Alejandro Cobar is a SQL Server Database Administrator from Guatemala City. I am currently responsible for Production, QA and Development SQL Server Environments to make sure they are constantly performing as expected.
Alejandro has been a Microsoft Certified Professional since 2017, by passing the 70-462 exam. Before 2018 is over, Iím planning to achieve the MCSA in 2016 SQL Database Administration.
I focus on the following aspects of SQL Server:
- Guide the customer with the best alternatives and practices when new SQL Server deployments are required.
- Install and configure all supported versions of SQL Server and components.
- Install, configure and maintain High Availability/DR solutions.
- Plan, test, and deploy service pack installations and version upgrades.
- Design, implement, and support backup and recovery plans including scripting and scheduling.
- Migration of databases, database objects, and users.
- Databases refresh on Dev/Test/QA environments.
- Participate in DR drills exercises.
- Provide expert diagnostic analysis and resolution for all database operational problems that arise.
- Performance tuning and query optimization for large production environments.
- SQL Server DBA workbook creation and maintenance, including up to date procedures and how-to.
- Deployment of custom crafted scripts to monitor specific areas of the environment under my support (backups, mirroring status, always on availability groups status, disk drives usage, resources utilization by the SQL Server process).
