ORA-00001: unique constraint @ impdp with table_exists_action=truncate
Hi everybody
I can't understand why my data pump import execution with parameter TABLE_EXISTS_ACTION=TRUNCATE returned ORA-00001 (unique constraint violation), while importing schema tables from a remote database where the source tables have the same unique constraints as the corresponding ones on the target database.
Now my question is "If the table would be truncated, why I get unique constraint violation when inserting records from a table where the same unique constraint is validated?
Here are the used parameter file content and the impdp logfile.
parfile
{code}
DIRECTORY=IMPEXP_LOG_COLL2
CONTENT=DATA_ONLY
NETWORK_LINK=PRODUCTION
PARALLEL=1
TABLE_EXISTS_ACTION=TRUNCATE
EXCLUDE=STATISTICS
{code}
logfile
{code}
