We created a new Reporting Services server that we are now running tests on. I backed up our production ReportServer & ReportServerTempDB databases and restored them to the new server keeping RS off. After a few weeks, I turned Reporting Services on on the new server for testing and it started running / sending subscriptions that were "missed" since the restore time. I shut down reporting services to research.
Even though Reporting Services was stopped, I learned that subscriptions were being queued b/c both the relational engine & sql agent had been running the whole time. As a result, I thought I could restart Reporting Services as long as the sql agent was stopped. I was wrong!!! I don't think any new subscriptions were firing, but a lot of our people were receiving emails for reports executed on the date of the first mishap yet sent today (one week later).
Can anyone explain what is happening? Also, is there a way to clear the queue for the next time we need to turn RS on? I ran some queries that are saying no subscriptions ran the past few days so everything happening must be from before. Thanks!!!
