Server Utilities :: EXP Versus IMPDP Interrogating Dump File

I have a bit of an issue with Oracle datapump dump files.

Today, I manage the export and import of oracle dump files. As part of the batch export process I have a script which essentially says:

For each schema realated to my application in THIS instance, export schema via the system user (system user allows me privs to all schemas).

On the import UI side of things I am able to run a "head -20" command on the dmp file and determine the "export client version", "date the schema was dumped", and "what schema it was dumped from". All useful info presented in my UI.

Sample output: Begin

EXPORT:V09.02.00
DSYSTEM
RUSERS
8192
Wed Jun 30 11:51:21 UserXXX.dmp
#C##
#C##

[code]....

Sample output: End

in that I allow the importation of production schemas into test schemas, (contained in a different tablespace). Based on naming convention I can determine the schema type (production or test). Additionally and probably most importantly, I am assured where the data has come from.

In looking at "expdp" and the dump file. Using the same method as above, it appears the data pump dump DOES NOT carry similar headers. Because of this, I am unable to return very little useful info from the dump file.

I realize I could run the impdp with the "sqlfile=myfile.sql" and then interrogate the sql file for the info. But on large dump files this would be fairly time consuming compared to a "head -20" on a dump file.
