When you logon to MyOracle Support, you will find it simply in the alert section to the left. On Jan 25, 2023, this Important alert for Oracle Database and GI RU 19.18.0 on Linux has been released. Due to an issue described in MOS Note: 2923428.1 – LMON trace file with repeated entries of “Submitting asynchronized dump request” the Release Updates (RU) 19.18.0 for the Oracle Database and Grid Infrastructure on Linux have been removed from the download section temporarily.

Now, you can’t able to download the 19.18 Software from MOS if you have already download then don’t apply it. Perhaps If you have already download and applied then Oracle Given Work Around to disable LMON tracing.

Furthermore, MOS Note: 2923428.1 – LMON trace file with repeated entries of “Submitting asynchronized dump request” describes clear workarounds.

Either execute on all instances:

alter system set events=”trace[KJZD] { process: pname=LMON } disk=disable”;

or place this event and the below underscore directly into your init.ora/spfile on all instances:

event=”trace[KJZD] { process: pname=LMON } disk=disable”

_diag_dump_request_debug_level=0

The idea of rebooting the node before 48 days are reached may be not realistic I’d guess.
