Oracle Database Error ACFS-03118: Host Node Resolution Failure

📦 Oracle Database
📋

Description

This error indicates that Oracle Automatic Storage Management Cluster File System (ACFS) cannot determine the node number for a specified host. This typically occurs in a clustered environment when ACFS attempts to query Cluster Synchronization Services (CSS) or the Oracle Registry for host-to-node mappings, and the lookup fails. It prevents ACFS operations that rely on accurate node identification.

Known Causes

⚠️
CSS Service Unavailability or Misconfiguration
The Cluster Synchronization Services (CSS) daemon, critical for cluster node discovery and communication, is either down, unresponsive, or incorrectly configured on one or more nodes.
⚠️
Oracle Registry Corruption or Incorrect Entries
The Oracle Registry, part of Oracle Clusterware, may contain corrupted data or incorrect entries for host-to-node mappings, preventing ACFS from retrieving the necessary information.
⚠️
Network Connectivity Issues
Underlying network problems, such as incorrect network configuration or firewalls, are preventing communication between cluster nodes or with the CSS daemon, hindering host resolution.
