What would happen if your DBA went away? This scenario is more likely than you may think. Your DBA could go away — on vacation, fall ill, or simply accept another job. Given the critical nature of this role to the stability of core IT services, the business must have contingency plans to de-risk this scenario.
Steps to mitigate the situation
You can’t prevent your DBA from moving on to another job; instead you have to plan for it. What you can do is to minimize the business impact. Here are some suggestions:
- Make sure that database backup and restore procedures are well established and the backups are reliable. Test backups by simulating restoration of production databases in a variety of possible situations.
- Deploy 24×7 monitoring tools that help you watch not only server metrics like memory, disk, and CPU, but database metrics that give insight to the database performance and health. There are a variety of commercial tools available and sometimes a DBA will need to develop a custom script to ensure monitoring of all critical IT services.
- Create a disaster recovery plan and ensure that all the artifacts and relevant information are available to everyone.
- Make sure that procedures are not just verbally explained but communicated in writing. Documentation is the first step towards creating a productive and process-driven work culture.
- Stay current. Your operating system, virtual machine, and database version should all be “in-support” by the vendors. This is a best practice not only from a security standpoint but also a supportability standpoint. Modern systems have less outages than their predecessor versions.
Consider enlisting the support of remote DBA companies
This is an option to consider especially if you have a single point of failure in the DBA function. The option of leveraging a managed service is a popular choice because today’s business runs 24×7. A managed service company can either supplement your existing DBA, or provide a full DBA service, to give you a DBA function that is dependable and consistently meets SLAs.
