Oracle 11g透明网关连接sybase数据库
之前已经整理过两个文档是关于oracle透明网关连接mysql数据库和sqlserver数据库的,本来以为不会再通过透明网关连接其他的数据库
前言:之前已经整理过两个文档是关于Oracle透明网关连接mysql数据库和sqlserver数据库的,本来以为不会再通过透明网关连接其他的数据库了,但是居然又碰到了,就是oracle通过透明网关连接sybase数据库,再次不厌其烦的整理成了文档;
注:里面整理了透明网关的搭建、连接sqlserver数据库、mysql数据库的方法,由于时间紧张请各位在博客里面搜索下;
正文:配置透明网关连接sybase数据库的方法其实和连接sqlserver的方法,几乎是一模一样的。(有网友说明需要安装sybase的客户端驱动,但是经过验证是不用的)
二、详细的操作截图如下:
按照以上步骤操作即可;
三、透明网关的配置
3.1配置透明网关的参数文件
进入目录:$ORACLE_HOME/dg4sybs/admin/
根据参数文件initdg4sybs.ora,创建一个参数文件initecc.ora(参数文件名为initsid.ora)
# This is a customized agent init file that contains the HS parameters
# that are needed for the Database Gateway for Sybase
#
# HS init parameters
#
HS_FDS_CONNECT_INFO=192.168.0.124:4901/ECC(修改该栏即可)
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
3.2 修改数据库的监听配置
注:只在SID_LIST下面增加SID_DESC:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC=
(SID_NAME=ECC)
(ORACLE_HOME=d:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM=dg4sybs)
)
)
请注意:
SID_NAME要跟上面的参数文件名称相对应
ORACLE_HOME 目录跟实际的安装目录相符
PROGRAM 为dg4sybs
配置好监听文件后,重启下lisnrctl
3.3 增减tnsnames文件的配置
ECC =(注:可设置为任意名)
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST= localhost)(PORT=1521))
(CONNECT_DATA=(SID=ECC))
(HS=OK)
)
请注意:
SID的名字为监听文件配置的名字;
配置完成,可以运行tnsping ECC
四、配置dblink
SQL> CREATE PUBLIC DATABASE LINK ECC_LINK CONNECT TO "username" IDENTIFIED BY "password" USING 'ECC';
ECC_LINK名字可以根据要求自己定;
'ECC'为tnsnames文件配置的名称;
配置完成运行:select * from dual@ECC_LINK; 有返回值说明配置成功;
提示: sybase 数据库是区分大小写的,,因此许多表名、字段如果含有小写内容,需要用双引号扩住。
实际上 oracle 也是可以区分大小写的,但平时只要不用双引号,oracle 会自动转化为大写。
总结:透明网关连接sybase的设置跟sqlserver的配置几乎是一样的,按照这个操作一般是没有问题的,但是整个过程设计的名称建议有一个内部的规范,后面再使用的过程中就会发现这个规范带来的管理上的好处;

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.

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.

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.

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.
