DEFINITION:

A database maintenance plan is a set of specific, proactive task

that need to be performed regularly on databases

to ensure their adequate performance and availability

HOW:

Maintenance Plan Wizard

Maintenance Plan Designer

T-SQL Scripts

PowerShell Scripts

WHERE

SQL Server Management Studio from Standard and above

See you in… Express

WHEN:

BEFORE: problems / service windows

AFTER: maintaining / clients back to home

SQL Relay 2014 | Birmingham Oct 14th | KoprowskiT - Maintenance Plans for Beginners 10

Very simple (although advanced) wizard

Providing possibility for creation simple task in dozens of seconds

Enough in many cases, environments

Limited but include many options

Limitations:

number of databases

granularity

single tasks / no multitasking

no scripting for another instances

some known problems in previous version of SQL Server

SQL Server 2005 Service Pack 2 / SQL Server 2008

SQL Relay 2014 | Birmingham Oct 14th | KoprowskiT - Maintenance Plans for Beginners 11

More flexible and advanced tool (not on this session)

Graphical user interface with SSIS

Most often used for „real DBA”

Increased features

Workflow for specified tasks with execution plan

Multitasking

Two additional Maintenance plans

Execute T-SQL Statement

Notify Operator

SQL Relay 2014 | Birmingham Oct 14th | KoprowskiT - Maintenance Plans for Beginners 12

Limitations for both tools / those ideas are not possible

Identification and removing fragmentation for physical files

Identification abandoned, duplicated, forgotten indexes

Providing backup on demand

Werification good quality of backup

Werification succesful restore

Monitoring of performance

Monitoring of SQL OS

Monitoring of Windows OS

Monitoring available space

SQL Relay 2014 | Birmingham Oct 14th | KoprowskiT - Maintenance Plans for Beginners 13

Functionality for „Real *Tru* DBA”

Necessary for working with multiple databases, instances, server farms

Feauters for scripting:

Access to OS

Posibility of moving

Scripts sharing

One of the best examples and tools for free:

The SQL Server Maintenance Solution comprises scripts for running backups, integrity checks, and index and statistics maintenance on all editions of Microsoft SQL Server 2005, SQL Server 2008, SQL Server 2008 R2, SQL Server 2012, and SQL Server 2014.

The solution is based on stored procedures, the sqlcmd utility, and SQL Server Agent jobs. I designed the solution for the most mission-critical environments, and it is used in manyorganizations around the world.

Numerous SQL Server community experts recommend the SQL Server Maintenance Solution, which has been a Gold winner in the 2013, 2012, 2011, and 2010 SQL Server Magazine Awards. The SQL Server Maintenance Solution is free.

“After you review this checklist run — do not walk — over to this website: http://ola.hallengren.com. Download, read, understand and implement these scripts. My

friend Ola has done a better job on these scripts than I’ve seen anywhere else, hands down.” - Buck Woody

Check Database Integrity | DBCC CHECKDB

Shrink Database | NEVER, NEVER, NEVER

Reorganize Index | ALTER INDEX , and next Update Statistics

Rebuild Index | ALTER INDEX, Update Statistics are not necessary

Update Statistics | sp_updatestats

History Cleanup | using msdb, don’t do that too much frequently

Execute SQL Server Agent Job | providing scripts using wen you work with agent

Back Up Database (Full) | executing BACKUP DATABASE with FULL option >>Transaction Log

Back Up Database (Differential) | executing BACKUP DATABASE with DIFFERENTIAL option

Back Up Database (Transaction Log) | executing BACKUP LOG, frequency...

Maintenance Cleanup Task | most complicated feature ? BAK, TRN, TXT

using DBCC CHECKDB

Daily

Weekly

Monthly

DBCC CHECKDB (’database_name’) WITH NO_INFOMSGS

Suppresses all informational messages.

DBCC CHECKDB (’database_name’) WITH NO_INFOMSGS, ALL_ERRORMSGS

Displays all reported errors per object. All error messages are displayed by default. Specifying or omittingthis option has no effect. Error messages are sorted by object ID, except for those messages generatedfrom tempdb database.

In SQL Server Management Studio, the maximum number of error messages returned is 1000.

DBCC CHECKDB (’database_name’) NOINDEX

Specifies that intensive checks of nonclustered indexes for user tables should not be performed. Thisdecreases the overall execution time. NOINDEX does not affect system tables because integrity checks arealways performed on system table indexes

Reorganize Index Task Rebuild Index Task

removing empty

space and logical

fragmentation

Performs a less thorough index

defragmentation than Rebuild Index. If an

index does not have any fragmentation, then

is not reoganized, saving resources.

Virtually all wasted free space and logical fragmentation

is removed. All indexes are rebuild from scratch, whether

they need it or not.

performance

impact

does not require long blocking locks. An

online task that allows users to access the

database duringthe task

requires potentially long blocking locks that prevent

users from accessing the indexes being rebuilt. A task

that should be performed offline, though with the

Enterprise Edition of SQL Server, you can use the online

version of an index

Index Task

Generally runs faster than Reorganize Index Task

Uses less disk space that the Rebuild Index

Task. Uses less space i the transaction log

than Rebuild Index Task

Use more disk space than Reorganize Index Task. More

space is required in the transaction log than the

Reorganize Index.

maintenance

Index and column statistics must be updated

separately. This adds to the administration

hassle.

part of this step, using FULLSCANN option
