DBMS_SCHEDULER not working oraoperator oracle deployed pod

[alinaqvion-hash]

We have tried scheduling the backup using DBMS_SCHEDULER, which is not working. Is this supported in container environment?

SQL>
SQL> BEGIN
DBMS_SCHEDULER.create_job(
job_name => 'RMAN_FULL_BACKUP_JOB',
job_type => 'EXECUTABLE',
job_action => '/home/oracle/rman_full_backup.sh', -- path inside the pod
start_date => SYSTIMESTAMP,
repeat_interval => 'FREQ=HOURLY; INTERVAL=1', -- run every 1 hour
enabled => TRUE,
auto_drop => FALSE,
comments => 'RMAN Full Backup every 1 hour inside OraOperator pod'
);
END;
