OGG中各种数据泵的初始化脚本是什么,针对这个问题,这篇文章详细介绍了相对应的分析和解答,希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
一、先导元数据
## 导出元数据 (用户模式)
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_boss2_1_10_metadata_%U.dmp
exclude=statistics
logfile = expdp_boss2_1_10_metadata.log
parallel=4
schemas=(ucr_act21,
uop_act21,
ucr_act22,
uop_act22,
ucr_act41,
uop_act41,
ucr_act42,
uop_act42,
ucr_catalog,
uop_catalog)
content=metadata_only
##导入元数据 (用户模式)
userid ='system/system_cmcc_shsnc2018'
directory=BAK_DIR
dumpfile=expdp_boss2_2_metadata_%U.dmp
logfile = impdp_boss2_2_pk_index.log
parallel=4
schemas=('UIA_ACT21_STA',
'UIA_ACT22_STA',
'UIA_ACT41_STA',
'UIA_ACT42_STA',
'UIF_ACT21_BI',
'UIF_ACT21_STA',
'UIF_ACT22_BI',
'UIF_ACT22_STA',
'UIF_ACT41_BI',
'UIF_ACT41_STA',
'UIF_ACT42_BI',
'UIF_ACT42_STA',
'UIF_PARAM2',
'UIF_PARAM4')
content=metadata_only
INCLUDE=index,CONSTRAINT
remap_tablespace=(
TBS_ACT_DEF:TBS_ACT_HDACT08
USERS:TBS_ACT_HDACT08
TS_VB_ACCT_01:TBS_ACT_HDACT08
TS_VB_INTF_DAT:TBS_ACT_HDACT08
TS_VB_BASE_DAT:TBS_ACT_HDACT08
TS_VB_INFO:TBS_ACT_HIACT07
TS_VB_INTF_IND:TBS_ACT_HIACT07
)
########################################################
# 目标库disable相关对象
# 目标数据库重构并open后,需要diable trigger/job/cascade reference;
对应的disable脚本如下:
set echo off
set verify off
set feedback off
set pagesize 10000
set heading off
set linesize 200
set trim on
spool disable_ref.txt
select 'alter table '||owner||'.'||table_name||' disable constraint '||constraint_name||';'
from dba_constraints
where constraint_type in ('R') and owner = 'XPADRPT' and delete_rule='CASCADE' and status ='ENABLED';
spool off
spool disable_trigger.txt
select 'alter trigger '||owner||'.'||trigger_name||' disable;'
from dba_triggers where owner = 'XPADRPT' and STATUS='ENABLED';
spool off
spool disable_job.txt
select 'execute DBMS_IJOB.BROKEN('||job||',TRUE); commit;'
from dba_jobs
where schema_user = 'XPADRPT' and BROKEN='N';
spool off
########################################################
二、再导数据
#############################
— 会列出普通表与分区表
select owner,segment_name,sum(bytes)/1024/1024/1024 from dba_segments where owner='UCR_ACT41' and segment_type in ('TABLE','TABLE PARTITION') group by owner,segment_name order by sum(bytes)/1024/1024/1024 desc;
–列出(普通表+分区别总数)、分区总数
select owner,object_type,count(1) as"NUM" from dba_objects
where owner in ('TEST') and object_type in ('TABLE','TABLE PARTITION')
group by owner,object_type ;
— dba_tables 中包含普通表与分区表
#############################
2.1、用户模式到数据
##导出
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_UMT_ACT2_data_20180714_%U.dmp
exclude=statistics
logfile = expdp_UMT_ACT2_data_20180714.log
parallel=4
schemas=UMT_ACT2
content=data_only
compression=DATA_ONLY
##导入
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_UMT_ACT2_data_20180714_%U.dmp
exclude=statistics
logfile =impdp_UMT_ACT2_data_20180714.log
parallel=4
schemas=UMT_ACT2
2.2、表模式导数据
##导出
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_UCR_ACT42_1_2_20180715_%U.dmp
exclude=statistics
logfile = expdp_UCR_ACT42_1_2_20180715.log
parallel=4
tables=UCR_ACT42.TF_B_WRITEOFFLOG_D,UCR_ACT42.TI_OH_SMS_2015
content=data_only
compression=DATA_ONLY
##导入
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_UCR_ACT42_3_7_20180716_%U.dmp
logfile =impdp_UCR_ACT42_3_7_20180716.log
parallel=25
tables=UCR_ACT42.TF_B_SCORE_TRADELOG,
UCR_ACT42.TS_B_BILL_BEFORE,
UCR_ACT42.TF_BH_INTEGRALBILL_OLD,
UCR_ACT42.TP_INFOCHECK_RESULT_NEW,
UCR_ACT42.TF_B_PAYLOG
2.3、 某用户下排除特定表导其他表的数据
## 导出
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_UCR_ACT21_181_20180718_%U.dmp
logfile = expdp_UCR_ACT21_181_20180718.log
parallel=5
SCHEMAS=ucr_act21
content=data_only
compression=DATA_ONLY
exclude=statistics,TABLE:"IN ('XX','XX')"
## 导入
userid=system/system_cmcc_shsnc2018
directory=BAK_DIR
dumpfile=expdp_UCR_ACT21_181_20180718_%U.dmp
logfile = impdp_UCR_ACT21_181_20180718.log
parallel=25
SCHEMAS=ucr_act21
