I have found out the problem and solution for this OPMN error, its actually our Fusion team work
the error is caused by Port conflicts we believe
so by using these set of commands of opmnctl
usage: opmnctl [verbose] [<scope>] <command> [<options>]
verbose: print detailed execution message if available
Permitted <scope>/<command>/<options> combinations are:
scope command options
start - Start opmn
startall - Start opmn & all managed processe
stopall - Stop opmn & all managed processe
shutdown - Shutdown opmn & all managed proce
[<scope>] startproc [<attr>=<val> ..] - Start opmn managed processes
[<scope>] restartproc [<attr>=<val> ..] - Restart opmn managed processes
[<scope>] stopproc [<attr>=<val> ..] - Stop opmn managed processes
[<scope>] reload - Trigger opmn to reread opmn.xml
[<scope>] status [<options>] - Get managed process status
[<scope>] dmsdump [<attr>=<val>&..] - Get DMS stats
[<scope>] set [<attr>=<val> ..] - Set opmn log parameters
[<scope>] query [<attr>=<val>] - Query opmn log parameters
ping [<max_retry>] - Ping local opmn
validate [<filename>] - Validate the given xml file
config [<options>] - Modify the opmn xml file
help - Print brief usage description
usage [<command>] - Print detailed usage description
we have shutdown the opmn box and restarted all of its process
it did not happen in the first time itself i have to repeat this for a several times then the SOA suite is running normally
if any one faces this issue i can help
