Executing the Purge Script through command line(datacleanup.bat/sh) will throw an error "The system cannot find the file .\common.out.and Could Not Find C:\MDM\MDM920_Oracle\MDM\mdm\9.2\bin\common.out"
But issue will not be same i.e Exception and caused by is different

Example -
1.C:\MDM\MDM920_Oracle\MDM\mdm\9.2\bin>datacleanup.bat -o repository -rn RepTEST -an TESTD -mn TESTD -pwd TESTD
