ORACLE热备复制数据库全记录（可以修改数据库名和数据文件路径）

oralce热备是最简单，速度最快的数据库复制方法，以下是我的全部记录：
---------------------------------------------------------------------------------------------------------------------------------
计划通过热备的方式，把*.*.*.240上SGPMDB，复制到*.*.201.180上去,新库的SID为SGTESTB

首先在180上用oracle创建一样的目录，用来存放240的全库备份文件

创建一个密码文件
orapwd FILE=/oracle/base/product/10.2.0/db_1/dbs/orapwdSGTESTB PASSWORD=oracle ENTRIES=30

准备一个pfileSGTESTB.ora
DB_NAME=SGTESTB
db_block_size=8192
compatible=10.2.0.3.0
shared_pool_size=500M
db_file_name_convert=('/app/oracle/base/oradata/SGPMDB','/oracle/base/oradata/SGTESTB') ;
log_file_name_convert=('/app/oracle/base/admin/SGPMDB/arch','/oracle/base/admin/SGTESTB/arch') ;

在源库上执行
alter database begin backup;

select 'get '||substr(name,instr(name,'/',-1)+1),
'put '||name||' /oracle/base/oradata/SGTESTB/'||substr(name,instr(name,'/',-1)+1),bytes
from v$datafile;

alter database end backup;

通过在sqlplus上执行archive log list命令获取当前的日志顺序号，
从oldest online log sequence开始到current log sequence的联机redo日志应该是热备份的一部分。
SQL> archive log list ;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /app/oracle/base/admin/SGPMDB/arch
Oldest online log sequence     10131
Next log sequence to archive   10133
Current log sequence           10133

在sqlplus上执行 alter system switch logfile;     命令来强迫日志切换，以便所有的日志都被归档。

使用alter database backup controlfile to trace;命令获得控制文件的一个备份，
可以到%oracle_base%\admin\%oracle_sid%\udump目录中寻找最新的跟踪文件，其中有重建控制文件的全部命令。

alter database backup controlfile to trace resetlogs;

select value||'/'||
(select instance_name from v$instance)
||'_ora_'||spid||'.trc' from v$process,v$parameter where
name='user_dump_dest' and addr=(select paddr from v$session where sid=(select sid
from v$mystat where rownum=1));

获取trace文件查看控制文件创建信息     /app/oracle/base/admin/SGPMDB/udump/SGPMDB_ora_30797.trc

拷贝归档的日志文件到目标库相应目录。
select * from v$archived_log;
sgpmdb_10132_1_652109004.arch  sgpmdb_10133_1_652109004.arch

put /app/oracle/base/admin/SGPMDB/arch/sgpmdb_10132_1_652109004.arch /oracle/base/admin/SGTESTB/arch/sgpmdb_10132_1_652109004.arch
put /app/oracle/base/admin/SGPMDB/arch/sgpmdb_10133_1_652109004.arch /oracle/base/admin/SGTESTB/arch/sgpmdb_10133_1_652109004.arch

在目标库上启动辅助实例
export ORACLE_SID=SGTESTB
sqlplus / as sysdba
STARTUP NOMOUNT PFILE='/oracle/base/admin/SGTESTB/pfile/pfileSGTESTB.ora'

在控制文件备份中，有创建控制文件的脚本

在目标机上指明归档日志的位置
SQL> alter system set log_archive_dest='/oracle/base/admin/SGTESTB/arch' ;

登录RMAN，让RMAN识别到归档日志
RMAN> catalog start with '/oracle/base/admin/SGTESTB/arch';

RMAN> recover database;

没有更新的日志，到此就恢复完成，可以打开库了

重设日志打开
RMAN> alter database open resetlogs;

增加临时表空间
ALTER TABLESPACE TEMP ADD TEMPFILE '/oracle/base/oradata/SGTESTB/temp01.dbf'
     SIZE 50M  REUSE AUTOEXTEND ON NEXT 655360  MAXSIZE 32767M;

复制控制文件，并且在pfile里面指定
然后重新根据pfile生成spfile，并且修改/etc/oratab
