记一次linux安装oracle12c及数据库整库物理迁移

因工作需要，要把数据库从服务器A迁到服务器B。

1.在服务器B搭建数据库环境

1.1 安装依赖包

yum install binutils -y
yum install compat-libcap1 -y
yum install compat-libstdc++-33 -y
yum install compat-libstdc++-33.i686 -y
yum install glibc -y
yum install glibc.i686 -y
yum install glibc-devel -y
yum install glibc-devel.i686 -y
yum install ksh -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -y
yum install libX11 -y
yum install libX11.i686 -y
yum install libXau -y
yum install libXau.i686 -y
yum install libXi -y
yum install libXi.i686 -y
yum install libXtst -y
yum install libXtst.i686 -y
yum install libgcc -y
yum install libgcc.i686 -y
yum install libstdc++ -y
yum install libstdc++.i686 -y
yum install libstdc++-devel -y
yum install libstdc++-devel.i686 -y
yum install libxcb -y
yum install libxcb.i686 -y
yum install make -y
yum install nfs-utils -y
yum install net-tools -y
yum install smartmontools -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -y

1.2创建oracle用户组和用户

# groupadd dba

# useradd -g dba oracle

# passwd oracle

# id oracle

1.3切换oracle用户配置bash_profile文件

# su – oracle

# vi .bash_profile

 

# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=; export TMPDIR
ORACLE_HOSTNAME=localhost.localdomain; export ORACLE_HOSTNAME
ORACLE_UNQNAME=headdb; export ORACLE_UNQNAME
ORACLE_BASE=/opt/oracle; export ORACLE_BASE
ORACLE_HOME=${ORACLE_BASE}/product/12.2.0.1/dbhome_1; export ORACLE_HOME
ORACLE_SID=headdb; export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH export PATH
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK;export NLS_LANG
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

修改完保存并编译文件（ps：i进入编辑状态，esc进入命令状态，:wq保存并推出，:q不保存退出，:q!有修改的强制不保存退出）

# source ~/.bash_profile

1.4下载并上传oracle安装包到服务器B

oracle12c下载地址：https://www.oracle.com/database/technologies/oracle-database-software-downloads.html

使用root用户解压并赋权

# chown -R oracle:dba  /home/oracle/database

# chmod -R 755 /home/oracle /database

1.5修改oracle安装响应文件db_install.rsp

 

#-------------------------------------------------------------------------------
# Do not change the following system generated value.
#-------------------------------------------------------------------------------
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_sch
ema_v12.2.0

#-------------------------------------------------------------------------------
# Specify the installation option.
# It can be one of the following:
#   - INSTALL_DB_SWONLY
#   - INSTALL_DB_AND_CONFIG
#   - UPGRADE_DB
#-------------------------------------------------------------------------------
oracle.install.option=INSTALL_DB_SWONLY

#-------------------------------------------------------------------------------
# Specify the Unix group to be set for the inventory directory.
#-------------------------------------------------------------------------------
UNIX_GROUP_NAME=dba

#-------------------------------------------------------------------------------
# Specify the location which holds the inventory files.
# This is an optional parameter if installing on
# Windows based Operating System.
#-------------------------------------------------------------------------------
INVENTORY_LOCATION=/opt/oracle/oraInventory
#-------------------------------------------------------------------------------
# Specify the complete path of the Oracle Home.
#-------------------------------------------------------------------------------
ORACLE_HOME=/opt/oracle/product/12.2.0.1/dbhome_1

#-------------------------------------------------------------------------------
# Specify the complete path of the Oracle Base.
#-------------------------------------------------------------------------------
ORACLE_BASE=/opt/oracle

#-------------------------------------------------------------------------------
# Specify the installation edition of the component.
#
# The value should contain only one of these choices.
#   - EE     : Enterprise Edition
#   - SE2     : Standard Edition 2

#-------------------------------------------------------------------------------

oracle.install.db.InstallEdition=EE

oracle.install.db.OSBACKUPDBA_GROUP=dba

#------------------------------------------------------------------------------
# The OSDGDBA_GROUP is the OS group which is to be granted SYSDG privileges.
#------------------------------------------------------------------------------
oracle.install.db.OSDGDBA_GROUP=dba

#------------------------------------------------------------------------------
# The OSKMDBA_GROUP is the OS group which is to be granted SYSKM privileges.
#------------------------------------------------------------------------------
oracle.install.db.OSKMDBA_GROUP=dba

#------------------------------------------------------------------------------
# The OSRACDBA_GROUP is the OS group which is to be granted SYSRAC privileges.
#------------------------------------------------------------------------------
oracle.install.db.OSRACDBA_GROUP=dba
 

保存并退出

1.6转到database目录执行安装命令

# ./runInstaller -ignoreSysPrereqs -ignorePrereq -waitforcompletion \ -showProgress -silent -responseFile /home/oracle/database/response/db_install.rsp

安装完切换root用户执行命令

# /opt/oracle/oraInventory/orainstRoot.sh
# /opt/oracle/root.sh

切换到oracle用户

# su - oracle

# sqlplus / as sysdba

数据库安装成功

2.数据库迁移

2.1找到服务器A的pfile、control_files和数据库实例路径

show parameter pfile
show parameter control_files

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

2.2创建pfile

create pfile from spfile;

2.3shutdown服务器A的数据库

shutdown immediate

2.4把数据库实例文件迁移到服务器B

2.5把服务器A生成的pfile移到服务器并修改路径为服务器B的数据库路径

headdb.__data_transfer_cache_size=0
headdb.__db_cache_size=1845493760
headdb.__inmemory_ext_roarea=0
headdb.__inmemory_ext_rwarea=0

*.sga_target=2394m
*.undo_tablespace='UNDOTBS1'
 

保存并退出

注：service 要改成新库的名称；audit_file_dest目录不存在要mkdir

注2：新迁移过来的文件要用root用户把权限赋给oracle用户

2.6登录oracle用户，连接sqlplus

startup nomount pfile='$ORACLE_HOME/dbs/initheaddb.ora'

alter database mount;

2.7查询数据文件、日志文件、临时文件路径并修改为新服务器路径

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

alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/system01.dbf' to '/home/oracleIns/oradata/headdb/system01.dbf'
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/sysaux01.dbf' to '/home/oracleIns/oradata/headdb/sysaux01.dbf';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/undotbs01.dbf' to '/home/oracleIns/oradata/headdb/undotbs01.dbf';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/TS_wolf.dbf' to '/home/oracleIns/oradata/headdb/TS_name.dbf';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/users01.dbf' to '/home/oracleIns/oradata/headdb/users01.dbf';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/temp01.dbf' to '/home/oracleIns/oradata/headdb/temp01.dbf';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo03.log' to '/home/oracleIns/oradata/headdb/redo03.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo02.log' to '/home/oracleIns/oradata/headdb/redo02.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo01.log' to '/home/oracleIns/oradata/headdb/redo01.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo04.log' to '/home/oracleIns/oradata/headdb/redo04.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo05.log' to '/home/oracleIns/oradata/headdb/redo05.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo06.log' to '/home/oracleIns/oradata/headdb/redo06.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo07.log' to '/home/oracleIns/oradata/headdb/redo07.log';
alter database rename file '/u01/app/oracle/product/12.2.0/oradata/headdb/redo08.log' to '/home/oracleIns/oradata/headdb/redo08.log';

打开数据库

alter database open;

用pfile创建spfile

create spfile from pfile;

2.8配置监听文件

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME =  headdb)
      (ORACLE_HOME = /opt/oracle/product/12.2.0.1/dbhome_1)
      (SID_NAME = headdb)
    )
  )
  
LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
  )

2.9打开监听

lsnrctl start

如果状态为unknow，连接sql，执行注册

alter system register;

退出查看监听状态lsnrctl status，若为ready则监听启动成功

至此数据库迁移成功
