How To Change a Database Setting For A Database In A Availability Group

I was in the middle of a deployment and found that the database in the AG had been configured with service_broker enabled. This setting shouldn't' have been enabled for the database and needed to be disabled. As i found, the setting can't be disabled for a database in a AG group. Following steps were followed to disable the service_broker setting for database.

1.) Removed the database from the AG group

USE [MASTER]; ALTER AVAILABILITY GROUP [] REMOVE DATABASE ;

FYI. By this time the rest of the replica's will be out of sync

2.) Change the service broker setting for the database

3.) Add the database to the AG group on the primary server

USE [MASTER]; ALTER AVAILABILITY GROUP [] ADD DATABASE ;

4.) Logged on to the secondary database, restored the transaction log from primary with Norecovery

5.) Add the secondary database to the AG group

USE [MASTER]; ALTER DATABASE SET HADR AVAILABILITY GROUP = [];

steps 4 and 5 can be followed for all the replicas in the AG group,

High Watermarks For Incremental Models in dbt

The last few months it’s all been dbt. Dbt is a transform and load tool which is provided by fishtown analytics. For those that have created incremental models in dbt would have found the simplicity and easiness of how it drives the workload. Depending on the target datastore, the incremental model workload implementation changes. But all that said, the question is, should the incremental model use high-watermark as part of the implementation. How incremental models work behind the scenes is the best place to start this investigation. And when it’s not obvious, the next best place is to investigate the log after an test incremental model execution and find the implementation. Following are the internal steps followed for a datastore that does not support the merge statements. This was observed in the dbt log. - As the first step, It will copy all the data to a temp table generated from the incremental execution. - It will then delete all the data from the base table th

Create a dacpac To Compare Schema Differences

It's been some time since i added anything to the blog and a lot has happened in the last few months. I have run into many number of challenging stuff at Xero and spread my self to learn new things. As a start i want to share a situation where I used a dacpac to compare the differences of a database schema's. - This involves of creating the two dacpacs for the different databases - Comparing the two dacpacs and generating a report to know the exact differences - Generate a script that would have all the changes How to generate a dacbpac The easiest way to create a dacpac for a database is through management studio ( right click on the databae --> task --> Extract data-tier-application). This will work under most cases but will error out when the database has difffrent settings. ie. if CDC is enabled To work around this blocker, you need to use command line to send the extra parameters. Bellow is the command used to generate the dacpac. "%ProgramFiles

How To Execute A SQL Job Remotely

One of the clients needed its users to remotely execute a SQL job and as usual I picked this up hoping for a quick brownie point. Sure enough there was a catch and there was something to learn. Executing the job through SQLCMD was a no-brainer but getting it to execute on the remote machine was bit of challenge. On the coding Front 1 1.) The bat file included the following code SQLCMD -S "[ServerName] " -E -Q "EXEC MSDB.dbo.sp_start_job @Job_Name = ' '[JobName]" 2 2.) The Individual users were given minimum permissions to execute the SQL job Ex. use msdb EXECUTE sp_addrolemember @rolename = 'SQLAgentOperatorRole', @membername = ' Domain\UserLogin ' At the client machine This took a fair bit of time till our sysadmin got me an empty VM machine. Thanks Michael G I’m just going to copy the exact instructions that I copied to OneNote and passed on
