What to do if Linux oracle data is garbled?
#Linux oracle Chinese garbled problem solution
The root cause of the garbled problem is characters Set modification
1. Check the default language of linux
2. Check the client’s language encoding settings
Configuration in the configuration file: cat ~/.bash_profile
Pay attention to modify the configuration information:
export PATH export ORACLE_HOME=/usr/lib/oracle/11.2/client64/ export LD_LIBRARY_PATH=:$ORACLE_HOME/lib:/usr/local/lib:$LD_LIBRARY_PATH:. export TNS_ADMIN=$ORACLE_HOME export PATH=$PATH:$ORACLE_HOME/bin: export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
After configuring, check whether the configuration is successful, sql statement: select userenv('language') from dual
3. Check the encoding used by the database: modify the default language of the linux oracle database
linux The default language for installing oracle is:
AMERICAN_AMERICA.WE8MSWIN1252
The Chinese display bit in this language is garbled.
After logging in to the Linux system through oracle, perform the following operations:
Modification method (taking changing to UTF8 as an example)
Log in to sqlplus with system DBA authority
$ sqlplus / as sysdba; select userenv('language') from dual;
For example: AMERICAN_AMERICA.WE8MSWIN1252
Modification:
SQL> shutdown immediate; SQL> startup mount; SQL> alter system enable restricted session; SQL> alter system set job_queue_processes=0; SQL> alter database open; SQL> alter database character set internal_use AL32UTF8; 或者 ALTER DATABASE character set INTERNAL_USE ZHS16GBK; SQL> shutdown immediate; SQL> startup SQL>alter system disable restricted session;
4. After modification, errors may occur in the original data in the database, and the table needs to be deleted and the data re-imported. . . . . . . .

Maintenance mode is a special operating level entered in Linux systems through single-user mode or rescue mode, and is used for system maintenance and repair. 1. Enter maintenance mode and use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can check and repair the file system and use the command "fsck/dev/sda1". 3. Advanced usage includes resetting the root user password, mounting the file system in read and write mode and editing the password file.

Maintenance mode is used for system maintenance and repair, allowing administrators to work in a simplified environment. 1. System Repair: Repair corrupt file system and boot loader. 2. Password reset: reset the root user password. 3. Package management: Install, update or delete software packages. By modifying the GRUB configuration or entering maintenance mode with specific keys, you can safely exit after performing maintenance tasks.

Linux network configuration can be completed through the following steps: 1. Configure the network interface, use the ip command to temporarily set or edit the configuration file persistence settings. 2. Set up a static IP, suitable for devices that require a fixed IP. 3. Manage the firewall and use the iptables or firewalld tools to control network traffic.

Maintenance mode plays a key role in Linux system management, helping to repair, upgrade and configuration changes. 1. Enter maintenance mode. You can select it through the GRUB menu or use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can perform file system repair and system update operations. 3. Advanced usage includes tasks such as resetting the root password. 4. Common errors such as not being able to enter maintenance mode or mount the file system, can be fixed by checking the GRUB configuration and using the fsck command.

The timing and reasons for using Linux maintenance mode: 1) When the system starts up, 2) When performing major system updates or upgrades, 3) When performing file system maintenance. Maintenance mode provides a safe and controlled environment, ensuring operational safety and efficiency, reducing impact on users, and enhancing system security.

Indispensable commands in Linux include: 1.ls: list directory contents; 2.cd: change working directory; 3.mkdir: create a new directory; 4.rm: delete file or directory; 5.cp: copy file or directory; 6.mv: move or rename file or directory. These commands help users manage files and systems efficiently by interacting with the kernel.

In Linux, file and directory management uses ls, cd, mkdir, rm, cp, mv commands, and permission management uses chmod, chown, and chgrp commands. 1. File and directory management commands such as ls-l list detailed information, mkdir-p recursively create directories. 2. Permission management commands such as chmod755file set file permissions, chownuserfile changes file owner, and chgrpgroupfile changes file group. These commands are based on file system structure and user and group systems, and operate and control through system calls and metadata.
