oracle数据库误修改/u01权限/所有者的故障恢复

有朋友找到我，说他对生产库做了误操作，导致数据库异常，请我帮忙处理,对/u01目录修改了用户和权限,导致数据库无法登录,但是业务还在继续

误操作命令

mkdir -p /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall /u01
mkdir -p /u01/app/oracle
chown oracle:oinstall /u01/app/oracle
chmod -R 775 /u01
尝试sqlplus登录数据库报ORA-12547

处理方法

root用户
chown -R oracle:oinstall /u01
chown oracle:oinstall /u01/app/oracle
 
oracle用户
chmod 6751 $ORACLE_HOME/bin/oracle
这里的修改权限,为了保证业务运行正常,是尽量往大的方向修改的,如果条件允许,在后期有条件的情况下,建议重新安装oracle软件
