How to receive Deadlock information automatically via email.

http://www.sqlservercentral.com/articles/deadlock/71374/


Requirement number one:
The first requirement is to turn on the appropriate Trace Flags. We do that by running the following command.

DBCC TRACEON (3605,1204,1222,-1)

A brief overview to what those flags do is listed below.
3605 = write what we want to the error log.
1204 = Capture Deadlock Events.
1222 = Capture Deadlock Events with more info (SQL 2005 and higher)

It is important to note that setting trace flags this way will only work until the next time SQL Server is restarted. If you want to make sure your trace flags are always set this way, you can edit the startup options of SQL Server by using the -T switch or creating a SQL Agent job to run that code when the Agent starts.

Using SQL Profiler also can find the dead lock.

Grant all permissions on all tables,views

Grant select,insert,update,delete on all tables,views to Dev_Role on database

select 'grant select,insert,update,delete on '+ name + ' to Dev_Role' from sysobjects where type = 'U' or Type='V' GO

or
SELECT 'GRANT SELECT,insert,update,delete ON ' + TABLE_NAME + ' TO BATCH_ROLE' FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE'
Go

--Grant exec permissions for SP's
Grant execute privileges to all Stored procedures to Dev_Role role
select 'grant exec on '+ name + ' to Dev_Role' from sysobjects where type = 'P' AND category =0
Go

3. db_ddladmin – Create,alter,drop,truncate -?
The members of db_ddladmin database role can make any data definition language commands in the database.

Connection Pooling

Setting the maximum size of the connection pool is usefull if you suspect that you have blocking problems due to the large number of concurrent queries. In this case you may be able to reduce blocking by limiting the maximum size of the connection pool. Of course, the pool already limits the number of concurrent connections, so you may never encounter this problem.

Master database Transaction log backup can not take.

Only full database backups of master can be performed. Transactional log, differential or filegroup backups of master are not allowed. Thus if you create a Database Maintenance Plan for all the system databases or if you select the master database and you select the Back up the transaction log as part of the maintenance plan option, the backup transaction log step for the master database will fail with this error message:
