18.To find out is there anything running on Trace :
===============================================
1.To stop the profiler trace before its end time has occurred you exec two commands.
One stops the trace and the other closes the trace file.
2.Here are the commands:
a.Execute "select * FROM ::fn_trace_getinfo(default)"
b.Identify the traceid you using the folder name specified when starting the trace.
c.Execute these two commands replacing # with the trace id.
EXEC sp_trace_setstatus @traceid = #, @status = 0; -- Stop/pause Trace
EXEC sp_trace_setstatus @traceid = #, @status = 2; -- Close trace and delete it from the server
3.Verify it has stopped by executing "select * FROM ::fn_trace_getinfo(default)"
4.To view the captured trace files, open them using SQL Server Profiler.
5.Old profiler trace files are not automatically deleted. You will need to delete them your-self when you are finished.
19.How to shutdown, restart, logoff using command prompt?
==========================================================
shutdown -OPTION
OR
shutdown /OPTION
-l – Logs off the current user

21. To find out logshipping status :
=======================================
You can use the Log Shipping Status report by right clicking on the Server Name in Management Studio > Reports > Standard Reports > Transaction Log Shipping Status.
sql server standard reports options
You can execute the below Log Shipping System Stored Procedure to monitor log shipping and get detailed information about log shipping.
* sp_help_log_shipping_monitor
o This is the how SQL Server generates the Log Shipping Status report by executing sys.sp_help_log_shipping_monitor procedure. This procedure returns the log shipping status (whether it is healthy or not) as well as metadata such as primary and secondary database names, time since last backup, last backup file, last restore file, etc...
* sp_help_log_shipping_monitor_primary
o returns all columns from the log_shipping_monitor_primary table for the specified primary log shipping database. It returns server name, database name, time of last backup, backup threshold, threshold alert and history retention period.
* sp_help_log_shipping_monitor_secondary
o returns all columns from log_shipping_monitor_secondary table for the specified secondary log shipping database. It will return database name, server name, restore threshold, last copied file, time of last copy / restore and history retention period.
** select * from msdb..restorehistory where destination_database_Name like '%capitalone%'
order by restore_history_id desc
** sp_tables
** select * from mediafamily where restore_history_id=''

-- Also look at high sustained Other Process CPU Utilization values
24. To find out How much % backup completed : (compltion tab)
=============================================================
1. select * from sys.dm_exec_requests
25. Obtaining information about the top five queries by average CPU time :

['database name'|database id], -- can be the actual name or id of the database
file number, -- the file number where the page is found
page number, -- the page number within the file
print option = [0|1|2|3] -- display option; each option provides differing levels of information
)
ex:
=====
-- List data and index pages allocated to the EMPLOYEE table
DBCC IND('MSSQLTIPS',EMPLOYEE,-1)
GO
27.How to Update Statistics
===========================
There are two ways to update statistics. The first way is the easy way. It is one line of code that will update all the statistics in the database using the default sample size of 20,000 rows per table.
EXEC sp_updatestats
The other way, is to use the UPDATE STATISTICS command. This command gives much better granularity of control:
-- Update all statistics on a table
UPDATE STATISTICS Sales.SalesOrderDetail
-- Update a specific index on a table
UPDATE STATISTICS Sales.SalesOrderDetail IX_SalesOrderDetail
-- Update one column on a table specifying sample size
UPDATE STATISTICS Production.Product(Products) WITH SAMPLE 50 PERCENT
Using update statistics can give you the granularity of control to only update the out of date statistics, thus having less impact on your production system.
28.To find long running queries in sql server :
===========================================
SELECT TOP 100 qs.total_elapsed_time / qs.execution_count / 1000000.0 AS average_seconds,

o.name AS object_name, DB_NAME(qt.dbid) AS database_name FROM sys.dm_exec_query_stats qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) as qt
LEFT OUTER JOIN sys.objects o ON qt.objectid = o.object_id
where qt.dbid = DB_ID()
ORDER BY average_seconds DESC;

– determine the nodes on a SQL Server clustered server instance:
SELECT * FROM sys.dm_os_cluster_nodes

39.Blocking information
============================
Blocking in SQL Server is a scenario where one connection to SQL Server locks one or more records, and a second connection to SQL Server requires a conflicting lock type on the record or records locked by the first connection. This causes the second connection to wait until the first connection releases its locks. By default, a connection will wait an unlimited amount of time for the blocking lock to go away.
In real time scenario blocking is something that can't be avoided needs to be looked upon when it occurs.
40.To find the Snapshot isolation is off or on

-----------Uninstalling SQL 2005 Manually----------
First, here are the recommended steps to manually uninstall SQL 2005:
http://support.microsoft.com/kb/909967
If that doesn't work, this is how you can manually uninstall all versions of SQL 2005 so that SQL can be reinstalled:
Note – This method will delete all databases and configuration, you must have a backup of your existing SQL databases (which this uninstall will delete) before proceeding. (Again, this is not supported, please call Microsoft PSS for supported methods)
Uninstall all SQL components possible in Add/Remove Programs (including the SQL client and VSS writer)
Stop all SQL Services and configure them to disabled using Start > SQL Configuration Manager
Delete the following registry to get rid of the services. If you have multiple instance installed, it will be Keyname$Instance (i.e. MSSQLServer$OFFICESERVERS)
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSSQLServer
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSQLServerAgent
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSSQLServerADHelper
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesReportServer
Verify that the services do not exist in the SQL Configuration Manager.
Delete the SQL Configuration in the registry
HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSSQLServer
HKEY_LOCAL_MACHINESoftwareMicrosoftMicrosoft SQL Server
Note – if you installed a 32 bit version of SQL on 64 bit version of Windows, you will need to also delete them from the 32 bit registry node that is redirected. More Info MS 896459.
* HKEY_LOCAL_MACHINESOFTWAREWOW6432nodeMicrosoftMSSQLServer
* HKEY_LOCAL_MACHINESOFTWAREWOW6432nodeMicrosoftMicrosoft SQL Server
Delete the SQL Program files – Note this will also delete the existing databases on the system that must be restored from backup.
Delete the directory: C:Program FilesMicrosoft SQL Server
Note – if you installed a 32 bit version of SQL on 64 bit version of Windows, you will need to also delete them from the 32 bit program files:
C:Program Files (x86)Microsoft SQL Server
You might need to reboot to close all files before you can delete the directory.
