Normally when you export a database dump, and provide it to any body (without the export logs), its and R&D task to figure out the source of the database version that generated this dump which is a tedious job and how was the dump generated (exp or expdp...etc).
i am proposing that Oracle can develop a tool so DBA's can use to fetch generic information about the dump being exported such as: Database Version, Dump File version, export utility used, schema(s) name within the dump, export command used,....etc.
There is currently many workaround for this problem, scripts provided by Oracle Support and customized scripts by DBA's contribution in some blogs. However, i think its time that we have such utility that will make our lives easier to extract the header information of the DUMP.
