6 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 streams_tbs QUOTA UNLIMITED ON streams_tbs ; 赋权 : DEFAULT TABLESPACE 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'; dbdao.com IT 技术学习课件, 版权所有, 翻版必究 6

7 !mkdir -p /home/oracle/euro 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; 在目标端查询 : sqlplus scott/scott@euro set sqlprompt "EURO>" select count(*) from dept_history; 创建队列 : conn strmadmin/strmadmin execute dbms_streams_adm.set_up_queue(queue_table => 'strmadmin.queue_table', queue_nam e => 'strmadmin.queue_table', queue_user => 'STRMADMIN'); dbdao.com IT 技术学习课件, 版权所有, 翻版必究 7

8 创建进程 : 源端端 conn strmadmin/strmadmin execute dbms_streams_adm.add_schema_rules( schema_name => 'scott', streams_type => 'captu re', streams_name => 'capture_src', queue_name => 'strmadmin.queue_table', include_d ml => 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_na me => 'prop_to_dest',source_queue_name => 'strmadmin.queue_table',destination_queu e_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',dest ination => 'orcl2', destination_queue =>'strmadmin.queue_table',latency => 0); dbdao.com IT 技术学习课件, 版权所有, 翻版必究 8

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.

9 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; 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(); dbdao.com IT 技术学习课件, 版权所有, 翻版必究 9
