Hi,
I have recently installed and configured Oracle RAC 12c R2 on Redhat Enterprise Linux 7.3 (maipo) and I see that some how the Automatic Database Diagnostic Monitor got enabled on the RAC as notice gdb processes enabled on RAC processes like ohasd.bin and crsd,bin.
[root@oracle-proxy ~]# ps -ef | grep gdb
root 20671 1 30 04:40 ? 00:00:06 /usr/bin/gdb --quiet -nx /proc/2677/exe 2677

This is causing issues on the server as the gdb processes are CPU and memory intensive draining the server of it's resources.
Is there any way to disable this feature please?
