Bounce Concurrent Manager from backend or using SQL

I have a requirement to bounce Receiving Transaction Manager everyday. So, I was trying to automate this activity. I found below way to bounce it from backend using a script. I had put all the below statements in a script and scheduled in cron.

Find out the short name of the concurrent manager to be bounced, in my case it is Receiving Transaction Manager

SQL> select CONCURRENT_QUEUE_NAME from  apps.fnd_concurrent_queues_tl where USER_CONCURRENT_QUEUE_NAME='Receiving Transaction Manager';
CONCURRENT_QUEUE_NAME
---------------------
RCVOLTM

Check the status of the concurrent manager before bouncing it.

SQL>select control_code,running_processes,MAX_PROCESSES from fnd_concurrent_queues where concurrent_queue_name='RCVOLTM';

Deactivating the concurrent manager:When you deactivate a manager all requests (concurrent programs) currently running are allowed to complete before the manager(s) shut down.

SQL>update fnd_concurrent_queues set control_code='D' where concurrent_queue_name='RCVOLTM';

Set max and target processes to 0

SQL>update fnd_concurrent_queues set running_processes=0,MAX_PROCESSES=0 where concurrent_queue_name='RCVOLTM';
commit;

see the status of the Manager

SQL>select control_code,running_processes,MAX_PROCESSES from fnd_concurrent_queues where concurrent_queue_name='RCVOLTM';

Activating the concurrent manager:

SQL>update fnd_concurrent_queues set control_code='R' where concurrent_queue_name='RCVOLTM';
commit;

See the status of the Manager

SQL>select control_code,running_processes,MAX_PROCESSES from fnd_concurrent_queues where concurrent_queue_name='RCVOLTM';
