Disable the fault monitor processes:
1) Log on as root.
2) Locate where the db2fmcu command runs from by issuing the command: “ps -ef”

For example, on AIX the db2fmcu command is run from DB2DIR/bin directory, where DB2DIR is the location where the DB2 copy is installed.
Switch to the directory indicated by the ps command.
Disable the Fault Monitor Coordinator (FMC) by issuing the command: db2fmcu -d
ie
To prevent the fault monitor controller from being launched at system startup, run the following command “./db2fmcu -d”

Since there is only one Fault Monitor Coordinator, this step affects all DB2 copies on the system.

=============================================================
To stop the Fault Monitor Daemon
=============================================================
Issue the command: DB2DIR/bin/db2fm -i iname -D
where DB2DIR is the location where the DB2 copy is installed and iname represents the instance owner name.
