Schedule gather stats job in scheduler

Hello All,

I am trying to gather schema stats(all tables in specifc schemas) by scheduing a job in scheduler.

Working as expected on a specific table in a schema :

begin

dbms_scheduler.create_job(

job_name => 'GATHER_VENDOR_SCHEMA_STATS_JOB',

job_type => 'PLSQL_BLOCK',

job_action => 'DECLARE

filter_lst  dbms_stats.objecttab := dbms_stats.objecttab();

BEGIN

  filter_lst.extend(3);

  filter_lst(3).ownname := ''DBO'';

  filter_lst(3).objname := ''OI_ORGANIZATION'';

  dbms_stats.gather_schema_stats(

          OWNNAME          => ''DBO'',

          ESTIMATE_PERCENT => DBMS_STATS.AUTO_SAMPLE_SIZE,

          METHOD_OPT      => ''FOR ALL INDEXED COLUMNS SIZE AUTO'',

          DEGREE          => DBMS_STATS.DEFAULT_DEGREE,

          GRANULARITY      => ''ALL'',

              force        => TRUE,
