Database timeout on product/variant update



This just showed up in our logs. Same code has been running for a long time now without problems.

Any idea what could cause this problem? We are running Commerce 10.5

How many rows do you have in ecfVersion? Can you get the execution plan for this query? 

Oct 16, 2017 13:10

We have 479098 rows in the table.

How do I get the execution plan, I did it once but have forgotten! :-)

And here you can download the execution plan (10000 rows so I don't want to post it here):

I found something interesting, but I'd have to verify them more closely before filing a bug for us to work on it. 

How long does it take for you to run that query? Is it possible to reduce the batch size?

Oct 16, 2017 14:36

My suspicion is on your ecfVersion.IDX_ecfVersion_Indexed_ContentId Index. Make sure it gets defragmented, and its statistics are up-to-date 

Oct 16, 2017 14:45

The query took 2 minutes 23 seconds. 

Tried to run this:

declare @p1 dbo.udttObjectWorkId
insert into @p1 values(96265,0,1358777,NULL)
exec ecfVersion_ListByWorkIds @ContentLinks=@p1
It took 2 minutes 14 seconds.
Query 1-4 executes immediatly while 5-9 takes over 2 minutes.
Is there a workaround for this? Our customer cannot use the Commerce edit GUI since they get a timeout?
Oct 16, 2017 14:49

I have rebuilt all the indexes on ecfVersion and updated statistics but it still takes 2 minutes.

Should I email developer support with a link to a database backup?


Edited, Oct 16, 2017 15:16

Yes, that should be the proper way to handle it. It might end up in my hands eventually - as I'm generally excited for performance improvements - but we should follow the workflow 

Oct 16, 2017 15:18

Ticket has been created and it would be great if you can look at this as soon as possible since our customer cannot work in Commerce edit mode right now. If you have any other idea how we can work around this for now. Maybe delete old versions or something, that would be great!



Oct 16, 2017 16:26

This might be of interest to you 

Oct 17, 2017 9:21

Another update:

we will incorporate these changes in an upcoming version 

Oct 21, 2017 9:25

Hi Quan!

Today we got an exception in this function:

Mediachase.Commerce.Catalog.CatalogContent.CatalogContentSync.CreateDraft(CatalogNodeDto nodeDto, String changedBy) 

It looks like it was this procedure that caused the timeout:


Also an ecfVersion procedure. Maybe there is something there that also needs to be updated?


Oct 26, 2017 15:25

That would be not enough for us to look into the problem. As usual an execution plan (and usually the database) is needed. As always support service is the way to go
