AIX 配置vncserver
主机环境:
WINDOWS 2008 X64+ORACLE 11G R2 x64+CYGWIN
初始安装时报以下错误:
经检查ORACLE 11G x64没有lib32目录,将ORACLE 11G 32bit的lib目录拷贝至ORACLE 11G x64的ORACLE_HOME下,取名为lib32,同时设置环境变量,再次安装时报如下错误
安装win32_11gR2_client.zip,同时修改环境变量,ORACLE_HOME。LD_LIBARAY_PATH。报如下错误:
将ORACLE 11G WIN32的OCI目录下面的子目录拷贝至/cygdrive/c/app/Administrator/product/11.2.0/client_1/sdk下安装成功
运行require,报错
可以看到ruby-oci8已经成功安装
将/cygdrive/c/app/Administrator/product/11.2.0/client_1/的oci.dll拷贝至tmp目录,环境变量恢复ORACLE 11G X64,在PATH前面加上/tmp,再次require
如果直接替换64位的oci.dll,会报如下错误
WINDOWS 2008 X64+ORACLE 11G R2 x64+CYGWIN
