[20180211]关于oracle执行文件权限问题.txt
--//如果oracle用户一般建立2个用户组.一般oinstall,dba组.缺省指定组oinstall
--//如果数据库在运行时修改oracle执行文件权限,会到处一些进程出现问题.测试如下:
1.环境:
$ id
uid=502(oracle) gid=502(oinstall) groups=502(oinstall),503(dba)
--//修改权限
$ ls -l $ORACLE_HOME/bin/oracle
-rwsr-s--- 1 oracle oinstall 239627073 2015-08-17 15:58:55 /u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle
$ chgrp dba $ORACLE_HOME/bin/oracle
$ ls -l $ORACLE_HOME/bin/oracle
-rwxr-x--- 1 oracle dba 239627073 2015-08-17 15:58:55 /u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle
$chmod 6750 $ORACLE_HOME/bin/oracle
2.检查alert.log
--//alert*.log,后台出现大量错误.

--//注意下划线提示,修改回来:
$ chgrp oinstall $ORACLE_HOME/bin/oracle
$ ls -l $ORACLE_HOME/bin/oracle
-rwxr-x--- 1 oracle oinstall 239627073 2015-08-17 15:58:55 /u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle
$ chmod 6750 $ORACLE_HOME/bin/oracle
--//问题消失.
--//单机环境一般不会出现,如果在rac环境,建立多个实例通过dbca配置,要有1个执行用户管理组配置的过程,如果与前面不同,就会出现问题.
