6 Common Administration Errors Made With Your SQL Server

6 Common Administration Errors Made With Your SQL Server

Your Structured Query Language (SQL) server is the easiest database to use today. This doesn’t mean it’s simple, though. There are still a lot of hurdles you have to overcome if you’re going to make the most of it. To help you to stop making mistakes, we’ve compiled a list of some of the most common mistakes made by SQL server administrators.

1. Space and IO Load

Your IO load is how much your database can handle at once. Think of it as the stress test. Without going into specifics, if you’re focusing on how much disc space you have you’re at risk of running out of resources due to a lack of IO load. This can lead to a reduction in efficiency and urgently needed upgrades.

2. Ignorance of Business

You gain a lot of information about errors and potential obstacles through looking at the context in which the server is used in. Learn about the business and how the server is used. Simply knowing how to control the server and respond to requests isn’t enough. Your lack of knowledge will soon become apparent when something goes wrong.

3. Method in the Madness

Once something goes wrong you should be able to refer to a guide to how to find the problem. If you have no stated methodology, there’s a high chance you’ll miss out on problems.

You should put together a PDF document for how everyone should go about diagnosing problems. Focus on the root of the issue, as opposed to the symptoms.

4. Sticking with the Defaults

A major loss of productivity comes from the options you choose. The defaults of an SQL server will get your server running and working. What it won’t do is optimise it for the business. You’re losing efficiency. For example, you could find your databases are constantly being manipulated through the auto-shrink default option.

5. SQL Injections

The SQL injection is the biggest threat on the Internet. It’s the most common hack, and we know about as much today about it as we did five years ago. You can defend against these hacks, but it’s up to you to do the preparation work.

It’s amazing how many administrators don’t know who has access to the server, how much of the server is exposed to a potential hacker, and what they should do in the event of a hack attack.

Again, craft a PDF document which only certain people have access to. Everyone should know how to react to the threat of SQL injection.

6. Backing Up Your Data

In the event the world collapses into oblivion and your server gets wrecked, your administrator needs to know how to get the data back. Every company should prepare a back-up of all their data.

The main problem is so many administrators never test these back-ups. They assume they’ll work. They should see if they work and what potential issues could arise in the future. Anyone can install a piece of back-up software. You’re employing an administrator to implement a bespoke solution which has been thoroughly tested.
