Oracle10g客户端工具plsql链接服务端配置


Oracle10g客户端工具比如plsql,在网络中链接服务端问题比较多,经常出现很多莫名其妙的问题。实际上不是plsql的配置,问题还是出在客户端配置上面,网上有很多的解决办法,并非真正的凑效,下面说一下有效的解决办法:


安装客户端为企业管理器,默认方式安装吧。


安装后需要配置,这个位置位置在:D:\oracle\product\10.2.0\client_1\NETWORK\ADMIN


有两个文件需要配置:

sqlnet.ora

tnsnames.ora


先看tns:

# tnsnames.ora Network Configuration File: d:\oracle\product\10.2.0\client_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.


EXTPROC_CONNECTION_DATA =

 (DESCRIPTION =

   (ADDRESS_LIST =

     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

   )

   (CONNECT_DATA =

     (SID = PLSExtProc)

     (PRESENTATION = RO)

   )

 )


KFCS =

 (DESCRIPTION =

   (ADDRESS_LIST =

     (ADDRESS = (PROTOCOL = TCP)(HOST = 10.87.30.44)(PORT = 1521))

     (ADDRESS = (PROTOCOL = TCP)(HOST = 10.87.30.45)(PORT = 1521))

     (ADDRESS = (PROTOCOL = TCP)(HOST = 10.87.30.46)(PORT = 1521))

     (ADDRESS = (PROTOCOL = TCP)(HOST = 10.87.30.47)(PORT = 1521))

   )

   (CONNECT_DATA =

     (SERVER = DEDICATED)

     (SERVICE_NAME = KFCS)

   )

 )


红色部分为服务器端配置的tns,服务名为KFCS


这下注意了,还有个网络服务文件也需要配置:

# sqlnet.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora

# Generated by Oracle configuration tools.


# This file is actually generated by netca. But if customers choose to

# install "Software Only", this file wont exist and without the native

# authentication, they will not be able to connect to the database on NT.


SQLNET.AUTHENTICATION_SERVICES= (KFCS)


NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

上面的红色服务名要和tns文件中的配置保持一致,否则会有问题。(默认的不对)


默认安装客户端的时候不对。


只要有了这两项配置,,你就可以正确的通过plsql链接数据库了。


-----------------------------------------------------------

特别说明下:通过sqlplus命令行链接数据库可能和这个配置无关,具体我试过,感觉sqlplus可以链接成功,就是plsql不成功。感觉sqlplus链接的方式可能不一样。
