Service Virtualization

Hello,

I've got the following error when stating IAM : 

11:12:23,144 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000001: Failed to start service org.wildfly.undertow.listener.default: org.jboss.msc.service.StartException in serv

On my first installation, it was running. 

I've tried a new installation on a new vm, and now I have the previous error.

Does someone have already met this error ?

This is a an error from the JBOSS application server (Wildfly) that failed to open a socket to listen for incoming connections due to attempting to open an IPv6 socket
Resolution
The JAVA_OPTS environment variable must be set to contain -Djava.net.preferIPv4Stack=true prior to starting the IdentityAccessManager

On Windows:
set JAVA_OPTS=-Djava.net.preferIPv4Stack=true

on Linux:
export JAVA_OPTS="-Djava.net.preferIPv4Stack=true"

Shiney, 

Tested with "export..." it does work.

But using -Djava.net.preferIPv4Stack=true, it does not work. Maybe you can explain me why ?

Benoit

Shiney 

Do you want/need a case to check this ?

Benoit

Benoit, can you check the permissions on  the .vmoptions file?  Looks like its not getting read.  

Shiney,

The permissions look good : 

-rwxr-xr-x 1 udvtst udvtst 13156 Mar 26  2018 IdentityAccessManager
-rw-r--r-- 1 udvtst udvtst   276 Oct 11 14:40 IdentityAccessManager.vmoptions

And the content (maybe I made something wrong) :

# Enter one VM parameter per line
# For example, to adjust the maximum memory usage to 512 MB, uncomment the following line:
# -Xmx512m
# To include another file, uncomment the following line:
# -include-options [path to other .vmoption file]
-Djava.net.preferIPv4Stack=true

Benoit

Benoit,  as per the instruction,  I think it will only works as ENV Variables.  And not in vmoptions file.  

On Windows:
set JAVA_OPTS=-Djava.net.preferIPv4Stack=true

on Linux:
export JAVA_OPTS="-Djava.net.preferIPv4Stack=true"

Thanks Shiney.

Proposed idea : Components automatically installable and configurable
