duplicate 数据库 using backupset [oracle 11.2.0.3 + asm] => [oracle 11.2.0.3 + fs ]

参考 rhel64_11gr2_asm.txt 安装好另一台机器的rhel6.4，gi software，rdbms software。

vi /etc/hosts 
10.1.1.35 asmnode
10.1.1.36 asmnodedup

在asmnode 节点 查看initdbasm.ora 文件，确保target database 处于归档模式，否则duplicate 会报错 
[oracle@asmnode dbs]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dbs
[oracle@asmnode dbs]$ ls -l
total 28
-rw-rw---- 1 oracle asmadmin 1544 Apr 25 21:49 hc_dbasm.dat
-rw-r----- 1  oracle  oinstall            40 Apr 25 21:49 initdbasm.ora
-rw-r--r-- 1  oracle  oinstall       2851 May 15  2009 init.ora
-rw-r----- 1  oracle  asmadmin     24 Apr 25 21:06  lkDBASM
-rw-r----- 1  oracle  oinstall       1536 Apr 25 21:06 orapwdbasm
[oracle@asmnode dbs]$ cat initdbasm.ora 
SPFILE='+DG_DATA/dbasm/spfiledbasm.ora'


在asmnode 节点 用oracle 用户创建 参数文件 abc.ora 文件
[oracle@asmnode dbs]$ sqlplus / as sysdba;
sql> create pfile='?/dbs/abc.ora' from memory;

在asmnode 节点 用oracle 用户创建备份集

备份数据库及控制文件及归档文件，plus archivelog 紧接着不能是 all
run {
 allocate channel ch00 device type disk;
 sql 'alter system checkpoint';
 backup as compressed backupset database 
 include current controlfile format '/u01/backup/DB_%T_%U' 
  plus archivelog delete all input format '/u01/backup/ARCH_%T_%U';
 release channel ch00;
}

单纯归档备份， archivelog 必须紧接着 all 
run {
 allocate channel ch00 device type disk;
 sql 'alter system checkpoint';
  backup as compressed backupset archivelog all delete all input format '/u01/backup/arch_%T_%U';
 release channel ch00;
}

备份过程中均有备份集的存放路径输出

查看备份集
[oracle@asmnode backup]$ cd /u01/backup/
[oracle@asmnode backup]$ ls -l
total 251104
-rw-r----- 1 oracle asmadmin     42496 May 11 16:48 ARCH_20160511_24r5b7av_1_1
-rw-r----- 1 oracle asmadmin               2560 May 11 16:49 ARCH_20160511_27r5b7cq_1_1
-rw-r----- 1 oracle asmadmin   255967232 May 11 16:49 DB_20160511_25r5b7b1_1_1
-rw-r----- 1 oracle asmadmin      1114112 May 11 16:49 DB_20160511_26r5b7co_1_1

把备份集拷贝到asmnodedup 节点的相同路径下，如果不是相同路径下，可通过ln -s 来解决
[oracle@asmnode backup]$ scp /u01/backup/ARCH* [email protected]:/u01/backup/
[oracle@asmnode backup]$ scp /u01/backup/DB* [email protected]:/u01/backup/

在 asmnodedup 节点 创建pfile参数文件
export ORACLE_SID = dbasmd
[grid@asmnodedup dbs]$ vi /u01/app/grid/product/11.2.0/grid_1/dbs/initdbasmd.ora

*.audit_file_dest='/u01/app/oracle/admin/dbasmd/adump'
*.audit_trail='DB'
*.compatible='11.2.0.0.0'
*.control_files='/u01/app/oracle/oradata/dbasmd/current.260.911598793'#Set by RMAN
*.core_dump_dest='/u01/app/oracle/diag/rdbms/dbasmd/dbasmd/cdump'
*.db_block_size=8192
*.db_domain=''
*.db_name='DBASMD'#Reset to original value by RMAN
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=dbasmXDB)'
*.log_buffer=7020544# log buffer update
*.memory_target=1536M
*.open_cursors=300
*.optimizer_dynamic_sampling=2
*.optimizer_mode='ALL_ROWS'
*.plsql_warnings='DISABLE:ALL'# PL/SQL warnings at init.ora
*.processes=300
*.query_rewrite_enabled='TRUE'
*.remote_login_passwordfile='EXCLUSIVE'
*.resource_manager_plan=''
*.result_cache_max_size=3936K
*.sessions=472
*.skip_unusable_indexes=TRUE
*.undo_tablespace='UNDOTBS1'
#*.db_create_file_dest='/u01/app/oracle/oradata/dbasmd/'
*.db_file_name_convert=('+DG_DATA/dbasm/','/u01/app/oracle/oradata/dbasmd/')
*.log_file_name_convert=('+DG_DATA/dbasm/','/u01/app/oracle/oradata/dbasmd/')

需要修改db_file_name_convert，log_file_name_convert
或者直接设定 db_create_file_dest

在 asmnodedup 节点 创建必要的目录
mkdir -p /u01/app/oracle/admin/dbasmd/adump
mkdir -p /u01/app/oracle/diag/rdbms/dbasmd/dbasmd/trace
mkdir -p /u01/app/oracle/diag/rdbms/dbasmd/dbasmd/cdump
mkdir -p /u01/app/oracle/oradata/dbasmd/{controlfile,datafile,tempfile,onlinelog}

需要保证target和auxiliary 库的sys用户口令相同。
从asmnode 拷贝原数据库的密码文件到 asmnodedup 节点 oracle 用户 $ORACLE_HOME/dbs 目录下，然后重命名
[oracle@asmnode dbs]$ scp /u01/app/oracle/product/11.2.0/db_1/dbs/orapwdbasm [email protected]:/u01/app/oracle/product/11.2.0/db_1/dbs 
[oracle@asmnodedup dbs]$ mv orapwdbasm orapwdbasmd

或者在 asmnodedup 使用 orapwd 创建一个和target database 的sys一样密码的密码文件。

在 asmnodedup 节点 grid 用户 用asmcd 查看一下
[grid@asmnodedup bin]$ ./asmcmd
ASMCMD> ls -l
State    Type    Rebal  Name
MOUNTED  EXTERN  N      DG_DATA/

静态监听，两个节点都要添加
在 asmnode 节点  grid 用户下添加 静态监听
[grid@asmnodedup admin]$ vi /u01/app/grid/product/11.2.0/grid_1/network/admin/listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
       (SID_DESC =
          (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
          (SID_NAME =dbasm)
        )
  )

在 asmnodedup 节点  grid 用户下添加 静态监听
[grid@asmnodedup admin]$ vi /u01/app/grid/product/11.2.0/grid_1/network/admin/listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
        (SID_DESC =
           (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
           (SID_NAME =dbasmd)
         )
  )

在 asmnode， asmnodedup 节点 重启监听，看如输出状态为 UNKNOWN 就表示静态监听已添加成功  
[grid@asmnodedup admin]$ lsnrctl stop
[grid@asmnodedup admin]$ lsnrctl start
Services Summary...
Service "dbasmd" has 1 instance(s).
  Instance "dbasmd", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
  
在 asmnode，asmnodedup 节点, oracle 用户下 添加 tnsnames.ora 文件
tns_dbasm =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = asmnode)(PORT = 1521))
    (CONNECT_DATA =
       (SERVER = DEDICATED)
       (SERVICE_NAME = dbasm)
    )
   )

tns_dbasmd =                 
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = asmnodedup)(PORT = 1521))
    (CONNECT_DATA =
       (SERVER = DEDICATED)
       (SERVICE_NAME = dbasmd)
    )
)  

在 asmnodedup 节点 oracle 用户
