Oracle 11g OCM考纲Streams单向流复制

Oracle 11g OCM考纲Streams单向流复制

 

1.     实验环境

 

 

SYS user passwd:oracle

SYSTEM user password:oracle

 

节点1 节点2
Oracle SID Orcl Orcl
Global DB name/service Name Orcl1 Orcl2
Net server Name amer euro
字符集 AL32UTF8 AL32UTF8

 

 

 

2.检查和调整数据库参数

 

2.1 源端和目标端

tnsnames.ora 的配置:

vi /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

amer =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.199.118)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl1)

)

)

 

 

euro =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.199.225)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl2)

)

)

2.2数据库参数

参数 选项或值
Compatible 11.2.0.0.0(或更高)
global_names TRUE
service_names Orcl1 |orcl2
Processes 150
job_queue_processes 1000
memory_target 700M
memory_max_target 700M
sga_max_size 700M
streams_pool_size 200M

 

export ORACLE_SID=amer

sqlplus / as sysdba

show parameter compatible

show parameter global_names

alter system set global_names=true;

show parameter service_names

show parameter processes

show parameter memory_target

show parameter memory_max_target

show parameter sga_max_target

show parameter stream_pool_size

alter system set streams_pool_size=200M;

dbdao.com

调整globa_name和service_name:

源端:

alter database rename global_name to orcl1;

alter system set service_name=orcl1;

目标端:

alter database rename global_name to orcl2;

alter system set service_name=orcl2;

 

2.3确认归档模式

 

 

archive log list;

 

 

2.    流环境配置

 

 

 

3.1创建 表空间STREAMS_TBS,创建流用户 STRMADMIN使用此表空间并赋权。

 

 

源端和目标端:

创建表空间

create tablespace streams_tbs datafile ‘/u01/app/oracle/oradata/orcl/streams_tbs01.dbf’ size 25M;

创建用户:

create USER strmadmin identified by strmadmin  DEFAULT TABLESPACE streams_tbs  QUOTA UNLIMITED ON streams_tbs ;

赋权:

grant dba to strmadmin;

execute DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE(‘STRMADMIN’);

 

 

3.2创建目录对象

源端:

create directory SRC_EXP_DIR as ‘/home/oracle/amer’;

!mkdir -p /home/oracle/amer

 

目标端:

DIRECTORY_PATH (/hom/oracle/euro)中.

create directory DEST_EXP_DIR as ‘/home/oracle/euro’;

!mkdir -p /home/oracle/euro

dbdao.com

 

3.3创建DBlink

源端:

sqlplus strmadmin/strmadmin@amer

CREATE DATABASE LINK orcl2

CONNECT TO strmadmin

IDENTIFIED BY strmadmin USING ‘euro’;

 

目标端:

sqlplus strmadmin/strmadmin@euro

CREATE DATABASE LINK orcl1

CONNECT TO strmadmin

IDENTIFIED BY strmadmin USING ‘amer’;

 

 

4.配置复制和测试

在源端创建测试表:

sqlplus scott/scott@amer

set sqlprompt “AMER>”

create table dept_history as select * from dept;

dbdao.com

在目标端查询:

sqlplus scott/scott@euro

set sqlprompt “EURO>”

select count(*) from dept_history;

 

streams1

 

创建队列:

conn strmadmin/strmadmin

execute dbms_streams_adm.set_up_queue(queue_table => ‘strmadmin.queue_table’, queue_name => ‘strmadmin.queue_table’, queue_user => ‘STRMADMIN’);

创建进程:

源端端

conn strmadmin/strmadmin

execute dbms_streams_adm.add_schema_rules( schema_name => ‘scott’, streams_type => ‘capture’, streams_name => ‘capture_src’, queue_name => ‘strmadmin.queue_table’, include_dml => true, include_ddl => true);

目标端:

conn strmadmin/strmadmin

execute dbms_streams_adm.add_schema_rules( schema_name => ‘scott’, streams_type => ‘apply’, streams_name => ‘apply_dest’, queue_name => ‘strmadmin.queue_table’, include_dml => true, include_ddl => true, inclusion_rule => true);

使用expdp 进行数据初始化:

目标端

expdp strmadmin/strmadmin directory=DEST_EXP_DIR dumpfile=scott.dmp nologfile=Y network_link=ORCL1  schemas=scott

 

impdp strmadmin/strmadmin directory=DEST_EXP_DIR dumpfile=scott.dmp nologfile=Y remap_schema=scott:scott remap_tablespace=users:users table_exists_action=replace

 

 

#创建传播规则并修改propagation休眠时间为0,表示实时传播LCR。

源端:

connect strmadmin/strmadmin

execute dbms_streams_adm.add_schema_propagation_rules(schema_name => ‘scott’,streams_name => ‘prop_to_dest’,source_queue_name => ‘strmadmin.queue_table’,destination_queue_name => ‘strmadmin.queue_table@orcl2′, include_dml => true, include_ddl => true,source_database =>’orcl1’ );

 

execute dbms_aqadm.alter_propagation_schedule(queue_name => ‘strmadmin.queue_table’,destination => ‘orcl2′, destination_queue =>’strmadmin.queue_table’,latency => 0);

 

开启进程:

源端:

conn strmadmin/strmadmin

execute  dbms_capture_adm.start_capture(capture_name => ‘capture_src’);

目标端:

conn strmadmin/strmadmin

execute dbms_apply_adm.start_apply(apply_name => ‘apply_dest’);

 

在源端插入测试数据

insert into dept_history values (87, ‘Joe’, ‘jsmith’);

commit;

 

目标端再次查询:

select * from dept_history where DEPTNO=87;

streams2

 

5.其他

—停止进程:

exec dbms_capture_adm.stop_capture(capture_name => ‘capture_SRC ‘);
exec dbms_apply_adm.stop_apply(apply_name => ‘apply_dest’);
删除全部配置:

exec DBMS_STREAMS_ADM.remove_streams_configuration();
