我们在操作Oracle的时候,如果出现Oracle无法正常启动或停止,或者Oracle的导入导出命令执行错误,
通常是由于Oracle的实例下的表空间出现了问题造成的。
以下解决办法,摘自网络,适用于各种表空间文件出现问题的状况:
ora-01033:oracle initialization or shutdown in progress,经过分析研究终于解决了
一、首先:问题的产生原因,出现这个错误是因为我将oracle\oradata\oradb下的一个文件误删除掉后出现的。
二、现象:SQL*Plus无法连接,显示以下错误: ORA-01033: ORACLE initialization or shutdown in progress ,Enterprise Manager Console中也是同样的错误。
三、分析:应该是Oracle在启动后,用户登录时是要将方案中原有配置信息装载进入,,装载过程中遇到原有文件指定的位置上没有找到,所以就报出错误。
四、解决过程:
1、先在windows下运行cmd,进入DOS环境。
2、以DBA用户登录,具体命令是
sqlplus /NOLOG
SQL>connect sys/change_on_install as sysdba
提示:已成功
SQL>shutdown normal
提示:数据库已经关闭
已经卸载数据库
ORACLE 例程已经关闭
SQL>startup mount
提示:ORACLE例程已经启动
Total System Global Area 118255568 bytes
Fixed Size 282576 bytes
Variable Size 82886080 bytes
Database Buffers 33554432 bytes
Redo Buffers 532480 bytes
数据库装载完毕
SQL>alter database open;
提示:
第 1 行出现错误:
ORA-01157: 无法标识/锁定数据文件 19 - 请参阅 DBWR 跟踪文件
ORA-01110: 数据文件 19: ''''C:\oracle\oradata\oradb\FYGL.ORA''
这个提示文件部分根据每个人不同情况有点差别。
继续输入
SQL>alter database datafile 19 offline drop;
提示:数据库已更改。
循环使用最后两步,直到alter database open;后不再提示错误,出现“数据库已更改”。
然后接着输入即可
SQL>shutdown normal
提示:数据库已经关闭
已经卸载数据库
ORACLE 例程已经关闭
SQL>startup
提示:ORACLE例程已经启动
Total System Global Area 118255568 bytes
Fixed Size 282576 bytes
Variable Size 82886080 bytes
Database Buffers 33554432 bytes
Redo Buffers 532480 bytes
数据库装载完毕
就可以解决了。
5、最后说一下,第一条提到的隐患,因为创建了新的库,ORACLE_SID也就发生了变化,在用户登录的时候会有ORA-12560错误,解决这个问题是将系统注册表中的HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0\ORACLE_SID
键值修改成之前那个SID就可以了,用户也能就能正常登录了。

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
