Subscriptions not being fired in SSRS SharePoint integrated mode

Question

We have a SharePoint farm with SSRS in SharePoint integrated mode. Reports rendering works fine, but suddenly we started to have problems with subscriptions.

The SQL Server agent successfully runs the dbo.AddEvent procedure and a corresponding record occurs in dbo.Event table in the reporting services database. I believe SSRS should pick up these records and run the subscriptions, but it does not (we have a few hundreds of rows in dbo.Event now). Nothing is shown in ExecutionLog3.

We tried to restart the SSRS service, iisreset, restart of the entire farm, nothing helps.

What to do to persuade the SSRS service to process the subscriptions?

We use these versions: MS SQL 2016, SharePoint 2016, Windows server 2016.

Answer 1

I finally made it working, but problem is that I do not know what exactly helped. What I did:

• Changed owner of all the subscription to an account with excessive permissions
• Started the Windows service "SPTimerV4" (probably that was the problem?)
• Unprovisioned and provisioned the SSRS service using PowerShell
• Restarted the SSRS service (central administration - manage services on servers, select the server where the SSRS service is running, find it, stop, start)

Now records in dbo.Event do not hang up any more and subscriptions are being processed (and of course hit the ExecutionLog3).

Hope it helps someone.

Thanks to everybody for your help!
