I am trying to use datapump to take a export of a schema(Meta_data only). However, I want the dump file to be named after the date & time of the export taken.
When i use the following command -- the job runs perfectly.
expdp system@***** dumpfile=expdp-`date '+%d%m%Y_%H%M%S'`.dmp directory=EXP_DP logfile=expdp-`date '+%d%m%Y_%H%M%S'`.log SCHEMAS=MARTMGR CONTENT=METADATA_ONLY
However, I want to run the export using an parfile. but if use the below parfile, i am encountering the following errors.
