Oracel增加IP白名单限制

F:\Java\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\sqlnet.ora

修改sqlnet.ora文件增加两行

# like12 add,20231025,IP白名单限制
TCP.VALIDNODE_CHECKING=yes
TCP.INVITED_NODES=(WIN-I4HJRGH080V,127.0.0.1,xxx.xxx.xxx.xxx)

注意：需要将计算机名hostname添加进去 否则本机PL/SQL工具连接不了 

完整示例为：

# sqlnet.ora Network Configuration File: F:\Java\Oracle\product\11.2.0\dbhome_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
 
# This file is actually generated by netca. But if customers choose to 
# install "Software Only", this file wont exist and without the native 
# authentication, they will not be able to connect to the database on NT.
 
SQLNET.AUTHENTICATION_SERVICES= (NTS)
 
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
 
# like12 add,20231025,IP白名单限制
TCP.VALIDNODE_CHECKING=yes
TCP.INVITED_NODES=(WIN-I4HJRGH080V,127.0.0.1,58.42.241.105)

可能不需要的操作：

修改listener.ora文件 增加一段

    # like12 add,20231025,IP白名单限制

      (GLOBAL_NAME = orcl)
      (ORACLE_HOME = F:\Java\Oracle\product\11.2.0\dbhome_1)
      (SID_NAME = orcl)
    )
