Starting an RS secondary server for the first time
After you complete the hardware configuration of the RS secondary server, you are ready to start the RS secondary server and connect it to the primary server.
Converting an offline primary server to an RS secondary server
After a planned or unplanned failover of the primary server to an RS secondary server, you can convert the old primary server to an RS secondary server.
Delayed application of log records
To aid in disaster recovery scenarios, you can configure RS secondary servers to wait for a specified period of time before applying logs received from the primary server.
Flow control for remote standalone secondary servers
Flow control provides a way to limit log activity on the primary server so that remote standalone (RS) secondary servers in the cluster do not fall too far behind on processing transactions. Enabling flow control ensures that logs on RS secondary servers remain current if the servers are on a busy or intermittent network.
Shared disk secondary servers
Cluster administration
Connection management through the Connection Manager
Connection Managers can control automatic failover for high-availability clusters, monitor client connections and direct requests to appropriate database servers, act as proxy servers and handle client/server communication, and prioritize connections between application servers and the primary server of a high-availability cluster. Connection Managers support high-availability clusters, replicate sets, server sets, and grids.
Cluster failover, redirection, and restoration
To maintain availability, you must plan for the failover of primary servers, redirecting client connections from unavailable servers, and restoring the cluster to its original configuration after a failure.
Distributed data
Overview of automatic monitoring and corrective actions
You can use the SQL administration API, the Scheduler, and drill-down queries to manage automatic maintenance, monitoring, and administrative tasks.

InformixHQ is a modern web console for visualizing, monitoring, and managing your Informix server instances. It is purpose built for ease-of-use, scaling out, and optimizing DevOps needs. It provides critical performance management capabilities, monitoring how key performance metrics are changing over time and tracking how efficiently Informix is running your workload even when you’ve stepped away from your screen. Its monitoring system feeds directly into a customizable alerting system so you can be immediately alerted via email, Twilio, or PagerDuty whenever an issue occurs on one of your Informix database server instances. InformixHQ is designed to be scalable to efficiently manage and monitor as many Informix database server instances as you need. Moreover, it's a tool that can be shared by the DBAs, the app developers, the ops engineers, and management and accessed from any desktop, laptop, or mobile device. InformixHQ is the centralized hub for graphical monitoring, alerting, and administration of your Informix database servers.
