Synchronization Issue

Posted by Community Admin on 19-Feb-2014 00:00

Hi, we had a synchronization that has been stuck at 50% for the past few days. I followed the steps at www.sitefinity.com/.../sitesync-stuck and now the sync will finish but any item that attempts to synchronize times out. On the client, I see:

Telerik.Sitefinity.Pages.Model.PageNode: "Test" Message: GetResponse timed out

("Test" is the name of the page I updated to see if it would sync)

On the destination's error log, I see the event log entry listed below.

Any ideas how to resolve are appreciated.

Hello Jason,

This issue could be caused when on destination site already exists a page with the same url like the page that is being synchronized from source site.

According to Sitefinity documentation following prerequisite should be met:
"The target and the source databases must be the same. Sitefinity synchronizes only the content, not the database itself. Before you setup synchronization, copy the database, so that it is the same on both locations."

If the advices above do not resolve the case, please, open a support ticket and provide us with project, configuration and database in order to investigate the problem locally!

Let us know if you need further assistance!

Milena

Hi,

We manually copied database and site files from staging to production, and we received failures. We then tried clearing the sf_scheduled_tasks and sf_site_sync_log_entry tables, and that also failed. We are seeing errors as follows:

The staging server "Test Connection" button indicates "All servers are available".

PS: we do have a support ticket in 789626, but I'm posting this here in case somebody has info. I'll also post the solution here for others' benefit, assuming that we get this fixed.

Thanks

Some more info...

On a whim, I set up Fiddler on the staging server and updated web.config to use it as a proxy. I confirmed that I was able to Test Connection successfully. The staging server sent "/Sitefinity/Services/SiteSync/SiteSyncService.svc/ConfirmConnection/ " and received back an HTTP/1.1 200 OK, with contents of "true"

However, when synchronizing an updated page, it appears that the response time from the production server exceeds that which the staging server is willing to wait. In this instance, the response came in 2 minutes, 5 seconds. The response from the production sever was an HTTP/1.1 200 OK, with zero bytes of content. Is there a way to turn up the timeout threshold on the staging (sending) server?

Hello,

You could also try to clear your search index data and re-create it. This could solve the problem as there was a known issue with some of the earlier Sitefinity versions when perfoming SiteSync.

Another possible solution could be to raise your HttpBindings as described in MSDN:
http://msdn.microsoft.com/en-us/library/hh924831(v=vs.110).aspx
