Running the oakcli orachk command on one of my ODA before starting applying a new patch bundle, I noticed the following warning
FAIL => ASM Audit file destination file count > 100,000
Indeed, despite a purge running daily, the number of audit files generated daily was exceeding 200.000.
This was due to the CHECK_INTERVAL=1 being set at the cluster level
crsctl stat res ora.asm -p|grep CHECK
Here is the solution to change it to 60 seconds
crsctl modify res ora.asm -attr "CHECK_INTERVAL=60" -unsupported
Make sure to specify the latest attribute to avoid the error CRS-4995 error.
