A structured approach is essential. Do not panic. Follow the diagnostic pathway that matches your environment.
When this message occurs, it indicates that a health check—either triggered automatically by an incident or run manually—has identified a problem that could compromise your storage. Common triggers include:
:
Look for timestamps matching the alert notification. The log will map the "1 new failure" to a specific error code (such as ORA-15032 , ORA-15078 , or ORA-15130 ). Use the ASMCMD Health Check Command
Note: If "ASM" in your context refers to Oracle Automatic Storage Management, the focus of this write-up should shift immediately to Disk Group redundancy, ASM instance connectivity, and I/O latency checks. asm health checker found 1 new failures
Follow this structured approach to isolate and remediate the failure. 1. Identify the Failing Secret and Timestamp
The ASM Health Checker is a background process that periodically checks the health of the ASM infrastructure. It monitors various aspects of ASM, including: A structured approach is essential
A healthy ASM is the silent foundation of a robust Oracle database. Listen to its health checker, and your database will thank you with uptime.
When the checker finds a failure, it logs the alert. Many users report seeing "ASM Health Checker found 1 new failures" appear in the alert log file ( log.xml ) or as a metric alert in Oracle Enterprise Manager (OEM). When this message occurs, it indicates that a
Run the health checker in verbose mode to identify exactly which assertion failed.
