Hello everyone,

I recently came across a very strange EBS startup issue that took me awhile to resolve. I just like to share it, just in case someone may run into the problem.

I started up EBS application by executing adstrtal.sh and got the following error from the log:

09/10/15-14:38:21 :: adopmnctl.sh version 120.6
09/10/15-14:38:22 :: adopmnctl.sh: Starting Oracle Process Manager (OPMN)
.../ora/10.1.3/opmn/bin/opmnctl[31]: unlimited: 0403-009 The specified number is not valid for this command.
opmnctl: opmn start failed.
09/10/15-14:38:29 :: adopmnctl.sh: exiting with status 2

I followed basic troubleshooting tips to validate opmn.xml for corruption, look into opmn.dbg and opmn.log, etc. All EBS configuration files appear to be accurate.

After looking into deeper the opmn.log, I noticed the ONS started, but with a wrong server IP address (

15/09/23 16:49:18 [ons-internal] ONS server initiated
15/09/23 16:49:18 [pm-internal] PM state directory exists: /apps/eu01/inst/apps/eu01_ebsux1/ora/10.1.3/opmn/logs/states
15/09/23 16:49:18 [pm-internal] OPMN server ready. Request handling enabled.
15/09/23 16:49:18 [ons-listener],6205: BIND (Can't assign requested address)

I looked at the /etc/hosts file and noticed the server was mapped to 2 different IP addresses for some reason.

/etc/hosts loopback localhost # loopback (lo0) name/address ebsux1 ebsux1

The active network interface for the server is assigned to this IP

Removing the line containing the wrong IP address ( ebsux1) from /etc/hosts finally fixed the issue.
