Symptoms
You created a database link with connection qualifiers: connect system/password
create public database link x102a.oracle.com@qual1 connect to system identified by password using '<tns-alias>';
and then started DataPump import to extract a schema from remote database:
#> impdp system/passwd directory=dpu logfile=impdp_test.log schemas=test network_link=x102a.oracle.com@qual1
This raised the errors: Import: Release 10.2.0.4.0 - 64bit Production on Monday, 16 February, 2009 15:56:12

With the Partitioning, Data Mining and Real Application Testing options
ORA-39004: invalid state
ORA-39091: unable to determine logical standby and streams status
ORA-26667: invalid STREAMS parameter x102a.oracle.com@qual1
Alternatively, when DataPump is started with DataPump API:
connect system/passwd
set serveout on
create or replace procedure CopySchema
(
pschemafrom in varchar2,
pschemato in varchar2,
net_link in varchar2
) is
hand number;
vmessage varchar2(2000);
begin
hand := dbms_datapump.open (operation => 'IMPORT',
job_mode => 'SCHEMA',
remote_link => net_link);
dbms_datapump.add_file (handle => hand,
filename => 'impdp_test.log',
directory => 'DPU',
filetype => dbms_datapump.ku$_file_type_log_file);
dbms_datapump.metadata_filter (handle => hand,
name => 'SCHEMA_LIST',
value => 'TEST');
dbms_datapump.start_job (hand);
exception
when others then
vmessage := sqlerrm;
dbms_output.put_line (vmessage);
end;
/
SQL> exec CopySchema (pSchemaFrom => 'TEST', pSchemaTo => 'TEST', net_link => 'X102A.ORACLE.COM@QUAL1');
set serveout on
create or replace procedure CopySchema
(
pschemafrom in varchar2,
pschemato in varchar2,
net_link in varchar2
) is
hand number;
vmessage varchar2(2000);
begin
hand := dbms_datapump.open (operation => 'IMPORT',
job_mode => 'SCHEMA',
remote_link => net_link);
dbms_datapump.add_file (handle => hand,
filename => 'impdp_test.log',
directory => 'DPU',
filetype => dbms_datapump.ku$_file_type_log_file);
dbms_datapump.metadata_filter (handle => hand,
name => 'SCHEMA_LIST',

dbms_datapump.start_job (hand);
exception
when others then
vmessage := sqlerrm;
dbms_output.put_line (vmessage);
end;
/
SQL> exec CopySchema (pSchemaFrom => 'TEST', pSchemaTo => 'TEST', net_link => 'X102A.ORACLE.COM@QUAL1');
ends with:

ORA-39004: invalid state

and the written logfile contains:
