Database Administrator TEMP
The Database Administrator (DBA) is primarily responsible for database and application server systems management, performance monitoring and tuning, database and application server capacity planning, and troubleshooting application problems for enterprise-wide and customer-specific databases. The DBA is responsible for providing technical and organizational leadership for the enterprise's database environments. The leadership role includes overseeing the development and organization of databases and the assessment and implementation of new database technologies. The DBA ensures that data remains consistent across all instances in the County, that data is clearly defined and documented, that appropriate County staff can readily access data in accordance with their established security roles, and that the data is fully protected through the published database backup/recovery plan and disaster recovery plan. The DBA works with the UNIX administrator and network administrators to configure and maintain the infrastructure which the databases and application servers run on. The DBA troubleshoots and assists in the correction of software performance, operations, and database connectivity problems. The DBA works closely with appropriate IT staff and Business Analysts to ensure that any DBA-managed database meets the customer's requirements for performance, data security, and data access. Application Server systems software management, upgrades, and patches are also the DBA's responsibility. The DBA may move application updates to the test and production environments.
