Orchestration scheduler not started

Hi Team,

AIS server and JAS server are up and running fine.

However if I login into Orchestration studio and check scheduler "Scheduler not started" is showing up and jobs are not running.

We scheduled on job for every weekday night 2 AM in DV only.

0 0 2 ? * MON-FRI * -- cron job

It ran for 3 days successfully But after that its not running.

We have deleted that scheduled jobs, Orch and restarted AIS and JAS but still its not up.

Below tables still have details about deleted scheduled jobs

select * from AISDVSCHED.qrtz_cron_triggers; -- PFA

select * from AISDVSCHED.qrtz_job_details;
