TARGET - activate ftp over xdb on port 3100 and open port with iptables:

     $ sqlsys_DB
     SQL> exec dbms_xdb.setftpport(3100);
     SQL> exit
     $ ...

Note: to change ftp params such as session timeout see: http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb22pro.htm#sthref2260

TARGET - changed character set to WE8ISO8859P9 (must be the same as source)

     $ scp exp_tts.dmp oracle@itrac03:work/jwojcies

   *** The datafiles parameter can be generated in the source database 
       with use of the following SQL statement:
   SELECT file_name || ',' FROM dba_data_files WHERE tablespace_name LIKE '%&period%';

SOURCE - create a directory to store in the file with exported metadata and execute the procedure 'EXPORT_METADATA' from the 'COMPASS_METADATA_MIGRATION' package to export metadata related to the migrated period:

     SQL> CREATE OR REPLACE DIRECTORY temp_dir AS '/tmp';
     SQL> exec COMPASS_METADATA_MIGRATION.EXPORT_METADATA('%&period%');

Edit the generated SQL script ('/tmp/compass_metadata_ddl.sql') prefixing trigger's condition clauses with appropriate schema name:

     e.g. In the "COMPDST_02P2F"."ALL_FILES_TRG" trigger change: 
     instead of update on all_files

     to 
 
     instead of update on COMPDST_02P2F.all_files

Remove also the following grant:

     GRANT SELECT ON "SYS"."USER_SEGMENTS" TO PUBLIC;

Scp modified script to the target system:

     $ scp /tmp/compass_metadata_ddl.sql oracle@itrac03:work/jwojcies

TARGET - execute twice the script generated in the previous step.

     $ sqlsys_DB
     SQL> @compass_metadata_ddl.sql
     SQL> @compass_metadata_ddl.sql

BOTH - verify whether all objects and all privileges have been migrated correctly:

     SQL> DEFINE period=02P2F;
     SQL> COL OBJECT_NAME FOR a30;

     SQL> select owner, object_name, object_type, status from dba_objects where owner LIKE '%&period%' order by 3,1,2;

     SQL> select r.granted_role, p.privilege from dba_role_privs r, dba_sys_privs p where r.granted_role=p.grantee(+) and r.grantee LIKE '%&period%' ORDER BY 1,2;

     SQL> select CONSTRAINT_NAME, CONSTRAINT_TYPE, TABLE_NAME, STATUS from dba_constraints where owner LIKE '%&period%' ORDER BY 1,2,3;

     SQL> select grantee, privilege, table_name, grantor from dba_tab_privs where grantor LIKE '%&period%' order by 4,3,2;

Eliminate differenced if needed.

TARGET - make tablespaces READ WRITE:

     SQL> @make_ts_read_write_gen.sql
     SQL> @make_ts_read_write.sql
