-- Lab1


0. Antes de começar, vamos no Virtual Box, disponibilizar mais nucleos da CPU para nossa VM e no SSMS verificar a configuração de memória para SQL SERVER e deixar pelo menos 2GB para Windows.

1. Abrir task manager e verificar uso de cpu, memoria e disco
2. abrir ssms e conectar base de dados StackOverflow2010
3. Executar :

    DBCC DROPCLEANBUFFERS  -- vamos limpar os dados que estao em cache. Nao faça isto em producao.
    DBCC FREEPROCCACHE
    GO 
    
   use StackOverflow2010
   go

   select * from [dbo].[Votes]
   go 10

4. Verificar uso de cpu e memória e disco
5. Rodar sys padroes do SQL SERVER e tentar descobrir o que está consumindo mais recursos
   sp_who2
   go
   sp_who
   go
6. Acessar http://whoisactive.com/
   Baixar a procedure e implantar em uma base de dados de apoio ou master

7  Executar :
   
   -- Ligar o Plano de Execuçáo Estimado e Atual Plano de Execução. 
   -- e ligar 
              SET STATISTICS IO ON 
              SET STATISTICS TIME ON

   -- Abrir task manager e verificar utilizacao cpu quando a consulta rodar e reparar o uso da cpu quando os dados aparecem na tela e sao carregados

    DBCC DROPCLEANBUFFERS  -- vamos limpar os dados que estao em cache. Nao faça isto em producao.
    DBCC FREEPROCCACHE
    GO
  
   select * from [dbo].[Votes] order by CreationDate desc

   -- Alterar nivel de paralelismo na configuração da instancia e colocar para rodar novamente. Verificar nivel de cpu e tempo de execucao.

    DBCC DROPCLEANBUFFERS  -- vamos limpar os dados que estao em cache. Nao faça isto em producao.
    DBCC FREEPROCCACHE
    GO
  
   select * from [dbo].[Votes] order by CreationDate desc

8. Rodar em outra aba sp_whoisactive e verificar se agora consegue identificar qual procedure estava a consumir mais recursos
   use master
   go
   sp_whoisactive

   - Abra 3 sessoes novas no querie e coloque para rodar ao mesmo tempo 
    select * from [dbo].[Votes] 
    go 10

   Verifique quais processos do sql server estáo sendo impactados com algum tipo de waits: 
    https://docs.microsoft.com/en-us/sql/relational-databases/system-dynamic-management-views/sys-dm-os-wait-stats-transact-sql?view=sql-server-ver15
    Veja a lista dos waits

    Através deste comando conseguirá ver os maiores waits desde ultimo sql server start
    select * from sys.dm_os_wait_stats 
    order by wait_time_ms desc

    Posso forçar e apagar a lista para realizar um teste novo e verificar se os problemas continuam apos alguma intervençao:
    DBCC SQLPERF ('sys.dm_os_wait_stats', CLEAR);  
    GO 

    Rodar novamente para ver os waits
    select * from sys.dm_os_wait_stats 
    order by wait_time_ms desc

   Verificar a sessão com maior peso e matar o processo, apenas em situacoes muito criticas para evitar parar o sql server:
   
   Kill Session_id

   obs> documentacao da sp_whoisactive 
        http://whoisactive.com/docs/

9. Vamos usar um outro ótimo procedimento que basicamente faz a mesma coisa que a whoisactive com alguns elementos a mais
   
   https://www.brentozar.com/archive/2017/10/get-live-query-plans-sp_blitzwho/    

   Executar :
   select * from [dbo].[Votes]
   go 10

   Em outra aba rodar: sp_BlitzWho e sp_blitzcache (ver o que está rodando com mais peso). Deixei o codigo sp_blitzcache no final deste arquivo, mas o ideal é baixar do site abaixo:

 -- https://www.brentozar.com/blitzcache/

  -- Depois de rodar sp_blitzcache limpar os buffers e remover os 
  -- planos do cache e rodar novamente.

    use master
    go
    sp_BlitzCache
    go

    DBCC DROPCLEANBUFFERS  -- vamos limpar os dados que estao em cache. Nao faça isto em producao.
    DBCC FREEPROCCACHE
    GO
    use StackOverflow2010
    go
    select top 1000 * from [dbo].[Votes] order by CreationDate
    go 10

  -- Parar a execucao antes do final e verificar se entrou no buffercache com 
     use master
     go
     sp_blitzcache

  -- e rodar novamente este codigo mais rapido 
    use StackOverflow2010
    go
    select top 100 * from [dbo].[Votes] order by CreationDate

   -- e verificar novamente 
   use master
   go
   sp_blitzcache

   -- e no sp_blitzcache retirar do cache apenas o comando select (coluna remove plan handle from cache)
   -- DBCC FREEPROCCACHE (....);
   -- e verificar novamente 
    use master
    go
    sp_blitzcache

    -- Vamos rodar agora este select e vamos verificar o total de leituras e o custo: 
    -- ligar actual execution plan e ligar estatisticas de leitura e tempo de cpu

    DBCC DROPCLEANBUFFERS  -- vamos limpar os dados que estao em cache. Nao faça isto em producao.
    DBCC FREEPROCCACHE
    GO
    set statistics io, time on
    use StackOverflow2010
    go
    select top 10 id from [dbo].[Votes] order by CreationDate -- vai primeiro ordenar toda a tabela por creationdate para depois pegar os 10 primeiros
   
    -- Rode novamente o mesmo comando sem limpar o cache. O tempo será o mesmo porque
    -- o SQL SERVER roda o mesmo comando. O que ele guarda no cache sao os planos que 
    -- o otimizador de queires usa, dados que ja estavam na memoria mas nao por exemplo
    -- a ordenacao, ou transformacoes dos dados, filtros de busca, etc 

     select top 10 id from [dbo].[Votes] order by CreationDate

    -- AINDA, NAO ADIANTA COLOCAR TOP e colocar um order by em uma tabela grande, 
    -- sem um indice, porque o SQL Server ira ler toda a tabela para depois limitar 
    -- em top x para demonstrar.

    -- Veja a quantidade de leituras feitas em numeros de paginas, e agora rede sem o order by.

    select top 10 id from [dbo].[Votes] -- Verifique o plano de execucao e o custo e veja quantidade de paginas de dados lidas e o tempo

  -- Agora crie um indice pelo SSMS, no campo creationdate e rode novamente:

    select top 10 id from [dbo].[Votes] order by CreationDate

   -- Verificar o plano de execucao que agora fez index scan em uma faixa de 10 registros 
   -- no novo indice criado e verificar a quantidade de leituras logicas realizadas
    
    -- ver indice criado 
	sp_helpindex votes

    -- deletar o indice novo criado 
    drop index [...] on votes

    -- ver indice criado pelo script e no SSMS, modo GUI.
	 sp_helpindex votes

    -- e rodar novamente o comando com order by e vera que o problema de leitura 
	-- excessiva e perda de performance retorna

    select top 10 id from [dbo].[Votes] order by CreationDate

    -- e agora vamos colocar um filtro
   select top 10 * from [dbo].[Votes] where postid = 999999
   order by CreationDate

   -- e vamos ver o resultado em termos de quantidade de leitura, o 
   -- tempo e o tipo de leitura feito no plano.

  -- Agora vamos criar um indice por este campo postid

  USE [StackOverflow2010]
  GO
  CREATE NONCLUSTERED INDEX [idxVotesPostid1]
  ON [dbo].[Votes] ([PostId])
  go

-- e vamos rodar novamente e verificar a quantidade de leitura e o plano utilizado

   select top 10 id, postid from [dbo].[Votes] where postid = 999999

-- e agora rode estes dois processos e veja a diferença e resposta porque apareceu operador Key Lookup?

   select top 10 id, postid from [dbo].[Votes] where postid = 999999
   order by CreationDate
   go

   select top 10 * from [dbo].[Votes] where postid = 999999
   go

-- vamos relembrar os principais status dos waits
   select * from [dbo].[Votes] 
   order by CreationDate
   WAITFOR DELAY '00:10';
   go 100

-- abra uma nova janela e roda 
use master
go
sp_whoisactive

-- Main Status (waits):

-- Running means just that, the process is on the CPU, currently working.
-- Pending means The session is waiting for a worker thread to become available.
-- Runnable means it's waiting to be scheduled on to the CPU.
-- Suspended means it's waiting for something (eg lock, latch, memory grant, etc)

-- Verificar o TASK MANAGER,  ACTIVY MONITOR DO SQL SERVER 

-- Verificar PERFMON 

--  https://docs.microsoft.com/en-us/azure/monitoring/infrastructure-health/vmhealth-windows/winserver-memory-pagespersec
--  https://www.poweradmin.com/blog/pages-per-second-counters/

--  Vamos ligar o Contador (pages/sec) e colocar para rodar um bloco abaixo de cada vez e verificar o contador

   select  Id, Age from [dbo].[users] 
   go 100

   select  Id, Age, AboutMe from [dbo].[users] -- qual a caracteristica do campo aboutme?
   go 100

 -- Se o contador PAGES/SEC mostrar consistentemente mais de 40 páginas por segundo em um disco lento ou 300 páginas por segundo em um disco rápido,
 -- você deve investigar. A memória do seu sistema pode estar muito pequena para a carga de processamento.
 -- você pode resolver esse problema simplesmente adicionando mais memória ao servidor ou pode ser por falta de indices, falta atualizacao das estatisticas
 -- ou por exemplo codigo sql mal feito por exemplo que esta fazendo o SQL SERVER
 -- ler mais dados do disco do que é necessário e trazer mais dados para memória e assim retirar outros dados que ja estavam na memória.

-- Outros contadores. Os numeros são sugestoes mas depende de cada ambiente e criticidade do ambiente

-- Lab2

-- 1 Vamos rodar estes 2 codigos em duas sessoes de forma paralela e verificar o que esta ocorrendo no sql server com sp_whoisactive em outra sessao e verificar o campo blocking_session_id

  set statistics time, io on 
  use StackOverflow2010 
  select  id, age from [dbo].[users]

  use StackOverflow2010 
  select  * from [dbo].[users]

-- 2 Agora abra uma nova sessao e rode este codigo e verifique os waits e a coluna blocing_session_id no sp_whoisactive
begin tran
UPDATE users  
SET Age = 18  

-- 3 Verifique se os selects ja terminaram de executar e ler todos os dados e abra uma nova janela com este codigo
  use StackOverflow2010 
  select  id, age from [dbo].[users] with (nolock)

-- 4 Agora va para a sessao onde terminou de rodar o update, e vamos simular que houve um erro no update e náo pode ser completado. Vamos execucar um rollback e logo depois vamos
-- rodar novamente o comando select  id, age from [dbo].[users] with (nolock)
--.Como ficou os dados que foram alterados para 18 mas nao confirmados com o commando implicito ou explicito commit?
-- O que aconteceria se naquele momento tivesse gerado um relatorio e entregue para sua diretoria ou cliente?
-- Antes verifique o sp_whoisactive quais processos que ainda estao rodando.

-- 5 Algumas opcoes do sp_whoisactive
http://whoisactive.com/docs/06_options/

 sp_whoisactive @help = 1

-- 6 Abrir uma nova sessao e rodar o codigo
  use StackOverflow2010 
  select  * from [dbo].[users] order by aboutme
  option (maxdop 0) -- com este maxdop ira utilizar todos os nucleos da cpu, mesmo que em nivel de instancia esteja marcado para nao fazer procesamento paralelo em max degree os paralelism
                    -- se um determinado processo estiver rodando com processamento em paralelo e gerando problemas de perda de performance recebera o wait CXPACKET no sp_whoisactive
  go 100

-- abrir uma nova sessao e rodar o sp_whoisactive com o parametro para ver o plan de execucao
use master
go
sp_whoisactive @get_plans = 1 -- this gives you the execution plans for running queries.


-- 7 Abrir a sessao do update e rodar novamente
use StackOverflow2010 
select  * from [dbo].[users] order by aboutme
go 10

-- abrir uma nova sessao e rodar
sp_whoisactive @get_locks = 1  –- gives you an XML snippet you can click on to see what table, row, object, etc locks each query owns. Useful when you’re trying to figure out why one query is blocking others.
-- Verificar a coluna locks

-- 8 Agora rodar este comando

begin tran
UPDATE users  
SET Age = 18  

-- e uma nova sessao verificar a coluna lock
sp_whoisactive @get_locks = 1 – gives you an XML snippet you can click on to see what table, row, object, etc locks each query owns. Useful when you’re trying to figure out why one query is blocking others.

	This script displays your most resource-intensive queries from the plan cache,
	and points to ways you can tune these queries to make them faster.


	To learn more, visit http://FirstResponderKit.org where you can download new
	versions for free, watch training videos on how it works, get more info on
	the findings, contribute your own code, and more.

	Known limitations of this version:
	 - This query will not run on SQL Server 2005.
	 - SQL Server 2008 and 2008R2 have a bug in trigger stats, so that output is
	   excluded by default.
	 - @IgnoreQueryHashes and @OnlyQueryHashes require a CSV list of hashes
	   with no spaces between the hash values.

	Unknown limitations of this version:
	 - May or may not be vulnerable to the wick effect.

	Changes - for the full list of improvements and fixes in this version, see:
