ttrestore使用说明

E:\>ttrestore -h
Usage:
  ttrestore [-h | -help | -?]
  ttrestore [-V | -version]
  ttrestore [-fname <filePrefix>] [-noconn] -dir <directory>
                 {<DSN> | [-connstr] <connStr>}
  ttrestore -i [-noconn] {<DSN> | [-connstr] <connStr>}

options:
  -h | -help | -?      Prints this message and exits.
  -V | -version        Prints the release number and exits.
  -fname <filePrefix>  The file prefix for the backup files in the backup
                       directory. Default is the base filename portion of the
                       DataStore parameter of the data store to be restored.
  -dir <directory>     The directory in which the backup files are stored.
  -noconn              Do not test-connect after restoring the data store.
  -i                   Read from standard input for stream data.
  <DSN>, <connStr>     The DSN or ODBC connection string of the data store
                       to be restored.

补充说明
1)ttRestore 除了可以作为数据库还原操作外，还可以用来做数据库复制

ttBackup -dir /users/rob/tmp -fname restored "dsn=origDSN"
ttRestore -dir /users/rob/tmp -fname restored "dsn=restoredDSN"

2)对于在Linux或者unix系统使用streamFull备份恢复方式

dd bs=64k if=/dev/rmt0 | ttRestore -i DSN=FastIns

3)该命令是用来数据库还原，那么对于备份之后到数据库异常这段时间的数据该如何处理，是否会丢失暂时还未知。

一、动态监听
1.监听文件

[oracle@node1 admin]$ more /u01/oracle/network/admin/listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/oracle)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

2.监听状态

3.客户端tns文件[有部分测试加上了(UR=A)]

vm_asm =
  (DESCRIPTION =

    (CONNECT_DATA =
      (SERVICE_NAME = +ASM)

      (UR=A)  #分存在和不存在测试
    )
  )

二、静态监听
1.监听文件

[oracle@node1 admin]$ more listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =  
     (GLOBAL_DBNAME = chf)
     (ORACLE_HOME = /u01/oracle)
     (SID_NAME = chf)
    )
    (SID_DESC =
     (GLOBAL_DBNAME = +ASM)
     (ORACLE_HOME = /u01/oracle)

     )
  )

4.含(UR=A)测试

5.easy connect访问asm实例

SQL> select instance_name from v$instance;

INSTANCE_NAME
--------------------------------
+ASM

三、总结
1.在动态监听中，只有设置了(UR=A)才能够远程访问ASM实例；
2.在静态监听中，无论是否设置(UR=A)均可远程访问ASM实例，甚至可以使用easy connect方法方法ASM实例。
