[oracle@dwrc4 ~]$ opmnctl status Can not resolve five.oracleateam.com for interface any opmnctl status: opmn is not running.I dug into the issue and it turned out that the cause of the problem is that the machine was configured to use DHCP and the hosts file had the 127.0.0.1 associated with both the hostname and localhost. So something like this:
127.0.0.1 five.oracleateam.com five localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6I was able to resolve the issue by changing /etc/hosts to the following:
127.0.0.1 localhost.localdomain localhost 10.99.2.112 five five.oracleateam.comOf course this means that each time the IP address changes you'll need to update the hosts file. You know me - "Never do anything manually if you can automate it" so I wrote an init script to update the hosts file automatically each time the VM boots. If you want that script let me know in the comments.
I also opened a bug (number 12530765) to track the issue. You can follow up with support on that bug to see when it will be patched. Note: this issue will probably apply to any of the 18.104.22.168 related patches with opmn including OHS.
If you want a copy of the script you can get it at GitHub
