PostgreSQL 9 Database Administration and Deployment

+ View more dates & times
  • Overview

    This PostgreSQL 9 Database Administration and Deployment course covers PostgreSQL database administration and planning for a production deployment with multiple servers. Hands-on workshop exercises are provided for performance and replication fundamentals. The class will also introduce techniques and tools for managing servers as they grow over time. The course workshop will set up a replicated pair of PostgreSQL on Linux databases to have the same content, using the database’s built-in replication. Test data will be installed on the workshop systems to demonstrate query performance troubleshooting. The tools used will be based on the command line interface to the database. Other High-Availability and multi-node scaling architectures will also be introduced and compared. Some examples of larger web or GUI management tools will be shown. The focus of the class is learning how to evaluate and compare the major options for tools and replication, not specifically on how to use any one of them. The examples target PostgreSQL versions 9.1 and later. Students are encouraged to ask questions about features the instructor can demonstrate at any time.

    Upon completing this course, students will be able to:

    • Setup a test environment with sample data
    • Monitor database activity and statistics
    • Understand what background maintenance the database does automatically
    • Look for problems in the server’s log files
    • Setup the server postgresql.conf for a production system
    • Read the output of a query plan
    • Monitor which queries are using up the most server resources
    • Evaluate tools for analyzing the server’s workload
    • Add and remove table indexes based on a production workload
    • Deploy a high-availability standby replica
    • Monitor whether a replica is keeping up with the master’s traffic
    • Outline architectures for scaling PostgreSQL servers across multiple nodes
    • Look for queries that are stuck or locking excessively
    • Evaluate tools for server monitoring and problem alerting
  • Who Should Take This Course
