以下是小弟在使用db2move中的一些經(jīng)驗(yàn)，希望對(duì)大家有所幫助。?
?db2???connect???to??YOURDB???
連接數(shù)據(jù)庫(kù)?
?db2look?-d??YOURDB??-a?-e?-x?-o?creatab.sql?
導(dǎo)出建庫(kù)表的SQL?
?db2move???YOURDB??export?
用db2move將數(shù)據(jù)備份出來(lái)?
?vi???creatab.sql?
如要導(dǎo)入的數(shù)據(jù)庫(kù)名與原數(shù)據(jù)庫(kù)不同，要修改creatab.sql中CONNECT?項(xiàng)?
如相同則不用更改?
?db2move??NEWDB??load?
將數(shù)據(jù)導(dǎo)入新庫(kù)中?
在導(dǎo)入中可能因?yàn)榉N種原因發(fā)生中斷，會(huì)使數(shù)據(jù)庫(kù)暫掛?
db2????list?tablespaces???show???detail?

表名知道后到db2move.lst(在db2move??YOURDB??export的目錄中)中找到相應(yīng)的.ixf文件?
?db2?load?from?tab11.ixf?of?ixf?terminate?into?db2admin.xxxxxxxxx?
tab11.ixf對(duì)應(yīng)的是xxxxxxxxx表?
數(shù)據(jù)庫(kù)會(huì)恢復(fù)正常，可再用db2?list?tablespaces?show?detail查看
30.不能通過(guò)GRANT授權(quán)的權(quán)限有哪種?
