The above proc when called with the foll. will give the SQLs for all users:

set head off
set pages 0
set serveroutput on size unlimited
spool /tmp/sqls_gathered_frm_trial_run_1.sql
exec get_case_sqls_for_ddls_ver1 
spool off

These SQLs generated can in turn be run as follows to get the master-list of all the grants in the database:

spool /tmp/grants_by_running_trial3_ver0.0.sql
conn  / as sysdba
set head off
set long 1000000000
set pages 0
exec DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SQLTERMINATOR',TRUE);
@/tmp/sqls_gathered_frm_trial_run_1.sql
spool off
