很多库迁到Oracle 11.2.0.2后都遇到了问题。
现在正在跟的两个Oracle 11.2.0.2上的问题:
1.ORA-00600: internal error code, arguments: [ktecgsc:kcbz_objdchk], [0], [0], [1],
2.这个更扯,遇到几次了。想要enable block change tracking就会hang住。
SQL> select SID from v$mystat where rownum SID
----------
321
SQL> alter database enable block change tracking using file'/prod/dba/oracle/jporp/admin/ctf/block_change.ctf' reuse;
----Hang在这里
此时另外开一个session去看:
SQL> select SID,program,event,blocking_INSTANCE,BLOCKING_SESSION from v$session where sid=321 or BLOCKING_SESSION=321 or sid=610;
SID PROGRAM EVENT BLOCKING_INSTANCE BLOCKING_SESSION
---------- -------------------- -------------------- ----------------- ----------------
321 sqlplus@xxxx DFS lock handle 1 610
350 oracle@xxxx(CTWR). enq: CT - state chan ge gate 2 1 321
610 oracle@xxxx(CKPT). rdbms ipc reply 1 350
这个执行enable BCT的session 321,激活了CTWR进程350,结果321,350,再通过610 CKPT进程生了cycle。就hang 在那了。

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.
