Starting opmn - RCV: Permission denied

Question

Hallo,
today I got following problem. After installing the oracle http server the opmn runs. Then i installed apex and edited the dads.conf. When i now try to start the http server following message appears:
RCV: Permission denied
Communication error with the OPMN server local port.
Check the OPMN log files
The logfile is empty.
Could anybody help me?

Answer 1

First Identify the cause of this from opmn.log
steps to be done:
This could be a reason, the opmn has been started by some other user.
1. identify the opmn process at the user level
$ps -ef|grep opmn|grep -v grep
if you find the opmn as pids, just login as that user and kill -9 PID
after killing all the process by the particular user,
go to $AS_HOME/Apache/Apache/logs
find out the file owner httpd.pid
that file will be having the owner of previous start
login as that user remove the file.
Now login as oracle or any user who owns the opmn, use opmnctl to start the process. it should work fine.
