preceding checks, theoretically the CPU should be able to take the finger for execution. To better track the startup process and identify and analyze the symptoms and causes of startup failure in time, you need to initialize the serial port, seven-segment digital tube, or gpio/LED lamp in the BIOS as soon as possible, in addition, print the output of each important startup step in the bios, or click the LED light and display the agreed output in the 7-segment digital tube. Of course, if the sys
array before this installation. Therefore, the disk array configuration is not described in this document.

Redhat is newly installed for the server, and the server is dedicated to oracle.
(1) create a drive floppy disk based on the driver provided by IBM.
(2) Configure BMC

return, the maintenance engineer brought the latest CPU management board (CPU Management Control) firmware (firmware), then upgraded the CPU management plate firmware, the server returned to normal immediately.
Firmware upgrade method is, 1 use floppy disk to start the computer, and then insert firmware floppy disk and run the relevant file Cabrillo above; 2 The system refreshes the BMC (motherboard controller) and HSC (Hot-swappable backplane Contr
1. Create an account
First create an account:
Useraddxxx #xxx为用户名
passwd xxx
Then CD to the NIS environment directory, perform make, synchronize other node accounts
Cd/var/yp
Make
This is the account that is available for all compute nodes
Implement SSH without password login (if required):
Switch to XXX account:
Su xxx
ssh-keygen-t RSA #回车三次
Ssh-copy-id localhost #回车输入密码即可
Complete
2. If the management node freezes
Need to log in to BMC IP to

end date is 3, then subtract 3 days from the total days, if the end date is 6 or Sunday, subtract 6 or 7, and then add 1 or 2 at the end.
There is no difficulty in the algorithm, the core idea is to adjust this time period to 7 of integers, and then multiplied by 2, in minus or plus more and less than Saturday or Sunday, is the sum of Saturday and Sunday. The final calculation of the number of days, not recommended by date (z) to calculate, because the general will not be good, related to the
In fact, the enumeration is very simple, but did not learn well before, so do not know this thing, well, now combOverall, the first enumeration is a data type, and the data type and struct are a bit likeCan be divided into three levels1. Enumerating Data type definitionsFirst type: Enum enum name {Enumeration element 1,Enumeration Element 2,......,......}egEnum Week{sun,mon,tue,wed,thu,fri,sat};2. Definition of enumeration variablesThere are two main ways ofMethod One: Define an enumeration vari

Eomonth
Returns the number of series of the last day of the specified month before or after start-date. The eomonth function is used to calculate the number of time series of the last day of a specific month. It is used to calculate the expiration date of securities.
Eomonth (start_date, months)
Hour
Returns the hour of the time value. It is an integer between 0 (a.m.) and 23 (p.m.
Hour (serial_number)
Minute
Returns the m

Do we need to use statistics to summarize this?
In fact, it is not necessary. We have proposed a concept:ValidCodeQuantity.
Valid code volume = total code volume/total code time(Recommended unit: WorkDay)

change effect in IE, F5 refreshed, and did not see the effect. Hey, there was a cache problem! Close the browser and check the effect again. At this time, there is a kind of subconscious, that is, I re-opened the browser, certainly not a cache problem. Then I found a variety of problems, finally turned back, manually cleaned up the cache, run! It's a cache problem! This total subconscious is enough!

There are many problems with the process, such as design.

To solve the above problems, we need to design a business Time System for the system.

Networkdays
Returns the complete workday value between start-data and end-data. Workdays do not include weekends and specified holidays

Such as:Enum weekday workday,week_end;Workday and week_end are defined as enumeration variables, and their values can only be sum to one of the SAT . Such as:Workday = Mon;Week_end = sum;Equivalent toenum {Sum,mon,tue,wed,thu,fri,sat}
