pl/sql无法登录12c问题

 

1.问题1：ORA-28040: No matching authentication protocol

解决办法：在sqlnet.ora添加如下项

[oracle@localhost admin]$ vi sqlnet.ora     
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONsECT)
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/12.2.0.1/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8

SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8

 

2.问题2:明明账号密码是对的，但是提示：ORA-01017: invalid username/password; logon denied

解决办法：

重置下相关账号的密码

alter user hxl identified by oracle;
