FAQPage Schema

How does InterSystems IRIS mirroring handle automatic failover for high availability?▼

InterSystems IRIS mirroring handles automatic failover by using components like the ISCAgent and Arbiter to monitor instance health. When a primary node fails, these components coordinate to safely switch operations to a synchronized backup, ensuring rapid system uptime recovery.

What are the requirements for safe automatic failover in InterSystems IRIS?▼

Safe automatic failover in InterSystems IRIS requires proper configuration of the Arbiter and ISCAgent to prevent split-brain scenarios. You must also ensure continuous mirror synchronization and maintain disk redundancy to guarantee data integrity during the transition.

What is the best way to ensure high availability and disaster recovery for InterSystems IRIS?▼

The best way to ensure high availability and disaster recovery for InterSystems IRIS involves configuring failover clusters, virtualization HA, or InterSystems IRIS mirroring. Combining these strategies with journaling and regular backups guarantees maximum system uptime and data integrity.

Does InterSystems IRIS support virtualization HA for disaster recovery?▼

InterSystems IRIS does support virtualization HA as a strategy for disaster recovery. This approach works alongside failover clusters and native mirroring to provide an additional layer of protection against server failures, ensuring continuous system operation.

Why is mirror synchronization important for InterSystems IRIS high availability?▼

Mirror synchronization is important because it ensures the backup member accurately replicates all data changes from the primary. This continuous data replication guarantees that when automatic failover occurs, the backup system is ready to serve users without data loss.

When should I use InterSystems IRIS mirroring instead of traditional failover clusters?▼

You should use InterSystems IRIS mirroring when you need automatic failover with strict data integrity guarantees across geographically distributed environments. Unlike traditional clusters, mirroring utilizes the ISCAgent and Arbiter to safely manage instance-level failures.
