How the cdc retention value can be changed for the cleanup job?

Question

Hi there.

I'm implementing a logging feature on a asp.net mvc2 application, that uses SqlServer2008 as a database and Entity Framework as a data model.

I enabled CDC feature of SqlServer and it's logging changes well, but I just noticed that some of the old logging data is erased.

Does anyone know what's default period CDC keeps records, and does anyone know how could I set it to indefinite value.

Answer 1

I just discovered that the default retention value is 4320 minutes = 72 hours = 3 days.

It should be configurable by using

sp_cdc_change_job @job_type='cleanup', @retention=minutes

The maximum value is 52494800 (100 years). If specified, the value must be a positive integer. Retention is valid only for cleanup jobs.

Here's the link to the more detail explanation of sp_cdc_change_job procedure

Hope this will help someone else, too :D.
