ORACLE_MAINTAINED Objects Don’t Export

Filed under: 12c,migration,oracle — mdinh @ 5:03 am

What a disaster this is with 12c full database export and ORACLE_MAINTAINED objects.

Somehow, oracle thinks MDINH is an ORACLE_MAINTAINED user and user MDINH does not get exported.

———

Why Can an Object Not Be Exported? Expdp of SYSTEM User’s Table Returns ORA-39166 or ORA-31655 (Doc ID 2114233.1)

There are certain system generated schemas that are not exportable using exp or expdp because they contain Oracle-managed data and metadata. SYS, MDSYS, and ORDSYS are some examples.

———

From Blog about  (ORACLE_MAINTAINED Column) DEMO was ORACLE_MAINTAINED user as well.

For testing purposes, I dropped and recreated the user to test export which removed ORACLE_MAINTAINED flag.

Still, this does not explained how MDINH came to be ORACLE_MAINTAINED user.

Has anyone experience this and has a solution or work around?
