解决方案：

在oracle用户下修改$ORACLE_HOME/bin/oracle权限
[oracle@dba_oracle1 dbhome_1]$ pwd
/u01/app/oracle/product/12.2.0/dbhome_1
[oracle@dba_oracle1 dbhome_1]$ cd bin
[oracle@dba_oracle1 bin]$ pwd
/u01/app/oracle/product/12.2.0/dbhome_1/bin
[oracle@dba_oracle1 bin]$ chown -R oracle:asmadmin oracle

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

在修改文件属性
[oracle@dba_oracle1 ~]$ chmod 6751 $ORACLE_HOME/bin/oracle

[oracle@dba_oracle1 bin]$ls -la oracle
-rwsr-s--x 1 oracle asmadmin 239626641 Mar 3 2017 oracle

已完成

修改后之前发生的问题，得到解决，再也没出现其它问题。
