Linux下的flashback脚本

一个客户比较关心逻辑错误的恢复，我们给他推荐的方案是在容灾库上使用flashback技术，下面是一个简单的Linux的脚本。

#!/bin/bash

export LOGIN_USER=test
export LOGIN_PWD=test

flashscn()
{
echo -e "enter scn:\c"
read SCNNUM
STR1="flashback table $OWNER.$TABLE_NAME to scn $SCNNUM;"
echo $STR1
T1=`sqlplus -silent $LOGIN_USER/$LOGIN_USER <<EOF
set pagesize 0 feedback off verify off heading off echo off
alter table $OWNER.$TABLE_NAME enable row movement;
$STR1
alter table $OWNER.$TABLE_NAME disable row movement;
EOF`
if [ -z "$T1" ];then
echo "######"
echo "flashback table $TABLE_NAME OK!"
else
echo "######"
echo "flashback tabel $TABLE_NAME error:"
echo $T1 |awk -F "ORA-" '{print "ORA-" $NF}'
fi
}

flashtime()
{
echo -e "enter time (example 2014-05-18 20:34:21):\c"
read STIME
STR2="flashback table $OWNER.$TABLE_NAME to timestamp to_timestamp('$STIME','yyyy-mm-dd hh24:mi:ss');"

else
echo "######"
echo "flashback tabel $TABLE_NAME error:"
echo $T2 |awk -F "ORA-" '{print "ORA-" $NF}'
