2. Give owner as ‘sa’ or those who have permission to run job.

3. Then go to steps->Enter step name as ‘Monitoring database name’àSelect Type as ‘Transact SQL Script’ àSelect database as ‘Master’àCopy the commands available in the below box into Command square box in the job step.

CREATE TABLE #tbl_spwho2 (SPID VARCHAR(4),Status VARCHAR(30),Login VARCHAR(50),HostName VARCHAR(50),BlkBy VARCHAR(4),DBName VARCHAR(30),Command VARCHAR(100),CPUTime VARCHAR(15),DiskIO VARCHAR(15),LastBatch VARCHAR(50),ProgramName VARCHAR(100),SPID1 VARCHAR(4),RequestID INT)

INSERT INTO #tbl_spwho2 EXEC SP_WHO2

ALTER TABLE #tbl_spwho2 ADD ProcessInfo VARCHAR(4000)

DECLARE SELECT_SPID CURSOR FOR SELECT SPID FROM #tbl_spwho2

SET @spid = ''

OPEN SELECT_SPID
FETCH NEXT FROM SELECT_SPID
INTO …

Performance Tuning by creating index.

Lets take one stored procedure having 3 delete statements took 10 mins to complete execution.Customer asking to reduce the execution time.
Table size:2.5GB

As a DBA,What will we do?

1.First check for presence of index in the condidtional columns in the delete statements.

2.If no means,please create non-clustered index in the conditional coulmns in the tables available in the delete queries.

3.Then execute the stored procedure.

4.Now it will took 50seconds to finish execution.

5.Thats it.

Let us know for anyother ways?

How to backup database into less size using LiteSpeed query?

Use below script to back up the database ‘kumartest’.


exec master.dbo.xp_backup_database

@database = N'kumartest',

@compressionlevel = 1,

@filename = N'J:\SQLBackup\MSSQL\kumartest\kumartest_Full_201003041713.bak',

@init = 0,

@with = N'SKIP',

@with = N'STATS = 10'
GO


INITàspecifies that all backup sets should be overwritten, but preserves the media header. If INIT is specified, any existing backup set data on that device is overwritten.

SKIPàdisables the backup set expiration and name checking usually performed by the BACKUP statement to prevent overwrites of backup sets

STATS [= percentage] àDisplays a message each time another percentage completes, and is used to measure progress. If percentage is omitted, SQL Server displays a message after each 10 percent is completed.

Hope we will get compressed backups.
