RETURN VARCHAR2
IS
l_str   VARCHAR2 (255) DEFAULT NULL;
l_fno   VARCHAR2 (15);
l_bno   VARCHAR2 (15);
BEGIN
l_fno :=
DBMS_UTILITY.data_block_address_file (TO_NUMBER (LTRIM (p_dba, '0x'),
'xxxxxxxx'
)
);
l_bno :=
DBMS_UTILITY.data_block_address_block (TO_NUMBER (LTRIM (p_dba, '0x'),
'xxxxxxxx'
)
);
l_str :=
'datafile# is:'
|| l_fno
|| CHR (10)
|| 'datablock is:'
|| l_bno
|| CHR (10)
|| 'dump command:alter system dump datafile '
