Option one is to reorganize the indexes when fragmentation is between 10 and 40 percent. In those cases, generally speaking you shouldnвЂ™t need to worry about it.Д«ased on your findings, you have two options as mentioned above. Index rebuilding process uses more CPU and it locks the database resources and requires DPM to be turned off while it runs.ДЄ caveat to this is that if you have fragmentation percentages higher than the suggested numbers but the fragmentation count is low (which is possible after rebuilding). Index should be reorganized when index fragmentation is between 10% to 40%. Index should be rebuild when index fragmentation is greater than 30% or 40%. I have some general suggestions below but please note that these values are guidelines, not hard and fast rules. Using these steps, you can identify how many tables have high fragmentation and determine if you should rebuild or simply reorganize. To determine the amount of fragmentation in your given database. On the top line, change the USE DPMDB command to reflect the correct name of the database in your environment.ДҐ. Copy the query above into the query window. Expand Databases to show the name of the database you will need to run this against.ДЈ. To run the query, open SQL Management Studio (you may have to вЂњRun as AdministratorвЂќ).ДЎ. Order by avg_fragmentation_in_percent desc

SELECT OBJECT_NAME(object_id),index_id, avg_fragmentation_in_percent, fragment_count, page_count, avg_fragment_size_in_pages, index_type_descДЇROM sys.dm_db_index_physical_stats(DB_ID(), Null,Null,Null,Null)ДЄND index_type_desc IN('CLUSTERED INDEX', 'NONCLUSTERED INDEX') Be sure to change this within the script to reflect your DPMDB name. Most servers will likely have a different DPMDB name (usually DPMDB_Comuptername). Specifically, this will show how many indexes have >30% fragmentation and how many tables there are at that level.ДЇor the name. The following script can be run against your DPMDB to determine the amount of fragmentation. SQL Server - Reorganize and Rebuild IndexesДatabase maintenance in relation to reorganizing or rebuilding indexes in the DPMDB will vary by workload. More information on this topic from a SQL standpoint can be found here: , which will drop and re-create the indexes.Д«oth methods have a small side effect of reclaiming some disk space by compacting. , which is a light weight job that will defragment the leaf level of clustered and non-clustered indexes on tables, and When fragmentation happens, SQL has two ways it can address the issue: As tables grow and shrink, this fragmentation can ultimately play a role in how well SQL runs. SQL databases, similar to the file system on a disk, will fragment over time. This article breaks this down into four phases: Well, depending on how long your DPM server has been running, this may not be the case and there are some things you can do to try to help with that. The reality of things is that many DPM admins are not also SQL admins but theyвЂ™re still stuck with hoping their DPM database is optimized.

The other question concerns DPMDB optimization.

First is how to manage the size of the database, although I wonвЂ™t be going into detail on that here as that is covered in my next blog on this series. I often hear questions around maintenance of the DPM database and there are two areas where these questions come in. This installment covers identifying and dealing with fragmentation in your DPMDB, and if you happened to miss Part 1 you can find it here:ДPMDB Maintenance: Database consistency check and your DPMDB
