oracle开启远程访问

# 进入到listener.ora 和  tnsnames.ora 目录下
cd /home/oracle/app/oracle/product/11.2.0/dbhome_2/network/admin
# 开启监听器
vi listener.ora

# 配置vi tnsnames.ora

#登录oracle

sqlplus /nolog;
#使用sysdba来登录
conn /as sysdba;
# 查看是否开启了归档日志
# 如果返回 'ARCHIVELOG'，则进行用户授权步骤
# 如果返回 'NOARCHIVELOG'，则执行后续归档日志启用步骤
SELECT log_mode FROM v$database;

#开启归档日志

#关闭数据库
SQL> shutdown immediate;
#开启mount状态
SQL> startup mount;
# 开启归档日志，出现Database altered. 表示开启成功
SQL> alter database archivelog;
#查看归档状态
SQL> SELECT log_mode FROM v$database;
#打开数据库，一定要执行
SQL> alter database open;

效果图：


注意事项：

• 归档日志将占用大量的磁盘空间，如磁盘空间允许，则建议调大归档日志空间。

#设置归档日志目录和大小
