@H_502_8@@H_502_8@

但是业务还在继续，没有受到影响。同时，在oracle用户下查看$ORACLE_HOME/bin/oracle文件权限：
-rwxr-x--x 1 oracle oinstall 239626641 Mar 3 2017 oracle@H_502_8@

解决方案：@H_502_8@

在oracle用户下修改$ORACLE_HOME/bin/oracle权限
[[email protected]_oracle1 dbhome_1]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1
[[email protected]_oracle1 dbhome_1]$ cd bin
[[email protected]_oracle1 bin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/bin
[[email protected]_oracle1 bin]$ chown -R oracle:asmadmin oracle@H_502_8@

修改后
-rwxr-x--x 1 oracle asmadmin 239626641 Mar 3 2017 oracle@H_502_8@

在修改文件属性
[[email protected]_oracle1 ~]$ chmod 6751 $ORACLE_HOME/bin/oracle@H_502_8@

[[email protected]_oracle1 bin]$ls -la oracle
-rwsr-s--x 1 oracle asmadmin 239626641 Mar 3 2017 oracle@H_502_8@

已完成@H_502_8@

修改后之前发生的问题，得到解决，再也没出现其它问题。@H_502_8@
