By Josh Patterson | July 11, 2019 | 0 Comments

Today I want to talk about one of my favorite tricks that’s not talked about much: mapping a network drive under the SQL Server account. You see, mapped drives are “per user” – so if you map one on the SQL server, then SQL server can’t see it. Likewise, if you map one for SQL…

Enable and Disable xp_cmdshell

xp_cmdshell is one of those somewhat hidden gems/power-tools in SQL Server that can both make life easy and very insecure all at the same time. You see, this function allows any SQL Server administrator to run any command/program/shell-script/batch-file that the SQL Server account has access to. It seems counter-intuitive at first but I’ve seen this…

Installing VPS on any server is a pretty straight forward process – and installing on a workgroup is no different. Active Directory domains are recommended for larger environments because they benefit from the centralized security management – but many website setups or corporate ERP packages rely on dedicated walled off sets of systems that may…

What are these ephemeral drives on my VM?

By Josh Patterson | February 6, 2019 | 0 Comments

Ephemeral drives are a bit of a hot topic when it comes to computing in the cloud.

We’ll start at the top by first…

First of all, if you are not familiar with ephemeral storage, then check out our previous post on the topic. SQL Server loves to use tempdb and believe it or not it’s not relegated solely to the types of queries you might think, such as ordering and grouping. It’s used by a whole world of…

When you want to trace or instrument SQL Server activity, whether it be for performance purposes, security, auditing, etc. – you really have two baked in methods.
