引言:最近在论坛里经常会看到有朋友咨询Oracle GG 实施案例的帖子,诚然 GG 目前在各大论坛里的资料都不是很多 很全,尤其是真实实施案例就更凤毛麟角了,鉴于此我今天就为大家转一份朋友做过的GG实施给大家分享,本次分享的是“相同数据库之间的复制”,话不多说,赶紧上干货。
 
实验环境:oracle10g+RedHat4+goldengate

一、安装redhat4,安装步骤略

二、安装oracle10g安装步骤略

三、安装goldengate,注意要选对版本

1、源端安装配置

1.1安装goldengate

linux: mkdir /u01/oracle/ggate
cd /u01/oracle/ggate

通过ftp,将goldengate的zip软件上传到/u01/oracle/ggate

unzip解压,,将生成一个tar文件

tar -xvf *.tar

1.2配置.bash_profile


vi .bash_profile
添加:
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/u01/oracle/ggate
export GGATE_HOME=/u01/oracle/ggate

注意LD_LIBRARY_PATH,那一行,可以在原来安装oracle的基础上添加在后面便可

配置完,运行source ~./bash_profile

1.3创建goldengate目录

cd /u01/oracle/ggate

./ggsci(进入goldengate命令行界面)
Oracle GoldenGate Command Interpreter for Oracle
Version 11.1.1.0.0 Build 078
Linux, x86, 32bit (optimized), Oracle 10 on Jul 28 2010 13:24:18
Copyright (C) 1995, 2010, Oracle and/or its affiliates. All rights reserved


现在在goldengate命令行工作

create subdirs

1.4配置数据库归档模式,进入sql命令行(如果关闭,建议开启)

sqlplus "/as sysdba"

alter system set log_archive_format='%s_%t_%r.log' scope=spfile;

alter system set log_archive_dest_1='location=/u02/oracle/arc';

shutdown immediate;

startup mount;

alter database archivelog;

开启强制日志模式:alter database force logging;

alter database open;

这下可以看一下归档是否已经起来,archive log list

1.5开启minimal supplemental logging

--alter database add supplemental log data;这种设置是许多文档介绍的,但是对于非主键或唯一索引表的会有问题,在测试过程中,发觉update会报错,可能其它地方没搞好!

alter database add supplemental log data(primary key,unique) columns;这是我的配置!

1.6关闭回收站

alter system set recyclebin=off scope=spfile;

1.7配置复制的DDL支持

创建用户授权:

create user ggate identified by ggate default tablespace users temporary tablespace temp quota unlimited on users;

grant connect,resource,dba to ggate;

grant execute on utl_file to ggate;

grant restricted session to ggate;

@$GGATE_HOME/marker_setup.sql;

SCHEMA:GGATE

@$GGATE_HOME/ddl_setup.sql;

这里要看清楚,选择输入,否则会有问题!

@$GGATE_HOME/role_setup.sql;

授予角色权力:
grant GGS_GGSUSER_ROLE to ggate;
@$GGATE_HOME/ddl_enable.sql;

1.8创建源端用户(用于同步的用户)
create user sender identified by ggate default tablespace users temporary tablespace temp quota unlimited on users;
grant dba,connect,resource to ggate;
grant select on v_$session to ggate;

linux

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

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.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

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.

Can I install mysql on Windows 7 Can I install mysql on Windows 7 Apr 08, 2025 pm 03:21 PM

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.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

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: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

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.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

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.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

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.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

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.
