完整oracle 流复制配置

 
基本环境搭配:

Sqlplus ‘/ as sysdba’

alter system set aq_tm_processes=2 scope=both; //不要设置成0或者10, 这样做可能禁用队列监测处理和影响流池内存利用率.

alter system set global_names=true scope=both;

alter system set job_queue_processes=10 scope=both; //建议的最低值为4,定义传播进程数.

alter system set parallel_max_servers=20 scope=both;//并行执行可用的最大进程数量

alter system set undo_retention=3600 scope=both;//数据提交后至少保留的秒数.
alter system set nls_date_format='YYYY-MM-DD HH24:MI:SS' scope=spfile;//时间格式
alter system set streams_pool_size=256M scope=spfile;//没有捕获进程无须配置此处
alter system set utl_file_dir='*' scope=spfile; //*代表可以操作任何目录

alter system set open_links=4 scope=spfile; //数据库连接数.DB_LINK

重启数据库

shutdown;

startup;

*将数据库置为归档模式:

sqlplus ‘/ as sysdba’

alter system set log_archive_dest_1='location=E:\oracle\product\10.2.0\archive\arch' scope=spfile; //归档日志路径

alter system set log_archive_start=TRUE scope=spfile;

alter system set log_archive_format='arch%t_%s_%r.arc’ scope=spfile;//设置归档模式固定参数
shutdown immediate;

startup mount;

alter database archivelog;

alter database open;

 

//alter system set log_archive_dest_state_2='enable' scope=both;

SQL> archive log list

 

创建主从环境stream管理用户:

创建主环境的Stream专用表空间

Connect / as sysdba

Create tablespace tbs_stream datafile 'E:\oracle\product\10.2.0\oradata\michael\tbs_stream01.dbf' size 100m autoextend on maxsize unlimited segment space management auto; //表空间大小视情况

Execute dbms_logmnr_d.set_tablespace ('tbs_stream');

 

创建Stream管理用户并授权

create user strmadmin identified by strmadmin default tablespace tbs_stream temporary tablespace temp;

grant connect,resource,dba,aq_administrator_role to strmadmin;

begin

dbms_streams_auth.grant_admin_privilege(

grantee => 'strmadmin',

grant_privileges => true);

end;

创建主数据库数据库链:

connect strmadmin/strmadmin

create public database link peter.landun connect to strmadmin identified by strmadmin using'peter';

创建从数据库数据库链
connect strmadmin/strmadmin

create public database link michael connect to strmadmin identified by strmadmin using 'michael.landun';//创建公用的DB_LINK,名称为”michael.landun”.
