同构异机迁移方案2_目标服务器仅安装数据库软件scp物理文件

作者：weixin_40725706 | 2024-02-07 09:47:23

踩

源端和目标端的数据库版本需要保持一致，补丁版本可以不一致，目标端磁盘空间不能小于源端空间，目标端只需要安装 Oracle 软件即可。

特别说明：本文档案例Oracle的安装路径不同，数据目录一致，采用scp的方式实现同构异机迁移。

迁移背景

	ip	os version	os user/password	db version	db user/password	数据量
源库	192.168.40.52	centos7.9 x86_64	root/dhh	11.2.0.4	sys/oracle	87G
目标库	192.168.40.152	centos7.9 x86_64	root/dhh	11.2.0.4	sys/oracle

由于源库服务器剩余的磁盘空间不是很多，采用scp的方式实现同构异机迁移，本文档案例Oracle的安装路径不同，数据目录一致。迁移步骤如下：

迁移前准备

源库

源库数据模拟

该步骤生产环境省略，纯属个人实验环境构建测试数据


--通过数据库主机连接
su - oracle
sqlplus / as sysdba
select sysdate from dual;
 
--操作系统上创建新的数据文件存放目录
[root@11g-db ~]# mkdir -p /data
[root@11g-db ~]# chown -R oracle:oinstall /data/
 
--创建表空间
--创建表空间，大小5m，开启自动扩展
create tablespace test datafile '/data/test01.dbf' size 5M autoextend on NEXT 1M MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;
 
--创建临时表空间
create temporary tablespace testtemp tempfile '/data/testtemp01.dbf'
size 50m autoextend on next 1m maxsize unlimited extent management local uniform size 4m;
 
##创建数据库用户
--创建用户，指定默认表空间和临时表空间
create user test identified by test default tablespace test temporary tablespace testtemp account unlock;
--赋予权限  最后的with admin option表示权限转授，可以把本身获得的权限再授权给其他用户
grant dba,connect,resource to test with admin option;
注意：密码最长30位
--切换用户
conn test/test
 
##创建表
 
create table test (id number primary key not null,name varchar2(100));
insert into test values (1,'hm');
insert into test values (2,'xk');
insert into test values (3,'whm');
commit;
 
 
create table t1 (id  int not null);
begin
  for i in 1..10000 loop
    insert into t1 values(dbms_random.value()*10000);
    --如果列是主键
    --insert into t1 values(i);
  end loop;
end;
/

源库生成参数文件

由于源库和目标库的安装目录不一致，所以需生成源库的参数文件传输到目标库进行更改。

--生成pfile参数文件

File created.

源库expdp全库备份(可选)

如果时间和磁盘空间允许，可先对源库进行expdp全库备份。本文档案例由于时间和磁盘空间紧张未做该步骤。


sqlplus / as sysdba
SQL>create directory dump_dir as '/oraDB/tmp_backup'
SQL>grant read,write on directory dump_dir to system;
expdp system/oracle directory=dump_dir dumpfile=backup.dmp full=y;

源库关库


--源库停止监听
su - oracle
[oracle@top130 ~]$ lsnrctl status
[oracle@top130 ~]$ lsnrctl stop
[oracle@top130 ~]$ lsnrctl stop
 
--源库杀用户连接 不建议 该步骤慎重 该文档未进行该操作
ps -ef|grep LOCAL=NO|awk '{print $2}'|xargs kill -9

由于源库和目标库内存cpu磁盘配置一样，因此后面参数文件不用更改内存参数，只用改路径就可以了。

安装数据库软件

采用脚本安装，该步骤省略。


--查$ORACLE_BASE
[oracle@syxk01:/home/oracle]$ echo $ORACLE_BASE
/oracle/app/oracle
 
--查$ORACLE_HOME
[oracle@syxk01:/home/oracle]$ echo $ORACLE_HOME
/oracle/app/oracle/product/11.2.0/db

扩展：静默安装数据库步骤

可参考如下：

创建用户

重建主机的Oracle用户组统一规范 uid gid 以保证共享存储挂接或其他需求的权限规范


groupadd -g 504 oinstall
groupadd -g 502 dba
useradd -g oinstall -G dba -u 502 oracle
passwd oracle

安装依赖包

安装好Oracle 需要的rpm包。安装rpm依赖包


rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh
挂载本地yum源
yum install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh

修改配置文件 /etc/security/limits.conf


oracle               soft     nproc    2047
oracle               hard     nproc    16384

oracle               hard     nofile   65536
oracle               soft     stack    10240

修改配置文件/etc/sysctl.conf


fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

重启主机或者输入命令 sysctl -p 生效当前配置

设置oracle 用户环境变量


export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=$PATH:$ORACLE_HOME/bin
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib64:/usr/lib64:/usr/local/lib64
export ORACLE_SID=orcl  #根据具体的填写
#如果设置NLS_LANG，容易产生导入sql或dmp出错，因为其他环境下的不是utf8
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
 
 
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
PATH=/usr/sbin:/usr/bin:/bin:/sbin:$ORACLE_HOME/bin export PATH

创建$ORACLE_BASE目录并赋予oracle目录权限：

mkdir -p /u01/app/oracle && chown -R oracle:oinstall /u01/app

上传数据库安装软件并用oracle 用户解压

静默安装

修改db_install.rsp文件参数


vi /home/oracle/database/response/db_install.rsp
####

传输物理文件

传输参数文件

源库传输参数文件至目标库

将源库/home/oracle/pfile_shipin04_bak_20240131.ora拷贝到目标库的/home/oracle目录。


--源库上操作  传输参数文件
su - oracle
[oracle@shipin04 ~]$ scp -P 422 pfile_shipin04_bak_20240131.ora oracle@172.18.1.130:/home/oracle/

由于源库和目标库内存cpu磁盘配置一样，因此参数文件不用更改内存参数，只用改路径就可以了。

目标库更改参数文件

参数文件中

shipin04.__oracle_base='/oracle/app'#ORACLE_BASE set from environment 为$ORACLE_BASE目录

*.audit_file_dest='/oracle/app/admin/shipin04/adump' 为$ORACLE_BASE目录/admin/shipin04/adump

.control_files中control02.ctl路径为$ORACLE_BASE目录/fast_recovery_area/shipin04/control02.ctl

.db_recovery_file_dest为$ORACLE_BASE目录/fast_recovery_area

.diagnostic_dest为$ORACLE_BASE目录


--目标库操作  备份已传输的参数文件，避免改的有问题重新从源库服务器传输到目标库服务器
[oracle@syxk01:/home/oracle]$ cp pfile_shipin04_bak_20240131.ora pfile_shipin04_bak_20240131.ora_bak02
 
--更改参数文件中的oracle_base目录为目标库的oracle_base目录
su - oracle
vi pfile_shipin04_bak_20240131.ora
:%s#/oracle/app#/oracle/app/oracle#g
更改参数文件中的控制文件路径/oracle/app/fast_recovery_area/shipin04/control02.ctl为
参数文件中的
/oracle/app/oracle/fast_recovery_area/shipin04/control02.ctl
 
语法说明：
:%s#源目录#新目录#g

更改后记得确认，避免更改错误。
