HA/DR Monitoring

SAP Adaptive Server Enterprise (ASE) High Availability and Disaster Recovery (HADR) system involves two ASE servers, one serving as the primary for transaction processing and the other as a standby with replicated databases.

For monitoring this setup, IT-Conductor's ASE HA/DR monitoring feature provides visibility into the primary and standby servers, along with the status of the HADR system, synchronization mode, and synchronization state.

In the event of a primary server failure and the promotion of the standby server to the primary role, IT-Conductor quickly identifies the new active primary server.

The servers are visually organized in a cluster grouping, distinguishing the standby server with an inactive status symbol, typically represented by a power icon. This enables teams to promptly identify the current state of the system and take necessary actions to ensure uninterrupted service.

Prerequisites

Configure ASE primary and secondary databases for monitoring before configuring HA/DR monitoring in IT-Conductor.
