2 very solid reasons (there are others) that every DBA should be learning and using PowerShell:
1 – Its very useful for admin at the O/S level.
At my current client I am team lead of System and SQL Admins, along with doing any of the work that comes our way. This means we need to be able to manage the modest server farm we have. Its big enough that we can’t log onto every server every day, but small enough nobody wants to buy a proper monitoring toolset. So…PS to the rescue!
Read on for the other reason. I think the relatively poor Powershell tooling with SQL Server (with respect to other groups like Exchange) limited general acceptance, but they’ve made some big improvements over the past year and there are some sharp minds in the community working to make Powershell even more important for DBAs.
