HI ,
We ahve change tracking enabled on one of our server an year back (SQL Server 2008 + SP1), we are seeing the "'sys.syscommittab'" is 50 GB in size and anything running on that instance is very slow and its observed IO issues.
now the fix for this is to upgrade to SP3 - which is not an option at the moment due to vendor support for the product and other infrastrucutre decisions (its is planned to happen after a month)
mean while can anybody help in reducing the size of this table (the retention is 2 days and can see data in the table of one year old).
We have tried - Disable change tracking - Recycle services - Enable it back ==> no change to the size of the table
is there any official blog to purge this manually?
we see this issue in SQL 2012 as well - but its resolved by executing coutinous CHECKPOINT which in tern delete the records from the table.
