Hi,
yesterday we had some trouble when moving OperationsManager and OperationsManagerDW to a new SQl Server.
This lead to some internet search...at the end it worked.
During internet search I fell over following blog article:
http://blogs.technet.com/b/mihai/archive/2012/05/11/cleaning-up-old-data-from-the-data-warehouse-database-in-om-2007-r2.aspx
As we are permamently suffering from suboptimal performance in the console we executed the analysis script from that blog:
------------------------
DECLARE
@MaxDataAgeDays INT,
@DataSetName NVARCHAR(150)
SET @DataSetName = 'Event'
SELECT @MaxDataAgeDays = MAX(MaxDataAgeDays)
FROM StandardDatasetAggregation
WHERE DatasetId = (
SELECT DatasetId
FROM StandardDataset
WHERE SchemaName = @DataSetName
)
SELECT COUNT(*)
FROM EventCategory
WHERE LastReceivedDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
SELECT COUNT(*)
FROM EventChannel
WHERE LastReceivedDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
SELECT COUNT(*)
FROM EventLoggingComputer
WHERE LastReceivedDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
SELECT COUNT(*)
FROM EventPublisher
WHERE LastReceivedDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
SELECT COUNT(*)
FROM EventUserName
WHERE LastReceivedDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
SELECT COUNT(*)
FROM ManagedEntityProperty
WHERE ToDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
SELECT COUNT(*)
FROM RelationshipProperty
WHERE ToDateTime < DATEADD(DAY, -@MaxDataAgeDays, GETUTCDATE())
-----------------------------
The Result is seven lines (one for each SELECT Statement):
0
8
0
0
1674067
283944
In the quoted blog Mihai mentions: "Now if you get any results here it means that you are experiencing the issue. So you might want to clean these up manually to help OM a little :D
So execute this SQL Query on the Data Warehouse database to clean the old entries "
Should we execute that script ?
Our ManagementGroup was upgraded from SCOM 2007 R2 to SCOM 2012 SP1.
Are these SQL-Scripts still valid for SCOM 2012 SP1 ?
Has somebody else used these scripts ?
Thanks for your time
