Quick tip: Speeding up deletes from SSIS execution log

Eduardo Pivaral, 2019-02-26 (first published: 2019-02-11)

If you have SQL Server Integration Services installed on your server, and you left the default configurations a table named sysssislog is created on MSDB database, it contains logging entries for packages executed on that instance.

If you are not careful enough, this table can grow uncontrollably over time and can make subsequent insertions very slow.

A proper deletion process must be put in place, so you not get into situations like this one in your msdb database:

If you are already on this situation, you can the following T-SQL Script to delete records by batches:

DECLARE @date_del datetime,
@batch_size int = 1000, -- will delete on batches of 1000 records
@RowsAffected int =1

-- Time to keep in the history, in our case 1 month
SET @date_del= DATEADD(mm,-1,getdate());

SET NOCOUNT ON;

WHILE (@RowsAffected >0)
BEGIN
DELETE TOP(@batch_size)
FROM [dbo].[sysssislog]
WHERE starttime < @date_del;

SET @RowsAffected = @@ROWCOUNT;

-- If you want to know rows affected, uncomment this:
-- PRINT @RowsAffected;
END

SET NOCOUNT OFF;

After that you can implement the same query to your msdb maintenance job to have all in one place.

Speaking at Community Events – More Thoughts

Last week I posted Speaking at Community Events – Time to Raise the Bar?, a first cut at talking about to what degree we should require experience for speakers at events like SQLSaturday as well as when it might be appropriate to add additional focus/limitations on the presentations that are accepted. I’ve got a few more thoughts on the topic this week, and I look forward to your comments.
