Windows 64位下装Oracle 11g 64位,PLSQL Developer使用出现以下问题:
1、Database下拉框为空:

2、强制输入用户名、密码及Database,登录弹出:
Initialzation error Could not initialize "...." Make sure you have the 32 bits Oracle Client installed. OracleHomeKey: OracleHomeDir:... Found:oci.dll Using: ... Loadlibrary(...) returned 0

说明PLSQL Developer并不支持Oracle 64位客户端连接。
解决办法:
1、下载32位Oracle客户端
其实可以下载免安装版的,http://www.oracle.com/technetwork/topics/winsoft-085727.html,我下载的是instantclient-basic-nt-11.2.0.2.0.zip。
2、解压
解压instantclient-basic-nt-11.2.0.2.0.zip,例如到D:\instantclient_11_2
3、设置PLSQL Developer
启动PLSQL Developer,不登录点取消进入PLSQL Developer,Tools->>Preferences:
Oracle Home:OraDb11g_home1(发现这里似乎可以随便写,我填的是安装的Oracle 11g 64位的)
OCI Library:D:\instantclient_11_2\oci.dll

4、添加环境变量
TNS_ADMIN ->> D:\app\YangJin\product\11.2.0\dbhome_1\NETWORK\ADMIN
中文乱码问题:
启动PLSQL Developer,登录发现中文表名乱码:

解决方法:
添加环境变量:NLS_LANG ->> AMERICAN_AMERICA.UTF8 |
