SQL 2008 Change Tracking Retention Period failing

HI guys -

I have a database set up with change tracking. Initially I set it up with 3 days as the initial repletion period. Then I changed it (via the interface in ssms) to 30 days. Clicked ok. I checked in the cdc table ( I forget which one) to make sure that it was actually set to 30 and not to 3 and it said 30.

Problem is - it's still dropping my changes after 3 days. So I know I did something wrong.

Any clues what I did/how I can get my data to stay around longer without rebuilding the entire thing?

Thanks!

Sadly no...that just confirms that my retention period is set to 30. And my retention period units are set to 3. Do my retention period units need to be set to 1?

>>And my retention period units are set to 3<< I'm not following you here. I think retention period unit should be "Days" not a number...

Here's what I get when I do a select * from sys.change_tracking_databases  .. It's database_id, is_auto_cleanup_on, retention_period, retention_period_units, retention_period_units_desc  (kinda jumbled in the thing below)
database_id is_auto_cleanup_on retention_period retention_period_units retention_period_units_desc
----------- ------------------ ---------------- ---------------------- ------------------------------------------------------------
7           1                  30               3                      DAYS

Oh, I see it now.


Regarding the links I've posted above, so basically you're saying that you have already installed the hotfixes suggested in the links above aren't you?

Also are you running on a replicated database? Check this link for some pointers

1st post: I don't know if I have or not...I generally don't manage the hotfixing. I'll figure out how to check to see if they're there. I'm assuming I have to restart the service in order for them to get applied?

And no on the replication. Just a basic server - couple of databases on it. 2/3 change tracking enabled

Yeah, you should make sure you have the latest patch applied. That will probably require you to restart the service, so just be careful with the timing.

It was a good shot in the dark but didn't seem to work. I just took off the "auto cleanup" and will do that manually and hope I don't lose my stuff that way. Thanks for the help!
