I have a workflow which have an event, sql job and unix job as below. 
The event will check the source data (through sql query) every 5 min.  The requirement is if the source data is not ready in 2 hrs. an email has to be triggered to users and continue checking the source data.  If source data available then it will continue with the normal sequence (continue with sql job)

Event > SQL job > Unix Job

Could anyone help me on this.
