ORA-31693: Table data object failed to load/unload error

I got ” ORA-31693: Table data object failed to load/unload error ”  error in Oracle database.

ORA-31693: Table data object failed to load/unload error

Details of error are as follows.

ORA-31693: Table data object string failed to load/unload and is being skipped due to error: string

Cause: Table failed to load or unload due to some error.
Action: Check load/unload error, correct problem and retry command.

Import using DataPump will fail with the following errors when the export dump does not contain information about the metadata:

Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA

Table data object string failed to load/unload and is being skipped due to error: string

This ORA-31693 error is related with the Table failed to load or unload due to some error.

When you perform a DataPump export and specify CONTENT=DATA_ONLY, the dump file will not contain the metadata information of the schema objects.

During DataPump import into a different schema or in the same schema where the metadata does not exists, the errors mentioned above will occur.

Confirm, whether the export dump was taken with CONTENT=ALL option. You can verify that by using the SQLFILE parameter in the impdp command line. Then DataPump generates a text file which contains the metadata information that was loaded in the export dump files. If SQLFILE contains no metadata information, then the dump was not exported with CONTENT=ALL.

To solve this error, either pre-create the objects before the import or export using CONTENT=ALL parameter.

Other case is as follows.

1. When performing a full database consistent export with Export Data Pump from a 12.1.0.1 source database, the following errors occur:

For this job, similar ORA-1031 (insufficient privileges) errors are reported for:

2. The problem reproduces when the full database export DataPump job is done with FLASHBACK_TIME as well as with FLASHBACK_SCN.

3. The problem also reproduces if the following privileges are granted to the schema that runs the Export Data Pump job:

-- following privileges do not solve the problem

connect / as sysdba
alter user <USERNAME> quota unlimited on system;
grant unlimited tablespace to <USERNAME>;
grant flashback any table to <USERNAME>;

1. As a workaround, grant the FLASHBACK ANY TABLE privilege and FLASHBACK privilege on the SYS-owned tables that were reported in the earlier export job to the EXP_FULL_DATABASE role, and re-run the export job, e.g.:

connect / as sysdba
grant flashback any table to exp_full_database;

grant flashback on SYS.KU$_USER_MAPPING_VIEW to exp_full_database;
grant flashback on SYS.FGA_LOG$FOR_EXPORT to exp_full_database;
grant flashback on SYS.AUDTAB$TBS$FOR_EXPORT to exp_full_database;
grant flashback on SYS.DBA_SENSITIVE_DATA to exp_full_database;
grant flashback on SYS.DBA_TSDP_POLICY_PROTECTION to exp_full_database;
grant flashback on SYS.NACL$_ACE_EXP to exp_full_database;
grant flashback on SYS.NACL$_HOST_EXP to exp_full_database;
grant flashback on SYS.NACL$_WALLET_EXP to exp_full_database;
