启动服务器上的所有oracle数据库

当服务器上有多台数据库时，如何管理：

思路通过 找文件"/bin/oracle" 确定oracle实例，列出本台服务器上所有的"/bin/oracle "文件，然后再根据此文件所有者（DB OWNER），通过sqlplus 脚本关闭和开起

以下是代码

#!/bin/bash
#+++++++++++++++++++++++++++++++++++++++++++++
# stop and start all oracle database in one server
#
# Param 1 : optional database owner 
# Param 2 : -stop |start
#+++++++++++++++++++++++++++++++++++++++++++++

  echo "   Database $oraid is going to stop"
  tmpfile=/tmp/"${oraid}"_start_db.$$.sql 
  echo "connect / as sysdba"  >  $tmpfile
  echo "                   "  >> $tmpfile
  echo "                  "   >> $tmpfile
  echo "shutdown immediate"   >> $tmpfile
  echo "exit"                 >> $tmpfile   
  chown $oraid:dba ${tmpfile}
  chmod 777 ${tmpfile}

  su - $oraid -c "sqlplus -s /NOLOG @$tmpfile" 0</dev/null | grep -v "ORA-01109"
  rm -f $tmpfile

  RC=$?;
  if [ $RC -eq 0 ]
    then 
      echo $(date) "DONE : STOP DB $oraid";
    else
      echo "=================================================================";
      echo

以下是执行效果：start  all db
