迁移: （10g 64老机器，老存储） ------》（11g 64新机器，新存储）
注意要点：新老服务的时间，字符集，sid
升级顺序：10.2.0.1------>10.2.0.4或10.2.0.5---->11.2.0.1
新机器上安装2套oracle 目标11G数据库软件 和10g oracle软件
操作步骤完全一样，当 新库10g能打开时，关库，让新库11g 以 升级模式打开，升级库，即可
old：
1.关闭监听，和业务连接。先做全库备份：
lsnrctl stop
sqlplus as sysdba
alter system switch logfile;
alter system switch logfile;
$ rman target / log=/home/oracle/rman/log/dqianyi_rman.log
RMAN> backup database format '/home/oracle/backup/full_%d_%T_%s_%p.bak';
2.确定位置名称：
SQL> select file#,ts#,name from v$datafile;
FILE# TS# NAME
---------- ---------- ---------------------------------------------
1 0 /u01/app/ora10g/oradata/ora10g/system01.dbf
2 1 /u01/app/ora10g/oradata/ora10g/undotbs01.dbf
3 2 /u01/app/ora10g/oradata/ora10g/sysaux01.dbf
4 4 /u01/app/ora10g/oradata/ora10g/users01.dbf
3.备份数据文件,参数文件，控制文件
写成脚本：
[oracle@k214 log]$ cat x.sh
#!/bin/bash
rman target / log=/home/oracle/rman/log/1qianyi_rman.log << EOF
run
{allocate channel c1 type disk;
allocate channel c2 type disk;
copy
datafile '/u01/app/ora10g/oradata/ora10g/system01.dbf' to '/u01/new/system01.dbf',
datafile '/u01/app/ora10g/oradata/ora10g/undotbs01.dbf' to '/u01/new/undotbs01.dbf',
datafile '/u01/app/ora10g/oradata/ora10g/sysaux01.dbf' to '/u01/new/sysaux01.dbf',
datafile '/u01/app/ora10g/oradata/ora10g/users01.dbf' to '/u01/new/users01.dbf';
}
EOF
============================
备份控制文件
sqlplus / as sysdba
alter database backup controlfile to trace as '/home/oracle/new_ctl.sql';
RMAN> BACKUP CURRENT CONTROLFILE format '/home/oracle/arch/con_%d_%T_%s_%p.ctl'; --这步不需要
=============================
4. 打包数据文件并远程拷贝：
cd /u01
zip -qr new.zip new
scp -P22 /u01/new.zip 192.168.0.215:/u01/
下面5.6都是中断时间
5.备份归档 然后关机（关机开始中断）
#!/bin/bash
rman target / nocatalog log /home/oracle/rman/log/rman_arch.log append<<EOF
run
{allocate channel c1 type disk;
backup archivelog all format '/home/oracle/arch/arch_%d_%T_%s_%p';
}
shutdown immediate //备份归档可以分多次去做，但是最后一次做完要关机
EOF
6.打包和远程拷贝：
cd /home/oracle/
zip -qr arch.zip arch
scp -P22 /home/oracle/arch.zip 192.168.0.215:/u02/backup/
#7.拷贝redo 到new机器存储上
scp /u01/app/ora10g/oradata/ora10g/red* 192.168.0.215:/u01/new/
可以拷贝多次，最关键的就是最后一次。
===================================================================
new:
安装完11g 64 oracle软件，还没有建库，但是已经有监听了。
1.解压数据文件包和归档文件包
su - oracle
cd /u01 ;unzip new.zip
cd /u02/backup/ ;unzip arch.zip
2.修改参数文件并建立目录：
cat /u01/app/oracle/dbs/new.ora
orcl.__db_cache_size=67108864
orcl.__java_pool_size=4194304
orcl.__large_pool_size=4194304
orcl.__oracle_base='/u01/app'#ORACLE_BASE set from environment
orcl.__pga_aggregate_target=146800640
orcl.__sga_target=276824064
orcl.__shared_io_pool_size=0
orcl.__shared_pool_size=130023424
orcl.__streams_pool_size=8388608
*.audit_file_dest='/u01/app/admin/orcl/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.control_files='/u01/new/control01.ctl','/u01/new/control02.ctl','/u01/new/control03.ctl'
*.db_2k_cache_size=52428800
*.db_block_size=8192
*.db_domain=''
*.db_name='ora10g'
*.db_recovery_file_dest='/u01/app/flash_recovery_area'
*.db_recovery_file_dest_size=4039114752
*.diagnostic_dest='/u01/app'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
*.log_archive_dest_1='location=/u01/backup/arch'
*.log_archive_format='%t_%s_%r.dbf'
*.memory_target=422576128
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_tablespace='UNDOTBS1'
建立目录：
mkdir -p /u01/backup/arch
mkdir -p /u01/app/admin/orcl/adump
mkdir -p /u01/app/flash_recovery_area
3.启动oracle 到mount
SQL> startup nomount pfile=/u01/app/oracle/dbs/new.ora;
====================================
主库备份：
全部备份文件放在一个路径，顺序是 数据文件，归档，控制文件。
1.库全备：
backup database format='/home/oracle/rman/%U_%s.bak';
alter system archive log current
alter system switch logfile
2.归档全备：
BACKUP ARCHIVELOG ALL format='/home/oracle/rman/%U_%s.arc';
BACKUP ARCHIVELOG 命令比较灵活， ALL 是指备份当前所有可访问到的归档文件，你还可以通过 UNTIL 、 SCN 、 TIME 、 SEQUENCE 等参数灵活指定要备份的归档区间，这里不再一一演示，感兴趣的朋友可以自行尝试。
3.控制文件备份：
BACKUP CURRENT CONTROLFILE format='/home/oracle/rman/%U_%s.ctl';
cd /home/oracle
zip -qr rman.zip rman
scp rman.zip k101:/home/oracle/
备库：
存放rman备份集合的地方和主库一致（因为在修复控制文件后，修复数据库（restore）和恢复数据库（recover,需要归档的）这个时候通过控制文件找到响应的路径（主库所在的路径）
su- oracle
[oracle@k101 ~]$unzip rman.zip
[oracle@k101 rman]$ cd /home/oracle/rman
[oracle@k101 rman]$ ll
total 310428
-rw-r----- 1 oracle oinstall 291266560 Oct 9 02:13 01pkjad1_1_1_1.bak
-rw-r----- 1 oracle oinstall 7143424 Oct 9 02:13 02pkjadq_1_1_2.bak
-rw-r----- 1 oracle oinstall 12023296 Oct 9 02:32 03pkjbhr_1_1_3.arc
-rw-r----- 1 oracle oinstall 7110656 Oct 9 02:35 04pkjboa_1_1_4.ctl
rman>restore controlfile from '/home/oracle/rman/04pkjboa_1_1_4.ctl';
SQL>alter database mount;
rman>restore database from '/home/oracle/rman/04pkjboa_1_1_4.ctl';
RMAN> restore database; //修复数据库文件
RMAN> recover database; //先自动修复归档，然后恢复数据库文件，这里将报错
看报错信息，能看到rman归档追加到多少号了
=====================================
4.手动建立控制文件（由于之前远程拷贝redo，因此可以顺利打开）：
SQL>CREATE CONTROLFILE REUSE DATABASE "ORA10G" NORESETLOGS ARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292
LOGFILE
GROUP 1 '/u01/new/redo01.log' SIZE 50M,
GROUP 2 '/u01/new/redo02.log' SIZE 50M,
GROUP 3 '/u01/new/redo03.log' SIZE 50M
DATAFILE
'/u01/new/system01.dbf',
'/u01/new/undotbs01.dbf',
'/u01/new/sysaux01.dbf',
'/u01/new/users01.dbf'
CHARACTER SET ZHS16GBK
;
确定数据库是否为mount状态：
SQL> select status from v$instance;
STATUS
------------
STARTED
SQL> alter database mount;
Database altered.
5.建立spfile
SQL> create spfile from pfile='/u01/app/oracle/dbs/new.ora';
SQL>shutdown abort
SQL> startup;
Database mounted.
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/u01/new/system01.dbf'
6.让数据库识别新的rman备份集位置：
[oracle@k215 arch]$ rman target / log=/home/oracle/rman/log/know_qianyi_rman.log
RMAN> catalog start with '/u02/backup/arch/';
7.解压归档：
RMAN>recover database; //会报错，但是会自动解压归档
8.有了归档，就可以进行常规介质恢复：
SQL> recover database using backup controlfile until cancel;
/u01/backup/arch/1_16_860079637.dbf
SQL> recover database using backup controlfile until cancel;
/u01/new/redo01.log
SQL> recover database using backup controlfile until cancel;
/u01/new/redo02.log
SQL> recover database using backup controlfile until cancel;
/u01/new/redo03.log
Log applied.
Media recovery complete.
9.升级数据库(10.2.0.1------>10.2.0.4或10.2.0.5---->11.2.0.1)：
SQL> alter database open resetlogs upgrade;
SQL> shutdown immediate;
SQL> startup upgrade;
SQL> spool /home/oracle/patch.log
SQL> @?/rdbms/admin/catupgrd.sql
SQL> spool off
SQL> startup(数据库可以正常启动) 在运行下面的脚本（重新编译PL/SQL包，使其能够被使用）
SQL> @ /rdbms/admin/utlrp.sql
10.全备
