I cannot get export to run using a parfile. I've created 2 files

1. batch file
2. parfile

Batch file

rem echo on
rem cd\
rem c:

rem export does not work as a batch file with parfile still looking into this using second script in the meantime
rem exp userid=system/password parfile=u:\oracle\exports\fullexport.txt 1>>v:\backup\exports\fullexport.log
exp userid=system/password@evolvliv full=y grants=y rows=Y indexes=Y compress=Y constraints=Y file=u:\oracle\exports\evolvliv2.dmp


Parfile

FILE=evolvlivtest.dmp
FULL= Y
GRANTS = Y
INDEXES = Y
CONSTRAINTS=Y
ROWS = Y
COMPRESS = Y
LOG = V:\backup\exports\fullexport.log

It works fine when all parameters are specified on one line.
I'd also like the dmp file timestamped. Timestamping export file is more important to me than using the parfile. Any suggestions?
