SQL Server 2005 Transactional Replication Agents

  • Article

SQL Server 2005 replication agents are configured optimally out of the box, but occasionally you might need to alter the default behavior by tweaking the agent's parameters. SQL Server 2005 exposes some parameters through graphical interface that were available only from command line or through agent job steps in previous releases. Baya Pavliashvili encourages you to learn the new options available with each replication agent and how to fine-tune these options for your applications.

Question of the Day

The Read Committed Snapshot Isolation behaviour

I am currently working with Sql Server 2022 and AdventureWorks database. First of all, let's set the "Read Committed Snapshot" to ON: 

use master;
go

alter database AdventureWorks set read_committed_snapshot on with no_wait;
go
Then, from Session 1, I execute the following code: 
--Session 1
use AdventureWorks;
go

create table ##t1 (id int, f1 varchar(10));
go

insert into ##t1 values (1, 'A');
From another session, called Session 2, I open a transaction and execute the following update: 
--Session 2
use AdventureWorks;
go

begin tran;
update ##t1 
set f1 = 'B'
where id = 1;
Now, going back to Session 1, what happens if I execute this statement? 
--Session 1
select f1
from ##t1
where id = 1;
