6 SharePoint database maintainability begins with... a solid SharePoint architecture based a well-defined governance strategy and a well-planned deployment

7 Information Architecture Web Application Site Collection Site Collection Content Database Site Collection Site Collection Content Database

8 Default Database Names SharePoint_AdminContent_a11f2b67-db6d ab8- ec6e7b14042e SharePoint_Config SharedServices1_DB SharedServices1_Search_DB WSS_Content WSS_Content_9a9ae c52-8b46-ef4ee71715f0 WSS_Content_3d90d4a5-b8b adb5-02da7697b5f4 WSS_Search_DC1

9 Database Naming Convention Database Initial Size What are all these databases for? SharePoint_Admin_Content 60 MB Site collection content for the Central Administration SharePoint_Config 10 MB Hosts configuration information that is common to all members of the farm SharePoint_Content_Intranet 14 MB Intranet content database SharePoint_Content_MySite 14 MB MySite content database SharePoint_Content_SSP1 14 MB Content database for SSP administration site SharePoint_Search_DC1 60 MB Crawl database of SharePoint help file SharePoint_SSP1_DB 10 MB Shared services specific data SharePoint_SSP1_Search_DB 3 MB Search related data from indexing (Property Store, URL Maps)

10 Service Accounts Setup/Configuration Account (spadmin) Used to run the psconfig utility, SharePoint Product and Technologies Wizard, and to create Web applications Member of the local Administrators group on the SharePoint servers Member of the dbcreator and securityadmin roles in SQL Server Farm Database Access Account (spfarm) Identity of the SharePoint Central Administration application pool Identity of the Windows SharePoint Services Timer service Member of the db_owner role on all Office SharePoint Server 2007 databases within the instance Only account with write access to the SharePoint configuration database Search service, content access, SSP service, Web application process accounts... Windows Authentication strongly recommended for all database access accounts

19 If you have the luxury of being in on and having a say in the configuration of the database pinch yourself. Important pieces to consider when setting things up from scratch: RAID levels File Locations Disk Configuration File sizing

20 RAID Levels RAID 0, 1, 5, 1+0 are ones typically used for SQL Server RAID 0 (striping) not fault tolerant RAID 1 (mirroring) better for writes RAID 5 (striping with parity) most often used due to cost. Great read performance more write overhead RAID 1+0 (striped mirrors) most expensive and of course best for database performance

21 File Locations Databases all have data and log files Separating data files from log files on separate arrays can give great boosts to performance Can set default locations for data and log files

22 Optimal Disk Configuration C:\OS files D:\SQL Server data files E:\SQL Server log files F:\SQL Server tempdb files (one file per processor) G:\SQL Server backups

23 Data/Log File Sizing Best Practice warning: You should size your databases appropriately from the very beginning and do not allow autogrowth. This will eliminate fragmentation of disk.

24 Things to do after setup Maintenance plans Database mail and operators Setup alerts Job failure notifications

25 Integrity checks End all be all vital thing that must be done no matter what Detects corruption (torn pages) If corruption occurs the last step in the fix it book is to restore from backup. If you have never done a integrity check good luck figuring out when corruption occurred I recommend daily

26 Reindexing SharePoint uses GUIDs for primary keys this can lead to heavy fragmentation If on 2005 prior to SP2 don t do via maintenance plan Conditional reindexing best Fill factor 70 said to be best for SharePoint (general rule for dbs is 80 or even 90)

27 Give me some warning You can get alerts/notifications for all kinds of bad mojo going on in SQL Server. 1. Setup Database Mail 2. Setup an operator 3. Setup alerts (17 25, log full, io, memory) 4. Job failure notifications 5. Threshold alerts if need calls for it

28 Show and Tell Defaults for data/log files Change file growth/max Add files for tempdb Setup Maintenance plans Setup operator and alerts Additional things can do with alerts Time permitting: Database mail
