database - Export from Oracle dump file into PostgreSQL -


i have project combine data multiple oracle servers single data warehouse based on postgresql. data oracle servers comes in form of dump files since it's not possible have direct connections of them.

after analyzing 1 of these dump files in hexadecimal editor found table definitions stored in xml format there , possible extract after investigation. unfortunately, data stored in unreadable form hardly can parsed.

did solve such task before? there application or api automate project (at least part of it)?

when mean dump, consider backup taken using either traditional exp or datapump. experience, there no complete way read these dumps.

you can use strings command see of characters inside dump. see junk characters here.

[oranaxx@dtqlnxxx expdp]$ strings test22_schema_.dmp|more "sys"."sys_export_schema_01" x86_64/linux 2.4.xx al32utf8 lbb emb ghc jwd sd ebe wmf ddg jg sjh srh jgk cl egm bjm rap rlp rp kr par ms mrs jls cet hlt 10.02.00.00.00 hdr>t

as @vercelli pointed out, can import dumps temp database , read data tables 1 of ways.
