Design failover as an application recovery operation
Robot HA is an IBM i data-replication and high-availability enquiry. A replicated dataset does not by itself establish that the business can switch service successfully. The project needs application dependencies, recovery objectives and the authority to decide when a switch is appropriate.
Inventory source and target systems, applications and external connections. Define acceptable data loss and outage targets with the business owner, then confirm what the proposed design can support. Identify configuration and access dependencies that may not be covered by a simple description of data replication.
Rehearse switch and switchback before accepting readiness
Confirm current platform, version and replication-scope requirements with the manufacturer. Review bandwidth, target readiness and operational monitoring. Use an approved test plan to validate data state, application access and the steps operators follow during a switch.
The exercise should also address returning to the normal arrangement. Record decisions, dependencies and unresolved issues rather than reporting only that replication is running. Handover should include runbooks, escalation, validation checks and the conditions requiring intervention. For UAE sites sharing a building, carrier or utility, consider common dependencies in the design rather than assuming two systems mean independent resilience. Hardware, network work and continuing HA management should be distinguished from the software entitlement.
Evidence to request for this scope
- Confirm supported source and target configurations and the data or objects included.
- Agree recovery objectives and demonstrate application validation during an authorised switch.
- Rehearse switchback, decision authority and the response to replication exceptions.
