Oracle 11g下UTL_TCP包居然用不通了调研
今天切换到Oracle11g下后,接着使用UTL_TCP与服务程序进行数据交互时,居然报出个ACL访问控制的问题,幸亏以前还有过些网络的基础
今天切换到Oracle11g下后,接着使用UTL_TCP与服务程序进行数据交互时,居然报出个ACL访问控制的问题,幸亏以前还有过些网络的基础,还知道ACL是个什么东西,,
而在Oracle11g下为了加强网络访问的安全性,对ACL进行了一个软的实现。下面就如何突破ACL这一层,进行了Oracle有关DBMS_NETWORK_ACL_ADMIN进行调研,下面是一些总结:
--ACL使用调研
关于让DBCoffer有关执行权限参考如下:
--用来获取主机IP或主机名
BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => 'coffer_acl_file.xml',
description => 'A test of the ACL functionality',
--参数为:一个用户或者是一个角色
principal => 'COFFER',
is_grant => TRUE,
privilege => 'resolve'
--start_date => SYSTIMESTAMP,
--end_date => NULL
);
COMMIT;
END;
/
--让用户能够访问外网的相关端口与IP
BEGIN
DBMS_NETWORK_ACL_ADMIN.add_privilege (
acl => 'coffer_acl_file.xml',
--参数为:一个用户或者是一个角色
principal => 'COFFER',
is_grant => TRUE,
privilege => 'connect'
--position => NULL,
--start_date => NULL,
--end_date => NULL
);
COMMIT;
END;
/
--对这个访问控制列表指定一条规则
BEGIN
DBMS_NETWORK_ACL_ADMIN.assign_acl (
acl => 'coffer_acl_file.xml',
host => '*');
COMMIT;
END;
/
--当升级一个DBCoffer用户时需要执行
BEGIN
DBMS_NETWORK_ACL_ADMIN.add_privilege (
acl => 'coffer_acl_file.xml',
--参数为:一个用户或者是一个角色
principal => 'TEST',
is_grant => TRUE,
privilege => 'resolve'
--position => NULL,
--start_date => NULL,
--end_date => NULL
);
COMMIT;
END;
/
BEGIN
DBMS_NETWORK_ACL_ADMIN.add_privilege (
acl => 'coffer_acl_file.xml',
--参数为:一个用户或者是一个角色
principal => 'TEST',
is_grant => TRUE,
privilege => 'connect'
--position => NULL,
--start_date => NULL,
--end_date => NULL
);
COMMIT;
END;
/
--当撤销一个DBCoffer用户时,需要执行
BEGIN
DBMS_NETWORK_ACL_ADMIN.delete_privilege (
acl => 'coffer_acl_file.xml',
--参数为:一个用户或者是一个角色
principal => 'TEST',
is_grant => TRUE,
privilege => 'resolve');
COMMIT;
END;
/
BEGIN
DBMS_NETWORK_ACL_ADMIN.delete_privilege (
acl => 'coffer_acl_file.xml',
--参数为:一个用户或者是一个角色
principal => 'TEST',
is_grant => TRUE,
privilege => 'connect');
COMMIT;
END;
--删除一个访问控制列表
BEGIN
DBMS_NETWORK_ACL_ADMIN.drop_acl (
acl => 'coffer_acl_file.xml');
COMMIT;
END;
/

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 article discusses using MySQL's ALTER TABLE statement to modify tables, including adding/dropping columns, renaming tables/columns, and changing column data types.

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.

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.
