在win7 64bit上装 Oracle11g第2版-11.2.0.1.0-win32,oralce成功安装,但在连plsql老是报:ORA-12514 TNS:监听程序当前无法识别连接描述符中请求的服务
解决过程:
1. 找到listener.ora监听文件,具体位置:D:\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
2. 在lisener.ora文件中找到
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\oracle\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
将下面的一段内容copy进去,并适当修改。(红字部分为你的SID,其中GLOBAL_DBNAME为全局数据库名,可以与SID不同)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME =D:\oracle\product\11.2.0\dbhome_1 )
(SID_NAME = orcl)
)
3. 保存listener.ora文件,关闭并重新启动监听程序,问题解决!

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
