Creating Alerts (Cont) Non Fatal ErrorsSELECT * FROM sys.messagesWHERE language_id = 1033 AND is_event_logged = 1 AND severity < 19
Why Do You Need An Administrative Database?

Track Database Sizes for Capacity Planning

What Maintenance Jobs Should You Be Running?
Cycle the Error Log Make sure to increase the number
of log files first. sp_cycle_errorlog
Cleanup the Backup History Be careful if you havea lot of
history. sp_delete_backuphistory
Cleanup Mail History sysmail_delete_mailitems_sp sysmail_delete_log_sp
Maintenance Jobs (Cont)
Update Statistics sp_updatestats
Index Maintenance > 5% and < = 30%
REORGANIZE > 30% REBUILD
Maintenance Jobs (Cont)

Check Database Integrity DBCC CHECKDB
Backups Script Restore to file using backup history tables

Maintenance Considerations When Upgrading a Database
Change Database Compatibility Level ALTER DATABASE [DatabaseName]
SET COMPATIBILITY_LEVEL = 100
Check the integrity of the objects in your database DBCC CHECKDB ([DatabaseName]) WITH DATA_PURITY
Correct Row and Page Counts DBCC UPDATEUSAGE ([DatabaseName])
Set the page verification method to CHECKSUM ALTER DATABASE [DatabaseName]
SET PAGE_VERIFY CHECKSUM WITH NO_WAIT
Update Statistics With Full Scan sp_msforeachtable 'UPDATE STATISTICS ? WITH FULLSCAN'
