寫了一個指令碼來傳輸檔案，類似於這樣：

sendsystem(){
expect -c "
           spawn scp $ORACLE_BASE/oradata/$ORACLE_SID/system01.dbf oracle@$S_IP:$ORACLE_BASE/oradata/standby/
           expect {
               yes/no { send \"yes\r\"; exp_continue }
               *assword* { send \"oracle\r\" }
           };
           expect 100%
 

           expect eof ;
       "
}


sendsysaux(){
expect -c "
           spawn scp $ORACLE_BASE/oradata/$ORACLE_SID/sysaux01.dbf oracle@$S_IP:$ORACLE_BASE/oradata/standby/
           expect {
               yes/no { send \"yes\r\"; exp_continue }
               *assword* { send \"oracle\r\" }
           }
 
;
           expect 100%
           expect eof ;
       "
}

結果：

spawn scp /home/oracle/std_control01.ctl oracle@192.168.134.134:/oracle/oradata/standby/std_control01.ctl

system01.dbf沒傳完就不傳了
又試了幾次發現偶爾其他檔案也會傳不完就不傳了

最後發現是因為expect預設timeout為30S
手動新增set timeout -1設定超時時間為無窮大，問題解決

sendsystem(){
expect -c "
           set timeout -1
           spawn scp $ORACLE_BASE/oradata/$ORACLE_SID/system01.dbf oracle@$S_IP:$ORACLE_BASE/oradata/standby/
           expect {
               yes/no { send \"yes\r\"; exp_continue }
               *assword* { send \"oracle\r\" }
           };
           expect 100%
           expect eof ;
       "
}
