Last updated on AUGUST 04, 2018

Applies to:

Oracle Server - Enterprise Edition - Version: 10.2.0.5 to 11.2.0.1 - Release: 10.2 to 11.2
Information in this document applies to any platform.

Symptoms

 You try to move the staging table (STS) using the DataPump export/import and during the import execution the following error is raised:

ORA-31693: Table data object "TC"."STG_TC_DB_CPLANS" failed to load/unload and is being skipped due to error:
ORA-02354: error in exporting/importing data
ORA-39779: type "SYS"."SQL_PLAN_STAT_ROW_TYPE" not found or conversion to latest version is not possible

The example below shows the issue:

-- source database (10.2.0.5) created with NLS_LENGTH_SEMANTICS=CHAR
sqlplus tc/tc
alter user tc default tablespace users;
create table test (n number );

-- populate the table
begin
  for i in 1 .. 10000 loop
    insert into test values (i);
  end loop;
  commit;
end;
/

create index test_idx on test (n);

analyze table test estimate statistics;

insert into test values (121212);
commit;

connect / as sysdba

-- run CREATE_SQLSET procedure to creates an empty STS
BEGIN
  DBMS_SQLTUNE.CREATE_SQLSET (sqlset_name => 'STS_TESTCASE_10205_11202',
    description => 'STS for testcase_10205_11202');
END;
/

-- load the data in STS_TESTCASE_10205_11202:
DECLARE
  cur DBMS_SQLTUNE.SQLSET_CURSOR;

BEGIN
  OPEN cur FOR SELECT VALUE(P) FROM table (DBMS_SQLTUNE.SELECT_WORKLOAD_REPOSITORY (167, 168, 'parsing_schema_name NOT IN (''DBSNMP'')', NULL, NULL, NULL, NULL, 1, NULL, 'ALL')) P;
 
    DBMS_SQLTUNE.LOAD_SQLSET (sqlset_name => 'STS_TESTCASE_10205_11202', populate_cursor => cur, load_option => 'MERGE', update_option => 'ACCUMULATE');
END;
/

-- create the staging table
BEGIN
  DBMS_SQLTUNE.CREATE_STGTAB_SQLSET (table_name => 'STG_TC_DB', schema_name => 'TC', tablespace_name => 'SYSAUX');
END;
/

-- export of the STS in the staging_table STG_TC_DB
BEGIN
  DBMS_SQLTUNE.PACK_STGTAB_SQLSET (sqlset_name => 'STS_TESTCASE_10205_11202', sqlset_owner => 'SYS', staging_table_name => 'STG_TC_DB', staging_schema_owner => 'TC');
END;
/

 Export the staging table with:
