REM obtains the current system time. The value may vary depending on the operating system.
Set CURDATE = % date :~ 0, 4% % date :~ 5, 2% % date :~ 8, 2%
Set CURTIME = % time :~ 0, 2%
If the REM hours are less than 10, add 0 before
If "% CURTIME %" = "0" set CURTIME = 00
If "% CURTIME %" = "1" set CURTIME = 01
If "% CURTIME %" = "2" set CURTIME = 02
If "% CURTIME %" = "3" set CURTIME = 03
If "% CURTIME %" = "4" set CURTIME = 04
If "% CURTIME %" = "5" set CURTIME = 05
If "% CURTIME %" = "6" set CURTIME = 06
If "% CURTIME %" = "7" set CURTIME = 07
If "% CURTIME %" = "8" set CURTIME = 08
If "% CURTIME %" = "9" set CURTIME = 09
Set CURTIME = % CURTIME % time :~ 3,2% % time :~ 6, 2%
REM sets the owner, user name, and password
Set OWNER = owner
Set USER = user
Set PASSWORD = pwd
REM creates a backup directory with the directory structure of backup/YYYYMMDD/
If not exist "oracle_backup" mkdir oracle_backup
If not exist "oracle_backup \ % CURDATE %" mkdir oracle_backup \ % CURDATE %
Set CURDIR = oracle_backup \ % CURDATE %
Set FILENAME = % CURDIR % \ % OWNER % _ % CURDATE % _ % CURTIME %. dmp
Set EXPLOG = % CURDIR % \ % OWNER % _ % CURDATE % _ % CURTIME % _ log. log
REM calls the ORACLE exp command to export user data
Exp % USER %/% PASSWORD % @ sid log = % EXPLOG % file = % FILENAME % owner = (% OWNER %)
