Answer 1

Vishal,
Here are 2 options , first you can use either procedure or anonymous block to load clob data
First Method -- I loaded alert.log successfully and you can imagine how big this file can be (5MB in my test case), in your case you need to specify your pdf file. CLOB/BLOB can take upto 4GB data
Make sure you have privs to create , read or write to directory
create table t1clob (
clob_data clob  -- you can use blob
CREATE OR REPLACE DIRECTORY DIR AS '/my_path_to_pdf_file/pdf';
DECLARE
   clob_data   CLOB;
   clob_file   BFILE;
BEGIN
   INSERT INTO t1clob
   VALUES (EMPTY_CLOB ())
   RETURNING clob_text INTO clob_data;
   clob_file   := BFILENAME ('DIR', 'wwalert_dss.log');
   DBMS_LOB.fileopen (clob_file);
   DBMS_LOB.loadfromfile (clob_data,
                          clob_file,
                          DBMS_LOB.getlength (clob_file)
   DBMS_LOB.fileclose (clob_file);
   COMMIT;
END;
Second Method: Use of Sqlldr
Example of controlfile
LOAD DATA
INFILE alert.log "STR '|\n'"
REPLACE INTO  table t1clob
   clob_text char(30000000)
