sun, first I feel that AIX is really simple, nothing is needed, everything is a menu, all the way to enter the car is OK. So I started working, I won't ask questions, online search information. I think the ability of online search materials is especially important. You ask someone else, or there is no time, and there are some things because of their initial school, often express unclear, and need many interactions, it is better to find it. If someone is really helping you, of course, it is very good, but the enthusiastic man who can encounter the old farmers will see his own creation.
Because there are books, there are nets, there are machines, there is practice, so I feel that I have learned very quickly, I think it can be, so I don't know how much I don't know, the order is not Cooked, concept is unclear. So again, practice. This stage is long, because I don't know what to learn, the information I can find online is also very beautiful. I have something everywhere, I can't find anything I want to find. In addition, at this time, it is often found that the book is written, or someone else is not in line with the reality. confused.
Especially there are some rare and quirky things, inexplicable problems, inexplicably good. Probably some old engineers said that luck is very important. I don't believe, because it is not logical, but the time is long, there is no way, I have to believe, so the family is driving in the direction of Austin (the original 6000 / AIX R & D center), the first fainted in the morning, morning and evening. (This paragraph is a joke, don't care seriously)
Nothing is not dead, there is always reason, but sometimes it is clear that it is clear, it is very difficult, it is difficult to see the cold, the sky is cold, the fish is hidden, I can't do it. . What do you want to know is too much, and there is a new upgrade (software, hardware) every ten days and a half, didn't wait for you to understand, upgrade, the problem is gone, I don't know whether it is bug or the wind is not good. The ground wire, crosstalk, and improper use), the previous analysis is white.
So, now develop a nature of the nature, the problem of the lightweight, is still not good, there is no change, and it will naturally be a few days a few months. I am gambling, I must not exceed 3 years!
Now what we said, what is the technology? During the study, there is no original. The people who definitely IEEE, RFC are certainly not me, almost not you, I just tell other people in what others record it. I have encountered a person who wrote the R6 Troubleshooting red book, asking the book how to have it, answer: Dong copy the West.
--------------------
The words retired, in order not to dispel the enthusiasm of everyone, to give you a boring, say a learning experience.
AIX is nothing more than a few things:
Logical volume management
Memory Management
CPC Processor Scheduling
TCPIP
Interface Management (Various Unimblered Interfaces, SCSI, FC, NetWork, TTY, ..)
User Management
Cluster management (high availability and high performance calculations)
Before learning, it is recommended to start from two aspects: one is the theoretical basis, all computer systems] are almost, regardless of hp / sun / alpha, even Windows, you want to make this thing, how do you design? This operating system. There is always a architecture model in the heart there. There is a certain relationship between each component.
The other is command and parameters and output interpretation. This is a skilled problem that uses commands to implement your requirements.
Keep in keeping these two points, when learning AIX, learn from these two aspects.
------------------------------
Next, get started.
Logical volume management is also stored, what is storage? That is, the space is stored in the data block, although there are many diversified storage types, but always let the operating system be regarded as a series of data block storage spaces. How to manage? It is the physical disk becomes a logic disk. The plurality of logical trays are combined into VG, VG is divided into large data blocks, and part of the data blocks are divided into LV, and the LV can be used directly (just called naked equipment), and can also Built the file system again. There is a file in the file system (the directory is also a special file, the index file), and there is a certain parameter between each level to another level. Of course there is also a command.
The same is true of other memory, CPU management, too much, can't write, look at it.
----------------------------------
Next, in-depth
This is the continuation of the entry, and the relevant commands have been found (do not try it on the production system!), The parameters research will be.
---------------------------------
Next, deeper
If you don't look back, you're easy to learn better, it is best to move the book of the university computer principle, look at the queue, interruption, scheduling, signal, lock, you will find AIX to achieve these things. The network protocol also knows that probably, transport theory, etc.
--------------------------------
Next, proficient
If you don't go to program, you can't be proficient. Your program is that, you are fine.
--------------------------------
Walk
Workers must be good, and must first make a tool. Information is very important, find the teacher to be material, online collection. In fact, there are a lot of people in AIX, and Google has a search, one piece.
--------------------------------
note:
Don't ask if you don't ask, really ask for an emotion, you can figure it out.
--------------------------------
Remarks:
When you learn almost the same, I want to learn it. I don't have any use. Many technologies I will not, but as long as I need it, I can master it within three days, I will be fine in a week. Finite strength, especially for some light, and learn too much.
Of course, the premise is that you have many things. Big capitalists will consider investment returns, if they are still 乞丐, I have to pick it up.
