背景:
原来服务器连接的存储性能低下,现在需要使用一套新的存储.数据库为linux rac 11.2.0.4.
采用挂载新的磁盘组,手工切换ocr,vote disk和数据盘的方式进行迁移.下面的具体步骤
前提:
需要将新的磁盘组创建完成.下面就不描述创建新磁盘组的过程.
一.检查环境信息
1.检查当前的磁盘组,如下:
[grid@suq1 suq1]$ asmcmd
ASMCMD> lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name
MOUNTED EXTERN N 512 4096 1048576 3435 3329 0 3329 0 N BACKUP/
MOUNTED NORMAL N 512 4096 1048576 12288 6276 0 3138 0 N DATANEW/
MOUNTED EXTERN N 512 4096 1048576 12288 12193 0 12193 0 N LASTDATA/
MOUNTED NORMAL N 512 4096 1048576 6144 5859 2048 1905 0 N LASTOCR/
MOUNTED EXTERN N 512 4096 1048576 1458 1058 0 1058 0 Y SYSTEMDG/
2.检查ocr和vote disk:
[root@suq1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3412
Available space (kbytes) : 258708
ID : 1417062201
Device/File Name : +SYSTEMDG
Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Device/File not configured
Cluster registry integrity check succeeded
Logical corruption check succeeded
[root@suq1 ~]# crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 34e02ef82a944faebf20eb07ef074379 (/dev/raw/raw1) [SYSTEMDG]
说明:目前有磁盘组backup,datanew,lastdata,lastocr,systemdg,其中systemdg是现在的ocr和votedisk磁盘组.而datanew是现在的数据磁盘组.
现在需要将这两个磁盘组分别替换为lastocr和lastdata
二.更换ocr
在11gR2中可以在线替换ocr,但是在操作之前最好先做一个备份.
1.备份ocr
[root@suq1 ~]# ocrconfig -manualbackup
suq2 2019/12/08 00:10:41 /u01/11.2.0/grid/cdata/suq-cluster/backup_20191208_001041.ocr
2.添加ocr磁盘组
直接使用ocrconfig -add +LASTOCR来添加ocr,添加完成之后进行检查:
[root@suq1 ~]# ocrconfig -add +LASTOCR
[root@suq1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3472
Available space (kbytes) : 258648
ID : 1417062201
Device/File Name : +SYSTEMDG
Device/File integrity check succeeded
Device/File Name : +LASTOCR
Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Cluster registry integrity check succeeded
Logical corruption check succeeded
3.删除老的ocr
使用ocrconfig -delete +SYSTEMDG 来删除老的ocr,删除完成之后检查可以发现老的磁盘组已经从ocr中删除:
[root@suq1 ~]# ocrconfig -delete +SYSTEMDG
[root@suq1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3472
Available space (kbytes) : 258648
ID : 1417062201
Device/File Name : +LASTOCR
Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Device/File not configured
Cluster registry integrity check succeeded
Logical corruption check succeeded
到此ocr的替换已经完成了,但是此时我们还不能删除老的磁盘组,因为11g中vote disk也还在此磁盘组.
三.更换votedisk
1.查看当前的votedisk:
[root@suq1 ~]# crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 34e02ef82a944faebf20eb07ef074379 (/dev/raw/raw1) [SYSTEMDG]
Located 1 voting disk(s).
2.使用crsctl replace votedisk +LASTOCR来直接替换为新的votedisk
[root@suq1 ~]# crsctl replace votedisk +LASTOCR
Successful addition of voting disk 760cf80025964f18bfb1d1adda56884a.
Successful addition of voting disk 3ec1054a09d34f30bf35f3b0296c614c.
Successful addition of voting disk 57745829baca4f21bf22a78fa6e82a57.
Successful deletion of voting disk 34e02ef82a944faebf20eb07ef074379.
Successfully replaced voting disk group with +LASTOCR.
CRS-4266: Voting file(s) successfully replaced
[root@suq1 ~]# crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 760cf80025964f18bfb1d1adda56884a (/dev/raw/newocr1) [LASTOCR]
2. ONLINE 3ec1054a09d34f30bf35f3b0296c614c (/dev/raw/newocr2) [LASTOCR]
3. ONLINE 57745829baca4f21bf22a78fa6e82a57 (/dev/raw/newocr3) [LASTOCR]
Located 3 voting disk(s).
3.重建asm 参数文件
注意:上面的替换了ocr之后,并不会复制asm参数文件,所以需要手工重建参数文件
1
SQL> show parameter pfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string +SYSTEMDG/suq-cluster/asmparam
eterfile/registry.253.85093439
1
重建asm pfile:
SQL> create pfile='/u01/11.2.0/grid/dbs/init+asm.ora' from spfile;
File created.
SQL> create spfile='+LASTOCR' from pfile='/u01/11.2.0/grid/dbs/init+asm.ora';
File created.
上面操作后会自动修改spfile的位置,查看重建后的spfile位置:
[grid@suq1 suq1]$ asmcmd spget
+LASTOCR/suq-cluster/asmparameterfile/registry.253.1026434025
如果还不对可以在asmcmd中使用spset命令手工指定spfile位置.
4.重启crs,确认磁盘组能正常打开使用
[root@suq1 ~]# crsctl stat res -t
--------------------------------------------------------------------------------

四.删除老的ocr磁盘组
重启之后老的磁盘组默认为nomount的,你需要mount,然后执行删除:
SQL> select name,state from v$asm_diskgroup;
NAME STATE
------------------------------ -----------
BACKUP MOUNTED
DATANEW MOUNTED
LASTOCR MOUNTED
LASTDATA MOUNTED
SYSTEMDG DISMOUNTED
SQL> drop diskgroup systemdg including contents;
drop diskgroup systemdg including contents
*
ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15001: diskgroup "SYSTEMDG" does not exist or is not mounted
SQL> alter diskgroup systemdg mount;
Diskgroup altered.
SQL> drop diskgroup systemdg including contents;
Diskgroup dropped.
SQL> select name,state from v$asm_diskgroup;
NAME STATE
------------------------------ -----------
BACKUP MOUNTED
DATANEW MOUNTED
LASTOCR MOUNTED
LASTDATA MOUNTED
五.使用rman copy备份数据库(不需要停机)
在准备备份之前,可以先把归档日志的路径切换到新的磁盘组
建议在准备切换之前做,选择 业务量低的时候,这样滚日志的时间较短:
[oracle@suq1 ~]$ rman target /

六.切换数据库到新的磁盘组(需要停机)
[oracle@suq1 ~]$ rman target /
Recovery Manager: Release 11.2.0.4.0 - Production on Sun Dec 8 01:06:54 2019

七.修改controlfile和参数文件(需要停机)
上面完成之后是完成了数据文件的修改,还有控制文件,参数文件,日志文件,临时文件还放在原来的磁盘组中.
由于控制文件和参数文件不能在线修改,所以这里先修改控制文件,和参数文件,后面的日志文件和临时文件可以在线修改,放到后面再修改.
1.修改参数文件
在asmcmd中找到原来参数文件的位置,然后cp到新的位置,注意这里拷贝的是真实的spfile,而不是链接文件,例如:
ASMCMD> cp spfilesuq.ora.265.994003619 +LASTDATA/suq/spfilesuq.ora
copying +datanew/asm/PARAMETERFILE/spfilesuq.ora.265.994003619 -> +LASTDATA/suq/spfilesuq.ora
复制完成之后修改连个节点的$ORACLE_HOME/dbs/initSID.ora,将spfile指定到新的文件位置,例如:
spfile='+LASTDATA/suq/spfilesuq.ora'
如果集群中指定了spfile,则还需要修改集群中的参数文件位置
srvctl modify database -d suq -p '+LASTDATA/suq/spfilesuq.ora'
2.修改控制文件
同参数文件的,将控制文件拷贝到新的磁盘组的位置:
ASMCMD> cp control01.ctl +LASTDATA/suq/controlfile/control01.ctl
copying +DATANEW/suq/datafile/control01.ctl -> +LASTDATA/suq/controlfile/control01.ctl
ASMCMD> cp control01.ctl +LASTDATA/suq/controlfile/control02.ctl
copying +DATANEW/suq/datafile/control01.ctl -> +LASTDATA/suq/controlfile/control02.ctl
再在参数文件中修改控制文件的位置:
SQL> alter system set control_files='+LASTDATA/suq/controlfile/control01.ctl','+LASTDATA/suq/controlfile/control02.ctl' scope=spfile;
最后重启数据库:
[grid@suq1 ~]$ srvctl start database -d suq
到此数据库停机部分已经完成.检查参数文件和控制文件:
[oracle@suq1 dbs]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on Sun Dec 8 01:23:38 2019
Copyright (c) 1982, 2013, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Data Mining and Real Application Testing options
SQL> show parameter spfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string +LASTDATA/suq/spfilesuq.ora
SQL> show parameter control
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer 7
control_files string +LASTDATA/suq/controlfile/cont
rol01.ctl, +LASTDATA/suq/contr
olfile/control02.ctl
control_management_pack_access string DIAGNOSTIC+TUNING
八,修改日志文件和临时文件
此时的日志文件和临时文件都还在老的磁盘组中:
SQL> select member from v$logfile;
MEMBER
--------------------------------------------------------------------------------
+DATANEW/suq/datafile/redo01.log
+DATANEW/suq/datafile/redo02.log
+DATANEW/suq/datafile/redo03.log
+DATANEW/suq/datafile/redo08.log
+DATANEW/suq/datafile/redo09.log
+DATANEW/suq/datafile/redo10.log
6 rows selected.
SQL> select name from v$tempfile;
NAME
--------------------------------------------------------------------------------
+DATANEW/suq/tempfile/temp2.264.994003965
这些文件可以在线重建.
1.重建temp表空间,注意tempfile目录需要先创建
1.创建新的临时表空间
SQL> create temporary tablespace temp2 tempfile '+LASTDATA';
Tablespace created.
2.将数据库的默认临时表空间设置到新的临时表空间
SQL> alter database default temporary tablespace temp2;
Database altered.
3.删除老的临时表空间
SQL> drop tablespace temp including contents and datafiles;
Tablespace dropped.
SQL> select name from v$tempfile;
NAME
--------------------------------------------------------------------------------
+LASTDATA/suq/tempfile/temp.266.1026437279
2.重建redo log group
这里采用在原来的log group中添加新的member到磁盘组,然后再删除老的member的方法:
SQL> select 'alter database add logfile member ''+LASTDATA/suq/onlinelog'||substr(member,length(member)-INSTR(reverse(member),'/')+1,INSTR(reverse(member),'/'))||''' to group '||group#||';' from v$logfile where type='ONLINE';
'ALTERDATABASEADDLOGFILEMEMBER''+LASTDATA/SUQ/ONLINELOG'||SUBSTR(MEMBER,LENGTH(MEMBER)-INSTR(REVERSE(MEMBER),'/')+1,INSTR(REVERSE(MEMBER),'/'))||'''TOGROUP'||GROUP#||';'
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
alter database add logfile member '+LASTDATA/suq/onlinelog/redo01.log' to group 1;
alter database add logfile member '+LASTDATA/suq/onlinelog/redo02.log' to group 2;
alter database add logfile member '+LASTDATA/suq/onlinelog/redo03.log' to group 3;
alter database add logfile member '+LASTDATA/suq/onlinelog/redo08.log' to group 8;
alter database add logfile member '+LASTDATA/suq/onlinelog/redo09.log' to group 9;
alter database add logfile member '+LASTDATA/suq/onlinelog/redo10.log' to group 10;
首先将redo日志进行多切换几组,然后再删除,如果遇到current的group,则将日志再进行切换:
SQL> select 'alter database drop logfile member '''||member||''';' from v$logfile where member not like '+LASTDATA%' and type='ONLINE';
'ALTERDATABASEDROPLOGFILEMEMBER'''||MEMBER||''';'
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
alter database drop logfile member '+DATANEW/suq/datafile/redo01.log';
alter database drop logfile member '+DATANEW/suq/datafile/redo02.log';
alter database drop logfile member '+DATANEW/suq/datafile/redo03.log';
alter database drop logfile member '+DATANEW/suq/datafile/redo08.log';
alter database drop logfile member '+DATANEW/suq/datafile/redo09.log';
alter database drop logfile member '+DATANEW/suq/datafile/redo10.log';
到此所有的文件都已经完成了切换,下面开始检查所有的文件:
SQL> select status from v$instance;
STATUS
------------
OPEN
SQL> select name from v$datafile;
NAME
----------------------------------------------------------------------
+LASTDATA/suq/datafile/system.256.1026435747

+LASTDATA/suq/datafile/undotbs1.258.1026435787
+LASTDATA/suq/datafile/users.261.1026435799
+LASTDATA/suq/datafile/undotbs2.259.1026435795
SQL> select name from v$tempfile;

----------------------------------------------------------------------
+LASTDATA/suq/tempfile/temp.266.1026437279
SQL> select member from v$logfile;

+LASTDATA/suq/onlinelog/redo03.log
+LASTDATA/suq/onlinelog/redo08.log
+LASTDATA/suq/onlinelog/redo09.log
+LASTDATA/suq/onlinelog/redo10.log
6 rows selected.
SQL> show parameter spfile

需要先在另一个节点将磁盘组dismount,然后进行删除:
SQL> drop diskgroup datanew including contents;
drop diskgroup datanew including contents
*
ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15073: diskgroup DATANEW is mounted by another ASM instance
SQL> drop diskgroup datanew including contents;
Diskgroup dropped
磁盘组删除完成之后,但是集群资源中还有,因此还需要在集群中删除磁盘组资源
