Oracle RAC数据库修改名称

共计 2967 个字符，预计需要花费 8 分钟才能阅读完成。

简单记录下 Oracle RAC 修改名称的一些方法。

1. 关闭一个实例

[oracle@rac11g2 ~]$ sqlplus / as sysdba

SQL> shutdown immediate;

2. 备份 spfile 文件

SQL> create pfile=’/home/oracle/acct1.pfile’ from spfile;

3. 修改 pfile 文件 cluster_database 为 false

*.cluster_database=FALSE

4. 使用 pfile 文件，启动单实例数据库到 mount 状态

SQL> startup mount pfile=’/home/oracle/acct1.pfile’;

5. 执行 nid 修改 dbname

[oracle@rac11g1 ~]$ nid target=sys/oracle dbname=crmdb setname=y

6. 修改 ORACLE_SID 信息

—— 节点 1 ——

6.1 环境变量

[oracle@rac11g1 ~]$ vi .bash_profile

export ORACLE_SID=crmdb1

6.2 口令文件

[oracle@rac11g1 ~]$ cd $ORACLE_HOME/dbs

[oracle@rac11g1 dbs]$ orapwd file=orapwcrmdb1 password=oracle

6.3 修改 pfile 文件启动数据库

*.cluster_database=TRUE

*.db_name=’crmdb’

替换 acct1 为 crmdb1 :%s/acct1/crmdb1/g

替换 acct2 为 crmdb2 :%s/acct2/crmdb2/g

6.4 创建新的 spfile 参数文件

[oracle@rac11g1 ~]$ sqlplus / as sysdba

SQL> startup pfile=’/home/oracle/acct1.pfile’ nomount;

SQL> create spfile=’+DATA_DG’ from pfile=’/home/oracle/acct1.pfile’;

6.5 创建 pfile 参数文件

[oracle@rac11g1 ~]$ cd $ORACLE_HOME/dbs

[oracle@rac11g1 dbs]$ vi initcrmdb1.ora

SPFILE=’+DATA_DG/crmdb/PARAMETERFILE/spfile.293.880105913′

—— 节点 2 ——

1 环境变量

[oracle@rac11g2 ~]$ vi .bash_profile

export ORACLE_SID=crmdb2

2. 口令文件

[oracle@rac11g2 ~]$ cd $ORACLE_HOME/dbs

[oracle@rac11g2 dbs]$ orapwd file=orapwcrmdb2 password=oracle

3. 参数文件

[oracle@rac11g2 dbs]$ vi initcrmdb2.ora

SPFILE=’+DATA_DG/crmdb/PARAMETERFILE/spfile.293.880105913′

7. 修改 crs 资源

7.1 删除旧实例配置

[oracle@rac11g1 ~]$ srvctl remove database -d acct

7.2 添加新实例配置

[oracle@rac11g1 ~]$ srvctl add database -d crmdb -o /oracle/app/oracle/product/11.2.0/db_1/

[oracle@rac11g1 ~]$ srvctl add instance -d crmdb -i crmdb1 -n rac11g1

[oracle@rac11g1 ~]$ srvctl add instance -d crmdb -i crmdb2 -n rac11g2
