This is one of the most common error searched on my blog search https://blog.sqlauthority.com/search-sqlauthority/ and lately I realized that I have not written any blog about the cause of such error and fixing that. Let us learn about how to fix the error login failed.
Here is the situation which my client explained and I was asked for help about SQL Cluster Resource.
Hi Pinal,
We are having 2 node windows cluster having 3 SQL Server instances clustered running on Windows 2012 R2 on VMware. We have one instance that will start from the services.msc but not from the Failover Cluster Manager when attempting to bring the service online. In reality the services start because during the ‘Online pending’ I am able to connect and query the databases on that instance, although it is in the ‘Online pending’ state.
Do you know what could be the problem?
[Note from Pinal]: This is a new episode of Notes from the Field series. When we build an application, we build it with zeal and enthusiasm. We believe it will do well for many years but it is not the case always. After a while performance started to go down and everything is not in the best shape. This is the time when we need to monitor performance and take action based on our analysis.
The journey for IT started way back in my college days more than a decade back. It was a booming time and it was exciting to see everyone eyeing the Computer Science stream. Almost every other person in those days always wanted to take this new trend. Riding the waves was one part of excitement, while the other was to be unique in whatever we do. It is easy to get stereotyped with someone and we can never be different from the herd. I always believed in doing the basics right – this blog project that I started more than 8 years was to bring these basic learnings back. I am glad I have been doing this. Let us learn about Write Ahead Logging.
