As soon as this incident came out, Lin Man was also called to his office by Secretary Luo, and he criticized it fiercely, although he raised enough funds for the activities of the Association for Science and Technology, but his behavior was inappropriate, and warned him not to engage in these crooked ways for the sake of work.

Lin Man slipped out, only to find that he was busy until now, hungry and unbearable, lunch was delayed by Prince Jin, and dinner was about to be over because of criticism. Do you want to continue to invite Zhang Yan to dinner? Lin Man promised to invite guests for a week, starting last Thursday, and today is already Friday, and it has been more than seven days. As soon as Lin Man touched the meal ticket in his pocket, he decided not to invite Zhang Yan to dinner, because the meal ticket in his pocket was not even enough for his own dinner.

"Who are you looking for for dinner? Let's find Zhao Bin. Lin Man was thinking about Zhao Bin in his heart, and he heard Zhao Bin's voice behind him.

"Lin Man, why are you here? Come with us and fill the façade. ”

Lin Man turned his head and saw Tong Tong, deputy secretary of the Youth League Committee of the school next to him, walking towards a van not far away with a group of people. Zhao Bin pulled Lin Man to keep up with the team.

What is going on? Lin Man didn't understand what was going on. Secretary Tong is known to him, he is a computer student, but he is more interested in doing business. At present, he founded a Qirui Technology Co., Ltd. in the name of the Youth League Committee, and the office is located on the third floor of the Youth League Committee. In just over a year, it is said that he has earned a lot. Zhao Bin has a position in the company and has a salary, so his life is much better than Lin Man's. Which one is this singing tonight?

Zhao Bin explained to Lin Man in a low voice in the car. It turned out that Qirui had recently done business with CCB and was jointly developing a phone banking project. Tonight, some of CCB's equipment will be moved into the new computer room, and Qirui, as a high-tech company relying on universities, has taken the initiative to ask for technical support to help deal with unexpected situations.

"Actually, what's the matter? There are not many people who are going tonight who really understand technology. The brother in the front row is said to be a programming master, and the others are probably similar to me. ”

"Then what are you pulling me for?" Lin Man didn't think it was a good errand, and his stomach was rumbling with hunger, and he really didn't want to wade into troubled waters.

"Stupid. You have always been unfamiliar with Secretary Tong, take this opportunity to get in touch more, and it will be convenient to promote you in the Association for Science and Technology in the future. ”

But equipment relocation is really not a good thing. Before Lin Man studied for a doctorate in his previous life, he worked as an operation and maintenance engineer for several years, specializing in maintaining Unix servers of IBM and HP.

For a unit like a bank, the equipment must not be moved during the daytime business hours, it must be relocated at night, and the system must be re-operated before dawn, otherwise it will affect the normal business of the next day, which is a major accident.

Of course, this kind of thing can be hid as far as it can, how can it move forward? It seems that Secretary Tong is in a hurry to complete the business, and he can't take care of the risks.

Sure enough, the relocation site was hectic. Most of those expensive minicomputer servers exist in the form of one-person tall racks, and at least two migrant workers move one. Some were too heavy, so two bamboo poles were stretched directly in the rack, and four migrant workers carried them together. Seeing Lin Manzhi frowned. These people don't know how to lift lightly, and if they were told that there were millions on that device, I don't know if they would lift it like this.

Zhao Bin was busy for a while, tired, and sat on a low server to rest. Lin Man looked at it, it was a black IBM server, and joked with Zhao Bin: "You know, your current sitting posture is the most stylish, it's cool." ”

Zhao Bin didn't understand what he meant. Lin Man pointed to the server under his ass and said, "Your stool is worth at least 400,000, don't you think it's cool?"

Zhao Bin immediately jumped up. 400,000 in this era is worth the old nose money. In the past few years, a 10,000-yuan household was advertised like a millionaire.

Sure enough, this chaotic relocation really went wrong. Secretary Tong looked anxious, and a young teacher next to him who came with everyone seemed to be saying something helplessly, that Senior Brother Tang was just a programming master, and it seemed that there was nothing he could do.

Lin Man sighed and stepped forward, hoping that he could help. I am not very familiar with the equipment and systems of this era. The helpless teacher, surnamed Qian, told Lin Man that after the people from CCB started the database just now, they deleted some files, and then the database could not be started. Luckily, it's not a hardware failure.

"I'll give it a try. Lin Man said to Secretary Tong.

Secretary Tong looked at Lin Man suspiciously, and then motioned for Lin Man to step forward, at this time, those who dare to come forward should have two brushes, and all the dead horses should be live horse doctors.

Lin Man knocked two commands in front of the terminal, it was the Informix database, which was no longer popular in later generations, but fortunately he had learned a little by himself. Lin Man asked the young man from CCB who was operating just now: "Why did you delete the file just now?"

"The script has been running for a long time without results, and this has been happening for many days. I thought it was because there were too many logs in the past and it took up too many resources, so I wanted to delete some files, and it turned out ......"

Well, Lin Man understands a little. In the middle of the night, I was a little stressed and nervous, and there was a mistake. The child is still young, understandably so. This guy didn't think about it, in terms of age, he was a few years younger than that "child".

Lin Man quickly checked the running logs, found the script that reported the error, and began to manually restore some files. Unix doesn't have a recycle bin, and luckily it's just deleted some configuration scripts.

Seeing Lin Man confidently typing on the keyboard there, Secretary Tong's hanging heart relaxed, and he turned around and asked Zhao Bin: "Is he from the computer department, how many years have you been studying?"

Zhao Bin was only surprised, and didn't think much about it, so he said: "He is Lin Man, from the Department of Mechanics, like me, a freshman, the head of the Propaganda Department of the Association for Science and Technology, and he is very good at painting." ”

It turned out that he was Lin Man, and he had always heard this name recently. Secretary Tong's originally relieved heart picked up again, and he almost wanted to kick Zhao Bin. It's a small computer, and it definitely belongs to the elite class to play high-end things, not the PC and DOS operating system that students play, I didn't see the money I brought to the teacher, it was a master of playing small computers in the school. I'm really dizzy, how can I let him go up and try it, if there is a problem, it is all the responsibility of Qirui Company.

Lin Man was still recovering the file in an orderly manner. The most important thing to deal with this kind of failure is to keep a clear head and clear thinking, especially not to fully trust the customer's description. Sure enough, after several startup failures, Lin Man found a new problem, repaired the file, and tried to start the database again.

"It worked. The young man cried out excitedly, and let out a sigh of relief, great, if there was an accident, he would be miserable. At this time, he was young and did not think of putting the responsibility on others.

Everyone around them breathed a sigh of relief.

Director Zhou of the Information Department, who came to deal with the problem, also smiled, shook hands with Secretary Tong, expressed his gratitude, and then said: "Xiaobai, tell this young man about the problem you found earlier, and see if you can solve it." ”

The young man, who was called Xiaobai, repeated the problem of inconclusion for a long time after the script was executed.

Lin Man looked up at Secretary Tong, and waited for him to signal, at this moment, the leader must be highlighted, and the responsibility cannot be easily taken.

Secretary Tong asked, "Are you sure?"

"I'll do my best. Lin Man's face was full of confidence. I don't have other skills, but I still have this ability in the field I am familiar with.

Secretary Tong nodded. I hope he can solve the problem again, then the follow-up business will not be able to run.

Lin Man first used the Top command to check the parameters of the running performance, and the memory was only consumed by 20%, only one of the four CPUs was used at 99%, and the other three were sleeping.

Lin Man basically counted, a typical single-process task, unable to play the performance of multiple CPUs, ruined such a good machine. Lin Man began to check the scripts and found that they were all commands for database retrieval backups. Soon Lin Man found a suspicious line of code, which was a select statement to query the database, which was actually to query all the data of all fields in the entire database, and there was no index to improve query efficiency. It seems that the database management system itself has not dealt with the problem of parallel retrieval well. As long as the amount of data is large enough, this statement will need to be executed for several hours.

Lin Man asked Xiaobai: "Have you noticed that the system used to run very fast when it was first established, and then it became slower and slower, and it has to wait for a long time recently?"

Xiaobai nodded again and again: "Yes, yes, yes, that's right." ”

"Is your data getting more and more and growing fast?"

"That's right, it's at least 100 times more than it was at the beginning. Xiaobai already thinks that Lin Man is a "miracle doctor".

Lin Man pointed to the select statement and said, "Let the person who wrote the business processing script modify this sentence, and you can solve your trouble." Then Lin Man gave him a brief explanation of the technical reasons. As for how to modify it, it's not Lin Man's business.

Director Zhou is very satisfied, Qirui Company is really a master.

Secretary Tong is also very happy, the person Zhao Bin found today is good, very good.

Only Lin Man is not good, he is really hungry, even if he gives saliva. However, this is a special computer room, fireproof, anti-theft and waterproof, and only the discharge port for releasing carbon dioxide is seen, and there is not even a faucet.

Lin Man wanted to leave, but no one sent him. Director Zhou is even more unlikely to let them go, and the following cities are also completing the relocation of the computer room at the same time, and after the equipment is in place, the whole system will be tested online. Who knows what will happen next?

I have nothing to do but wait silently, I'm really hungry.

Teacher Qian and Senior Brother Tang came over to chat with Lin Man and introduced each other. Mr. Qian is very funny, he is the maintenance teacher of the school's computer room, named Qian Duoduo, he said that when he was a child, he was originally called Qian Duoduo, but when he grew up, he insisted on changing his name, but the money was really not much. Senior Brother Tang's name is Tang Pinrong, a computer researcher, and to Lin Man's surprise, his tutor is actually Professor Chen Cailiang, a big bull in the Department of Computer Science. This person has to be caught, and whether he can hug his thighs in the future depends on Senior Brother Tang. Lin Man was interested, and the three of them chatted enthusiastically, which matched the lively scene in the computer room very well.

Just when Lin Man thought that this night was about to pass happily, he was calling Master Lin to come over.

(This part may be on the more professional side, and I will try to avoid this in the future.)
