Disallowing page allocations for database '' due to insufficient memory in the resource pool 'default'.

-

If you are getting bored, just go through SQL error logs to get interesting things. Just like I did it today. I was preparing for one blog post and while checking few things in error log I found one entry as below.

2022-11-03 13:50:05.080 spid12s      Disallowing page allocations for database 'trans_DB' due to insufficient memory in the resource pool 'default'. See 'http://go.microsoft.com/fwlink/?LinkId=510837' for more information.

To know more about this issue, I went through the link given in the log. Also, referred my favorites SQL blog authors. After some analysis I found that,

If you get the error message, Disallowing page allocations for database '*\<databaseName>*' due to insufficient memory in the resource pool '*\<resourcePoolName>*'. See 'https://go.microsoft.com/fwlink/?LinkId=330673' for more information. in the error log when the available physical memory is sufficient to allocate the page, it may be due to a disabled Resource Governor. When the Resource Governor is disabled MEMORYBROKER_FOR_RESERVE induces artificial memory pressure.

To resolve this you need to enable the Resource Governor.

Ref : Resolve Out Of Memory Issues - SQL Server | Microsoft Learn

As given in the documentation, I just enable resource governor as given below. After that this message never logged in SQL error logs.

What is DACPAC and how to use it?

Few days before someone asked me a question about DACPAC and BACPAC. To be honest I was really not aware of it and I replied that I have heard these terms for the first time. That person replied DACPAC is used for deploying and upgrading database objects. Even after the clear statement, my reply was like developers would answer this better. Even though DBAs are responsible for migration and deployments. After few days, I got a requirement to migrate database schema (Only Schema) to another instance. In such a case most of us would have used the traditional way to script out the database objects and run the script on another instance. But what if there are many objects? I was exploring the easiest way to migrate the objects and got to know about DAC. After reading about DAC, I felt very sorry myself that I was not aware of such a simplest way of migrating and deploying database objects. I went to my friends who are senior developers and asked this question. None of them was aware ...

DBAs should always be ready to face any kind of disaster in SQL environment. That doesn't matter whether it is PROD or Non- PROD.  Recently I have been asked regarding recovering the sysadmin password. I couldn't understand the question hence investigated more to understand actual problem. Then I came to know that there is one SQL Server for which admin login and password is lost. I was Like seriously ? How one can be that much of irresponsible? But rather than getting into that kind of discussion I quickly got ready to help the team.  In SQL Server there is a way to access SQL Instance without login. Lets check that out. Steps : 1) Open SQL Server Configuration  Manager. 2) Right click on SQL Server service and go to Properties. 3) Go to "Startup Parameters" Tab and Add -m.   This will Start the server in Single user mode.  4) Click Apply and Ok. This change would require Service restart.  5) Once Service is restarted then, open CMD as Administrator. ...
