Oracle data pump 指令參照

預測dmp檔佔多少空間
expdp test/test directory=expdp_dir logfile=test_dmp.log estimate_only=y
                ESTIMATE=BLOCKS  (預設)
                ESTINATE=STATISTICS  (依照表格的STATISTICS預測空間大小)
指定dump時用幾個執行緒
expdp test/test  directory=expdp_dir dumpfile=test.dmp logfile=test_dmp.log parallel=4

排除某個表格
expdp test/test schemas=TEST exclude=TABLE:"in\('TEST'\)" directory=expdp_dir dumpfile=expdp.dmp logfile=expdp.log

排除某個USER
expdp \'/ as sysdba\' full=y EXCLUDE=SCHEMA:"in\('TEST'\)" directory=dp dumpfile=full.dmp logfile=full.log

排除一
expdp \'/ as sysdba\' full=y EXCLUDE=SCHEMA:"in\('WKSYS'\)" directory=dp dumpfile=full.dmp logfile=full.log CONTENT=METADATA_ONLY

expdp \'/ as sysdba\' full=y EXCLUDE=SCHEMA:"in\('WKSYS','OLAPSYS','TSMSYS','SYSMAN','OUTLN','WK_TEST'\)" directory=dp dumpfile=full.dmp logfile=full.log


匯出所有METADATA

by default, the datapump points to $ORACLE_BASE_admin/SID/dpdump
