如上当前Oracle环境有几个问题

没有单独为oracle创建分区
oracle数据文件也存放路径不规范

现在需要单独为oracle创建分区，把对应的文件移动过去

创建文件系统

pvcreate /dev/sdb
vgcreate oravg /dev/sdb
lvcreate -n oralv -L 200000M oravg
mkfs.ext4 /dev/oravg/oralv
echo "/dev/oravg/oralv /oracle ext4 defaults 0 0" >> /etc/fstab
mkdir /oracle
mount /oracle



[root@testos ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              95G   18G   73G  20% /

/dev/mapper/oravg-oralv
                      193G   60M  183G   1% /oracle

创建目录和修改权限

mkdir -p /oracle/app/oracle/product/12.2.0/db_1
mkdir -p /oracle/app/oraInventory
mkdir -p /oracle/{oradata,backup,archive}
chown -R oracle:oinstall /oracle
chmod -R 775 /oracle

移动Oracle Home

关闭监听程序和数据库

如上找到最近的一次全备记录，正常restore的话，会恢复到之前的路径下，但是我们现在要做的是恢复到新的路径下

使用以下脚本进行恢复：

run{
set newname for datafile '/u01/app/oracle/oradata/testdb/system01.dbf' to '/oracle/oradata/system01.dbf';
set newname for datafile '/u01/app/oracle/oradata/testdb/sysaux01.dbf' to '/oracle/oradata/sysaux01.dbf';
set newname for datafile '/u01/app/oracle/oradata/testdb/undotbs01.dbf' to '/oracle/oradata/undotbs01.dbf';
set newname for datafile '/u01/app/oracle/oradata/testdb/users01.dbf' to '/oracle/oradata/users01.dbf';
restore database;
switch datafile all;
}

执行过程如下

RMAN> run{
2> set newname for datafile '/u01/app/oracle/oradata/testdb/system01.dbf' to '/oracle/oradata/system01.dbf';
3> set newname for datafile '/u01/app/oracle/oradata/testdb/sysaux01.dbf' to '/oracle/oradata/sysaux01.dbf';
4> set newname for datafile '/u01/app/oracle/oradata/testdb/undotbs01.dbf' to '/oracle/oradata/undotbs01.dbf';
5> set newname for datafile '/u01/app/oracle/oradata/testdb/users01.dbf' to '/oracle/oradata/users01.dbf';
6> restore database;
7> switch datafile all;
8> }

使用RMAN COPY 移动 Datafile 位置

1.查看datafile位置

SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
/oracle/app/oracle/oradata/LORCL19/system01.dbf
/oracle/app/oracle/oradata/LORCL19/sysaux01.dbf
/oracle/app/oracle/oradata/LORCL19/undotbs01.dbf
/oracle/app/oracle/oradata/LORCL19/users01.dbf
#创建一个新目录
mkdir -p /data/oradata

2.编写RMAN 脚本Rcopy.sh

export LANG=en_US
RMAN_LOG_FILE=${0}.out
ORACLE_HOME=/oracle/app/oracle/product/19.3.0/db
export ORACLE_HOME
RMAN=$ORACLE_HOME/bin/rman
export RMAN
ORACLE_SID=lorcl19
export ORACLE_SID
ORACLE_USER=oracle
export ORACLE_USER
echo "ORACLE_SID:$ORACLE_SID">>$RMAN_LOG_FILE
echo"ORACLE_HOME:$ORACLE_HOME">>$RMAN_LOG_FILE
echo"ORACLE_USER:$ORACLE_USER">>$RMAN_LOG_FILE
echo"==========================">>$RMAN_LOG_FILE
chmod 666 $RMAN_LOG_FILE
$RMAN nocatalog TARGET / msglog$RMAN_LOG_FILE append <<EOF
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
copy datafile '/oracle/app/oracle/oradata/LORCL19/system01.dbf' to '/data/oradata/system01.dbf';
copy datafile '/oracle/app/oracle/oradata/LORCL19/sysaux01.dbf' to '/data/oradata/sysaux01.dbf';
copy datafile '/oracle/app/oracle/oradata/LORCL19/undotbs01.dbf' to '/data/oradata/undotbs01.dbf';
copy datafile '/oracle/app/oracle/oradata/LORCL19/users01.dbf' to '/data/oradata/users01.dbf';
release channel c2;
release channel c1;
}
EOF
echo >> $RMAN_LOG_FILE
exit

3.将DB 启动到mount 状态

shutdown immediate
startup mount

4. 执行Rmancopy 脚本

crontab -l
00 11 * * * /u01/Rcopy.sh  &

#检查拷贝情况
ls

5. 对数据文件进行Rename

这里的Rename 操作更新datafile 在控制文件里的记录。注意的一点，控制文件不记录临时文件的信息，所以，临时文件rename不能rename。如果要对临时文件进行转移，可以对临时文件进行重建。这块内容具体参考：

alter database rename file '/oracle/app/oracle/oradata/LORCL19/system01.dbf' to '/data/oradata/system01.dbf';
alter database rename file '/oracle/app/oracle/oradata/LORCL19/sysaux01.dbf' to '/data/oradata/sysaux01.dbf';
alter database rename file '/oracle/app/oracle/oradata/LORCL19/undotbs01.dbf' to '/data/oradata/undotbs01.dbf';
alter database rename file '/oracle/app/oracle/oradata/LORCL19/users01.dbf' to '/data/oradata/users01.dbf';

6.打开DB并验证

alter database open;

#报错和处理
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/data/oradata/system01.dbf'

recovery datafile '/data/oradata/system01.dbf';
recover tablespace system;
recover database;
alter database open;



#查看数据文件
SQL> select file_name from dba_data_files;
