How to stop EJB Schedulers to become timeout for a certain timeperiod in Websphere 8.5

Question

I have an EJB scheduler, This scheduler calls a procedure. The procedure takes 25 minutes to fetch the data.

Now, my EJB scheduler gets timed out before the procedure could get complete.

Is there any way I can configure my EJB schedulers to do not get timed out until the process gets complete or for certain period?

I am using EJB schedulers in WAS 85
