每次安装Oracle以后,都会出现使用plsql连接不上的问题!多次重启电脑、重装系统的磨人经历之后,
有木有想说句 TMD 平复一下心情?
先别骂!今天看到这篇文章算是你我之幸!希望能帮助广大技术人员减少一些时间,顺利进行连接!
注:也可以用plsql连接远程数据库(只要有oracle的network\admin\tnsnames.ora就行)。
首先下载64位oracle以及32位轻量级客户端(注意版本的对应,我用的是11g的oracle和11.2的客户端):
以下步骤请自行更改路径,不然,出错了别怪我哦:
oracle安装到某路径下,安装步骤很简单,网上可以搜到!
客户端随便解压到一个路径,我的是放在D:\app\shuhao\instantclient_11_2了。
然后把oracle中的D:\app\shuhao\product\11.2.0\dbhome_1里面的整个network文件夹复制,
粘贴到客户端文件夹D:\app\shuhao\instantclient_11_2下面,如下图所示:
D:\app\shuhao\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora文件内容,添加一个SID_DESC:
- # listener.ora Network Configuration File: D:\app\shuhao\product\11.2.0\dbhome_1\network\admin\listener.ora
- # Generated by Oracle configuration tools.
-
- SID_LIST_LISTENER =
- (SID_LIST =
- (SID_DESC =
- (SID_NAME = CLRExtProc)
- (ORACLE_HOME = D:\app\shuhao\product\11.2.0\dbhome_1)
- (PROGRAM = extproc)
- (ENVS = "EXTPROC_DLLS=ONLY:D:\app\shuhao\product\11.2.0\dbhome_1\bin\oraclr11.dll")
- )
- #下面的SID_DESC是新增加的内容,注意修改ORACLE_HOME路径
- (SID_DESC =
- (SID_NAME = orcl)
- (ORACLE_HOME = D:\app\shuhao\product\11.2.0\dbhome_1)
- (GLOBAL_DBNAME = orcl)
- )
- )
-
- LISTENER =
- (DESCRIPTION_LIST =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
- )
- )
-
- ADR_BASE_LISTENER = D:\app\shuhao
D:\app\shuhao\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora文件内容,源文件没有做改动:
- # tnsnames.ora Network Configuration File: D:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
- # Generated by Oracle configuration tools.
-
- ORACLR_CONNECTION_DATA =
- (DESCRIPTION =
- (ADDRESS_LIST =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
- )
- (CONNECT_DATA =
- (SERVICE_NAME = orcl)
- )
- )
-
- LISTENER_ORCL =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
- ORCL =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
- (CONNECT_DATA =
- (SERVER = DEDICATED)
- (SERVICE_NAME = orcl)
- )
- )
D:\app\shuhao\instantclient_11_2\network\admin\tnsnames.ora文件内容:
- # tnsnames.ora Network Configuration File: D:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
- # Generated by Oracle configuration tools.
-
- ORACLR_CONNECTION_DATA =
- (DESCRIPTION =
- (ADDRESS_LIST =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
- )
- (CONNECT_DATA =
- (SERVICE_NAME = orcl)
- )
- )
-
- LISTENER_ORCL =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
- ORCL =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
- (CONNECT_DATA =
- (SERVER = DEDICATED)
- (SERVICE_NAME = orcl)
- )
- )
- #新增 @ 标识符,用于区分本地与远程oracle
- ORCL@192.168.0.164 =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.164)(PORT = 1521))
- (CONNECT_DATA =
- (SERVER = DEDICATED)
- (SERVICE_NAME = orcl)
- )
- )
不登录plsql,直接按Cancel,进入后在Tools--->Preferences---->Connection中配置OCI为32位客户端的OCI
D:\app\shuhao\instantclient_11_2\oci.dll
添加前2个系统变量:
1. 变量名:TNS_ADMIN
变量值:D:\app\shuhao\instantclient_11_2\network\admin
2. 变量名:NLS_LANG
变量值:SIMPLIFIED CHINESE_CHINA.ZHS16GBK
3. Path中配置加入:
D:\app\shuhao\product\11.2.0\dbhome_1\BIN;D:\app\shuhao\instantclient_11_2;
启动oracle服务与监听,这个就不需要描述了。
当看到Database下拉框中有本地的ORCL以及远程的ORCL@192.168.0.164就算成功了!!!
