关于navicat连接oracle 报 ORA-12737 set CHS16GBK错误的解决

1、原因：
ORA-12737: Instant Client Light: unsupported server character set CHS16GBK 
Google，解释如下：
ORA-12737:
Instant Client Light: unsupported server character set string
Cause:     The character set specified is not allowed for this operation or is invalid. Instant Client Light has only minimal character sets.
Action:     Do not use Instant Client Light for this character set


2、首先，我们打开“tools”-->"options"菜单，见到如下界面，依据OCI library(oci.dll) 路径，导航到 navicat oci 目录下，备份里面的文件（通过在该目录新建bak文件夹，将“%dir%/Navicat Lite\instantclient_10_2”路径下的所有dll文件剪切到bak文件夹）。



3、在oracle 客户端安装目录bin/目录下，找到如下几个.dll文件
4、将上面所列文件放置到“%dir%/Navicat Lite\instantclient_10_2” 目录下，重新启动navcat即可。
