The option 1 is the fastest option and easiest way to code in unix.
>>Wondering is there any technique to validate RECORD COUNTS between Data Pump Export vs Import, when using only DATA_ONLY export option.
there is no need to do all the Process, Just look for Error in export/import Log file.. if You do not get any error means your counts are fine..this is enough to validate the record.
Thanks DK2010. That will eliminate record count. My script is scanning for any error on both Log files. Very helpful
