When an underlying hardware or connectivity issue disrupts the storage fabric, the ASM Health Checker works in tandem with the Rebalance ( RBAL ) and Group Monitor ( GMON ) background processes. The process typically unfolds across four technical milestones: 1. Persistent Storage Timeout
Once the underlying physical or logical fault is resolved, update the health check registry. Run a manual cluster check with orachk -u or exachk -u . asm health checker found 1 new failures updated
If you are an Oracle Database Administrator (DBA) managing an Oracle Real Application Clusters (RAC) environment, you have likely encountered a cryptic but critical message in your alert logs or monitoring console:
The health checker might run many times successfully, but a previously latent corruption (for example, a block that was never read) becomes discovered. In this case, the message “found 1 new failures” may be the first indication of a problem that has existed for weeks. ALTER DISKGROUP data CHECK ALL; When an underlying
To proactively detect such issues, Oracle includes a diagnostic framework known as . For ASM, this manifests as the ASM Health Checker —a set of low‑level diagnostic routines that run automatically in the background. These health checks validate various layers of the ASM instance, including:
For automated assistance, you can use tools like Oracle ORAchk to run a comprehensive health check on your entire Oracle stack. Run a manual cluster check with orachk -u or exachk -u
Schedule weekly manual checks using:
ASM Health Checker is a vital tool for database administrators, as it helps ensure the reliability, performance, and security of the database. By regularly checking ASM's health, administrators can detect potential issues before they become critical problems, minimizing downtime and data loss. ASM Health Checker monitors various aspects of ASM, including disk availability, space usage, and data consistency. This proactive approach enables administrators to take corrective actions, maintaining optimal database performance and security.
