SYMPTOMS

DataPump import (IMPDP) fails with error:

ORA-39083: Object type INDEX_STATISTICS failed to create with error.

Note 755253.1 was followed to rectify this. The import excluding indexes runs successfully.

The note says to run the impdp again with the include indexes after first excluding those. With the included indexes, this also generates errors and does not produce the results suggested by the note.
There are three errors types, two of them recur multiple times:

ORA-39083: Object type INDEX failed to create with error:

ORA-01408: such column list already indexed
- OR -

ORA-31684: Object type INDEX: already exists

ORA-39111: Dependent object type INDEX_STATISTICS skipped, base object type
 

CAUSE

The issue is due to unpublished 

Bug 9316756 - IMPORTING STATISTICS USING ORACLE DATA PUMP IS TIME CONSUMING

fixed in Oracle 12.1

The fix will change the dumpfile format of the statistics collected. That is why the fix will be in the next release and will not be backported to previous one.

Please refer to:
Note 9316756.8 - Bug 9316756 - Slow statistics import with oracle data pump / Inaccurate or Wrong Statistics imported

SOLUTION

To address the issue, use one of the below methods:
Re-export with exclude statistics, then import and gather the statistics after import.

- OR -

Run the import excluding the statistics and gather the statistics manually.
