schema compare using EXPDP : any pitfalls ?

tadimetiMay 6 2015 — edited May 8 2015

Hello all

I have been asked to compare schema definitions across 2 DBs, one of which is a PRODUCTION DB.

My plan is to generate a METADATA_ONLY EXPORT of each of the schemas on the PRODUCTION and the SANDBOX DBs (the other DB).

I will create a SCRATCH DB and import using SQLFILE to generate the metadata outputs by alternately importing the same schema from both the dumps.

I will compare the outputs.

QUESTION 1 : Will the METADATA_ONLY export dump file be small since it will have no data ? I will be trying this of course, but I want to be careful before doing this on PROD.

QUESTION 2 : Is this an accurate method - as accurate as using paid-for software. No I do not even want to use SQL Developer's Database Diff.

QUESTION 3 : Will database jobs belonging to a schema be exported ?

QUESTION 4 : Is a METADATA export faster since there is no data ?

FINALLY : Anything I should be worried about ?

Many thanks
