Duration
14 hours (usually 2 days including breaks)
Requirements
Basics of an operating system administration.
Overview
This course covers everything a database administrator needs to know to successfully deploy and maintain MongoDB databases.
Diagnosing performance issues, importing and exporting data, and establishing the proper backup and restore routines, overview of the MongoDB CRUD API, the command shell, and the drivers are also covered.
The audience of this course include people who want to:
- Understand MongoDB from a developer’s perspective, including its command shell, query API, and driver tools.
- Deploy MongoDB in all its configurations – as a single server, with master/slave replication, as a replica set, and as a sharded cluster.
- Evaluate applications and choose hardware appropriately.
- Monitor MongoDB instances and integrate with standard monitoring software (Munin, Nagios, etc.)
- Plan for backups and manage large data imports and exports.
- Troubleshoot the most common developer issues and failure scenarios.
Each delegate will need to perform a series of practical exercises.
