The next example demonstrates how to perform this operation.

In this example,  you have the following environment, you have 20 schemas in your database:

SQL> select username from dba_users;

USERNAME
------------------------------
SYSTEM
SYS
MGMT_VIEW
SYSMAN
DBSNMP
TESTUSER
SCOTT
OUTLN
SI_INFORMTN_SCHEMA
ORDPLUGINS
XDB
WMSYS
EXFSYS
ANONYMOUS
ORDSYS
MDSYS
TSMSYS
ORACLE_OCM
DIP
MDDATA

20 rows selected.


You want to export the entire database but want to exclude the SYSTEM and SCOTT only while using the DataPump API.

To perform this operation from the command line for the data pump export (expdp) looks like:
expdp system/passwd directory=DATA_PUMP_DIR dumpfile=EXPDAT%U.DMP FULL=y exclude=schema:\"IN \(\'SCOTT\',\'SYSTEM\')\"

Solution

The equivalent operation using the Data Pump API PL/SQL code to perform the same operation would looks like:

connect system/passwd
declare
h1 number; -- Datapump handle
dir_name varchar2(30); -- Directory Name

begin
dir_name := 'DATA_PUMP_DIR';
h1 := dbms_datapump.open(operation =>'EXPORT',
job_mode =>'FULL',
job_name =>'FULL MINUS SCHEMAS',
version => 'COMPATIBLE');



dbms_datapump.set_parallel(handle => h1, degree => 1);

dbms_datapump.add_file(handle => h1,
filename => 'EXPDAT.LOG',
directory => dir_name,
filetype => 3);

dbms_datapump.set_parameter(handle => h1,
name => 'KEEP_MASTER',
value=> 0);

dbms_datapump.add_file(handle => h1,
filename => 'EXPDAT%U.DMP',
directory => dir_name,
filetype => 1);

dbms_datapump.set_parameter(handle => h1,
name => 'INCLUDE_METADATA',
value => 1);

dbms_datapump.set_parameter(handle => h1,
name => 'DATA_ACCESS_METHOD',
value => 'AUTOMATIC');

dbms_datapump.metadata_filter(handle => h1,
name => 'NAME_EXPR',
value =>'NOT IN(''SCOTT'',''SYSTEM'')',
object_type => 'SCHEMA');

dbms_datapump.set_parameter(handle => h1,
name => 'ESTIMATE',
value =>'BLOCKS');

dbms_datapump.start_job(handle => h1,
skip_current => 0, abort_step =>0);
dbms_datapump.detach(handle => h1);


end;
/


Upon review of the export log file (EXPDAT.LOG), you will be able to see from that the export excluded the SYSTEM and SCOTT schemas from the full export.
