Oracle RAC資料庫修改名稱

Oracle RAC資料庫修改名稱

簡單記錄下Oracle RAC修改名稱的一些方法。

1.關閉一個執行個體

[oracle@rac11g2 ~]$ sqlplus / as sysdba

SQL> shutdown immediate;

2.備份spfile檔案

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

3.修改pfile檔案cluster_database為false

*.cluster_database=FALSE

4.使用pfile檔案，啟動單一實例資料庫到mount狀態

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

5.執行nid修改dbname

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

Connected to database ACCT (DBID=3809824099)

Connected to server version 11.2.0

Control Files in database:

+DATA_DG/acct/controlfile/current.261.872692963

+DATA_DG/acct/controlfile/current.260.872692963

Change database name of database ACCT to CRMDB? (Y/[N]) => Y

Proceeding with operation

Changing database name from ACCT to CRMDB

Instance shut down

Database name changed to CRMDB.

Modify parameter file and generate a new password file before restarting.

Succesfully changed database name.

DBNEWID - Completed succesfully.

6.修改ORACLE_SID資訊

------節點1------

6.1 環境變數

[oracle@rac11g1 ~]$ vi .bash_profile

export ORACLE_SID=crmdb1

6.2 口令檔案

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

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

6.3 修改pfile檔案啟動資料庫

*.cluster_database=TRUE

*.db_name='crmdb'

替換acct1為crmdb1 :%s/acct1/crmdb1/g

替換acct2為crmdb2 :%s/acct2/crmdb2/g

6.4 建立新的spfile參數檔案

[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 建立pfile參數檔案

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

[oracle@rac11g1 dbs]$ vi initcrmdb1.ora

SPFILE='+DATA_DG/crmdb/PARAMETERFILE/spfile.293.880105913'

------節點2------

1 環境變數

[oracle@rac11g2 ~]$ vi .bash_profile

export ORACLE_SID=crmdb2

2. 口令檔案

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

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

3. 參數檔案

[oracle@rac11g2 dbs]$ vi initcrmdb2.ora

SPFILE='+DATA_DG/crmdb/PARAMETERFILE/spfile.293.880105913'

7.修改crs資源

7.1 刪除舊執行個體配置

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

7.2 添加新執行個體配置

[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
