Oracle 11g ORA
环境描述： 1、oracle 11g R2 2、linux(centos6.2)服务器 3、client(win7-64bit) 4、刚刚在win7环境下安装好win64_oracle11gR2_client (下载地址：http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_client.zip) 操作： 1、打开终端 输入 sql
环境描述：
1、oracle 11g R2
2、linux(centos6.2)服务器
3、client(win7-64bit)
4、刚刚在win7环境下安装好win64_oracle11gR2_client (下载地址：http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_client.zip)
操作：
1、打开终端 输入 sqlplus system/oracle@chenhao01 (注意：chenhao01代表tnsnames.ora配置的名称。一下会贴出我的tnsnames.ora的文件代码)
(1、的操作出现一下错误:ORA-12154: TNS: could not resolve the connect identifier specified)
原因是：没有配置tns
2、找到 tnsnames.ora文件(我的这个文件是在 D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1\network\admin\sample目录下 注意：一般路劲
D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1 是在环境变量 path 中能找到的)
3、将tnsnames.ora备份一份打开tnsnames.ora将所有内容换成
chenhao01 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.126.129)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = chenhao)
)
)
(注意：这里的HOST、POST、SERViCE_NAME是我linux服务器中的，chenhao01 是和 在终端输入 sqlplus system/oracle@chenhao01 中的chenhao01是对应的)
4、配置好保存重新打开终端输入 sqlplus system/oracle@chenhao01 此时还会出现ORA-12154: TNS: could not resolve the connect identifier specified
原因是我将 tnsnames.ora文件放在了 D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1\network\admin\sample下
5、将配置好的tnsnames.ora文件放在 D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1\network\admin 下
6、再次重新打开终端输入 sqlplus system/oracle@chenhao01 (如果出现一下错误：ORA-12170 TNS 连接超时)
原因可能是：linux中的防火墙打开了 只需要将linux中的防火墙关闭 之后再win7 终端输入 sqlplus system/oracle@chenhao01
7、祝你成功，希望对你有帮助
