DBMS_Scheduler Table stats collection issue

Hi Team,

I want to schedule table collect stats through SQL developer by using DBMS_Scheduler. I tried the query like below and the job creation is success but it is failed to run.

Create job:

BEGIN

DBMS_SCHEDULER.CREATE_JOB (

   job_name             => 'STATSNEW',

   job_type             => 'PLSQL_BLOCK',

   job_action           => 'BEGIN DBMS_STATS.GATHER_TABLE_STATS("SREE", "XYZ",estimate_percent=>20,block_sample=>TRUE,degree=>4); end;/',

   start_date           => '12-FEB-2018 10:35:00AM',

   repeat_interval      => 'FREQ=HOURLY',

   enabled              =>  TRUE,

   comments             => 'Gather table statistics');

END;

/

PL/SQL procedure successfully completed.

Execution output:

select log_id,job_name,status,log_date

from dba_scheduler_job_run_details
