Schedule routine CHECK ALL executions during off-peak maintenance windows to uncover hidden media corruptions early.
When it prints found 1 new failures , it means a single, distinct event has degraded the cluster's idealized state. Common Root Causes Behind the Failure Alert
-- 2. From the output, note the NAME of the relevant health check run (e.g., 'HM_RUN_123') -- 3. Generate the detailed report for that specific run SET LONG 100000 LONGCHUNKSIZE 1000 LINESIZE 512 SELECT DBMS_HM.GET_RUN_REPORT('HM_RUN_123') FROM DUAL;
Thorough documentation is a cornerstone of effective system management. Record the following details in your team's knowledge base or ticketing system: asm health checker found 1 new failures
To identify and resolve the specific failure, follow these steps: ASM Generic Archives | Helmut's RAC / JEE Blog

Troubleshooting "ASM Health Checker Found 1 New Failures" Oracle Automatic Storage Management (ASM) is the backbone of storage management for Oracle Databases. When Oracle Grid Infrastructure generates an alert stating it means the internal ASM Health Checker (AMHC) framework has detected a specific vulnerability, corruption, or performance degradation within your storage tier.
As with many complex systems, proactive prevention is far better than reactive repair. Implementing the following best practices can significantly reduce the likelihood of encountering this alert: When Oracle Grid Infrastructure generates an alert stating
:Use the ADR Command Interpreter (ADRCI) to list the details of the specific failure. adrci> list failure Use code with caution. Copied to clipboard
:Locate the log file (usually in the trace directory of your Oracle Base) to see the events leading up to the "1 new failure" message. Look for: ORA-15xxx errors (ASM-specific).
