虚拟机服务器重启, oracle11g 的启动和plsql的连接

oracle11G  部署在 虚拟机windows server 2008上,虚拟机重启后无法重启数据库实例

1.未安装客户端 使用instantclient-basic-nt-11.2.0.3.0.zip  配置plsql连接

http://download.oracle.com/otn/nt/instantclient/112030/instantclient-basic-nt-11.2.0.3.0.zip

虚拟机重启之后oracle实例无法启动

  1>.tnsnames.ora文件里添加
LISTENER_ORCL =(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

在命令提示符中  :sqlplus / as sysdba;
提示成功连接到空闲连接后：  startup      启动数据库实例

  2>.需要在listener.ora中添加监听配置

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_2)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_2\bin\oraclr11.dll")
    )
  )

添加

(SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = C:\instantclient_11_2)
      (SID_NAME = ORCL)
    )

添加之后为:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_2)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_2\bin\oraclr11.dll")
    )

(SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = C:\instantclient_11_2)
      (SID_NAME = ORCL)
    )
  )

这样本地的plsql就可以成功连接了。
远程连接需要在未安装客户通通过上面的下载配置plsql连接的NETWORK\ADMIN下copy放置一个sqlnet.ora文件，增加

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

配置后为：

SQLNET.AUTHENTICATION_SERVICES = (NTS) 

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
