Oracle's Health Monitor records every automatic and manual health check. Use the V$HM_RUN view to confirm the execution of the health checker that triggered the alert and to get its specific run ID.
In a High Availability (HA) cluster, the health checker often fails if the security policies are out of sync between the active and standby units. Symptoms: "Sync failure" or "Generation ID mismatch."
This article provides a 360-degree breakdown of this alert: what triggers it, how to diagnose the root cause, step-by-step repair procedures, and long-term prevention strategies.
This command performs an in-depth analysis and actively attempts to repair any found corruption. Real-world examples confirm that executing this command effectively resolved the issue and cleared the alert. asm health checker found 1 new failures
When you see the alert, do not panic. Follow this systematic diagnostic procedure:
Before troubleshooting the error, understanding the tool is crucial. The ASM Health Checker is an automatic, background diagnostic framework introduced in Oracle Grid Infrastructure 11gR2 (enhanced in 12c and 19c). It runs periodically (typically every hour or on specific triggers) to validate:
• Failure: TLS certificate expiry < 7 days • Component: asm-gateway • First seen: 2026-04-12 10:15 UTC • Severity: HIGH • Previous status: pass → current: fail
: If the affected disk group contains critical files like the OCR, Voting files, or database data files, the associated Oracle instance or Clusterware may crash. Common Root Causes Lost Storage Connectivity Attribute 'compatible
If compatible.asm , compatible.rdbms , or compatible.advm values are set incorrectly relative to the GI version, the health checker will report advisories as failures.
Use the ASM Metadata Core Utility ( AMDU ) to print and inspect the corrupted blocks. If the disk group has redundancy, force a manual rebalance to reconstruct the corrupted data from surviving mirrors: ALTER DISKGROUP REBALANCE POWER 5; Use code with caution. 3. I/O Performance Degradation (Slow Disks)
Improper shutdown (e.g., shutdown abort on ASM) leaves ASM metadata in an inconsistent state. The next health check reveals failure.
A failure notification might refer to a problem with the WHM Security Advisor . Symptoms: "Sync failure" or "Generation ID mismatch
The ASM Health Checker is part of the broader . It runs periodic checks—and can be triggered manually—to assess the integrity of:
He dug deeper into the ASM logs. The health checker hadn't flagged a total crash; it had flagged a "Zombie Process" in the health-check script itself. A legacy script, written years ago by an engineer who had long since moved on, had timed out while trying to ping a decommissioned staging server.
