第 1 行出现错误:
ORA-16014: 日志 1 的序列号 242 未归档, 没有可用的目的地
ORA-00312: 联机日志 1 线程 1:

db_recovery_file_dest string C:\oracle\product\10.2.0\db_1/

检查flash recovery area的使用情况:

ARCHIVELOG 25.06 0 35
BACKUPPIECE 67.69 0 4
IMAGECOPY 0 0 0
FLASHBACKLOG 0 0 0
已选择6行。
计算flash recovery area已经占用的空间:
SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;
SUM(PERCENT_SPACE_USED)*3/100
-----------------------------
3.012
可以看到,这里已经有3.012G使用了,这说明我们刚开始设置的db_recovery_file_dest_size=2G不足,导致online redo log无法归档,在这里,我们通过设置db_recovery_file_dest_size参数,增大了flash recovery area来解决这个问题:
alter system set db_recovery_file_dest_size=3G scope=both;
也可以在rman中通过删除flash recovery area中不必要的备份来释放flash recovery area空间来解决这个问题:
打开命令行
set oracle_sid=thrs
rman target dw/* as sysdba
delete archivelog all completed before 'sysdate-7';(指定删除7天前的归档日志)
或者
delete archivelog until time "sysdate - 7";

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
