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)
