Ensuring Smooth SSRS Subscriptions in an Always On Availability Group
SQL Server Reporting Services (SSRS) is a powerful tool for managing and delivering reports in an enterprise environment. When configuring SSRS within a SQL Server Always On Availability Group, it’s essential to take specific steps to ensure that SSRS subscriptions continue to function properly during failovers. This blog outlines the key actions required to maintain seamless SSRS operations in such a setup.
Enhancing Availability with SQL Server AlwaysOn Database-Level Health Detection
AlwaysOn Database-Level Health Detection is an optional configuration that enhances the resilience of availability group databases. It monitors database transactions and, if an issue is detected, can automatically trigger a failover to another replica. This proactive measure helps maintain application availability even in the event of hardware or I/O failures.
