seeking information on diskmon
Oracle SE-One 11.2.0.1Oracle GI 11.2.0.2
Oracle Linux 5.6 x86-64
ASM is standalone, no RAC involved at all
Last week I upgraded my GI from 11.2.0.1 to 11.2.0.2 and over the next few days notice a constant increase in disk usage on the mount point containing ORACLE_HOME. Tracked it down to a bunch of core dumps in ORACLE_HOME/log/<server>/diskmon. Research led to MOS note [1337867.1] and a couple of related bugs. Turns out that there are two diskmon processes running. One since the upgrade, the other dies and restarts every 10 minutes, throwing a new dump in the process.
The fix is simple enough, just kill the older of the two processes. I've tested that on my sandbox and it seems clean enough. But I'd like to expand my understanding at this point.
