2. Grid software installation

1. Create grid users and groups

/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. Create a grid file directory

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. Configure grid environment variables

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/

##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*

Three, single instance data file migration to ASM disk group (RMAN)

1. Edit the parameter file to specify the new control file path

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. Start the database to nomount mode

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

Database Buffers	  553648128 bytes
Redo Buffers		    2355200 bytes

3. RMAN recovery control file

The essential:

1. Need to execute setasmgidwrap -o $ORACLE_HOME

2. After performing the previous step, you need to restart the database instance to nomount

3. Due to the use of RMAN, the archive mode needs to be turned on in advance

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

4. Start the database to mount mode

RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

5. RMAN Copy data file

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

6. RMAN Switch data file

RMAN> switch database to copy;

7, RMAN Switch temporary files, and open the database

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. Migrate redo log files

Key: Here, the order of DROP LOGFILE must be deleted from back to front, otherwise an error will be reported:
