ORA-12664: Services required by server not available on the client ORACLE 报错 故障修复 远程处理

文档解释

ORA-12664: Services required by server not available on the client

Cause: Service(s) that was (were) required by the server process were not available on the client process.

Action: Configure the client with the services required by the server (best solution) or delete the requirement from the configuration file of the server (least secure).

ORA-12664: Services required by server not available on the client 错误意味着客户端未设置要求的服务器选项。实际上，客户端未安装必要的组件或未更改合适的参数或系统环境。

官方解释

ORA-12664:“由服务器所需的服务未在客户端上可用”错误表明，尝试从客户端连接的TNS连接要求的服务未安装在客户端机器上。

常见案例

最常见的ORA-12664错误发生在从客户端尝试访问没有之前安装的服务器，而不是客户端的错误。

正常处理方法及步骤

1.检查要求的服务器功能是否在客户端机器上正确安装。

2.检查客户端机器上清单文件中定义的服务器参数和其他系统环境变量（如ORACLE_HOME、LD_LIBRARY_PATH等）是否正确设置，以确保正确安装服务器需求。

3.如果安装错误，请重新安装并更新客户端参数和环境变量。

按照上面的步骤处理，就可以避免ORA-12664错误。
