This is a second round about this post.
In the first part, I listed the top 8 “Personal Characteristics” of a DBA, to me and 7 other authors. Now, let’s do the same about the “Technical Characteristics”, or just “Skills”…
As I said in the first part of, it’s not an usual subject, so, identify and select these skills was not an easy task. Also as in the first part, I made my own list before the search. And I believe in something like that…
# Top 8 DBA Skills:
1) Database Architecture
Components, pools, events, basic flow and structure, reports, logs, traces, views, SQL concepts… In a nutshell, how to use a Database.
2) Logic and some Programming Skills
Basic programming skills/logic is needed. Programming best practices, techniques and logics base in, at least, 2 different paradigms.
3) Infrastructure Knowledge
Components that surround or are basic services to DB : Networks, Computer Architecture / processors , Storage , Application Server operation , etc.
4) Data Structs and Database Design/Modeling
After all, it’s what database means: understand about structure of objects, partitioning, indexes, statistics, transactions, data modeling, manipulation tools and data migration.
5) Solid SQL and PL/SQL
As a base of data, you must know where data is, how to get it, how to manipulate it efficiently and aligned with good development practices. Isn’t it?
6) Database and SQL Performance Tuning
Wide and the hardest to archive in my opinion. For archive excellence on it, you’ll need all items above. Database operating knowledge, their pools, optimizers, available resources, development/programming and SQL to find gaps in the code, and infrastructure knowledge to understand possible external interference in the functioning of the DB.
7) Security and Oracle Support Interacting
Knowing good patching management practices, how to apply them, techniques and strategies for patch, upgrade and migration, openness and interaction on SRs, navigation Metalink, seraching and understanding of bugs, backup/recovery (DRs) management, access and possible security gaps in infrastructure, systems, or credentials.
8) Knows the Environment / Applications
To know the main applications of the company where you are, it implementation language, some business rules, the environmental behavior, most normal events, peak hours, the operation of legacy applications, people, company practices and their major gaps is essential.
