一、环境准备

1、实验目的

（单台机器）将11.2.0.4的单实例数据库由文件系统，迁移到ASM单实例的磁盘组中，并注册到集群管理。

2、环境准备

项目 源库
操作系统 RHEL6.8
主机名 s11g
IP地址 192.168.56.20
数据库及版本 ORACLE11.2.0.4
数据库字符集 AL32UTF8
ORACLE SID orcl
数据文件目录 /oradata/orcl

3、ASM磁盘组规划

磁盘组名称 大小 冗余模式
OCR

5G

EXTERNAL
DATA 10G EXTERNAL

4、数据文件位置记录

/ORADATA/ORCL

--数据文件
SYS@orcl>select name from v$datafile;

NAME
------------------------------------------------------------
/oradata/orcl/system01.dbf
/oradata/orcl/sysaux01.dbf
/oradata/orcl/undotbs01.dbf
/oradata/orcl/users01.dbf
/oradata/orcl/example01.dbf
/oradata/orcl/ogg01.dbf

6 rows selected.

--控制文件
SYS@orcl>select name from v$controlfile;

NAME
------------------------------------------------------------
/oradata/orcl/control01.ctl
/u01/app/oracle/fast_recovery_area/orcl/control02.ctl

--临时文件
SYS@orcl>select name from v$tempfile;

NAME
------------------------------------------------------------
/oradata/orcl/temp01.dbf

--日志文件
SYS@orcl>select member from v$logfile;

MEMBER
------------------------------------------------------------
/oradata/orcl/redo03.log
/oradata/orcl/redo02.log
/oradata/orcl/redo01.log

SYS@orcl>show parameter pfile

NAME	TYPE	 VALUE
-----------------------------------------------------------------------------
spfile	string   /u01/app/oracle/product/11.2.0/db/dbs/spfileorcl.ora

二、Grid软件安装

1、创建grid用户和组

/usr/sbin/groupadd -g 1120 asmadmin 
/usr/sbin/groupadd -g 1121 asmdba
/usr/sbin/groupadd -g 1122 asmoper
/usr/sbin/useradd -u 1200 -g oinstall -G asmadmin,asmdba,asmoper,dba,oper grid
/usr/sbin/usermod -a -G asmdba oracle
echo "oracle" |passwd grid --stdin

2、创建grid文件目录

mkdir -p /u01/app/11.2.0/grid
mkdir -p /u01/app/grid
chown -R grid:oinstall /u01/app/grid
chown -R grid:oinstall /u01/app/11.2.0/grid
chown -R grid:oinstall /u01/app/oraInventory

3、配置grid环境变量

vi /home/grid/.bash_profile

export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid/
export ORACLE_SID=+ASM
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/rdbms/lib:/lib:/usr/lib:.
export LD_LIBRARY_PATH
SHLIB_PATH=$ORACLE_HOME/lib32:$ORACLE_HOME/rdbms/lib32:.
export SHLIB_PATH
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$ORACLE_HOME/bin:/usr/local/bin:/usr/bin:/usr/sbin:.
export PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib
export CLASSPATH
umask 022
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SRVM_REMOTESHELL=/usr/bin/ssh
export ORACLE_SRVM_REMOTECOPY=/usr/bin/scp
PS1=$LOGNAME@`hostname`:'$PWD''$ '
umask 022

4、udev+multipath绑定磁盘

--多路径绑定
yum install -y device-mapper*
mpathconf --enable --with_multipathd y
mv /etc/multipath.conf /etc/multipath.conf.bak >/dev/null 2>&1 
##配置multipath.conf
cat <<EOF >/etc/multipath.conf
defaults {
    user_friendly_names yes
}
 
blacklist {
  devnode "^sda"
}
EOF

multipath -F >/dev/null 2>&1 
multipath -v2 >/dev/null 2>&1 
multipath -ll

--绑定udev
##获取dm_uuid
cd /dev/mapper
for i in mpath*;
do
printf "%s %s\n" "$i" "$(udevadm info --query=all --name=/dev/mapper/$i |grep -i dm_uuid)">>udev_info;
done

##写入99-oracle-asmdevices.rules
cat /dev/mapper/udev_info |while read line 
do
dm_uuid=`echo $line |awk -F'=' '{print $2}'`;
disk_name=`echo $line|awk '{print $1}'`;
echo "KERNEL==\"dm-*\",ENV{DM_UUID}==\"${dm_uuid}\",SYMLINK+=\"asm_${disk_name}\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\"">>/etc/udev/rules.d/99-oracle-asmdevices.rules
done

udevadm control --reload-rules
udevadm trigger
ls -l /dev/asm*

5、用户资源配置

cat <<EOF >> /etc/security/limits.conf
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
EOF

6、安装CVU软件包

--上传grid安装包并解压
cd /soft
unzip -q /soft/p13390677_112040_Linux-x86-64_3of7.zip

--安装cvu软件包
yum install -y smartmontools

rpm -ivh /soft/grid/rpm/cvuqdisk-1.0.9-1.rpm

7、安装Grid软件

1、静默安装grid软件

**  安装模式：- HA_CONFIG  : To configure Grid Infrastructure for stand alone server**

--编辑grid.rsp静默安装响应文件

--静默安装
yum install -y openssh-clients

chown -R grid:oinstall /soft/grid/

rm -rf /u01/app/oraInventory/*

su - grid -c "/soft/grid/runInstaller -silent -showProgress -ignoreSysPrereqs -ignorePrereq -responseFile /soft/grid.rsp"

--执行root.sh脚本
/u01/app/11.2.0/grid/root.sh

--Create a file that contain all the asm password cfgrsp.properties
su - grid
cat <<EOF >>  /home/grid/cfgrsp.properties

EOF

--执行cfgrsp.properties脚本
/u01/app/11.2.0/grid/cfgtoollogs/configToolAllCommands RESPONSE_FILE=/home/grid/cfgrsp.properties

2、图形化安装

略

8、创建ASM磁盘组DATA

su - grid
sqlplus / as sysasm
SQL> create diskgroup DATA external redundancy disk '/dev/asm_mpathc';

Diskgroup created.

SQL> SELECT NAME,state FROM v$asm_diskgroup;

NAME											   STATE
-----------------------------------------------------------------------------------
OCR											       MOUNTED
DATA											   MOUNTED

select NAME,TOTAL_MB/1024 "TOTAL/G",FREE_MB/1024 "FREE/G",round(FREE_MB/TOTAL_MB*100)||'%' Per_Free,state from v$asm_diskgroup；
NAME			TOTAL/G     FREE/G PER_FREE		STATE
-------------------- ---------- ---------- -------------------- -------------------
OCR			     10         9.94238281 99%		MOUNTED

9、检查ASM实例

grid@s11g:/home/grid$ crsctl stat res -t
--------------------------------------------------------------------------------

三、单实例数据文件迁移至ASM磁盘组（RMAN）

1、编辑参数文件指定新的控制文件路径

SYS@orcl>create pfile='/home/oracle/pfile.ora' from spfile;

File created.

--修改参数文件
*.control_files='+DATA/orcl/controlfile/control01.ctl','+DATA/orcl/controlfile/control02.ctl'
*.db_recovery_file_dest='+DATA'
*.db_create_file_dest='+DATA'
*.log_archive_dest_1='location=+DATA'

2、启动数据库到nomount模式

SYS@orcl>shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

SYS@orcl>startup mount
ORACLE instance started.

Total System Global Area 1336176640 bytes
Fixed Size		    2253024 bytes
Variable Size		  838864672 bytes
Database Buffers	  486539264 bytes
Redo Buffers		    8519680 bytes
Database mounted.
SYS@orcl>alter database archivelog;

Database altered.

SYS@orcl>shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

SYS@orcl>
SYS@orcl>startup nomount pfile='/home/oracle/pfile.ora';
ORACLE instance started.

Total System Global Area  839282688 bytes
Fixed Size		    2257880 bytes
Variable Size		  281021480 bytes
Database Buffers	  553648128 bytes
Redo Buffers		    2355200 bytes

3、RMAN恢复控制文件

关键：

1、需要执行 setasmgidwrap -o $ORACLE_HOME

2、执行完上一步之后，需要重启数据库实例到nomount

3、由于使用RMAN，需要提前开启归档模式

RMAN> restore controlfile from '/oradata/orcl/control01.ctl';

Starting restore at 28-MAR-21
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=13 device type=DISK

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 03/28/2021 05:20:18

--这里由于oracle software是先于grid安装，所以权限不对
[oracle@s11g ~]$ ll /u01/app/oracle/product/11.2.0/db/bin/oracle
-rwxrwxr-x. 1 oracle oinstall 239626683 Mar 26 12:51 /u01/app/oracle/product/11.2.0/db/bin/oracle

--因此要先执行setasmgidwrap -o $ORACLE_HOME
grid@s11g:/u01/app/11.2.0/grid/bin$ setasmgidwrap -o /u01/app/oracle/product/11.2.0/db/bin/oracle

[root@s11g ~]# ll /u01/app/oracle/product/11.2.0/db/bin/oracle
-rwsr-s--x 1 oracle asmadmin 239626641 Mar 26 14:52 /u01/app/oracle/product/11.2.0/db/bin/oracle

--这里执行完之后，需要重启数据库实例，这一步很重要，不然报错
[oracle@s11g ~]$ rman target /

--恢复控制文件
RMAN> restore controlfile from '/oradata/orcl/control01.ctl';

Starting restore at 26-MAR-21
using target database control file instead of recovery catalog

channel ORA_DISK_1: copied control file copy
output file name=+DATA/orcl/controlfile/control01.ctl
output file name=+DATA/orcl/controlfile/control02.ctl
Finished restore at 26-MAR-21

4、启动数据库到mount模式

RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

5、RMAN Copy 数据文件

RMAN> backup as copy database format '+DATA';

6、RMAN Switch 数据文件

RMAN> switch database to copy;

7、RMAN Switch 临时文件，并打开数据库

run {
set newname for tempfile 1 to '+DATA';
switch tempfile all;
}

executing command: SET NEWNAME

renamed tempfile 1 to +DATA in control file

RMAN> alter database open;

database opened

8、迁移重做日志文件

关键：这里DROP LOGFILE时顺序要从后往前删，否则报错：

ERROR at line 1: ORA-00362: member is required to form a valid logfile in group 2 ORA-01517: log member: '/oradata/orcl/redo02.log’

--查看未迁移前的日志文件
SYS@orcl>set line222
col member for a60
SYS@orcl>SELECT a.group#, b.member, a.status FROM v$log a, v$logfile b WHERE a.group#=b.group#;

    GROUP# MEMBER							STATUS
---------- ------------------------------------------------------------ -----------
	 3 /oradata/orcl/redo03.log					INACTIVE
	 2 /oradata/orcl/redo02.log					CURRENT
	 1 /oradata/orcl/redo01.log					INACTIVE

--迁移过程（中间可以需要多次切换日志，将日志切换到INACTIVE才可以drop）
ALTER DATABASE ADD LOGFILE MEMBER '+DATA' TO GROUP 1;
ALTER DATABASE ADD LOGFILE MEMBER '+DATA' TO GROUP 2;
ALTER DATABASE ADD LOGFILE MEMBER '+DATA' TO GROUP 3;
ALTER SYSTEM SWITCH LOGFILE;
ALTER DATABASE DROP LOGFILE MEMBER '/oradata/orcl/redo03.log';
ALTER SYSTEM SWITCH LOGFILE;
ALTER DATABASE DROP LOGFILE MEMBER '/oradata/orcl/redo02.log';
ALTER SYSTEM SWITCH LOGFILE;
ALTER DATABASE DROP LOGFILE MEMBER '/oradata/orcl/redo01.log';
ALTER SYSTEM CHECKPOINT;


--迁移后的日志文件
SYS@orcl>SELECT a.group#, b.member, a.status FROM v$log a, v$logfile b WHERE a.group#=b.group#;

    GROUP# MEMBER							STATUS
---------- ------------------------------------------------------------ ----------------
	 1 +DATA/orcl/onlinelog/group_1.280.1068223535			INACTIVE
	 2 +DATA/orcl/onlinelog/group_2.281.1068223535			INACTIVE
	 3 +DATA/orcl/onlinelog/group_3.282.1068223535			CURRENT

9、服务器参数文件，并重启数据库

--查看spfile文件是否创建
SYS@orcl>show parameter pfile

NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
spfile				     string

--创建spfile文件
SYS@orcl>create spfile='+DATA/orcl/spfileorcl.ora' from pfile='/home/oracle/pfile.ora';

File created.

--查看生成的spfile文件
ASMCMD> ls
ARCHIVELOG/
CONTROLFILE/
DATAFILE/
ONLINELOG/
PARAMETERFILE/
TEMPFILE/
spfileorcl.ora

--修改dbs下spfile文件
cd $ORACLE_HOME/dbs
rm -rf spfileorcl.ora 

cat <<EOF >> initorcl.ora
spfile=+DATA/orcl/spfileorcl.ora
EOF

--重启数据库
shutdown immediate
startup

10、验证各文件存储位置（都已切换到ASM磁盘组DATA下）

select name from v$datafile 
union all
select name from v$tempfile 
union all
select member from v$logfile 
union all
select name from v$controlfile;

NAME
--------------------------------------------------------------------------------
+DATA/orcl/datafile/system.273.1068222147
+DATA/orcl/datafile/sysaux.274.1068222153
+DATA/orcl/datafile/undotbs1.276.1068222159
+DATA/orcl/datafile/users.278.1068222161
+DATA/orcl/datafile/example.275.1068222157
+DATA/orcl/tempfile/temp.279.1068223335
+DATA/orcl/onlinelog/group_1.280.1068223535
+DATA/orcl/onlinelog/group_2.281.1068223535
+DATA/orcl/onlinelog/group_3.282.1068223535
+DATA/orcl/controlfile/control01.ctl
+DATA/orcl/controlfile/control02.ctl

11 rows selected.


SYS@orcl>show parameter pfile

NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
spfile				     string	 +DATA/orcl/spfileorcl.ora

四、注册到Grid集群

[oracle@s11g ~]$ srvctl add database -d orcl -o /u01/app/oracle/product/11.2.0/db -p +DATA/orcl/spfileorcl.ora -n orcl -a DATA
