手把手教你如何搭建Oracle的exp备份机

11/19/2009来源:Oracle教程人气:2416

Oracle服务端装的版本为10.1,ip地址为129.1.9.90
  在备份机上安装oracle10.1,配IP地址为129.1.9.91,关闭防火墙。
  并修改tnsnames.ora文件,添加如下内容:
  JMYBJS =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 129.1.9.90)(PORT = 1521))
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = jmybjs)
  )
  )
  在D盘新建文件夹:
  d:\backup\dmp
  d:\backup\log
  用来存放dmp文件和备份的日志。
  修改备份脚本如下:
  'Nightly Bulk copy export for the customers table&veiw
  'Write output to clarentYYMMDD.txt and errors to ERRYYMMDD.txt
  ''strssql="bcp demo.clrnuser.bill_recordview out c:\bibak\"+outfile+" -U jl_voip -P jlvoip -c -k -t,"
  Dim outfile,aa,bb,stroption1,stroption2,A,B,C,strsql
  set ws=WScript.CreateObject("WScript.shell")
  A=cint(month(dateadd("d",0,date())))
  B=cint(day(dateadd("d",0,date())))
  C=cint(year(dateadd("d",0,date())))
  if A<10 then aa=cstr(0)+cstr(A)
  if A>=10 then aa=cstr(A)
  if B<10 then bb=cstr(0)+cstr(B)
  if B>=10 then bb=cstr(B)
  outfile=cstr(C)+aa+bb
  stroption1="D:\oracle_bf\product\10.1.0\Db_1\BIN\exp system/******@jmybjs full=y buffer=900000 file=d:\backup\dmp\jmybjs"+outfile+" log=d:\backup\log\jmybjs"+outfile+".log"""
  strsql=stroption1
  ret=ws.Run(strsql)
  测试后,备份正常。
  修改删除脚本,使备份数据在备份机上保留30天
  'Nightly Bulk copy export for the customers table&veiw
  'Write output to clarentYYMMDD.txt and errors to ERRYYMMDD.txt
  ''strssql="bcp demo.clrnuser.bill_recordview out c:\bibak\"+outfile+" -U jl_voip -P jlvoip -c -k -t,"
  Dim outfile,aa,bb,stroption1,stroption2,A,B,C,strsql
  set ws=WScript.CreateObject("WScript.shell")
  A=cint(month(dateadd("d",-30,date())))
  B=cint(day(dateadd("d",-30,date())))
  C=cint(year(dateadd("d",-30,date())))
  if A<10 then aa=cstr(0)+cstr(A)
  if A>=10 then aa=cstr(A)
  if B<10 then bb=cstr(0)+cstr(B)
  if B>=10 then bb=cstr(B)
  outfile=cstr(C)+aa+bb
  stroption1="C:\WINDOWS\system32\Delete d:\backup\dmp\jmybjs"+outfile+".dmp"
  strsql=stroption1
  ret=ws.Run(strsql)
  测试,提示不正确,检查后,发现这个备份机中的sytem32文件夹下没有delete.exe文件,从其他系统中拷贝delete.exe文件到这个备份机的system32下,测试正常。
  最后,添加到windows的定时任务中。
