oracle修改數(shù)據(jù)庫(kù) 時(shí)間：2015-06-28 00:00:00 來(lái)源：IT貓撲網(wǎng) 作者：網(wǎng)管聯(lián)盟 我要評(píng)論(0)

　　在本例中，假設(shè)原來(lái)的數(shù)據(jù)庫(kù)名為test,要改成testdb,原實(shí)例名(service_name,instance_name)test,要改成testdb.

　　nid是自帶的工具，在oracle_home/bin目錄中.以下方法假設(shè)登陸到數(shù)據(jù)庫(kù)本機(jī)做。

　　1.1 sqlplus "sys/password as sysdba"

　　1.2 sql>shutdown immediate --先停掉數(shù)據(jù)庫(kù)

　　1.3 sql>startup mount --nid需要在mount狀態(tài)下才能做。

　　1.4sql>host nid target=sys/password dbname=new_dbname --nid是一個(gè)在操作系統(tǒng)下執(zhí)行的命令，在sqlplus環(huán)境中用host 去調(diào)用操作系統(tǒng)環(huán)境下的命令。命令中，當(dāng)你想將數(shù)據(jù)庫(kù)名字改為T(mén)ESTDB時(shí)，應(yīng)寫(xiě)成dbname=testdb

　　1.5執(zhí)行后程序會(huì)詢問(wèn)：

　　Change database ID and database name TEST to TESTDB? (Y/[N]) =>y

　　敲y確定。

　　之后程序會(huì)對(duì)控制文件，數(shù)據(jù)文件進(jìn)行修改：

　　Control File C:ORACLEORADATATESTCONTROL01.CTL - modified

　　Control File C:ORACLEORADATATESTCONTROL02.CTL - modified
