During schema import with datapump.
the following error occurs.
ERROR
-----------------------
> > > DRG-11313: populate index error on index partition "PART_21"

The error appears because expdp utility exports the internal text-index table ($P). So, the drvxtab.create_index_tables cannot create an index because the object name is occupied during import of the schema with impdp.
It happens that after running ctx_ddl.optimize_index on the index - the obj$.flags is set to 0 for the $P-table of the text-index. And this allows expdp to export the internal index table as an ordinary table.
Such behaviour takes place for partitioned and non-partitioned indexes.
