今天遇到一个连接 192.168.56.102 这个库报错
Java.sql.SQLException: ORA-28040: No matching authentication protocol

Oracle 12C 下查询此报错
oralce:/oracle/db/app/12.1.0/db/network/admin> oerr ora 28040
28040, 0000, “No matching authentication protocol”
// *Cause: There was no acceptable authentication protocol for
// either client or server.
// *Action: The administrator should set the values of the
// SQLNET.ALLOWED_LOGON_VERSION_SERVER and
// SQLNET.ALLOWED_LOGON_VERSION_CLIENT parameters, on both the
// client and on the server, to values that match the minimum
// version software supported in the system.
// This error is also raised when the client is authenticating to
// a user account which was created without a verifier suitable for
// the client software version. In this situation, that account’s
// password must be reset, in order for the required verifier to
// be generated and allow authentication to proceed successfully.

Oracle 11g 下查询报错
oracle@oralce:/oracle/app/oracle/product/11.2.0/db/network/admin$ oerr ora 28040
28040, 0000, “No matching authentication protocol”
// *Cause: No acceptible authentication protocol for both client and server
// *Action: Administrator should set SQLNET_ALLOWED_LOGON_VERSION parameter
// on both client and servers to values that matches the minimum
// version supported in the system.

很明显，在 11G 和 12C 下的解决方案是不一样的。
在 11G 中的参数是 SQLNET_ALLOWED_LOGON_VERSION；
而在 12C 中的参数是 SQLNET.ALLOWED_LOGON_VERSION_SERVER 和 SQLNET.ALLOWED_LOGON_VERSION_CLIENT

因为我的环境是 12C 的，所以我使用 12C 的解决方式，设置以上 2 个参数。
因为我的环境上没有 sqlnet.ora 文件，所以新建了一个
vi sqlnet.ora
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8

然后重启监听
lsnrctl reload
