SQL Performance Monitoring & 6 Other Top Basic DBA Skills

As time passes, human resources are rapidly getting replaced by computing resources, affecting the task range of an Oracle DBA. You may have observed the consolidation of Oracle instances onto a bigger server with a greater number of CPUs. Due to this, fewer DBA professionals are needed by organizations. 

At the same time, a DBAs list of tasks keeps increasing since the same set of activities needs to be completed by fewer staff. From schema design handling to SQL performance monitoring, there are many essential database management duties assigned to surviving DBAs. On the bright side, Oracle DBAs no longer have to perform tedious tasks such as implementing patches on several servers and perpetually re-assigning server resources. re-allocating server resources, and t
uning many servers.

6 Most Important Skills for a Database Administrator

Since a professional Oracle DBA is generally brought into crucial IT department undertakings, authorities may often give preference to professionals with a wider range of both Oracle-based and non-Oracle-based job skills.

While the applicants usually have all the Oracle-based skills gained in academic Information Technology and Computer Science courses, they may or may not have some of the Non-Oracle job skills, including the following:

• Database Design – Numerous projects need an understanding of concepts such as data modeling methods, database normalization, and STAR schema.

• System Analysis – Oracle specialists often end up playing an important part in designing and analyzing new DBMSs. Therefore, they should be aware of concepts such as DFDs (data flow diagrams), CASE tools, methodologies in entity-relation shaping, and data dictionary techniques.

• 
  Change Control Management – Aside from knowing how to performance tune SQL query, the candidate should know how to implement change control as they are likely to be handed over that responsibility. They also must be able to make sure those changes are sufficiently carried out to the production database aside from knowing about the third-party change control resources such as the UNIX Source Code Control System (SCCS).

• Physical Disk Storing – They need to have knowledge of RAID, cache controllers, disk hardware architecture, and disk load balancing.

• Backup and Recovery – Since a majority of projects use third-party backup and recovery technologies, the DBA requires proper experience implementing these methods.

• 
  
  Data Security skills – Excellent knowledge of MySQL SQL performance tuning and how to implement database security measures in RDBMS, especially role-based security is quite useful.

Conclusion

Many Oracle users and specialists wrongly believe that a database administrator in Oracle only needs to have technical skills such as how to performance tune SQL query. However, the Oracle DBA needs to have a much broader range of skills as they not only have the responsibility of the design but also various other elements of the database such as implementation, storage, and data recovery. 

Therefore, they require good technical and communication skills to handle all the different aspects of database management in the best way possible and keep operations streamlined among all these areas.
