ADMU3028I: Conflict detected on port 8879. Likely causes: a) An
instance of
the server dmgr is already running b) some other process
is using
port 8879
ADMU3027E: An instance of the server may already be running: dmgr
ADMU0111E: Program exiting with error:
com.ibm.websphere.management.exception.AdminException:
ADMU3027E: An
instance of the server may already be running: dmgr
please advice.
thanks!!
port 8879 is the default SOAP port for the dmgr. You can change the
port numbers in
<was_root>/profiles/<dmgr_profile>/config/cells/<cell_name>/
<dmgr_nodename>/serverindex.xml
for example:
/opt/WebSphere/AppServer/profiles/dmgr/config/cells/wasCell/nodes/
dmgrNode/serverindex.xml
I had quite a few issues when changing the ports of the Deployment
Manager (because the port is often hardcoded in property files elsewhere).
IMO, an easier approach is to have one dmgr run on a specific IP address
and another dmgr on another, see

com.ibm.websphere.nd.doc/info/ae/ae/trun_multiplenic.html
I must admit, it looks like more trouble than it could save, but it
worked better for us, ymmv.
