SQL> begin
2 DBMS_LOGMNR_D.BUILD(
3 dictionary_filename => 'orcldict.ora',
4 dictionary_location => 'c:\tmp');
5 end;
6 /
DBMS_LOGMNR_D.BUILD(
*
ERROR at line 2:
ORA-06550: line 2, column 4:
PLS-00201: identifier 'DBMS_LOGMNR_D.BUILD' must be declared
ORA-06550: line 2, column 4:

Also when i am trying from SVRMGR:

SVRMGR> execute dbms_logmnr_d.build('orcldict.ora', 'c:/tmp');
ORA-06532: Subscript outside of limit
ORA-06512: at "SYS.DBMS_LOGMNR_D", line 793
