In large establishments, where there are many servers, there are always chances of some servers or databases not being used but which remain operational. There is a need to decommission those servers or databases so that they can be used for other purposes. This should be a continuous process to analyze servers or databases which are not in use. There is huge cost of storage and licensing which an organization can save by reusing them. Before deciding to decommission such servers or databases you need to ensure they are not used by any app or user. This needs to be tracked but it’s not always easy. There are times when a db is put in offline mode and the DBA team waits for someone to raise an alarm that they are not able to connect to them for whatever purpose, then those databases are brought online. This approach has many flaws; app becomes unavailable, causes inconvenience to teams using them and creates downtime. Thus there needs to be a more proactive approach to analyze first before we decide to decommission a server or database. In order to accomplish this, you have created a job which will capture usage of all databases along with logins using them and hostname from where connections are coming. This information is captured in a table. You can let this job run for a week or two and then see who all are connecting to which database and decide or check whether to decommission them or not. You can run ‘select * from DBAdmin..loginaudit’ to see the info captured Following code is for SQL Server 2005 and above -------------------------Create a Table in DBAdmin
