Guidance Required for OpenEdge Replication Plus Implementation and Automatic Failover

Hello Team,

We are planning to implement OpenEdge Replication Plus to reduce downtime and keep the application available 24x7 using automatic failover from Primary DB to Secondary DB.

We would like clarification on the below points:

  • What are the implementation steps for OE Replication Plus?
  • What configuration changes are required at DB/server level?
  • Do we need any application/code changes from our side for failover handling or reconnect?
  • Is Load Balancer / VIP mandatory for seamless failover?
  • What are the main dependencies and feasibility considerations for this implementation?
  • Does OE Replication Plus alone handle automatic failover completely, or are additional tools/scripts required?
  • What are the best practices followed in production environments?
Also, if there are any:

  • Knowledge Base articles
  • Official documentation
  • HA architecture references
  • Replication Plus setup guides
please share the links.

Our main objective is to minimize downtime and ensure application availability during DB failure scenarios.

Thanks in advance.
 
I suggest you start with the following steps:
  • download the OpenEdge documentation set for your release of OpenEdge;
  • read the entire OpenEdge Replication user guide manual; some releases have several manuals on this subject;
  • determine your business requirements:
    • document the business capabilities or objectives you hope to achieve by implementing OpenEdge Replication Plus
    • have the business people document their requirements for RPO and RTO (they can Google it if they don't know those acronyms)
      • that is their decision to make, not the DBA's
    • document why automatic failover is deemed a necessity, and how you believe false positives will be prevented (e.g. an unwanted failover due to a temporary network glitch)
    • determine whether you will have one target database or two, what their business roles will be, and where they will reside
    • determine that you have the necessary budget: OpenEdge licenses, servers, storage, OSes, other required software, and annual maintenance fees for all of this.
As Tom indicated, what you are looking for could take hours to write up and is far beyond the scope of help you should expect for free on a forum.

Do your homework and then ask specific questions about the technology. People will generally be happy to help you with a specific problem, especially when you give some indication that you have tried to solve the problem yourself. Your post reads like your boss (or interviewer?) gave you a written assignment and you are trying to outsource your work to a forum.
