We can use its read/write operations as a means to communicate with the kernel object. In other words

The sys password of the Oracle 10g ASM instance sometimes needs to be modified. The modification method is to directly modify the password file of the ASM instance, which is different from that of the user in the database instance. We cannot use the alter user command to modify the sys user password of the ASM database. The sys password of ASM can only be provide

Config. sys is an important file in the dossystem. Its Configuration directly affects the usage and efficiency of the system. If improperly configured, many programs may fail to run normally. Therefore, it is necessary and important to correctly configure the config. SYS file. The following describes the commands in config. sys and their configuration methods.

In general, the sys. stdout function is similar to the file output function fprintf in C ++. Next, let's take a look at the Code: >>> Import sys >>> temp = sys. stdout >>> sys. stdout = open ('e: \ pythonCode \ 1.txt ', 'w') # Note: dual \> print 1, 2, 3. the preceding three numbers are added to segment 1.txt>

In the Linux distribution, there is a/proc/directory, some also called it the proc file system. In this directory, there are special files that can be used not only to reflect the current state of the kernel and to view hardware information, but also to allow users to modify the contents of the kernel to adjust the current working state of the kernels, such as files under the/proc/sys/subdirectory. Unlike other directories in the/proc/directory, file

One, the most important difference: the importance of storing data is different"SYS" the base tables and views of all Oracle data dictionaries are stored in the SYS user, which is critical to the operation of Oracle, maintained by the database itself, and cannot be changed manually by any user.
