Batch file for Export Job

Question

Hi,
We created an OS batch file for our daily exports (backups). This file is scheduled to run daily at 7:00 P.M. A test run showed that it did not work. Can somebody find an error in the script?
rem ***** SAMPLE BATCH FILE TO DO DAILY EXPORT ******
@echo Export started at:
@echo
date /T
time /T
rem Here's a one-line NT command (But a long line!)
rem one that splits all the date parts out, outting
rem each one into it's own variable (weekday, day, month, year)
for /f "tokens=1-4 delims=/ " %%a in('date /t') do
(set=weekend=%%a& set day=%%b& set month=%%c& set year=%%d)
set logfile=%year%_%month%_%day%.log
set expfile=%year%_%month%_%day%.exp
set ORACLE_SID=BDC
set ORACLE_HOME=D:\oracle\product\10.2.0
exp system/bdcadmin@bdc full=y grants=y file=D:\export\bdc.dmp log=D:\export\bdc.log compress=N
@echo Export completed at:
@echo
date /T
time /T
rem ************* END OF BATCH FILE *********************
Thank you!

You can straight away use this batch file after modifying the exp line with your machine details and schema name.
@echo off
if %1/==:/ goto %2
if NOT %1/==/?/ goto Begin
for %%C in (echo. goto:End) do %%C
:Begin --------------------------------------------------------------
if NOT errorlevel 1 %0 : %OS%Parse MM DD
%0 : %OS%Parse DD MM
:Windows_NTParse ----------------------------------------------------
for /f "tokens=1-4 delims=/.- " %%A in ('date /t') do (
set Dow=%%A&set %3=%%B&set %4=%%C&set YYYY=%%D&goto End)
:Parse --------------------------------------------------------------
for %%C in (md cd) do %%C @tmp@
%COMSPEC% /e:2048 /c ~tmp1.bat > ~tmp2.bat
call ~tmp2
if NOT errorlevel 1 goto Slash
lfnfor on > "%_D%.-"
ren "%_D%.-" "??? ?? ?? ????"
for %%F in ("??? ?? ?? ????") do set _D=%%F
lfnfor off
:Slash
for %%S in ("%3=%%%4%%" "%4=%%YYYY%%" "YYYY=%%1") do echo set %%S>>~tmp1.bat
for %%S in (%_D%) do call ~tmp1 %%S
if errorlevel 1 goto Cleanup
%COMSPEC% /e:2048 /c ~tmp1.bat > ~tmp2.bat
call ~tmp2
:Cleanup
for %%C in ("set _D=" cd.. "deltree /y @tmp@ > NUL") do %%C
:End ----------------------------------------------------------------
