自己封裝的一個shell指令碼，關鍵是如何呼叫呢？求助！

#!/bin/sh 
function createOracleInstance(){
    tableSpace=$1
    tempTableSpace=${tableSpace}"_temp"
    dataTableSpace=${tableSpace}"_data"
    user=$2
    pwd=$3

    #臨時表空間
    create temporary tablespace ${tempTableSpace}
    tempfile '/u01/datas/${tempTableSpace}.dbf'
 

    size 50m
    autoextend on
    next 50m maxsize 20480m
    extent management local;

    #建立資料表空間
    create tablespace ${dataTableSpace}
    logging
    datafile '/u01/datas/${dataTableSpace}.dbf'
    size 50m
    autoextend on
    next 50m maxsize 20480m
    extent management local;

    #建立使用者
    create
 
 user ${user}
      identified by "${pwd}"
      default tablespace ${dataTableSpace}
      temporary tablespace ${tempTableSpace}
      profile DEFAULT;
    grant connect to ${user};
    grant dba to ${user};
    grant exp_full_database to ${user};
    grant imp_full_database to ${user};
    grant resource to
 
 ${user};
    grant unlimited tablespace to ${user};
    echo "臨時表空間名為${tempTableSpace},資料表空間為 ${dataTableSpace},使用者名稱：${user},密碼：${pwd}"
}
sqlplus / as sysdba
createOracleInstance $1 $2 $3

因為有sqlplus / as sysdba等命令，後面呼叫語句被中斷了，是不是有新視窗進入導致的，如果去掉sqlplus / as sysdba，手工執行該命令後進入sql命令列，又該如何呼叫Shell指令碼呢？
