CURRENT DB Organization : 20 DB on 4 SQL Server inst. • SharePoint Databases • SessionStateService (L01) • StateService (L01) • WAT_CONFIG (L01) • WAT_SVC_UserProfileService_Profiles (L01) • WAT_SVC_UserProfileService_Social (L01) • WAT_SVC_UserProfileService_Sync (L01) • WAT_SVC_SearchService (L01) • WAT_SVC_SearchService_AnalyticsReportingStore (L03) • WAT_SVC_SearchService_CrawlStore (L03) • WAT_SVC_SearchService_LinksStore (L03) • WAT_SVC_MetaDataService (L04) • WSS_UsageApplication (L01) • Content Databases • WAT_CONTENT_CentralAdmin (L01) • WAT_CONTENT_Common (L01) • WAT_CONTENT_CommunitySites1 (L01) • WAT_CONTENT_Content_site (L01) • WAT_CONTENT_Personal_Sites1 (L01) • WAT_CONTENT_THEMATICS (L02) • OtherDatabases • AIGImport (L01) • CacheDb (L02) WAT - Atelier "Sites Distants" - Cadrage des tests

  4. Reasons to change DB Organization • The content databases are expected to grow as the number of userspicks up • The MS recommandation is to keep DB sizesunder 400 GB • This leads us to split DB. WAT - Atelier "Sites Distants" - Cadrage des tests

  5. Splitting the databases • Editorial Content • Currently : WAT_CONTENT_Common, WAT_CONTENT_site, WAT_CONTENT_THEMATICS • Planned : 9 databases • Personal Sites • Currently : WAT_CONTENT_Personal_sites_1 • Planned : 120K user profiles, max number of sites per base = 10KIn the run, the personal sites must use 12 DBs. • Community Sites • Currently : WAT_CONTENT_Community_sites1 • Planned : average size of a community site = 5 GB, 80 communities per DBExpectednumber of communities = 5000, Nb of DB = 70These DB canbeprovisionnedprogressively WAT - Atelier "Sites Distants" - Cadrage des tests

  6. SQL Cluster Administration • Database log files sizes • Supervision • Maintaining SQL Server instances on theirpreferrednode WAT - Atelier "Sites Distants" - Cadrage des tests

  7. CONTENT DATABASES LOG FILES • The content databases are saved by DPM • DPM isexpected to truncate and shrink the log files • For somereason, log files are not handled as expected. • It mightbenecessary to truncate and shrinkmanually • The DB SessionStateServicegrowswith no limit • The issue isunder investigation by Microsoft Premier • Loggingparameters must beadjusted for some of the other DB • Who has the responsibility to makethese changes ? • The growth of files beyondlimitsdoes not trigger alerts • Which supervision is in charge ?

  8. Instances and Nodes • The SQL cluster is made of 6 physicalnodes • E01, E02, E03 (Saint-Denis) • E04, E05, E06 (Clichy) • When running in the standard mode: • L01, L03, L04 run on node E03 • L02 run on node E01 • In case of the loss of a physical server, the instances are moved to the nextavailablenode in theirpreferencelist. • At reboot of theirnode, instances are moved, but theirshould return to theirpreferrednodeafterrebbotiscomplete.
