Oracle 单表流复制 stream
把Oracle单表流复制搞定,由于oracle stream 操作步骤多,之前遇到许多问题,没有理清思路或者说自己对此的理解不够,所以失败。
把Oracle单表流复制搞定,由于oracle stream 操作步骤多,之前遇到许多问题,
没有理清思路或者说自己对此的理解不够,所以失败。对于重要表,流复制类似dataguard应用日志,主服务器
捕获,然后传递,从服务器接受,如此而以。简单记录一下主要步骤。
1 主服务器 os: windows sid:rman 数据库版本10.2.0.1
从服务器 os: windows sid format 数据库版本10.2.0.1
2 主、从数据库分别执行如下的语句:
Sqlplus ‘/ as sysdba’
alter system set aq_tm_processes=2 scope=both;
alter system set global_names=true scope=both;
alter system set job_queue_processes=10 scope=both;
alter system set parallel_max_servers=20 scope=both;
alter system set undo_retention=3600 scope=both;
alter system set nls_date_format='YYYY-MM-DD HH24:MI:SS' scope=spfile;
alter system set streams_pool_size=25M scope=spfile;--这个我没执行,理由是oracle自动分配了
alter system set utl_file_dir='*' scope=spfile;
alter system set open_links=4 scope=spfile;
3 主从机设置归档 mout状态下alter database archivelog 另开启alter system set log_archive_start=true;
查看归档是否成功select recid, name, first_time from v$archived_log;
4 主从机表空间和用户
create tablespace stream_tbs datafile 'g:\oracle\oradata\rman\stream01.dbf' size 200m
autoextend on extent management local uniform size 1m segment space management auto;
表空间已创建。
-- 创建streams管理用户,并授予dba权限
JSSWEB> create user test identified by test default tablespace stream_tbs;
用户已创建。
--将logminer的数据字典从system表空间转移到新建的表空间,防止撑满system表空间
execute dbms_logmnr_d.set_tablespace('tbs_stream');
-- 由于streams用户操作需要较多权限,此处仅用于演示,简便期间直接授予dba权限
授权test管理用户
JSSWEB> grant dba to test;
begin
dbms_streams_auth.grant_admin_privilege(
grantee => 'test',
grant_privileges => true);
end;
5 主从机表空间和用户
create tablespace stream_tbs datafile 'd:\oracle\oradata\rman\stream01.dbf' size 200m
autoextend on extent management local uniform size 1m segment space management auto;
表空间已创建。
-- 创建streams管理用户,并授予dba权限
JSSWEB> create user strmadmin identified by strmadmin default tablespace stream_tbs;
用户已创建。
--将logminer的数据字典从system表空间转移到新建的表空间,防止撑满system表空间
execute dbms_logmnr_d.set_tablespace('tbs_stream');
-- 由于streams用户操作需要较多权限,此处仅用于演示,简便期间直接授予dba权限
授权test管理用户
JSSWEB> grant dba to strmadmin ;
begin
dbms_streams_auth.grant_admin_privilege(
grantee => 'strmadmin',
grant_privileges => true);
end;
6 配置网络连接
主数据库(tnsnames.ora)中添加从数据库的配置。
RMAN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
)
(CONNECT_DATA =
(SID = rman)
(SERVER = DEDICATED)
)
)
配置从环境tnsnames.ora
从数据库(tnsnames.ora)中添加主数据库的配置。
FORMAT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.104)(PORT = 1521))
)
(CONNECT_DATA =
(SID = format)
(SERVER = DEDICATED)
)
)
7 创建database link
主:create database link format connect to strmadmin identified by strmadmin using 'format';
从:create database link rman connect to strmadmin identified by strmadmin using 'rman ';
然后相互tnsping 或 select sysdate from dual@format/rman;
8 主库 exec dbms_streams_adm.set_up_queue();
从库 exec dbms_streams_adm.set_up_queue();
9 创建捕获规则
begin
dbms_streams_adm.add_table_rules(
table_name => 'scott.emp',
streams_type => 'capture',
streams_name =>'capture_stream',
queue_name => 'test.streams_queue',
include_dml => true,
include_ddl => true,
inclusion_rule => true);
end;
--创建传播规则
begin
dbms_streams_adm.add_table_propagation_rules(
table_name =>'scott.emp',
streams_name => 'sour_to_targ',
source_queue_name =>'test.streams_queue',
destination_queue_name => 'strmadmin.streams_queue@format',
include_dml => true,
include_ddl => true,
source_database =>'rman',
inclusion_rule => true,
queue_to_queue => true);
end;
select capture_name,status from dba_capture;
