ora.evmd and ora.mdnsd fails to start when http_proxy is set to https://

Problem:

After setting http_proxy to https string (export http_proxy=https://test) and then stopping and starting CRS got the following error:

CRS-2883: Resource 'ora.evmd' failed during Clusterware stack start.
CRS-4406: Oracle High Availability Services synchronous start failed.
CRS-41053: checking Oracle Grid Infrastructure for file permission issues
PRVG-2031 : Owner of file "/u01/app/19.3.0/grid/bin/CommonSetup.pm" did not match the expected value on node "rac1". [Expected = "root(0)" ; Found = "grid(3002)"]
....

CRS-4000: Command Start failed, or completed with errors.

Even after unsetting http_proxy and trying to stop CRS got the following:

[root@rac1 ~]# crsctl start crs -wait
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.

[root@rac1 ~]# crsctl stop crs -f
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'rac1'

CRS-2795: Shutdown of Oracle High Availability Services-managed resources on 'rac1' has failed
CRS-4687: Shutdown command has completed with errors.
CRS-4000: Command Stop failed, or completed with errors

So https entry in http_proxy variable caused my CRS even not being able to stop.

Solution:

The solution is simple, find processes that were started during previous attempt and kill them (be careful, not to kill anything that is not started from GI home):

[root@rac1 ~]# ps -ef|grep d.bin

Make sure http_proxy is not set or instead of https there is http as a value:

[root@rac1 ~]# unset http_proxy

[root@rac1 ~]# echo $http_proxy

Or

[root@rac1 ~]# export http_proxy=http://test

Try to start CRS now:

[root@rac1 ~]# crsctl start crs -wait
