I have no patience in writing things in my own space. Lazy people always have a way to pull it and transfer it to the monkey's blog. (How come there are some parasites )~ He prefers to harass monkey pulling, especially when he is busy, mainly to see
original file, it will only occupy a very small amount of disk space.-F: First delete files with dist file name when linking-D: Allows system managers to hard link their own directories-I: Ask before deleting files with the same file name as Dist-N: Dist is considered a general file when soft links are made-S: Soft link (symbolic link)-V: Displays the file name before the link-B: Backup files that will be overwritten or deleted when the link is made-S SUFFIX: Add the backup file to the end of t
For Example:
1. Create a connection to a file
[Root@a ~]# ln-s/home/kk/ss.sh ~ #如果不写目标地址, that is, in the current directory built link
[Root@a ~]# ls
Centos-base.repo.oldboy anaconda-ks.cfg install.log install.log.syslog ss.sh This command indicates that a link to the source file with the same name is created in the home directory to/home/kk/ss.sh Symbolic connection

Another example of "12c more consumption than 10g index back-table" case, colleagues in 12c run the buffer get is very high, but in 10g run a low buffer. Doubt whether the 12c optimizer has a problem.
This 10g environment and 12c environment, the amount of data is roughly the same, but there are very few differences, but this is a very small part of the difference, resulting in the NOT EXISTS subquery return different values, and then the outer query has a different impact.

// 2004-9-18Summary of internal classes:
1. the nesting of internal classes can be understood as the link between classes. When constructing an internal class (non-static) instance, the instance of the outer class will be directlyAs a parameter is passed into the constructor, And the instance of the outer class is also constructed using its instance of the outer class, so it is a chain-like relationship, the internal class can use allThe instance of the outer class, and the outer class cannot us
