Impdp with remap failing on POST_TABLE_ACTION still using old schema - oracle

Question

I'm trying to import an oracle dump while remapping schema and tablespace:
impdp usr/pass \
EXCLUDE=table_statistics \
DIRECTORY=EXPDP \
REMAP_SCHEMA=ORG_USR:NEW_USR \
REMAP_TABLESPACE=ORG_TS:NEW_TS \
DUMPFILE=FILE.dmp \
PARALLEL=2 \
LOGFILE=FILE.imp.log
The job imports all tables and then starts processing object types:
Import: Release 12.1.0.2.0 - Production on Thu Aug 17 11:13:06 2017
[ ... the import remaps correct ]
Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA

I did specify REMAP_SCHEMA and REMAP_TABLESPACE, and the import runs mostly correct.
BUT at the end part trying Processing object type SCHEMA_EXPORT/TABLE/POST_TABLE_ACTION it somehow fails using the OLD User.
Can someone tell me what ist going wrong and how to fix it?

Answer 1

The soulution was to import excluding post_table_action and execute the statements manually after altering the schemaname to the correct value:
impdp usr/pass \
EXCLUDE=post_table_action \
DIRECTORY=EXPDP \
REMAP_SCHEMA=ORG_USR:NEW_USR \
REMAP_TABLESPACE=ORG_TS:NEW_TS \
DUMPFILE=FILE.dmp \
PARALLEL=2 \
LOGFILE=FILE.imp.log
and
BEGIN
SYS.DBMS_SNAPSHOT_UTL.SYNC_UP_LOG('ORG_USR','TABLEA');
END;
BEGIN
SYS.DBMS_SNAPSHOT_UTL.SYNC_UP_LOG('ORG_USR','TABLEB');
END;
BEGIN
SYS.DBMS_SNAPSHOT_UTL.SYNC_UP_LOG('ORG_USR','TABLEC');
END;
