一 修改instance_name
将instance_name由dapuchai修改成cjcdb
1.1 停库
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
1.2 修改/etc/oratab
[oracle@cjc ~]$ vim /etc/oratab
#dapuchai:/u01/app/oracle/product/11.2.0/db_1:N
cjcdb:/u01/app/oracle/product/11.2.0/db_1:N
1.3 修改/home/oracle/.bash_profile
[oracle@cjc ~]$ vim .bash_profile
#export ORACLE_SID=dapuchai
export ORACLE_SID=cjcdb
1.4 修改生效
[oracle@cjc ~]$ source .bash_profile
[oracle@cjc ~]$ echo $ORACLE_SID
cjcdb
[oracle@cjc ~]$ env |grep ORACLE
ORACLE_SID=cjcdb
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
1.5 修改dbs目录下的文件名
