之前几天一直再弄Oracle stream
只知道有Capture Staging Apply
然后就不学走先学跑的完成以下动作
3.1 Stop Capture
connect /@THAMW;
BEGIN
DBMS_CAPTURE_ADM.STOP_CAPTURE(capture_name => 'STREAM_CAPTURE');
END;
/
3.2 Stop apply
connect /@THAMR;
BEGIN
DBMS_APPLY_ADM.STOP_APPLY(apply_name => 'STREAM_APPLY');
END;
/
3.3 Add APPLY rules in destination site
connect /@THAMR;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'THAMWDA1.WILLIAM',
streams_type => 'APPLY',
streams_name => 'STREAM_APPLY',
queue_name => '.STREAM_Q',
include_dml => true,
include_ddl => true,
source_database => 'THAMW',
inclusion_rule => true);
END;
/
3.4 Setup DML handler for APPLY in destination site 4 types )
connect /@THAMR;
BEGIN
DBMS_APPLY_ADM.SET_DML_HANDLER(
object_name => 'THAMWDA1.WILLIAM',
object_type => 'TABLE',
operation_name => 'INSERT',
error_handler => false,
user_procedure => '.DML_HANDLER_APPEND',
apply_database_link => NULL,
apply_name => NULL );
END;
/
BEGIN
DBMS_APPLY_ADM.SET_DML_HANDLER(
object_name => 'THAMWDA1.WILLIAM',
object_type => 'TABLE',
operation_name => 'UPDATE',
error_handler => false,
user_procedure => '.DML_HANDLER_APPEND',
apply_database_link => NULL,
apply_name => NULL );
END;
/
BEGIN
DBMS_APPLY_ADM.SET_DML_HANDLER(
object_name => 'THAMWDA1.WILLIAM',
object_type => 'TABLE',
operation_name => 'DELETE',
error_handler => false,
user_procedure => '.DML_HANDLER_APPEND',
apply_database_link => NULL,
apply_name => NULL );
END;
/
3.5 Setup DML error handler for APPLY in destination site
connect /@THAMR;
BEGIN
DBMS_APPLY_ADM.SET_DML_HANDLER(
object_name => 'THAMWDA1.WILLIAM',
object_type => 'TABLE',
operation_name => 'INSERT',
error_handler => true,
user_procedure => '.errors_pkg.regions_pk_error',
apply_database_link => NULL,
apply_name => NULL);
END;
/
3.6 Add Capture rules in source site
connect /@THAMW;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'THAMWDA1.WILLIAM',
streams_type => 'CAPTURE',
streams_name => 'STREAM_CAPTURE',
queue_name => '.STREAM_Q',
include_dml => true,
include_ddl => true,
inclusion_rule => true,
source_database => 'THAMW');
END;
/
3.7 Add propagation rules in source site
connect /@THAMW;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_PROPAGATION_RULES
(
table_name => 'THAMWDA1.WILLIAM',
streams_name =>'STREAM_PROP',
source_queue_name => '.STREAM_Q',
destination_queue_name => '.STREAM_Q@THAMR',
include_dml => true,
include_ddl => true,
source_database => 'THAMW',
inclusion_rule => true
);
END;
/
3.8 Create schema and add columns in destination site (3 types )
/*导出，导入格式*/
host exp /@THAMW tables=THAMWDA1.WILLIAM ROWS=N
host imp /@THAMR fromuser=THAMWDA1 touser=THAMWDA1 ignore=y
connect /@THAMR;
ALTER TABLE THAMWDA1.WILLIAM
ADD (
TRANS_OPERATION VARCHAR2(1) DEFAULT 'I' NOT NULL,
T_STAMP VARCHAR2(26 byte) DEFAULT
SUBSTR(TO_CHAR(SYSTIMESTAMP,'YYYY-MM-DD HH24.MI.SSxFF'),1,26) NOT NULL ,
TRANS_FLAG VARCHAR2(1) DEFAULT 'Y' NOT NULL) ;
3.9 Table instantiation
/*导出数据*/
host exp /@THAMW tables=THAMWDA1.WILLIAM object_consistent=y
file=/oracle/THAMWDA1.WILLIAM.dmp
在destination site依次�行：
connect /@THAMR
truncate table THAMWDA1.WILLIAM;
alter table THAMWDA1.WILLIAM drop supplemental log data (primary key,
unique, foreign key) columns;
/*导入数据*/
host imp /@THAMR fromuser=THAMWDA1 touser=THAMWDA1 ignore=y
streams_instantiation=y STREAMS_CONFIGURATION=y
file=/oracle/THAMWDA1.WILLIAM.dmp
connect /@THAMR
alter table THAMWDA1.WILLIAM drop supplemental log data (primary key,
unique, foreign key) columns;
3.10 �定not compare old value （capture)
BEGIN
DBMS_APPLY_ADM.COMPARE_OLD_VALUES(
object_name => 'THAMWDA1.WILLIAM',
column_list => '*',
operation => '*',
compare => false);
END;
/
3.11 Start APPLY in destination site
connect /@THAMR;
BEGIN
DBMS_APPLY_ADM.START_APPLY(apply_name => 'STREAM_APPLY');
END;
/
3.12 Start CAPTURE in source site
connect /@THAMW;
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE(capture_name => 'STREAM_CAPTURE');
END;
/
注意：在原表的格式如下
CREATE TABLE WILLIAM
(
SID VARCHAR2(16 BYTE)
)
TABLESPACE MPPTUSR1
PCTUSED 0
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE (
INITIAL 1M
NEXT 1M
MINEXTENTS 1
MAXEXTENTS 2147483645
PCTINCREASE 0
BUFFER_POOL DEFAULT
)
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
结果是只能同步到Insert不能同步Update、delete
然后师傅说是没有INDEX的原因
我也不知道为什么
然后这样就可以了
CREATE TABLE WILLIAM
(
SID VARCHAR2(16 BYTE)
)
TABLESPACE MPPTUSR1
PCTUSED 0
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE (
INITIAL 1M
NEXT 1M
MINEXTENTS 1
MAXEXTENTS 2147483645
PCTINCREASE 0
BUFFER_POOL DEFAULT
)
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
ALTER TABLE WILLIAM ADD (
PRIMARY KEY
(SID)
USING INDEX
TABLESPACE MPPTIDX1
PCTFREE 10
INITRANS 2
MAXTRANS 255
STORAGE (
INITIAL 512K
NEXT 512K
MINEXTENTS 1
MAXEXTENTS 2147483645
PCTINCREASE 0
));
估计是这行出现了问题：
alter table THAMWDA1.WILLIAM drop supplemental log data (primary key,
unique, foreign key) columns;
究竟为什么还是不清楚
