    1. COMP-13: The Weakest-Link in your High Availability system How to make sure your HA is really highly available

    2. COMP-13: The Weakest-Link in your High Availability system Goals To consider the entire system architecture for High Availability (HA). Provide a summary of all the fault tolerance features that provide HA. To think of possible disaster scenarios.

    3. COMP-13: The Weakest-Link in your High Availability system Agenda Your system chain Keeping your hardware protected Keeping your network connected DB availability Protecting WebSpeed and AppServer tiers Sonic fault tolerance features

    4. COMP-13: The Weakest-Link in your High Availability system Your system chain The strength of a computer system is based on its weakest link, much like a chain. Goal: to remove all of the single points of failure for an application.

    5. COMP-13: The Weakest-Link in your High Availability system Your system chain

    6. COMP-13: The Weakest-Link in your High Availability system Your system chain It is necessary to provide redundancy

    7. COMP-13: The Weakest-Link in your High Availability system Agenda Your system chain Keeping your hardware protected Keeping your network connected DB availability Protecting WebSpeed and AppServer tiers Sonic fault tolerance features

    8. COMP-13: The Weakest-Link in your High Availability system Keeping your hardware protected

    9. COMP-13: The Weakest-Link in your High Availability system Keeping your hardware protected Hardware Storage Devices RAID, Remote data replication device CPU Cluster hardware Facilities Air conditioning Fire and flood protection Power Source UPS, Power Plant, Alternative Power Supplies Alternate site

    10. COMP-13: The Weakest-Link in your High Availability system Keeping your hardware protected RAID (redundant array of independent disks) Striping (provides load balancing) Mirrored configurations (for increased reliability)

    11. COMP-13: The Weakest-Link in your High Availability system Keeping your hardware protected HA Cluster

    12. COMP-13: The Weakest-Link in your High Availability system Keeping your hardware protected Cluster

    13. COMP-13: The Weakest-Link in your High Availability system Agenda Your system chain Keeping your hardware protected Keeping your network connected DB availability Protecting WebSpeed and AppServer tiers Sonic fault tolerance features

    14. COMP-13: The Weakest-Link in your High Availability system Keeping your network connected

    15. COMP-13: The Weakest-Link in your High Availability system Keeping your network connected Network Alternate network paths Redundant network links Configure a Domain Name Server (DNS)

    16. COMP-13: The Weakest-Link in your High Availability system Keeping your network connected If using alternate site Use a virtual DNS entry for Your DB server Application server Web servers Programs File Server Hostnames should be virtual names Consider user VPN access for emergencies

    17. COMP-13: The Weakest-Link in your High Availability system Agenda Your system chain Keeping your hardware protected Keeping your network connected DB availability Protecting WebSpeed and AppServer tiers Sonic fault tolerance features

    18. COMP-13: The Weakest-Link in your High Availability system DB availability

    19. COMP-13: The Weakest-Link in your High Availability system DB availability Cluster configuration Protects from hardware failure Quick recovery time Easy to register DB once the cluster has been configured. OpenEdge cluster support Included with the Enterprise RDBMS Allows use of the procluster command to: register the DB with the cluster manager disable DB registration start and stop the DB query the status of the DB

    20. COMP-13: The Weakest-Link in your High Availability system Vendor specific cluster commands DB availability

    21. COMP-13: The Weakest-Link in your High Availability system DB availability OE provides a common interface For different cluster products. To integrate OE commands into the cluster environment.

    22. COMP-13: The Weakest-Link in your High Availability system DB availability OpenEdge DB replication Protects from storage problems Site fault tolerance protection Can be manually activated
