将Oracle的数据初始化到mysql,使用oracle to mysl 工具将oracle的数据类型映射成mysql的数据类型,并作相应的修改,使mysql可容纳oracle的字段长度,本文执行初始数据,并没有做复制,只是导数据过去,而且源端的oracle数据库是静止的,如果非静止就需要配置抽取进程和应用进程
1.编辑mgr参数
source
edit param mgr

2.启动mgr
source
start mgr
info all
target
start mgr
info all
3.编辑初始化进程
初始化的进程不需要启动
source
edit param extinit
SOURCEISTABLE
setenv (NLS_LANG="AMERICAN_AMERICA.AL32UTF8")
userid goldengate, password goldengate
RMTHOST 10.58.8.26,MGRPORT 7819
RMTFILE /data/goldengate/rmtfile 5000,MEGABYTES 1024
scott.*;
target
edit param repinit
SPECIALRUN
END RUNTIME
setenv (NLS_LANG = AMERICAN_AMERICA.AL32UTF8)
DBOPTIONS HOST 127.0.0.1, CONNECTIONPORT 3306
TARGETDB testdb,userid root,password root_password
EXTFILE /data/goldengate/rmtfile
assumetargetdefs
MAP scott.*, TARGET testdb.*;
---此处可能出现问题,可以先使用dblogin 测试用户是否可以登录mysql数据库,可能会报/tmp/scok的错误,是由于手工编译安装mysql,,tmp下没有这个文件,在tmp创文件并ln 到真正的安装目录的sock文件
4.启动初始化
source
cd /data/goldengate/
/data/goldengate/extract paramfile dirprm/extinit.prm reportfile dirrpt/extinit.rpt
target
cd /data/goldengate/
/data/goldengate/replicat paramfile dirprm/repinit.prm reportfile dirrpt/repinit.rpt

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.

Using mysqldump for logical backup and MySQLEnterpriseBackup for hot backup are effective ways to back up MySQL databases. 1. Use mysqldump to back up the database: mysqldump-uroot-pmydatabase>mydatabase_backup.sql. 2. Use MySQLEnterpriseBackup for hot backup: mysqlbackup--user=root-password=password--backup-dir=/path/to/backupbackup. When recovering, use the corresponding life

The main reasons for slow MySQL query include missing or improper use of indexes, query complexity, excessive data volume and insufficient hardware resources. Optimization suggestions include: 1. Create appropriate indexes; 2. Optimize query statements; 3. Use table partitioning technology; 4. Appropriately upgrade hardware.

MySQL view is a virtual table based on SQL query results and does not store data. 1) Views simplify complex queries, 2) Enhance data security, and 3) Maintain data consistency. Views are stored queries in databases that can be used like tables, but data is generated dynamically.
