修改RAC環(huán)境中的ASM DG名稱

--------------------------------------------------------------------------------------------------------

# 1. 生成數(shù)據(jù)文件重命名腳本

--------------------------------------------------------------------------------------------------------

---------------------------------------

--1.1 日志文件路徑替換

---------------------------------------

SQL > select 'ALTER DATABASE RENAME FILE '''||MEMBER||''' TO '''||REPLACE(MEMBER,'+ARCH_DG','+helloWorldARCH')||'''; ' FROM v$logfile where member like '%ARCH_DG%';

ALTER DATABASE RENAME FILE '+ARCH_DG/helloWorlddb/onlinelog/group_1.257.946749259' TO '+helloWorldARCH/helloWorlddb/onlinelog/group_1.257.946749259';

......

---------------------------------------

--1.2 日志文件路徑替換

---------------------------------------

SQL > select 'ALTER DATABASE RENAME FILE '''||MEMBER||''' TO '''||REPLACE(MEMBER,'+DATA01_DG','+helloWorldDATA1')||'''; ' FROM v$logfile where member like '%DATA01_DG%';

ALTER DATABASE RENAME FILE '+DATA01_DG/helloWorlddb/onlinelog/group_1.257.946749257' TO '+helloWorldDATA1/helloWorlddb/onlinelog/group_1.257.946749257';

......

---------------------------------------

--1.3 數(shù)據(jù)文件路徑替換

---------------------------------------

SQL > select 'ALTER DATABASE RENAME FILE '''||NAME||''' TO '''||REPLACE(NAME,'+DATA01_DG','+helloWorldDATA1')||'''; ' FROM v$datafile;

ALTER DATABASE RENAME FILE '+DATA01_DG/helloWorlddb/datafile/system.267.946748147' TO '+helloWorldDATA1/helloWorlddb/datafile/system.267.946748147';

......

---------------------------------------

--1.4 臨時文件路徑替換

---------------------------------------

SQL > select 'ALTER DATABASE RENAME FILE '''||NAME||''' TO '''||REPLACE(NAME,'+DATA01_DG','+helloWorldDATA1')||'''; ' FROM v$tempfile;

ALTER DATABASE RENAME FILE '+DATA01_DG/helloWorlddb/tempfile/temp.264.946748289' TO '+helloWorldDATA1/helloWorlddb/tempfile/temp.264.946748289';

......

---------------------------------------

--1.5 備份參數(shù)文件

---------------------------------------

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

--------------------------------------------------------------------------------------------------------

# 2. 停數(shù)據(jù)庫

--------------------------------------------------------------------------------------------------------

oracle@helloWorlddb1:[/home/oracle]srvctl config database -d helloWorlddb

oracle@helloWorlddb1:[/home/oracle]srvctl stop database -d helloWorlddb

--------------------------------------------------------------------------------------------------------

# 3. 重命名DG (grid用戶操作)

--------------------------------------------------------------------------------------------------------

---------------------------------------

--3.1 查看DG信息

---------------------------------------

grid@helloWorlddb1:[/home/grid]kfod a='/dev/rdisk/*' disks=all ds=true o=all?

grid@helloWorlddb1:[/home/grid]crsctl stat res -t

---------------------------------------

--3.2 刪除舊DG信息

---------------------------------------

grid@helloWorlddb1:[/home/grid]srvctl stop diskgroup -g ARCH_DG -n helloWorlddb1,helloWorlddb2 ?

grid@helloWorlddb1:[/home/grid]srvctl stop diskgroup -g DATA01_DG -n helloWorlddb1,helloWorlddb2 ?

grid@helloWorlddb1:[/home/grid]srvctl remove diskgroup -g ARCH_DG -f

grid@helloWorlddb1:[/home/grid]srvctl remove diskgroup -g DATA01_DG -f

---------------------------------------

--3.3 重命名DG

---------------------------------------

grid@helloWorlddb1:[/home/grid]renamedg dgname=DATA01_DG newdgname=helloWorldDATA1 asm_diskstring='/dev/rdisk/disk*' verbose=true

grid@helloWorlddb1:[/home/grid]renamedg dgname=ARCH_DG newdgname=helloWorldARCH asm_diskstring='/dev/rdisk/disk*' verbose=true

---------------------------------------

--3.4 查看新DG信息

---------------------------------------

grid@helloWorlddb1:[/home/grid]kfod a='/dev/rdisk/*' disks=all ds=true o=all?

---------------------------------------

--3.5 掛載新DG

---------------------------------------

grid@helloWorlddb1:[/home/grid]sqlplus / as sysasm

SQL> alter diskgroup helloWorldDATA1 mount;

SQL> alter diskgroup helloWorldARCH mount;

---------------------------------------

--3.6 檢查ASM實例中參數(shù)信息

---------------------------------------

SQL> show parameter asm_diskgroups;

--如果有需要，手工調(diào)整參數(shù)所對應(yīng)的磁盤組信息

SQL> alter system set asm_diskgroups=helloWorldDATA1,helloWorldARCH sid='+ASM1';

SQL> alter system set asm_diskgroups=helloWorldDATA1,helloWorldARCH sid='+ASM2';

---------------------------------------

--3.7 檢查crs資源信息

---------------------------------------

grid@helloWorlddb1:[/home/grid]crsctl stat res -t

--------------------------------------------------------------------------------------------------------

# 4. 修改數(shù)據(jù)庫相關(guān)DG路徑 (oracle用戶)

--------------------------------------------------------------------------------------------------------

---------------------------------------

--4.1 修改數(shù)據(jù)庫參數(shù)文件路徑 (兩個節(jié)點)

---------------------------------------

oracle@helloWorlddb1:[/home/oracle]cd $ORACLE_HOME/dbs

oracle@helloWorlddb1:[/oracle/app/oracle/11.2.0.4/db_1/dbs]vi inithelloWorlddb1.ora

oracle@helloWorlddb2:[/oracle/app/oracle/11.2.0.4/db_1/dbs]vi inithelloWorlddb2.ora

:%s/DATA01_DG/helloWorldDATA1/g

---------------------------------------

--4.2 修改crs中記錄的參數(shù)文件與DG信息

---------------------------------------

oracle@helloWorlddb1:[/home/oracle]srvctl modify database -d helloWorlddb -p +helloWorldDATA1/helloWorlddb/spfilehelloWorlddb.ora -a helloWorldDATA1,helloWorldARCH

---------------------------------------

--4.3 啟動數(shù)據(jù)庫到nomount狀態(tài)

---------------------------------------

oracle@helloWorlddb1:[/home/oracle]sqlplus / as sysdba

SQL> startup nomount;

---------------------------------------

--4.4 修改與DG名稱相關(guān)的數(shù)據(jù)庫參數(shù)

---------------------------------------

oracle@helloWorlddb1:[/home/oracle]grep DATA01_DG helloWorld.pfile ?

oracle@helloWorlddb1:[/home/oracle]grep ARCH_DG helloWorld.pfile

oracle@helloWorlddb1:[/home/oracle]sqlplus / as sysdba

alter system set control_files='+helloWorldDATA1/helloWorlddb/controlfile/current.265.946748283', '+helloWorldARCH/helloWorlddb/controlfile/current.256.946748283' scope=spfile;

alter system set db_create_file_dest='+helloWorldDATA1' scope=spfile;

alter system set db_create_online_log_dest_1='+helloWorldDATA1' scope=spfile;

alter system set db_create_online_log_dest_2='+helloWorldARCH' scope=spfile;

---------------------------------------

--4.5 重新啟動并掛載數(shù)據(jù)庫

---------------------------------------

SQL> shutdown immediate;

SQL> startup mount;

---------------------------------------

--4.6 執(zhí)行步驟1中生成的數(shù)據(jù)庫重命名腳本

---------------------------------------

---------------------------------------

--4.7 打開數(shù)據(jù)庫

---------------------------------------

SQL> alter database open;

---------------------------------------

--4.8 重啟集群進行驗證

---------------------------------------
